When connecting to a Solaris 5.9 host using the latest openssh I am receiving a "lost connection" message.

This has been working fine for a long time now and if I roll back to openssh-3.8.0.1.2 all is well again.

Any idea what has changed in openssh-3.9.0.1 that would be causing this?
Any info that I can provide that would help?
I can provide an account on the sun box if it would help.

Later, Peach

When does the "lost connection" happen in the sequence of connection to the Sun machine?

Apparently very early on the program actually core's out.
I can send the core if you are interested....

Just a point of reference the sun box has not been changed or updated in probably a year.

Here's the debug output.

$ scp -v openssh-3.9.0.1-bin.tgz sunblade:
Executing: program /usr/local/bin/ssh host sunblade, user (unspecified), command scp -v -t .
lost connection
$ scp -v openssh-3.9.0.1-bin.tgz epeach@sunblade:
Executing: program /usr/local/bin/ssh host sunblade, user epeach, command scp -v -t .
lost connection

Digging back through the posting and found this looking like it
might still be open. There have been a few updates to openssh
that I don't see as addressing this posting. Does the latest (at this
time 3.9.0.1.4) still do the same with the Solaris box ?

Well I have been away for a while.

I just built out new laptop downloaded & installed all of the current software & ran into this again(or still) with the latest release.

Again if I roll back to the older version all is fine.

Any ideas? Need more info?

Just for clarity (on my part) is this the sequence of events still?

1) At Interix shell prompt
2) Run scp 3.9.x.x from Interix shell to connect to Sun box.
3) Debug (-v) output is not a lot (as shown in posting 3 above).
3) Then scp 3.9.x.x on Interix dumps core.

What's the byte size of the core file?
