why port 6667?

sickmusic · Guest

why do most servers use port 6667?

im at work and cant connect to any channels. i think its because the firewall blocks traffic from port 6667..

or am i wrong?

also..
does anybody have any resources that shows me how to set up my own mirc server?

port 6667 is just a default port, which is why that port is blocked at work. i dont know how they originally decided on it. if you want to set up your own server, i'd recommend googling "unrealircd" or "wircd" (if you want to go the windows route) and doing a little homework from there.

Another option is to use port forwarding, and bounce off of an unblocked port to an external port 6667.

Port numbers are used for different protocols, such as telnet, HTTP, email, ftp, and IRC servers. To make things consistant, there are default ports for each protocol. The administrator doesn't have to use that port, and they can add more, but as a general rule you should get through to the IRC server if you connect to its default port of 6667. Servers on large networks often add many more ports, allowing user connections on 6660, 6661, 6662, 6663, 6664, 6665, 6666, 6667, 6668, 6669, and 7000, and I have seen servers use 7700, 7777, 8080, and 8888. If the IRC server is on a dedicated machine, or one owned by the IRC admin, he/she may have a port that connects to IRC that is outside of the range detected by your firewall. You can also connect to IRC through some ssh systems. The best way to find out is to ask the admin of your favorite IRC server. This is not an unusual problem so some admins have set up non-public ports they may be willing to share with you.

However, a word of advice - if you value your job I wouldn't suggest doing anything that overtly circumvents the limits your employer has placed on your internet activities. It might be better to IRC from home or a portable device such as a laptop, palm pilot, or even a cell phone that has access.

There is no such thing as a mirc server. mIRC is an IRC client - it is a program on your computer that connects to an IRC server. Starting your own IRC server is not very difficult these days. You can set up an irc server on your home computer if it has a very good connection, but if you want something dependable that other people can use, then you'll need a shell, and basic knowledge of unix. By basic I mean, if you have enough skill to set up a bot on a shell on your own, you'll have no problem setting up an IRC server.

as far as good hosts that support php and all that good stuff... try http://www.darktides.net. i've known the founder of that hosting company forever, and he has some great prices. i've hosted my site there for a long time with no problems and the support is excellent. and the suggestion to use an existing server to host your chatroom is probably a pretty good idea. a lot of us (the folks who post regularly) have our own networks so whichever avenue you decide to pursue, someone will be more than eager to help. shop around for a good network that will fit your community. or if you decide to go the ircd route, let one of know and we can point you in the direction of a good shell provider.

mregit.. ur a star.

thanks very much for that info.

okay another few questions..

back to the original topic of port 6667..

how can i change the port number? or does the server admin have to change it?

will it be controlled on the server/client side?

Jason, mentioned bouncing off unblocked ports? any more info?

the reason i ask this is because i intend to develop my site from work, as i have a bit of time to spare in between jobs. we currently access the internet through a firwall hence have a http proxy "proxy.adomainname.com" on port 80.

i understand port 80 is used for html?? can this also be used for IRC?

sickmusic, I'm a bit confused what you mean when you say you are trying to develop a site. Do you want to set up a website with an IRC client built into it, that multiple people will use to connect to one channel? Or do you want to build up a channel that you will need to access via a port redirect?

Yes.... but

You can set up a java client to use a port the IRC admin has opened - say, port 5050. The java client will let everyone connect from their own computer, to the IRC network, and they will appear with their own IP.

If you set up a port redirect for the java client, then people will be connecting to a remote server that then directs everyone to the IRC server, and everyone will have the IP of the redirect server. This usually isn't done because most networks limit the number of connections from a given host, and if one user gets K lined you will ALL get K lined.

Unless the majority of your users have the same firewall problem you do, there really is no need for the IRC client to connect to an unusual port.

As for your own connection, there are all sorts of options available - the simplest, and most secure, is to IRC from a shell using a unix client, such as bitchx (www.bitchx.org). Bouncers are also popular (google irc bouncer, there are many available) that will let you connect mIRC to a telnet session and appear on IRC with the IP of the shell. Because both of them use telnet ports, they should be able to get through your firewall without a problem. If neither of those two options works for you, then you may want to investigate ssh port forwarding: http://skylab.org/~plumpy/ssh.html

hi people.. its me again.. Smile

okay,

ive been digging around and it looks like im gonna go for the PJIRC firsty because its free Surprised

secondly its opensource and has tonnes of mods. One o the mods i thought that wud be useful is its integration with phpbb usernames..

okay heres another query, ive looked at freeserve chat, and it appears that the applet uses port 7000. Another observation was that it uses port 7000 and listens for http tunnel data.

is this a standard feature of IRC?
to elaborate further, if i was to ask an IRC server admin to enale port 7000 and set up PJIRC to listen on that port, will it work in the same way as freeserve?

the reason i ask is because i can use freeserve chat at work with no problems, and most of my other members can also use it..

Thanks so much.. i know i am being a bit of a pain now :oops:
