If you do not use proxies for internet access then you don't need to do anything.

If you do use proxies for internet access you still shouldn't need to do anything. The climateprediction.net software should pick up your proxy settings from the settings in your browser.

So before reading any further, first try the software. The chances are you don't need to do anything at all.

The information below was relevant for older version of the climateprediction.net software. It is kept here to provide information in case your installation of climateprediction.net has problems accessing the internet because of proxies. The software has been tested on machines using recent version of Internet Explorer. We don't yet know whether the facility to pick up proxy settings will work if you have an alternative or old browser. We will update these pages as we gather further information.

Some organisations use proxies to control the flow of web traffic. These may be set up in a fairly complex fashion with different proxies for different types of internet communications, or they may be simple with only one proxy for all web traffic. If you do not use proxies then no action is needed. If you are not sure, try the climateprediction.net client and it will tell you if you need to look at this issue further, when it tries to connect to our servers.
 

If proxies are required, then they can be set up in one of 3 ways:
· Using Internet Explorer
· Using Netscape Navigator
· Using the climateprediction.net client

If you use proxies for your internet connection, it is likely that they will already be defined in either Internet Explorer or Netscape Navigator. The climateprediction.net client can pick up these settings. Unfortunately it can only pick them up if they are defined using a very particular format. Internet Explorer and Netscape Navigator are less "picky" about the format so even if you have proxies set in your browser you may need to either adjust the way they are defined or redefine them in the climateprediction.net client. In the future the client will be developed to remove this inconsistency.

So if you need to adjust your proxy settings here are the ways you can do it. Be sure to carefully follow the formats of the URLs indicated.

If you are using a LAN:

1. Click on Tools->Internet Options... in the menu bar
2. Click on the Connections tab
3. Click on the LAN Settings... button
4. Tick the Use a proxy server for your LAN tickbox
5. If the proxy should not be used for local addresses, then tick the Bypass proxy server for local addresses tickbox
6. If you will use the same proxy server for all protocols (http, https, ftp etc) then enter its address in the Address: textbox as http://proxyname

e.g http://protection
If the proxy is not on your local network, then you will need to give its full URL, e.g. http://protection.company.co.uk
You may also need to give the port to use on the proxy (most likely to be port 80), if so then enter the correct number for the port in the Port: textbox.
7. If you will use different proxies for different protocols (http, https, ftp etc) or only use a proxy for some protocols, then you need to
1. Click on the Advanced... button
2. For each protocol (HTTP, Secure (i.e. https), FTP etc) which needs a proxy enter the proxy's address in the Proxy address to use textbox corresponding to the appropriate protocol.  The format of the address should be <protocol>://<proxy_name>

e.g. http://protection or https://secure-protect or ftp://ftp-protect
If the proxy is not on your local network, then you will need to give its full URL, e.g. http://protection.company.co.uk
3. You may also need to give the port to use on the proxy, if so then enter the correct number for the port (most likely to be port 80 for http) in the corresponding Port textbox.
8. Enter any exceptions (IP addresses for which the proxy should not be used) in the text box labelled Do not use proxy server for addresses beginning with:
9. Click the OK button on each pop up form until you get back to Internet Explorer.

If you are using a modem:

1. Click on Tools->Internet Options... in the menu bar
2. Click on the Connections tab
3. In the Dial-up and Virtual Private Network settings textbox select the connection you want to set up proxies for
4. Click on the Settings... button
5. Tick the Use a proxy server for this connection tickbox
6. Follow the instructions from step 5 for "If you are using a LAN".

1. Click on Edit then Preferences... in the menu bar
2. In the Category: navigation bar, click on the + button next to Advanced so that it turns to -
3. In the Category: navigation bar, click on Proxies
4. Select Manual proxy configuration and then click on the View... button
5. For each protcol (HTTP, Secure (i.e. https), FTP etc) which needs a proxy enter the proxy's address in the Proxy address to use textbox corresponding to the appropriate protocol.  The format of the address should be <protocol>://<proxy_name>

e.g. http://protection or https://secure-protect or ftp://ftp-protect
If the proxy is not on your local network, then you will need to give its full URL, e.g. http://protection.company.co.uk
6. You may also need to give the port to use on the proxy, if so then enter the correct number for the port (most likely to be port 80 for http) in the corresponding Port textbox.
7. Enter any exceptions (IP addresses for which the proxy should not be used) in the text box labelled Do not use proxy server for addresses beginning with:
8. Click the OK button on each pop up form until you get back to Netscape Navigator.

If you do not have Internet Explorer or Netscape Navigator installed on your machine, or if you do not want to change your current settings in these applications, then you can set up the proxies to use in the climateprediction.net client itself.
When you first start-up the climateprediction.net client, the registration form appears.
Click on the Proxy Server Configuration button at the bottom of this form.
In the Address: textbox on the Proxy Settings form which then appears, enter the correct proxy string.  The proxy string should be formatted as follows:

• If you use the same proxy for all connections (http, https, ftp etc) then enter its URL, e.g. http://protection
• If the proxy server is not on your local network, then you will need to include the full address of the proxy server, e.g. http://protection.proxy.co.uk
• If you have different proxy settings for http and https connections, then you need to specify which proxy should be used for which protocol.  This can be done by putting the protocol type (e.g. http or https) in front of the proxy URL followed by an equals sign.
• e.g. http=http://protection

to specify that the client should use the proxy http://protection for http connections, but should use no proxy for https connections.
• e.g. https=http://protection

to specify that the client should use the proxy http://protection for https connections, but should use no proxy for http connections.
• e.g http=http://protection https=http://secure-prot

(note the space between the two proxy settings)
to specify that the client should use the proxy http://protection for http connections and the proxy http://secure-prot for https connections.
• When you have entered the correct proxy settings for your internet connection, click on the OK button on the Proxy Settings form.
• Complete your details on the Registration form and press Register.

If your registration fails, for whatever reason, and you close the registration form, your proxy settings will be lost and you will have to re-enter them when you next try to register your client.
If your registration succeeds then the client will store your proxy settings in its status files and you will not need to enter them again.
You can change your proxy settings at any time by selecting the Internet Settings menu option on the client, and the Change Proxy Settings submenu item.  This will bring up the Proxy Settings form, which you can use as detailed above.
