SSH Login fails with "hash mismatch" on server, "missing begin marker" on client

This was an odd one. Recently I was setting up key-based ssh access for a server and the client was failing to connect with the generic "Permission denied (publickey,gssapi-keyex,gssapi-with-mic)." error.

I checked the server log (Centos, so /var/log/secure) and found an interesting "error: hash mismatch" message.

Using -v to get debugging info on the client end also gave me a message of "key_parse_private2: missing begin marker" - this was a red-herring and I suspect it happens often even when connections are working just fine.

When GPL software goes bad

Users of a popular open-source accounting system may have just updated to a license they would never have agreed to had the author actually told them it had changed. What's more, the author is actively censoring attempts to advise the userbase of the license change, and appears to be making an attempt to retrospectively re-license all prior versions as well.

New Server

The great news is - I have put in a new server! Yay!
You should find page loads far more expedient now, the old server (a dual P-II 400MHz with 256MB RAM, slow SCSI disks) was really struggling to do all the things I have it doing, and I now have a (very noisy) HP Netserver LP-2000r (dual P-III 1GHz with 512MB RAM, fastish SCSI disks) serving up the pages.
