The primary purpose of the attached patches is for portable OpenSSH to support changing expired passwords as specified in shadow password files. To support that, I did a couple enhancements to the base OpenBSD OpenSSH code. They are: 1. Consolidated the handling of "forced_command" into a do_exec() function in session.c. These were being handled inconsistently and allocated

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

With OpenSSH 2.9.9p2 as the server, I'm not able to do scp or "ssh machinename command" in general to any of my Suns! I tracked this down a bit; the problem occurs only when PAM support is enabled. However, if I remove line 430 of session.c, "do_pam_session(s->pw->pw_name, NULL);" inside of do_exec_no_pty, the problem goes away. It looks like the following entry

On Solaris, the pam_unix module includes a pam_session which updates the lastlog file. Since OpenSSH calls pam_session before reading the lastlog file, SSH logins to systems with this configuration (as well as similar ones, I'd imagine) report the last login time and remote host as the values from the current session. My solution to this problem is to call pam_open_session in the child,

Hello, all- Apparently, under Solaris (I can personally confirm SunOS 5.7 and 5.8), pam_open_session will generate a segfault if PAM_TTY is not set. The obvious symptom of this is that OpenSSH 2.9.9p2 will segfault on any operation that does not request a tty (do_exec_no_pty). Based on a quick google search, this seems to have been encountered by others, though the specific symptoms seem to

The short version: There's a "#define USE_PIPES" in the middle of session.c; it would be better if it were in (e.g.) defines.h or some other .h file. (If in fact it needs to be defined at all; I'm not convinced that it does.) Here's the (much) longer version: I recently installed the latest OpenSSH on some of our servers (RHEL5, which provides the 4.3 release) and soon

Hello, By the 26th of May I will have been waiting for response for 17 days.

All line number are approximate, but most likely w/in 10 lines of the OpenSSH 1.2.3 tarball. I unpacked the tarball, and did a ./configure;make;make install and now I've had some problems. :-) OK, I've tracked down lots of goofy stuff w/ slack7 and OpenSSH I've got a couple of questions. What is /dev/tty and why does ssh try to open it to read the password instead of stdin?(this cause

I was testing the Linux port of 2.1.0p2 and noticed that the F-Secure SSH client for Windows 4.0 couldn't successfully connect using its secure file-transfer facility. The server log reported that authentication was successful, then the log left off with a semi-cryptic "subsystem request for sftp" line. After that, nothing. Poking around the source, I found this little routine in

I found this problem on 32-bit Solaris 8 sparc. session.c uses two void functions without declaring them first; this violates the C standard, which requires declarations for such functions. Here's a patch. 2001-09-28 Paul Eggert <eggert at twinsun.com> * session.c (do_pre_login, record_utmp_only): Add missing declarations.

Hi, I met some difficult in reading ssh/sshd souce code, I want to find out how the command that user input in client is executed on the server. I only found out the process_input function put the command in a buffer,but can not find how it is executed. Could you please help me on that? Thank you very much. B Rgds, Kexin

Hi All, I was assigned a project to port the openssh 5.4p1 to Windows.? There has been discussion about Cygwin and SUA on Windows, but the conclusion is to avoid a unix layer.? So came the project.? I was being assigned not because I am familir with openssh, but because I am a Windows application developer.? BTW, the objective is to have a windows sshd daemon, no client is needed at this stage.

Hi. I am running sshd under supervise, using the -e option to capture the logs on stderr. I am trying to do the same for the sftp subsystem, but I have been unable to do so. Using the same -e option to sftp-server simply sends the debug messages to the client's stderr (instead of sshd's stderr) which doesn't help. Is there any way to do this? I am not averse to doing a local

Hi All, I finally got around to trying to test the 7.7p1 release on the HPE NonStop Platform. 7.6p1 worked just fine - no issues at all.

Now that the list is said to be open again, I'm resending this.

The recent patch posted by Steve VanDevender <stevev at darkwing.uoregon.edu> for fixing the session code on Tru64 isn't quite right -- it still fails in the case of NO tty being allocated. The problem is that s->tty is a char[TTYSZ] rather than a char *, and hence can't hold a NULL. Calling sia_ses_init() with the tty being an empty string doesn't signify no tty, and
