Information needed:
- Assigned IP address.
- Assigned Subnet Mask address (255.255.255.0).
- Assigned Gateway address (Change the last octet of the IP address to "1").
- Assigned DNS (202.78.97.2).
Log in as root, or switch to the root user by typing su root.
At your shell prompt, type the following:
/sbin/ifconfig eth0 netmask 255.255.255.0 x.x.x.x
Replace x.x.x.x with the Static IP address assigned to the client.
Once the command has executed, type /sbin/ifconfig. The results should look similar to:
lo Link encap:Local Loopback
inet addr:127.0.0.1 Bcast:127.255.255.255 Mask:255.0.0.0
UP BROADCAST LOOPBACK RUNNING MTU:3584 Metric:1
RX packets:1775 errors:0 dropped:0 overruns:0
TX packets:1623 errors:0 dropped:0 overruns:0
eth0 Link encap:Ethernet HWaddr 00:3E:11:61:FF:5E
inet addr:xxx.xxx.xxx.xxx Bcast:xxx.xxx.xxx.xxx Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:4325 errors:0 dropped:0 overruns:0
TX packets:3257 errors:0 dropped:0 overruns:0
Interrupt:11 Base address:0x280
Open the file /etc/sysconfig/network in your favorite text editor. The contents should look similar to:
NETWORKING=yes
FORWARD_IPV4=false
HOSTNAME=anyname
GATEWAY=xxx.xxx.xxx.1
GATEWAYDEV=eth0
Enter the default gateway IP address of the client (xxx.xxx.xxx.1).
Save the file.
On the file /etc/resolv.conf in your favorite text editor. The contents need to look like the following:
nameserver 202.78.97.2
nameserver 202.78.97.3
Save this file.
It should now be connected via DSL. To verify connectivity, ping the gateway
It should get he following response:
PING xxx.xxx.xxx.1 (xxx.xxx.xxx.1): 56 data bytes
64 bytes from xxx.xxx.xxx.1: icmp_seq=0 ttl=254 time=11.935 ms
64 bytes from xxx.xxx.xxx.1: icmp_seq=1 ttl=254 time=12.968 ms
64 bytes from xxx.xxx.xxx.1: icmp_seq=2 ttl=254 time=12.824 ms
64 bytes from xxx.xxx.xxx.1: icmp_seq=3 ttl=254 time=10.028 ms
64 bytes from xxx.xxx.xxx.1: icmp_seq=4 ttl=254 time=12.744 ms
--- xxx.xxx.xxx.xxx ping statistics ---
5 packets transmitted, 5 packets received, 0% packet loss
Press CTRL-C to stop pinging the server.
Your Linux box should now be connecting via your DSL line.
NOTE: To make these changes permanent between reboots, you must put the command
/sbin/ifconfig eth0 netmask 255.255.255.0 xxx.xxx.xxx.xxx in /etc/rc.local.
RedHat machines may use the /usr/sbin/netconfig utility instead.
