Linux IPCHAINS-HOWTO: Appendix: Using the ipfwadm-wrapper script.





9. Appendix: Using the ipfwadm-wrapper
script.
The ipfwadm-wrapper shell script should be a plug-in replacement
of ipfwadm for backwards compatibility with ipfwadm 2.3a.

The only feature it can't really handle is the `-V' option. When this is
used, a warning is given. If the `-W' option is also used, the `-V' option is
ignored. Otherwise, the script tries to find the interface name associated with
that address, using ifconfig. If that fails (such as for an
interface which is down) then it will exit with an error message.

This warning can be suppressed by either changing the `-V' to a `-W', or
directing the standard output of the script to /dev/null.

If you should find any mistakes in this script, or any changes between the
real ipfwadm and this script, please report a bug to me: send an EMail
to [e-mail] with "BUG-REPORT" in the subject. Please list your old
version of ipfwadm (ipfwadm -h), your version of
ipchains (ipchains --version), the version of the
ipfwadm wrapper script (ipfwadm-wrapper --version). Also send the
output of ipchains-save. Thanks in advance.

Mix ipchains with this ipfwadm-wrapper script at
your own peril.
