This is done by matching the answer of a query to whois.arin.net (ANICHOST) against specific keywords defined in { RNICHOST, PNICHOST, BNICHOST, NULL } to find the next server for querying. This doesn't work for PNICHOST anymore since PNICHOST is defined with lowercase letters but the answer of whois.arin.net contains uppercase letters: % whois 211.172.193.100 ... Comment: This IP address range is not registered in the ARIN database. For details, refer to the APNIC Whois Database via WHOIS.APNIC.NET or http://www.apnic.net/apnic-bin/whois2.pl ^^^^^^^^^^^^^^^ ** IMPORTANT NOTE: APNIC is the Regional Internet Registry for the Asia Pacific region. APNIC does not operate networks ... >How-To-Repeat: whois 211.172.193.100 >Fix: Ignore the case when matching the keywords. To see if it works, I use the patch below. A nicer solution would be to create a new library function: char *strncasestr(const char *big, const char *little, size_t len); and use this one :-) The patch converts the contents of the received buffer into lowercase letters befor performing the match. This has no sideeffects since the buffer is not used anymore: --- usr.bin/whois/whois.c.ORI Mon Feb 18 08:42:29 2002 +++ usr.bin/whois/whois.c Mon Sep 16 14:04:15 2002 @@ -287,6 +287,8 @@ s_asprintf(&nhost, "%.*s", (int)(buf + len - host), host); } else if (strcmp(hostname, ANICHOST) == 0) { + for (i = 0; i <= (int)len; i++) + buf[i] = tolower(buf[i]); for (i = 0; ip_whois[i] != NULL; i++) { if (strnstr(buf, ip_whois[i], len) != NULL) { >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
