How many irc connections are you allowed

Use commas to specify more than one channel, for example:. You are now ready to connect to an IRC server. Click the Connect button and wait until you are connected. Select the new server from the list, but this time use Connect in a New Tab to create a separate tab for this new server. If you forget to do this, you will disconnect from your current server and connect to the new one in the existing tab. To do this, select the network from your server list and check Auto Connect at Startup.

If you do this, you may also want to check the No Server List at Startup option. For example:. In most cases, you will connect to a round-robin server, which will automatically pick a server and direct you there. If you find a particular server that behaves more stably that any of the others, you can set the server of your choice at the top of the server list for your network.

You can then click the Add button to add another one in case your preferred one is down. If you want to use a different nickname on a certain network, select the network in the server list and uncheck Use Global User Info.

You can then fill in a nickname, username, and real name for this server. The XChat interface can be customized in a number of ways. The first few are simple visibility options. Right-click a blank area in the IRC window, and you can select on and off options for the menu bar, topic bar, mode buttons, and user list buttons. Select whatever combination makes you happy. There are far too many preferences to detail here, so you may like to play around with them and see what you can achieve.

Here are some items worth noting:. Besides setting the colors and fonts for chatting, the checkboxes also affect the way you see your chat. Try turning on Nick Coloring or Timestamp, for example, or perhaps you prefer to turn off the Indented Nicknames feature?

The Nick Completion Suffix is used for two things. First, if you type a partial nickname at the start of the line and press the Tab key, XChat will attempt to complete the nickname and add this suffix to it.

Second, if you check Automatic Nick Completion , whenever you type a partial nickname followed by this suffix, XChat will replace it with the full nickname. Here you can also change the user list sort order or set a double-click command. Tabs are used to store channel and server windows. This lets you adjust the layout of your screen and how you use tabs.

These settings let you change the colors of your text box and user list. Here you can set the default messages for when you quit IRC, leave a channel, or go away. If you wish to log conversations for reference or for generating IRC statistics , you can check Enable Logging of Conversations here. This lets you change where XChat places incoming files or adjust the speed at which the files are transferred. If you are behind a firewall, you can also restrict the DCC ports used when you send files.

Here are some neat hacks you can do with XChat:. If you want to remove a tab and give it its own window, press Ctrl - I. Press them again to place it back as a tab.

You can also right-click on the tab and select Detach Tab. Right-click on a tab, and choose the Channel Name submenu. Many consider them to be garish and ugly. However, if you find you simply must use color codes:. Typing this as part of a message will cause it to be interpreted as a color code.

Under Unix and Linux systems, you can display output from any command that you run. This, however, is displayed in the window and not sent to the IRC server. This will print the accesses to your web server as they occur, if you really need to. Be careful what programs you call. An auto-replace is a string of text that gets automatically replaced with another. Setting up a user command in XChat is simple. Click Add New , and choose a name. Then you can type in your command.

You can click the Help button for a list of substitution strings. Commands can be multiple action as well. They will be performed in the order listed, for example:.

If you have other system information scripts, you can call them instead of, or in addition to, the ones found here. It is inadvisable to call exec multiple times in a row, because XChat can be running only one process per text box at any time. You can change the message format and colors of any event in IRC or assign a custom sound to play.

Then find the event you want to change. For example, to have a sound play whenever the topic changes, you would select Topic Change and enter a path to a sound file. To do this, modify the Channel Message format string like so:. Assuming you have the user list buttons turned on right-click empty space, then select User List Buttons , you can add buttons to this list or to the user list pop up which appears when you right-click a username in the chat window or the user list.

The syntax for such a command is the same as for a user command, except the name of the command is used for the label of the button or the menu item, and there are more substitutions available. Use existing entries as guidelines if you want to. Care to set up some useful information for CTCP? In general, use the same guidelines as the other lists and see Help for useful substitutions. Note, however, that the proper way to send a reply is:.

This will ensure maximum compatibility with other clients. Check them out for your favorite features. There is no shortage of IRC clients for Macintosh users. ChatZilla [Hack 4] , the truly outstanding IRC client integrated into Mozilla, is popular among Mac users and can also be used on other operating systems. Non-Mozilla users have many alternatives, too. However, because the features of IRC are different than the set for other chat applications, IRC users may find themselves frustrated with these programs.

The server-channel model is not clearly supported, and sending standard IRC commands is difficult when they are not all fully supported.

It sports a rather iChat-like look-and-feel Figure with just about everything accessible through an intuitive set of buttons and switches and drag-and-drop support throughout. A Favorites list holds your best buddies and preferred channels so you can just log on and click your way to conversation.

A Recent Channels and Users list helps you find that person you were chatting with yesterday or where you had that fabulous conversation last week. Or just set things up so you automatically log in and join your various discussion channels automatically. When X-Chat launches, you are prompted to enter nicknames and personal information and to choose a server in the Server List window see Figure A list of networks is provided by default, and you have the option to add to the list.

Once nicks and server are selected, clicking Connect will connect and open a server window. X-Chat Aqua can use a tab- or window-based view of channels and servers. The default setup puts each channel in a tab at the bottom of the window as it is joined.

Examples are help, windows, irchelp, and mirc. You can also do this for smaller numbers. Even very crowded channels can be silent, so if you join a channel and don't hear much talking, it may be because you joined, but just because the people on that channel are doing other things.

Some networks support registered nicknames. This means that they allow you to set a password on a nickname so that you own it. Only the person who knows that password will be able to use it.

There are, literally, millions of possible channel names, so if someone is on your usual channel, just go to another. The answer to this question is the current channel operators and them alone. Given the dynamic nature of channels, channel operators do not need to have a reason to kick you off. They decide what goes on in the channel. It is their channel. Complaining either to IRC operators or to the system administrators about being kicked or banned from a channel will not result in action.

IRC operators do not meddle with channel politics - that's the job of channel operators. If you should get banned or kicked from a channel, you are always free to start your own channel and decide what is appropriate content there. Imagine channels as houses. The owner of the house can decide to share ownership with someone else and can decide to prevent any individual from entering his house.

In your own house, you call the shots. Feel free to create your own channel, and set up your own rules for it. Channel operators are the owners of their respective channels.

If you are a channel operator, keep this in mind when giving out channel operator powers. Do not give out channel operator status to everyone.

This causes the possibility of mass-kicking or otherwise harassing by unknown ops and the channel can be left without any channel operators. However, always make sure to give ops to enough people so that all of the channel operators don't unexpectedly disappear and leave the channel without any operators.

If no ops are on your channel you have one option. You can ask everyone to leave and rejoin the channel. This is a good way to get channel operator status back. This does not work on large channels or ones with bots, for obvious reasons. On some networks, you can register a channel so that you own it and can maintain control over it as far as who gets channel operator status and how that privilege is governed.

A "bot" is short for "robot". It is normally a script run from a client or a separate program in perl, C, and sometimes more obscure languages. Bots are normally not needed on IRC. A bot generally tries to "protect" a channel from takeovers or performs other functions. It is important to know that some IRC servers ban all bots. Some bots provide useful features and can be entertaining.

Contrary to these bots, you will find many bots performing useless 'carekeeping' of channels, harassing and boring people and sometimes created with the sole purpose to produce garbage. You can imagine that these bots are disliked by the IRC community. In this context it is good to advise you to never, ever take bot code,.

If you feel you just have to run a bot, at least learn the programming. Some networks support a nickname registration service called NickServ. This allows users to register and own nicknames. Some networks support a channel registration service called ChanServ. This allows users to register and own channels. If you use the LIST command, the server generates a list of all channels and quickly sends that list to you. But, because the data throughput is finite, the entire output of the LIST command is queued in a buffer on the server.

At some point that buffer is overrun, and the server, detecting this 'reached maxsendq' , disconnects you. This mechanism is designed to disconnect people who generate more characters per second than any 'normal' person uses for normal conversations. It is a server protection mechanism, but unfortunately the server does not recognize that the data stream you caused is simply the result of your harmless LIST command, and disconnects you.

In most IRC clients, you can filter the channels list to show only channels with a minimum and a maximum number of people. You can also specify a text string so that your client will only list channels with that string in their name or topic. However, for the problem described, this may not always help. Some servers always send you the entire channels list and your client takes care of the filtering.

So, asking for a partial list to prevent you from disconnecting won't make any difference. It is unfortunate, but there is nothing you can do to prevent this from happening.

It is just one of the all-too-many IRC oddities. Try using some other server, as many are more forgiving. Netsplits are unfortunately a routine part of IRC life. The above message means that NickName, who was on a channel with you, was on a different server from you and this server split off from the part of the net you are on.

A B C. Let's say that you are on server D, and server A splits from server B. In this case, you will see all users on the servers B, C and E, "sign off". Note that netsplits are all from the point of view of the user. After a netsplit rejoins people might ask where you went -- because from their perspective, you split off. The only thing you can do during a netsplit is wait for the net to merge itself. Changing your server during a netsplit is a Bad Idea, because you are likely to have your nickname collided.

A "split" often occurs due to faults in the underlying physical network. It can also occur due to other reasons, such as if the machine on which the IRC server runs crashes, or if it is too overloaded to handle connections as happens on bigger nets, or if an IRC operator willfully disrupts the connection between two servers to achieve better routing server - server connections. After a netsplit, a net-join begins and on both halves of the merging network, and people that existed with the same nicknames can be killed.

This can happen frequently with popular nicknames. This phenomena is called a Nick Collision. As soon as a Nick Collision is detected in general both persons involved will be disconnected killed from their IRC servers. Nick Collisions can be caused on purpose by people who just want to harass others or try to take over their channel.

In general, this behavior is considered very abusive and can easily lead to a K-line. After a netsplit, during the net-join process, servers on both sides of the split try to update all kinds of information they may have missed. New users, their nicknames, the channels they are on and most of the channel settings are exchanged. The servers involved in the split will also make sure on both sides of the split on all channels the same channel operators are set. This process is called server-opping.

Server-ops show like:. Server-ops are famous for its use in malicious behaviour. People can use net-splits to get operator status on a channel on one side of the split and on the moment of net-join de-op the rightful channel operators. The Undernet has an improved server-server protocol which prevents server-op abuse as well as channel desynchs and intentional nick collides. An ident server is normally a kind of nameserver, usually on large organizational or corporate networks, that guarantee your Identity.

Since many users connect to IRC from their home computers, they sometimes have to run their own ident server. Some IRC clients come with such a server built into them to help you.

IRC servers can do perform an ident request to your ident server and expect a standard response. More and more IRC servers require you to be identified in some way, and they will disconnect you if you are not identified. Channels can have additional constraints, which can be set by the MODE command.

To understand this, recall that the first person that joined a channel effectively creates it and is, at least initially, in charge of the channel.

They become a Channel Operator or chanop or 'op'. They can set constraints on the channel and make other people chanops as they wish. The command that allows channel operators to change channel modes, or any user to change their personal mode is:. Channels can be moderated, secret, private, with a limited number of users, anonymous, invite-only, topic-limited, with a list of banned users The MODE command also allows you to modify your personal parameters, your "user mode".

You can't do a -r mode change. Anyone can notice a public channel, see its users and join the conversation. In a list of channels you can see a public channel's topic. When someone is on a public channel, he can be easily found by all other users as long as his personal user mode is not set to invisible see below.

People can see you are on a private channel somewhere, but they can never find out on -which- private channel you are unless they search all private channels by brute force. SECRET channels do not show up in a channels list and you cannot find out its topic unless you join it. If you are on a secret channel, someone who is not on the same channel can't see that you are there, regardless what your personal user mode is set to.

Your name does not show up in a names list of people on IRC if you are on secret channels only. But you can chat normally.

Try to choose a server that is close to you. As a rule of thumb, servers that are close geographically are also close network-wise which is what matters but this rule of thumb is not always true. If in doubt, ask some people from the same area what servers they use. The larger the distance to the server, the larger the chance it refuses you or gives you only restricted access. Depending on the IRC client you are using, or even the type of operating system you are on, you may come across other commands or features that may or may not apply to your situation.

Oikarinen and D. This RFC is available here. On IRC, you will find several channels intended to help you with simple as well as more difficult problems. Try joining those channels for help. You can also try joining irchelp, which is a common help channel. Please remember, we are all volunteers on these channels, giving our own time to help other users. I am fully aware that a lot of the information found in this file can be found in the same or similar form in several other IRC related FAQ's already.

