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

The version of sshd in FreeBSD 8.4 is not backward compatible with older version from 8.3.

It will remove any default text appended to SSH protocol banner (for example 'FreeBSD-20120901'). On

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

Hi guys, I have a server setup with openssh-5.0p1 and use some users as sftp-only chroot accounts.

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

Hi Peter, What I am looking for is an SSHD configuration where every successfully authenticated connection also guaranteedly will lead to a ForcedCommand invocation. Currently I understand this to be the case only for the connections that open channel to deliver a terminal, command or SFTP (I don't know if you have a collective name for such non-forwarding channels). Is this possible?

Wonder if you guys could help me out...have a security problem with sshd wich enables a user to do a password login tough the sshd_config states PasswordAuthentication no My config works fine in both gentoo and openbsd 3.3 but users are able to login with tunneled clear text passwords in both 4.9 and 5.1 Im lost.tried everything I can think of. Here is the config:

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

Hi, As I understand the "ForceCommand" in the sshd_confing file is meant to ignore any command supplied by the client, but if user's home is shared by server and client machines over network (ex. NFS) then user can still put something else into ~/.ssh/rc file and overcome this limitation. Is it possible to disable execution of the ~/.ssh/rc file in such a case? Thaks, Mike

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
