EFnet
Encyclopedia
EFnet or Eris Free network is a major IRC network, with more than 35,000 users. It is the modern-day descendant of the original IRC network.

History

Initially, most IRC servers formed a single IRC network, to which new servers could join without restriction, but this was soon abused by people who set up servers to sabotage other users, channels, or servers. In August 1990, the server eris.berkeley.edu remained the only one to allow anyone to connect to the servers.

, introduced a new "Q-line" into their server configurations, to "quarantine" themselves away from eris by disconnecting from any subset of the IRC network as soon as they saw eris there.

For a few days, the entire IRC network suffered frequent netsplit

In computer networking, specifically Internet Relay Chat , netsplit is the disconnection of a given node from the previously established network or between two nodes. As an IRC network is an undirected acyclic graph, a split between any two nodes splits the entire network into two pieces.Consider...

s, but eventually the majority of servers added the Q-line and effectively created a new separate IRC net called EFnet (Eris-Free Network); the remaining servers who stayed connected to eris (and thus were no longer able to connect to EFnet servers) were called A-net (Anarchy Network). A-net soon vanished, leaving EFnet as the only IRC network.

Continuing problems with performance and abuse eventually led to the rise of another major IRC network, Undernet

In July 1996, disagreement on policy caused EFnet to break in two: the slightly larger European half (including Australia and Japan) formed IRCnet

February 2009 saw the introduction of a new CHANFIX module called OPME, a mechanism for EFnet Admins to use to restore ops in an opless channel. It provides a much cleaner alternative to masskill, which was unnecessarily invasive and disruptive to the network.

Later in 2009, some major IRC servers were delinked: irc.vel.net, irc.dks.ca, irc.pte.hu, EFnet's only UK server efnet.demon.co.uk, and EFnet's only UK hub hub.uk, which were sponsored by Demon Internet

In the last few years EFnet has lost a growing number of it's original servers [2011].

Characteristics

EFnet is probably the least "unified" IRC network, with large variations in rules and policy between different servers as well as the two major regions (EU

EFnet has always been known for its lack of IRC services that other IRC networks support (such as NickServ and ChanServ, although it had a NickServ until April 8, 1994). Instead, the CHANFIX service was introduced to fix "opless" channels.

A vast majority of servers on EFnet run ircd-ratbox. A handful run ircd-hybrid, and one runs csircd.

EFnet's channel operators are generally free to run their channels however they see fit without the intervention of IRCops. IRCops are primarily there to handle network and server related issues, and rarely get involved with channel level issues.
