GNS3 is one of the network simulation software very useful and powerful, many network devices can be simulated, here's how to install Cisco ASA. My Practice using GNS3 1.3.3, ASA 8.4 1. Download the cisco asa source files  asa842-k8.bin   and  asa842-vmlinuz 2. Extract them and place them in the GNS3 images directory. 3. For example : C:\Users\<user name>\GNS3\images\QEMU\ 4. Go to Edit -> Preference -> QEMU -> QEMU VMs 5. Click New -> Give Name -> Set typenetwork devices can be simulated, here's how to install cisco asa

Essential Vi Commands Open a file: #vi filename To go into edit mode: #press ESC and type I To go into command mode: #press ESC To save a file : #press ESC and type :w fileName To save a file and quit : #press ESC and type :w

My practice using tinycorelinux, it's usually used in GNS3 and usually used to test network connectivity, because it's lightweight. Add an IPv6 address There are two ways : 1. Using "ip" Usage: # /sbin/ip -6 addr add <ipv6address>/<prefixlength> dev <interface>  Example: # /sbin/ip -6 addr add 2001:0db8:0:f101::1/64 dev eth0  2. Using "ifconfig" Usage: # /sbin/ifconfig <interface> inet6 add <ipv6address>/<prefixlength> Example: # /sbin/ifconfig eth0 inet6 add 2001:0db8:0:f101::1/64 Show IP Address # /sbin/ifconfig eth0 or # /sbin/ip -6 addr show dev eth0

Kalau linux yang kita install mode CLI, berikut adalah cara mount, eject & safely remove flashdisk di linux : 1. Tancapkan flashdisk/pendrive 2. #fdisk -l (untuk memeriksa letak/nama device flashdisk tersebut) 3. #mkdir /media/flashdisk  (membuat folder tempat mount flashdisk) 3. #mount /dev/sdb1 / media/flashdisk (mount flashdisk ke media/flashdisk dan sdb1 adalah nama/letak devicenya). 4. #cd /media/flashdisk (masuk dalam media flashdisk) 5. #ls (melihat isi flashdisk, disini sudah bisa mengakses isi flashdisk)
