Subject: v13i071: A BBS written in /bin/sh, Part01/02 Newsgroups: comp.sources.unix Sender: sources Approved: rsalz@uunet.UU.NET Submitted-by: Rob DeMarco <ncoast!robertd> Posting-number: Volume 13, Issue 71 Archive-name: sbbs/part01 This is SBBS - For Sigma Bulletin Board System. This is a 90% shell script BBS with only two files writen in C. You may have to modify these programs for your system. The shell scripts should work on ANY UNIX system that suports standard /bin and /usr/bin directories, redirection, the four quoting mechanisms, variable substitution with '{}'s. In short, it should work on any semi-modern Bourne Shell. Contact me if you have any trouble. [> Rd PS: It does NOT require a Makefile, so don't worry. #!/bin/sh # shar: Shell Archiver # Run the following text with /bin/sh to create: # README # admin.doc # config.tbl # setup.doc sed 's/^X//' << 'SHAR_EOF' > README X XSBBS Copyright(C) 1987 Rob DeMarco XAll rights reserved. X XSBBS may be modified only at your site. XIt may be redistributed but NOT Xmodified in any way and all files must Xstay intact. XIt may not be sold. X X The following files are programs that SBBS use or documentations. Move Xall the programs to a specific place and move the documentations were best Xput. Read setup.doc before installing SBBS. X X This archive(s) contain four documentations (including this one), X two C programs - initial.c and lock.c(*). X ~28 shell script files writen in Bourne Shell. X X---- X* initial.c is a fake "shell" that is called up when a person logs in as a XSBBS user or su's to it. It contains a simple function; execl(). This runs Xa shell script login-sig as the LOWEST level shell. If your system doesn't Xsuport execl(), look for a simular function. X Xlock.c shouldn't give you much trouble. It works on a system III and can Xbe easily modified to work on any system. X XDo neccessary changes to these files BEFORE you run "install". X X SHAR_EOF sed 's/^X//' << 'SHAR_EOF' > admin.doc X XSBBS ADMINISTRATION HELP X---- -------------- ---- X XAfter you have read the instructions on how to set up SBBS, you must get Xyour self familiarized with all the SBBS files. X XI have assumed that you ran 'install' and your SYSOP account was set up. XA 'SYSOP' account is a special user that has many privileges. Among them are Xuser-management systems, Message Bases, and U/DL bases. There are more; these Xwill be explained. X X XI. Familiarization of SBBS X X Your account was created when you ran the program install. Install makes Xthe necessary preparations to allow SBBS to run. If you are not the head XSYSOP and didn't run install you may skip this whole section on SBBS Xfamiliarization as it does not concern you. X X Your ID and password was stored in a file called ~/admin/profile/logins. XOther information on you is stored in ~/admin/profiles/members. Check these Xfiles out and see how they are stored. (In the examples, we will assumed you Xcalled ONCE before.) X X $ cd $home/admin/profile < $home equals SBBSs home directory. X $ ls X cmdlog < User command log X lastcaller < The last caller X log < Log of users and their times of login and logout X logins < User IDs and passwords X members < More information on users X newusers < New Users who have called.

X X $ cd $home/mail X $ ls X 1 X $ cd 1 X $ ls X 1 X 2 X X The directory "1" in the "mail" directory is where all of user 1's Xmail is. Since it is private, we woun't look at the mail. (Files "1" and "2") X X $ cd $home/new X $ ls X 1 X $ cat 1 X 1:4 X X This is a file that contains information on the last message he Xread from the Message Bases (More on this later). In Message Base "1", he Xread all the way up to message #4. This, for your information, is the "General" XMessage Base. X X Now let's look at the "bulletins" and "udl" directories. X X $ cd $home/bulletins X $ ls X 1 < This is a bulletin from the sysop (User #1) welcoming everyone to X his new system. X $ cat 1 X < Bulletin > X $ X X The bulletin will be displayed to any one logging in to his system one Xtime only. They may reread the bulletins by a special command. X X $ cd $home/udl X $ ls X new X $ X X This directory stores all the files the users upload. He has created no X"Topics". Topics are specific areas where users store files. These files Xpertain to the "Topic". The directories are stored as numbers. The actual Xtopic-names are stored in files. The "new" directory is automatically Xcreated when the SysOp ran "install". It stores "new" uploads that are awaiting Xapproval be the SysOp or CoSysOps. X X Now we explore the final directory.

