I've discovered that gethostbyname and gethostbyaddr behave
differently under libc5 and libc6. I'm wondering if either has a bug,
and why there is a difference anyway.
Here's what happens:
Given the following lines respectively in host.conf and nsswitch.conf:
order hosts,bind
hosts: files dns
two nameservers in resolv.conf:
domain clear.net.nz
nameserver 203.97.33.1
nameserver 203.97.37.1
and a PPP link up to my ISP, libc5 and libc6 seem to work the same.
If the link is down, gethostbyname fails in both cases, but h_errno
gives a different error.
libc5: TRY_AGAIN
libc6: HOST_NOT_FOUND
If nsswitch.conf contains the line "hosts: dns", libc6 gethostbyname
gives TRY_AGAIN.
I would prefer not to be told that www.debian.org, for example, is
authoritatively known not to exist, especially if there was just a
temporary problem with the name servers. Should I report this as a
bug against libc6?
