To everybody,

Recently I found out that there is actually a switch under my building which is used to connect my XP box to intenet.

I remember last time someone has asked me to "tracert"( in XP box) and testing the result.

Hm... until today, which is already about 1 months, my LINUX RH Enterprise ES still unable to connect to the internet.

Below will be my system specs:

Celeron 1 GHZ
320 MB RAM
2 NIC(s)
2 H/d(s) Maxtor 7200
Dual Boot --> XP PRO & RH Enterprise ES

I tried DHCP, and also manually insert my IP(provided by my ISP), but seems not work~~~ what can i do now?

your helpful will be very much appreciated~~~

Sad Adam~

Have you tried anything from my last post?

MrKnisely

we need to see the actual output of the tracert -
tracert www.google.com > C:\tracert.txt
will make that nice and easy - just post the contents of the tracert.txt

The switch in your basement, are you SURE it's a switch and not a router?

If it IS a router, I am wondering if this is anything like this
thread? Try installing the pump client just to be sure.

The other thing I realised is that we havent got the results of an ifconfig (on the linux machine) yet - could you do that? I just want to make sure it recognises both network cards.

If we're working with a router it's a stupid one... Read my posts on the oddities of the IP/Subnet issues.

We've got some STRANGE things happening here.

I'm betting that a tracert off the Win box will bomb.

MrKnisely

It will - I forgot to read the post history. He needs to use tracetcp, which I hope should work

PS : I'm going to look again at what you said about the odd behaviour, but it seemed to make sense to me at the time I wrote it

Jeez this is confusing. I see what you mean now -
And yet his computer is connected to a switch in the basement.

This doesn't make sense unless the ISP owns the switch in the basement, which seems unusual. Would an ISP be willing to hand out IP addresses willy nilly? (assuming some thoughtless person stuck a switch on the end of a line from the ISP) I guess it might, considering everything is in the local subnet, but it seems unusual (what else is new)

[Edit - The ISP does own the switch in the basement -
"Yes, the other end of the cable is pluged into the wall.
My ISP didn't provide me any router or modem."]

Look at the info regarding the subnet masks and addresses. The IP they are giving him is the network number for his subnet, not one of the usable IP's. Beyond that, the default gateway he is getting is on a completely seperate subnet alltogether.

It just doesn't make sense. The only thing that makes sense is that and ISA proxy exists on the network and that he is having to authenticat with it to get out to the internt.

If that's the case, try to get to the internet and then when you get the password page go to a command line. At that point type: netstat

You'll get a bunch of output. Look in the 3rd column for something like computername.domain:8080. The 8080 is the main thing too look for. Once you find the 8080 note the computer name and try to ping it; note the IP address. Once you have that we can try to see if the utility I spoke about earlier that allows linux through a M$ authenticating proxy will work.

Best of luck!

MrKnisely

Thankyou for everyone who helped me.

Here I would like to say thankyou to everyone who ever help me, Especially urzump, Mrknisely.

Sorry for never reply you all in such a long time. This is due to I was sent to another province in Beijing China by my company for working purpose.

I will try to reply you all as soon as i can while i'm back to my China home. thankyou very much!

~Anix~

To Urzump & Mrknisely, still remember me? I'm Anix from China here. Guess what? I'm sending this reply from with using Linux!!~~ hehee~~ Finally i can online with using my Linux Box~

Guess what I did for this? the answer is "Dissable Linux's Firewall"~~!!!

Wow man, previously my Linux cannot connected to the Internet is because of from the Linux Firewall setting, I didn't set my eth0 and eth1 as the device which can pass through the firewall settings. No wonder I just cannot connect to the Internet successfully with my Linux platform.

Anyway, thanks for both of your help and the rest people who ever helped me before.


Anix

That is wonderful news!

It still does not explain all the strange things happening with the IP addresses/routing, but if it's working lets not try to fix it.

I hope all the work was worth it. I know I've switched all my machines to Linux. I still have one that dual boots Win2k, but I only use that to web into my Cisco827. For some reason the Java plugins for Linux browsers won't display it properly.

Thanks for the update.

MrKnisely

MrKnisely,

First of all, it is nice that i can read your reply again.

Now i have another questions. My house have two computers. One is Win98(my dad is using), and the another one is Dual boot (Xp + Redhat 8.0) <-- i'm using

Previously my dad's win98 is sharring the internet connection from my dual boot PC with the specification below:

My Dad's PC:
=========
- win98
- 1 NIC

My PC
=====
- XP + Redhat
- 2 different brand of NIC (D-Link & Realtek)

So last time i'm using WinXP platform and one of the NIC to connect to the internet and the another one to be the middle media that connects with my dad's pc.

So may i know how can i do this in my RH 8.0?

Anix

I'm sure it can be done; however, I do not know Redhat8 very well. I've always used Debian for my Internet Connection Sharing machines.

All you should need to do is address both interfaces, enable routing in the kernel, and define any firewall rules.

I'd guess there would be some howto articles on the internet for this; have you tried searching?

As it stands now, what happens if you connect your Linux box to the internet and configure your dad's 98 box to use the addres of your other NIC in your Linux box as its default gateway?

It may routee already since you have dismantled your firewall.

Cheers,

MrKnisely

<rant>Why does everyone forget the h!</rant>

As for the bridging, I did some work on a redhat machine recently and seem to remember a GUI config for that. Otherwise, you will have to manually configure the bridge. If you have to do that, take a look at :
http://bridge.sourceforge.net/howto.html

I'm here to solve your question. I gave a wrong information before regarding to my gateway from my very previous post, and here is the correct one: [note: the correct gateway should be 192.168.22.1]

IP Address..........: 192.168.22.2
Subnet Mask.......: 255.255.255.0
Default Gateway : 192.168.22.1
DNS.....................: 211.147.192.1

I wrote a wrong gateway to you all since last time, and I think this is why it makes MrKnisely and Urzumph confuse and feel strange to it. So, I think the above corrected information will solve your confusion.
