Hung connection over Juniper Tunnel

Fri Feb 6 13:43:13 EST 2009

Hello list!

So I recently reconfigured our office network to allow a permanent VPN  
connection to our data center. This consists of a Juniper SSG-520  
connected via a tunnel to a Juniper Netscreen-25 over a 100M leased  
NTT VPN (yes I'm tunneling over the VPN as it's the only way to make  
it routable.) Here is where OpenSSH come in. When I try and ssh to a  
machine on the other end of the tunnel, I can get past the  
authentication stage and then it just hangs and times out. Everything  
else works, ping, http, and dns (ICMP, TCP and UDP in other words.)  
More cryptically, I can effortlessly ssh with PuTTY from a windows  
box. It seems that OpenSSH (or the Unix TCP/IP stack) is the only  
thing affected. Now I'm the first to admit that this is most likely  
some sort of subtle MTU or low level TCP issue, and I'm guessing the  
OpenSSH is the canary in the coal mine, it would be great if I can get  
someone to tell me why it's freezing so that I can fix the actual cause.

There were several people complaining of similar issues, typically it  
turned out to be bad wireless drivers or broken routers, no direct  
cause was ever indicated.

Here is the (OpenSSH_5.1p1, OpenSSL 0.9.7l) client side debug output:
