My guess would be that the resolver library on your Linux box doesn't like
the format of your packet, or is munging it somehow so that the remote
server is rejecting it with a FORMERR response.

I'd try to determine what version of the resolver library you were using on
the Solaris 8 box and compare it with the version on the Linux box. If the
Linux box has a later version, you'll have to figure out why it's being so
picky and appease it. If the Linux box has an earlier version of the
resolver library, then I'd probably look for an RPM of a later version, or
update it manually from a freshly-downloaded-and-built BIND distribution.
