Membuat Router menjadi DHCP

Perintah dasarnya cukup simple

Router(config)#int fa 0/0
Router(config-if)#ip address 192.168.1.1 255.255.255.0
Router(config-if)#no shutdown

Router(config-if)#ip dhcp pool A
Router(dhcp-config)#default-router 192.168.1.1
Router(dhcp-config)#network 192.168.1.1 255.255.255.0
Router(dhcp-config)#end
Router#write

Memberikan akses VLAN secara Range

Misal kita mau memberikan akses VLAN antara Port 10 – Port 20,

cukup dengan command

# interface range fa 0/10 – fa 0/20

# switchport acc vlan….

 

 

Dasar konfigurasi command Router

Menggabungkan column di excel

Salah satu rumus yang sering digunakan dalam excel yaitu “CONCATENATE”

Fungsi CONCATENATE sebenarnya menggabungkan content column dalam excel.

Kita langsung Praktek saja agar lebih paham,

concatenate

 

di tabel colum A, B, C terdapata Kata Rak, Buku, Meja

dan kita mau semua kata di colum tersebut digabung, caranya adalah menggunakan Rumus CONCATENATE =CONCATENATE(A1,” “,B1,” “,C1) Tanda ” ” digunakan untuk spasi antar kalimat.

Cara melacak Hanphone Hilang

Sebenarnya tips ini hanya berlaku dengan dua kondisi :

=> yang pertama Handphone dalam keadaan hidup

=> yang kedua Hanphone dalam keadaan On internetnya

=> yang ketiga Handphone masih menyimpan Account gmail kita, akan tetapi bila handphone sudah di reset default maka tips ini tidak berlaku.

Buka web : https://www.google.com/android/devicemanager

dalam aplikasi ini juga kita bisa call dengan RING dan mencari Lokasi handphone dengan GPS.

 

Backup Driver

Salah satu Tools yang saya kira wajib harus punya adalah backup Driver Genius. Salah satu fungsi software ini adalah membackup semua driver yang sudah terinstall di komputer , baik itu driver Printer, VGA, LAN, dan yang lainnya.

Sehingga jika sobat suatu saat install ulang Operating system tidak usah repot-repot untuk install satu persatu drivernya.

langsung backup dan recovery langsung selesai..

Untuk download silakan di cari di Mbah Google yang bajakan dan legal juga ada 🙂
