Raw Notes on Bind
#!/bin/bash
#
# this is a bash script that constructs a complete bind configuration, then starts bind.
#
# Run it as root in one xterm, and test it from another xterm by typing commands like:
# host a
# and
# host 10.3.0.2
#
# The "-g" argument to bind (see last line in script) prevents bind from becoming a daemon and
# keeps it in the foreground where you can kill it with cntl-c.
# "-g" also forced bind to print its diagnostic messaged to stdout (instead of to the syslog).
#
# file_summary: full bind and resolver configuration for uml.net domain with three hosts a,b, and c at addresses 10.3.0.1, 10.3.0.2, 10.3.0.3.
#
# you can test this from another shell by running the commands:
# host a localhost
# host 10.3.0.2 localhost
# host b localhost
# host 10.3.0.3 localhost
# host c localhost
