Session keeps running when you disconnect - can be handy for users, Recent UltraVNC servers also support it (, judging from the changelog). Has anyone else run into this issue? Any solutions? For now I'm just reverting back to mRemote. UltraVNC work fine as well. Updated embedded UltraVNC integration to the latest version (no longer Fixed issue where closing a session in the keep tab opened on disconnect would.

A custom web server or apache module would be straight-forward. If proxies are chained see next paragraph then the ssh one must be the first one. If ssh-agent is not active, then the ssh password needs to be entered in the terminal where x11vnc is running.
Up to 3 may be chained, separate them by commas in the order they are to be connected to. If there problems connecting to IPv6 hosts consider a relay like the included inet6to4 script. When the property is set to "host" or "host:port" establish a reverse connection. Using xprop 1 instead of vncconnect may work see the FAQ. Default: -vncconnect To use different names for these X11 properties e. By ending in a ". Lines can be commented out with the " " character in the usual way.
Note that since you completely control these local non-TCP access methods by file system permissions, etc. Note: if you want to restrict which network interface x11vnc listens on, see the -listen option below.
As a special case, the option "-localhost" implies "-listen localhost". A rare case, but for non-localhost -listen usage, if you use the remote control mechanism -R to change the -listen interface you may need to manually adjust the -allow list and vice versa to avoid situations where no connections or too many are allowed.
This mode is for either local connections or a tunnel endpoint where one wants the file permission of the unix socket file to determine what can connect to it. This mode currently requires the modified libvncserver bundled in the the x11vnc 0.
Perhaps the program that execs x11vnc has created a socketpair 2 to communicate over. First note that one can disable all tcp listening ports by specifying '-rfbport 0'. The option '-unixsockonly str' is functionally equivalent to '-unixsock str -rfbport 0' -listen6 str When in IPv6 listen mode "-6", listen only on the network interface with address "str".
Use this if name resolution is incorrectly set up and leads to long pauses as name lookups time out, etc. If "string" does not contain a comma "," the tuning applies only to normal clients. Otherwise the part before "," is for normal clients and the part after for view-only clients. Their presence in the string enables that type of input. This option is ignored when a global -viewonly is in effect all input is discarded in that case. This method uses XGrabKeyboard 3X11 and so it is not secure and does not rule out the person at the physical display injecting keystrokes by flooding the server with them, grabbing the keyboard himself, etc.
Some degree of cooperation from the person at the display is assumed. This is intended for remote help-desk or educational usage modes. Try -ungrabboth below might not work. Unfortunately due to the way the X server works, the mouse can still be moved around by the user at the physical display, but he will not be able to change window focus with it. Also some window managers that call XGrabServer 3X11 for resizes, etc, will act on the local user's input.
Again, some degree of cooperation from the person at the display is assumed. This is to allow window managers, etc. If you only want one of them, use the -R remote control to turn the other back on, e. The -passwd full-access password must also be supplied. See the descriptions below for how to supply multiple passwords, view-only passwords, to specify external programs for the authentication, and other features. If the filename is prefixed with "rm:" it will be removed after being read.
Perhaps this is useful in limiting the readability of the file. If the filename is prefixed with "read:" it will periodically be checked for changes and reread. It is guaranteed to be reread just when a new client connects so that the latest passwords will be used. If "filename" is prefixed with "cmd:" then the string after the ":" is run as an external command: the output of the command will be interpreted as if it were read from a password file see below.
If the command does not exit with 0, then x11vnc terminates immediately. The environment variables are set as in -accept. If "filename" is prefixed with "custom:" then a custom password checker is supplied as an external command following the ":". The command will be run when a client authenticates. If the command exits with 0 the client is accepted, otherwise it is rejected. The standard input to the custom command will be a decimal digit "len" followed by a newline.
Then follows len bytes which is the random challenge string that was sent to the client. This is then followed by len more bytes holding the client's response i. The latter will require customizing the VNC client as well. File format for -passwdfile: If multiple non-blank lines exist in the file they are all taken as valid passwords. Blank lines are ignored. For compatibility, as a special case if the file contains only two password lines the 2nd one is automatically taken as the viewonly password.
