similar to: [Bug 193] New: sshd: error: select: Bad file number

Yes, this is a patch against an older version of OpenSSH with other stuff anyways, BUT, it's so TRIVIAL(*), that you can see how it would apply to newer versions (which I've not tried). Here's the gist: server_loop2() has a race condition with respect to reception of SIGCHLD and checking/setting child_terminated. This patch does two things: wait_until_can_do_something() adds a 1

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).

Hi :-) i have try a hang on exit patch that i found in the web for an old openssh version, but it dosent help :-( in a german gdb howto i found a tip that the backtrace output can help to analyse the problem.... is it a solaris problem ? Greetings Frank sshd: #0 0xff19d618 in _poll () from /usr/lib/libc.so.1 #1 0xff14d53c in select () from /usr/lib/libc.so.1 #2 0x000339a0 in

Here is my third attempt at the idletimeout patch. I tried to address the points which Marcus Friedl brought up. It is actually bigger than the previous patches, but not as intrusive. It is big because it moves some stuff from serverloop.c to packet.c. - I moved all the logic to packet.c. This means that I also had to move the actual select() call, which used to be in serverloop.c to packet.c.

Can anyone offer any advice on this issue? We've tried patching sshd to have a maximum 10 second timeout when calling select() in serverloop.c, and this doesn't appear to have had any ill effects.

Hi, I am trying to run sftp on SX-6 and it is giving me problem when I try to exit from sftp. On pressing ^D or entering "bye" on sftp prompt, sftp hangs. And I have to press ^C to quit. The versions are: - 1. openssh-3.1p1 on both client and server. 2. Both client (sftp) and server (sshd) are running on SX-6 It appears that the client and server are hanging on "select".

openssh-2.9.9p2 assumes that pid_t, uid_t, gid_t, and mode_t are no wider than int. GCC complains about this assumption on 32-bit Solaris 8 sparc, where these types are 'long', not 'int'. This isn't an actual problem at runtime on this host, as long and int are the same width, but it is a problem on other hosts where pid_t is wider than int. E.g., I've heard that 64-bit

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);

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Greetings, I am not sure if this is the correct place to ask these question, if I am at the wrong place please advise. I am currently working on some modifications to openssh which record the users rsa/dsa identity comment file to a log file when the user logs in (password authentication is disabled). The ssh1 portion of the modification works

Can I get people from other platforms to test the waitpid.patch to see if it solves hang-on-exit on their platform? I can confirm Solaris at this moment (but I've not done heavy testing at this moment) that is works like a charm (Solaris 7). It handles 'sleep 90&' vs 'nohup sleep 90&' correctly (killed, vs left). thanks. - Ben ---------- Forwarded message

Please find enclosed two patches for OpenSSH 3.1p1. The first patch solves a problem where sessions will be left "hanging" when you normally exit from a ssh shell (for example by logging out from the remote host via "exit" or "logout"). The problem seems to be that sshd (and some other parts of OpenSSH) doesn't check the return code and errno from waitpid() for

Is anyone bothered by the compiler warnings that indicate that the format strings don't match the associated variables? I was, so I cast most of the objectionable args (pids, uids, gids) to "long", and added an "l" (el) to the format string. A single item was cast to an int. Here's the patch. If you haven't applied my UseLogin patch, the line numbers in

Hello, In response to the timing analysis attacks presented by Dawn Song et. al. in her paper http://paris.cs.berkeley.edu/~dawnsong/ssh-timing.html we at Silicon Defense developed a patch for openssh to avoid such measures. Timing Analysis Evasion changes were developed by C. Jason Coit and Roel Jonkman of Silicon Defense. These changes cause SSH to send packets unless request not to,
