my first lesson in network

pelajaran pertama yang saya dapat di dunia kerja adalah mempelajari mikrotik;

1. set interface LAN CARD bila ada 2

interface >> set ether1 name=internet

>> set ether2 name=lokal

2. set ip address

ip address >>  add address = xx.xx.xx.xx/xx interface = internet

>> add address = xx.xx.xx.xx/xx interface = lokal

3. set ip route

ip route

ip route >> add gateway = xx.xx.xx.xx

4. ip firewall nat

ip firewall nat >> add chain=srcnat out-interface=internet src-address=192.168.0.0/24 action=src-nat to-addresses=202.133.81.243 \

5.  Ip service

/ ip dns
set primary-dns=202.133.81.3 secondary-dns=202.133.81.9 allow-remote-requests=yes cache-size=2048KiB cache-max-ttl=1w

Contoh mengubah filesistem ke ext3

untuk mengubah filesistem ext3 ke reserifs yaitu:

1.) umount dulu partisi file ext 3 di hard drive
2.) pastikan rpm -qa|grep reiserfs-utils sdh terinstall
3.) setelah itu mkreserifs -f /dev/sda1 (contoh)
4.) mount file sistem yg sdh diubah ke reserifs dg mount /dev/sda1 /cache1
5.) kemudian ubah di /etc/fstb menjadi:

/dev/sda1               /cache1                reiserfs defaults,noexec,noatime,notail       1 2
