Installing SSH Tectia Server on Linux

SSH Tectia Server for Linux platforms is supplied in RPM (Red Hat Package Manager) binary packages for Red Hat Enterprise Linux and SUSE Linux. There are separate packages for Linux versions running on the 32-bit x86 and the 64-bit x86-64 platform architecture.

The online installation package contains the RPM files.

On the installation CD-ROM, the installation packages for Linux are located in the /install/linux/ directory.

Two packages are required: one for the common components of SSH Tectia Client and Server, and another for the specific components of SSH Tectia Server.

To install SSH Tectia Server on Linux, follow the instructions below:

Make sure no other Secure Shell software is using port 22 (SSH Tectia Server default listen port).
Select the installation package according to your Linux version.
When installing on Linux running on the 32-bit x86 architecture, select the following packages:
```
ssh-tectia-common-<ver>.i386.rpm
ssh-tectia-server-<ver>.i386.rpm 
```
When installing on Linux running on the 64-bit x86-64 architecture, select the following packages:
```
ssh-tectia-common-<ver>.x86_64.rpm
ssh-tectia-server-<ver>.x86_64.rpm
```
In the commands, <ver> is the current package version of SSH Tectia Server (for example, 5.3.0.123).
Install the packages with root privileges:
```
# rpm -Uvh ssh-tectia-common-<ver>.<arch>.rpm
# rpm -Uvh ssh-tectia-server-<ver>.<arch>.rpm
```
In the commands, <arch> is the platform architecture i386 or x86_64.
The server host key is generated during the installation. The key generation may take several minutes on slow machines.
(Not necessary in "third-digit" maintenance updates.) Copy the license file to the /etc/ssh2/licenses directory.
If this is the initial installation of SSH Tectia Server, the directory does not yet exist. You can either create it manually or copy the license after the installation. In the latter case, you have to start the server manually after copying the license file.

The installation should (re)start the server automatically.

	Note
	If the server does not start (for example because of a missing license or because some other secure shell software is running on port 22), you can start it after correcting the problem by issuing the command:

# /etc/init.d/ssh-server-g3 start