X X $ cat newnews X 1:1 X X This file containes information on what the last bulletin read was. X Remember the "bulletins" directory? X X $ cat prlib X 1: Access DataBase XI:/u/local/dbxi X 2: List or add city services:/u/local/cleserv X 3: List or add 216 numbers.:/u/local/216list X X This is the program library. This is available online to SBBS users. The Xfirst field (Of 3 seperated by colons) is the option number that the user Xtypes to access it. Field 2 is the formal name the user sees. Field three Xis the actual program to run. This may contain variables , quotes and ';' Xseperaters if you wish. But a special "variable" must be set to do this; Xotherwise it will take the whole third field as the program to run -- without Xevaluating the metacharacters. X X $ cat com ecom main_menu <menus X <com menu (bbs)> X <ecom menu (editor)> X <main_menu menu. (main menu)> X $ cat protocols.up X 1:Ascii:echo Start Transmitting. Send a CTRL-D when finished. ; cat >> X The first field is the udl protocol option. It is one of the options listed Xwhen someone uploads a file. It was automatically set up when "install" Xwas run. The second field is the formal name the protocol. The third is the Xactual program to run. That special variable isn't needed here because all Xmetacharacters will automatically be evaluated. So be careful to quote Xany metacharacter that is to be taken literally like *,",;,etc. X X Please understand it. You must enter the protocols yourself. (except Ascii) X X Examples: X X 2:Xmodem:/u/local/umodem -rt X 3:Kermit:/u/local/kermie -rb X X Don't worry about file names. This is done for you because the file Xnames will differ as people upload more and more of them. X X $ cat protocols.down X 1:Ascii:Prepare for transmission in 10 seconds. ; cat X The same applies for this file except its used when downloading. X X Examples: X X 2:Xmodem:/u/local/umodem -st X 3:Kermit:/u/local/kermie -sb X X $ cat config X $ X X Where all system variables (including the one to evaluate the Xthird field or "prlib") are stored. X X The format is "variable=value" or simply "variable=" for some of them. X X Consult config.tbl in your documentation package for more details. X X Now it's time to learn how to use SBBS it self. X XII. SBBS - THE BBS X X There are two ways to tackle this difficult task of explaining SBBS. XI could explain the whole SBBS system , including the general commands that Xare available to all the users OR I could explain only the commands Xavailable to high-level users. X X But do to the accident that caused my administration documentation to be Xcompletely erased, I have no time to be complete. I will try my best to be able Xto explain how to run SBBS. But you will have to wait until SBBS is released Xto the public before a better documentation is written up. X X Log on to SBBS X X It will display the copyright message and prompt you for your ID. XYou may exit here by typing OFF. If you are new to SBBS you would type NEW. It Xwill ask you questions and create an account for you. An account is your own XID which makes you a member of SBBS. After your ID is created, you may then Xlog in SBBS with your newly created ID. If you enter your ID, it will ask for Xa password. You told SBBS this when you requested to be a new user or when (if Xyou are the SBBS administrator) you ran install. Type the password. It will not Xbe echoed back to you. This is to protect your password. If your password Xattempt fails then it will reject you. If you enter incorrect information Xthree times in a row you will be knocked off. If you are accepted, you will be Xput in SBBS. You will be told the last caller if there is one. You are then Xput in the "SBBS main" prompt. The two important commands to remember are X'A' and '?'. A command is a letter you type from SBBS main to do something. XA '?' will tell SBBS to display a summary of commands. 'A' is a special Xcommand and can ONLY be used by level-3 users. It's the Administrative Shell. X X Levels of users X X There are four "levels". These levels tell what privileges a user may Xhave. The user who ran install automaticly has a level of 3. Anyone Xwho used NEW from the SBBS login automaticly has an access of 0. Here is Xa list of the four levels and what they can do. X X Level-3: These users (usually only 1) may access EVERYTHING on SBBS. X Level-2: These users may access everything including the Administration X commands except 'A'. This is the shell. X Level-1: "Normal" access. This access level has access to all the X commands save the Administration commands. X Level-0: Limited access. Usually new users. X X More on the login routine X X If you are a Level-3 user, please read this section. Otherwise you may Xskip it or read it for background. But only Level-3 