Last Call for Net Connection Help

[RAGEAngel9]

Ok guys I'm really frustrated. I've been tryign for the last 3-4 weeks to get online with linux, but I just can't. I don't know why, I have before on the same pc. So I'm asking as a last plea,
Will anyone help me in a step by step way, preferably using Network Configuration? I know I''ve asked for help before but I don't know what else to do. I've tried the networking HOWTO, and linuxnewbie and here and I'm just stuck. So if anyone is willing thank you.


My specs:
Redhat 7.2
ethernet
static IP 128.XXX.XXX.XXX
gateway
3 dns server ips
hostname +dns : resnet.school.edu


I think thats all I should need. SO again if anyone is willing HELP ME!!!
Thank you

Usually redhat will set up the network automatically if you are on a LAN/Cable connection like that. Are you supose to be going through a proxy? Can you ping anything? Are you using dhcp?

[RAGEAngel9]

I've tried Redhats network configurator and it's worked before but I'm not sure where all my information actually goes since there are a few places to put the different things.
Also no proxy.
No dhcp (Just a question isn't that mean a static IP?)
I can ping local only and if give the pc a hostname I can ping it.
Not sure if thats the same thing.

No dhcp (Just a question isn't that mean a static IP?)

DHCP is the Dynamic Host Configuration Protocol (IIRC). Most ISPs use DHCP because it's easier than giving all their customers a static IP, especially if it's a large network.

What about the subnet mask is that the right mask? it might not be 255.255.255.0 maybe they have different subnet for each dorm?

Do you have the ip numbers? try putting the acuall numbers instead of spelling it out, maybe that will work.

Did you say you have your windows box working? Get ALL the info from that machine, ipconfig /all on a windows 2000 box will bring up everything you need. I think on a windows 9x it's winipcfg.

we will get this working!!!

[RAGEAngel9]

Ok I checked ipconfig
I have my IP
I have my gateway
I have my subnet mask
I have my 3 DNS servers
No DHCP
No IP routing
No proxy

Now for boblucci:
I have used the DNS server Ips, I'm just not sure if I have them in the right place.
So where do we go from here?

With a 128.x.x.x IP you should use a subnet of 255.255.0.0

[RAGEAngel9]

Really ?
hmm ok well when I received the info for my connection
it said the gateway should be 255.255.255.0, but I'm
desperate so I'll give it a try and let u know.

[Counterstrike]

Yeah, it's all about subnetting. On an 128.x.x.0/16 network the subnet should be 255.255.0.0.

The subnet of 255.255.255.0 should only be used on a 192.x.x.0/24 network.

Likewise on a 10.x.x.0/8 network, a subnet of 255.0.0.0 is required.

[Counterstrike]

it said the gateway should be 255.255.255.0

If this is what you have your gateway set at, then it will not work. This is not a valid IP. A gateway is a device which transfers information in between two networks (such as your intranet and the Internet).

Let's take a look at your network setup

INTERNET
|
|
v
Internet IP (eth1)
(Firewall machine/router)
Lan IP (eth0 128.0.1.1)
|
|
v
Lan IP (eth0 192.168.1.34)
(Linux Workstation)

Ok, let's say your internal LAN IP is 128.0.1.34 (for your computer). You'd want your subnet as 255.255.0.0, and your gateway as 128.0.1.1. If you have a router (not a proxy), set your DNS servers as your ISPs. Then set your hostname to myredhatmachine.resnet.school.edu. (Replace "myredhatmachine" with whatever you want, this is inconsequential to network performance).
