contact lens - some info

Started trying contact lens instead of spectacles

something which i wish to share.
1. there is chance that you may put the contact lens in reverse direction. - during that you will be able to see , but you will be irritated to have the contact lens , Remove the lens, Just make it correct direction and put the lens back. => Now everything should be set.
(OR in other words)
Whenever you are irritated to have lens in your eyes , it is most likely that you put your lens in wrong direction. thats the point :) , reverse it and wear it again , you are set.

2. first week wearing contact lens was bit awkward. I got so much pain sometimes in the eyes.
Slowly you will understand the nuances of wearing lens.
Watch youtube videos for understanding how to wear lens.

One idea which I follow is i comfortably sit in front of Large mirror, put the lens by looking at the mirror and then just start looking at the ceiling of your room closing the eyes immediately after putting the lens.
I mean you need to tilt your head from mirror view position to ceiling view position.
Everything will be set.

TFTP server returns "Error Code 0: Permission Denied"

TFTP server returns "Error Code 0: Permission Denied"

if you get this error, make sure the tftp folder access permission.

change it to chmod 777 /var/lib/tftpboot.

[EDIT]: So you are changing the permission of tftpboot folder such that anybody can access it. Beware of it!! 

The above is bit dangerous to play with, better way is :

chgrp -R tftpd /var/lib/tftpboot

Adjust the permission as per your need.
