I'm averaging a couple new entries I'd like to see an entry like "Why are usernames restricted to 8 characters in length?" Proposed answer (frmo what I've read in the archives): Just changing UT_NAMESIZE and "make world" won't work, and besides it's not considered a Good Idea. Two main reasons for that: 1- the value for the user name length is hardcoded all over the place, AND in different ports. You need to edit a whole lot of source code. Among others: (this list from jc@irbs.com (John Capo)) /usr/src/include/protocols/rwhod.h: char out_name[8]; /* user id */ /usr/src/usr.sbin/lpr/lprm/lprm.c:static char luser[16]; /* buffer for person */ /usr/src/usr.bin/rdist/main.c:char user[10]; /* user's name */ /usr/src/usr.bin/rdist/server.c: static char user[15], group[15]; /usr/src/games/battlestar/externs.h:char uname[9]; /usr/src/release/sysinstall/anonFTP.c: char uid[8]; /* UID */ /usr/src/libexec/rexecd/rexecd.c: char user[16], pass[16]; /usr/src/libexec/rshd/rshd.c:char username[20] = "USER="; /usr/include/stdio.h:#define L_cuserid 9 /* size for cuserid(); UT_NAMESIZE + 1 */ 2- Sun's (most?) NIS clients don't support long usernames It has been said that this feature won't appear in 2.1. -- -- Renaud Waldura -- -- Softway International, Inc -- -- rw@softway.com -- -- 185 Berry Street, Suite 5514 -- -- San Francisco, CA 94107 -- -- USA -- -- Tel (415) 896-0708 -- Fax (415) 896-0709 -- http://www.softway.com/ -- --
