Not specifically, but the first things I would check: is sshd running on the affected machines? when trying to connect to the affected machines, do the clients give any error messages? or does the connection just time out? are there any relevant entries in the log files on the affected machines? specifically /var/log/messages and /var/log/auth.log are the affected machines using the same name server? and if they are, can the affected machines do forward and reverse lookups for the IP of the system you are trying to connect from? -Glenn >-- >John Brooks >john@day-light.com >_______________________________________________ >freebsd-questions@freebsd.org mailing list >http://lists.freebsd.org/mailman/listinfo/freebsd-questions >To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
