Thanks rohan but our gateway on 24 ip block so i need to do it on way that i send , unortunately this wont work becuase that is a global ip adress and they can not set a gateway for each 255 block for ex. i have 5 more ip 2 of them is on 78.159.xx.xx block so i need to set default gw to 217.20.117.1

So you're saying that your default gateway is an IP address that's part of a *different* network/subnet?
I don't know how this network has been designed, but typically I would expect that your default gateway would be something like
188.72.255.1
rather than 217.20.117.1 that you've mentioned earlier.
Take a look at mine for example:
[~]ifconfig eth0 Link encap:Ethernet HWaddr FE:FD:6D:4A:C1:69 inet addr:109.xx.xxx.105 Bcast:109.74.193.255 Mask:255.255.255.0 inet6 addr: fe80::fcfd:6dff:fe4a:c169/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:78742 errors:0 dropped:0 overruns:0 frame:0 TX packets:67114 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:35442733 (33.8 MiB) TX bytes:12607832 (12.0 MiB)
lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:8292 errors:0 dropped:0 overruns:0 frame:0 TX packets:8292 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1195297 (1.1 MiB) TX bytes:1195297 (1.1 MiB)
[~]netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 109.xx.xxx.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 0.0.0.0 109.xx.xxx.1 0.0.0.0 UG 0 0 0 eth0
So you can see my host has .105 assigned to eth0, and the default gateway is .1 of the same network/subnet.
You might want to check that your addressing is correct.

This is my two line on route-eth0 address0=217.20.117.1 subnet0=255.255.255.255 but what should be next line for default gateway the only thing that i
could
not complete is default gateway setting and my netstat table must looklike this : Destination Gateway Genmask Flags MSS Window

time restart manually with route add default gw

i have added eth0 address0=217.20.117.1 subnet0=255.255.255.255
the first command is ok but how could i set the second command to
cent
os to do it automatically
If you create a file named /etc/sysconfig/network-scripts/route-eth0
you
can put lines in it that will have 'ip route' added at the beginning and
executed
after the interface is up. "ip route" takes some different arguments than
the
"route" command - see "man ip" for details.

Why don't you post the results of 'ifconfig -a' and 'ip route show'? Giving information piecemeal is not helping anyone. _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
