Virtual Telnet and Virtual POP

How to setup a Virtual telnet for virtual domains on my server? (i.e. telnet virtual-domain.com)

Also, how to config the POP so that each virtual domain is like to have each unique POP server? (They could setup any pop mailboxes wihtout limitation on username overlapping with other virtual domains on the same machine)

I found certain virtual servers providers are doing this.

There is no logic in virtual telnet daemons, because, afterall, all the connections end up on the same machine, doing the same shell. You can have two domains on the same machine, that's not a problem. But you will need two IPs (at least). The POP server cannot distinguish between domains, I.E. you cannot have Dave@virtual1.com being able to read his mail on Dave@virtual1.com and not being able to read that very same mailbox on Dave@virtual2.com (if both of those mailboxes are actually same mailbox on one single machine). The only thing two domains on the same machine can do separately are webservers, news, gopher, ftp, irc...and smtp to the extent that it would handle both virtual domains, and that (if mailers configured properly) the From: field would be different in both cases.

That can't be right, my providor does it too.  They setup virtual pop servers for each virtual account.  You can setup any usernames you want for the pop server.
Maybe they have some custom software.

The POP3 thing:

To do this you would need to do the following:

Set up sendmail to place different domain mail into a different directory area. (Sould be a piece of cake)

Create a new version of POP that was virtual domain educated. To do this you would need a POP that could recognise what IP address the POP client is connecting to, and use the domain directory based on that connection address.
(There's possibly a POP out there that'll do this, but I havn't seen it yet.)

You would need to maintain a seperate user database for each virtual domain that you wish to host.

The telnet thing:

Same as the POP server.  You need to get a telnetd that recognises what IP address the client is connecting to, and uses the appropriate user database to log the user in, and give the user the correct directory.

(Probably want to do the same for FTPD as well I suppose)

I can do this work for you if you mail me

Virtual telnet? You people amaze me...
What is the difference if I log in on virtual1.com as user 'pee'
and home of /home/pee and if I log in on virtual2.com as user 'wee' and home of /home/wee if I have a shell below me?
Think about it kids...harder this time...

PELE is right about the "virtual telnet". However you can do it by setting up your machine with mulitpleip addresses. You can dot his by typing ifconfig eth0. Say it has an address of .1.

You can add an ip address of .2 to it by typing ifconfig eth0:1 "new ip address" .
Type ifconfig after this and it will show you that your eth) interface will have two ip addresses assigned to it.

Then you can set up any "virtual" services you like.

Sendmail is a bit of a bitch to configure but get the latest version of it and this should give you enough info to set it up.

Thus you could have aaa@aaa.com and aaa@bbb.com, aaa.com and bbb.com being on the same server and being virtual servers,

If you need more help mail me at jasons@aone.com.au
