Update fot the previous mail: The ssh_config with "ForwardX11 no" option listed below if part of the ssh_config file from the target host, not source one. I suppose I should be able to forward the X11 data to any client, where this is set to "yes", but I'm not. The ssh_config file on the target host seems to be irrelevant to my problem. Sorry for the multivalent statement in my previous mail.

Everything seems to work well, except X11-Forwarding. Sure, I have it on in config files: sshd_config: X11Forwarding yes X11DisplayOffset 10 XAuthLocation /usr/bin/X11/xauth ssh_config: ForwardAgent yes ForwardX11 no XAuthLocation /usr/bin/X11/xauth On some machines it works well. On one of the tru64 boxes and one RH Linux box I got the following message, when I try to start X-Windows application (i.e. xterm): # xterm channel 0: istate 4 != open channel 0: ostate 64 != open X connection to prfdec:11.0 broken (explicit kill or server shutdown). # Using ssh in debug mode: xterm debug: Received X11 open request. debug: fd 6 setting O_NONBLOCK debug: fd 6 IS O_NONBLOCK debug: channel 0: new [X11 connection from 195.113.56.1 port 2598] debug: X11 connection uses different authentication protocol. debug: X11 rejected 0 i1/o16 debug: channel 0: read failed debug: channel 0: input open -> drain debug: channel 0: close_read debug: channel 0: input: no drain shortcut debug: channel 0: ibuf empty debug: channel 0: input drain -> wait_oclose debug: channel 0: send ieof debug: channel 0: write failed debug: channel 0: output open -> wait_ieof debug: channel 0: send oclose debug: channel 0: close_write debug: X11 closed 0 i4/o64 debug: channel 0: rcvd ieof debug: channel 0: non-open channel 0: istate 4 != open channel 0: ostate 64 != open debug: channel 0: rcvd oclose debug: channel 0: input wait_oclose -> closed X connection to prfdec:12.0 broken (explicit kill or server shutdown). As far as I can see, there is something about "different authentication protocol". Please, how should I understand this message and what is the workaround for this ? Thanks a lot for your comments.
