need newbie-flavoured help with RH7.1 / Win98 network

Post by to.. » Thu, 04 Apr 2002 09:18:24



I have a network of 5 W98 machines set up in my house, with a RH7.1
router feeding them all to cable, and one RH7.1 workstation also on
the same network for me to learn on.  The router and all W98 machines
can get on the net, but the RH7.1 machine can't.  I'd like to hear
from someone with gentle patience who can take me through what I need
to look for to solve this

Go onto the workstation and retrieve it's IP and routing table first.

ifconfig
route -n

The ifconfig will tell you the currently configured interfaces with the
IP's in use.  I guess you need to look at the eth0 section, make sure
the IP is correct and that the netmask/broadcast values match what the
other machines have.

If eth0 is missing then the card isn't configured yet.  The lo interface
(127.0.0.1) should be there anyway.  In this case we need to let us
known what card your using.

The routing table is needed for decision reasons,  you should have
route to 127.0.0.0, a route to your local LAN and a default route
(0.0.0.0)

If all this is available then it might be the firewall being too
restrictive.

did you configure DNS for the workstation?
like resolv.conf in the /etc directory, IP setting looks ok, maybe it's a
DNS problem....

/etc/resolv.conf

        search
        nameserver 192.168.1.1

which is eth1 in the router machine

do you mind doing a few test for me?
1) try to ping www.redhat.com from your workstation. this is to see if DNS
lookup is functioning for your workstation.
2) suppose you do get an IP for www.redhat.com, do a tracert on this IP,
this will check connectivity and routing settings.
thanks.

agreed,  host is another command you can use.

traceroute may not be a good test as depending on firewall settings, it
may block the packets.

The ping test is valid, see if name resolution works, ie 192.168.1.1
does DNS services.  If it does and it works then it sounds like a
firewall issue.

Found it!
it wanted the name server numbers for the cable providor . . .

one more thing I'll hopefully only have to learn about 37 more times

:-)

thanks much- I _know_ I'll be back

 
 
 

1. Newbie networking on RH7.0, need detailed help

Hi, I have a LAN in my home, with laptop, win,and Linux as clients
sharing a DSL conection. All laptop and windows works fine, but on one
system with Linux, I don't know what to do.

The server used Sygate software, and all the win clients used Sygate as
well, so I have no problem for win.

The gateway is 192.168.0.1, dns is 192.168.0.1, IP for Linux box is
192.168.0.4, network mask is 255.255.255.0.

I am really new in Linux networking, so I don't know where to set it up. I
know that there is a program called network-configurator in RH control-
panel, but I tried to enter the values but failed to activate the interface.
Is that because I entered stuff in wrong place, cause on some field which I
dont understand I just guess. With the above infomations, can anyone tell me
how to set it up in step by step? or prehaps point me to somewhere else??

I am using a netgear FA311, is that suppoted in Linux?
