![]() Warning: The scp protocol is outdated, inflexible and not readily fixed. More features are available by installing additional packages, for example rssh AUR or scponly described below. It contains the scp utility to transfer files. ![]() This service allows sftp connections only. The ssh server should return a polite notice of the setup: Test that in fact, the restrictions are enforced by attempting an ssh connection via the shell. See SFTP chroot to configure the keys correctly when using chroot or it will get permission denied. Restart rvice to re-read the configuration file. # useradd -g sshusers -d /var/lib/jail fooĪdd the following to the end of /etc/ssh/sshd_config to enable the share and to enforce the restrictions: Create an unprivileged userĬreate the share user and setup a good password: Tip: Consider adding an entry to /etc/fstab to make the bind mount survive a reboot. # mount -o bind /mnt/data/share /var/lib/jail It is owned by root and has octal permissions of 755. In this example, /mnt/data/share is to be used. Optionally, bind mount the filesystem to be shared to this directory. Users with this type of setup may use SFTP clients such as filezilla to put/get files in the chroot jail. This can be useful to simply share some files without granting full system access or shell access. Sysadmins can jail a subset of users to a chroot jail using openssh thus restricting their access to a particular directory tree. Secure file transfer protocol (SFTP) with a chroot jail ![]() Many standard FTP programs should work as well. Once running, SFTP is available by default.Īccess files with the sftp program or SSHFS. The SFTP protocol, however, features additional capabilities like, for example, resuming broken transfers or remote file manipulation like deletion. Both protocols allow secure file transfers, encrypting passwords and transferred data. The SSH file transfer protocol (SFTP) is a related protocol, also relying on a secure shell back-end. The Secure copy (SCP) is a protocol to transfer files via a Secure Shell connection. (Discuss in Talk:SCP and SFTP#Incorrect 'Considered for redirection' banner?)
