similar to: How disable forwarding-only connections (i.e. non-shell/command non-sftp connections)? (Maybe this is a feature request!)

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?

Hello List. ? i?m trying to setup a limited SSH server with SFTP. The requirements: -????????? There are users to whom only SFTP should be available. (sftp-only group) -????????? There are users to whom SFTP and shell access should be available (admin group) -????????? SFTP clients have to authenticate with username and password -????????? shell users have to authenticate with private key.

I've configured OpenSSH_5.3p1 to only allow sftp connections (openssh chroot functionality). i.e. Subsystem sftp internal-sftp Match group sftpusers ChrootDirectory /chroot/%u X11Forwarding no AllowTcpForwarding no ForceCommand internal-sftp So far everything works correctly with sftp but when a user ssh's or scp's to the box the login

Some OS distributions (FreeBSD, RHEL / CentOS, probably Fedora) have X11Forwarding enabled by default. DES --

Hi! I want to set a OpenSSH server which restricts some users to only chrooted SFTP, while others have full/normal ssh, scp and sftp access. Most or all guides on the web say that I should enable the config line "Subsytem sftp internal-sftp" among other things, but I've found out that this only causes non-restricted users to not be able use SFTP at all, only the chrooted users.

Thanks for these 3rd party hacks! I don't trust them. There must be such feature in openssh out of box. So the most secure/easyer method of giving sftp access to porn collection is: Damiens sftp-server chroot patch, which I hope to see in openssh one day :) http://marc.info/?l=openssh-unix-dev&m=116043792120525&w=2 # useradd -d /data/p0rn -m share /etc/ssh/sshd_config: Match user

Hi, I configured openssh 5.1p1 for sftp server. Here the specifications in sshd_config file: Subsystem sftp internal-sftp Match Group sftp ForceCommand internal-sftp ChrootDirectory /home/%u AllowTcpForwarding no When a user is logged in, he can't upload his document and he receives this message: carlo at Music:~$ sftp user at 213.217.147.123 Connecting to

I am supporting a site that allows members to upload release files. I have inherited this site which was previously existing. The goal is to allow members to file transfer to and from their project area for release distribution but not to allow general shell access and not to allow access to other parts of the system. Currently rsync and old scp has been restricted using a restricted shell

I'd like to have sshd write entries into the systemd journal logging sftp transfers. From googling, it seems that one needs to edit /etc/ssh/sshd_config adding this line: Subsystem sftp /usr/lib/ssh/sftp-server -f AUTH -l VERBOSE I can transfer files via filezilla (sftp) but I don't get anything in `journalctl -u sshd` that shows these transfers, just a few lines showing I connected.

Maybe I am not testing the signin correctly. Here is what I am doing. I sign into the client/workstation (hereafter referred to as C/W) via ssh as the local "admin" from another C/W so I can open many terminals to tail log files. Then "sudo -i" into "root". All testing is run as "root". When I sign into "root", I see this: > admin at lws4:~$

Hi, I've posted this question on ServerFault, but no answer has been found (http://serverfault.com/questions/431329/user-cant-sftp-after-chroot). I have version 1:5.3p1-3ubuntu7 To sum up: I want to chroot the user sam. Things I have done: - add user 'sam' to group 'users' - added Subsystem sftp internal-sftp to /etc/ssh/sshd_config (at the bottom) - added a Match : -- Match

Hi OpenSSH devs, I?m wondering if the following has any merit and can be done securely ... If you could match on principals in the sshd_config, then (for example) on a gateway machine, you could have something like /etc/ssh/authorized_keys/sshfwd: cert-authority,principals=?batcha-fwd,batchb-fwd? ... /etc/ssh/sshd_config containing: Match User sshfwd PubkeyAuthentication yes

for the A nat B C connect back to A using -R 2222:localhost:22 pattern, (see diagram at https://github.com/daradib/sidedoor) I want to limit B's user to just what is needed to do the port forward. I am hoping this is documented, but I can't find much more than "you should future out how to secre it." I setup an ansible playbook to instal and configure sidedoor on A. I have
