I checked the current glibc source for this function, and was able to locate it in inet/rcmd.c: /* * XXX * Don't make static, used by lpd(8). * * This function is not used anymore. It is only present because lpd(8) * calls it (!?!). We simply call __invaliduser2() with an illegal rhost * argument. This means that netgroups won't work in .rhost/hosts.equiv * files. If you want lpd to work with netgroups, fix lpd to use ruserok() * or PAM. * Returns 0 if ok, -1 if not ok. */ int __ivaliduser(hostf, raddr, luser, ruser) FILE *hostf; u_int32_t raddr; const char *luser, *ruser; { struct sockaddr_in ra; memset(&ra, '\0', sizeof(ra)); ra.sin_family = AF_INET; ra.sin_addr.s_addr = raddr; return __validuser2_sa(hostf, (struct sockaddr *)&ra, sizeof(ra), luser, ruser, "-"); } Perhaps the failing application should be changed? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
