That's correct, forgot to mention it. We ended up using SFTP (or at least offering it to external). -----Original Message----- From: CentOS [mailto:centos-bounces at centos.org] On Behalf Of rainer at ultra-secure.de Sent: Dienstag, 24.

I've done that exactly once (chrooted ssh) and it was such a pain that I vowed to never do it again. The problem is that inside the chroot, you need: - nameresolution - a minimal passwd/shadow/group file (or ldap) - maybe for scp, you can get away with a rather minimal device-tree - but for actual SSH access, I needed a fairly complete device tree inside the chroot (ttys ...). - that was with FreeBSD 10, I never tried it with anything else (due to its history with jails, creating functional, limited chroot-environments is somewhat in its genes, so to speak) Somebody sent me the link to these scripts: https://github.com/codelibre-net/schroot Maybe you can use those scripts - I've never tried them. Also, there's scp-only: https://github.com/scponly/scponly/wiki Haven't used that in years, either. Concern over that one seemed to be that it's "another" shell and nobody had apparently done a thorough audit of it. _______________________________________________ CentOS mailing list CentOS at centos.org https://lists.centos.org/mailman/listinfo/centos
