If you own an IRC server, and would like to enable people to access it from Mibbit without issues, it's simple to get set up.

First of all, anyone who uses Mibbit connects from one of our four IP address to your IRC server. This needs to be handled by the IRC server. The default setup for most IRC servers is to only allow 3 or so connections from any single IP, which means that only 3 .. 12 Mibbitians would be able to connect to the server. There are two solutions to this: WebIRC (best) or a trust/session increase.

Contents

Mibbit IP addresses

IP rDNS
207.192.75.252 ircip1.mibbit.com
64.62.228.82 ircip2.mibbit.com
78.129.202.38 ircip3.mibbit.com
109.169.29.95 ircip4.mibbit.com
Advanced: If you would like to automatically generate your own IRCd configurations using a script of some form either for remote include or other method depending on your IRCd you will be able to find all current Mibbit WEBIRC IPs in the ircip.mibbit.com round robin host name. If you don't know what this means, don't ask, just skip it.

WebIRC/CGI:IRC Blocks

The webirc protocol allows Mibbit to send over the users real IP address and hostname to the IRC server. This means that cloaks, and bans, and all other hostname/IP based things work exactly as they should. When you whois the user, it'll look like they are connecting directly from their own IP, and not through Mibbit. This is also known as a cgiirc{} block on some servers. This is the best method of having Mibbit connect to your network seamlessly.

If you wish to set up a Web:IRC configuration for Mibbit, please follow the following steps.

  1. Choose a WebIRC password.
    • This password should be between 6-20 alphanumeric characters. Please don't use special characters.
  2. Configure your servers. How to do so is listed below for each server type.
    • IP addresses are in the section above for reference and in each IRCd specific section below.
    • Please have your settings saved and rehashed
  3. Gather the following information so that you may supply it in the following step.
    • Network name
      • Will be shown in the server tab, so keep it short but meaningful. For irc.example.net could be "Example Net"
    • A list of all DNS entries that point to your network.
      • e.g., irc.blah.net, blah.com, oldname.com etc.
      • In the case that not all servers in your network are set up with WebIRC, a list of the servers with WebIRC enabled.
    • Preferred connect server or round robin and the port number (if not 6667)
      • e.g., irc.blah.net:1234 (will be used by the main client)
    • Server admin's Email address
    • Server admin's nickname on server
    • WebIRC password (maximum length 20 characters)
    • Public (yes/no)
      • Only say yes if both:
        • you have more than 50 users. No, services and bots do not count. IRC OPs do not count either.
        • you want to see your server listed in the main client's Home > IRC: dropdown list.
      • If there are reports that the Mibbit client cannot connect, once the entry is set up, then the "public" entry will be removed.
    • IRCd version
    • General description of the network
      • A tag such as "Gaming", "Support", "Politics", ect.
  4. Send an email to ircstaff@mibbit.com or contact a staff member on IRC.Mibbit.net in the #help channel (if you are lucky to find an active ircop):
    • Staff member (ircop) via IRC
      • Make sure the person is a staff member (/whois). Staff members are listed in the /motd.
      • Ask if anybody is available to add a WebIRC entry.
      • If a staff member responds in the positive, send them the information gathered above via a private message.
      • Pastebin your information to save time.
      • If not, send an email. You can send an email without trying on IRC, but it can be faster to set up through IRC.
    • Send an email.
      • The subject should include "WebIRC" and your network name. For example, "Example Net: WebIRC Configuration".
      • Send the email to ircstaff@mibbit.com.
      • Include all of the gathered information.
      • Most emails are processed within 24 hours.
  5. Once your information is added to our database, we will give you a confirmation message, whether through IRC or email.


Unrealircd

Example UnrealIRCd cgiirc block setup/configuration (Requires UnrealIRCd 3.2.5 or higher):

// Datacenter one :
cgiirc {
       type webirc;
       hostname 64.62.228.82;
       password <password>; // no <> brackets around password!
};
// Datacenter two:
cgiirc {
       type webirc;
       hostname 207.192.75.252;
       password <password>; // same password as above!
};
// Datacenter three:
cgiirc {
       type webirc;
       hostname 78.129.202.38;
       password <password>; // same password as above!
};
// Datacenter four:
cgiirc {
       type webirc;
       hostname 109.169.29.95;
       password <password>; // same password as above!
};

Note: UnrealIRCd versions between 3.2.5 to 3.2.7 have cgiirc block bugs in IPv6 compiles of UnrealIRCd, Patch available here, this issue however is resolved in version 3.2.8 and up.

