Help - network problem

[eikelmt]

Hi Guys

 

I need your help.

For the moment I am running mdk10 off.

 

My network config is like this:

eth0 - internal- 192.168.0.1/24

eth1 - internet- 10.0.0.1

ppp0 - pppoe adsl connection

 

Problem connecting to internet, stay connected and internet connection sharing.

 

Symptom:

No internet

Cannot connect to localhost.(webmin,ping and xserver is affected).

pppoe adapter will still connect.

Adsl-status shows:adsl-status: Link is up and running on interface ppp0

ppp0 Link encap:Point-to-Point Protocol

inet addr:4.62.200.210 P-t-P:4.62.200.1 Mask:255.255.255.255

Glxgears gives only 12 FPS and when network is working 780FPS.

 

Error message:

connect: No buffer space available.

 

This is from my syslog:

Well the nexr funny thing is when I leave the pppoe up and running it will re-connect after a while.

I am going also to try to use ethereal to capture whats going on with my pppoe.

I contacted the isp they asked me of course about my OS and when I said Linux, well have fun in hell.

i hope i got the message: you can`t surf the net, while ping etc. works.

have you tried accessing the net without a firewall enabled? have you given access to the internet for the different users as root? (both can be done via mcc). try that first. if that doesn`t help, please give us some information on your networking-hardware (eth0/eth1 card, adsl-modem type) and post the contents of your ifconfig-eth0 file. :)

[eikelmt]

yes I have tried to de-select the firewall. eth0 is Netgear and eth1 is 3com 940..

They are working fine. I just have to wait for a while and -- hey I am reconnected.

Then while I am writing a post like this I am disconneted again.

here is my ifconfig when everything is fine:

please post your /etc/sysconfig/network-scripts/ifcfg-eth0 file.

did you experience the same problem with another operating-system or other linux-distro (just in case you have tested some others) or does this only happen in mandrake?

[eikelmt]

Hi Artic

 

I have not tested it with other OS(I dont have any)

this has been working fine and everything seems to be fine as long as I am connected.

I have tried to fine out why I am getting disconnected.

 

here is my ifcfg-eth0:

BOOTPROTO=none

DEVICE=eth0

MTU=""

NETMASK=255.255.255.0

BROADCAST=192.168.0.255

IPADDR=192.168.0.1

WIRELESS_ENC_KEY=""

NETWORK=192.168.0.0

MII_NOT_SUPPORTED=yes

ONBOOT=yes

 

ifcfg-eth1:

 

GATEWAY=10.0.0.1

BOOTPROTO=none

DEVICE=eth1

MTU=""

NETMASK=255.0.0.0

BROADCAST=10.255.255.255

IPADDR=10.0.0.1

WIRELESS_ENC_KEY=""

NETWORK=10.0.0.0

MII_NOT_SUPPORTED=yes

ONBOOT=yes

 

 

Thank you

[arctic]

try the following in both ifcfg-files: change your

 

BOOTPROTO=none

to

BOOTPROTO=static

 

any progress?
