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 with the - Program.

You may charge a fee for the physical act of transferring - a copy, and you may at your option offer warranty protection in exchange - for a fee.

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:

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 +with the Program.

You may charge a fee for the physical act of transferring + a copy, and you may at your option offer warranty protection in exchange + for a fee.

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 +License.

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 +from distribution of the Program.

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 system - and a licensee cannot impose that choice.

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.

9. The Free Software Foundation may - publish revised and/or new versions of the General Public License from -time to time. Such new versions will be similar in spirit to the present -version, but may differ in detail to address new problems or concerns. -

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. If the Program does not specify a version - number of this License, you may choose any version ever published by the -Free Software Foundation.

10. If you wish to incorporate parts - of the Program into other free programs whose distribution conditions are - different, write to the author to ask for permission. For software which - is copyrighted by the Free Software Foundation, write to the Free Software - Foundation; we sometimes make exceptions for this. Our decision will -be guided by the two goals of preserving the free status of all derivatives - of our free software and of promoting the sharing and reuse of software generally. -

11. BECAUSE THE PROGRAM IS LICENSED - FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED - BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT - HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY - OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, - THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. - THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH - YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY - SERVICING, REPAIR OR CORRECTION.

12. IN NO EVENT UNLESS REQUIRED BY - APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY - OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED -ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL - OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM - (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE - OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM - TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY -HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

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. Here are -some configuration examples.

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.

Any existing Citadel installation which is at version 5.50 or newer may be upgraded in place without the need to discard your existing data files.

- -

Upgrading to a new version uses the same build procedure as compiling -the program for a fresh install, except that you want to do make install-exec - instead of make install. This will overwrite the programs but not -your data. Be sure to shut down citserver during this process! If -Citadel is running while you upgrade, you may face data corruption issues.

After doing make install-exec, you should run setup -again to bring your data files up to date. Please see the setup section -below for more information on this.

Using an external editor -for message composition

Citadel/UX has a built-in message editor. However, you can also use your + favorite text editor to write messages. To do this you simply put a line + in your citadel.rc file like this:

editor=/usr/bin/vi

The above example would make Citadel call the vi editor when using the -.Enter Editor command. You can also make it the default -editor for the Enter command by editing the citadel.rc - file. But be warned: external editors on public systems can be a -security hole, because they usually provide users with the ability to drop -into a shell on the host system, or save files using names other than the -name of the temporary file they are editing. If you intend to use an external -editor on a public BBS, make sure you use one that has been hardened for -such a purpose -- one which has had the 'shell' and 'save as' commands disabled, - as well as any other functions which a destructive user could use to gain - unauthorized access to your host system.

Printing messages

Citadel/UX can send messages to a printer, or just about anywhere else -in your system. The variable PRINTCMD in citadel.rc specifies -what command you use to print. Text is sent to the standard input (stdin) -of the print command.

So if you did this:

For example, -you could use a command like cat <<$HOME/archive to save copies -of important messages in a textfile. Again, this is probably something -you don't want to configure for a public BBS host -- most system administrators -don't want remote users sending arbitrary things to local printers.

The next step is to arrange for the server to start. The citserver + program is the main Citadel server. Before we cover the recommended method of starting the server, let's examine its usage options:

citserver [-hHomeDir] [-xDebugLevel] [-tTraceFile] [-d] [-f]

The options are as follows:

-hHomeDir - the directory your BBS data files live in. This should, -of course, be a directory that you've run the setup program against -to set up some data files. If a directory is not specified, the directory -name which was specified in the Makefile will be used.

-xDebugLevel - Set the verbosity of trace messages printed. The -available debugging levels are:

-xDebugLevel - Set the verbosity of trace messages printed. +The available debugging levels are:

1 - Internal errors (failed thread creation, malloc problems, etc.) -
2 - Network errors (broken sockets, failed socket creation) -
3 - Begin and end of sessions, startup/shutdown of server
5 - Server commands being sent from clients
7 - Entry and exit of various functions
8 - Entry and exit of critical sections
9 - Various debugging checkpoints (insanely verbose)

5 - Server commands being sent from clients
7 - Entry and exit of various functions
8 - Entry and exit of critical sections
9 - Various debugging checkpoints (insanely verbose)

-tTraceFile - Tell the server where to send its debug/trace output. - Normally it is sent to stdout.

-d - Run as a daemon; i.e. in the background. This switch would -be necessary if you were starting the Citadel server, for example, from an -rc.local script (which is not recommended, because this won't allow the server -to automatically restart when it is shut down).

-f - Defragment all the databases upon startup. This isn't normally -necessary due to the nature of the data stored in Citadel, but the option -is provided in case you need it. (Note that this only applies to GDBM installations; -if you are using Berkeley DB it has no effect.)

The preferred method of starting the Citadel server is to place an entry -in your /etc/inittab file. This will conveniently bring the server up when -your system is up, and terminate it gracefully when your system is shutting -down. The exact syntax for your system may vary, but here's an entry that -could be used on a Linux system:

Overview

- -

Citadel/UX, when installed properly, will do most of its maintenance by - itself. It is intended to be run unattended for extended periods of time, -and most installations do just that without any software failures.

