Hello, I am trying to force a command for all users *except* for users in the "wheel" group. My idea was to do the following in sshd_config: ForceCommand /usr/bin/validate-ssh-command Match Group wheel ForceCommand But obviously this doesn't work, because ForceCommand requires an argument. I couldn't find a way to achieve what I want. I wrote a patch that adds a

This problem can be solved by chowning the rc (and user conf files) files to some other user and chmod'ing the group and other write bits off. I say this because usually, when people use "ForceCommand" the intention is to severely restrict a particular account. Going down this path requires that you do a lot of homework around restricted shells/profiles/etc. and changes you

Hi, sorry if it is the wrong approuch to suggest improvments to OpenSSH, but here comes my suggestion: I recently stumbled upon the scponly shell which in it's chroot:ed form is an ideal solution when you want to share some files with people you trust more or less. The problem is, if you use the scponlyc as shell, port forwarding is still allowed. This can of course be dissallowed in

Hi All First of all apologize for my bad English ? it is not my native language. I'm using ssh for my everyday work. And I have noticed strange behaviour in sshd daemon. In sshd_config file there is option ForceCommand, and if I'm making sftp connection it look like command is also executed, I receive error message and connection is lost. In my opinion ForceCommand should not be

> /usr/sbin/sshd -oForceCommand=internal-sftp > sftp user at host # This connects as expected. > ssh user at host # This hangs...at least from an end-user's perspective. It would be ideal if the connection terminated gracefully. Do others see this same behavior? If so, is there a fix or configuration change that can implemented to eliminate the hang? I'm using OpenSSH

I've hit two roadblocks while using openssh -D as a general proxy: - openssh doesn't have an internal-null, so the options are to either give the user account a real shell and ForceCommand, or set the shell to something like /bin/cat and ChrootDirectory. I don't want proxy-only accounts to have a shell at all. - Comparing mini-httpd SSL/aes256 vs mini-httpd (localhost/no SSL) via

Hallo. If `sshd` is configured to have a ForceCommand, no `ssh ?N` must skip this *forced* server?s setup, isn?t it? But it isn?t so. Thus, admin may think that the command is forced by a server, but user can skip that. In such case only port forwarding is available, but anyway *force* is meaningless, IMHO. -- sed 'sed && sh + olecom = love'? <<? '' -o--=O`C

I would like to implement an arbitrary script to be executed when logging on via SSH. This is supposedly possible using the ForceCommand option to sshd. However, as soon as I implement any script, even as simple as echoing a string, clients can no longer connect to the server. Clients report only that the connection was dropped by the server. The server, in debug mode, shows: Feb 17 16:14:01
