This is only really necessary in the case you don't want DHCP. If you are dealing with an encrypted LUKS server on the internet, you will often want to have a static IP so you know which IP to connect to (or if you have a semi-static IP assigned by DHCP).
SET IP Address by /etc/initramfs-tools/initramfs.conf
Subnet Mask: 255.255.255.0
Getting started, let's enable ephones and DNs we can add a phone with a telephone number:
!this enables ephone registration otherwise phones cannot register
!max-ephones 2 says we can have a maximum of 2 phones, change to your needs (or to the limit set by your IOS image)
In most of the Cisco router IOS I find the ports like ge0/0 ge0/1 and ge0/2 or whatever your ports are down. They will not even give you a link light. So one of the first tasks should be getting the port you are working with up.
In my case the first goal is often connectivity with the LAN and WAN.
LAN = your local area network (eg. in the office/home )
WAN= your ISP/public internet (eg. fiber/cable/dsl/ethernet).
In these examples I as........

This is important because if your console doesn't look like below none of the commands will work!

This is useful for security purposes especially on a server which may have a public IP assigned to it but has a second NIC for the LAN.
Here is how you edit smb.conf:
interfaces = 192.168.1.50
bind interfaces only = yes
As you can see above it will only listen on 192.168.1.50 and remind to keep the "bind interfaces only"option.........
At first my BIOS said the card may not work right because there is no more option ROM space.
I disabled the Option ROM for both LSI 1068 and 2008 chipsets, Network Boot ROM and most other PCI slots, Serial Port, etc... and the message went away but the card still does not work properly.
But it still cannot initialize the card properly(does not work):

Basically you should always be 100% sure that whatever IPyour mail server sends out with has reverse DNS/PTR records. Remember that unless you own your IPs then you won't be able to set your own reverse DNS. Even if you were to create a reverse PTR record on your DNS servers it will be ignored. Reverse DNS is queried to pre-assigned DNS servers of your ISP, so therefore you'll need to contact your ISP/Colo/Hosting provider to do a reverse DNS entry.
If you don't have........