- -

The system has seven access levels. Most users are at the bottom and have -no special privileges. Aides are selected people who have special access within -the Citadel program. Room Aides only have this access in a certain room. - Preferred users can be selected by Aides for access to preferred only rooms. - A sysop is anyone who has access to the various sysop utilities - these -are in their own executable files, which should have their permissions set -to allow only sysops to run them. You should either create a sysops group -in /etc/group, or use some other existing group for this purpose.

- -

Aides have access to EVERY room on the system, public and private (all - types). They also have access to commands starting with .Aide -in addition to being able to delete and move messages. The system room, -Aide>, is accessible only by those users designated as Aides.

A public access BBS or message board - since you do not know -who might want to log in, self-service account creation needs to stay enabled. - If you want to be strict about users identifying themselves, then you should - also require users to register (just remember to post a privacy policy if - you're going to collect personal information) -- then set the initial access -level to 1 (New User), so new users cannot post messages until after you've -validated them. For a more lax environment, you can remove the registration -requirement and grant new accounts level 4 (Normal User) access on the first -visit.
A private email/groupware system for your organization - in -this case, disable self-service account creation; you don't want strangers -welcoming themselves to your system. You'll probably also want to disable -registration, because you or some other site administrator will be entering -users' contact info when you create their accounts. Since this is also how -you assign their Internet e-mail addresses, it's probably a good idea to do -it yourself instead of expecting them to do it.

'Access level required to create rooms' is up to you. You might wish to -restrict the creation of new rooms only to Aides, or you might wish to allow -anyone to create a room. The latter is one of the Citadel culture's most -long-standing traditions; the former may be appropriate if users are abusing -this privilege.

- -

You have the ability to 'Automatically give room aide privs to a user who - creates a private room.' If you answer Yes, then any user who creates a -guess-name, passworded, or invitation-only room will automatically become - the room aide, and will have access to a subset of the .Aide - command set while in that room. If you would rather grant this permission - manually, answer No.

- -

Another tradition in the Citadel culture is to refrain from deleting -problem users, but instead to 'twit' them (reduce their access level to 2 -[Problem User]). You can then 'Automatically move problem user messages -to twit room' (answer Yes, then specify 'Name of twit room' and remember -to create that room). If you employ this logic, any user with level 2 (Problem -User) access will continue to have access to the same set of rooms, but all -messages posted will automatically be routed to the Trashcan (or whatever -you call your twit room).

- -

If you have Internet mail configured, you have the option of restricting -its use on a user-by-user basis. If you wish to do this, answer Yes to 'Restrict -Internet mail to only those with that privilege.' Obviously this makes no -sense for an internal e-mail system, but for a public BBS it might be appropriate.

- -

Normally, Aides have access to every room, public or private, except for -user mailboxes. They are also forbidden from Zapping rooms, -because the review of content is considered one of their roles. If you wish -to change these policies, the next two options allow you to. You may 'Allow -Aides to Zap (forget) rooms', in which case they may use the Zap -command just like any other user. Furthermore, if you 'Allow system Aides -access to user mailboxes', then they may .Goto any private -mailbox belonging to any user, using a special room name format.

- -

If your local security and/or privacy policy dictates that you keep a -log of all pages (instant messages) that go through the system, then answer -Yes to 'Log all pages'. If you answer Yes, you will be prompted for the -name of a room to which all pages will be logged. If you answer No, then -only the sender and recipient of each individual message will receive a copy.

- -

The next set of options deals with the tuning of your system. It is usually -safe to leave these untouched.

The 'Server connection idle timeout' is for the connection between client + and server software. It is not an idle timer for the user interface. 900 seconds (15 minutes) is the default and a sane setting.

- -

'Maximum concurrent sessions' is the highest number of user sessions you - wish to allow on your system at any given time. Citadel can scale to hundreds -of concurrent users, but if you have limited hardware or (more likely) limited -bandwidth, you might wish to set a maximum. You can also set it to zero for -no limit.

- -

'Maximum message length' is just that. This could be a good way to prevent -enormous multimedia files from finding their way into your message base. -This maximum is enforced in all protocols and is also advertised by the ESMTP -service.

- -

The minimum and maximum number of worker threads can be tuned to your -liking. Citadel will attempt to keep one worker thread running per session, -within these constraints. You should be aware that due to the use of the -worker thread model, Citadel can handle a large number of concurrent sessions -with a much smaller thread pool. If you don't know the programming theory -behind multithreaded servers, you should leave these parameters alone.

The next set of options affect how Citadel behaves on a network.

- +

How often to run network jobs (in seconds) [3600]: 
SMTP server port (-1 to disable) [25]: 
POP3 server port (-1 to disable) [110]:
IMAP server port (-1 to disable) [143]:

- -

'How often to run network jobs' refers to the sharing of content on a -Citadel network. If your system is on a Citadel network, this configuration -item dictates how often the Citadel server will contact other Citadel servers -to send and receive messages. In reality, this will happen more frequently -than you specify, because other Citadel servers will be contacting yours at -regular intervals as well.

- -

Then you can specify TCP port numbers for the SMTP, POP3, and IMAP services. - For a system being used primarily for Internet e-mail, these are essential, -so you'll want to specify the standard port numbers: 25, 110, and 143. If -Citadel is running alongside some other mail system, though, then you might -want to choose other, unused port numbers, or enter -1 for any protocol to -disable it entirely.

Default user purge time (days) [120]:
