similar to: pam protocol 1 fix

I am writing to report a bug in openssh-2.3.0p1, and to suggest a fix. I have OpenSSH installed on a Solaris 8 box. The output of uname -a is: > SunOS dipper.csi.cam.ac.uk 5.8 Generic_108528-06 sun4u sparc SUNW,Ultra-5_10 OpenSSH was configured with the following options: > ./configure --prefix=/jackdaw --with-default-path=/jackdaw/bin:/usr/bin On this OS, with this configuration, it

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

Hi, We've encountered a bug with OpenSSH 3.8.1p1 on Linux. With an account that has an empty password and with PAM and Privilege Separation turned on through the SSH1 protocol, the login fails with: fatal: mm_request_receive_expect: read: rtype 24 != type 46 I believe the problem is a missing do_pam_account() call. The patch below to auth1.c fixes the problem. If this is correct, can

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

Dear list, since the order of authentication and AFS token/KRB TGT forwarding changed (around 3.0), we have had problems with users accidentally overwriting their credentials from a "password" login with forwarded credentials. E.g. user A logs in as user B, but stays with the AFS permissions of user A. A workaround is to use "-k" on these sessions, but "it worked without

http://bugzilla.mindrot.org/show_bug.cgi?id=192 ------- Additional Comments From mouring at eviladmin.org 2002-03-28 04:04 ------- If I understand the PAM code (none of the PRIVSEP code has been made to work with it right now) one should never called auth_password() they should be calling auth_pam_password().. So in mm_answer_authpassword() function it should look something like this

For every (successful) ssh-connection we got an additional annoying entry in /var/log/messages like the following: Jun 19 09:06:57 LIN3135 pam_afs[5913]: AFS Won't use illegal password for user usenbinz The OpenAFS PAM module posts this message when it is called for authentication with an (disallowed) empty password. The simple patch below checks PermitEmptyPasswords in sshd_config before

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, the following patch fixes a potential security hole in the Cygwin version of sshd. If you're logging in to a Cygwin sshd with version 2 protocol using an arbitrary user name which is not in /etc/passwd, the forked sshd which is handling this connection crashes with a segmentation violation. The client side encounters an immediate disconnect ("Connection reset by peer").

Hi, the following patch removes some of the Cygwin specific code from OpenSSH. Since Cygwin is able to change the user context on NT/W2K even without a password since the new Cygwin version 1.3.2, there's no need anymore to allow changing the user context only if the sshd user is the same user as the one which logs in or when a password is given. For that reason the whole function

Precedence: bulk Hi folks, It seemed to me that it would be useful to be able to control access to my server with the /etc/ssh_known_hosts file, using RSA authentication of the remote host. But the protocol only allows RSA host authentication in conjunction with rhosts, while I prefer RSA user authentication. I've made a patch to the server which adds a new configuration option:

Hi, SSH brute force attacks seem to enjoy increasing popularity. Call me an optimist or a misrouted kind of contributer to the community, but on our company server I actually go through the logs and report extreme cases to the providers of the originating IP's. With the increasing number of these attacks, however, I have now decided that it's better to move the SSHd to a different

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

Is anyone maintaining the OSF_SIA support in openssh?

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

Hi All. Attached is a patch against OpenBSD, based in part on the owl-always-auth patch. The idea is that the only way out of auth_passwd for the failure case is the "return 0" at the bottom. I don't know if this is a good way to do it or not, it's presented for discussion. Also, I don't think 3.6.1p2 is quite right WRT these timing issues (eg, you get a fast failure

Hi All, I've been poking around various parts of the auth code for a while. Some platforms support failed login counters and it occurs to me that there's as few too many instances of: #ifdef [PLATFORM] if (authenticated == 0 && strcmp(method, "password") == 0) some_login_failure_func(); #endif The attached patch creates a record_failed_login() function in

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
