Hope ya'all can help! Been reading and reading, and adjusting... to no avail. We need to have chroot'd SFTP activities logged on a file server and for whatever reason, I simply cannot get it to log with users that are chroot'd (this is necessary for auditing and HIPAA - so it is pretty important) I have tried with Fedora 11/12 and even an older Fedora 8 server, the same results: 1.

Maybe one of you can help. We have set up a CentOS server so that each user who logs in via sftp will be jailed in their home directory. Here's the relevant sshd_config: # override default of no subsystems Subsystem sftp internal-sftp -f LOCAL2 -l INFO Match Group sftponly ChrootDirectory /home/%u ForceCommand internal-sftp This actually works great, but none of

I run a sshd host solely to allow employees to tunnel secure connections to our internal hosts. Some of which do not support encrypted protocols.

Hi there, let me just ask if you know some good way to set up user chrooting in such a way, that each sftp user has its chroot directory entry somewhere (whatever path) and gets chrooted there upon its login? Maybe such feature is planned? Thanks... K.

Currently, sshd requires the chroot directory to be owned by root. This makes it impossible to chroot users into their own home directory, which would be convenient for sftp-only users. Is there a particular reason why, in safely_chroot() in session.c, if (st.st_uid != 0 || (st.st_mode & 022) != 0) fatal("bad ownership or modes for chroot "

Dear developers, I need the feature of separately jailed, user writeable and user owned home dirs very badly because I have an SFTP server with 500 users who are partly nested could you please add a feature to set non root chroots with the %h option ? Otherwise I have to rewrite the chroot patch for 4.7p1 :-( thank you very much in advance Dirk

Under "ChrootDirectory" there is a line that says, "This path, and all its components, must be root-owned directories that are not writable by any other user or group." When I first read this "all its components" seemed to mean that all directories and files within this directory must be root owned and root only writable. This seemed odd as I would not be able to

I see that there is a new sshd_config in the latest updates. Since I have altered the original file, this one got installed as .rpmnew It has two changes: > #AddressFamily any So does this make it default to IPv4 only? > #ChrootDirectory none Chroot is now an option for SSH?

Hello, I'm aware of the fact that ChrootDirectory requires that the target directory is root-owned, and I think I've mostly understood why that is necessary, at least within the context of someone who has full shell access. However, I am wondering if that possibility for privilege escalation still exists with a configuration like this: Match Group sftp ForceCommand internal-sftp

Hi, This is either a query or a feature request. I have a system where sftp users are chrooted using scponly, which while requiring much more setup than OpenSSH's internal-sftp method, has the useful feature of allowing an initial chroot to a subdirectory, typically the one used for file exchange. I've searched for a way to do the same thing with OpenSSH. So far haven't found it. If
