hi,
i also forgot to mention that i have disabled all windows shares,
and modified the .bash_profile such that the paths are minimal.
these did not help either. sorry for the previous poorly
formatted message.

hi,
i'm having a problem where my cygwin openssh sshd logins are
slow. i am using rsa key autologins. only a certain portion
of the login is slow. when i do a "ssh -x
<user>@<cygwinmachine>" from my linux box, the authentication
is immediately successful (the motd prints out immediately),
but then it takes about 5 seconds for the shell to appear. I
know that the shell is not slow in starting up, because in
/etc/passwd i've replaced the shell with the "date" command ,
and that takes an equally slow amount of time to get from the
motd to the shell program execution.
-- i've added the option "UseDNS no" to the sshd_config file,
to avoid reverse dns lookups.
-- "sshd" is setup as an XP service, with access to the
desktop
-- "ssh -vvv user@machine" doesn't show anything wrong. it
is virtually instantaneous until after printing the motd.
-- rsa key logins to a linux box on the same segment as the
windows give me an instantaneous shell.
the last thread i saw about sshd logins being slow was dated in
2001, and those were resolved by disabling the reverse dns
lookups (which i've done).
Any comments are appreciated. Thanks!
