...to enforce one more layer of authentication. For that I need terminal ID in close_session() and pam_sm_setcred() function in PAM module while OpenSSH hardcoded it "ssh". I made few changes in OpenSSh code so it can set terminal ID properly. These changes were : added do_pam_set_tty() in session_pty_req(Session *s) function in session.c and added do_pam_set_tty() in mm_pty_allocate() function in monitor_wrap.c It works fine for root and I get appropriate tty in pam_sm_cred() and pam_sm_close_session() function. But using same code, when I try to ssh through a non root account I am getting tty in...

I do not often use X11 - but when I do I prefer to enable X11forwarding, and when finished - turn it off. This is preferable, imho, to having "clear" X11 processing when local - and otherwise impossible when working remote. Working with openssh-7.5p2 I cannot figure out what (extra) I need to do with sshd_config to get it working. I know that there is a security-fix starting with

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

Could anyone point me to some information on why in HP-UX do_setusercontext() is called after log_getlastlog() and session_pty_req() but before on other things? It is making my chroot patch not behave correctly and I'd like to fix that. -James

I've been trying to get a working version of openssh-3.7.1p2 as well. Unfortunately, afs support has been pulled, and the patch posted on the openafs list coredumps when I compile it. The new way that pam is done also introduces errors since pam_authenticate is supposedly called in a seperate thread so that the correct environmental variables are not passed. Even after applying some changes
