| Subject: | Bad login performance with SSH2 |
Hello,
since Monday I'm trying to use Net::SSH::Perl within a script. I want to
have a constant connection to a remote host and execute hundreds of
commands during the session. Because of this I am forced to use SSH2. If
I use SSH1 the login is running very fast, but with SSH2 it takes about
20-30 seconds to login. In the debug output I can see that the login
"sleeps" on 2 positions. I already tried to login after changing various
settings (ssh-rsa, different ciphers, hmac-md5, etc.) without success.
By the way, it is also impossible for me to do pubkeyauth.
Do you have any idea why this happens?
Regards
Sebastian
