if u again get then error then quickly go for

tail /var/log/messages


will give u the the last log and paste that too

hi

i m not able to change the content of this file...

/etc/sysconfig/network-scripts/ifcfg-eth0

it says i dont have permission to change the content of the file or i dont have enought space.

about space.....i have 1.5 GB space left in that drive

i tried ....

chmod -w ifcfg-eth0

but it was of no use...again the permission problem.

how can i change its content?

one interesting thing i find is that.....i m getting ping form 172.16.10.1(gateway) and i m able to open the ISP page when i type 172.16.10.1 in my address bar. but i not able to open any website.

hi there

did u run

su

before trying to edit that file???

if u r still unable to edit that file
then run

service network restart

and post what u get immediately after that at

tail /var/log/messages

regards

hi,
well it didnt work:(

following is the last contents of /var/log/messages

hi there


try this
---------
In Mandrake Control Center -> Network & Internet -> Manage Connections check under the Options tab that the 'Network Hotplugging' option is NOT selected.
--------------

if that fails

set this
MII_NOT_SUPPORTED=no

to

MII_NOT_SUPPORTED=yes

and give it a try

regards

hi,

'Network Hotplugging' option was already selected.

then i tried to change

MII_NOT_SUPPORTED=yes


for no use.

:scratch:

god!its really frustrating now......dont understand what made it run uns and not later on.:(

i think u need to give a try by unchecking that network hotplugging option

yes it is really frustating with these problems

but i have learned a lot after being patient with LINUX

regards

hi,

this morning i tried unchecking the hotplugging option....it didnt work. but now during booting it says.....


Bringing up interface [OK]

one more thing i notice everytime is that....

whenever i change my DNS servers as following in "internet access"

DNS1-203.88.128.7
DNS2-203.88.158.230

but when i click OK button n check again.....then i shows


DNS1-127.0.0.1
DNS2-203.88.128.7
DNS3-203.88.158.230

i dont understand y mandrake changes my DNS server options.(adds 127.0.0.1)

my feeling is that ......problem is here.coz i am not able to open any website....DNS error.

ok. so one problem is now solved!
for the other
edit ur /etc/resolv.conf

put the entries there as

nameserver 203.88.128.7
nameserver 203.88.158.230

and then too if u do not get ur internet working then post again the O/P of

route -n

regards

i changed content of the file /etc/resolv.conf....it didnt work

when i restart my comp.....then content of the file etc/resolv.conf is automatically changed to original.
