Make sure no other Secure Shell software is using port 22 (Tectia Server default listen port). Stop any competing server software or change their listen port.

Download the commercial or the evaluation version of the installation bundle according to your license type:

tectia-server-ibm-z-<version>-linux-s390-comm.tar
tectia-server-ibm-z-<version>-linux-s390-upgrd-eval.tar

In the package names, <version> indicates the product release (for example, 6.3.14.123).

Select the installation packages. Two packages are required: one for the specific components of Tectia Server for Linux on IBM System z, and another for the common components of Tectia Client and Server:

ssh-tectia-server-<version>-linux-s390.rpm
ssh-tectia-common-<version>-linux-s390.rpm

Unpack the downloaded tar package.

Install the packages with root privileges:

# rpm -Uvh ssh-tectia-server-<version>-linux-s390.rpm
# rpm -Uvh ssh-tectia-common-<version>-linux-s390.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. See License File.

If this is the initial installation of Tectia Server for Linux on IBM System z, 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.

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
