When allowing rsh/rlogin access, you have to modify /etc/login.access. >How-To-Repeat: Setup a freebsd box that allows root access over the net, then try to login from another non freebsd box. >Fix: This patch disables the use of the rootterm() function in login.c This then defaults to using the /etc/login.access file for the telnetd sessions. *** ./usr.bin/login/login.c.orig Tue Feb 13 05:05:20 2001 --- ./usr.bin/login/login.c Tue Aug 7 13:57:27 2001 *************** *** 268,274 **** getloginname(); } rootlogin = 0; ! rootok = rootterm(tty); /* Default (auth may change) */ if (strlen(username) > UT_NAMESIZE) username[UT_NAMESIZE] = '\0'; --- 268,274 ---- getloginname(); } rootlogin = 0; ! rootok = 1; /* rootterm(tty); Default (auth may change) */ if (strlen(username) > UT_NAMESIZE) username[UT_NAMESIZE] = '\0'; >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
