Network problem!


Recommended Posts

Hi u all!

I have been trying to figure out a problem with a network connection against

Windows 2000 Server.

I am using Linux Mandrake 9.2.

I have been trying the Forums in www.Linux.Net, but without any good respons(they don`t now).

The Network card is a Cnet pro 200, the driver seems to be okey.

The Link light is flashing as it should, i has pinged my own Ip: 10.251.73.33 and the mask: 255.255.0.0.

But when i ping other computers in the network, It finds nothing.

I used "Ifconfig" to check out my own info.

I want to use Linux Mandrake 9.2 as a workstation and to do that it has do be able to connect to a Windows 2000 server machine(Log on and Proxy).

What should i do? :(

how are you getting your IP address... via DHCP or are u statically assigning it to your card?

what is the IP address of your server? If your machines are on a different IP address range, you wont be able to ping each other.

sorry, this may sound simple, just best to check these things first!

peeete is right, you mention no gateway IP address - so if the other machine is NOT on the same network segment you, you will not be able to connect to it, until you have setup a gateway

what does route show?

Also - are you trying to ping by name of machine, or IP address. If by name, what are you using for name resolution??

The Ip-adress is configured manually by myself.

The Ip and the nettmask is at same level as the rest( i used the same adress and mask as on my win 2000 disc, that i use on the same computer).

I have writen in the proxy-adress and the gateway to the Server:

Gateway: 10.251.12.197

When i press connect under the network setup, it finds nothing.

is it some way i can check presisly, if i got connection(except Ping).

When i ping the others in the nettwork, i use their Ip-adress.

The other machine i try to ping got this info:

Ip: 10.251.12.37

Mask:255.255.0.0

This problem reminds me of wrong protocol or something, like Tcp\ip - Ipx.

I hope u all got a solution on this, i am a bit depressed. :cry:

Well, I am here at work, and have my Linux laptop on (but not 'logged into') a Win2k network.

My eth0 is:

eth0      Link encap:Ethernet  HWaddr 00:C0:4F:07:DE:29
         inet addr:148.93.49.94  Bcast:148.93.255.255  Mask:255.255.128.0
         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
         RX packets:2500065 errors:0 dropped:0 overruns:1 frame:0
         TX packets:4947 errors:0 dropped:0 overruns:0 carrier:0
         collisions:357 txqueuelen:100
         RX bytes:232026491 (221.2 Mb)  TX bytes:438917 (428.6 Kb)
         Interrupt:10 Base address:0xfc00

(word wrap makes the "Mask" move down a line... Pretend it is after Bcast.) :)

I can ping my gateway at 148.93.8.1, as it is on the same subnet. Does the result for your ifconfig eth0 look much different than mine? In particular the "UP" on the third line?

hi again Mark!

I have checked what u asked for, and i have found out that i have two connections,

one is named "lo" and the other connection is named "eth0".

i tryed to pinged both of them, i got answer from them both.

The setup on "eth0" is very similar like yours!

i wonder if i should remove the other connection possibiliti "lo", if i should tell me how!

You should not remove lo (actually I'm not even sure you can) as it is the local loopback device. It doesn't actually do much and isn't a physical device. It's used when you hit localhost or 127.0.0.1 in your browser or whatever.

Could there be a firewall somewhere that is blocking pings and/or connections? I don't know if Mandrake 9.2 installs a firewall by default and whether it has some sort of default config.

I now that the school i am building this Linux station has a firewall, but even when

they turned it off for some minutes, it did not work anyway!

I wonder if u guys can tell how fo find out if the network driver has a mailfunction?

I have a disc with a original driver on, but i don`t now how to install it.

I can`t switch network card, the school forbid it.

Does mandrake install a firewall as a default u say?, i am not surprised if the machine is installed as a server! Do u now how to check this very easy?

Figures that I am away from my Mandy laptop... :pinch:

But, even with a firewall, a ping should still work.

Perhaps a ping from the Win machine to the Mandy one will work? (I doubt that it will, but we can try)

To be sure, if you can borrow a laptop and a crossover cable, you can probably direct-connect the Mandy to the laptop (running Win/Lin/whatever) and do some basic functinoality checks that way....

Hi again!

I have been trying and trying to fix this problem, but no luck!

I have tryed to ping from a other computer with Windows on it, nothing.

The windows machine has the same Mask and almost the same Ip, except of the

last number of course.

as i said earlier, this problem reminds me of a problem were it was between 2 Windows machines.

The error there was wrong protocol, Tcp\ip on 1 machine and Netbeui on the other machine.

What is the protocol in Linux called, that has the same qualifications\options as Tcp\Ip in windows?

The teachers are just laughing of me, they say Windows 2000 is better than

Linux mandrake 9.2! :cry:

I hope u can help!
