How to remove caps/num lock notifications




Every time when I press Caps Lock or Num Lock on keyboard notification balloon pop-up in right low corner of the screen that it’s been turned on/off. It is annoying and it’s disabled me from typing for a couple of seconds. So I decided to turned off, process responsible for notification is QLC Controller.

You can turn off from Task Manager, but every time you Log Off or Turn Off your computer it’s started again. The best way is to turner of from Startup. To do so, start MSCONFIG from Run and from Startup tab and uncheck HP Hotkey Support. 



This will solve problem permanently.

How To Configure NTP on Cisco router - GNS3



Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks and it works on Application Layer. The protocol uses the User Datagram Protocol (UDP) on port number 123.
I will configure router R1 to use NTP clock synchronization from 2.rs.pool.ntp.org, the source of server from http://www.pool.ntp.org/ which is the largest virtual cluster of time servers.
So let's start.
First check time and date on R1...

R1#show clock
*00:14:33.191 UTC Fri Mar 1 2002

Before we configure R1 to use NTP first of all we need to configure name server and lookup for domain name.

R1(config)#ip domain-lookup
R1(config)#ip name-server 4.2.2.2
