This guide explains how to set up an SSH server on Debian Etch with public-key authorization (and optionally with disabled password logins). SSH is a great tool to control Linux-based computers remotely. It is safe and secure.

Are you using SSH in the best way possible? Have you configured it to be as limited and secure as possible? The goal of this document is to kick in the new year with some best practices for SSH: why you should use them, how to set them up, and how to verify that they are in place. All of the examples below assume that you are using EnGarde Secure Linux but any modern Linux distribution will do just fine since, as far as I know, everybody ships OpenSSH.

This document describes how to set up a chrooted SSH/SFTP environment on Fedora 7. The chrooted users will be jailed in a specific directory where they cannot break out. They will be able to access their jail via SSH and SFTP.

In this article I will show how to install and configure BlockHosts on a Debian Etch system. BlockHosts is a Python tool that observes login attempts to various services, e.g. SSH, FTP, etc., and if it finds failed login attempts again and again from the same IP address or host, it stops further login attempts from that IP address/host. By default, BlockHosts supports services that use TCP_WRAPPERS, such as SSH, i.e. services, that use /etc/hosts.allow or /etc/hosts.deny, but it can also block other services using iproute or iptables.

This tutorial describes two ways how to give users chrooted SSH access. With this setup, you can give your users shell access without having to fear that they can see your whole system. Your users will be jailed in a specific directory which they will not be able to break out of. The users will also be able to use SFTP in their chroot jails.

In this article I will show how to install and configure fail2ban on a Debian Etch system. Fail2ban is a tool that observes login attempts to various services, e.g. SSH, FTP, SMTP, Apache, etc., and if it finds failed login attempts again and again from the same IP address or host, fail2ban stops further login attempts from that IP address/host by blocking it with an iptables firewall rule.

This tutorial shows how you can set up a network-attached storage server with FreeNAS. FreeNAS is based on the FreeBSD operating system and supports CIFS (samba), FTP, NFS, RSYNC, SSH, local user authentication, and software RAID (0, 1, 5). It comes with a powerful web interface and uses very little space on the hard drive - about 32MB.

This is a description of how to set up a secure tunnel between your MySQL Server and a locally running MySQL Administrator using Putty. By creating a secure tunnel to your MySQL server using Putty, you can grant localhost access to powerful applications like MySQL Administrator while at the same time, make your server appear as if it isn't even there. In effect, make your MySQL server disappear from the outside world.

I guess you all know this: you are connected to your server with SSH and in the middle of compiling some software (e.g. a new kernel) or doing some other task which takes lots of time, and suddenly your connection drops for some reason, and you lose your labour. This can be very annoying, but fortunately there is a small utility called screen which lets you reattach to a previous session so that you can finish your task. This short tutorial shows how to use screen for just this purpose.

This guide describes how to generate and use a private/public key pair to log in to a remote system with SSH using PuTTY. PuTTY is an SSH client that is available for Windows and Linux (although it is more common on Windows systems). Using key-based SSH logins, you can disable the normal username/password login procedure which means that only people with a valid private/public key pair can log in. That way, there is no way for brute-force attacks to be successful, so your system is more secure.
