pyroman is a firewall configuration utility.
It will compile a set of configuration files to iptables statements to
setup IP packet filtering for you.
While it is not necessary for operating and using Pyroman, you should
have understood how IP, TCP, UDP, ICMP and the other commonly used
Internet protocols work and interact. You should also have understood
the basics of iptables in order to make use of the full functionality.
pyroman does not try to hide all the iptables complexity from you, but
tries to provide you with a convenient way of managing a complex
networks firewall. For this it offers a compact syntax to add new
firewall rules, while still exposing access to add arbitrary iptables
Load the rules from directory RULESDIR instead of the default
directory (usually /etc/pyroman )
Wait SECONDS seconds after applying the changes for the user to
type OK to confirm he can still access the firewall. This
implies --safe but allows you to use a different timeout.
Print a summary of the command line options and exit.
Print the version number of pyroman and exit.
-s, --safe, safe
When the firewall was committed, wait 30 seconds for the user to
type OK to confirm, that he can still access the firewall (i.e.
the network connection wasn’t blocked by the firewall).
Otherwise, the firewall changes will be undone, and the firewall
will be restored to the previous state. Use the
--timeout=SECONDS option to change the timeout.
Don’t actually run iptables. This can be used to check if
pyroman accepts the configuration files.
Instead of running iptables, output the generated rules.
Instead of running iptables, output the generated rules. Each
statement will have one comment line explaining how this rules
was generated. This will usually include the filename and line
number, and is useful for debugging.
Configuration of pyroman consists of a number of files in the directory
/etc/pyroman. These files are in python syntax, although you do not
need to be a python programmer to use these rules. There is only a
small number of statements you need to know:
Define a new host or network
Define a new interface (group)
Add a new service alias (note that you can always use e.g.
www/tcp to reference the www tcp service as defined in
Define a new NAT (Network Address Translation) rule
allow Allow a service, client, server combination
reject Reject access for this service, client, server combination
drop Drop packets for this service, client, server combination
Add a rule for this service, client, server and target
Add an arbitrary iptables statement to be executed at beginning
Add an arbitrary iptables statement to be executed at the end
Detailed parameters for these functions can be looked up by caling
