Hi, the attached patch adds support for the keywords "OpenCommand" and "CloseCommand" to ssh_config. They are commands which are executed before the connection is established (or ProxyCommand started) and after the connection has been closed (or ProxyCommand ended). this is usefull for stuff like portknocking or (that's what I wrote the patch for) talking with trapdoor2

Hi, (I'm not subscribed to the list, so please CC me on reply.) I'd like to request adding a feature to OpenSSH: Task: ~~~~~ It is quite sometime useful to invoke a program prior to connecting to an ssh server. The most common use case will probably be port knocking. That is a small program sends certain packets to a server and the server reacts to this by unlocking the ssh port, which

Hello! I'm hoping that Gmail won't HTML format this mail so that I'll get flamed :) Anyway, my question relates to ssh_config. The problem I find is that the Host pattern is only applied to the argument given on the command line, as outlined in the man page: "The host is the hostname argument given on the command line (i.e. the name is not converted to a canonicalized host name

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

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

This is a better approach to persistent control masters than my previous attempt. Instead of forking before we make the connection, do so only when the original session has closed -- much like the code for '~&' backgrounding already does. My earlier patch for 'ControlPath none' still applies and is required, btw. --- openssh/clientloop.c~ 2005-06-17 03:59:35.000000000 +0100

Moin, attached is a patch, which adds a new configuration option "PreferAskpass" to the ssh config. ssh{,-add,-keygen,-agent} will use ssh-askpass to prompt for passwords, if this option is set to "yes", and if ssh-askpass is available. Default for "PreferAskpass" is "no". Pacth is against current CVS. Sebastian -- signature intentionally left blank.

By the way, I noticed in the previous IdentityFile patch I forgot to expand tilde. I fixed this by making the change in ssh.c instead of readconf.c, which is probably where it belongs, as far as the existing code is concerned: diff -ur openssh-3.0.2p1/auth.c openssh-3.0.2p1I/auth.c --- openssh-3.0.2p1/auth.c Sun Nov 11 17:06:07 2001 +++ openssh-3.0.2p1I/auth.c Sun Jan 27 12:05:14 2002 @@ -44,7

Hi, I'm not a subscriber to this list so please CC: me in any replies. I found myself in a situation where I was behind a corporate firewall that allowed only web requests to the outside world (and furthermore those requests had to be via their proxy server). Therefore, I couldn't SSH to the outside world. However, the HTTP proxy 'CONNECT' method, which is normally used to

Here is a patch to allow private key files to be placed system wide (for all users) in a secure (non-NFS) mounted location on systems where home directories are NFS mounted. This is especially important for users who use blank passphrases rather than ssh-agent (a good example of where this is necessary is for tunnelling lpd through ssh on systems that run lpd as user lp). IdentityFile now accepts

Here is the user-dependent IdentityFile patch for openssh3.5 (BSD version), which allows private key files to be placed system wide (for all users) in a secure (non-NFS) mounted location. This addresses an important security hole on systems where home directories are NFS mounted, particularly if there are users who use blank passphrases (or when lpd is tunneled through ssh on systems running lpd

Hi, Not sure if this anyone else is interested in this but to me it seems to make sense to use different control session multiplexer sockets for bulk and interactive workloads.

Attached (and inline) is a patch to add the following config options: ControlBindMask ControlAllowUsers ControlAllowGroups ControlDenyUsers ControlDenyGroups It pulls the peer credential check from client_process_control() in ssh.c, and expounds upon it in a new function, client_control_grant(). Supplemental groups are not checked in this patch. I didn't feel comfortable taking a shot

Hi all, This is a client side only implementation of reversed dynamic (SOCKS) TCP forwarding, which means it is compatible with any existing servers have 'remote forward' capability. To establish such forward, use "ssh -R [BIND_ADDRESS:]PORT ...". The server will listen on that port and address and accept SOCKS traffics. Hope this will be useful for you. There was an

There is a race in the setup of the ControlMaster socket in auto mode, as illustrated by the following command line: ssh -oControlMaster=auto -oControlPath=sock localhost 'sleep 1; echo 1' & ssh -oControlMaster=auto -oControlPath=sock localhost 'sleep 2; echo 2' & Both of the commands will try to start up as a control client, find that sock does not exist, and switch into

In the current implementation, ssh always uses the hostname supplied by the user directly for the SSHFP DNS record lookup. This causes problems when using the domain search path, e.g. I have "search example.com" in my resolv.conf and then do a "ssh host", I will connect to host.example.com, but ssh will query the DNS for an SSHFP record of "host.", not
