Neither scp nor sftp works (2.5.1p1 and Solaris 2.6) :(

[Olof Liungman]

Hi,

sorry about bothering you like this but despite several tries my recent
posts to ssh at clinet.fi never appear on that list, and I don't know where
else to turn.

I was unable to get sftp/scp to work when using OpenSSH 2.3.0p1. No one
could solve this problem and evenutally I was told to try "a recent
snapshot". Now I've installed 2.5.1p1, but still no cigarr :(.

I have OpenSSH installed on two Sun SPARC-boxes running Solaris 2.6. I
configured with PAM and TCP-wrapper support. The software compiled fine,
except for a few warnings. Normal ssh/slogin works great, both from one
Sun-box to another and from Windows (F-Secure 4.1 SSH Client) and Mandrake
Linux (2.3.0p1), using both public key authentication and normal password.
However, neither command line scp nor F-Secures sftp client work from any of
the machines to any of the sun boxes, nor between the Sun-boxes.

My config files are standard and the "subsystem"-entry looks just fine. I've
included the output (without IP-numbers and user names) on the client and
the server side below (the latter using "Loglevel DEBUG"). Everything just
dies after the SIGCHILD. What is going on?

Two other users have contacted me regarding my earlier, unanswered posts
concerning problems with sftp (then for v. 2.3.0p1) because they hade the
same problem.

Any help would be very appreciated as I've exhausted all options I can think
of.

Sincerely,
