It is possible you are running out of file descriptors. Running out of fd's shows up in strange ways! Did you bounce ssh on both sides of the tunnel. More importantly on the receiving end ;). Try running ssh/scp with the -v flag set, it may give you some good info. Run tcpdump .. are you dropping a ton of packets? Do a simple ping to see if there is packet loss? Do a ifconfig are there a ton of errs on the interface you are leaving on/ receiving from?
If you see you are dropping a lot of packets but there are no interface err's you can encourage the person that admins the VPN to check it out!

I tried bouncing ssh at both ends... even doing a kill of all the processes of both ssh and sshd at both ends.
scp -v doesn't show any weirdness.
Ping works well, there's not an abnormal amount of errors in ifconfig.
Is the open file limit system wide, or user specific? Mine's set for 4096, I've tried killing off a bunch of rarely used services on both machines to get the file count down.
Now... this morning I'm noticing I can scp from the remote machine to the local machine, but not the other way around. In other words, from the remote machine, this works: scp qaddonline hughesm@10.1.0.19: But copying it back doesn't. scp hughesm@10.1.0.19:qaddonline .
(qaddonline is about a 2 meg file)
Also... from the local machine, iI can pull things down scp hughesm@10.21.2.184:qaddonline . but not push things up scp qaddonline hughesm@10.21.2.184:
This didn't work last night.
I can also now send small files (I tried one less than 1k) fine.
I'd also like to add there's 2 machines in the remote facility that both have identical behavior. So I'm thinking it's either the link or my local machine.
I'm no tcpdump expert, and both these machines have a good deal of traffic. What's an easy way to see if packets are getting dropped? (yeah, I suck at tcpdump filters).
Any other ideas on things to look for? -Marc
