Traceroute revisted again

Post by Subba Ra » Tue, 24 Nov 1998 04:00:00



My network configuration has 3 hosts (Linux, NT and OS/2) connected
via ethernet. The Linux system serves as the Internet gateway. I am
using the 10.0.0.x network addressing scheme. The subnet masks are
255.255.255.0

The Linux gateway has 2 interfaces modem and ethernet, for networking.

I have traceroute on my linux system. In the past when I connected
with SLIP connection and did a

$ traceroute -i sl0 tsx-11.mit.edu

< I would get the hop information >

Now, I connect with PPP, since it is given more preference by my ISP.
When I do

$ traceroute -i ppp0 tsx-11.mit.edu

< I don't get any hop information >

The PPP connection is up. I can connect to WWW and so forth.

I also tried,

$ traceroute -s <my dynamic IP address> -i ppp0 tsx-11.mit.edu

< Still no hop information >

When I do,

$ traceroute -d -s <my dynamic IP address> -i ppp0 tsx-11.mit.edu

I get the following information.

traceroute: wrote tsx-11.mit.edu 40 chars, ret=-1
  *traceroute: sendto: Network is unreachable

At this point, I can still connect to the WWW.

Anyone information you can provide to get this working is much
appreciated. Please reply any of the following email addresses.


Thank you in advance.

For Class A network mask should be 8-bit (255.0.0.0).

Linux, NT and OS/2 all support classless internet.

Nope. For Class A network, subnet mask should be
*at least* 255.0.0.0, but can be more.

Actually, the netmask can be just about anything as long as you're
willing to work with some really weird network configurations.
