ssh hang issue

[Mark Musone]

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: 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
