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 control master mode. One will succeed in creating the c...

I noticed "make tests" for openssh-5.2p1 fails the multiplex.sh tests. Turns out this is because I happen to have some non-standard configuration options in $HOME/.ssh/config and most of the multiplex.sh tests do not use a "-F $OBJ/ssh_config" option, which means they end up reading the users $HOME/.ssh/config. Is this on purpose or a bug?

Hi all, currently I am considering writing a patch for OpenSSH that will allow portforwarding using the control_master unix domain socket. The idea is to introduce an extra SSHMUX command, SSHMUX_COMMAND_SOCKS, which will then pass control to the normal socks functions used for dynamic forwarding. The main reason for me to write this patch are: - some more control over who gets to connect to

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, all Congratulations for the latest OpenSSH release! Currently I'm writing the cases for testing the new feature. But this new feature is very complex for me: Ssh(1) connection multiplexing now supports remote forwarding with dynamic port allocation and can report the allocated port back to the user: LPORT=`ssh -S muxsocket -R0:localhost:25 -O forward somehost Can you tell me the way

Resending, got blocked last time. I have a few things I'd like to say about the (seriously nifty) connection sharing feature of OpenSSH and I'm not sure if the convention here is to use one email thread per distinct thing or just stuff everything into one email. I decided to combine them because splitting is much easier than combining. Thing 1: This is the main thing that motivated me to