users may perform the Xfollowing things. X X From SBBS main, type A. You will get a shell. I assume that you are in the XSBBS home directory. If not, change to it. X X $ cd misc X X There are a few things we will deal with "config". The file called config Xwill allow you to configure your SBBS system to your specifications. These Xconfiguration commands are called C variables. (No relation to that hidious Xprogramming language called "C" :-[ ) These C variables are stored in the Xconfig file; in this format: X variable=value X or simply X variable= X To learn what all the C variables are and what they do, consult the Xdocumentation config.tbl. This is a full explanation of all the variables and Xwhat they do. We will explain a few of them now. X X First there are two C variables we will learn. Cycle and newuser. As you Xrecall, if your login attempt fails a certain amount of times, you will be Xkicked off. You can control the amount of times it takes by the cycle C Xvariable. The format is cycle=times. X X Example: X X cycle=5 - This allows five mess-ups before it disconnects a user. X X The next C variable is newuser. The purpose of this one is to print a file Xwhen a person requests to be a new user. This is usually used to print the Xrules or instructions on how to use the system. The form is newuser=file. The Xfile should be an absolute path to avoid errors. Never fully assume a certain Xsituation is true. Always think of all possibilities. X X There is also another C variable. Form is "elite=". No value is Xnecessary. This instructs SBBS not to accept new users. It will also fail to Xnotify users that there is such an option as NEW. X X A few more C variables. X X name=Erie Coast Boating and Sailing Club X version=1.0.0 X shell=/bin/csh X X These are almost self explanitory. Name and version will print there Xrespected values from time to time. Including the Login routine. The shell XC variable is the shell to run when the 'A' command is used. Otherwise, as you Xknow, the default shell is /bin/sh. X X Becoming new to helping the new X X Since you are a level-2 or a level-3 user, you may validate other new Xusers. This is done be raising them from level-0 to level-1. There are special Xcommands to work with new users and existing users. X X Getting a User Log X X A User Log is a list of who called and when. It also tells when they left. XAs you have recalled if you read the section on files, this is the file X~/admin/profile/log. SBBS will keep track up to 20 log entries before it Xonly prints the last 20 callers only. You may change this number by the use Xof the C variable "log". Just suply how many entries to keep after the equal Xsign and SBBS will do it. The command is 'U'.It may be used by all level users. X X Listing users X X From time to time you may wish to list certain users. Type 'L' and you Xare now in the list mode. Again, this option may be used by all, but only Xlevel-2 or level-3 users may see the information such as the street address. XThe other Level-0 and level-1 users only see limited information such as ID, Xname, and access. Just type the ID of the user to view and his information Xis shown. Type -1 as an ID to escape to the main menu. X X The neucleous of user management X X This is the 'V' command; available only to level-2 and level-3 users. In Xhere you have six commands. Since you are at a command prompt, you may type X'?' if you need help. X X The first is 'L'. This command lists all the new users. This so you know Xwho is new and you may do something to them. (Usually raise their access to 1) X X The next is 'A'. This command allows you to change the access level of any Xuser -- not just new ones. Simply type the ID of the user and his new access. X X Another is 'C'. This one will clear new users from the new user file in Xorder to avoid confusion. This will only clear people on the new user file. XJust type the ID to clear. Note that this is different from 'R', which Xdeletes a user from the SBBS logins and members files and thus deletes or XRemoves a user from SBBS. 