As I have written more about umodes than I thought, I am breaking the posts setting/unsetting is documented here and I will link here from other posts.

Simply use /umode +mo-des or if that is unknown command (as it’s alias in most of clients), use /mode YOURNICK +mo-des and you set umodes “mo” and unset “des”. These might not be real umodes and they are here just as an example.

Automatic umodes

Umodes aren’t remembered across connections so you must configure your client to (un)set them automatically. Your umodes won’t be change this way until you reconnect!

These examples use the umodes that I am using at the time of writing.

  • HexChat: Open network list, select network and click edit, open tab Connect commands, click add and type umode -iI+wRQxg.
  • WeeChat
    • Old way: /set irc.server_default.command /mode $nick -iI+wRQxg
    • Modern way (1.7+): /set irc.server_default.usermode -iI+wRQxg
    • For setting umodes only for one network instead of them all replace server_default with, e.g.
      • /set irc.server.liberachat.usermode -iI+wRQxg
  • ZNC:
    • Traditional way: /msg *status loadmod perform and /msg *perform add mode %nick% -iI+wRQxg
      • The same can also be done in webadmin and if you load perform for user level, adding the command mode %nick% -iI+wRQxg will set umode -iI+wrqXG on all networks.
      • The modes will apply to all networks if you load it on user level or only the invidual network on network level.
    • Modern way: ZNC issue #1221

And what these umodes mean

This list is what I want the umodes to mean when I set them automatically. For what the actual umodes are on your network, try /quote help umode or /quote help umodes.

  • i — invisible, hides your channel list from whois with ircd-seven and possibly some other ircds. Also hides you from /who of people who don’t share channels with you. See also why I unset it here.
  • I — On InspIRCd with [hidechans] module hides your channel list from whois.
  • w — receive wallops, less-important announcements from network operators that are only received by those who are curious and have umode +w. More important announcements are usually global notices.
  • R — block PMs from unidentified users (who tend to be spambots and if they aren’t, they can identify to services).
  • Q — block channel redirects on Charybdis (mode +f or banforward).
  • x — activates IRCd based uncloaking even if it’s not that reliable.
  • g — caller-id, people must be /accepted or PMed before they can PM you.
  • t — only users using SSL can PM.
