i have two machines that are very slow to establish a ssh connection -- what i found was that if i did a -o option ssh -o GSSAPIAuthentication=no -N -L 2300:192.168.146.121:80 [EMAIL PROTECTED] every thing was fine and fast setting GSSAPIAuthentication=no in the sshd_config would not do the same thing it seems like it is messing with kebros for some reason when i run it without the the -o GSSAPIAuthentication=no option it complains about a bad realm and numeric address see below
