I'm seeing something unusual in 5.0p1. Let me start by saying that I'm on kind of an oddball system (HP NonStop). What I'm seeing is that at the end of an scp session, the server gets stuck in a loop. First I see a shutdown failure, followed by looping on an "ibuf_empty delayed efd 9/(0)" condition. This may have to do with some minor semantic differences in the way the NonStop socket layer works, as opposed to stock XPG4 or BSD sockets. What I'm really concerned about is the looping. Debugging output excerpted below. -- begin excerpt debug2: channel 0: rcvd adju...

.../var/xxx &' After looking at the debug logs and comparing the code, it seems there was a bug in the portable version during the adaptation of the 1.367 change (refactoring) of channels.c. The OpenBSD version looks correct, but for the portable version, the exit condition of channel_handle_efd_read() didn't get converted correctly, but somehow got copy-and-pasted from the rfd version. I couldn't find the change history for the portable version, so I can't when/how this happened. This should make the "force" condition the same as before the refactoring of the portab...

Just today I compilied openssh-2.1.1p1 on Debian Slink and Potato both to come out with the same problem. I am compiling them with openssl-0.9.5a.. The configure line I use for openssh is below: ./configure --sysconfdir=/etc/ssh --prefix=/usr --with-ssl-dir=../openssl-0.9.5a So I compile, do a make install restart the sshd daemon and everything seems fine. Then when I do a w at the prompt

I am trying to initiate an sftp session from a Linux (Redhat) to a LynxOs machine (where i have ported opnessh-2.9p1) and configured without PAM support (as I was not able to find PAM version for LynxOS operating system) I get the following error: $ sftp -P /home/telica -l telica -v ben select: Bad file descriptor read: Input/output error sftp> Can somebody help me asap on this?

can someone confirm this? it does not happen on openbsd. -------------- next part -------------- An embedded message was scrubbed...

I've been trying to cut down the size of openssh so I can run it on my Nokia 770. One thing which helps a fair amount (and will help even more when I get '-ffunction-sections -fdata-sections --gc-sections' working) is to have the option of compiling out privilege separation... Is it worth me tidying this up and trying to make it apply properly to the OpenBSD version? Does the openbsd
