The precise terms and conditions for copying, distribution and modification follow.

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0. This License applies to any program - or other work which contains a notice placed by the copyright holder -saying it may be distributed under the terms of this General Public License. - The "Program", below, refers to any such program or work, and a "work -based on the Program" means either the Program or any derivative work under -copyright law: that is to say, a work containing the Program or a portion -of it, either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in the -term "modification".) Each licensee is addressed as "you".

Activities other than copying, distribution and modification - are not covered by this License; they are outside its scope. The act -of running the Program is not restricted, and the output from the Program - is covered only if its contents constitute a work based on the Program -(independent of having been made by running the Program). Whether that is -true depends on what the Program does.

1. You may copy and distribute verbatim - copies of the Program's source code as you receive it, in any medium, -provided that you conspicuously and appropriately publish on each copy -an appropriate copyright notice and disclaimer of warranty; keep intact -all the notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License along + +

2. You may modify your copy or copies - of the Program or any portion of it, thus forming a work based on the -Program, and copy and distribute such modifications or work under the -terms of Section 1 above, provided that you also meet all of these conditions: + +

2. You may modify your copy or copies + of the Program or any portion of it, thus forming a work based on the +Program, and copy and distribute such modifications or work under the terms +of Section 1 above, provided that you also meet all of these conditions:

Thus, it is not the intent of this section to claim rights +or contest your rights to work written entirely by you; rather, the intent +is to exercise the right to control the distribution of derivative or collective +works based on the Program.

In addition, mere aggregation of another work not based + on the Program with the Program (or with a work based on the Program) +on a volume of a storage or distribution medium does not bring the other work under the scope of this License.

3. You may copy and distribute the - Program (or a work based on it, under Section 2) in object code or executable - form under the terms of Sections 1 and 2 above provided that you also -do one of the following: -

If distribution of executable or object code is made + by offering access to copy from a designated place, then offering equivalent + access to copy the source code from the same place counts as distribution + of the source code, even though third parties are not compelled to copy the source along with the object code.

4. You may not copy, modify, sublicense, - or distribute the Program except as expressly provided under this License. - Any attempt otherwise to copy, modify, sublicense or distribute the -Program is void, and will automatically terminate your rights under this -License. However, parties who have received copies, or rights, from you -under this License will not have their licenses terminated so long as -such parties remain in full compliance.

5. You are not required to accept - this License, since you have not signed it. However, nothing else grants - you permission to modify or distribute the Program or its derivative -works. These actions are prohibited by law if you do not accept this -License. Therefore, by modifying or distributing the Program (or any work -based on the Program), you indicate your acceptance of this License to -do so, and all its terms and conditions for copying, distributing or modifying -the Program or works based on it.

6. Each time you redistribute the -Program (or any work based on the Program), the recipient automatically receives -a license from the original licensor to copy, distribute or modify the Program - subject to these terms and conditions. You may not impose any further - restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to this + +

7. If, as a consequence of a court - judgment or allegation of patent infringement or for any other reason -(not limited to patent issues), conditions are imposed on you (whether -by court order, agreement or otherwise) that contradict the conditions -of this License, they do not excuse you from the conditions of this License. - If you cannot distribute so as to satisfy simultaneously your obligations - under this License and any other pertinent obligations, then as a consequence - you may not distribute the Program at all. For example, if a patent license - would not permit royalty-free redistribution of the Program by all those - who receive copies directly or indirectly through you, then the only way - you could satisfy both it and this License would be to refrain entirely + +

If any portion of this section is held invalid or unenforceable - under any particular circumstance, the balance of the section is intended - to apply and the section as a whole is intended to apply in other circumstances. -

It is not the purpose of this section to induce you -to infringe any patents or other property right claims or to contest validity - of any such claims; this section has the sole purpose of protecting the - integrity of the free software distribution system, which is implemented - by public license practices. Many people have made generous contributions - to the wide range of software distributed through that system in reliance - on consistent application of that system; it is up to the author/donor -to decide if he or she is willing to distribute software through any other + +

This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.

