Bu yazıda bir örnekle Linux altında nasıl GRE tünel oluşturacağımızı anlatmaya çalışacağım.
Birbirine Internet üzerinden erişebilen iki Linux cihaz düşünelim. (IP adresleri yine de Internet üzerinde kullanılmayan bloktan verilmiştir)
IP TANIMLARI
node1 (eth0 internet, eth1 iç ağa bakan kısım olsun)
eth0 : 192.168.200.150/24
eth1: 10.1.1.1/24
tunel arayuzu (tonode2): 172.16.151.1/30
node2 (eth0 internet, eth1 iç ağa bakan kısım olsun)
eth0: 10.10.10.150/24
eth1: 10.2.1.1/24
tunnel arayuzu (tonode1): [...]
VNC server configuration is pretty straight forward in redhat. Here are the steps that you should complete in order to run a functional VNC server in a few minutes.
Our test user is : mert
1) Adjust /etc/sysconfig/vncservers config file as below:
VNCSERVERS=”2:mert”
2) Login to mert account and set vncpassword
[root@rh54-3 sysconfig]# su – mert
[mert@rh54-3 ~]$ vncpasswd
Password:
Verify:
[mert@rh54-3 ~]$
3) Start [...]
As network cards or links may fail, we may solve this problem by creating multiple links to our network devices. One way is interface bonding which we will configure one in our example. I assume that your linux have three interfaces eth0,eth1 and eth2. We will use two of the interfaces;
Slave Interfaces : eth1 and [...]
I was trying to find out how I can add a permanent route into Redhat so that after the reboot routes should persist. I have found the way but I must say that I really didn’t like it:( I liked the way Gentoo does it or Slackware but Redhat’s way seems to be too simplistic [...]
