freenet6-6.0.1-1.src.rpm (528)Step 3:
Compile source rpm and install

Copy konfigurasi eth yg sudah ada
# cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth0.9
edit ifcfg-eth0 menjadi seperti ini
DEVICE=eth0 ONBOOT=yes BOOTPROTO=none
edit ifcfg-eth0.9 menjadi seperti ini (sesuaikan dengan ip/network/netmask milik anda)
DEVICE=eth0.9 BOOTPROTO=static BROADCAST=192.168.200.255 HWADDR=00:0C:29:21:E0:2E IPADDR=192.168.200.101 NETMASK=255.255.255.0 NETWORK=192.168.200.0 TYPE=Ethernet ONBOOT=yes VLAN=yes
