Re: Problem with Net, Network etc.

["Prem Kurian Philip" <pkphilip@xxxxxxxxxxx>]

Hello Jeff,

If you are planning on using the 486 to connect to the net via
the P166, then you will need to configure the P166 as a gateway.
You will need two network cards or 1 network card and a modem,
on the P166 and have a private network for the 486 and an external
network connecting to the Internet via dialup/ISDN/leased line etc.

For configuring the gateway - do the following
1. Get two network cards or a network card (for the local network) and a
modem for the external network. If however you are using PLIP on the
local network, then you won't need any network card on the P166.

2. Use Ifconfig / linuxconf to configure the devices with the appropriate
IP addresses. If you are using dialup, you will need to specify PPP etc
for the dialup device and you shouldn't specify a static ip address.

3. You will need to configure a default route on the P166 so that all
packets
arriving on the P166 and not meant for the local network can be routed
to the device connected to the external network.

4. Configure the DNS lookup on your machine so that it uses any of the
servers on the net. mostly the range is something like 202.54.6.10
etc...this
could differ in your city.

5. Now you should restart the network by running
/etc/rc.d/init.d/network restart.

6. Connect to the Internet.

7. Try pinging some address on the net and see if there is any response.
If you succeed, go and configure the 486

For the 486 do the following.

1. Use Ifconfig / linuxconf to assign a private ip address in the range of
192.168.1.x etc (there are other ranges) to the machine and also to
setup the default gateway as the P166. Also configure the DNS lookup
to use the VSNL servers.

2.Now you should restart the network by running
/etc/rc.d/init.d/network restart.

3. Try pinging the P166 (the P166 should be up and running ofcourse)
If you succeed and if the connection to the net is open on the P166, try
pinging some ip address on the net.

4. Try using nslookup command to find the ip address of any server
on the net. If this also succeeds, the DNS and the gateway are both
functioning and you are ready to rock :-)

Prem Kurian Philip
