Virtual domains for all daemons

Question

linux

There is a VPS server under Debian with 1 ip-address.
Several domains are attached to it. Is it realistic for them to leave only port 80 open (lighttpd).
And on some private.site.com already hang sshd, proftpd, a couple of control panels with a web interface, deluge. And on share.site.com there is already ftpd with anonymous access.

Most of this software does not know how to work with virtual domains, is it possible to teach them how to do this with some third-party software? Thank you.

Answer 1

And what, exactly, is the problem? We assign the same ip to all domains, different services work on different ports (web - 80 (443), ssh - 22, ftp - 21, etc.). Control panels with a web interface can hang on one port, we scatter them using light tools across different "virtual hosts" (or by uri, i.e. site.com/webmin).

Answer 2

demons "hang" on interfaces (or on ip-addresses), not on "domains". the fact that you see different content on different “domains” with the same address is exclusively a feature of the http protocol.
