Can't surf but pings just fine

IHGdude · #1 14th July 2005, 07:17 PM

This is a weird one. I am on Fedora Core 3. Using a Netgear GA311 gigabit ethernet card connected by cat5 directly to my actiontec DSL modem. I can ping servers all over with no problems, but if I try to FTP, nothing happens. If I try to use Firefox, I can often get the first page to open (usually slow to load images) but then any link from there times out.

Other pertinent details: I disabled the firewall. ifconfig shows DHCP is working (the DSL modem/router/firewall/DHCP is giving this box valid info).

Ideas? Recommendations?

what is in your /etc/resolv.conf?

IHGdude · #3 14th July 2005, 08:45 PM

I will check. I am not at the machine right now (damned job - cramping my style

) but will post in a couple of hours. Thanks for taking the time to think about this.

/etc/resolv.conf
has
; generated by /sbin/dhclient-script
search domain.actdsltmp
nameserver 192.168.0.1
nameserver 199.181.164.1

So it looks good. I am mystified. I can connect to my local ISP. I can navigate all over their page. Then when I try to go outside, blam - nothing.

ooo. did a ping on 199.181.164.1 and got an error
wrong data byte #17 should be 0x11 but was 0x19
#8 8 9 a b c d e f 10 19 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 21 22 23 24 25 26 27

Now I am trying to ping www.redhat.com and getting nothing back.

I can ping gecko.mozilla.org and get response times in the 80ms range. What gives.

ARGHHH.

More exact same ping errors. Thinking I have a bad card. Will try to take it back and get a replacement. Thanks tejas for your input.

Have you tried adding your ISP dns address to the resolv.conf?

IHGdude · #9 15th July 2005, 04:12 PM

binarykungfu: I haven't tried that. Being fairly new to the commands in Linux, can you show me how to add my 2 DNS servers?

daneel971 · #10 15th July 2005, 04:19 PM

open as root with a text editor the file resolv.conf and add a line starting with "nameserver" followed by the DNS for each one of the DNS you have; save the file, and cross fingers. For me, it worked.

IHGdude · #11 15th July 2005, 04:21 PM

daneel971: Thanks for the tip. I will give it a try and report the result.

IHGdude · #12 15th July 2005, 04:27 PM

Oops. I just remembered: These are my DNS servers. Should I add something else? gateway?

Given the errors I think it may be the PCI ethernet card. I am going to try and swap that at the shop where I bought it for a new one. If that doesn't work........

daneel971 · #15 15th July 2005, 04:31 PM

do you use rp-pppe?
