|

# How do you set options:
|

#
|
||||
# 1. You can set options by name.
|
||||
# You can find the name in listener.py.
|
||||
# Example: subnet_mask
|
||||
#
|
||||
# 2. You can set options by number.
|
||||
# You can find the number in the RFC 2132.
|
||||
# Named options are preferred over unnamed options.
|
||||
# Example: option_1
|
||||
# Option 1 is the subnet mask.
|
||||
# Because subnet_mask = '255.255.255.0' is in this
|
||||
# file, the option_1 = '255.255.255.0' statement
|
||||
# is ignored.
|
||||
#
|
||||
# If you see "3.17. Domain Name" you can use
|
||||
# "Domain Name".lower().replace(" ", "_")
|
||||
# to convert it to the variable name.
|
||||
#
|
||||
# Some options do not have conversion functions
|
||||
# assigned to them so you need to use bytes.
|
||||
# Example: domain_name = b'hello.kitty.tv'
|
||||
# Again, see listener.py
