Public bug reported:
Version: ufw 0.36
Ubuntu Version: 20.04.3 LTS
There doesn't appear to be a Python method for accessing IPv4 and IPv6
rules in a distinguishable manner.
In the source code (root/src/backend.py) there is an object that stores
IPv4 and IPv6 rules in separate lists. Those lists are then accessed
with the following method:
def get_rules(self):
'''Return list of all rules'''
return self.rules + self.rules6
The issue with this is that the returned list doesn't contain an
indication of what IP version each item corresponds to and would display
something like the following.
1 allow 22/tcp
2 allow 80
3 allow 443
4 allow 22/tcp
5 allow 80
6 allow 443
I don't currently see a way to distinguish between IPv4 and IPv6 rules other
than accessing the lists in the backend object directly (but I don't think this
is best practice). E.g.:
rules_ipv4 = backend.rules
rules_ipv6 = backend.rules6
One possible fix would be to add functions that return only the IPv4 or IPv6
rules. E.g.:
def get_rules_ipv4(self):
'''Return list of all ipv4 rules'''
return self.rules
def get_rules_ipv6(self):
'''Return list of all ipv6 rules'''
return self.rules6
