So this is a problem I've been having for sometime now. And I just decided to see if I could get it resolved.

On my Linux Box when I try to open web sites it will either try to connect forever then say it can't find the server, or it will find the server and say transferring data from the website I'm trying to connect to - sits there for awhile - then at this point it will give me the error message that i can't connect or it will finally connect. This usually takes about 2 to 3 minutes to connect.

This problem is only throught the browser (firefox, epiphany, lynx [command line browser]) no matter what browser I've tried. Connecting to this linux box and transferring files is not a problem at all. I run a SSH and Web server, neither of which have any problems. Connection seems perfectly fine, except when using the browser on the linux box. I have a Windows XP computer connected to the same hub (is actually on a KVM switch with the linux box) that works fine with everything. I also have a Windows 2000 box, and Mac OS X laptop running on the network, both of which work fine [except their running Windows 2000 and Mac OS X ].

Basically I'm wondering if there's some network setting I'm over looking that could be my problem?

I'm "fairly" linux savvy and have been using Linux for about 2 or 3 years now, but have slacked off on keeping my skillz up to date since work is mainly Microsoft now. I have ethereal installed and can create a report if need be.

Things I've Tried:

- changing DNS servers, mimicking DNS servers on my windows box
- chanigng route table entries
- changing route entries to mimick windows box
- various browsers (firefox, mozilla, epiphany, lynx)

Computer Information:

- OS: Fedora Core 3
- NIC: Intel Corp. 82801DB PRO/100 VE (LOM) Ethernet Controller
- Dell 4550 2.4Ghz 512MB RAM

Any suggestions are appreciated. Thanks!

Can I assume that your DSL modem is connected to the hub and your not using a router?
If so can you post the output of ifconfig ppp0?

oh, yea forgot about that part.

I have DSL through Qwest (3Mb Down, 896Kb Up). DSL comes into modem (which is an all-in-one ActionTech - router, modem, etc). From there ethernet to a switch upstairs, then ethernet to switch downstairs (which is where linux box and windows xp box are connected).

ifconfig ppp0 give not output, for device does not exist.

Thanks for quick response.

Does dslmodem.domain resolve to the IP address of your modem/router?

fedora\rhel & Firefox\Thunderbird & 3 Tricks

(1) Try disabling IPv6 if enabled

(2) Ensure SELinux & Firewall\IPChanins are disabled, especially if you don't know how they work

(3) ensure that your DNS \ \etc\resolv.conf has at least 1 DNS entry of yuour ISP, NOT your Router, even if Windows doesn't

(4) If all else fails, download the latest RPM for your app
