Linux FAQs with Answers--How to install autossh on Linux
|
|
================================================================================
|
|
> **Question**: I would like to install autossh on [insert your Linux distro]. How can I do that?
|
|
|
|
[autossh][1] is an open-source tool that allows you to monitor an SSH session and restart it automatically should it gets disconnected or stops forwarding traffic. autossh assumes that [passwordless SSH login][2] for a destination host is already setup, so that it can restart a broken SSH session without user's involvement.
|
|
|
|
autossh comes in handy when you want to set up [reverse SSH tunnels][3] or [mount remote folders over SSH][4]. Essentially in any situation where persistent SSH sessions are required, autossh can be useful.
|
|
|
|
|
|
|
|
Here is how to install autossh on various Linux distributions.
|
|
|
|
### Install Autossh on Debian or Ubuntu ###
|
|
|
|
autossh is available in base repositories of Debian based systems, so installation is easy.
|
|
|
|
$ sudo apt-get install autossh
|
|
|
|
### Install Autossh on Fedora ###
|
|
|
|
Fedora repositories also carry autossh package. So simply use yum command.
|
|
|
|
$ sudo yum install autossh
|
|
|
|
### Install Autossh on CentOS or RHEL ###
|
|
|
|
For CentOS/RHEL 6 or earlier, enable [Repoforge repository][5] first, and then use yum command.
|
|
|
|
$ sudo yum install autossh
|
|
|
|
For CentOS/RHEL 7, autossh is no longer available in Repoforge repository. You will need to build it from the source (explained below).
|
|
|
|
### Install Autossh on Arch Linux ###
|
|
|
|
$ sudo pacman -S autossh
|
|
|
|
### Compile Autossh from the Source on Debian or Ubuntu ###
|
|
|
|
If you would like to try the latest version of autossh, you can build it from the source as follows.
|
|
|
|
$ sudo apt-get install gcc make
|
|
$ wget http://www.harding.motd.ca/autossh/autossh-1.4e.tgz
|
|
$ tar -xf autossh-1.4e.tgz
|
|
$ cd autossh-1.4e
|
|
$ ./configure
|
|
$ make
|
|
$ sudo make install
|
|
|
|
### Compile Autossh from the Source on CentOS, Fedora or RHEL ###
|
|
|
|
On CentOS/RHEL 7, autossh is not available as a pre-built package. So you'll need to compile it from the source as follows.
|
|
|
|
$ sudo yum install wget gcc make
|
|
$ wget http://www.harding.motd.ca/autossh/autossh-1.4e.tgz
|
|
$ tar -xf autossh-1.4e.tgz
|
|
$ cd autossh-1.4e
|
|
$ ./configure
|
|
$ make
|
|
$ sudo make install
|
|
|
