similar to: [Bug 524] Keyboard-interactive PAM back end hides information

The following patch (relative to -current) makes PAM a proper kbd-interactive citizen. There are a few limitations (grep for todo), but the code seems to work OK for protocols 1 & 2 with and without privsep. Please have a play! auth2-pam.c is based on code from FreeBSD. Index: auth2-chall.c =================================================================== RCS file:

Below is a new PAM kbd-int diff based on FreeBSD's code. This code makes PAM kbd-int work with privilege separation. Contrary to what I have previously stated - it *does* handle multiple prompts. What it does not handle is multiple passes through the PAM conversation function, which would be required for expired password changing. I would really appreciate some additional eyes over the

The following is a patch (based on FreeBSD code) which gets kbd-int working with privsep. It moves the kbd-int PAM conversation to a child process and communicates with it over a socket. The patch has a limitation: it does not handle multiple prompts - I have no idea how common these are in real-life. Furthermore it is not well tested at all (despite my many requests on openssh-unix-dev@). -d

If the info_response code is going to test that the # of responses is < 100, then the info_request code should check that < 100 prompts are sent. It would be rude to send 101 prompts and then fail when the responses come back. I actually think the test should be removed altogether, the limit seems quite arbitrary, but here is a patch to not send > 100 prompts. With this patch, the test

Hi ! Here's an experimental patch for openssh-2.1.1p4 to add support (to openssh client) for -R (protocol 2). So if you have access to a commercial ssh2 server (that allows port forwardings) could you test this patch. (Note the openssh server doesn't have support for -R with protocol 2 so testing with openssh server won't do much good). To test remember to use -o "Protocol

Hi all, I've recently tried rsync in daemon mode on AIX. Unfortunately, after handling connections, the daemon segfaulted. I've located this problem to the signal handler for SIGCHLD in socket.c - it seems reinstalling the signal handler before doing waitpid caused the signal to be redelivered, so the program recurses to the signal handler before it runs out of stack space in the end and

Hi ! Here's a patch to add remote port forwarding support (protocol 2) for openssh. I have tried to test that it works like it should but a more thorough testing is needed. This patch adds both client/server support. The patch should be applied to openssh-2.1.1p4 source tree. Also included is a PortForwarding sshd_config option, new ./configure option --disable-forwarding that should make it

Hi all, I'm very new in this list, as looking for codes to plug up the lack of functionality of "Protocol 2 Remote Forwardig". Fortunately, I could find it in MARC's archive. Mr. Jarno Huuskonen posted the codes in Sept, last year, and I tried applying it to my FreeBSD box environment. I couldn't apply an original patch, of course, for incompatibility of virsion. The

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
