.The first field is the name of the site as specified in the newsfeeds(5) file.The second field should be the hostname or IP address of the remote site.The third field, if non-empty, specifies the default tail truncation size of site s batchfile.This is passed to shrinkfile as the sflag.If this field is empty, no truncation is performed.The fourth field specifies some default flags passed to innxmit(8).The flag a is always given to innxmit and need not appearhere.If no t timeout flag is given in this field and on the nntpsend command line, t 180 will be given to innxmit.HISTORYWritten by Landon Curt Noll (chongo@toad.com) for InterNetNews.SEE ALSOinnxmit(8), newsfeeds(5), nntpsend(8), trunc(1)nologinnologin Prevent usual users from logging into the system.DESCRIPTIONIf the file /etc/nologin exists, login(1) will allow access only to root.Other users will be shown the contents of this file andtheir logins refused.FILES/etc/nologinSEE ALSOlogin(1), shutdown(8)Linux, 29 December 1992overview.fmtoverview.fmt Format of news overview database. passwd1169DESCRIPTIONThe file /news/lib/overview.fmt specifies the organization of the news overview database.Blank lines and lines beginningwith a number sign (#) are ignored.The order of lines in this file is important; it determines the order in which the fields willappear in the database.Most lines will consist of an article header name, optionally followed by a colon.A trailing set of lines can have the word fullappear after the colon; this indicates that the header should appear as well as its value.If this file is changed, it is usually necessary to rebuild the existing overview database using expireover(8) after removing allexisting overview files.The default file, show here, is compatible with Geoff Collyer s nov package:Subject:From:Date:Message-ID:References:Bytes:Lines:## Some newsreaders get better performance if Xref is present#Xref:fullHISTORYWritten by Rich $alz (rsalz@uunet.uu.net) for InterNetNews.Intended to be compatible with the nov package written byGeoff Collyer (geoff@world.std.com).passwdpasswd Password file.DESCRIPTIONpasswd is an ASCII file that contains a list of the system s users and the passwords they must use for access.The password fileshould have general read permission (many utilities, such as ls(1), use it to map user IDs to usernames) but write access onlyfor the superuser.In the good old days, there was no great problem with this general read permission.Everybody could read the encryptedpasswords, but the hardware was too slow to crack a well-chosen password, and moreover, the basic assumption used to bethat of a friendly user community.These days, many people run some version of the shadow password suite, where /etc/passwd has *s instead of passwords, and the encrypted passwords are in /etc/shadow, which is readable by root only.When you create a new login, leave the password field empty and use passwd(1) to fill it.A star (*) in the password fieldmeans that this user cannot log in via login(1).There is one entry per line, and each line has the format:login_name:passwd:UID:GID:user_name:directory:shellThe field descriptions arelogin_name The name of the user on the system.password The encrypted optional user password.UID The numerical user ID.GID The numerical group ID for this user.user_name The (optional) comment field (often a full username).directory The user s $HOME directory.shell The program to run at login (if empty, use /bin/sh). Part V: File Formats1170NOTEIf your root file system is on /dev/ram, you must save a changed password file to your root filesystem floppy before you shutdown the system and check the access rights.If you want to create user groups, their GIDs must be equal and there must bean entry in /etc/group, or no group will exist.FILES/etc/passwdSEE ALSOpasswd(1), login(1), group(5), shadow(5)Linux, 24 July 1993passwd.nntppasswd.nntp Passwords for connecting to remote NNTP servers.DESCRIPTIONThe file /news/lib/passwd.nntp contains host-name-password triplets for use when authenticating client programs to NNTPservers.This file is normally interpreted by the NNTPsend-password routine in libinn(3).Blank lines and lines beginning witha number sign (#) are ignored.All other lines should consist of three or fields separated by colons:host:name:passwordhost:name:password:styleThe first field is the name of a host and is matched in a case-insensitive manner.The second field is a username, and thethird is a password.The optional fourth field specifies the type of authentication to use.The default is authinfo, whichmeans that NNTP authinfo commands are used to authenticate to the remote host.If either the username or password areempty, then the related command will not be sent.(The authinfo command is a common extension to RFC 977.)
