Re: sendbackup: critical (fatal): Can't dup2: Bad file number

Darin, Gunnar,

I committed a fix for this bug a few minutes ago.

Chris was right, this bug could only be seen with an UDP auth (bsd orbsdudp).

I should have posted a follow-up to an earlier post of mine which is
similar it this if not the same. Chris Ritson brought to my attention
that this is most likely being caused by using UDP to communicate with
the amanda client. After switching amanda from UDP to TCP the dup2, and
any other AWK, NAWK, issues went away and everything is working as expected.
