I cannot use yum in this situation. I can access

1. Q: Networking (or DNS) seems really slow and fails often (Updated 2 January
2009)
A: If Fedora 10's networking seems slow or you get frequent network connection
failures (when other Fedoras or other OSes were working just fine on your
machine), then you're probably hitting this bug.
Here's how you can work around it:
1. Open a Terminal.
2. Become root:
su -
3. Make sure that the "dnsmasq" program is installed (it usually is, by
default, in Fedora 10):
rpm -q dnsmasq
If that says "package dnsmasq is not installed", then you need to install
dnsmasq, by running the following command:
yum install dnsmasq
4. Now, you have to find out which network interface your machine is using:
route -n
You'll see some output that looks like this:
Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0
0.0.0.0 255.255.255.0 U 1 0 0 eth0 0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0
The eth0 there (the furthest bottom-right text in the output) is the name
of the network interface I'm using. Yours might be eth1 or something totally
different. Just remember it for the next step.
5. Now create a file called /etc/dhclient-<your network interface>.conf. For
example, if your network interface is eth0, the file would be called
/etc/dhclient-eth0.conf.
You can create the file with this command (assuming your network
interface is eth0):
nano /etc/dhclient-eth0.conf
Then make this the only line in the file:
prepend domain-name-servers 127.0.0.1;
And then save the file and close it (Ctrl-X then Y).
If you have both a wireless and a wired network connection, you will have
to do this step once for each of them.
6. Now start dnsmasq:
service dnsmasq start
And make sure that it will start every time your computer starts:
chkconfig dnsmasq on
7. Now restart your network connection:
service NetworkManager restart
And now things should be as fast as normal again. You might have to restart the
programs that you're running for them to pick up the changes that
NetworkManager made when it restarted.
2. * IPv6
You might notice that your browsing through Firefox is a little slow on Fedora
10. This is because Firefox 3 has enabled by default IPv6 which causes Firefox
to first resolve an IPv6 address and after the connection fails it switches to
IPv4. To change this setting type:
about:config
and in Filter box type:
network.dns.disableIPv6
Right click on it, select Toggle and change its value to true. Restart Firefox
and you are ready!