If none of these succeed x11vnc exits immediately. Once the password is stored the program exits. Called with one argument, that will be the file to store the prompted password in. Be sure to quote "string" if it contains spaces, shell characters, etc. If the external command returns 0 the client is accepted, otherwise the client is rejected.
See below for an extension to accept a client view-only. If x11vnc is running as root say from inetd 8 or from display managers xdm 1 , gdm 1 , etc , think about the security implications carefully before supplying this option likewise for the -gone option. If "string" is "popup" then a builtin popup window is used. The popup will time out after seconds, use "popup:N" to modify the timeout to N seconds use 0 for no timeout.
If "string" is "xmessage" then an xmessage 1 invocation is used for the command. Both "popup" and "xmessage" will present an option for accepting the client "View-Only" the client can only watch. This option will not be presented if -viewonly has been specified, in which case the entire display is view only.
Note that x11vnc blocks while the external command or popup is running other clients may see no updates during this period. So a person sitting a the physical display is needed to respond to an popup prompt. More -accept tricks: use "popupmouse" to only allow mouse clicks in the builtin popup to be recognized. Similarly use "popupkey" to only recognize keystroke responses. These are to help avoid the user accidentally accepting a client by typing or clicking.
The default is to center the popup window. Unlike -accept, the command return code is not interpreted by x11vnc. The "popup" actions apply as well. If the [list] string begins with the character "! See below for per-user options that can be applied. A familiar "login:" and "Password:" dialog is presented to the user on a black screen inside the vncviewer.
The connection is dropped if the user fails to supply the correct password in 3 tries or does not send one before a 45 second timeout. Existing clients are view-only during this period. If the first character received is "Escape" then the unix username will not be displayed after "login:" as it is typed.
This could be of use for VNC viewers that automatically type the username and password. Since the detailed behavior of su 1 can vary from OS to OS and for local configurations, test the mode before deployment to make sure it is working properly. Another source of potential problems are PAM modules that prompt for extra info, e. These logins will fail as well even when the correct password is supplied.
Method 1 ensures the traffic is encrypted between viewer and server. A PEM file will be required, see the discussion under -ssl below under some circumstances a temporary one can be automatically generated. Method 2 requires the viewer connection to appear to come from the same machine x11vnc is running on e. And that the -stunnel SSL mode be used for encryption over the network. If it does, then the -ssl or -stunnel requirement will be dropped since it is assumed you are using ssh for the encrypted tunnelling.
One should never do this i. This also disables the localhost requirement for reverse connections see below. Note that use of -localhost with ssh 1 and no -unixpw is roughly the same as requiring a Unix user login since a Unix password or the user's public key authentication is used by sshd on the machine where x11vnc runs and only local connections from that machine are accepted. Regarding reverse connections e. Please use a ssh or stunnel port redirection to the viewer machine to tunnel the reverse connection over an encrypted channel.
In -inetd mode the Method 1 will be enforced not Method 2. With -ssl in effect reverse connections are disabled. If you override this via env. Tip: you can also have your own stunnel spawn x11vnc in -inetd mode thereby bypassing inetd. See the FAQ for details. The user names in the comma separated [list] may have per-user options after a ":", e. It ALSO implies all users are allowed to log in after supplying a valid password.
If [list] begins with the "! If the password is correct 'Y user' is printed and the program exit code is 0. If the password is incorrect it prints 'N user' and the exit code is 1. If there is some other error the exit code is 2. This feature enables x11vnc to be a general unix user password checking tool; it could be used from scripts or other programs. The output of the command is not printed, the program or script must manage that by some other means.
The exit code of x11vnc will depend on the exit code of the command that is run. Use -nounixpw to disable unixpw mode if it was enabled earlier in the cmd line e. All of the above -unixpw options and constraints apply. This mode requires that the encrypted passwords be readable. NIS is not required for this mode to work only that getpwnam 3 return the encrypted password is required , but it is unlikely it will work as an ordinary user for most modern environments unless NIS is available.
