Perhaps. I find this interesting though.

U:\>sftp -v -v -v
Connecting to
OpenSSH_5.1p1, OpenSSL 0.9.8k 25 Mar 2009
debug2: ssh_connect: needpriv 0
debug1: Connecting to [] port 22.

If I do the same thing, though I'm in bash, I get this line first:

debug1: Reading configuration data /etc/ssh_config

So, do you have this file?

I have to use control-C to stop this, as it hangs after the 'connecting
to' line.

This problem is independent of where I am connecting to.

Really. So you could debug on the server side then and see if there's any interaction. If not, it sounds like this is a problem with an outgoing firewall block or other BLODA <>.

Here is some output when run with bash. The first output successfully connects, the second one hangs. Since this issue is intermittent, I suspect it might not be a BLODA issue...

Yeah, probably true. Still worth a look though.


I had to use control-C to stop this, as it has been hanging at this
point for 5 minutes.

Yep, you're clearly getting a hang there. Have you tried this with another machine that wouldn't be a mirror image of the one you're using? Could be a machine specific configuration thing. If it doesn't work for you from more than 1 machine and it's not an external source like BLODA and it's not something on the server side, then it looks like you're stuck trying to debug this in the source.
