Hello, I was playing with custom iptables rules and something went wrong. Now my *engine-config -g IPTablesConfig* is empty. Can some one please give a hint what should be there??:) Thanks, Arman. *********************************************************** Dr. Arman Khalatyan eScience -SuperComputing Leibniz-Institut für Astrophysik Potsdam (AIP) An der Sternwarte 16, 14482 Potsdam, Germany ***********************************************************
