similar to: FW: ibuf_empty delayed efd

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

Thank you for the reply. I changed the remote command to a generic example because in our case, we are using an internal binary that I didn't want to make public. I thought it wouldn't matter, but apparently, it does. I am sorry I can't share more about this tool. BTW, our environment is based on FreeBSD, not on Linux. In our case, because "isatty" is set to 0, it never

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

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

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

Hi, We recently upgraded OpenSSH from 7.5p1 to 8.0p1, and received a report that there was a behavioral differences where the ssh session did not disconnect after a remote background command execution. For example, "ssh user at example.com 'tail -f /var/xxx &' After looking at the debug logs and comparing the code, it seems there was a bug in the portable version during the

Hi, At the n2k10 OpenBSD network hackathon, I finally got some time to clean up and rewrite the ssh(1) client multiplexing code. The attached diffs (one for portable OpenSSH, one for OpenBSD) are the result, and they need some testing. The revised multiplexing code uses a better protocol between the master and slave processes and I even bothered to write it up :) It tracks the control sockets

Greetings, I have a problem with OpenSSH -current and SCO 3.2v4.2, when I execute a remote command or exit from a session, the connection hangs, ( line 326 of serverloop.c). This problem only exists when using ssh2. server side debug (-d -d -d ): debug1: Received SIGCHLD. debug2: channel 0: read failed debug2: channel 0: close_read debug2: channel 0: input open -> drain debug2: channel 0:

Hello, The error message in the subject line occurs with the new 2.3.0 openssh version and appeared in the previous snapshots on our Solaris systems. As far as I remember it was reported, but have not seen any more about this. I have looked into it a little bit. First, the file session.c (line 1849 onwards): debug("session_exit_message: release channel %d", s->chanid);

When I encounter the problem with TCP port forwarding locking up, I'll see this on the client window (if I haven't invoked ssh with -q): chan_shutdown_read failed for #1/fd6: Transport endpoint is not connected chan_shutdown_read failed for #1/fd6: Transport endpoint is not connected This is with Blowfish encryption. I have to kill and restart the client when this happens. Phil

The Linux implementation of TCP sockets has a bug which causes shutdown(sock, SHUT_RD) to fail spuriously (ENOTCONN) if the write side of the socket has already been shut down. If you are using SSH port forwarding to tunnel HTTP through a firewall, nchan.c will tickle this bug once for every HTTP exchange. You will therefore get lots of useless, annoying error messages: channel 2:

Hi! I have problems with connections being left open with both 2.2.0p1 and the latest snapshot when using agent-forwarding. (I didn't use this with older versions, so I don't know whether this problem is older.) Scenario: I have a secret key that I run with ssh-agent on host "host-A". I then connect to "host-B" using 'slogin -A host-B'. When executing a

As of Sunday evening, OpenSSH has an interactive sftp client. It should be in the more recent snapshots. It would be appreciated if you could test new client and find all the bugs :) Please also have a read of the manpage and ensure that it matches what is implemented. I am working on fixing the ones that I know about, so please try to stay up to date with the snapshots. Thanks, Damien

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,

I have been using OpenSSH for a while, and I would like to thank you for the great package. Here is a report of mysterious warning message lines, I get while I use OpenSSH. They don't seem to be serious, but annoying nevertheless. version: openssh-1.2.1pre27 OS Linux standard 2.2.14 #18 SMP Thu Jan 6 06:07:45 JST 2000 i586 unknown (compiled with gcc 2.95.2) Compiler gcc -v Reading

I'm looking at the code from CVS as of May 21. The statement to allocate the mux state is allocating the size of a pointer, instead of the size of the struct being pointed to. The bug is benign in the original code because the struct has only an int element inside it, but it would corrupt memory if the struct were to be extended. Simple fix here: diff --git a/mux.c b/mux.c index
