Sorry if I came across like Barney on Andy Griffith. This one little
machine is it here at wayward4now.net. Nothing fancy, just this machine
hooked to a DSL modem, with BellSouth.net and I have a static IP
address.
hostname: iam.wayward4now.net <---<chuckles at cutesy name>
domainname: wayward4now.net
static IP: 70.145.234.214
netmask: 255.255.255.0
gateway: 65.14.234.23
search dns: dns.asm.bellsouth.net
primary DNS: 205.152.37.23
secondary : 205.152.132.23
If you do something like "dig google.com @205.152.37.23", do you get a
quick response? Do it at least twice, the first response will be slow,
subsequent ones will work from a cache.
Likewise, try against the secondary DNS server address.
This stuff is a piece of cake. I can eat therein. But, the whirlygig
network setup thingie keeps adding hostnames to the localhost line in
hosts. I edit it out, it may come up, it may not. I still haven't found
bind-config and rpm sez I don't have it installed (that bugzilla
report) When I try to de-activate eth0 more often than not, it won't.
I think you're fixating on bind-config. It doesn't play a role in your
hosts file, nor activating ethernet interfaces.
So, I go back into the DSL modem, set it back to not-pasthrough, crank
up DHCP on this end and now I can email. I STILL get DNS lookup failures
though, even with DHCP! WTF? Regularly.
DHCP just configures your side of the network with the data that the
DHCP server says to use (as you supplied above). If there's a wonky
DHCP server configuration, you might get told to use a DNS server that's
incorrect, or not even get some of the information that you need.
I have the NetWork Manager and NetWork Dispatcher running. Look at this, it's BACK!
[root@iam etc]# more hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost iam.wayward4now.net
So, one of them is most likely the culprit, not BIND. I thought they
were used for something like wireless? Or, at least for switching
network configurations around for people who use multiple different
networks, but not simultaneously (e.g. work, home, internet cafes). If
you're not doing either, you can probably do without them. I don't have
them, but then I have a modem/router between me and the ISP.
Shouldn't there be a 192.168.0.X entry here?
Only if you have a LAN using those addresses. Or, if you want to fake
things as if you had, giving your machine an interface with a consistent
address.
