Bug Description

This one may be a needle in the haystack, but 1 of three hosts built with Karmic (one ubuntu straight, two mythbuntu) is giving me fits of bad packet length.

The one driving me crazy is attached (Via 1GHz i386 with Mythbuntu 9.10). tried rebuilding ssh keys and even reinstalled...

Not sure if this is a repeatable bug on other systems, but out of the box broken sounded like something to fire to the experts. can vnc in, so have local access.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we can't fix it because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem. We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures.
At a minimum, we need:
1. the specific steps or actions you took that caused you to encounter the problem,
2. the behavior you expected, and
3. the behavior you actually encountered (in as much detail as possible).
Thanks!

Hi,

When I ssh a solaris 8 server from Ubuntu 10.04 I get:

Bad packet length 1783261441.
Disconnecting: Packet corrupt

It works from any other ssh client I tried on Debian. Seems to be a bug from ubuntu side, ssh client or even ssl.

ssh -vv gives me:
