openssh-2.3.0p1-1 with RedHat 6.2 - Bad packet length

[James]

I haven't been able to get scp to work with RedHat 6.2 (select: Bad file
descriptor), so...  I tried upgrading with openssh-2.3.0p1-1.src.rpm and
openssl-0.9.5a-3.src.rpm  No joy.  When running just ssh, I get
"Disconnecting: Bad packet length 795178083."

This seems to be a problem with sshd, since the 2.3 ssh client will work
fine with a 2.1 server (but not scp, which still gives "select: Bad file
descriptor".

Any suggestions?

Please Cc me on any response, as I'm not subscribed to the list.  Thanks.
