openssh + pam errors (fwd)
heres a fix for pam support im openssh, inline and attached.. openssh calls do_pam_session early, before a fork(). it does this on the proc still running as root, so it checks the users limits, against what root has running, and depending on limits can fail at the fork() (and almost always does). this patch moves it past the fork. ive been running it for a couple of weeks and everythi...

HP-UX PAM with Trusted System patch
...irly new to the list and new to submitting patches. Can someone please verify the attached patch for running a HP-UX Trusted System with PAM and OpenSSH 3.4p1? The problem seemed to be that pam couldn't verify the user via __pamh after the call to permanently_set_uid in session.c. So I called do_pam_session prior to the call and added a function do_pam_set_tty in order to set the tty after allocation. -- Dan Wanek -------------- next part -------------- diff -u -r openssh-3.4p1/auth-pam.c openssh-3.4p1-dw/auth-pam.c --- openssh-3.4p1/auth-pam.c Tue May 7 21:27:56 2002 +++ openssh-3.4p1-dw/auth-pam....

[Bug 354] New: sshd with privsep doesn't do pam session setup properly
...002) setrlimit, through the pam session setup, isn't called in the appropriate place to allow specified users to have higher ulimits than the server is started with. This ought to work, as pam limits are allowed to specify arbitrarily high limits for users listed. The problem appears to be that do_pam_session is being called after we drop to the user's uid. Without privsep turned on, this all work, as we drop to the user's uid after do_pam_session. Specifically: with privsep on, do_setusercontext in privsep_postauth (sshd.c) is called before do_pam_session in do_exec_pty (session.c). Without pri...

3.7.1p1 appears to break pam session.
Hi, I am running FreeBSD 4.7 and openssh 3.7.1p1. I have enabled PAM usage and indeed, I can use PAM for authentication purposes. Since configure does login_cap.h, the preprocessor is side stepping do_pam_session() altogether in session.c:do_setusercontext(). Here is my patch for session.c. My understanding about portability issues is rather limited. I would very much appreciate if you guys could check this and verify that I am not introducing more problems with this. So far this works for me. --- ses...

ssh and pam-script
Hello I've got a problem with pam-script and ssh. pam-script is a module for PAM that enables execution of given script while pam session opens and/or closes. I try to use it with ssh while logging in and out: it is kind of login and logout scripts. PAM session creation is done in function do_pam_session which is invoked by do_setusercontext which is invoked by do_child. do_child function is invoked after fork. In a child process do_pam_session function sets global variable sshpam_session_open to remember that session was opened. After execution of do_setusercontext and do_pam_session function do_c...

2.9.9p2 bug in PAM support
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 in the Changelog may be responsible: 20010627 - (djm) Reintroduce pam_session call for non-pty sessions. Let me know if you need any additional info to track this down. Thank...

[PATCH] Make PAM chauthtok_conv function into tty_conv
Hi All. Attached is a patch that converts pam_chauthtok_conv into a generic pam_tty_conv, which is used rather than null_conv for do_pam_session. This allows, for example, display of messages from PAM session modules. The accumulation of PAM messages into loginmsg won't help until there is a way to collect loginmsg from the monitor (see, eg, the patches for bug #463). This is because the authentication is postponed and the messages...

Anyway, I have encountered the following compile time problems for openssh-1.2pre15 / Solaris 2.6 / gcc 2.8.1 - * daemon code (bsd-daemon.[ch]) exists but is not linked in. Also, header is not included. Same might apply to bsd-login. * rsa.h needs __P() define to work

[Bug 87] New: Last logon that gets reported upon login is the current login time
...mindrot.org ReportedBy: wknox at mitre.org The last login time that gets reported with a Solaris PAM enabled build of OpenSSH 3.0.2p1 is the login time of the current session. Examining the mail archive, this was reported by Benn Oshrin on 10/12/2001, and he sent in a patch that moved the do_pam_session call into the do_login function in session.c. I can't find any discussion about why that patch did not get applied, but it hasn't, so I propose, instead of moving the do_pam_session call, to move the call to get_last_login_time into do_exec_pty and pass the resultant information to do_login...

a patch for 3.4, please
Hello all, I'd greatly appreciate a patch that will stop PAM mucking around after I log in with a Kerberos 4 ticket and forward an AFS ticket (KTH Kerberos 1.1.1 used for libkrb/libkafs). The trouble is, I need pam_krb4, so that folks, who log in with without tickets using tunnelled plaintext password, would get Kerberos 4 tickets for the box. I rebuilt sshd without PAM in order to verify
