Yet Another Compatibility Fix (SSH_MSG_CHANNEL_OPEN_FAILURE)
Hi,
SSH.COM/F-Secure version 2.0.xx sends/receives SSH_MSG_CHANNEL_OPEN_FAILURE
packets without the additional two strings (additional info/language tag) -
I think the SecSH drafts at that time didn't have those two strings.
Possibly some other implementations have this problem too. Anyway, a fix
for OpenSSH (against latest cvs tree) is included.
(This has been partiall...

Can't connect to server using protocol v2?
Is this really caused by a buggy server, or is this an interoperability
problem? It seems to work ok when I specify -o "protocol 1" on the command
line. Thanks,

Security suggestion concering SSH and port forwarding.
Hi,
sorry if it is the wrong approuch to suggest improvments to OpenSSH,
but here comes my suggestion:
I recently stumbled upon the scponly shell which in it's chroot:ed form is
an ideal solution when you want to share some files with people you trust
more or less.
The problem is, if you use the scponlyc as shell, port forwarding is still
allowed. This can of course be dissallowed in