Looked at another way, if you do not want to use the su 1 method provided by -unixpw i. The first line of its stdin will be the username and the second line the received password. If the command exits with status 0 success the VNC user will be accepted. It will be rejected for any other return status. Dynamic passwords and non-unix passwords, e. LDAP, can be implemented this way by providing your own custom helper program. Note that the remote viewer is given 3 tries to enter the correct password, and so the program may be called in a row that many or more times.
If a list of allowed users is needed to limit who can log in, use -unixpw [list] in addition to this option. The first two lines of input are the username and passwd as in the normal case described above. Here is an example script note it has a hardwired bogus password "abc"! A real example would use ldap lookup, etc! See also "-passwdfile custom Note: if a -display occurs later on the command line it will override the -find setting. For this and the next few options see -display WAIT VT is the Linux virtual terminal of the X server.
Note: if a -display occurs later on the command line it will override the -create setting. Example: -svc Note: if a -display, -unixpw, -users, or -ssl occurs later on the command line it will override the -svc setting. Note: if a -display, -unixpw, -users, or -ssl occurs later on the command line it will override the -xdmsvc setting.
Subsequent re-connections will only require the -unixpw password. See the discussion under -display WAIT See -display WAIT: for more info. The -localhost option constrains connections to come in via a SSH tunnel which will require a login. Subsequent re-connections will only only require the SSH login. Normally in a -unixpw mode the VNC client must supply a valid username and password to gain access. They will then supply a username and password directly to the greeter.
Note that if the user re-connects and supplies his username and password in the unixpw dialog the xdmcp greeter is skipped and he is connected directly to his existing X session. The special options after a colon at the end of the username e. The username is ignored but the colon options are not. The default message is 2 lines in a small font, set the env. You can also supply host:port to redirect to a different machine. Probably the only reason to use the -redirect option is in conjunction with SSL support, e.
Xvnc or vnc. This mode only allows one redirected connection. The -forever option does not apply. Use -inetd or -loop for persistent service. A special usage mode for the normal -display option. Useful with -unixpw, but can be used independently of it. This could be useful for delaying opening the display for certain usage modes say if x11vnc is started at boot time and no X server is running or users logged in yet. If the string is, e. One can also insert a geometry between colons, e.
Most people use these instead of creating their own script. After the user logs in successfully, these options will be applied to the VNC screen. In the login panel, press F1 to get a list of the available options that you can add after the username. It sets the width and height of the new display, and optionally the color depth as well. You can also supply "gnome", "kde", "twm", "fvwm", "mwm", "dtwm", "wmaker", "xfce", "lxde", "enlightenment", "Xsession", or "failsafe" same as "xterm" to have the created display use that mode for the user session.
To set any other options, the user can use the gui x11vnc -gui connect or the remote control method x11vnc -R opt:val during his VNC session. This could be very useful on SunRays and also any system where multiple users share a given machine.
The user does not need to remember special ports or passwords set up for his desktop and VNC. You can have the x11vnc inetd spawned process run as, say, root or nobody. Note: there will be a 2nd SSL helper process that will not switch, but it is only encoding and decoding the encrypted stream at that point. NOTE: The option "-find" is an alias for this mode.
To have this default script printed to stdout e. If your X server s have a login greeter that exclusively grabs the Xserver, then xdpyinfo blocks forever and this mode will not work. See www. This is usually done in -inetd mode to run on, say, port and allow the Java vncviewer to be downloaded by client web browsers. The ":" is optional. Ranges n-m e. On some systems lsof 1 can be very slow. Set the env. This is the only time x11vnc tries to actually start up an X server.
NOTE: The option "-create" is an alias for this mode. Xdummy only works on Linux. Xvfb is available on most platforms and does not require root. When x11vnc exits i. The user must exit the X session in the usual way for it to terminate or kill the X server process if all else fails. This can be used from, say, inetd 8 to provide a means of definitely getting a desktop either real or virtual on the machine.
If for some reason you do not want x11vnc to ever try to find an existing display set the env. You can specify the preferred X server order via e. The the case "X" means try to start up a real, hardware X server using xinit 1 or startx 1. If there is already an X server running the X case may only work on Linux see startx 1. You can make this be a wrapper script if you like it must handle :N, -geometry, and -depth and other X server options.
The user will have to supply his username and password one more time but he gets to select his desktop type so that can be useful. This seems to be: for gdm in gdm. If you set the env. In this case it will start up Xvnc as above if needed, but instead of polling it in its normal way, it simply does a socket redirection of the connected VNC viewer to the Xvnc. So in Xvnc. This should be faster then x11vnc's polling method, but not as fast as connecting directly to the Xvnc with the VNC Viewer.
Most of x11vnc's options do not apply in this mode. To control when and how VeNCrypt is used, specify the mode string. If mode is "never", then VeNCrypt is not used. If mode is "support" the default then VeNCrypt is supported.
If mode is prefixed with "nodh:", then Diffie Hellman anonymous key exchange is disabled. If mode is prefixed with "nox", then X key exchange is disabled. To disable all Anonymous Diffie-Hellman access susceptible to Man-In-The-Middle attack you will need to supply "-vencrypt nodh:support -anontls never" or "-vencrypt nodh:only" If mode is prefixed with "newdh:", then new Diffie Hellman parameters are generated for each connection this can be time consuming: secs; see -dhparams below for a faster way rather than using the fixed values in the program.
Using fixed, publicly known values is not known to be a security problem. Otherwise in -unixpw mode the normal login panel is provided. The -vencrypt option only fine-tunes its operation. If mode is "only", then the similar VeNCrypt protocol is not simultaneously supported. If mode is prefixed with "newdh:", then new Diffie Hellman parameters are generated for each connection this can be time consuming: secs; see -dhparams below for a faster way rather than using the fixed values in the program.
This setting applies to VeNCrypt as well. See the description of "plain:" under -vencrypt. The -anontls option only fine-tunes its operation. You must also supply the -ssl If so, use the parameters in "file". By default a fixed set is used. If you do not want to do that you can specify "newdh:" to the -vencrypt and -anontls options to generate a new set each session.
If that is too slow for you, use -dhparams file to a set you created manually via "openssl dhparam -out file " -nossl Disable the -ssl option see below. This requires libssl support to be compiled into x11vnc at build time. If x11vnc is not built with libssl support it will exit immediately when -ssl is prescribed. See the -stunnel option below for an alternative. The connecting VNC viewer SSL tunnel can at its option authenticate this server if it has the public key part of the certificate or a common certificate authority, CA, is a more sophisticated way to verify this server's cert, see -sslGenCA below.
This authentication is done to prevent Man-In-The-Middle attacks. If [pem] is empty or the string "SAVE" then the openssl 1 command must be available to generate the certificate the first time. On subsequent calls if that file already exists it will be used directly.
However in -inetd and -bg modes there will be no prompting for a passphrase in either case. If [pem] is "TMP" and the openssl 1 utility command exists in PATH, then a temporary, self-signed certificate will be generated for this session. If openssl 1 cannot be used to generate a temporary certificate x11vnc exits immediately.
The temporary cert will be discarded when x11vnc exits. If successful in using openssl 1 to generate a temporary certificate in "SAVE" or "TMP" creation modes, the public part of it will be displayed to stderr e. For such binaries, consider using the -stunnel option for SSL encrypted connections. In some situations i. Set to zero to poll forever. Set to a negative value to use the builtin setting. The default timeout for that is 20sec.
Useful when scripting SSL connections e. This can be used as a method to replace standard password authentication of clients. If "path" is a directory it contains the client or CA certificates in separate files. If path is a file, it contains one or more certificates. See special tokens below.
See the stunnel 8 manpage for details. Then you can point -sslverify to the HASH subdir. As a kludge, use a token like.. Note that if the "CA" cert is loaded you do not need to load any of the certs that have been signed by it. You will need to load any additional self-signed certs however. Examples: x11vnc -ssl -sslverify CA x11vnc -ssl -sslverify self:fred,self:jim x11vnc -ssl -sslverify CA,clients Usually "-sslverify CA" is the most effective.
