Simultaneous login requests to 'reach' a listening login as I think I've only screwed up pts0

A VNC connection to a machine on site and then using telnet (nope, telnet disabled)

A VNC connection to a machine on site and then a VNC connection to the server (VNC not running on this one).

Any suggestions to issue a remote reboot - as I said, it's not a major issue as I can have the server rebooted by someone on site.

Thanks

Serial connection are most useful in these cases, but after the fact this is not very helpful. I have also used cron jobs when doing remote admin on machine with good success, if changing firewall configs, I would revert he change and restart iptables, doing ssh configs same deal.

Another good thing is to have a generic local account that has sudo privileges assuming you have someone that can hope of the console for you.

As long as the changes you made did not toast anything a reboot is your likely only recourse.

Have you got 'magic script' turned on in samba? If not, have you got swat running and able to turn on magic script?

If you do then you could run a script which will run 'service sshd restart' for you.
