slow to establish ssh problem

[rrk]

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   [e-mail] 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

********************************************
debug1: An invalid name was supplied
Cannot determine realm for numeric host address

debug1: An invalid name was supplied

*********************************************
90% of the time is spent on these  errors which do not appear when i use a cmd line -o option
(ssh -o GSSAPIAuthentication=no 192.xxx.xxx.xxx )

below is a snip with the -o option and without

with -o GSSAPIAuthentication=no
