DNS and HTTP

The server is configured to be a caching dns server and a web proxy

The goal is to use both.

Using the DNS server

1. Set kali to use the server as DNS server

   This is a different DNS server than the one given by the DHCP server.

   In network manager, there is a flag for specifying your own DNS server instead. See e.g. this stackoverflow question.

2. Use wireshark to check that kali acutally uses the new server as DNS server.

3. Oh no! It is not working even with the correct DNS server in Kali.

   What DNS trafic is the DNS server sending and receiving?

4. Correct the DNS server used by the server.

   It is done in /etc/dnsmasq.resolv.conf. Set it to use censurfridns.dk

5. Restart the service by doing service dnsmasq restart (as root)

   If it fails, reiterate and fix.

6. Collect your notes on how you tested, concluded and fixed the issues.

Using the web proxy

1. Read up on what a webproxy is, e.g. here and here

   The server is installed with squid

2. Use the server as a webproxy

   Change the configuration in your browser, see here or find a guide specific for your browser.

   Squid is running on port tcp/3128 on the server.

3. Is it working?

   Use wireshark to show that you use the server as a proxy and that the proxy forwards the requests.

   Also, there are log files on the server in /var/log/squid. Use e.g. tail -f /var/log/squid/access.log to mnitor requests.