8. If the distribution and/or use -of the Program is restricted in certain countries either by patents or by -copyrighted interfaces, the original copyright holder who places the Program -under this License may add an explicit geographical distribution limitation -excluding those countries, so that distribution is permitted only in or among - countries not thus excluded. In such case, this License incorporates the -limitation as if written in the body of this License.

Each version is given a distinguishing version number. - If the Program specifies a version number of this License which applies - to it and "any later version", you have the option of following the terms - and conditions either of that version or of any later version published - by the Free Software Foundation.

The BBS Login

- -

As with many Unix programs, Citadel wants to run under its own user ID. - Unlike other programs, however, this user ID will do double-duty as a public - login for your system if you are running a BBS. This account is typically - called "bbs" or "citadel" or something to that effect. You will tell Citadel - what the user-id of that account is, and when someone logs in under that -account, Citadel will prompt for a user name.

- -

The Citadel user should have a unique uid. The home directory should be - the one your Citadel installation resides in (in this example we will use - /usr/local/citadel) and the shell should be either "citadel" in that directory, - or a script that will start up citadel (you may wish to set up an external - text editor; see below). Example:

Example:

bbs::100:1:BBS Login:/usr/local/citadel:/usr/local/citadel/citadel

- -

When you run setup later, you will be required to tell it what the Citadel - user's numeric user ID is, so it knows what user to run as. If you create - an account called bbs, guest, or citadel, the - setup program will automatically pick up the user ID by default.

- -

For all other users in /etc/passwd, Citadel will automatically set up an -account using the full name (or 'gecos' in Unixspeak) of the user. It'll - also ignore any password you supply, because it uses the user's password -on the host system. This allows a 'single sign on' type of environment. Note - that this does have to be enabled at compile time -- it's the configure option - called --enable-autologin. Keep in mind that these users can use - *either* their Citadel login name or their login name on the host computer, - and their password on the host computer.

Bypassing the `login:` prompt

If you normally log in to your host system using some method other than - telnet (such as ssh), you might want the telnet service to go straight -to the Citadel BBS, instead of displaying the login: prompt first. - You can do this by having telnetd start citadel directly instead of /bin/login. - This is actually very simple to implement; all you need to do is make a -simple change to your inetd or xinetd configuration.

Please make sure you know what you're doing before you install this! -If you are going to put Citadel somewhere other than /usr/local/citadel - then change the directory name accordingly. If you know of any other local - peculiarities which need to be observed, edit the above configuration accordingly - as well. And, of course, if you're working remotely, make sure you can successfully - log in using SSH before you start changing your telnet configuration, otherwise - you could lock yourself out of your system (ask any networking specialist - about the dangers of "working inline" -- then pull up a chair and get a -fresh cup of coffee, because you're going to hear some war stories).

Basic site configuration

- -

Basic configuration of your Citadel system for Internet e-mail begins -with the .Aide System configuration Internet -command:

- -

-Lobby> .Aide System configuration Internet
-
-###                    Host or domain                     Record type
---- -------------------------------------------------- --------------------
-  1
-<A>dd <D>elete <S>ave <Q>uit  ->
-

- -

This is a "clean" setup. For a simple, standalone e-mail system -you simply have to enter the Add command:

- -

-<A>dd <D>elete <S>ave <Q>uit  -> Add
-
-Enter host name: schmeep.splorph.com
- (1) localhost       (Alias for this computer)
- (2) gateway domain  (Domain for all Citadel systems)
- (3) smart-host      (Forward all outbound mail to this host)
- (4) directory       (Consult the Global Address Book)
- (5) SpamAssassin    (Address of SpamAssassin server)
-
-Which one [1]:

- -

localhost: Basically what you're doing here is telling Citadel what -any aliases for -your machine are. If your machine were schmeep.splorph.com and you -also had a DNS entry set up for blah.com, you might want to enter '1' -and enter blah.com as your alias, so that e-mail sent to that -address won't bounce.

- -

Important tip: if your system is known by one name and only -one domain, you might not even need to do this at all. You will recall that -you entered your system's fully qualified domain name earlier when you went -through the .Aide System configuration General -command.