CA management is not needed. That way the administrator could generate a single CA key with -sslGenCA and distribute its certificate part to all of the workstations. Optionally, the admin could also make it so the VNC clients themselves are authenticated to x11vnc -sslGenCert client On the VNC client side, they will need to be "imported" somehow. This setting applies for both -ssl and -stunnel modes. See the OpenSSL and stunnel 8 documentation for more info.
This option only applies if -sslverify has been supplied: it checks for revocation along the certificate chain used to verify the VNC client. The -sslCRL setting will be ignored when -sslverify is not specified. Only rarely will one's x11vnc -ssl infrastructure be so large that this option would be useful since normally maintaining the contents of the -sslverify file or directory should be enough.
To create a CRL file with revoked certificates the commands 'openssl ca -revoke This command also creates directories where server and client certs and keys will be stored. The openssl 1 program must be installed on the system and available in PATH.
You will be prompted for information to put into the CA certificate. The info does not have to be accurate just as long as clients accept the cert for VNC connections. You will also need to supply a passphrase of at least 4 characters for the CA private key. One will need to "import" this certificate in the applications, e.
Web browser, Java applet plugin, stunnel, etc. Next, you can create and sign keys using the CA with the -sslGenCert option below. After the Certificate is generated x11vnc exits; the VNC server is not run.
The type of key to be generated is the string "type". It is either "server" i. Note that typically only "server" is used: the VNC clients authenticate themselves by a non-public-key method e. VNC or unix password. An arbitrary default name you want to associate with the key is supplied by the "name" string. You can change it at the various prompts when creating the key.
If name is left blank for clients keys then "nobody" is used. If left blank for server keys, then the primary server key: "server. If "name" begins with the string "req:" then only a key. You can then send the. Thawte and then combine the. The distinction between "server" and "client" is simply the choice of output filenames and sub-directory. And similarly makes it easy for the -sslverify option to pick up your client certs. There is nothing special about the filename or directory location of either the "server" and "client" certs.
You can rename the files or move them to wherever you like. Note you cannot recreate a cert with exactly the same distiguished name DN as an existing one. Similar to -sslGenCA, you will be prompted to fill in some information that will be recorded in the certificate when it is created.
Tip: if you know the fully-qualified hostname other people will be connecting to, you can use that as the CommonName "CN" to avoid some applications e. You will also need to supply the CA private key passphrase to unlock the private key created from -sslGenCA. This private key is used to sign the server or client certificate. The "server" certs can be used by x11vnc directly by pointing to them via the -ssl [pem] option.
This one would be used by simply typing -ssl SAVE. The pem file contains both the certificate and the private key. Once that is done you can delete the "client" private key file on this machine since it is only needed on the VNC viewer side.
The, e. NOTE: It is very important to know one should generate new keys with a passphrase. Otherwise if an untrusted user steals the key file he could use it to masquerade as the x11vnc server or VNC viewer client. You will be prompted whether to encrypt the key with a passphrase or not.
It is recommended that you do. One inconvenience to a passphrase is that it must be typed in EVERY time x11vnc or the client app is started up. For that key to be used e. The "SAVE" notation described under -ssl applies as well. After the Key file is encrypted the x11vnc command exits; the VNC server is not run. In addition the public certificate is also printed.
The openssl 1 program must be in PATH. Basically the command "openssl x -text" is run on the pem. After the info is printed the x11vnc command exits; the VNC server is not run. Giving a client or server cert shortname will also try a lookup e.
This is a useful way for other OpenSSL applications e. The scripts are printed to stdout and then the x11vnc program exits. This external tunnel method was implemented prior to the integrated -ssl encryption described above. It still works well and avoids the requirement of linking with the OpenSSL libraries. This mode requires stunnel to be installed on the system and available via PATH n. Version 4. See the -ssl option for more info on certificate files.
Whether or not your stunnel has its own certificate depends on your stunnel configuration; stunnel often generates one at install time. See your stunnel documentation for details. In any event, if you want to use this certificate you must supply the full path to it as [pem].
