similar to: OSF_SIA bug in 2.3.0p1

A while back, I sent in a patch that added Digital Unix SIA authentication to OpenSSH. Well, I just figured out that it didn't handle everything correctly (locked accounts could still log in). I thought I had checked that, but I guess I missed it. Anyway, here is a patch against OpenSSH 2.2.0p1 that fixes this. -- Chris Adams <cmadams at hiwaay.net> Systems and Network Administrator

BSD/OS 4.2 comes with OpenSSH 2.1.1p4, patched to support BSDI's authentication library. However, BSDI's patches have several problems: 1. They don't run the approval phase, so they can allow users to login who aren't supposed to be able to. 2. They don't patch configure to automatically detect the BSDI auth system, so they're not ready to use in a general portable

What do we loose by not having post-auth privsep? What code is executed between authorization and actual setting of the effective uid?

Hello. The following is a patch against OpenSSH 3.0.2p1 to fix OpenSSH's handling of Tru64 SIA authentication. The main changes are to make the SIAENTITY a global variable (so that it remains persistent across function calls), initialization only happens once, the session is only released once. This makes SIA modules that require authentication in order to perform certain actions during the

I have found the following patches to be desirable for using sshd on a Tru64 UNIX system with the Kerberos 5 SIA module (libsia_krb5.so) from Heimdal. These patches do the following: 1) preserve context between the password authentication and the session setup phases. This is necessary because the Heimdal SIA module stores Kerberos context information as mechanism-specific data in

The following are patches against openssh 2.1.1p4 to add support for the BSD_AUTH authentication mechanisms. It allows the use of non-challenge/response style mechanisms (which styles are allowed my be limited by appropriate auth-ssh entries in login.conf). The patches also add support for calling setusercontext for the appropriate class when called with a command (so that the PATH, limits,

Hi all, among other things, we provide shell access to various unix based platforms for our students and university staff. Recently, there has been increasing number of root login attacks on one particular Tru64 machine running OpenSSH. The host is configured with "PermitRootLogin no" but every once in a while SIA auth with TCB enhanced security locks the root account. I suppose

Here is a long-overdue (sorry about that) patch for Tru64. It is pretty minor mostly (minor formatting and removal of a couple of unneeded calls), and it disables post-auth privsep (so that OpenSSH will work "out of the box" on Tru64, avoiding the many questions). I'm also looking at getting setproctitle working. For Tru64 4.x, it isn't a big deal (normal PS_USE_CLOBBER_ARGV

Okay, here is a fixed version of the patch I sent before for fixing the problems I know about with Digital Unix SIA: displaying too much info (MOTD, last login, etc.) when access is denied, and the loss of the error message sometimes when access is denied. It does break some code out of do_login into a couple of separate functions. I did this to avoid duplicating the code in a couple of places.

Either this never made it to the list or no one cares about Tru64. This is the last time I'll send this patch to the list. If no one steps up and finishes it or provides me with enough information to fix any remaining bugs (one being complaint that 'ssh site cmd' does not work right). If there is no activity on this for a week. I'll post it to bugzilla and will ignore any

Ok.. I need wider testing for this. I'm getting reports back it works mostly. 'ssh site ls' fails, but they can login with Privsep enbled. Can I get those who are using Tru64 or OSF/1 that have SIA enabled to test? This should apple to either -cvs or the current snapshot (I would perfer not to use 3.4p1 due to bugs). I'm going on a trip next week and will be around very spotty

This privsepifies OSF/1 SIA, but I'm still being told the same error occurs. I'm stumped. Without an OSF/1 box near me I can't do too much more help unless someone can either tell me what is wrong or show me why SIA is failing in their logs. (And tell me if it's different w/ or w/out this patch) - Ben Index: auth-sia.c

It still is not right, but thanks to Steve we have gotten this far..

Hello, I came across an interoperability problem in OpenSSH 3.0p1 and 3.0.1p1 concerning the AFS token forwarding. That means that the new versions are not able to exchange AFS tokens (and Kerberos TGTs) with older OpenSSH releases (including 2.9p2) and with the old SSH 1.2.2x. In my opinion this problem already existed in Openssh 2.9.9p1, but I have never used this version (I only looked at the

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

Hello, appended is a patch that makes it possible to use PAM both for password authentication and TIS (i.e. s/key or opie or any other interactive challenge/response scheme). I have developed this starting from the patch at http://www.debian.org/Bugs/db/61/61906.html on Debian with openssh-2.1.1p4-3. After configuring ssh with --with-pam-tis, there are two PAM services, "sshd" and

L.S We have a problem compiling the latest ssh (openssh2.1.1p2) on TRU64 Unix 4.0D we got the following error message ... auth1.c:507: `saved_argv' undeclared (first use in this function) .... auth1.c:509: warning: passing arg 4 of `sia_validate_user' discards qualifiers from pointer target type *** Exit 1 where line 509 ===> (sia_validate_user(NULL, saved_argc, saved_argv,

Here is a patch that does TIS auth via PAM. It's controlled by a switch in the sshd_config. You'd use it by having a PAM module that sets PAM_PROMPT_ECHO_ON. eg, you could use it with pam_skey or pam_smxs. The patch is against the 2.9.9p2 distribution. I'm not on the list, a reply if this patch is accepted would be great. (But not required, I know some folks have a distaste for

Hi All. While wandering in auth-pam.c I noticed that there's a few Portable-specific escapees from the xmalloc(foo * bar) cleanup. There's also a "probably can't happen" integer overflow in ssh-rand-helper.c with the memset: num_cmds = 64; - entcmd = xmalloc(num_cmds * sizeof(entropy_cmd_t)); + entcmd = xcalloc(num_cmds, sizeof(entropy_cmd_t));
