Installing Tectia Client on Linux (RPM)

Tectia Client for Linux is supplied in RPM (Red Hat Package Manager) binary packages for Red Hat Enterprise Linux, Rocky Linux and SUSE Linux running on the 64-bit x86-64 architecture.

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

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

Download the relevant installation bundle according to your license type:
- Commercial Tectia Quantum Safe Edition License:
```
tectia-client-<version>-linux-x86_64-comm-pqc.tar
                    
```
- Commercial License:
```
tectia-client-<version>-linux-x86_64-comm.tar
                    
```
- Evaluation:
```
tectia-client-<version>-linux-x86_64-upgrd-eval.tar
```
In the package names, <version> corresponds to the release version and build number, for example 6.6.3.123.
Unpack the downloaded tar package.
Select the installation packages. Two packages are always required: one for the common components of Tectia Client and Server, and one for the specific components of Tectia Client. If you want to use the product with a graphical user interface (GUI), install also the optional GUI support package.
```
ssh-tectia-common-<version>-linux-x86_64.rpm
ssh-tectia-client-<version>-linux-x86_64.rpm
ssh-tectia-guisupport-<version>-linux-x86_64.rpm
```

Install the packages with root privileges:

# rpm -ivh ssh-tectia-common-<version>-linux-x86_64.rpm
# rpm -ivh ssh-tectia-client-<version>-linux-x86_64.rpm
# rpm -ivh ssh-tectia-guisupport-<version>-linux-x86_64.rpm

Or upgrade the packages if you already have an older Tectia Client version installed:

# rpm -Uvh ssh-tectia-common-<version>-linux-x86_64.rpm
# rpm -Uvh ssh-tectia-client-<version>-linux-x86_64.rpm
# rpm -Uvh ssh-tectia-guisupport-<version>-linux-x86_64.rpm

Copy the license file to the /etc/ssh2/licenses directory. (This is not necessary in "third-digit" maintenance updates.) See also License File.
