hi,

my box runs fedora 3, ntl 1mb broadband(cable/adsl) with ethernet connection.

can ping various sites. traceroutes ok but cannot broswe from web browsers(epiphany, firefox, konqueror)!

can anyone help me what i need to do?

did yah try adding a default route to your gateway for example your router
route add default gw 192.168.1.1
but make sure it gets added to the right adapter not eth0 if your using wireless
It worked for me, but i couldnt even ping!!

koolgentoo · 04-15-2005, 03:34 PM

there is no router for my system. wht ip addres should i give for default route?

anyway it is pinging though so the packets are being transfered (icmp)

so it is the http requests are failing.

should i config the firewall???

I just configured a wireless card on a Mepis Linux system. I can ping yahoo and google, but I can't use http. When I use firefox, the website is located but then the status bar keeps hanging at "Waiting for reply..." forever.

what is the status of proxy settings.?

also chk the nslookups...

comprookie2000 · 04-15-2005, 07:09 PM

Also check /etc/resolv.conf

claytonmagnus · 04-15-2005, 09:50 PM

Okay, here we go:

Proxy settings: none in the KDE control center (I don't know where the file is and too tired to look for it), none in firefox.

nslookup works fine. I tried yahoo and another site and got a bunch of ips.

The contents of /etc/resolv.conf are as follows

Code:

search [my network/ESSID name]
nameserver [router address]

Now these settings are obviously wrong. I'll remove them. My router isn't set-up as a DNS.

It obviously resolves ip addresses. The problem with it is that it either doesn't receive the content after it sends the request for it (or it sends the wrong request). Or something is blocking it. Firewall? Why would a firewall block HTTP? Anyway, a quick look at a gui firewall shows that there are no blocks to HTTP.

quick postscript: removing the lines resolv.conf make it unable to resolve internet addresses in firefox.

BTW, I have a Mandrake 10.0 laptop that has no trouble connecting to the internet through wireless, which is what I am attempting to do with my problematic desktop.

I am having a very similar problem. I'm running Fedora Core 3 with wired ethernet card. I can ping servers, ping domain names, use dig/nslookup, etc.. My servers (SSH/HTTPD) can accept connections from the outside (local network/WAN) and serve up pages etc. without problems.

However, any program that needs to resolve a domain name (outside of ping/nslookup) in order to get content off of the net fails. Lynx, Firefox and Yum all fail to connect to domain names. The server is actually behind two routers (one at 192.168.0.x and one at 192.168.123.y - the server is within the 192.168.123.xxx subnet). When using DHCP, I can browse without problems, but using a static IP address seems to throw something off and I can't figure out what is going on.

I have IPtables turned off. My eth0 is the only net interface (aside from loopback). I have the right DNS servers in resolv.conf. Here is my route information:

Code:

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.123.0   0.0.0.0         255.255.255.0   U     0      0        0 eth0
169.254.0.0     0.0.0.0         255.255.0.0     U     0      0        0 eth0
0.0.0.0         192.168.123.254 0.0.0.0         UG    0      0        0 eth0

I checked both routers to ensure that no firewalling that I can detect is going on (one a WRT54G and the other an Actiontec GT701-WG). I have a windows box (this one) in the same subnet as the fedora server also running a static IP and it works fine.

I cannot figure this out; I have used a linux server with static IP and Fedora 2 in this config without problems. Help is appreciated. Thanks, Jesse

Your problem is different from mine. I CAN resolve IP addresses (Firefox finds the page, and then just says "waiting for reply..."). So responders should treat our posts seperately.

did u tried to use your ISP's dns numbers?

greenmachine · 04-18-2005, 04:43 PM

Clayton is right - firefox on my machine hangs at "connecting to ...." with IP address OR domain name, not "waiting for reply."

buzz3953 · 04-18-2005, 04:48 PM

Don't know what the exact cause is but it is dns or proxy related....chances are not proxy as usually would be set in the browser itself and what are chances you had it set up without knowing it in each browser....go dns...what type of connection and should your settings be assigned by dhcp or does your isp assign them....??? also you could perhaps just plug in their dns server addreses but if they change you may be pooched again dow the road...

Well, the trouble is that my laptop (running Mankrake 10.0) connects wirelessly to the internet without any trouble. Your suggestions again would help if I am having trouble resolving name addresses, but I have no trouble doing that. My thinking is that it is either of two things:

I am firewalled off through a setting that I can't see. OR My wireless card would not accept incoming HTTP traffic for some encryption reason.

claytonmagnus · 05-01-2005, 06:04 PM

Well, it's solved. I removed MEPIS Linux and just put Mandrake 10.0. Then after a long battle I was able to make wireless work. I followed instructions on the Ndiswrapper wiki for Mandrake 10.0, but there is one crucial point they didn't mention. The function that searches for hardware is lspci, and I didn't have it. Mandrake had lspcidrake, which is not as good. I edited the perl script to use lspcidrake, but it didn't work. I found the latest version of lspci, put it on a floppy, and then transferred it to the other computer. Another problem I had was with properly setting the nameserver. In the end, I was able to access the internet properly after all.