You will recall that +you entered your system's fully qualified domain name earlier when you went +through the .Aide System configuration General +command. The domain name you entered there is automatically considered by +Citadel to be a 'localhost' entry in your Internet mail configuration. It does not hurt to enter it in both locations, though.

- -

gateway domain: this is a simple way of mapping various Citadel -hosts in an Internet domain. For example, if you enter bar.com -as a gateway domain, then mail to users at foo.bar.com will be -forwarded to the host called foo on a Citadel network, mail to users -at kunst.bar.com will be delivered to the Citadel server called -kunst, etc. This feature has limited usefulness; if you are -operating a network of Citadel servers, it is more likely that you will -use the 'directory' feature, explained below.

- -

smart-host: Normally, Citadel sends outbound Internet e-mail -directly to its destination. This may not be appropriate for some sites; you -may require (due to local convention, security policy, or whatever) that all -outbound mail be sent to an SMTP relay or forwarder. To configure this -functionality, simply enter the domain name or IP address of your relay as -a 'smart-host' entry.

- -

directory: a domain for which you are participating in directory -services across any number of Citadel nodes. For example, if users who have -addresses in the domain citadel.org are spread out across multiple -Citadel servers on your network, then enter citadel.org as a -'directory' entry. For this to work, all Citadel servers participating -in directory service must carry and share the Global Address -Book> room.

- -

spamassassin: if you are running a -SpamAssassin service anywhere on -your local network, enter its name or IP address as a 'spamassassin' -entry. This may be (and, in fact, will usually be) 127.0.0.1 to -specify that the service is running on the same host computer as the -Citadel server.

+ +

Please install SpamAssassin as per its own documentation. You will want +to run SpamAssassin in client/server mode, where a spamd daemon +is always running on your computer. Citadel does not utilize the spamc client; instead, it implements SpamAssassin's protocol on its own.

- -

Connecting to a SpamAssassin service across a wide area network is -strongly discouraged. In order to determine whether an incoming e-mail is -spam, Citadel must feed the entire message to the SpamAssassin -service. Doing this over a wide area network would consume time and -bandwidth, which would affect performance.

- -

Citadel invokes the SpamAssassin service when incoming messages are -arriving via SMTP. Before a message is accepted, it is submitted to -SpamAssassin. If SpamAssassin determines that the message is spam, the -Citadel SMTP service rejects the message, causing a delivery failure -on the sending host. This is superior to software which files away spam -in a separate folder, because delivery failures will cause some spammers to -assume the address is invalid and remove it from their mailing lists.

- -

Now select Save and you are just about ready for -Internet e-mail.

As previously mentioned, Citadel contains its own SMTP, POP3, and IMAP services. Enabling them is simple.

- -

Check for the existance of a current MTA (sendmail, qmail, etc.) by -connecting to port 25 on your host. -If you see something similar to the following you're running an MTA -already and you'll need to shut it down:

- -

-smw @ pixel % telnet localhost 25
-Trying 127.0.0.1...
-Connected to localhost.
-Escape character is '^]'.
-220 pixel.citadel.org ESMTP Sendmail 8.9.3/8.9.3; Wed, 15 Mar 2000 19:00:53 -0500
-

- -

In the above example, we see that the host already has Sendmail listening -on port 25. Before Citadel can use port 25, Sendmail must be shut off. -Please consult the documentation for your operating system for instructions -on how to do this. (On a Red Hat Linux system, for example, you can run -the ntsysv utility, un-checking sendmail to disable it -at the next reboot; then, run service sendmail stop to shut off the -currently running service.)

- -

If you get a 'connection refused' message when you telnet to port 25 there's -nothing running and you should be able to continue. You might also want to -turn off POP (try the above test substituting 110 for 25) and IMAP (port 143) -and use Citadel's POP and IMAP services.

- -

Citadel will look for an existing pop/smtp server on startup. If they don't -exist (and you've configured them properly) then Citadel should -enable them at startup. You can check your logs to be sure, or you can -start the server from a shell and watch it load. It might look something -like this:

Using Citadel in conjunction with another MTA

Occationally it is not practical to remove a non-Citadel MTA on your -host system. For example, you might have multiple groups of users, some of -which are using Citadel and some of which are using a legacy Unix mail spool. -This type of configuration is discouraged, but a tool is provided to allow -it.

