I usually connect to a remote headless server and could easily run remote X applications on the local X server. –enzotib Sep 16 '11 at 18:09 @enzotib -- thanks ; I didn't know that. –belacqua Sep 16 '11 at 18:23 @enzotib sorry, I didn't see your comment. Yes, I can open xterm on my local machine –Fabian Sep 16 '11 at 18:28 add a comment| 6 Answers 6 active oldest votes up vote 6 down vote If ssh is able to establish the connection, it will set DISPLAY to the proper value. Since you have X11DisplayOffset set to 10 (the default value), ssh will use the first available display starting at 10. If you see a value that's lower than 10¹, then something is interfering with the normal X11 forwarding set up by ssh, at least by overriding DISPLAY. The value :0 (or :0.0, the part after the dot is irrelevant) indicates the first display that was started on the machine, which in typical cases is the active session (or the graphical login prompt) on the machine's console. The most likely explanation for the behavior you observe is th

These scripts launch 5 xterms that are forwarded to me via ssh (using the -X option). At the moment I am debugging my code so I am http://unix.stackexchange.com/questions/117159/cannot-start-xterm-over-ssh-after-several-successes restarting my scripts every now and then. Everything works fine for a couple of runs, but after the N'th time (where N is a random number) I get theses error messages: xterm Xt error: Can't open display: localhost:10.0 xterm Xt error: Can't open display: localhost:10.0 xterm Xt error: Can't open display: localhost:10.0 xterm Xt error: Can't open display: localhost:10.0 xterm Xt error: Can't open display: localhost:10.0 After this I can continue to use ssh except for starting anything GUI-related, meaning that I can no longer start xterms remotely. My only workaround is to restart the ssh connection. Can I fix this somehow to never be bothered again by this?

To avoid this, run ssh -Y instead of ssh -X, or set the option ForwardX11Trusted yes in ~/.ssh/config. If you run ssh -v, you'll see the message “Rejected X11 connection after Forwar

It can use a number of transport protocols, including Unix sockets and TCP/IP sockets. Which mechanism is used, is determined by the format open display of the DISPLAY environment variable. When DISPLAY does not contain a hostname, e.g. it is set to :0, Unix sockets will be used. When it does contain a hostname, e.g. it is set to localhost:0.0, the X client application will try to connect to the server (even localhost as in the example) via TCP/IP sockets X has an authentication mechanism, which xterm xt error decides whether a client is allowed to connect to a server. As the Internet has become an increasingly hostile environment, it has become good practice to only open up services to the Internet when they are really needed. Recently in some Linux distributions, X is by default configured to listen only to localhost. That means that default X settings become more and more defensive and thus without tuning there are more and more reasons why remote communications attempts using X initially will fail. That's why the first time you try to run a remote X application on modern Linux distributions, it usually does not work. The most common error message by far is "Can't open display". In this case an X client application, for example xterm, reports an error Can't open display on startup, for instance xterm Xt error: Can't open display: localhost:0.0 The first thing to try is to ensure that you used a correct sequence of commands. One typical mistake is you use like xhost + on the client instead of the server (your workstation). If you have problems the
error: Can't open display: There is no DISPLAY variable in the environment, and you didn't tell the application with the -display flag either. The application assumes the empty string, but that is syntactically invalid. To solve this, be sure that you set the DISPLAY variable correctly in the environment (with setenv or export depending on your shell).
_X11TransSocketINETConnect: Can't connect: errno = 101 xterm Xt error: Can't open display: love.dial.xs4all.nl:0Errno 101 is ``Network is unreachable''. The application could not make a network connection to the server. Check that you have the correct DISPLAY set, and that the server machine is reachable from your client (it should be, after all you're probably logged in to the server and telnetting to the client).
_X11TransSocketINETConnect: Can't connect: errno = 111 xterm Xt error: Can't open display: love.dial.xs4all.nl:0Errno 111 is ``Connection refused''. The server machine you're trying to connect to is reachable, but the indicated server does not exist there. Check that you are using the right host name and the right display number. Alternatively, it is possible that the X server was configured not to listen to the usual TCP port. To find out if this is the case, see if the X server is started with the -nolisten tcp argument, and if so, remove it.
Xlib: connection to ":0.0" refused by server Xlib: Client is not authorized to connect to Server xterm Xt error: Can't open display: love.dial.xs4all.nl:0.0The client could make a connection to the server, but the server does not allow the client to use it (not authorized). Make sure that you have transported the correct magic cookie to the client, and that it has not expired (the server uses a new cookie when a new session starts). Next Previous Contents
