TCP Configuration & DHCP Server;
It is
addressing of a computer in order to communicate with other computers.

2 values ​​must be entered.

1.) ip address (computer’s digital address)
2.) subnet mask (the value used to calculate which network group the computer belongs to)

2 values ​​are optional.

1.) gateway (the ip that enables the computer to communicate with external networks)
2.) dns (the address used to find the ip equivalents of domain names)

approximately 200 address systems other than this
varies according to operating system and software.

——————————–

tcp configuration can be configured in 2 ways.
1.) manual
2.) automatic
There is a server/client system that allows tcp configuration to be configured in a special way for each computer.

dhcp server
dh client   ->  each

DHCP (dynamic host control protocol l)
————————————
used to distribute tcp config.

The process is done in 5 steps.
1.)  DHCP Discovery
client sends broadcast message to 0.0.0.0/32 (udp message)
2.)  Server receiving DHCP Offer
makes an offer to client a.
3.)  DHCP Request
4.)  DHCP Response
5.)  DHCP Acknowledge
client sends information to the server that it has received the ip.

Dhcp Configuration :

configuration is done via /etc/dhcpd.conf file.

This file is not available on servers. but when the file is created
dhcp server can be run.

To install dhcp :
yum install dhcp*

after installation
when you want to run the service
* service dhcpd start
command gives error. (note: no dhcpd.conf file)

firstly, copy the sample file under /etc.
Sample File: /usr/share/doc/dhcp-4.0.0/dhcpd.conf.sample

cp /usr/share/doc/dhcp-4.0.0/dhcpd.conf.sample /etc/dhcpd.conf

File Editing :
/etc/dhcpd. Open the conf file…..
