The host public-key pair (1536-bit RSA) is generated during the installation of SSH Tectia Server. You only need to regenerate it if you want to change your host key pair.
The command-line tool ssh-keygen-g3
can be
used to generate the host key pair. It can be used for creating
the user key pairs as well.
On Unix, to (re)generate the host key, give the following command with root privileges:
# ssh-keygen-g3 -P -H hostkey
On Windows, to (re)generate the host key, give the following command:
ssh-keygen-g3.exe -P -H hostkey
This will generate a 2048-bit DSA key pair (without a passphrase)
and save it in the default host key directory (/etc/ssh2
on
Unix, "C:\Program Files\SSH Communications Security\SSH Tectia\SSH Tectia Server
" on Windows) with the names
hostkey
and hostkey.pub
. For more information
on the key generation options, see ssh-keygen-g3(1).
After the new key pair has been created, run
ssh-server-config-tool
to reconfigure the server.
See ssh-server-config-tool(8).