Note: the file may only be readable by root. If [pem] is not supplied, "SAVE" is assumed. The -localhost option is enforced by default to avoid people routing around the SSL channel. Unfortunately not too many do this. See the information about SSL viewers under the -ssl option. Note that for the Java viewer applet usage the "? In general, it is also not too difficult to set up an stunnel or other SSL tunnel on the viewer side.
A simple example on Unix using stunnel 3. NOTE: It is recommended that you use SSL via the -ssl option instead of this option because SSL is well understood and takes great care to establish unique session keys and is more compatible with other software.
Or if you must interface with a symmetric key tunnel that you do not have control over. See the OpenSSL documentation for more info. The keysize is bits except for aes Example: -enc blowfish:. The other side must read these and initialize their cipher with them. These values make the session key unique without them the security is minimal.
Similarly, the other side must send us its random salt and IV with those same lengths. The cipher is then seeded with keystr and uses the random initialization vector as its first block. To modify the amount of random salt and initialization vector use cipher n,m where n is the salt length and m the initialization vector length. The cipher 1st arg is basically the same syntax as we use above. For both ways of using the viewer, you can specify the salt,ivec sizes in GUI or, e.
GET is taking place and handle it accordingly. The URL would be, e. However, this heuristic adds a few seconds delay to each connection and can be unreliable especially if the user takes much time to ponder the Certificate dialogs in his browser, Java VM, or VNC Viewer applet. That's right 3 separate "Are you sure you want to connect? If [port] is not provided or is 0 , one is autoselected.
The URL to use is printed out at startup. The SSL Java applet directory is specified via the -httpdir option. If not supplied, -https will try to guess the directory as though the -http option was supplied. For example, one could redir from mygateway. This option does not work in -stunnel mode. As mentioned above, this mode will NOT work with the -ssl, -stunnel, or -enc encryption options.
Note that is it equivalent to '-enc none' i. This mode could also be useful for SSH tunnels since it means only one port needs to be redirected. The -httpsredir option may also be useful for this mode when using an SSH tunnel as well as for router port redirections. By default the remote sshd is usually configured to listen only on localhost for rport, so the viewer may need to ssh -L redir to "host" as well See SSVNC to automate this.
The sshd setting GatewayPorts enables listening on all interfaces for rport; viewers can reach it more easily. If disp is greater than the value is used as the port. Use a negative value to force a low port, e. By default the remote ssh will issue a 'sleep ' to wait for the incoming connection for 5 mins. If the remote SSH server is on a non-standard port i.
It tries by looking at ps 1 output. If x11vnc is not running as root this option is ignored. Why use this option? In general it is not needed since x11vnc is already connected to the X display and can perform its primary functions. In particular under GNOME and KDE to implement the "-solid color" feature external commands gconftool-2 and dcop unfortunately must be run as the user owning the desktop session.
Since this option switches userid it also affects the userid used to run the processes for the -accept and -gone options. It also affects the ability to read files for options such as -connect, -allow, and -remap and also the ultra and tight filetransfer feature if enabled. Note that the -connect file is also sometimes written to.
So be careful with this option since in some situations its use can decrease security. In general the switch to a user will only take place if the display can still be successfully opened as that user this is primarily to try to guess the actual owner of the session. Example: "-users fred,wilma,betty". What happens next? Under display managers it may be a long time before the switch succeeds i.
The latter i. Use the following notation to associate a group with a user: user1. Note that initgroups 2 will still be called first to try to switch to ALL of a user's groups primary and additional groups. Only if that fails or it is not available then the single group specified as above or the user's primary group if not specified is switched to with setgid 2.
This sort of setting is only really needed to make the ultra or tight filetransfer permissions work properly. Otherwise a user may be able to log in as another. This command can be of use in checking: "openssl x -text -in file. That user needs to be able to open the X display and any files of course. So it "lurks" waiting for anyone to log into an X session and then connects to it.
To enable a different searching mode, if the first user in the list is something like ":0" or "" that indicates a range of DISPLAY numbers that will be tried regardless of whether they are in the utmpx database for all users that are logged in.
