So is there a way > to limit roots login from one or two machines? Hi Mark This is what I do: Disable root login via ssh entirely and set up 'sudo' and ssh-agents. You can make quite impressive sudo setups. Look at http://www.courtesan.com/sudo/ With this approach the root passwd are safe (both from ssh and from other admin/users) and you can exec any command on any server without the use of passwd if you use ssh-agents and every 'sudo' command is logged. You know who did this and that .. and when. Furthermore, add accounting on each server and add a central syslog(-ng) server (if not done allready) respectfully /per [email protected] > > -Mark > > _______________________________________________ > [email protected] mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-security > To unsubscribe, send any mail to > "[email protected]" _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-security To unsubscribe, send any mail to "[email protected]"
