Hello,

Well you could try a command like:
to check if another package provides telnet binary.
Also be aware that some tools like netcat easily allows you to connect to a telnet server.

Kind regards,

Oliv'

Why do you want to do that

Wouldn't it be the better approach to remove telnet from the server, since it is deprecated and insecure?

That would be my preference; I was giving the OP the benefit of the doubt there... should have asked anyway .

It's why I asked. Still waiting for the reply
