- delint (void casts, shadow warning on port)
- always cast to unsigned char for isfoo() macros, not sometimes.
- save errno to avoid reporting random error value.
- use warnx() when the error is indeed unknown.
- use getprogname() instead of __progname.
- make all locals static.
with one that is KNF, has ipv6, better error
handling, and recursion. I settled on OpenBSDs.
Christos found some nits and had me commit as
is. Christos will follow up with fixes shortly.
whois.networksolutions.com is just wrong -- it only returns information
for Network Solutions domains.
whois.opensrs.net is a bit better -- it returns information for OpenSRS
domains, and otherwise recurses to the correct whois server for other
domains -- unfortunately it is not canonical, and cannot be construed as
"correct." Other recursing proxies include whois.geektools.com and pallas.
eruditorum.org, neither of which is "official" either.
For good or for ill, we go back to whois.internic.net, which is the canonical
source for this information.
whois.opensrs.net, which does internal recursion for domain data.
Network Solutions' server recurses on only _some_ registries, and has the
damned disclaimer and advertising on no-match results.
the WHOIS service, again. New target: whois.networksolutions.com
This program should be replaced with one that does WHOIS++ so that it
can hit all the registries for data.
