Hi,

I have an odd problem with ssh connections only (it seems), from a =20
specific network, ie this doesn't happen when on the same LAN as the =20
ssh server. (and not all non-local networks, over the internet is fine)

If I try an connect to the server;
[root@servername log]# ssh -V
OpenSSH_3.9p1, OpenSSL 0.9.7a Feb 19 2003
[root@servername log]# rpm -qa| grep openssh
openssh-clients-3.9p1-8.RHEL4.15
openssh-server-3.9p1-8.RHEL4.15
openssh-3.9p1-8.RHEL4.15

from any client, example cygwin;
$ ssh -V
OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007

$ ssh username@servername
#it just hangs here for the client, and this can be replicated using =20
secureCRT client as well

The connection hangs at the following point, which corresponds to =20
these lines in the debug log;
Aug 14 14:36:01 servername sshd[495]: debug2: kex_derive_keys
Aug 14 14:36:01 servername sshd[495]: debug2: set_newkeys: mode 1

Aug 14 15:36:01 servername sshd[494]: debug2: monitor_read: 7 used =20

Aug 14 14:36:01 servername sshd[495]: debug2: input_userauth_request: =20
try method none
Aug 14 15:36:01 servername sshd[494]: debug1: PAM: initializing for "usernam=
e"

So I guess pam is trying to do something, which due to the network =20
settings of my client pc, is failing. Any idea what that could be?

Thanks,

Tom
