Seeking Network geeks please...

My better half is supposed to download her work from a mail server on port 22.
We have turned off all firewalls, but can't 'telnet' it.
We have asked our ISP, PlusNet, to try it, they can't do it, not even on their own and/or Telewest cable connection, however they reported tat they can telnet on port 25.
Turns out we can also telnet on port 25, but not 22 !

The Swiss company swears the server is working and accesible on port 22.
This has been going on for weeks, my family will be starving very soon...

Can anyone here "telnet 212.243.7.194 22" ?
Better still, why is it not working for us ?
Thanks,
regards,
Martin

Are you 100% sure the port is 22?

22 is normally SSH, 25 is one of a possible few for SMTP.

I've never heard of any one running a SMTP server on port 22.

Edit:... that said, port 22 on that IP is open but appears to do nothing.

:~ mattm$ telnet 212.243.7.194 22
Trying 212.243.7.194...
Connected to mail.cls-communication.com.
Escape character is '^]'.

whereas port 25 is running the mail server..

:~ mattm$ telnet 212.243.7.194 25
Trying 212.243.7.194...
Connected to mail.cls-communication.com.
Escape character is '^]'.

Have you tried to use port 25 instead in your client?

Double Edit: You say download mail from the server? SMTP is normally used to send mail to a server (i.e outbound messages). If you want to download from the server, you'd normally use POP3 (110) or IMAP (143) (or SSL variants of the two 993/995).

And ports 23 (TELNET). 110 (POP3), 143 (IMAP) are all closed. Port 22 must be awaiting her login.

But it isn't requesting anything...

Just sitting there, so could be SSH that only actively responds to known (trusted) IP addresses.

Mail clients (in and out) work on a challenge/response type transaction. Port 22 isn't presenting a challenge, so nothing can be given as a response.

It's not port 22 hex (34 decimal) is it?

According to Wiki, that's the port for "Remote File (RF)�used to transfer files between machines".

There's no significant challenge between typing "login:" and typing nothing

Can they not just email it to her in the normal way?

I don't follow.

POP/IMAP/SMTP servers will generally welcome you before you even send anything, to which the transaction would start.

That server isn't welcoming as you would expect for SMTP/POP/IMAP connections which makes me think the port isn't right.

Sorry, I just meant it could start by just typing a empty string. Once you've logged in once you will always know what to expect subsequently.

Generally!

You're probably right, but it ain't necessarily so!

He probably didn't mean a "mail server" but just downloading work = files.
