Reverse DNS lookups on the remote machine???
routing issues on the remote machine/network ???
ARP issues ??
how about a tcpdump or an ethereal trace so we (you) can see whats going on
with the network level
also how about stracing the sshd and seeing whats going on on the processes
level?

Subject: ssh hang issue
I have ssh set up with authorized keys (no password required.)
Basically, I replaced a server with another- Added it to the authorized keys
list and set it up just like the old server but it hangs (as shown here by
ssh -v -v )
debug2: bits set: 517/1024
debug1: SSH2_MSG_KEX_DH_GEX_INIT sent
debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY
debug2: key_type_from_name: unknown key type '1024'
debug2: key_type_from_name: unknown key type '1024'
debug1: Host 'j23' is known and matches the RSA host key.

debug1: Authentications that can continue:
publickey,password,keyboard-interactive
debug1: Next authentication method: publickey
debug1: Trying private key: /root/.ssh/id_rsa
debug1: Offering public key: /root/.ssh/id_dsa
debug2: we sent a publickey packet, wait for reply
It'll sit like that for a good 3-4 minutes and then complete ok.
Anybody see this before?
TIA,
Dennis