Also see the "-display WAIT They are not recommended for use on machines with untrustworthy local users. Remote displays can be polled this way: be careful this can use large amounts of network bandwidth. This is also of use if the local machine has a limited number of shm segments and -onetile is not sufficient. Ignored unless -noshm is set. Limits shm segments used to 3. To disable any automatic shm reduction set the env.
The [color] is optional: the default color is "cyan4". For a different one specify the X color rgb. This also works on native MacOSX. Other desktops won't work, send us the corresponding commands if you find them. If x11vnc guesses your desktop incorrectly, you can force it by prefixing color with "gnome:", "kde:", "cde:", "xfce:", or "root:". Update: -solid no longer works on KDE4.
This mode works in a limited way on the Mac OS X Console with one color 'kelp' using the screensaver writing to the background. If one of the items on the list is the string "noptr" the mouse pointer will not be allowed to go into a blacked out region.
Use "-noxwarppointer" if you do not want this. For use on legacy systems, e. See the xrandr 1 manpage and run 'xrandr -q' for more info. It is best to be viewing with a vncviewer that supports the NewFBSize encoding, since it knows how to react to screen size changes. Otherwise, LibVNCServer tries to do so something reasonable for viewers that cannot do this portions of the screen may be clipped, unused, etc.
If a resize event is received, the full -xrandr mode is enabled. To disable even checking for events supply: -noxrandr. This mode could be useful on a handheld with portrait or landscape modes that do not correspond to the scanline order of the actual framebuffer. If you do not want the cursor shape to be rotated prefix "string" with "nc:", e.
Shortly afterwards the framebuffer is replaced with the real one. This is intended for use with vncviewers that do not support NewFBSize and one wants to make sure the initial viewer geometry will be big enough to handle all subsequent resizes e. In -unixpw mode this sets the size of the login screen. Use "once:WxH" it ignore padgeom after the login screen is set up. Same as "-logfile file".
To append to the file use "-oa file" or "-logappend file". This option could be useful by wrapper script to detect when x11vnc is ready. The file is created at startup if it does not already exist or if "file" is prefixed with "create:". If the file is created, the x11vnc PID is placed in the file. Otherwise the files contents is not changed.
Use prefix "nocreate:" to prevent creation. This is a convenience utility to avoid shell script wrappers, etc. You may specify as many of these as needed on the command line. Same as -copying and -warranty. The -quiet option does not eliminate all informational output, it only reduces it. It is ignored in most auxiliary usage modes, e. Messages to stderr are lost unless -o logfile is used. Also useful in resolving cases where a Keysym is bound to multiple keys e. Default: -modtweak If you are having trouble with with keys and -xkb or -noxkb, and similar things don't help, try -nomodtweak.
On some HP-UX systems it is been noted that they have an odd keymapping where a single keycode will have a keysym, e. You can check via "xmodmap -pk" or the -dk option. The failure is when you try to type " " it yields "3". This is powerful and should be tried if there are still keymapping problems when using -modtweak by itself. The default is to check whether some common keysyms, e. To disable this automatic detection use -noxkb.
When -xkb mode is active you can set these env. They apply only when there is ambiguity as to which key to choose i. If it is do not artificially press Shift to generate the keysym. If one side has CapsLock on and the other off and the keyboard is not behaving as you think it should you should correct the CapsLock states hint: pressing CapsLock inside and outside of the viewer can help toggle them both to the correct state.
Also try -nomodtweak for a possible workaround. Nevertheless your capitalized letters come in over the wire and are applied correctly to the x11vnc-side X server. Note this mode probably won't do what you want in -nomodtweak mode. See also -capslock above. Perhaps these are keycodes not on your keyboard but your X server thinks exist. Currently only applies to -xkb mode.
Run 'xmodmap -pk' to see your keymapping. Only use this option if you observe problems with some keystrokes. Added Keysyms will be removed periodically and also when x11vnc exits. The Lock modifiers are skipped. Used to clear the state if the display was accidentally left with any pressed down. Format is one pair of Keysyms per line can be name or hex value separated by a space.