Read the CGI:IRC Block documentation for more information on cgiirc blocks.

After updating your configuration please rehash and let us know the information requested above.

Inspircd

These are instructions for how to configure an InspIRCd installation.

1.) Locate the cgiirc module in the modules.conf (or inspircd.conf) called m_cgiirc.so
Look for
<module name="m_cgiirc.so">
and uncomment it.

2.) Locate the cgihost tag below and configure as follows:

  • Choose type as Webirc
  • In the password attribute, replace <password> with the password you chose.
  • In the mask attribute, enter our IP addresses (64.62.228.82, 207.192.75.252, 78.129.202.38, 109.169.29.95)
    Note: In some cases its been reported that connection from mibbit users were not resolved to the correct address. In some cases this can be fixed by setting the mask to "*". Try it only as last resort.
Your cgihost should look like this:
<cgihost type="webirc" password="<password>" mask="64.62.228.82">
<cgihost type="webirc" password="<password>" mask="207.192.75.252">
<cgihost type="webirc" password="<password>" mask="78.129.202.38">
<cgihost type="webirc" password="<password>" mask="109.169.29.95">

NO <> brackets around password!

3.) Locate your connection block and add an additional block as follows (Inspircd 1.*):

<connect 
   allow="64.62.228.82" 
   allow="207.192.75.252"
   allow="78.129.202.38" 
   allow="109.169.29.95" 
   timeout="60" 
   flood="10" 
   pingfreq="120"
   threshold="5" 
   sendq="131074"
   recvq="4096"
   globalmax="30"
   localmax="30"
   port="6667">

Inspircd 2.0+ seems to require separate <connect allow="...> lines, see their docs.

Warning: if all mibbitians get the same Mibbit@ircip*.mibbit.com (or the obfuscated version) as ident@host after the changes, you need to reload the cgiirc module (after every change, even if they claim the bug was fixed). A password mismatch results in the same "bad host" issue. No "invalid password" error message is sent to us! You might see something like "user tried to use WEBIRC, but didn't match any configured webirc blocks" in your server logs.

The major difference from your normal <connect> block should be the allow parameter and the globalmax and localmax. The reason for these changes is so that the server does not identify several users of mibbit as coming from the same IP and then raises a session exceeded error.

If you are having problems getting the module to work, try rehashing and reloading the module after configuration changes. The easiest way to do this is by rehashing, then issuing the command "/reloadmodule m_cgiirc.so". Sometimes only a server restart helps.

For more information see InspIRCd m_cgiirc documentation

Then let us know the information requested above.

Nefarious

If F:CRYPT_OPER_PASSWORD is set to TRUE (default) you will need to use "/mkpasswd <password>" to crypt the password before adding it to the W:Line. If F:CRYPT_OPER_PASSWORD is set to FALSE then you will have to put the password in the W:Line in plain text.

To check the version and revision use "/version" or "/quote version" depending on your IRC client and then look for:

u2.10.11.07+Nefarious(<version>)+[<revision> <date>].

Sample config for Nefarious 1.3:

WebIRC {
  mask = "*@64.62.228.82";
  pass = "<password>";
  flags = "s";
  ident = "mibbit";
  desc = "Mibbit";
};
WebIRC {
  mask = "*@207.192.75.252";
  pass = "<password>";
  flags = "s";
  ident = "mibbit";
  desc = "Mibbit";
};
WebIRC {
  mask = "*@78.129.202.38";
  pass = "<password>";
  flags = "s";
  ident = "mibbit";
  desc = "Mibbit";
};
WebIRC {
  mask = "*@109.169.29.95";
  pass = "<password>";
  flags = "s";
  ident = "mibbit";
  desc = "Mibbit";
};

Sample config for Nefarious 2.0:

WebIRC {
 host = "*@64.62.228.82";
 password = "<password>";
 ident = "mibbit";
 description = "Mibbit";
};
WebIRC {
 host = "*@207.192.75.252";
 password = "<password>";
 ident = "mibbit";
 description = "Mibbit";
};
WebIRC {
 host = "*@78.129.202.38";
 password = "<password>";
 ident = "mibbit";
 description = "Mibbit";
};
WebIRC {
 host = "*@109.169.29.95";
 password = "<password>";
 ident = "mibbit";
 description = "Mibbit";
};

mask = "*@*.mibbit.com"; may be neccessary (encrypted passwords could result in a "WEBIRC Password invalid for your host" error).

