I'm sending this now to the amanda-users list, I originally sent it to the linux-kernel ml but the only person who have answered my mail is Gene Heskett which also recommended me to try here.

I'm using amanda-2.4.4p2 but I have also tried 2.4.5b1-20040510 with the same results.

I have trouble upgrading from 2.6.5 to 2.6.6, I have narrowed it down
by trying the different rc releases. Between 2.6.6-rc1 and 2.6.6-rc2
something happens that make my amanda backups fail with the error
[bad CONNECT response].

Is this on the server or on the client or both?

If I do nothing else than boot to 2.6.6-rc1 from rc2 it works so it seems to be somthing with the kernel that is causing the

trouble, but I don't know how to investigate further.

This is the best debug info I've found so far.

You only send sendbackup.  Does it mean that amcheck does not give
any errors?

It seems that there is some networking issue.
Have you ruled out a misconfigured iptables?

Try with to see what happening on the wire with tcpdump.

...

Any ideas of how to investigate further? It seems that I'm the only
one with this problem beacause I can't find any other posts about
this. Unfortunately I don't have any other computers with tapedrives
on them to try and reproduce the problem (although it seems to be
about networking so a tapedrive might not be necessary to investigate
further).

You don't need a tapedrive at all.  Read the FILE-HOWTO in the
docs directory to setup virtual tapes. Takes only 5-10 minutes.

Thanks for any help.

Let me know if I need to post more info, don't want to write an unnecessary overly large e-mail.

You may always mail me personally the complete debugging info, or
packet trace if you like.
