       Hello,

       I have a similar problem with SL4.1 ssh *client*
       when I connect to a Sun machine with an old ssh protocol 1
       server.

       If I connect to the same Sun with other ssh client server
       it is quite faster. 


#### rabeson:/u/robert > time ssh  mambo hostname           # from my SL4.1 machine
mambo

real    0m10.761s
user    0m0.041s
sys     0m0.012s
#

#### gottlieb:/u/robert > time ssh  -1  mambo hostname      # from Mandriva Linux release 2006.0 
mambo
0.03user 0.00system 0:00.75elapsed 5%CPU (0avgtext+0avgdata 0maxresident)k
0inputs+0outputs (0major+1272minor)pagefaults 0swaps

#### django:/u/robert > time ssh   mambo hostname           # from  Debian testing 
mambo

real    0m0.768s
user    0m0.013s
sys     0m0.007s

#### henocq:/u/robert > time ssh   mambo hostname            # old RedHat 6.2 (same old ssh client as 
mambo                                                                          the sun)

real    0m0.799s
user    0m0.060s
sys     0m0.000s

       Trying with a -v option one sees that the hang is between:

debug1: identity file /u/robert/.ssh/identity type 0
       and
debug1: Remote protocol version 1.5, remote software version SSF-1.2.27.8-static

       Hope this help.
