Oper block

In oper blocks you define all the IRC Operators accounts. Once defined you use the /OPER command on IRC to become IRCOp.

Syntax
oper { /* Required items: */ mask ; password ; class ; operclass ; /* Optional items to further limit who can /OPER */ require-modes maxlogins ; /* Optional items to define what will be set upon successful /OPER */ vhost ; swhois ; modes ; snomask ; };

name
The name in the oper name { block defines which name to use in the OPER command on IRC (/OPER name password). This name is case sensitive!

Most people use their nick name here. You can use latin characters (A-Z a-z), numbers and _-[]. Do not use special characters like ö (as in Björn) or Arabic/Greek/etc. Such characters may cause you problems with /OPER'ing due to character set differences.

password
The password item defines the password to use. Passwords are case sensitive. Instead of using a plaintext password here, we highly recommend you to use Hashed passwords or SSL certificate fingerprints, see Authentication types.

mask
The mask defines from which host/IP this oper block may be used, this can be used for increased security. Set this to mask *; if you want to permit any IP. You may also use multiple masks, in which case the syntax becomes like: mask { 1.2.3.*; 55.66.*; 11.22.*; *.co.uk; };

class
After a successful /OPER attempt the user will be put in the class you specify here. It's recommended to use a special class you created for opers (eg: class opers;) that typically has higher flood limits than ordinary users.

operclass
This defines which Operclass block to use. The operclass block configures which privileges this IRCOp will have (which IRCOp commands you may use, etc..).

require-modes
This lets one specify modes (such as 'z') that a user must have acquired before being allowed to OPER. This can be used, for example, to require opers to be on secure connections (user mode +z) before being able to become operators.

maxlogins
This allows you to restrict the number of concurrent oper logins from this host, for example if you set it to 1 then only 1 person can be oper'ed via this block at any time.

vhost
This hostname (virtual host) will be set after you successfully oper up.

swhois
Allows you to add one or more extra lines to the /WHOIS information for this oper. For example: swhois "a Network Administrator";

modes
Set these user modes after successful oper up.

snomask
By default an IRCOp gets the Snomasks from set::snomask-on-oper. You can use this oper::snomask to specify a different set of snomasks. See Snomasks for a full list.

Example
oper bobsmith { class opers; mask { smithco.com; *.somedialupisp.com; }; password "f00"; operclass netadmin; swhois "a Network Administrator"; snomask cFfkoSsqNG; };

Some little information about OperOverride
OperOverride are things like: joining a +ikl channel and going through bans, op'ing yourself in a channel, etc. See the OperOverride article for all information on this.
