Lan Tcp/ip Question
Hi Everyone,
Question for anyone who knows much about networking under Debian.
I have two computer one is running Debian Linux. Kernel 2.0.29 and the
other is running Windows Nt Workstation Sp3. Now heres what I'm trying to
get done is the two machines to connect up and let the debian download
stuff off the Nt machine(I'm in the process of replacing the NT machine and
need to do some data transfer.) I've already figured out that I need
samba, and have it installed but it doesn't work. So I was reading through
some of the FAQs when it said to check and see if I can ping the other
machine, so I try that. Both machines CANNOT get any response when they
ping each other, I know the NT machine works because I can ping another
Windows machine on the network. I get what looks like an activity light on
the hub everytime I try something like ping from either machine. But
machines can ping themselves.
Heres the setup
Windows NT machine - ip address 192.168.1.2 subnet 255.255.255.0 no gateway
defined
Debian Linux machine - ip address 192.168.1.1 subnet 255.255.255.0 no
gateway defined
Debian Machine is running a 3com 3c509b(Very close to the best isa Nic I've
ever used.)
I've narrowed my problem down to have to do something with the debian
routing setup.
Heres route and ifconfig information
route -n output

This is the way the output appears after login. I've been manually adding
this line
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 1 eth0
By typing
route add -net 192.168.1.0 eth0
(I do know that this can be done through a script at startup, but I want to
get it working correctly before doing that.)
ifconfig

Local Loopback is working because I ping myself or 127.0.0.1 and I get a
response.
I have tcpdump installed(very handle util.) And when I try to ping I get a
message about icmp: echo Request but thats it.
Like I said I'm very sure this has something to do with my routing table,
but everything I've read or seen about the routing table confuses me more.
Any ideas what I'm doing wrong
Do I have to have a default gateway? And what is that used for? A router?(I
don't have one if so)
Thanks in advance
