mengenai contents


File ini menyimpan package yang kita install di solaris, jika kita hendak membuat mesin cloning yang memiliki package level sama, maka bisa melakukan copy file ini ke mesin baru tersebut. Dengan asumsi mesin baru ini akan dibuat sama level packagenya dengan mesin reference.

Untuk melakukan test terhadap file contents ini bisa dilakukan dengan mereboot(shutdown -i6 -g0 -y), jika server berhasil up berarti contents nya lengkap.

Dapat command baru screen

Pastikan screen terinstall di sun solaris/linux anda:
#which screen

Setelah itu tinggal ketik:
lakukan aktifitas anda, jika anda ingin keluar :
ctrl + a and z

Lalu jika anda ingin kembali bekerja:

login ke mesin anda dan ketik

#screen -r

maka anda masih mendapatkan sesi anda tanpa terinterupt.
