The script works fine on his box, x86. But on my box, sparc, I seem to have a limitation of 854 rules before I start to get errors and am unable to add anymore rules. Is there a maximum number of rules per chain? or overall? Here is the information on my Sparc box. > null:~# iptables -t filter -I INPUT 1 -s 66.28.224.0/19 -p all -j blockme > iptables: Memory allocation problem > null:~# iptables -t filter -I INPUT 1 -s 1.2.3.4/19 -p all -j blockme > iptables: Memory allocation problem > null:~# uname -a > Linux null 2.4.21 #1 Thu Aug 7 20:30:12 EDT 2003 sparc64 GNU/Linux > null:~# > null:~# iptables -L blockme > Chain blockme(854 references) > target prot opt source destination > DROP all -- anywhere anywhere Here is the info about my buddy's. x86 box > root@darkside:/etc/rc.d# uname -a; iptables -L blockme; iptables > --version > Linux darkside 2.5.50-ac1 #3 SMP Sun Feb 9 10:21:53 PST 2003 i686 > unknown > Chain blockme(3966 references) > target prot opt source destination > DROP all -- anywhere anywhere > iptables v1.2.7a Any help is greatly appreciated. -r0b