'C' merely deletes the line from the new user file. X X The final user management command, 'R', removes a user completely from XSBBS. Type the ID of the user and it will display there name and ask for Xconfirmation. Be careful with this command. X X One of two other commands in the 'V' command/function is 'V'. (Coincidental X, nothing more) It allows you to "view" the command log. The log that tells Xwhat each user did. It shows the ID, colon, the-next-commands-seperated by Xcolons. X X Example: X 1:M:L:U:I:E X X NOTE: This only keeps track of commands entered in SBBS main. Not the Xcommands entered in Validation Mode or any other mode or sub-menu. X X 'D' for delete/refresh will clear the command log because SBBS does not Xdo this for you. Therefor, you don't need a C variable. X X Some other miscellaneous things X X The following is a discussion on some other miscellaneous things. X X Many times when a person logs on a BBS, they get a welcome message. SBBS Xdoes the same thing. It shows a file that is shown every time a person logs Xin. You may not see it but that's because the file is blank. To show the Xfile and add your message, edit ~/misc/openmes. This file is sort of like XUNIX's motd file. Once you're finished, any people that logs in will see this Xmessage. X X On the other side of the scale, many times you want "Good bye" message. This Xis easy to accomplish too. Just edit ~/misc/closing. Add what you want and Xthat will be shown next time you log off. X X Sometimes you want to show information on your BBS to other users. XThis can be done by the 'I' command. It will display information if there is Xany. If there is not and you would like to add it. Edit ~/misc/info. Add the Xinformation. Of course you must have level-3 access to do this as editing Xany file requires the 'A' command. The same applies for the former two files. X X As was discussed before, there may be times you wish to post "updates" Xabout events surrounding your BBS system or services. As I told you, the Xbulletins are only displayed once. But they can be reread by another command. XType 'B' from SBBS main and enter the subject of the update. There is a Xdefault provided for you. You don't have to use this default. Then you compose Xthe message using the SBBS editor. And you're done. X X You may reshow any bulletins by the 'O' command from SBBS main. In fact, Xany user can. Just answer Y or N when it asks you if you wish to read a certain Xbulletin. When it scans through all of them, it will exit. X X Message Bases--a way to communicate X X There is a way to have all users talk to each other through one common Xarea; called the Message Bases. It's the 'M' command from SBBS main. The XMessage Bases are divided into specific topics - called (strangely enough) Xa "message base". Each message base has a name and a number associated with it. XThe name is what the messages posted in this area concern. The number is how Xyou identify the base. You would not be required to enter the whole topic Xwhich may be more then one word. X X Posting, Killing, and Editing. X X After entering the message base, you will be put in the "General" base. X(#1) You can post or read messages in this area. To post a message, type 'P' Xfrom Message Main (The "General)" prompt.) prompt. Enter the subject of Xyour message. The subject is more specific about what your message is Xabout. It should pertain to the topic. Which is General. So it could be any- Xthing. For someone to read it (including you) you type either 'I', 'F', 'R', or X'N'. 'G' reads messages from all message bases. If you don't know what these Xcommands stand for, type '?' at Message Main. X X You may wish to kill a message you made. Any user may do this. Simply Xtype 'K' and enter the message number. (not the subject. The number can be Xseen when reading your message.) Unless you are a level-2 or level-3 user, Xyou may not kill messages you did not post. Level-2 and level-3 may delete Xany message. X X Editing a message X X You may have made a mistake you will regret. Don't fret. Just use option X'O' (For "open message to edit." Not 'E'. don't get thrown off.) and type Xthe message you were going to edit. If you are not a level-2 or level-3 user, Xyou may only edit YOUR message. Level-2 and level-3 users may edit any message. X X Creating a message base X X If you just installed SBBS, chances are that there is only the General Xmessage base. To list all of the message bases, type 'L' from Message Main. XIf you wish to create more, type 'C'. Then enter the topic for the message Xbase. It then asks for you to confirm your topic and creates it. This is ONLY Xavailable to the level-2 and level-3 users. X X The MBM X X MBM stands for Message Base Manager. An MBM assumes privileges for level X2-3 users. But his power is limited to a particular message base only. And he Xstill may not use the 'C' option. Further more, an MBM only exists in Xmessage bases. Not any other place. He may be an MBM of more then one message Xbase but these must be specificly told to SBBS. There may be only one MBM. The Xfollowing are available to level-2/3 users and the MBM. This controls what Xrestrictions on a message base may be imposed and what the MBM is. This Xoption is 'Z'. It's a sub-menu with the options inside. Only level-2 , level-3, Xand MBMs may use it. And they can use ALL of the features COMPLETELY. (NOTE: XMBMs can use the E and K commands from Message Main just like a level-2 or Xlevel-3 user.) X X