Hi Ludolf,

It's again : 

3 hosts : 
[host1]----[host2]---[host3]

1) stunnel : host1 -> host2
2) stunnel : host3 -> host2
3) telnet : host1 -> host3 via stunnel and via host2

Kind regards,
Gabor

Gabor,

I still don't understand which unit you want to act as a server and
which as a client for each connection.

The telnet client is a client at any case.  On request of a user, the
telnet client establishes a connection to e.g. the stunnel instance on
host1.

The telnet server is a server at any case.  A server doesn't establish
connections, but waits for incoming connections.  So who is supposed
to establish the connection between the stunnel instance on host3 and
the telnet server, and on whose request?

What does the term 'server' refer to in this sentence?


Maybe it helps if you explain the application you are trying to set
up.  In a previous mail, you mentioned HTTP, so I think there is a web
browser (e.g. Firefox) and a www server (e.g. Apache) you want to
connect.  Is that correct?

Ludolf
