Thanking you,
zameer ahmed syed

you need to configure your interfaces file.
Depening on your distribution it'll be called /etc/network/interfaces, or something similar.

example:

auto eth0
iface eth0 inet static
address 10.0.0.1
netmask 255.255.255.0
network 10.0.0.0
broadcast 10.0.0.255
gateway 10.0.0.138

Thanx for ur kind reply

Could u please send correct path. iam having Linux 9 version, where i could get correct info or site..... plz kindly reply

linux 9 is not a distribution.
type man interfaces. that will tell you where you can find your interfaces file

I typed man interfaces

but it shows no manual entries for interfaces...
what's next to proceed

Thanq

Hai Siemens,
Sorry for the disturbances,
I found one file in name "ifcfg-eth0" in the path
/etc/sysconfig/networking/devices/

here i am having the following information

DEVICE= eth0
ONBOOT=yes
BOOTRECORD=dhcp
USERCTL=no
PEERDNS=no
TYPE=ETHERNET

IAM TOTALLY CONFUSED
MY BOSS SAID THAT U PLZ RE INSTALLED
BUT I DON'T WANT IT, PLZ SOLVE MY PROBLEM... RE INSTALL IS NOT THE SOLUTION I THINK.....

HELP ME ......

THANQ

ONE MORE THING IS BY TYPING /ETC/RESOLV.INF FROM TERMINAL USING CAT COMMAND IT SHOWS SERVER IP ADDRESS.........

THANQ

Siemens,
first of all iam very thanqfull to ur patience......

Iam providing full information what happened...

ACTUALLY PROBLEM IS...
Here i got some problem reg NIC card, to day i boot my sys then i got a message u r network card has been removed ... and it asks me options llike "keep configuration ", "remove configuration", "no changes". then i select" remove config " option ... i think i can config it manually....

when ever iam trying to activate network card it gives me a message
" cannot activate etho " configuration for etho not found "
"usage /sbin/ifup <device name>" even it doesn't shows me a network card from hardware devices....

I use netconfig command through terminal , here i change IP Address , subnetmask , gateway address , and i clicked on... then i check through ifconfig command there i got Loopback address

now tell me what to do... u have complete information ..... plz don't tell do whatever u boss said......

Hi zameer_india,

be patient and don't be confused...........

Ok, now come to your ethernet card configuration,

I think u might be using Red Hat 9, plz. check it by looking at message show and boot time , and u can even check this by runing these commands

#dmesg |grep version

#cat /etc/issue.net

#uname -r

and show me the output and try to find your self also through these commands output...


now run as a root show me the output of this command
do the following things as a root,

#ifconfig

and now steps to configure network card

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

DEVICE=eth0
BOOTPROTO=static
IPADDR= <enter the ip address of the system>
NETMASK=255.255.255.0 (set it according to ur ip)
NETWORK=192.168.1.0 (set it according to ur ip)
BROADCAST=192.168.1.255 (set it according to ur ip)
ONBOOT=yes
MII_NOT_SUPPORTED=yes
GATEWAY=192.168.1.1 (set it according to ur ip)

#/etc/init.d/network restart

#ifconfig

now try pinging other system on the netwok


--return back ??
