what is virtual private network & proxy server?

If a site is banned in some organization, we surf that banned site through a proxy server. So what is happening inside?

I know proxy servers maintain logs, so they are not secure.

Virtual private connection is better than proxy server because they do not maintain logs.

I want to understand the basics of both the things: VPN & proxy server.

Can anyone please answer these in simple language..

Re: what is virtual private network & proxy server?

I have'n used VPN but i have built & sold many proxy servers. They keep logs indeed but only if you get one who keeps... On SourceForge is a project called Mocks and is currently version 0.0.2

You can configure it easy.

Code:

PORT                         = 10080       # Port MOCKS is to listen to

MOCKS_ADDR              = 0.0.0.0     # IP adress MOCKS is to bind to

LOG_FILE                 = mocks.log   # MOCKS log file  (Guess you can remove that)

PID_FILE                 = mocks.pid   # File holding MOCKS's process ID

BUFFER_SIZE                 = 65536       # Traffic buffer size in bytes

BACKLOG                     = 5           # Backlog for listen()

NEGOTIATION_TIMEOUT         = 5           

CONNECTION_IDLE_TIMEOUT = 300

BIND_TIMEOUT                = 30

SHUTDOWN_TIMEOUT        = 3

MAX_CONNECTIONS                = 50  (This is the max number of connections YOU CAN MAKE)

Then on Linux/FreeBSD/SunOS just use ./build and you will have your own socks5 server configured.
To start it just

Code:

./mocks start - start socks server 

./mocks shutdown - to stop it

./mocks help - to see some things i just write in here :)

I think that there is a -f argument to force socks server to start.
