RE: [cobalt-users] Cube3 DNS problem

["Steve Groom" <steve.groom@xxxxxxxxxx>]

Hi Gerald et al,
the DNS problem is mostly solved.

Externally no errors. Internally ( from Telnet) on DNS1 I can mail to
cobalt@xxxxxx (mail is running on an Apple server).

However from the other two servers mail cobalt@xxxxxx results in:

[admin admin]$ mail cobalt@xxxxxx
Subject: Test
test
Cc:
[admin admin]$ cobalt@xxxxxxxxx User unknown
/home/sites/home/users/admin/dead.letter... Saved message in
/home/sites/home/users/admin/dead.letter

This is really weird.

AND NOW A DUMB QUESTION
I know I have to switch off TELNET and install SSH, but I have not any clues
about the whole picture - what exactly do I need to do - I'm fairly sure
that I can D/L and install the SSH package from the cobalt site, but what
else do I need to do to complete securing my servers?

Can anyone point me in the right direction.

best regards
Steve

I assume you have your DNS fixed!
I did 'dig' on www.mep.ch, mep.ch, and mail.mep.ch and they show NOERROR
I did http on mep.ch and www.mep.ch and they work.
THEN!
I did telnet mep.ch and it worked.
I did telenet mep.ch 25 and it worked.
So, it's obvious that by now your Qube3 is HACKED!
For crying-out-loud PLEASE install SSH and turn telnet OFF!

Gerald