The 'Z' command in Message Main X X When you type this command, some information about the current message Xbase is displayed. You may get this information back by the 'I' command. If Xyou need help type '?' , as always. To exit type 'E'. X X Changing or assigning the MBM X X The 'B' command from this sub-menu allows it. Even an MBM may use this to Xswitch over control to another user. Type the ID of the user who you want to Xbe MBM. X X Restrictions X X The 'C' command allows you to change restrictions. It shows three different Xrestrictions: access, restricted list, none. To lift any restrictions, type X'N'. To restrict users by access, type 'A'. Then type a list of accesses that XMAY use that message base. INCLUDE YOURS OR YOU WILL NEVER GET BACK IN! You Xmay also make a restricted list--the 'R' option. Type the users ALLOWED in. XAgain, INCLUDE YOUR ID NUMBER! OR YOU WILL NEVER GET BACK IN! If you make a Xmistake, don't worry. As long as you don't exit the message base, you can Xcorrect it. If you wish to add or delete restrictions, you have to retype them. XFor accesses this isn't to bad. But for a restricted list it may be tedious. XYou must type ALL IDs of the users to let in. X The Program Library and UDL X X Choose option 'P' from SBBS main. What you get is list of programs Xavailable. Type the number of the program and it will run it for you. Two Xspecial "commands" are also available: '$', and '#'. '$' will exit to the Xmain menu. '#' will relist the programs. X X Of course, you will want to add your special programs. You may do this Xonly if you are a level-3 user. Go get the Administrative shell. Then go to Xthe misc directory and edit prlib. Each line should be three fields seperated Xby colons. The first field is a unique number that identifies that program. It Xmust be a number and it is a good idea for them to be in order! :-) The second Xfield is the formal name. This is the name the user sees when he lists the Xprograms available. The third field is the actual program to run. X X If you wish to use arguments, environment variables , quotes, Xredirection characters or ';'s then you must set up a C variable called "eval" Xso that it may EVALuate the line. Using all of the things including file Xsubstitution. It doesn't require a value but be sure to have the equal sign. X X Examples: X X 1:DCoM II:/u/local/decom X 2:Extrox Editor:/u/local/extrox X X (allowed with C variable eval set) X X 1:Telex System:/u/local/telex -r X 2:Rod Trox:/u/local/dep -r ; ls|wc X X X The File Facilities X X There is a feature that allows people to store and retrieve text and/or Xprogram files. This is done by the DataBases. It's the 'D' command. X X From the UDL main prompt you can enter a DataBase, exit(E), list(L) the XDataBases again, (It lists automaticly the DataBases available. When you Xfirst install SBBS, there will be none.) create a DataBase,(Only with if you're Xlevel-2 or level-3.) or approve new uploads. (Level-2/level-3 only. XExplained later.) X X To enter a DataBase, enter its number. You will be put in that DataBase Xand be at the new FILE prompt. X X Chances are that if you just installed SBBS you woun't have any Data- XBases. You may create them. A DataBase is an area with a specific topic that Xdescribes files in that area. To create a DataBase, type 'C'. Then describe Xwhat that DataBase is intended for. It will be stored and given a number. You Xmay now enter the DataBase. X X At the FILE mode, you can do things like upload, download and list files. XAgain, if you need help, type '?'. X X Uploading files X X If you upload a file, it must be approved by a level-2 or level-3 user. XIf you are one, you must approve it your self. To upload, answer all questions Xand choose a protocol. A protocol tells how both of your computers communicate. XThere is already one -- ascii. This simply shows the file and your computer Xis responsible for "capturing" it. You may add more protocols if you are a Xlevel-3 user. Choose 'A' from SBBS main and go to the misc directory. Edit Xprotocols.up. (Note: Download protocols take there own seperate file. Every Xthing you learned about setting upload protocols may be applied to download Xprotocols. Remember that download protocols are used when downloading a Xfile. It takes its protocol from protocols.down) XAgain, it has three fields seperated by a comma. And again the first field is Xthe number the user chooses to use that protocol. Again the second field is Xthe name the user sees. The third field is the program that runs the protocol. XOne is there already. Its the ascii one. Please note that C variable eval need Xnot be set to evaluate metacharacters as it will automaticly evaluate the line. X X Examples: X X 1:Ascii:echo Transmit. Enter A CTRL-D when