Find the line in your rule-set that allows ssh-access (port 22). add to this line the -s or --source flag with the ip-address of the souce-box. providing the output-chaing allows all outgping traffic, that's all. Disableing iptables may not be a good idea security-wise. > Two user accounts receive mail continuously. I would like to have them > automatically logged on at boot time. Is this possible? How? that's a tricky one. what you may wnat to do is edit your inittab file and change one of the lines looking like this (on debian at least): 1:2345:respawn:/sbin/getty 38400 tty1 chagne the last part. what you could try (note that this is something i haven't tried) is install sudo and use: sudo -u <user> -H -s (check man for correct flags) at the correct user -H for the correct enviroment and -s to get a shell or chagne -s to i.e. start pine/mutt directly. good luck. > Thanks, > John > > > -- Andor Demarteau E-mail: andor@xxxxxxxxxxxx student computer science www: http://www.nl.linux.org/~andor UU based & VU guest-student jabber,icq,msn,voip: do ask ;) ----------- chairman Stichting Studiereizen STORM www: http://www.stistusto.nl vice-chairman USF Studentenbelangen executive committee 2002-2003 _______________________________________________ Blinux-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/blinux-list
