[CLUG] Proxies configuration?

[Marcus Viertel]

First to reply to your question about the proxy:

A proxy server is basically an Internet Gateway, used by companies or people
for the following reasons:

1) They have only one public IP address and need to provide access for a
number of people (and don't have a router capable of network address
translation)

2) They have a low speed internet connection and want to speed things up by
utilising local cache for ftp and http

3) They want to use some level of usage monitoring on web and ftp usage.

A proxy server will take a connection from an internal user and terminate it
on behalf of the server that the user is trying to connect to. Then the
proxy will attempt a connection to the actual server on behalf of the user.
If the connection is established, the user can access the site as usual, but
with a few differences:
1) Any items (e.g. graphics) that are loaded more than once via this
connection, will be served from the proxies cache rather than requested via
the internet. This helps to speed up the connection somewhat.
2) The IP address of the user is hidden to the outside world, which does
provide SOME level of security.
3) The connection activity is logged, and can be analysed later

When setting up proxy servers, it is important to know which ports need to
be used. I know of servers using ports 82, 8000 and 8080. Also the ftp
support varies, from real ftp proxies, to transparent http proxies that
support passive ftp connections.

Bottom line for your installation:
If you want to use your ISP's proxy server, look it up in the settings and
use that. However it is logical to use a server that is as close to you as
possible, otherwise the acceleration goes out the window.

Cheers,

Marcus

Hi one and all,
once again I need some help with setting up linux. I am trying to setup
Mandrake 8.1 and it is asking for Proxie HTTP and FTP, in the past I have
just typed "linuxbox.com" But I would like to know what they are for and
what I should put in there.
I have been playing with Mandrake Linux for a few weeks and I was very
pleased when I managed to get a shared folder to work over my windoze
network :-) But for some reason I am un able to SEE the win98 box (or
anything for that matter) from the linux box. Where am I going wrong?
All help will be greatfully recived.

God Bless,
Kevin B:-)

Life has many choices, Eternity has two. What's yours?
