similar to: sshd problem on Solaris 7: Control-C hangs shell

I don't already figure out what is the real impact of this but I think there is a typo in function sigchld_handler() in serverloop.c (l 75). It is written if (WIFEXITED(child_wait_status) || WIFSIGNALED(child_wait_status)) child_terminated = 1; child_has_selected = 0; But I think one actually means: if (WIFEXITED(child_wait_status) || WIFSIGNALED(child_wait_status)) {

Hi, I was looking through the source, and I noticed that the following code appears twice in the file serverloop.c. Is it supposed to, and if not, would there be any ill effect? +289 +290 /* Read and buffer any available stdout data from the program. */ +291 if (!fdout_eof && FD_ISSET(fdout, readset)) { +292 len = read(fdout, buf,

Hello, I believe that there is a bug in OpenSSH that affects its usage on AIX 4.3.3 - Maintenance Level 3 and higher. This bug was introduced by a change by IBM in the "/usr/lib/drivers/ptydd" driver, and it affected IBM's own telnetd daemon (reference

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

When connecting with v1, the server logs a message when I exit my login shell: Closing connection to 130.207.167.32 However, when connecting with v2, it only ever logs: Connection closed by remote host.

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

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

I recently started building a simulator using honeyd as an IP emulator and experienced an issue with hangs on exit from ssh and sftp sessions. A quick look at the OpenSSH source code revealed the following: In serverloop.c there is a signal handler defined for SIGCHLD as follows: static void sigchld_handler(int sig) { int save_errno = errno; debug("Received SIGCHLD.");

We use ssh (RedHat 2.5.2p2-5) heavily in non-interactive mode, for managing servers from central controllers, and transferring applications/ data around networks. Very occasionally we've seen the situation where the ssh client and server are both stuck in select, both selecting on only the tcp socket of the connection, and with no timeout. No children of sshd remain (even as zombies), and it

Hi, We have upgraded the openssh 4.6P1 on Solaris 8 servers. After upgrade we get the below error message whenever we execute the remote commands using ssh.

On 2.3.0p1, we have been experiencing the SSH2 stdout truncation problem that was reported by a few users. I built the 20010115 snapshot. It seems to correct the problem but before I was able to test it, I had to change sigchld_handler2 so it would not reset the signal handler before waitpid is called. On Irix, it seems a SIGCHLD is delivered for ever... I haven't tried the last snapshots so

Thanks for the interesting puzzle to crunch! Looking at these few bread-crumbs, I wager an educated guess that this loops in `sendcmd()` (where CLI child processes talk to a daemonized copy which tracks the timers for events), around here: https://github.com/networkupstools/nut/blob/v2.8.0/clients/upssched.c#L583-L626 for the daemon and here for the child:

Hi all... I''ve just got my hands on a Solaris 10 box for the first time.
