This is a review of most frequently asked questions, so please have a look here first and see if there is an answer to your question before going in the help channels and asking.
Undernet provides a chat environment for many people. Around a million users connect to the Undernet in a week's time, so you will probably have your share of lamers. Here are some few tips on protecting your channel, and yourself, from their attacks. As a general rule, be polite to your fellow chatters while on IRC. Show decency and respect, and you will get the same in return.
You may want to take a look at the "User and Channel modes" section of the FAQ, for reference on the modes being mentioned in what follows.
A drone is a trojan which makes a computer connect to IRC without the knowledge and approval of the owner of that computer. They can usually be identified from using the same nick/ident/real name.
A bot is defined as any type of autonomous software that operates as an agent for a user or a program or simulates a human activity. In short, it is an automated computer program.
If your channel is being flooded by a large number of bots or drones, they will usually join, message the channel, part, change nicks etc, and you will have little chance of keeping them out by simple bans.
To prevent people from joining the channel unless an OP invites them in, you can use:
/mode #channel +iThis way, the drones won't be able to join, but the bad part is that no one else will be able to join either, if you do not invite them one by one.
Another option is to set the channel so only users that are registered to X and logged in can join it:
/mode #channel +rFlood bots don't log in to X, so this keeps them out, but it will also keep out people that are not registeredto X or who haven't registered usernames. But this channel mode is effective against flood bots, and it should be regarded as a long-term decision, longer than the +i anyway.
The best way to keep drones off your channel though, is to set wide bans. For example, if you notice that you've been flooded by drones that have "domain.net" in their host, you can always set a ban like:
/mode #channel +b *!*@*.domain.orgThe non-ident ban is widely used, because most drones do not respond to the server's ident request, and thus they receive a ~ in front of their ident. They look like email@example.com . So if you notice that this kind of drone is flooding you, you could set:
/mode #channel +b *!~*@*
It is possible that someone uses the bots or drones that they command to attack you directly, and not the channels that you are in. In this case, they command their bots/drones to send you private messages, notices, CTCP requests etc, causing you to connect from so much traffic.
- The Ignore Function.
This is where we introduce the Ignore function. The command is /ignore nick!ident@host, and it works exactly like the ban command, only that you are banning the users you specify from sending you private messages. The ignore command works with some switches, so you can specify what exactly to ignore. For example:
/ignore -n *!*@*would ignore all private notices being sent to you. The switches for the ignore command are -p for private, -c for channel, -n for notice, -t for ctcp, -i for invite, -k for control codes, and -d for dccs. You can get the syntax and the switches by typing:
- The Silence Feature.
Undernet offers a special type of ignore command that is called Silence. This command tells the server to not send any information from the nick being silenced. In short, it is an ignore command that blocks the data being sent from the server to you. The silence settings are cleared when you disconnect from the server, but the ignore list is memorized in the IRC client. The command is:
/silence +nickTo remove it, type:
/silence -nickIt is good to keep an alias for activating flood protection, because floods take you by surprise, and it is nice to protect yourself only by hitting a few keys. If you do not know what aliases are, or how to use them, I suggest you type /help aliases
Here are some aliases that are good to have:
/f //silence +* | //ignore *!*@* | //mode $me +dThis one makes you fail-proof against lamers trying to disconnect you by flooding you off the server. It silences all nicknames, ignores all nicknames, and sets you deaf so you cannot see channel text. Keep in mind that you won't be able to see ANY text from anyone until you disable the protection. For that, build another alias that should look like:
/-f //silence -* | //ignore -r *!*@* | //mode $me -dFinally, do not hesitate to report ALL abuses directed at you to IRC Operators or to help channels. In case the abuser is doing Denial of Service (DoS) attacks on you, you should write an email to the abuse department of their ISP (Internet Services Provider). You can get the email addresses of their ISP by following two simple steps:
- Get their IP by doing a /whois nickname
- Visit http://www.ripe.net/db/whois/whois.html and type the IP there.
- The Ignore Function.
Hope you have a safe ride on the Undernet :)
