Thumbs down Slow DNS search +firefox +FC5 [solved]


Hi
I've got problem with web browsers. Both firefox and konqueror uses a lot of time for saerching address of web pages (I think it's about DNS). After it get DNS resposne page is loaded in 2 or 3 secounds usually.
On my windows everything is OK.
I already tryed adding proper DNS in network configuration. But I didn't help.
I serched both firefox and linux forums but I didn't find anthig usefull. Googling also without efect.
All this is's quite flustrating.
My computer:
laptop hp nx 9005 with athlon 2,4, 256 MB RAM,
Fedora Core 5
Firefox 1.5.0.2

Anbody has any idea?

Check to see if you have a firewall installed, such as iptables. That may have default settings that are slowing you down if not setup properly.

You may have a bad cable. What is the speed in milliseconds when pinging another PC in your network versus pinging a domain such as av.com? that could be an indication.

Is it a wireless PC? It could be your wireless communication.

Go though the process of elimination.

Cable is ok because it's working good on windows on this computer (I have two systems installed)
No wireless. cable only.
And yes I have iptables installed.

as for the ping
PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.
64 bytes from 192.168.0.1: icmp_seq=1 ttl=30 time=0.949 ms

I am not familiar with the structure of FC5, but in that case if it were SUSE, I would suspect something is going wrong in your resolve.conf file (such as a DNS address being overwritten with a gateway address by your router). That is, you would want to check and make sure FC5 is correctly identifying your DNS servers.

Go through the process of elimination: Stop iptables and try it again to see if that's it. Stop all services except your network service and try it again. Run knoppix from a boot CD and try that - if it works well then there's something wrong with your configuration. Do you have bind running? What DNS server are you using?

Yes it overwrites my DNS. I changed DNS names on router to my ISP DNS and it works better. I don't know why it don't want to work on the other DNS numbers I had (this servers are recognized as rather good) but now works more or less fine.
Thanks for your help
