In a text editor (you will probably have to use “sudo”), and find the line that starts with “Subsystem sftp”. We need to configure the sftp subsystem to use the internal sftp module.

It is possible that ssh is not installed, so: $ sudo apt-get install ssh (1) Installation and initial configuration

The purpose of this guide is to demonstrate how to set up a simple chrooted sftp system from square one implementing this self-contained chroot mechanism (using only openssh without the need for rssh), and how to add users under this paradigm. Since version 4.8, openssh has had the ability to (fairly) easily chroot sftp users into a specified directory using a new sshd_config directive, ChrootDirectory. Your noob-radar should be flashing right about now ). I had been wanting to set up an encrypted-transaction FTP server for a while (SFTP) in a chrooted environment, so I did a few hours of half-baked-blog parsing and keyboard-pounding in order to figure this out in a way that would work consistently, even if it isn’t 100% efficient. Posted in Linux Tips - How to How to set up and chroot SFTP users with OpenSSH in Ubuntu PS: we can install fail2ban to protect our ssh service use ssh key for scp or rsync without enter user/password. We add a limit user with rssh shell and chroot to their own /home/rsshuser this user can use sftp, scp, rsync to their chroot home folder only.

Default port none – ( openssh 22 port used – rssh is shell with security features).

Default rssh binary location /usr/bin/rssh (FreeBSD – /usr/local/bin/rssh).

Default configuration file is located at /etc/nf (FreeBSD – /usr/local/etc/nf).

Make sure you build binary with rsync support. $ sudo apt-get install rssh FreeBSD installation # rpm -ivh rssh-2.3.2-1.2.el5.rf.i386.rpm Debian / Ubuntu Linux rssh installation Install rssh CentOS / Fedora / RHEL Linux rssh installation

rdist – Backup / RDist program maintains identical copies of files on multiple hosts.

cvs – Concurrent Versions System ~ you can easily retrieve old versions to see exactly which change caused the bug.

Restricted shell only allows following operations only: For example, if you have a server which you only want to allow users to copy files off of via scp, without providing shell access, you can use rssh to do that. It now also includes support for rdist, rsync, and cvs. Rssh is a restricted shell for use with OpenSSH, allowing only scp and/or sftp. It also covers chroot jail setup instructions to lock down users to their own home directories (allow users to transfer files but not browse the entire Linux / UNIX file system of the server) as well as per user configurations. In this article series we will help you provide secure restricted file-transfer services to your users without resorting to FTP. SCP/SFTP -> SSHD -> Call sftpd subsystem -> Requires a shell -> User can login to server and run other commands. Basically OpenSSH requires a valid shell. However, this feature also grants ssh shell access to a user.

You can use OpenSSH Server to transfer file using SCP and SFTP (secure ftp) without setting up an FTP server. FTP is insecure protocol, but file-transfer is required all time.
