Installing Tectia Server on Linux

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 architecture.

The Tectia installation bundle contains the RPM files and the license file.

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

Make sure no other Secure Shell software is using port 22 (Tectia Server default listen port). Also make sure the firewall is open for port 22.
Download the installation bundle according to your platform and license type (commercial or evaluation):
- For 32-bit Linux platforms on x86 architecture:
```
tectia-server-<version>-linux-x86-comm.tar
tectia-server-<version>-linux-x86-upgrd-eval.tar
```
- For 64-bit Linux platforms on x86-64 architecture:
```
tectia-server-<version>-linux-x86_64-comm.tar
tectia-server-<version>-linux-x86_64-upgrd-eval.tar
```
In the package names, <version> is the current product release (for example, 6.4.14.123).
Unpack the downloaded tar package.
Select the installation packages (in this example, we install the x86-64 version). Two packages are always required: one for the common components of Tectia Client and Server, and one for the specific components of Tectia Server.
```
ssh-tectia-server-<version>-linux-x86_64.rpm
ssh-tectia-common-<version>-linux-x86_64.rpm
```
Install the packages with root privileges:
```
# rpm -Uvh ssh-tectia-server-<version>-linux-x86_64.rpm
# rpm -Uvh ssh-tectia-common-<version>-linux-x86_64.rpm
```
However, if you have already installed Tectia Client, there is no need to install the common file again.
The server host key is generated during the installation. The key generation may take several minutes on slow machines.
Copy the license file to the /etc/ssh2/licenses directory. (This is not necessary in "third-digit" maintenance updates.) See also License File.
If this is the initial installation of 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 Tectia Server manually after copying the license file.
The installation should (re)start Tectia Server automatically.
If Tectia 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
```
