# Note on dynamic dns
|
||
# ===================
|
||
#
|
||
# I'm not particularly trying to promote freedns.afraid.org
|
||
# as a service, it just happens to be a dynamic DNS system which
|
||
# provides free (as in beer) accounts, and I'm trying to make the
|
||
# process of setting up a working server as trivial as possible.
|
||
# Other dynamic DNS systems are available, and if you're using
|
||
# something different then comment out the section within
|
||
# argument_checks and the call to dynamic_dns_freedns.
|
||
