Setup Syslog server

setup Syslog Server lab with GNS3:
=============
Syslog Server to catch the device information relating to log information. Example if a Router generate a log about UP/UP interface. This log message will send over to the Syslog server.
Step 1: Download and install Syslog server

or Download a full blown PRTG system monitor: Syslog server and SNMP server.
If you download PRTG, read how to enable Syslog trap and SNMP trap:

---

Step 2:
copy below code into the router

---

!You’ll need a NTP server- a remote clock server
!or you can setup the clock locally like below manually
clock set 7:00:00 14 June 2022

conf t
service sequence-numbers
service timestamps log
!
!We want to sent log info about loopback0 interface.
interface loopback0
ip address 192.168.2.9 255.255.255.255
no shutdown
!
!logging Server
logging on
logging host 192.168.1.8
!Type of message log is set to information
logging trap info
!

loggin origin-id hostname
logging facility local6
!default UDP port, don’t forget to open that port on Window Firewall.
logging host 192.168.1.8 transport udp port 514
!Interface to monitor
logging source-interface lo0

---

Step 3:
on the router, you can try to shutdown ON/OFF the above interface, to see the log will send over to the Syslog server you setup and install in step 1.

——
You will see message like this: 
R2(config-if)#no shut
000175: 03:01:49: %SYS-6-LOGGINGHOST_STARTSTOP: Logging to host 192.168.1.8 port 514 started – reconnection

---

If you get an error message in PRTG system monitor like 162 is in used by another process
Find out what program is using that port number: 162
cmd > netstat -ano|find “:162“
-Then use TaskManger to kill that process, it should work after.

Below is the show Run code for Both: SNMP server and Syslog Server:
