How does IRC obtain the users in a channel?

I'm on an IRC server where the command /names is not a valid command. However, on programs like mIRC and Mibbit, the users in the channel still show up on the GUI where it displays the channel users. What command is being used to obtain the user list?

/who is not a valid command either. This network has over a few million registered/active users, so I don't think /who would work either.

Except /names and /who are both standard IRC commands listed in RFC specs. What network are you referring? Are you sure the client you're using simply does not support input of IRC commands in that manner?

irc.twitch.tv

I've tried mIRC, xChat, irssi, etc. and compared the same exact commands with other IRC networks which work fine with these commands.

Irssi: Unable to connect server irc.twitch.tv port 6667 [Connection timed out]
I couldn't connect using an IRC client.

The server is password-protected. You need to use your twitch OAuth token as the server password (found here: http://www.twitchapps.com/tmi), and your username as your twitch username.

In mIRC, connect to the server (but don't join any channels). Type /debug @d. Type /debug on. Type /join #channelname. Type /debug off. Switch to window @d and read through the output. That will tell you exactly what mIRC is sending and receiving.
(I did not test this today but I have done it on other servers in the past).

(I did not test this today but I have done it on other servers in the past).
Here is the debug output:

Code:
-> tmi.twitch.tv JOIN #linux
<- :sentralorigin!sentralorigin@sentralorigin.tmi.twitch.tv JOIN #linux
-> tmi.twitch.tv MODE #linux
<- :sentralorigin.tmi.twitch.tv 353 sentralorigin = #linux :sentralorigin
<- :sentralorigin.tmi.twitch.tv 366 sentralorigin #linux :End of /NAMES list
<- :jtv!jtv@jtv.tmi.twitch.tv PRIVMSG sentralorigin :USERCOLOR sentralorigin #FFFFFF
<- :jtv!jtv@jtv.tmi.twitch.tv PRIVMSG sentralorigin :HISTORYEND linux
<- :john!john@john.tmi.twitch.tv JOIN #linux
<- :sally!sally@sally.tmi.twitch.tv JOIN #linux
<- :jim!jim@jim.tmi.twitch.tv JOIN #linux
<- :james!james@james.tmi.twitch.tv JOIN #linux
<- :arty!arty@arty.tmi.twitch.tv JOIN #linux
<- :kev!kev@kev.tmi.twitch.tv JOIN #linux
<- :blue!blue@blue.tmi.twitch.tv JOIN #linux
<- :nate!nate@nate.tmi.twitch.tv JOIN #linux
<- :owner!owner@owner.tmi.twitch.tv JOIN #linux
<- :jtv MODE #linux +o owner
-> tmi.twitch.tv PRIVMSG #linux :test
<- :sentralorigin!sentralorigin@sentralorigin.tmi.twitch.tv PART #linux
-> tmi.twitch.tv PART #linux
<- :sentralorigin!sentralorigin@sentralorigin.tmi.twitch.tv PART #linux
All of those users that joined were already in the channel before me. So I guess it's some sort of weird thing.

It all most likely depends on the ircd being used on tmi.twitch.tv

/names in an unknown command, but names replies are still sent upon channel join (numeric 353 and 366).

Code:
-> tmi.twitch.tv JOIN #linux
<- :forbiddenlake!forbiddenlake@forbiddenlake.tmi.twitch.tv JOIN #linux
-> tmi.twitch.tv MODE #linux
-> tmi.twitch.tv WHO #linux
-> tmi.twitch.tv MODE #linux +b
<- :forbiddenlake.tmi.twitch.tv 353 forbiddenlake = #linux :forbiddenlake
<- :forbiddenlake.tmi.twitch.tv 366 forbiddenlake #linux :End of /NAMES list
<- :jtv!jtv@jtv.tmi.twitch.tv PRIVMSG forbiddenlake :HISTORYEND linux
<- :tmi.twitch.tv 421 forbiddenlake WHO :Unknown command
-> tmi.twitch.tv NAMES #linux
<- :tmi.twitch.tv 421 forbiddenlake NAMES :Unknown command
In short, this is a heavily modified IRCd that is not RFC compliant. "All commands described in this section [3] MUST be implemented by any server for this protocol. ... 3.2.5 Names message"

Excuse me for disturbing this topic!
I'm just wondering if irssi client has a /debug command by which I would be able to see all the twitch users of the channel.
