Internet trouble : pinging the device works, nothing else works

Hi

I was looking for a solution for very long for this: I installed arch latest version on my new computer. I compiled the intel e1000 module. I ran the netowrk service of arch.

Here are the result from various commands:

[b]ifconfig[/b]
eth0      Link encap:Ethernet  HWaddr 00:19:D1:B0:A0:0A  
          inet addr:192.168.1.100  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100 
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
          Base address:0x30e0 Memory:50280000-502a0000 

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
[b]route[/b]

        [b] after very long delay:  [/b] 
default         192.168.1.254   0.0.0.0         UG    0      0        0 eth0

[b]route -n[/b]
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0
0.0.0.0         192.168.1.254   0.0.0.0         UG    0      0        0 eth0

The setup is a billion bipac ethernet router configured as PPPoe which has an adress 192.168.1.254. I can successfully ping the device. But I cannot ping any outside IPs like 202.67.222.222 or website like www.google.com since it gives me timeouts. Also running route takes very long delay (see above).

Re: Internet trouble : pinging the device works, nothing else works

Are you using dhcp?

Re: Internet trouble : pinging the device works, nothing else works

This configuration is with static IP. Even using DCHP doesnt help. The above commands report the same thing.

Static and DHCP work equally fine on winXP on this computer

Re: Internet trouble : pinging the device works, nothing else works

Is your /etc/hosts file set up and match with the host name given in /etc/rc.conf?

Re: Internet trouble : pinging the device works, nothing else works

This configuration is with static IP. Even using DCHP doesnt help. The above commands report the same thing.

Static and DHCP work equally fine on winXP on this computer

When using a Static IP, you must define your gateway in the /etc/rc.conf file.  If the address of the router is 192.168.0.254, Define your gateway such as this:

gateway="default gw 192.168.0.254"
ROUTES=(gateway)

Notice the ! is missing in  ROUTES=(gateway)

When using a Static IP you also need to define your DNS server in the /etc/resolv.conf file.  If your router's IP is 192.168.0.254 set it up such as this:

#
# /etc/resolv.conf
#

#search <yourdomain.tld>
nameserver 192.168.0.254

# End of file

If you know the URL of your ISP's DNS server, you can also list it as such:

search hsd1.co.comcast.net

in my case.  Check these two items, and see if you have any luck.

To see if you have a gateway problem, or a DNS problem, type 72.14.253.104 into the address bar of your favorite browser.  It should take you to www.google.com as this is the IP address of google.   If that doesn't work, you probably have a gateway problem.  If it does work, type www.google.com into the address bar of your browser.  If that doesn't work, you have a DNS problem.

Hope that helps.

Edit:  Some of the info I gave above is redundant as I originally typed the above while you were entering your last post.   I hadn't seen post #5 until after entering this post.  Try this for your  /etc/hosts file

#
# /etc/hosts: static lookup table for host names
#

#<ip-address>    <hostname.domain.org>    <hostname>
127.0.0.1        localhost.localdomain    localhost jj
192.168.1.100     jj.localdomain        jj

# End of file

Re: Internet trouble : pinging the device works, nothing else works

Now i can ping the IP address of google pudge gave me bu i cannot ping the target www.google.com. So i guess I need the DNS functions to be working.

# Generated by dhcpcd for interface eth0
search 
nameserver 192.168.1.254

This is my resolv.conf . My DHCP servers ARE given in the router. So shouldnt that be enough?

Re: Internet trouble : pinging the device works, nothing else works

no, copy the DNS servers out of your router and put them into resolv.conf and it should work.

I had to always manually add my DNS servers even on windows OS's for my internet to work with a static IP address.

the DNS servers IP addy is normally in the router information section. all u need do is copy and paste that into resolv.conf. Reboot and everything should work.

Re: Internet trouble : pinging the device works, nothing else works

No luck with entries in resolv.conf. Pinging www.google.com makes the terminal freeze and when I killed it it gave me no message.
