Oh, well, RPZ is certainly a nice addon, but I wouldn't call it a simplification. Actually, BIND doesn't need a file for each host. It needs a file for each zone, which is what is called a /zone file/. So long as all virtual hosts share the same TLD, they fit on the same zone file. Bind allows different views. That feature allows you to use internal network number and names on the internal view only, in case you use the server also to maintain a public domain name. And of course, you can configure ISC DHCP to work with it. Good luck Ale --

The thing you need to know is 'rpz', Response Policy Zone. Otherwise you would have to set up a separate zone file for each of your domains. With rpz, you can just throw any hostname and IP address into one file, a sort of /etc/hosts for BIND. This is a good quick tutorial: https://www.redpill-linpro.com/sysadvent/2015/12/08/dns-rpz.html Assuming the standard BIND architecture on Debian hasn't changed in the last few years: the db.rpz file goes in /etc/bind, along with other 'system' db files. The zone definition goes in /etc/bind/named.conf.local. The 'response-policy ( zone "rpz"; );' (don't forget the semicolons) goes in /etc/bind/named.conf.options. Don't worry about the logging. When you add another host to db.rpz, don't forget to increment the serial, which tells BIND that things have changed. The tutorial shows a date-related large number for this, but you can start it at 1. If there's anything that isn't clear, look for more tutorials and compare them, I don't know any more than is in this one. Oh, always check the syslog after restarting BIND. If it finds the slightest error in a configuration file, it will silently fail to restart, or at best, not use the offending zone. -- Joe

Pointers to forums, cookbooks, etc. would be appreciated as well as hints and tips! TIA! Dennnis First you will need to read about Apache virtual hosts here: http://httpd.apache.org/docs/current/vhosts/name-based.html Basically what happens is the browser sends the name that it is trying to reach in its header and Apache uses that info to direct that request to the appropriate directory. All the different names will point to the same address ... the address of your host. To use bind for this then all your hosts on your network will have to use the bind DNS server as their DNS server. I use a debian box as my router/firewall so it is easy for me to change DNS entrys for my home network. It might be easier if your router would allow you to add entries to its DNS server. If not then you could use each machines hosts file to put in your private addresses. You will have to make up your own names. Example: host1.home cookbook.home forum.home These would all point to the address of host1 but Apache would be able to direct the requests to different directories under /var/www depending on the name used. I use this method on a VM at digital ocean to serve 4 or 5 different web sites from the one address. Your apache config might look like this: ServerName host1.home DocumentRoot "/var/www/host1" ServerName cookbook.home DocumentRoot "/var/www/cookbook" etc... Make sure all the files under /var/www are owned by www-data and group www-data (chown www-data.www-data files). -- *...Bob*

Setting up bind9/DNS
Greetings, I have apache2 installed on my local machine with a bunch of virtual hosts that I use for test and development of html, wordpress, etc. It works fine to access the virt hosts locally, but I want to access them from other systems on my local network; windows/IE of various versions, smart phones, tablets, laptops, etc. They all can access my base host name because my DSL modem/router has DHCP and DNS in it and when it sets up an address with DHCP it puts an entry in its DNS and everything is fine. (All systems on the local net use the modem/router for dns.) But nothing like this happens with the virtual hosts! I was thinking that I could setup a nameserver on my machine with enries in it for the virtual hosts and have my local network address in the list of nameservers in my modem/router, and that is where I need the help. I have installed bind9, running on buster. So how do I set up the name server and populate it with the info for my virtual hosts? Pointers to forums, cookbooks, etc. would be appreciated as well as hints and tips! TIA! Dennnis
