COMPUTER KNOWLADGE & BEST TRICK

Backup Upgrade and Transfer

1. Backup CCProxy

Advantage of backing up CCProxy: When CCProxy goes wrong, data could be restored.

1) The settings of CCProxy itself is saved in "CCProxy.ini".

2) Accounts information, filter rules and time schedule are all saved in "AccInfo.ini". You just need to back-up these two files.

3) If you modified files in Web directory, then this directory also needs backing-up.

4) If you want to save the old logs, back-up log directory as well.

2. Upgrade CCProxy

Before upgrade, it is recommended that you should back-up files first.

1) In setting up directory, double-click "unins000" to uninstall CCProxy older version (after uninstalling CCProxy, none configuration files would be delete) (Figure 1-1).

Figure1‑1

2) Set up the new version. Please note that the new version should be saved into the old setting up directory. Only in this way, the old configurations and account information can be imported to the new version.

3. Transfer CCProxy

Before upgrading, it is recommended that you should back-up files first.

1) Uninstall CCProxy.

2) Copy CCProxy directory and paste it to the new server.

3) On the new server, install CCProxy in the CCProxy directory.

CCProxy Upgrading Steps

Before upgrading, it is recommended that you should back-up files first. Configurations of servers are all saved in "CCProxy.ini", while accounts information, filter rules and time schedule are all saved in "AccInfo.ini". You just need to back-up these two files.

If you modified files in Web directory, then this directory also needs backing-up. If you want to save the old logs, back-up log directory as well.

Upgrading steps are as follows:

1) Backing-up the files you need.

2) In setting up directory, double-click "unins000" to uninstall CCProxy older version (after uninstalling CCProxy, none configuration files would be delete) (Figure 1-1).

Figure 1‑1

3) Set up the new version. Please note that the new version should be saved into the old setting up directory. Only in this way, the old configurations and account information can be imported to the new version.

Configuration of Dual-NICs

There are many kinds of network topology environment of surfing the Internet via proxy. Here introduces how to configure dual-NICs:

1. Configuration of NICs

1) There are two network cards on the proxy server, and the one connected to the Internet is called External NIC. The external NIC could be configured accordingly, as long as the server could access the Internet normally.

2) The one that connects the Switch and the terminal is called Internal NIC.

While configuring the internal NIC, please note that the IPs of the internal NIC and the external NIC should not be in the same IP range. Besides, gateway and DNS could be left unconfigured.

2. Configuration of Clients

In the "Local Area Connections" dialogue box, please configure as follows:

1) IP address (the IP address of clients should be in the same IP range with the IP address of the internal NIC of the server).

2) Subnet mask (255.255.255.0).

3) Default gateway.

4) DNS address (DNS is the IP address of the internal NIC of the server).

Installation of CCProxy

Step 1 - LAN networks configuration

Normally, the clients and server are connected with A Hub, Wireless Hub, Switch or Router. The network protocol between the server and clients is TCP/IP. Therefore both the server and the clients have an IP address. The server IP address is static and fixed. The clients IP address can be fixed or dynamic which is obtained through DHCP. CCProxy only requires that the clients can ping through the server IP address. We know that the server may have multiple IP addresses, but must have one that is used to connect with other LAN clients. The IP address that is used to connect with the other LAN client is called the proxy server address. We generally assumed this to be 192.168.0.1.

If the clients and server have not yet been setup to have a connection, we recommend allocate IP addresses like this at below:

	IP address	mask	gateway	DNS
Server	192.168.0.1	255.255.255.0	empty	empty
Client1	192.168.0.2	255.255.255.0	192.168.0.1	192.168.0.1
Client2	192.168.0.3	255.255.255.0	192.168.0.1	192.168.0.1
...	...	...	...	...
Client99	192.168.0.100	255.255.255.0	192.168.0.1	192.168.0.1

How to detect whether ping Requests are transferring through between the clients and server? At the client, in the "start" menu -> "run" -> "cmd", assuming that the server IP is 192.168.0.1, in the command line, to type "ping 192.168.0.1" then press return. If the result is similar to that at below, it means the client is connected to the server successfully.

Pinging 192.168.0.1 with 32 bytes of data:

Reply from 192.168.0.1: bytes=32 time=2ms TTL=150

Reply from 192.168.0.1: bytes=32 time=7ms TTL=150

Ping statistics for 192.168.0.1:

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:

Minimum = 2ms, Maximum = 7ms, Average = 4ms

If the result is like that at below, it means the client cannot connect to the server.

Pinging 192.168.0.1 with 32 bytes of data:

Request timed out.

Ping statistics for 192.168.0.1:

Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

If the client cannot connect to the server, you need to check the IP address settings and the connections to the Hub, Switch or Router on the clients and server.

Step 2 - Internet connection configuration

We know that there are many ways of connecting to the Internet, which are for example, ADSL, optical fiber, satellite, broadband etc. CCProxy is not concerned about the manner in which the Internet connection is established, as long as the server is successful connected to the Internet.

The simplest way to check the server can access the Internet is to input a web site address into the browser and see if the machine is able to access the web pages.

Users frequently mentioned single and dual NIC. In fact, the CCProxy is not concerned with hardware equipment. Both single and multi-NIC cards are supported and there are no special settings.

Special mention is that if the clients have been able to share the Internet, such as through the router, and hope to use the CCProxy to manage and control the clients' Internet access. You might need to do some changes on your hardware.

For example:

(Figure 1)

In this case, the clients can access the Internet directly with the Routers bypass proxy server. That's to say, CCProxy cannot control the clients. We need to isolate the client from Internet and force clients to access the Internet via the proxy server.

We have two methods to realize this.

Method 1:

Add one NIC card on the server and change the LAN networks as:

(Figure 2)

Method 2:

Configure the NAT or route settings in the router and block all LAN IP address accessing the Internet directly except the server IP address. Only some advanced routers have this function. Please do this with the router's administrator.

Step 3 - Install CCProxy on the Server

Suppose the server IP address in the LAN is 192.168.0.1, and then 192.168.0.1 is the proxy server address.
You can download CCProxy here. Run ccproxysetup.exe and follow the on-screen instructions to install CCProxy.
Run CCProxy on the server (Figure 3).

(Figure 3)

If you want to know more about server configurations, please read "Server Configuration".

If you get problem in launch CCProxy, please refer to "CCProxy Start Problem".

Step 4 - Add client's IP into CCProxy

Choose one computer in the LAN that needs to access the Internet. Suppose the IP address of the computer is 192.168.0.2.
Open CCProxy main window, click "Account" button, then popup "Account Manager" dialog box.
Select "Permit Only" in "Permit Category" and select "IP Address" in "Auth Type" (Figure 4).

Make Proxy Server Settings for IE, Firefox, Chrome, MSN, Yahoo, Skype, CuteFTP

A proxy server acts as a security barrier between your internal network and the Internet, preventing others on the Internet from being able to obtain access to information that is located on your PC or other computers in the LAN. Besides security considerations, people use a proxy server also for some other purpose such as to implementInternet connection sharing, to apply Internet access control for LAN users who want to connect to Internet, toaccess blocked websites like Orkut, Myspace, Youtube, Facebook and so on.

To apply the above features of a proxy server, you need to make proxy server settings on the client computers first of all. Suppose the proxy server address is "192.168.1.100", bellow are how to make proxy server settings for various network applications step by step.

Proxy server settings for IE

Click "Tools" -> "Internet Options" -> "Connections" -> "LAN Settings" -> select "Use a proxy server for your LAN" -> "Advanced", configure as bellow.
