supaya network lansung jalan secara otomatis
pada saat booting
13 ketik perintah di bawah ini
[root@localhost ~]# service network start
Sekarang coba reboot computer maka komfikurasi lan akan permanent
Langsung bias intrnet
===============================================================
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
Note
Agar claint bias brousing maka pastikan setingan di bawah ini sudah di set
* pastikan dns sudah di seklis masquerading all eth+ sudah di celis
masuk pada menu system >>pilih administration >> pilih ferewall >>setelah masuk pada menu tampilan firewall
pastikan dns sudah di seklis masquerading all eth+ sudah di celis
* selinuk tidak di aktipkan degan cara
[root@localhost ~]# vi /etc/selinux/config
===============================================================
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
===============================================================
* network manager sudah di disabled
bila clain tidak bisa brousing inter net maka buat iptables ketik di bawah ini
[root@localhost ~]# iptables -t nat -A POSTROUTING -s 192.168.0.0/255.255.255.0 -d 0/0 -j MASQUERADE
clain sekarang bisa brousing internet cihuuuuiiii
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
sudah di uji di lab network barliannet
perintah penting
[root@localhost barlianno]# /sbin/ifconfig –a
[root@localhost barlianno]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
[root@localhost barlianno]# vi /etc/sysconfig/network
[root@localhost barlianno]# vi /etc/resolv.conf
[root@localhost barlianno]# /etc/init.d/network restart
Mengaktipkan service network
[root@localhost ~]# service network start
Menon aktip
[root@localhost ~]# vi /etc/selinux/config
[root@localhost ~]# iptables -t nat -A POSTROUTING -s 192.168.0.0/255.255.255.0 -d 0/0 -j MASQUERADE
