Hi, I'm a little stuck on getting reverse connection working reliably from embedded devices running dropbear 0.51 to Ubuntu 8.x openssh. Connecting to local reverse socket often fails (not always) with "ssh_exchange_identification: Connection closed by remote host" My devices can reverse ssh and open a port on my server always, but often when the server is creating the reverse

I am running OpenSSH 2.9p1 on SunOS 5.7 w/4-24-2001 patch cluster. Like many other users I am seeing the hanging session on logout with background processes. This is a huge problem for me as I centrally manage 50+ machines with rdist across ssh. Instead of just complaining about the problem I thought I would put my CS degree to use and try to track down the problem myself. For starters,

Initially send this mail to user group. then realized this is more apt place. Apologies for posting in both groups... Hi all, We're using openssh version 4.7p on our linux 2.6-22 kernel. We have a Java based GUI that opens a secure shell connection to this linux box. To do something over the connection, the GUI opens a session (some times 3-4 simultaneous sessions) & once done, it will

Hello, I'm trying to setup a chroot for one user on my AIX 5.2 system I have tried with openssh 5.0 (don't know where it comes from) and as it didn't work, I have downloaded and compiled the current version (6.6p1) When I connect, password is checked, chroot is done, sftp subsystem is accepted, but I get disconnected without any error Below is all can say about my config (after

Attached is the very verbose ssh output. Just to be perverse, this time two nodes lost connectivity. The only thing I see is lines saying that the two connections are lost, although being honest I have no idea what everything else means. For reference, 8 ssh cinnections were being made at the same time for a 8x8mpi task. N.B., since the OS I am using does not have rsh, I am currently using the

The 4.6p1 sshd is logging this error during remote commands or file transfers: error: channel 0: chan_read_failed for istate 3 Platform is Solaris 8, 4.6p1 + OpenSSL 0.9.8d. The commands and transfers work correctly, so the error message appears to be spurious. The error message does not appear when processing logins. Otherwise 4.6p1 is running without any apparent problems. This error

We installed openssh 3.1p1 on our Solaris 2.8 machine using gcc 2.95.2. During the installation, we modified ssh_config and sshd_config to enable X11 and agent forwarding.

Hello all, I have made SecurID authentication for OpenSSH 3.6.1p2. This patch was totaly rewritten, so please test it before use. Kbd-int authentication is now integrated into challenge response auth. Privsep is now fully suported. PS: What do you think of selective access to the individual authentications, similar to AllowGroups/DenyGroups or maybe AllowUsers/DenyUsers ? Vaclav Tomec
