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 succ...

...uot; SFTP server will drop sftp sessions initiated from the OpenSSH 5.1p (HP-UX) sftp if it receives the "no-more-sessions at openssh.com" flag. It can be reproduced also with the sftp sessions initiated from a OpenSSH 5.1p sftp on a Linux machine. As a workaround we are using now "-oControlMaster=yes" for each sftp connection in order to disable the sending of "no-more-sessions at openssh.com" flag. Can you please add for future versions in "compat.c" that for connections to servers who identify themselves as "XFB.Gateway Unix" a flag should be set that...

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
