ssh problem

[Oche Satriani <oche_(_at_)_its_(_dot_)_ac_(_dot_)_id>]

i login to my openbsd box from ssh after a while a get a hang(all my input is 
not responding)

when i login from putty (windows ssh client) says "unexpected network errors 
100053"

my other services run normally and i've ping my openbsd box it works too.

Does anyone recognize my problem here ?

Thanks.