If no file named "string" exists, it is instead interpreted as this form: key1-key2,key3-key4, To map a key to a button click, use the fake Keysyms "Button1", This way those little used keys can be used to generate bigger hops than the Up and Down arrows provide. One can scroll through text or web pages more quickly this way especially if x11vnc scroll detection is active. Use Button44, Button12, etc. To disable a keysym i. Dead keys: "dead" or silent, mute keys are keys that do not produce a character but must be followed by a 2nd keystroke.
This is often used for accenting characters, e. Note that this interpretation is not part of core X11, it is up to the toolkit or application to decide how to react to the sequence. However some VNC viewers send the keysyms "grave", "acute" instead thereby disabling the accenting. To work around this -remap can be used. Additional remaps may also be supplied via commas, e. This works around a repeating keystrokes bug triggered by long processing delays between key down and key up client events: either from large screen changes or high latency.
Default: -norepeat You can set the env. Note: your VNC viewer side will likely do autorepeating, so this is no loss unless someone is simultaneously at the real X display. Use "-norepeat N" to set how many times norepeat will be reset if something else e. X session manager undoes it. The default is 2. Use a negative value for unlimited resets. Intended for use with Win2VNC and x2vnc dual-monitor setups. To work around apps setting the selection too frequently and messing up the other end.
You can actually supply a comma separated list of directions, including "debug" to turn on debugging output. The "mode" string is optional and is described below. The default is to show some sort of cursor shape s. How this is done depends on the VNC viewer and the X server. Use -nocursor to disable cursor shapes completely.
Some VNC viewers support the TightVNC CursorPosUpdates and CursorShapeUpdates extensions cuts down on network traffic by not having to send the cursor image every time the pointer is moved , in which case these extensions are used see -nocursorshape and -nocursorpos below to disable. For other viewers the cursor shape is written directly to the framebuffer every time the pointer is moved or changed and gets sent along with the other framebuffer updates.
In this case, there will be some lag between the vnc viewer pointer and the remote cursor position. If the X display supports retrieving the cursor shape information from the X server, then the default is to use that mode. A similar overlay scheme is used on IRIX. Xorg e. This can be disabled with -nocursor, and also some values of the "mode" option below. Note that under XFIXES cursors with transparency alpha channel will usually not be exactly represented and one may find Overlay preferable.
See also the -alphacut and -alphafrac options below as fudge factors to try to improve the situation for cursors with transparency for a given theme. The "mode" string can be used to fine-tune the displaying of cursor shapes. It can be used the following ways: "-cursor arrow" - just show the standard arrow nothing more or nothing less. Some desktops such as GNOME cover up the root window completely, and so this will not work, try "X1", etc, to try to shift the tree depth.
On high latency links or slow machines there will be a time lag between expected and the actual cursor shape. This is a complete hack, but may be useful in some situations because it provides a little more feedback about the cursor shape.
This is useful if you want to be able to see Drag-and-Drop cursor icons, etc. Note: To work around a crash in Xorg 1. The Xorg crash occurred right after a Display Manager e. GDM login. Added GPO and system setting option to disable a website's credential autofill after a delay of one minute.

Issue seems to confirm this has been a problem for a while. Message: VncSharp Disconnected. I run into this and similar problems a lot for VNC connections. Installing UltraVNC on your client system and creating an External Tool in mRemote like the below might get you a halfway usable setup:. It's been an issue for a long time - for example see issues , and the latter two are the inspiration for the above. That does work with some degree of success I'd still like to see the integrated VNC support working, though.
I also have this problem. Using 1. Frequent disconnects for me too, although we mostly use UltraVNC's server occasionally in our environment. The UltraVNC client typically has no issues. Same here. I've noticed it happens more frequently when something is running fullscreen on the host machine like firefox or virtualbox , although I don't understand how that would affect the viewer in any way. When it's not disconnecting, mouse movement is poorly responsive and slow.
If I shut down the fullscreen apps the connection stabilizes. The issue isn't the host, running the apps direct on the machine are snappy and have no issues. If the remote machine has any of the programs full-screened then the connection will drop at random and show that I closed the connection. However, if there is a full-screen windowed program it maintains the connection without issue. Skip to content. Star 6. New issue. Jump to bottom. Labels 1. Copy link.
