mac osx - ssh hangs without password prompt -- works in root or other accounts

I had ssh key based login working fine.
Then, I changed the hostname on my computer, and the key based login stopped working.
Seemed to make sense. the keys probably relied on my old hostname.
So, I deleted all of my keys and all the files in ~/.ssh/ and regenerated them (and changed the authorized_keys on the servers I connect to)

Now, any time I try to ssh, it just hangs without the password prompt, no matter where I an trying to ssh to--even servers where I don't have key based login set up. There is nothing in .ssh/config.

Moreover, when I 'su -' to root, ssh works perfectly. no problems at all. This only happens on my user account.

Below is some debugging info from ssh

ssh -vv mylogin@myremoteserver.com
OpenSSH_5.2p1, OpenSSL 0.9.8k 25 Mar 2009

debug1: SSH2_MSG_NEWKEYS received
debug1: SSH2_MSG_SERVICE_REQUEST sent
debug2: service_accept: ssh-userauth
debug1: SSH2_MSG_SERVICE_ACCEPT received

And then it just hangs here.....

Here is the dtruss (like strace but for OSX) output near the end where it hangs:

sudo dtruss ssh -vv mylogin@myremoteserver.com

select(0x4, 0x508200, 0x0, 0x0, 0x0)         = 1 0

write(0x2, "debug2: service_accept: ssh-userauth\r\n\0", 0x26)       = 38 0

read(0x4, "\0", 0x4)         = -1 Err#4

It seems to be trying ro read something and just hangs on this. If anyone has some suggestions or ideas, I would be very grateful!

Answer

For me, upgrading to Snow Leopard solved the issue. So, I think it was related to a bug in OSX.
