similar to: [PATCH] mux: fix memory leak of control path if bind() fails

These patches implement a new mux client request to list the currently opened TCP forwardings. It also removes some todos regarding keeping the list of forwardings in the options up-to-date. Bert Wesarg (6): attach the forwarding type to struct Forward merge local and remote forward lists generate unique ids for forwardings to be used for identification remove closed forwardings from

Hi, At the n2k10 OpenBSD network hackathon, I finally got some time to clean up and rewrite the ssh(1) client multiplexing code. The attached diffs (one for portable OpenSSH, one for OpenBSD) are the result, and they need some testing. The revised multiplexing code uses a better protocol between the master and slave processes and I even bothered to write it up :) It tracks the control sockets

Hi, Ssh -f forks itself in the background. Very usefull if you would like to e.g. tunnel munin over ssh. Now it's tricky to terminate one process if you have multiple running. It seems that ssh currently (looked at 5.1p1) has no write-pid-to-file functionality So I implemented a patch which do so. Tested it a little and it seems to work. Hopefully it is of any use in my form or inspires the

Hi I'm trying to wrap ssh in an application using glib. For now, I'm launching the ssh client in master mode and want it to detach, keeping the control socket around. I figured I could do that using the -f flag and the usual Control* options to force ssh to daemonize (ideally without executing any command), but it turns out that glib doesn't recognize the daemonized process as

(Second try to send this. I wonder if the first one gotten eaten by a spam filter; I'll link to patches instead of attaching them.) Here are the tincctl patches I've been working on. They apply to http://www.tinc-vpn.org/svn/tinc/branches/1.1@1545. I intend to commit them once the crypto stuff's fixed. Since they're basically done, I'm emailing them now for review and in case

OpenSSH 5.6 has just been released. It will be available from the mirrors listed at http://www.openssh.com/ shortly. OpenSSH is a 100% complete SSH protocol version 1.3, 1.5 and 2.0 implementation and includes sftp client and server support. Once again, we would like to thank the OpenSSH community for their continued support of the project, especially those who contributed code or patches,

Hello, I just ran upon this problem and couldn't find it in bugzilla. SSH crashes (abort trap) if all of the following conditions are met: (a) option -f is used (crash happens when going to background), (b) reverse port forwarding is set up (option -R), (c) option ExitOnForwardFailure is enabled, (d) there are no actual port-forwarding failures. The problem can be reproduced by

Hi, I posted this question to the OpenBSD bugs list last week, however I have had no reply and it was suggested on IRC that I post here instead. So I must apologise if this is not appropriate.
