Enroll a certificate for the server.

This can be done with the ssh-cmpclient-g3 command-line tool, for example:

$ ssh-cmpclient-g3 INITIALIZE \ 
  -P generate://ssh2@rsa:2048/hostcert_rsa \
  -o /etc/ssh2/hostcert_rsa \
  -p 62154:ssh \
  -s "C=FI,O=SSH,CN=testserv;dns=testserv.ssh.com" \
  http://pki.ssh.com:8080/pkix/ \
  'C=FI, O=SSH Communications Security, CN=Secure Shell Test CA'

Note that the DNS address parameter (dns) needs to correspond to the fully qualified domain name of the server.

Remember to define also the SOCKS server (-S) before the CA URL, if required.

For more information on the ssh-cmpclient-g3 syntax, see ssh-cmpclient-g3(1).

Define the private key and the server certificate in the ssh-server-config.xml file:

<params>
  <hostkey>      
    <private file="/etc/ssh2/hostcert_rsa" />
    <x509-certificate file="/etc/ssh2/hostcert_rsa.crt" />
  </hostkey>
...
</params>

Alternatively, when using the Tectia Server Configuration tool, enter the private key and certificate filenames on the Identity page. See Identity.

Run ssh-server-ctl to take the new configuration in use. See ssh-server-ctl(8).

On Windows, just click Apply to take the new settings in use.
