similar to: [PATCH] fix %n expansion in LocalCommand

This provides a mechanism to attach arbitrary configure options into the ssh_config file and use them from the LocalCommand and ProxyCommand. Examples: # set FOO to foo LocalEnvMod FOO = foo # append bar to FOO with default separator "," LocalEnvMod FOO += bar # unset FOO LocalEnvMod FOO = # append foo to BAR with separator ":", if BAR is empty

I've been testing tunneling on Linux with openssh-SNAP-20060116.tar.gz and found a problem. When I use LocalCommand for doing ifconfig stuff, the command line was executed before a tunneling interface is opened. This causes errors on Linux and the interface is not automatically set up. This is not a problem on *BSD because you can do ifconfig for unopened tun/tap interfaces. But in Linux,

To provide a bit more backwards-compatible (which is nice for eg. NFS- shared /home directories) try a few version-number based names. Eg., for "OpenSSH_7.3" the strings that are tried after "~/.ssh/config" are "_7.3", "_7", and "". --- ssh.c | 37 ++++++++++++++++++++++++++++++------- 1 file changed, 30 insertions(+), 7 deletions(-) diff --git

Numerous how-tos all over the Internet show how one would set up a tunnel using ssh, e.g.: ssh -f -o Tunnel=ethernet <server_ip> true I was wondering if there's a way to subsequently acquire the names of the local and remote tun/tap interfaces (e.g., using the default "-w any:any") for subsequent automatic tunnel configuration, e.g.: ip link set $TapDev up ip link set

The attached patch for 4.6p1 adds a feature (-u) that will check to see if a key exists on a remote host. I use this for auditing my users transition to v2 keys very useful. If there is any interest I'll provide a patch for v2 ssh keys also. http://vapid.dhs.org/dokuwiki/doku.php?id=vapidlabs:openssh_check_key_patch -- Thanks Larry --- orig/openssh-4.6p1/sshconnect1.c 2006-11-07

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.

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

Hi It seems like a nice idea to expand a %h in the HostName field in ssh_config to the host given as argument to ssh. often one would have a entry in their ssh_config like: camel* User ... It's okay if the system knows that the host camel01 fx points to the right host. But what if the actual host is camel01.daimi.au.dk this is something you wouldn't like to write in your terminal.

From: Christian Hesse <mail at eworm.de> Modern Linux systems create a private directory in /run/user/ for each user, named by user id. This adds a new character sequence '%i' for expansion in ControlPath to match thisi directory.

OpenSSH 7.1p2 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 2.0 implementation and includes sftp client and server support. OpenSSH also includes transitional support for the legacy SSH 1.3 and 1.5 protocols that may be enabled at compile-time. Once again, we would like to thank the OpenSSH

This adds micro-benchmarks useful for tuning virtio ring layouts. Three layouts are currently implemented: - virtio 0.9 compatible one - an experimental extension bypassing the ring index, polling ring itself instead - an experimental extension bypassing avail and used ring completely Typical use: sh run-on-all.sh perf stat -r 10 --log-fd 1 -- ./ring It doesn't depend on the kernel

ssh client has the ability to set the destination of debug logs via the `-E` flag. ssh_config lacks an equivalent keyword to set the same option via configs. This patch follows the same semantics of other `*Path` type keywords and creates a new ssh_config keyword `LogPath`. [0] Bugzilla: https://bugzilla.mindrot.org/show_bug.cgi?id=3683 [1] GitHub PR:

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

I've run into a couple cases where it would be nice to use LocalCommand to run something to setup a session in some way when using ControlMaster. For example, to scp something or do an sshfs mount automatically once your session is established using the control socket. However, in 4.7, LocalCommand is run before ssh_control_listener. It's not terribly hard to work around (fork and

Hi, looking at the code %h and %n expand to the same value. But shouldn't %h expand to options.hostname? Also I think that the host name provided on the command line is always lost because of the line 698 in ssh.c (thats from 5.6p1). Do I miss read something here? Bert