I have tried to combine the best of worlds by focusing on the most common issues and questions. I hope I was successful. All information contained in this file is based on the work and time various people invested by answering questions in the Usenet alt.

Mirashi for the time and effort they spend on their IRC ambassador job! Of course I am the only one responsible for all omissions and mistakes in this file, but I hide behind the usual disclaimers What is IRC? How does IRC work? What does a client do? What is the purpose of a server? How do I get on IRC? This field should refer to an existing class.

Connections classes are usefull to limit the number of users allowed on the server. This field contains flags of an I:line; flags are one character in size, can be combined and their order does not matter. R - restricted D - restricted, when client has no reverse DNS I - restricted, when client has no ident.

E - client is exempted from K: lines N - do not show resolved hostname bans still match F - fall-through to next I:line if password not matched.

If a match is found, the client is accepted. The matching field is used to set the name of the client: for example, if the client matches the TARGET Host Addr field, it will show on IRC with a numerical address even if this address is resolvable. For example, if you were installing IRC on tolsun. Allow clients from a machine with that IP number to connect. Numeric match is enough, name is not required anymore. This is the easiest way, but it also allows people to for example dump files to your server, or connect or how many open sockets per process your OS allows clients to your machine and take your network ports.

Of course the same things can be done by simply telnetting to your machine's SMTP port for example. If the host name is known, is it used as address for these clients. Local operator has basically the same rights except global operator with some restrictions.

This means that you should be logged into this host when you ask for the priviliges. The class field should refer to an existing class preferably having a lower number than that for the relevant I-line and determines the maximum number of simultaneous uses of the O-line allowable through the max. Remove an errant user from IRC on your site.

Introduction Obviously it is hoped that you wouldn't have to use this command. In this field you specify the Hostname or the IP address Single IP, Wildcard notation or bitmask notation that the user is connecting from. If you specify an IP address, IP mask, or an IP bitmask, it will match clients connecting from the matching addresses, no matter if they resolve or not. You may also specify intervals during the line should be active, see examples below.

This field will be matched against the ident server reply. Users get kicked off if they're already signed on when the line becomes active they'll get a warning 5 minutes before. Note that this requires ircd to be compiled with proper define! For my example let us assume I am on the machine "rieska. If irc.

This is because of two main reasons: to save your server from causing extra load and delays to users to save internet from extra network traffic remember the old rwho program with traffic problems when the number of machines increased. This field tells the IRC program which option is being configured. Specifies the host name or IP address of the machine to connect to.

The password of the other host. A password must always be present for the line to be recognized. The full hostname of the target machine. If you were connecting to nic. The port field can contain 2 ports, separated by a.

In this case, the first port is used when auto-connecting, the second port is used for the UDP pings to the targer server. The class field should refer to an existing class and determines the maximum number of simultaneous uses of the C-line allowable through the max. As of the 2. Some examples: C:nic. Your machine will connect to this host to port You will connect to Internet Port on this host.

So as we enter these entries into the file they must be done in reverse order of how we could want to connect to them. To explain the usage of wildcard domains we take an example of such:. Imagine servers in Germany, it would be incredible waste of network bandwidth to broadcast all of them to all servers around the world. In this case the wildcard count is 1, because only one word tolsun is replaced by a wildcard. I advise you to not to use wildcard servers before you know for sure how they are used, they are mostly beneficial for backbones of countries and other large areas with common domain.

Introduction D lines were implemented to give server administrators more control on how auto connections are done. This will most likely only be useful for big networks which have complex configurations.

If this field contains a class number, it will match if any server in that class is currently present on the network. Note that this can be true for any server, even the ones not directly connected. This field is used to match against the class to which belong the servers for which an autoconnect is set. If a server is only going to supply its own name ie act as a solitary leaf then no H-line is required for, else a H-line must be added.

SIDs of all servers that are allowed via this H-line must match the mask given in this field. This field is used to match exactly against a server name, wildcards being treated as literal characters. Introduction To stop servers which should only act as leaves from hubs becoming hubs accidently, the L line was introduced so that hubs can be aware of which servers should and shouldnt be treated as leaves.
