wget resolve host address issue? [solved]

Recommended Posts

I'm pretty smart when it comes to networking, and DNS. But I can't figure this one out. Why is it my machine has issues resolving addresses with wget, but everything else works fine?

 

[jbess@Scooter ~]$ wget www.google.com
--2009-12-22 14:02:47--  http://www.google.com/
Resolving www.google.com... failed: Name or service not known.
wget: unable to resolve host address “www.google.comâ€

[jbess@Scooter ~]$ host www.google.com
www.google.com is an alias for www.l.google.com.
www.l.google.com has address 74.125.65.99
www.l.google.com has address 74.125.65.105
www.l.google.com has address 74.125.65.103
www.l.google.com has address 74.125.65.106
www.l.google.com has address 74.125.65.147
www.l.google.com has address 74.125.65.104

[jbess@Scooter ~]$ wget 74.125.65.99

I've tried wget with the --no-proxy (I'm not using a proxy though), --no-dns-cache, and nothing works. Any ideas? I am running wget version 1.12 on Mandriva 2010. Here is my /etc/resolv.conf:

 

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 10.0.0.1

So, you are using NAT?

What nameservers are assigned to your router?

 

Yes it's NAT'd. I have two Qwest nameservers. I put those in my local box, and it works. So it looks like my router doesn't like wget. The router config hasn't changed, and I have another Mandriva box (2009 Spring) on the network that wget works just fine.

 

I dug a bit deeper, and found a resolution on http://serverfault.com/questions/76421/wget-cant-resolve-host. Basically, the /etc/nsswitch.conf file needed the host line reconfigured to:

 

hosts:           files dns mdns4_minimal [NOTFOUND=return] mdns4

I had to do a "sudo service network restart" for it to take effect, but I'm back to normal.
