- Servers listed on the LoC gateway but that failed to initialise the Z39.50 protocol
during tests using the
Library of Congress WWW/Z39.50 Gateway interface are ignored.
Other servers listed as FAIL may have accepted a normal Perl socket request on the
Z39.50 port but failed to complete a Z39.50 connection on the same port. This may be
due to configuration faults on the server or firewalls. isbnsearch tries to use
canonical names in preference to IP addresses for two reasons:
- IP addresses generally have a shorter life than the canonical name
- A DNS failure on a canonical name is easier to detect than a failed IP
address that may or may not have a reverse-lookup name and will usually not
respond to ping requests but will often allow a Perl socket request to complete,
even if the service on that port is down or disabled.
- Canonical names that fail to resolve via DNS are ignored and are no longer
even listed in the server reports.
- The servers listed on this site are a combination of LoC Gateway servers and
Net::Z3950::AsyncZ servers with any canonical names tested in DNS. Every server
in the LoC Gateway page or the AsyncZ DB.txt list on Tue Nov 2 2004 has been
