I know there's lots of posts out on the net about similar issues, I've tried to follow the various bits of advice I picked up while searching (gai.conf/nsswitch.conf/hosts etc).
I've recently upgraded from 1.8 to 2.2 and I've just noticed an issue with name resolution for certain programs under squeeze. I think it must be related to some software preferring IPv6 over IPv4. I can ping, nslookup, dig and host any domain name so my DNS seems to be working. However when I try to use wget or elinks I get:
however if I host or nslookup its fine:
So far I've checked my nsswitch.conf is:
my gai.conf is preferring IPv4 over IPv6
wget will work with the -4 switch, however if I try to force this with edits to the wgetrc it doesn't pick those up.
elinks doesn't seem to work no matter what. All I ever get is "unable to retrieve http://yahoo.com/: Host not found" errors. Even if I try to force IPv4 with the http4:// prefix in URLs. I've added the options set connection.try_ipv4 = 1 and set connection.try_ipv6 = 0 in the elinks.conf with no effect.
Has anyone else had similar problems with IPv4/IPv6 and name resolution with wget and elinks? Do you always have to use the -4 switch in wget or can you configure it to remember it?
