setting up static addresses

sde · 11-08-2003, 05:01 PM

hey all,

i just installed debian and i'm not sure what's wrong with the network.

i use a linksys router. i can ping the gateway, but i can not get out.

i did an ipconfig /all on my xp pro box to detect the name servers, and i entered the same nameservers into my resolv.conf

still, i can not ping external addresses.

the /etc/network/interfaces is setup as follows:

Code:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
  address 192.168.1.101
  netmask 255.255.255.0
  network 192.168.1.0
  broadcast 192.168.1.255
  gateway 192.168.1.1

any insight would be greatly appreciated.

thanks!

Do you use dhcp for your windows box? if so then you can set linux up for dhcp.

i want to set everything up static though.

Honestly, it's easier to setup everything though DHCP. Just assign an address to the MAC for the computer in DHCP, and it will act just like a static address, only with central management.

But, assuming you still want to do everything static, I'd guess the problem is in the network translation occuring in the Linksys as opposed to on the Linux box.

Have you tried pinging IP's directly or are you specifically trying to resolve by name?

There is nothing wrong with your config that I can see (though I may be missing something). While I don't think DHCP should make a difference, enable it and see what happens. If it starts magically working then there is something different between your static and DHCP configured addresses.

Is it possible that you have another machine already assigned the .101 IP? What is the IP for your XP box?

well it still isn't working for me.

i spent about an hour last night trying dhcp, and messing with my nameservers a bit.

i can ping the xp pro box, and they are in fact on different ips.

could it have to do with my /etc/hosts file?

It could, but you don't need to touch it.

Can you ping external IP's, or is it that you can't get to www.google.com?

sde · 11-12-2003, 06:54 AM

no external ips or domain names work.

Belisarius · 11-12-2003, 09:01 AM

What does your resolve.conf look like? And for that matter, your hosts file

sde · 11-12-2003, 09:15 AM

resolv.conf looks something like this:

Code:

nameserver 24.24.24.24
nameserver 24.24.24.25

and i'll have to copy the hosts file when i get home tonight.

From what you're saying, your /etc/resolv.conf or /etc/hosts file don't come into play; they would only help in looking up domain names, not pinging valid IP addresses.

At this point I would check your router config; go to http://192.168.1.1 and check to make sure that you don't have a MAC address filter or something else that would block your .101 address from going outside the router.

i am stumped! lol .. i got my mac back up and running and it can connect with the ip i was using for the debian box, so i don't think it's in the router.

heh, so lost. think i need a n00b distro.

sde · 11-15-2003, 06:47 PM

here is my latest progress ..

when i ping www.codenewbie.com,

it is obviously resolving the ip because the lines after that say:
[shell]# ping www.codenewbie.com
PING www.codenewbie.com(199.236.4.162): 56 data bytes[/shell]and then it just hangs.

have you tried pinging your gateway? to see if you can even reach that?

sde · 11-16-2003, 08:37 AM

yeah i ping the gateway just fine.

things got stranger. i installed Suse, to see if i could get it going last night.

since suse installs x-windows so nicely, it booted up in graphical mode. i open up my browser, and bam, i'm at the suse website.

so i open up the shell, and i got the same results. i can only ping the gateway.

stupid me should of thought earlier to try pinging outside from my xp pro box, which i am not able to do. so there must be a setting in my router not allowing packets to return.

i thought it was Block WAN Request, but apparently i'm wrong.

anyone know the linksys router well?
