http ports question

[joinT]

Hey guys - basically here's the deal.
I have my little dev server, that's running a web server (port 80)

i also run (every once in a while) a UT or Tactical Ops server.
the web administration for Tactical Ops I set to 8080.
i set the UT remote admin port to 80, but now I can't access the UT remote admin - i think because of the web server.

i know i could pretty much use any port - but I'm just wondering if there are any other precedents like 8080 & if there are benefits to using them.

TIA

Pick a port, any port!

8080 was used because it's easy to remember, two 80's. Just don't use a common port like 21 (ftp) etc....

Here's a quick list of common ports for ya:

7 - Echo
21 - FTP
23 - Telnet
25 - SMTP
53 - DNS
79 - finger
80 - HTTP
110 - POP3
119 - NNTP
161 - SNMP
162 - SNMP Trap

Don't ask me what some of those are cuz I have no idea!

2 server's can't use the same port at the same time, if you stop the web server the UT admin server will work fine.

7 - Echo - TCP ping
21 - FTP - File Transfer Protocol
23 - Telnet - insecure remote shell access
25 - SMTP - Simple Mail Transport Protocol, server's moving email around
53 - DNS - Domain Name resolution
79 - finger - see who's login to remote server and other things.
80 - HTTP - HypterText Transport Protocol
110 - POP3 - PostOffice Protocol v3, email client access
119 - NNTP - news, don't remember the acronym off hand
161 - SNMP - Simple Network Management Protocol, lots of statistics about the PC running it.
162 - SNMP Trap - SNMP can send a 'trap' when a certain stat hits a certain value, alerting you to possible bad or good circumstances.

1024> are reserved ports, dont use those.

Anything above 1024 is pretty much up for grabs.

Oh and if two apps want to listen on the same port, one wont work.

yea, I realize the web server & UT's built in web server are clashing.
On my router - I can choose the ports to open by application. There's HTTP, HTTPS, & even HTTP8080 which is cool.

thanks for the tips - I'd forgotten I should stay above 1024 & that list is useful.
thanks again
