builtin action dropBcast - How to disable? - I''m not subscribed to the mailing list
Hi all, I''m using Fedora Core 2, kernel 2.6.5. I''ve installed shorewall 2.1.9 from rpm package. It seems that there is a builtin action called "dropBcast" drops all broadcast packages on my ethernet interfaces base on package type "pkttype=broadcast". For a particular reason, I need all traffics of broadcast packages are allowed to pass my ethernet interfaces. I''ve searched for days on shorewall''s FAQ,troubleshooting information, errata and mailing list archives as well, but couldn''t find the answer. Therefore, I write you to ask for help. Please guide me how to allow broadcast traffice on my system. Thank you very much for your help. Best regards, Le Ngoc My (I am not subscribled to the mailing list) _______________________________ Do you Yahoo!? Declare Yourself - Register online to vote today! http://vote.yahoo.com

Look in /usr/share/shorewall that is probably where the files are. you will need to remove dropBcast from the action.Drop and action.Reject.

You should copy the files action.Drop and action.Reject to your /etc/shorewall directory and make the changes there.> > Todd > > Le wrote: > > Hi all, > > I''m using Fedora Core 2, kernel 2.6.5.

I seem to have to explain this every month or so but here goes again. The ''Reject'' and ''Drop'' common actions are *ONLY THERE TO AVOID LOG CLUTTER*. They are only invoked *JUST BEFORE THE PACKET IS GOING TO BE REJECTED OR DROPPED ANYWAY*. So removing dropBast from Drop and Reject *WILL ONLY CAUSE THESE REJECTED AND DROPPED BROADCASTS TO BE LOGGED* thereby filling your log with useless messages. *IN NO CASE DO THESE ACTIONS CAUSE TRAFFIC TO BE DROPPED/REJECTED THAT WOULD NOT BE DROPPED/REJECTED ANYWAY* So whatever the original poster''s problem with broadcasts is, it *ISN''T THE COMMON ACTIONS*. - -Tom - -- Tom Eastep \ Nothing is foolproof to a sufficiently talented fool Shoreline, \ http://shorewall.net Washington USA \ teastep@shorewall.net PGP Public Key \ https://lists.shorewall.net/teastep.pgp.key -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFBZV52O/MAbZfjDLIRAtqrAJ9xss5s7ogSHusWNcCkjEHJ0NFH0ACeN2QI Wvknecs399GoFzZ+L7kMmSo=3j7f -----END PGP SIGNATURE-----
