hi kind ppl
i'm using a redhat linux as OS,connected to a LAN.
before i had a *.*.*.69 net address.
now i want to use *.*.*.53.because somebody else is using the 1st address.
at the boot time when init configure my eth0 interface(netaddr *.*.*.69),sends the gratuitous ARP,and got an ICMP message saying that an other host is using this address,so configuration fails.

my solutions:
1/ configuring manually the eth0 interfae after the
the system is up.(ridiculous)
2/ writing a script file.

your welcome help:
which file the init process read from while configuring eth0? i searched in the rc.d directory and its subdirectories but i did not found

many thanks

Redhat stores IP info in /etc/sysconfig/network-scripts in files named icfg-<interface> where the first one is usually ifcfg-eth0 (first ethernet NIC). You can edit these files with the correct information and so long as you don't have DHCP enabled the address will be the same after every boot.

You can test the change by typing "service network restart" then running ifconfig against the NIC to see if it is OK rather than doing a full reboot.

hi again

i'm not using DHCP protocol .thank you so much for help.
thanks

Whenever I need to find a file containing some verbage, I usually try the following.

1. Go to the lowest level directory that you think contains the data. In this case, I'd suggest "/etc" for you.

2. type
In your case, I'd suggest either "route" or perhaps the bogus IP within the quotes. Of course, you can skip step 1 and put the directory in in place of the ".". The word "xargs" is mandatory for this to work.

well, instead of using xargs for such a silly task, i'd suggest you use -R (for recursive)

cd etc ; grep -R "Quakeboy02 just likes typing more and more" *

Thanks for letting me know. I just got back into Linux/Unix after being away for about 10 years. I don't remember grep having that function back then. Of course, it could have, but you weren't there to correct me.

hi nice folks

i thank you all so much for informations

thanks
