connect <new server> [[<port>] <existing server>]
This command is used to connect servers to the irc network. It must be given at least one argument, the name of a remote server to connect to the network. If only one server is given, it is connected to the client's server on the default port. Alternately, a specific server and port may be specified.
Wildcards are permitted in the server names, if they are unambiguous.
To connect irc.foo.com to your current server:
To connect irc.foo.com with irc.bar.com on port 31337 of irc.bar.com:
/connect irc.foo.com 31337 irc.bar.com
This command is limited to irc operators, for reasons that should be obvious. Further, both servers must have appropriate C: and N: lines in their configuration to allow the connection.