- -

The tool is called citmail and it is, quite simply, a local MDA -(Mail Delivery Agent) which you can configure into your MTA for final -delivery of incoming messages to Citadel users. A full discussion of the -finer points of complex Sendmail configurations is beyond the scope of this -document; however, you might want to visit -Pixel BBS where some -useful HOWTO documents are provided.

- -

For outbound mail, you can either allow Citadel to perform deliveries -directly (this won't affect your other mail system because outbound mail -doesn't tie up port 25) or enter 127.0.0.1 as your smart-host, which -will tell Citadel to forward all of its outbound mail to your other mail -system.

A full discussion of the finer points +of complex Sendmail configurations is beyond the scope of this document; +however, you might want to visit Pixel BBS where some useful +HOWTO documents are provided.
+ +
For outbound mail, you can either allow Citadel to perform deliveries directly +(this won't affect your other mail system because outbound mail doesn't tie +up port 25) or enter `127.0.0.1` as your smart-host, which will tell +Citadel to forward all of its outbound mail to your other mail system.

Building or joining +a Citadel network

+ + +

Overview

+ +

If you are running Citadel as a BBS or other forum type of application, +one way to 'keep the conversation going' is to share rooms with other Citadel +systems. In a shared room, a message posted to the room is automatically +propagated to every system on the network. It's kind of like a UseNet newsgroup, +but without the spam.

+ +

If you are using Citadel as the e-mail and groupware platform for a large +organization, you can use its networking features to build a large network +of Citadel servers which share content (think of rooms as public folders), +redistribute e-mail throughout the organization, and integrate the global +address book. It might make sense, for example, in a large corporation +to give each department or location its own Citadel server. Thanks +to Citadel's global address book features, you could still have all of the +users share a single e-mail domain.

+ +

Obviously, the first thing you have to do is find another Citadel to share +rooms with, and make arrangements with them. The following Citadels are +a good place to start:

+ +

UNCENSORED! - uncensored.citadel.org +
The Dog Pound II - dogpound2.citadel.org +
PixelBBS - pixel.citadel.org +

+ +

You don't have to be a part of the citadel.org domain to participate in +the public Citadel network, but the DNS service is provided free of charge +by the Citadel community if you wish to do this.

+ +

Conventions and etiquette +when connecting to the public Citadel network

+ +

Before we get into the technical nitty gritty, there are two points of +etiquette to keep in mind. The first thing to keep in mind is that the operator +of any particular Citadel may not be willing to share some of his/her rooms. + Some sites are proud to offer exclusive content in certain areas. Chances +are, if a room is already being shared on the network, it's available for +anyone to share; if not, it can't hurt to ask -- but take care not to demand +it of them. Ask if you may share the room instead of telling them that you +wish to share the room. When looking at a Known rooms list, +network rooms are the ones ending in parentheses instead of angle brackets. + For example, Gateway) would be a network room, Lobby> +would not.

+ +

The other point of etiquette to remember is that you should be making +the arrangements in advance, and then set it up. It is extremely rude to +simply begin networking with another Citadel, or unilaterally start sharing +a new room, without first obtaining permission from its operator. Always +ask first. Most Citadel operators are more than happy to network with you. + Also, if later on you decide to take your system down, please take the time +to notify the operators of any other Citadels you network with, so they can +unconfigure their end.

+ +

Getting ready to join +the network

+ +

Ok, first things first. On a Citadel room sharing network, the first +thing you need to know is your own system's node name. Presumably you set +this up during installation, but if you want to change it you can do so using +the .Aide Sysconfig General command:

+ +

Lobby> . Aide System configuration General
Node name [uncnsrd]:
Fully qualified domain name [uncensored.citadel.org]:
Human readable node name [Uncensored]:

+ +

The "node name" is important, it's how the network identifies messages +coming from your system. The "human readable node name" is simply a label; +it shows up in messages coming from your system. "Fully qualified domain +name" is your DNS name; it's used for routing messages on the Internet. In +the above example, the node name is "uncnsrd".

