"UseDns no" doesn't solve the problem because GSS Api needs reverse lookup. If (do not need GSS Authentication) then put "GSSAPIAuthentication no" in the host /etc/ssh/sshd_config else put your server ip and server name in the client /etc/hosts "xxx.xxx.xxxx.xxx yourserver.name" :) H.can _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
