I have my home computer set up so that I can SSH in from work. I set up a public/private key so that I don't have to send a password. I have been doing this for several weeks with no problems at all, but it stopped working today. When I try to SSH in I get the following:

:~ myname$ ssh -l myname mycomputer.homedns.org
Enter passphrase for key '/Users/myname/.ssh/id_dsa':
Enter passphrase for key '/Users/myname/.ssh/id_dsa':
Enter passphrase for key '/Users/myname/.ssh/id_dsa':
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

I know I am entering the same password that I have always entered because I put it in my Keychain and double-checked it. Is there any way to find out what is going wrong? I know the most likely culprit is that I am entering the wrong password, but I know it is correct. Do I just have to set it all up again?

thanks,
kman

try ssh -v to see more verbose output, otherwise you can regenerate your key pairs and it should work fine again.

You are using dynamic DNS, no? The IP may have changed.

The work computer may have an old IP address cached. Try flushing the DNS cache.

on a mac:
sudo lookupd -flushcache

there must be a similar mechanism for the PC, if that's what you are using at work, but I don't know it.

Are these both Macs ?

I had never any luck with SSH key authentication between two Macs on the same network though. For some reason, it never worked.