+ +

Defining neighbor nodes

+ +

The next thing you need to do is configure your neighbor node(s). You +need to do this for each node you network with. Let's say you wanted to +talk to a Citadel system called "frobozz". Use the .Aide Sysconfig +Network command:

+ +

Lobby> . Aide System configuration Network
###    Node            Secret                   Host or IP             Port#
--- ---------------- ---------------- -------------------------------- -----
<A>dd <D>elete <S>ave <Q>uit  -> Add

Enter node name    : frobozz
Enter shared secret: frotz
Enter host or IP   : frobozz.magick.org
Enter port number  :  [504]: 504

###    Node            Secret                   Host or IP             Port#
--- ---------------- ---------------- -------------------------------- -----
  1 frobozz          frotz            frobozz.magick.org               504
<A>dd <D>elete <S>ave <Q>uit  -> Save

Lobby>

+ +

As you can see in the above example, you have to enter the Citadel node +name, the DNS name or IP address of the server, and the port number the Citadel +service is running on. The "shared secret" is a password to allow the two +Citadel nodes to connect to each other to exchange network data. The password +must be identical on both ends of the connection -- when the operator +of the other Citadel node sets up the connection with your system, he/she +must use the same password.

+ +

Sharing rooms

+ +

Now you're ready to share rooms. You have to do this for each room you +want to share, and you have to do it from BOTH ENDS -- again, when you share +a room with another Citadel, they must share it with you as well. Let's +say you have a room called "Quiche Recipes>" and you want to share it +with the node you set up above. First, edit the room and flag it as a network +room:

+ +

Quiche Recipes> . Aide Edit this room
Room name [Quiche Recipes]:
Private room  [No]: No
Preferred users only  [No]: No
Read-only room  [No]: No
Directory room  [No]: No
Permanent room  [No]: No
Network shared room  [No]: Yes
Automatically make all messages anonymous  [No]: No
Ask users whether to make messages anonymous  [No]: No
Listing order [64]:
Room aide (or 'none') [none]:
Message expire policy (? for list) [0]:
Save changes (y/n)? Yes
Ok

Quiche Recipes)

+ +

Notice how the prompt changed? It was > before, but it's ) now. That +means it's a network room. Now you can tell Citadel that you want to share +the room with frobozz. Enter this command:

+ +

Quiche Recipes) . Aide Network room sharing

+ +

Your text editor will pop up (you did configure Citadel to use +your favorite text editor, right?) with a screen that looks like this:

+ +

# Configuration for room: Quiche Recipes
# Nodes with which we share this room
# Specify one per line.

+ +

All you have to do is enter the name of the other Citadel node (i.e. "frobozz" +in our example) on a line by itself. As usual, lines starting with a "#" +are comments. Just go to the end of the file, type "frobozz" (without the +quotes), save the file... and you're done!

+ +

At this point, you just sit back and enjoy. Your Citadel and the other +one will begin polling each other at regular intervals (once per hour by +default) and sharing messages.

+ +

Sending mail

+ +

You can send mail to any user on any node of your Citadel network. It +may take a little while for your system to learn the entire node list, though, +as this is done by watching incoming messages on the network and learning +which nodes are out there.

+ +

To send a private message, just enter user @ host as the recipient:

+ +

Mail> Enter message                                                            
Enter recipient: Some other user @ frobozz
 Feb 11 2003 11:36pm from I. M. Me to Some other user @ frobozz
type message here...

Entry command (? for options)  ->

+ +

Changing the polling interval

+ +

As previously mentioned, Citadel will poll other Citadel nodes for messages +once per hour. If this is not an acceptable interval, you can change it using +the .Aide System configuration General command. + Enter this command and look for the option:

+ +

How often to run network jobs (in seconds) [3600]:

+ +

Change it to whatever you like. For example, 15 minutes is 900 seconds. + So if you changed the default value to 900, network polling would occur +every 15 minutes.
