We installed openssh 3.1p1 on our Solaris 2.8 machine using gcc 2.95.2. During the installation, we modified ssh_config and sshd_config to enable X11 and agent forwarding. In sshd_config, we changed the following line to read: X11Forwarding yes In ssh_config, we changed the following two lines to read: ForwardAgent yes ForwardX11 yes Both files are set to permission readable

I'd like a feature whereby ssh puts itself in the background after the first successful X11 (or other port) forwarding. The reason for this is simple: error handling. If the application fails to open the X display and exits, then the client can still exit with the application's exit code. But if the application opens the X display successfully, then it can just display any errors by

I've been trying to cut down the size of openssh so I can run it on my Nokia 770. One thing which helps a fair amount (and will help even more when I get '-ffunction-sections -fdata-sections --gc-sections' working) is to have the option of compiling out privilege separation... Is it worth me tidying this up and trying to make it apply properly to the OpenBSD version? Does the openbsd

Hi! I am resending the following message about problems with utmp handling. * In the meantime I had some request in private mail from people asking whether I have new information. * The problem is still persistant in 2.9p2. * My own new investigations show, that the problem only appears with protocol 2, not with protocol 1, I therefore only started to note it when protocol 2 became the

Hi, If I enable "UseLogin" under AIX, I get the following message upon login: /dev/pts/2: 3004-004 You must "exec" login from the lowest login shell.
