> Before starting the Squid server we need  to create a password file by using NCSA for that we need
apache2-utils  (ubuntu)

> for the first time creating the passwd we need to use -c option for htpasswd command , for next don't use -c

$ /usr/bin/htpasswd -c /etc/squid3/passwd  somexyz
New password:
Re-type new password:
Adding password for user somexyz

>Now start squid server :

$ service squid3 start

>  Squid proxy will  start but we not able log in, because the password file storing in the format md5, but Squid 3 uses Crypt format password.

> To uses Crypt format password user we need to use  "-d" for more details "/usr/bin/htpasswd --help"

$ /usr/bin/htpasswd -d /etc/squid3/passwd somexyz1

New password:
Re-type new password:
Adding password for user somexyz

> Now restart the Squid service

$ service squid3 stop
$ service squid3 start

> Now we can login with somexyz1 user account into squid proxy : - )
