View Full Version : Unable to get F9 to get on Internet
11th March 2009, 06:58 PM
I am having trouble getting F9 to connect to the internet via Firefox. I can can get to the internet via ping ( both ip address and www.whatever.com) so it appears that DNS is working. But YUM is not working-error 110 connection timed out. I have disabled the firewall and SElinux
I had a similar problem when I was loading F10 and Scott pointed me at a fix that requires me to get the dnsmasq update but with yum not working I am at a standstill.
Any suggestion would be welcome.
Thanks in advance
just discovered that when I use an ip address instead of www.yahoo.com it works....so dns is suspect again

Open a terminal window and type
to see what dns nameserver(s) have it set for.

I would try commenting out the nameserver 127.0.0.1 line first by putting a semicolon in front. If things don't improve comment out the second or third nameserver lines, until you find the ones that work.

All Thanks alot
I researched some of the threads and here is what I had to do to get it working.
Sidhart Seth said to do this:
add these lines to your sysctl.conf
Sailor said to do this:
you might want to disable ipv6 in firefox...
type "about:config" in the firefox address bar...search for ivp6 and make sure it is disabled
I did these both at the same time so when I saw that it was working I backed them both out and did them one at time. The edit to sysctl.conf was the one that seemed to get it working. I just wanted to drop a note for the next poor sucker who was trying to figure this out.
Now can anybody explain (Sidharth Seth) why the edit to sysctl.conf caused it to work? I hate not understanding why the fix worked.
Once again Thanks

net.ipv4.tcp_moderate_rcvbuf this is "dynamic right sizing" wherein your IP stack adjusts the windowing sizes based on round trip time,
net.ipv4.tcp_default_win_scale, is another IP stack tuning method that adjusts the window scaling size, I'm guessing yum for whatever reason doesn't like having those tuned by the operating system, it looks like he has had you disable these features.
of course that's all a wild guess, maybe ask sidharth seth?
