Hello,

I'm having problems with ssh-1.2.17. It stops randomly with the
errormessage "Local: Bad packet length 16844810." Is there anything I have
to change or upgrade to avoid this problem? I've checked the ssh homepage
for a faq but couldn't find any.

Some info you might need:

ssh client runs on a p2-266 with redhat 6.0 + redhat 6.0 updates + linux
2.2.10. The following ssh rpms are used:
ssh-extras-1.2.27-5i
ssh-server-1.2.27-5i
ssh-1.2.27-5i
ssh-clients-1.2.27-5i
This computer uses adlink 528ct ethernet card (ne2k-pci) connected to a 
"Motorola CableSURFR Wave Modem" to get to the internet. I'm connecting to
ace.ulyssis.student.kuleuven.ac.be, a p2-350 running linux 2.2.5-22 from
redhat rpm + redhat 6.0 with latest updates. I also uses the 1.2.17-5i
rpms. The problem is quite annoying, until now i had to resume typing this
email already 12 times.

Here's some output from tcpdump:
