Running on AIX, the unix sftp will connect to my site just fine, but the
Net::SFTP perl modules hangs at one point.
Here are the logs for the unix sftp:

Yeah. I've seen that too, when talking to certain types of server. It's
consistent (ie works or hangs) for a given server, though. I thought I'd
found the problem and wrote to the author but wasn't given the courtesy
of either a reply or a bounce. Oh, and my empirical "fix" moved the
goalposts but it still hung... sometimes.
In the end I wrote a Net::SFTP::Wrapper that emulated enough of Net::SFTP
for my requirements by using Expect on "sftp" itself. Ugly, but you're
welcome to it if it's any use to you.
