lan on mandriva le2005

[Guest angelz]

I just installed the hyped-up mandriva 2005 after formatting a mandrake 10.1 installation, and to my surprise, even though kde shows that i'm connected to the lan, I can't seem to send/receive any packets (mozilla, nslookup, etc.).

 

dmesg shows something to the effect of buffer overruns (something to do with buffers, i forget).

 

I'm using a static configuration, with hotplugging disabled (if i enable it, kde says i'm not connected anymore).

 

Any ideas?

I would say that you have not set up your firewall correctly.

 

Open MCC and select security. Then select .. Set up a personal firewall in order to protect the computer and the network

 

Put appropiate ticks in the boxes such as FTP Server and POP and IMAP Server and then click OK.

 

In the next window make sure you choose your correct Net Device at the bottom and again click OK.

 

Let us know how you go so we can help further if needs be.

 

Cheers. John.

Weird. I just rebooted into mandriva and all was fixed. (I had done this 2-3 times already but... *shrug*). Anyhow, the problem's gone now :).

 

Thanks, John. I looked into the firewall settings just incase, and there wasn't much to do there. It was already set to 'no firewall'.

[AussieJohn]

I am glad it is now working but I would NOT leave it at No firewall.

I personally use the two settings I suggested and I have no difficulties surfing the net or getting my email.

You will be heck of a lot safer that way.

 

 

 

 

Cheers. John.

One reboot was all it to shake it right up again.

 

Here's the dmesg:

# ping 127.0.0.1

What does this imply? (I reset the firewall to your recommended settings, John, but to no effect)

[AussieJohn]

Try going into MCC again, into Network And Internet then into Set up a new network interface (LAN, ISDN, ADSL, .. In New Connection make certain you select LAN even if you are using an ADSL Modem and using its Lan port

Go next and make sure to select etho

Go next again and select Automatic IP

Go next and place a tick in 1, 3, and 4 choices.

Go next and give a host name of your choice or leave it blank.

Go next and then next again.

Put a tick in YES where it asks if you want to connect immediately then click next .

 

I realise you may have done this but this just to be certain that you are setting up properly.

 

 

I hope it helps. John.

John, the connection comes and goes. I mean, I left the machine running for around 3-4 hours.. returned to find that my network wasn't responding. Reset my eth0, and I could send packets again. What's up with that?

 

P.S. I followed the procedure you outlined above... it's the same I used before, but I carried out the procedure again just in case. This was around 7-8 hours ago.

[AussieJohn]

I think you might have a hardware problem somehow. They are usually the only things that cause random changes, from my experience. Anything from memory, modem/router and even mainboards.

 

Cheers and good luck. I hope it stays fixed for you. John.

i have the exact same problem.

 

After a few mins of internet inactivity, my connection seems to drop, but i can still connect through vnc/ssh. I just did a clean install of mandriva 2006, i used to run 10.1 and it all worked fine.

 

I am running a DCHP router, and it's getting hostname/ip from this router.

 

Having read this forum, i have disabled ipv6, and checked the force no APIC. But i am still getting these messages:

Oct 17 13:51:48 linux kernel: printk: 33320 messages suppressed.

ifconfig shows this:

my network card is RTL-8139, onboard. It's using module: 8139too

 

My still connection keeps dropping.

 

I am about to try the 'Force no local APIC'

 

Anyone have any other idea why it's happening?

 

 

edit: after reading another forum, i shut down the Lisa Service, and it seems to have stopped all the error messages and hopefully the interface dropping.