finished. ; cat >> X (That line already in file) X 2:Xmodem:/u/local/umodem -rt X 3:Kermit:/u/local/kermie -rt X X Remember to also edit protocols.down for adding the simmular protocols. X X 1:Ascii:echo Prepare to receive. ; cat X (already in there) X 2:Xmodem:/u/local/umodem -st X 3:Kermit:/u/local/kermie -st X X See the little but important differences between the two files? X X Approving files X X Finally, a file uploaded must be approved. Choose 'N' from UDL main. If Xthey're no uploads it will send you back with a "No uploads." message. Other- Xwise it will cycle through all the uploaded files. Remember where they're Xstored? The udl/new directory. It will print information on the file (like Xwho uploaded it and what DataBase) and ask you what to do with it. Make a Xdecision and go on. Once you're through, it will do what you told it to and Xexit. The commands are: X X a - Abort. Go back to UDL main and leave all files in tact.. X v - View first and last ten lines of a file. X d - Delete that file and don't move it to a DataBase. X m - Move the file to that DataBase -- approve it. X X X This concludes are administration documentation. Direct questions to Xrobertd@ncoast.UUCP X...uunet!amdahl!sun!mandrill!ncoast!robertd SHAR_EOF sed 's/^X//' << 'SHAR_EOF' > config.tbl X The following is a list of valid Xvariables for config. NOTE: All Xvariables are in the form "variable=v". XThere are NO spaces between the "=" Xsign. Even if there is no value needed Xto suply to the variable, there must Xbe an "=" sign after the variable. X X Example: X X cycle=4 X elite= X X Not: X X cycle = 4 X elite X X Default numeric values will appear Xin parentheses. Anything in {}'s should Xbe substituted with its real value and Xbe a PART of the variable name on the Xleft side of the "=". X X[ Variable ] [ Meaning ] X------------ / ------------------------ Xname=name The name of your BBS is X "name".Example:name=UNIX Xversion=vs The version of your SBBS X BBS is "vs". Xcycle=cycle(3) Number of times SBBS X will prompt a user to X re-enter illegal ID or X password before exiting. Xcls=cls_cmd This tells SBBS what X program to run when it X needs to clear the X screen. DEFAULT: echo ^L Xeval= Set eval flag. This X evaluates commands found X in ~/misc/prlib, X ~/misc/protocols.up, and X ~/misc/protocols.down. X This allows commands to X be called up with X arguments, environment X variables, etc. Xelite= Set elite flag. This X will disallow new users X from registering. Xnewuser=file What file to show when X a new user registers. Xshell=shl_prg Shell to run when the X administrator runs the X "A" option. Default: X /bin/sh. Xlog=lognoms(10)How many log names to X keep in the userlog X before clearing it and X starting again. Xmbm{b}=mbm The user with the ID of X "mbm" will have control X of message base "b". X This can be set by the X administrator or MBM of X the base WITH IN SBBS by X the "Z" option in the X Message Base. Xb{b}=r:d Message Base "b" is to X have a restriction type X of "r". ("restrict" or X "access") And allow only X people with IDs or X access levels (Depending X on value of "r") to X access that Message Base.

As SBBS maintains its own list of BBS users (and their Xpasswords), this allows users to simply type "su sbbs" to enter the program. XAlternately, if your version of UNIX ignores the default login shell when a X"su" command is executed, users can use "exec login sbbs". With a bit of Ximagination and a knowledge of shell programming techniques, any number of Xalternate methods can be devised. X XAll SBBS programs and files reside in one directory. The software is normally Xconfigured to be based in the directory /u/sbbs, although this can be changed Xto suit your particular needs. If you wish to place SBBS elsewhere, edit the Xfile login-sig and change the line X X.in +5 Xdir=/u/sbbs X.in -5 X Xreflect the desired location. X XAfter you have decided on SBBS's home, make sure that directory is created and Xthen create a subdirectory called programs. All files from the shell Xarchives should be kept in this directory, usually called /u/sbbs/programs. X XFrom this point on, the directory you have chosen for SBBS to reside in will Xbe referred to as ~sbbs. X XAfter insuring that a copy of every file from the shell archives exists in X~sbbs/programs, run the "install" program. This will automatically create the Xnecessary SBBS data files. X XFinally, add an appropriate line to your /etc/passwd file to allow users to Xaccess SBBS. A typical example follows. X X.in +5 Xsbbs::1000:1000:SBBS user:/u/sbbs:/u/sbbs/programs/initial X.in -5 X X X.ce 1 XSupport X XIf you wish to become a registered owner of SBBS, contact robertd@ncoast.UUCP. XSupport will include periodic updates and possibly an SBBS newsletter.
