I am very new to networks (building them vs using them) and I occasionally
still have minor problems with linux once in a while (not a true expert by
far). I am in the process of setting up a tcp/ip network with a few linux
systems. I am about to install the NICs. If there were to be problems with
their installation how can I tell the difference between that and problems
with the network itself? Say a bad cable or a mistake in my setting up of
the network on a box (leaving something out of hosts, resolv.conf, etc and
just not noticing). Thanks.

Do a netconfig and try again. The numbers don't look right - what's the
broadcast address? From the looks of it, it's supposed to be
111.112.113.255.
Also, add the name/IP address of the gateway to /etc/hosts. This is most
likely the reason for the delay in telneting/ftping.

i'm guessing that you're using masquerading to do this...

masquerading requires a patch (special module) to run ftp, because ftp
protocol connects back to the client on various ports. depending on
your install, you may already have the module installed, you only need
to enable it. if not, you may need to recompile the kernel.
i don't remember the exact name of the module, but i think it's called
something like
masq_ftp
hope this helps

If you have two routes to the Internet you should probably be running a
routing daemon. It will communicate with the routers and automatically
update the routing table with the best routes.

Date: Wed, 11 Aug 1999 23:31:18 GMT
I am running Red Hat 6.0 and I am having trouble connecting to my school's
network. My school has an NT network that uses DHCP and WINS. I have
setup my interface to use DHCP but when Linux tries to detect IP addresses
on boot, I get a "failed" message.
I do not have any static DNS server addresses I can configure so my system
must be setup to find them dynamically.
Few questions:
What is pump? I noticed 6.0 uses this instead of dhcpcd.
Do I need to do anything special for WINS to works?
I am very new to DHCP and WINS in Linux so please forgive my ignorance and
any information you can provide would be helpful.

I have this net setup:

IPX NET F7700A01
LAN B: 192.168.2.0/24
IPX NET F4800A01
I have them communicating using two Linux boxes, luna and rocket.
Luna: eth0 192.168.2.172

Rocket: eth0 192.168.185.1
WANPIPE 192.168.85.2

Netware2: 192.168.185.33
I have the Netware servers talking now using IPTUNNEL PEER=192.168.2.91
and 185.33. Works great, but I will run into a problem with IPX between
networks that don't have their own Netware servers.
Does anyone have information on the IPTUNNEL program ? If I could put

To determine whether a NIC is configured as you expected, type ifconfig. If
the settings look correct, that is there is a hardware (MAC) address and an
IP address for both (lo) and (eth0) for example. A working NIC will responds
to an ICMP ping message (ping 127.0.0.1). If this works, then ping the IP
address you assigned to the NIC (ping 10.0.0.1, for example). If these both
work, then try pinging a neighouring IP addressed device on your network and
on the same subnet. If this works, then ping a device outside your network,
say on the Internet, assuming you are connected to the Internet when you
attempt this portion of the test. If this is successful, then you can eat a
pizza and drink a Coke. :-)
Good luck!

I had the exact same problem with Netscape 3.0 and 4.something in Win98.
I was told that I have to not use the proxy settings in Netscape, so I
clicked "No Proxies" in the 3.0 version and now it works fine. (My 4.0 needs

Don't know how this applies to LINUX, just to Netscape.

: Yes, it is possible. Whether or not your cable company will allow you to
: have two public IP addresses at the same time is less certain.
I'm sure they'll be happy to rent you a second IP address. What might not
be certain is whether they'll let you run IP masquerading to let several
machines look like they have one IP address to the Cable company. I've
heard that some Cable companies don't like it.

Subject: Re: RH 6.0 pump not getting IP via DHCP from Cisco 675

Unfortunately I can help solve this problem however I wanted to voice
a "me too". I've been trying to get Pump to work with my school's network
but it will not acquire an IP via DHCP from the server. Any help would be
appreciated.

Well done, Yousef. Let me ask you something. I'm in the same spot you
were in. I'm statically connecting to a DHCP server, @home, and like
you, everything's behaving so far. What is the advantage of re-
configuring to the DHCP protocol? I know there's got to be a good reason
or two, but I've not been networking long enough to know.
Also, did you change any of your other network settings? In Windows with
DHCP enabled you don't even provide an IP gateway. Same with linux? I'm
using RedHat 5.2. Thanks.
