Как настроить irssi?

Вы задали много вопросов в одном, но я помогу вам как можно больше из них.

Во-первых, вам нужно добавить ваш IRC-сервер по своему выбору - запустите irssi и введите следующее:

/server add -auto -network Freenode irc.freenode.net 6667

Это добавит IRC-сеть Freenode в вашу конфигурацию IRSSI и будет автоматически подключаться при запуске irssi. [!d3 ]

/network add -nick <your-nick> Freenode

Это добавит ваш ник в новую сеть Freenode и будет автоматически использовать этот ник при подключении к сети.

/channel add -auto #ubuntu Freenode [ ! d6]

Это позволит вам присоединиться к #ubuntu в Freenode каждый раз, когда вы запускаете irssi.

Предполагая, что у вас зарегистрирован ник, вы можете сделать это, чтобы автоматически идентифицировать:

/network add -autosendcmd "/msg nickserv identify password ;wait 2000" Freenode

Вы можете переключаться между каналами с помощью Alt-2, Alt-3 и т. д., причем каждый канал является Alt-Number

Если вам интересно, вот мой [ f9] file:

servers = (
  { address = "irc.ubuntu.com"; chatnet = "Ubuntu"; port = "8001"; },
  #There is actually very little difference between irc.ubuntu.com
  # and irc.freenode.net - irc.u.c is just a redirect

    chatnet = "Freenode";
    port = "6667";
