similar to: istate / ostate error?

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:

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

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

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

I'm logging in from an irix machine to a linux machine (both running openssh-2.5.1p2) and am unable to run any X applications. I ran a verbose session and this happens: debug: fd 6 IS O_NONBLOCK debug: channel 0: new [X11 connection from host port 4572] debug: X11 connection uses different authentication protocol. debug: X11 rejected 0 i1/o16 debug: channel 0: read failed debug: channel 0:

The command "ssh ls -l /doesnotexist" gives various responses: Running from a 200 MHz PentiumPro with dsa key added to ssh-agent: Mistakes worst to fast machine: To a faster 600 MHz dual processor i686 600 MHz machine: ls: /doesnotexist: No such file or directory -- correct nothing at all -- wrong ls: select: Bad file descriptor -- wrong

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

Markus, How's this patch? - a chan_wont_read()/chan_wont_write() API is added that is very much like chan_read_failed()/chan_write_failed(), but for the debug messages and chan_wont_*() don't ever call error() The 3.0.2p1 channel_pre_x11_open() uses chan_*_failed() but looks like it ought to use chan_wont_*() instead :) - forkoff() no longer fakes EOF for SSHv2 (still

As you are now probably aware, the portability team for openssh still has not fixed the hang-on-exit bug in the 2.9.9p2 release. Attached is a patch for 2.9.9p2 that fixes the hang-on-exit bug for Linux systems. It also adds a useful exit delay feature that has also not yet been incorporated into the main sources. For more information, see the SNFS (secure NFS) web page:

Hi, we are using OpenSSH_2.3.0p1. When using non-interactive mode, sometimes lines are swallowed from standard output: root at hydra:~ # ssh anderson "ls -l /usr/sbin/sshd" -rwxr-xr-x 1 root root 612344 Nov 25 20:26 /usr/sbin/sshd root at hydra:~ # ssh anderson "ls -l /usr/sbin/sshd" root at hydra:~ # ssh anderson "ls -l /usr/sbin/sshd" -rwxr-xr-x 1

Hallo all! I've found a repeatable problem concerning openssh 2.3.0p1 running on a Linux-box with kernel 2.2.17. I compiled ssh from sources with pam-support. Let me describe what I'm doing: rsync -e ssh --delete --exclude "/Daten/test*" --exclude /Daten/anonymous --exclude /Daten/comp_logs --exclude /Daten/ehemalige_rwgsysm/cache --exclude

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

The hang-on-exit bug still hasn't been fixed in OpenSSH-3.0p1... :-( Here again is the patch to fix this bug under Linux, updated for OpenSSH-3.0p1. This has been exhaustively tested for six months now. It also add an exit delay option that can be useful. The patch does not lead to data loss under Linux. Please see the Secure NFS page (SNFS) for further details:

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);

Ok... This could be cockpit error, but I just don't see it. I've installed OpenSSH 2.1.0 and I can't get X11 forwarding to work. I don't recall having this problem under 1.2.3, but I don't use X11 forwarding often enough to really say that I actually saw it work either. Both sides are running OpenSSH-2.1.0-1 installed from rpm. The client side is running RedHat Linux 6.1

I'm using OpenSSH-2.9.9p2 on Solaris 8 sparc64. 2.9p2 worked fine, but 2.9.9p2+ is giving me trouble with one thing - sshd segfaults if I try to connect and execute a command, such as "ssh machine ls". Otherwise it works great. sshd will fork, and the child process segfaults. CVS snapshot does the same thing. I've narrowed this down somewhat. It will only happen if you use
