>Number: 4497 >Category: bin >Synopsis: Reverse DNS fails for some CIDR *.IN-ADDR.ARPA domains >Confidential: no >Severity: serious >Priority: medium >Responsible: freebsd-bugs >State: open >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Mon Sep 8 12:00:01 PDT 1997 >Last-Modified: >Originator: C. Stephen Gunn >Organization: Wintek Corporation >Release: FreeBSD 2.2.2-RELEASE i386 >Environment: Any FreeBSD 2.2+ machine, including 2.2-R, 2.2.1-R and 2.2.2-R, but not in 2.1.6-R. >Description: Binaries not staticly linked with libresolv.a fail to do correct DNS lookups on certain (not sure which or why) IN-ADDR.ARPA domains. Two CIDR blocks assigned to Wintek that do not work are: 206.230.0.0 - 206.230.7.0 208.13.56.0 - 208.13.63.0 >How-To-Repeat: Login's to FreeBSD-2.2 machines from the IP's on these subnets do show in utmp entries as the IP address not the hostname. Traceroutes for these subnets fail (sometimes) as well. Be advised the "dig", "nslookup" and similar tools give correct responses since they were linked with the resolver that comes with the bind distribution, not the one in libc. >Fix: >Audit-Trail: >Unformatted:
