Fix conf.h up, and then come back here. X X Back already? Ok. Now following the bouncing numbers: X X 1. Create the access file with the proper entries. X This file goes wherever you said ACCESS_FILE X was supposed to be in common/conf.h. It's format is X explained in the manual entry for nntpd.8c. X A sample access file is in ../support/access_file. X If you don't care who (ab)uses your news server, X you can have the line "default read post" in your access X file, which will allow anyone on the network to X read and post news via your server. See the manual X page for a better explanation. X Parts two and three are necessary if you're running with TCP: X X 2. Make an entry for "nntp" in /etc/services. Should X be port number 119, tcp. I.e., should look something like: X nntp 119/tcp readnews # Network News Transfer Protocol X X Sun users running yp should yppush this file to make sure all X the clients get it. X X 3. Check ../common/conf.h to make sure you're set to do what X you want to do with inetd (i.e., #define ALONE or #undef ALONE). X If you are using inetd, X X a. Add a line to /etc/inetd.conf, or whatever your X configuration file is, to reflect the presence X of the news server. On 4.3 BSD machines this should X look like: X nntp stream tcp nowait root /etc/nntpd nntpd X X while under Ultrix or 4.2 BSD machines: X nntp stream tcp nowait /etc/nntpd nntpd X X On a Sun, the file is /etc/servers; the line looks like: X nntp tcp /usr/etc/in.nntpd X X Be sure to yppush your /etc/servers file if you run X yellow pages. X X Don't forget to kill -HUP your inetd. X X If you're NOT using inetd, X X a. Edit ../common/conf.h to have the line X X #define ALONE X X to compile in code for the stand alone server. X X b. You may as well also define "FASTFORK" in X ../common/conf.h. This causes the server not to X read in the active file every time it forks, but X rather to stat it every READINTVL seconds, and if X the file has changed since the last read, to X read it in again. This makes the children run X faster, since they don't have to read the active X file every time the parent forks off a child, but X the parent server will eat more cpu, doing X stat()s every 10 minutes or so. If your server machine X is heavily loaded, you might leave this out. X X c. Change /etc/rc.local to start the server at X boot time. X Else, if you're using decnet: X X 2. && 3. Define the NNTP object with ncp: X ncp define object NNTP number 0 file /etc/nntpd ncp define object NNTP default user guest type stream X ncp set object NNTP all # just once for the running system X X 4. Compile the server by doing "make". X X 5. Cd .. and continue with the rest of the stuff; you'll X wind up doing a make install later.

X** X** This include file attempts to categorize possible error X** exit statuses for system programs, notably delivermail X** and the Berkeley network. X** X** Error numbers begin at EX__BASE to reduce the possibility of X** clashing with other exit statuses that random programs may X** already return. The meaning of the codes is approximately X** as follows: X** X** EX_USAGE -- The command was used incorrectly, e.g., with X** the wrong number of arguments, a bad flag, a bad X** syntax in a parameter, or whatever. X** EX_DATAERR -- The input data was incorrect in some way. X** This should only be used for user's data & not X** system files. X** EX_NOINPUT -- An input file (not a system file) did not X** exist or was not readable. This could also include X** errors like "No message" to a mailer (if it cared X** to catch it). X** EX_NOUSER -- The user specified did not exist. This might X** be used for mail addresses or remote logins. X** EX_NOHOST -- The host specified did not exist. This is used X** in mail addresses or network requests. X** EX_UNAVAILABLE -- A service is unavailable. This can occur X** if a support program or file does not exist. This X** can also be used as a catchall message when something X** you wanted to do doesn't work, but you don't know X** why. X** EX_SOFTWARE -- An internal software error has been detected. X** This should be limited to non-operating system related X** errors as possible. X** EX_OSERR -- An operating system error has been detected. X** This is intended to be used for such things as "cannot X** fork", "cannot create pipe", or the like. It includes X** things like getuid returning a user that does not X** exist in the passwd file. X** EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp, X** etc.) does not exist, cannot be opened, or has some X** sort of error (e.g., syntax error). X** EX_CANTCREAT -- A (user specified) output file cannot be X** created. X** EX_IOERR -- An error occurred while doing I/O on some file. X** EX_TEMPFAIL -- temporary failure, indicating something that X** is not really an error. In sendmail, this means X** that a mailer (e.g.) could not create a connection, X** and the request should be reattempted later. X** EX_PROTOCOL -- the remote system returned something that X** was "not possible" during a protocol exchange. X** EX_NOPERM -- You did not have sufficient permission to X** perform the operation. This is not intended for X** file system problems, which should use NOINPUT or X** CANTCREAT, but rather for higher level permissions. X** For example, kre uses this to restrict who students X** can send mail to. X** X** Maintained by Eric Allman (eric@berkeley, ucbvax!eric) -- X** please mail changes to me.
