Does JAP work with every internet provider?
You can use JAP with any ISP. Windows users should be aware of the exception with AOL and T-Online. If your provider requires a certain proxy, please read the instructions for required proxies.
Does JAP work with low-cost dialers (for example oleco)?
A low-cost dialer automatically chooses which internet provider is used based on the lowest price offered at that time of day.
If you use Internet Explorer as your browser, it takes on the proxy settings required for connecting to this provider. If there are none, which is usually the case when a low-cost dialer is used, the proxy settings in Internet Explorer remain empty. Therefore, JAP will not work.
One solution is to use a browser other than Internet Explorer.
Does JAP work with DSL?
Yes! But please note that surfing with JAP will result in a slower connection speed than you would otherwise achieve with DSL. (Why?) Modem or ISDN users shouldn't have any noticeable speed disadvantage.
If you use Internet Explorer as your web browser with DSL, you'll need to configure the proxy settings under "LAN Settings". (Instructions)
Does JAP work with the company network?
Yes, as long as access to JAP isn't blocked at your workplace. If your workplace requires a certain proxy, be sure to see the tips for proxies.
I have a personal firewall (for example ZoneAlarm or Norton)? What should I be aware of?
JAP works with a personal firewall. We also recommend the use of one, since JAP only helps you surf anonymously and cannot protect your computer from external attacks. (Why?)
When a new program is started for the first time, most firewalls ask whether the program should receive the privileges it asks for. You should simply answer this question with yes and also say that this setting should be saved for all future cases for this program (if possible). Otherwise you'll be asked again with each start of JAP.
Please note that your firewall will not necessarily directly say that JAP wants internet access. Instead it may say that one of the following programs is being asked for: java, javaw, jview, wjview, jre or jrew. These are the names of the Java interpreter, depending on version and distributer.
JAP requires the following rights, which you need to configure by hand if the firewall doesn't ask for them or if despite the firewall asking for them, it doesn't work:
- JAP needs to be Server. This is necessary so that the web browser can send its requests to JAP. JAP only accepts requests from the local computer unless you configure it otherwise. If you want to be completely certain, configure your firewall, too, so that JAP can only be accessed from the local computer.
- JAP needs a connection to the internet (to the mixes and infoservice). Otherwise you can't surf. For this purpose, JAP connects over ports 6543 (infoservice), 7544, and 6544 (first mix of the mix cascade), depending on which mix cascade is used. These ports might need to be enabled manually.
- In principle, you could confine the allowed access for JAP even further: the infoservice runs at "infoservice.inf.tu-dresden.de" and the first mix of the Dresden-Dresden cascade is at "mix.inf.tu-dresden.de". Your computer only really needs access to the appropriate ports for these two servers. Otherwise, you only need access to your name server in order to resolve the above mentioned addresses.
If you don't find a way to enable these ports, JAP can use other ports, but only with the Dresden-Dresden cascade. To do so, carry out the following steps:
- In JAP under "Config/InfoService", change the port from 6543 to 80
- Go to the "Config/Anonymity" page. Click on the "Fetch" button and choose the "Dresden-Dresden" cascade from the drop down menu.
- Select the "Manual Configuration" radio button and change the Anon-Port from 6544 to 443.
- Try to activate the anonymous web access.
I'm forced to use a certain proxy. What do I have to configure?
Some internet service providers set a specific proxy in the web browser, but this is often not necessary. First you should test to see if you can access the internet without this proxy.
Carry out the following steps only if you're sure that you have to use a specific proxy. This is usually the case if you access the internet over a local network (for example at work).
- Determine the internet address and port of the required proxy. This can usually be found in the proxy settings of your web browser.
- In JAP, Activate the checkbox under "Config/Proxy-Firewall" and enter the address of the required proxy. Some proxies require a user authorization. If this is the case, activate the appropriate checkbox and enter the User ID (usually your login). (You should first try it without authorization and only do this step if it doesn't work.)
- Under "Config/InfoService", change the port number from 6543 to "80".
- Go to the "Config/Anonymity" page. Click on the "Fetch" button and choose the "Dresden-Dresden" cascade from the drop down menu.
JAP should work after these steps, but you will only be able to use the Dresden-Dresden cascade from behind a firewall or required proxy (so far).
If you are able to activate and use the JAP service but after a certain amount of time are unable to continue surfing, that means the forced proxy automatically closes connections that are unused for a period of time. In this case (and please, only then), go to "Config/Miscellaneous" and activate the checkbox "Send dummy packet every x seconds". JAP will then send data in regular intervals so that the proxy doesn't close the connection.
I have a DSL or ISDN router. What do I need to configure?
As opposed to modem or ISDN users, you need to configure the proxy settings in Internet Explorer under "LAN Settings" if you use a router. (Instructions)
I use KEN! DSL or a similar local proxy solution. What do I have to configure?
By using a KEN! DSL proxy, all of your internet page requests are sent through this proxy. Thus KEN! DSL works as a local forced proxy and you'll need to follow our forced proxy instructions for configuring JAP. Nevertheless, we can't guarantee that it will work.
Furthermore, the automatic disconnect feature is problematic for your anonymity. (Why?)
I use Fritz!Web. Can I also use JAP?
No! FritzWeb and similar programs are based on the idea that you're only logged on when you're transferring data. Otherwise the connection is automatically disconnected. Since continual logging in and out severely reduces your anonymity (Why?), support for FritzWeb or similar programs is not planned. Instead, we hope that flat rates will become cheaper so that this problem no longer exists.
Yes! Start JAP on the server. Under "Config/Portlistener", deactivate "Allow access to JAP from localhost only" so that other computers can use JAP to surf.
On the other computers, configure the browser as you would for local JAP use. The only exception is that instead of localhost or 127.0.0.1 as the server address, you need to use the actual address of the server with JAP running on it.