Then let us know the information requested above.

Charybdis

(tested with Charybdis-3.1.0)

# Enable the webirc module:
loadmodule "extensions/m_webirc.so";
# Place it were it belongs.
auth {
       # Mibbit one      
       user = "*@64.62.228.82";
       # Mibbit two
       user = "*@207.192.75.252";
       # Mibbit three        
       user = "*@78.129.202.38";
       # Mibbit four        
       user = "*@109.169.29.95";
       # Place here your password (default: unencrypted).
       password = "<password>"; 
       # The line below makes care that
       # Charybdis understands this is the webirc module.
       spoof = "webirc.";
       # The class.
       class = "users";
};
# NO <> brackets around password!

Always check your config with the following command (path to your charybdis installation)/bin/ircd -conftest to make sure it loads the module correctly and your config is intact. Anyways, if that succeeds it shows: notice: loading module extensions/m_webirc.so ...

Then let us know the information requested above.

RatboxIRCd

Example RatboxIRCd cgiirc block setup/configuration (Requires RatboxIRCd 3.0.x or higher):

// For all datacenters :
auth {
        user = "cgiirc@64.62.228.82";     
        user = "cgiirc@207.192.75.252";     
        user = "cgiirc@78.129.202.38";     
        user = "cgiirc@109.169.29.95";     
        password = "<password>";
        spoof = "webirc.";
        class = "users";
};
// NO <> brackets around password!
// The above needs to be before the following existing lines in your config
auth {
   user = "*@*";
   class = "users";
};

Note: The m_webirc.c module is not installed by default. Compile the m_webirc.c module, then loadmod contribs/m_webirc.so. See the output similar to *** Notice -- Module m_webirc.so [version: $Revision: 26401 $; MAPI version: 1] loaded at 0x29e3c580.

Then let us know the information requested above.

Hybrid

This section applies to ircd-hybrid-7.2.3


Back-story & credit:

While attempting to support webirc for ircd-hybrid I discovered that the module linked by this page no longer compiled properly for the current stable release (as of this writing 7.2.3). After a bit of time with Google I discovered this article.

  • ircd-hybrid Initial help by The_Spider (irc.smoothnet.org)


To compile:

  • Download the m_webirc.c module and place it in the contrib folder.
  • Modify 'Makefile.in' (also located in the contrib folder) by adding the line between any line at 34-48:
 m_webirc.c \
  • Follow normal installation instructions.(Don't forget to 'make install' in the contrib folder after you configure the main branch. Otherwise none of the modules there will be compiled and installed)


Configuration:

Modify the proper sections of your ircd.conf to reflect the following:

// For all datacenters :
 auth {
   user = "*@207.192.75.252";
   user = "*@64.62.228.82";
   user = "*@78.129.202.38";
   user = "*@109.169.29.95";
   password = "<password>";
   spoof = "webirc.";
   class = "users";
 };
// NO <> brackets around password!
// The above needs to be before the following existing lines in your config
auth {
   user = "*@*";
   class = "users";
};
 module = "m_webirc.so";
  • Remove an existing example gecos ban
    • This prevents connection after a successful webirc conversion, generating a "Bad user info" ban.
 gecos {
   name = "*http*";
   reason = "Spambot";
 };

As of posting, there is concern that host cloaking can override this module and render the host back to the original Mibbit IP. This can be seen as the user is presented with a clear message that webirc conversion was successful, yet /whois shows the host reverted. Disabling host cloaking does prove that the webirc process is working. This is not a recommendation to disable host cloaking. This was seen on hybrid-7.2.3+plexus-3.0.0(20070716_2-509

Other

The protocol is pretty simple. The first command sent to the server is:

WEBIRC <password> cgiirc <hostname> <ip>

(NO <> brackets around password!)

The server then uses the hostname and ip for that connection.

Trust/session limit increase

If webirc is unavailable, mibbit sends over the users IP address and hostname. In the ident reply, we send the users IP address in hex form. We also set the users realname to be their hostname. If you use this method, you can ban individuals on their username. You just need to increase the connection limit for the Mibbit IP, and please remember NOT to k-line/ban the whole of *.mibbit.com . Ban individuals instead.

Our IPs are 64.62.228.82, 207.192.75.252, 78.129.202.38, 109.169.29.95.
