Hi All, I''m using iptables-1.2.7a on RedHat8 kernel 2.4.20. I wanted to limit the file-sharing traffic to the internet. I marked the packets with iptables: iptables -A FORWARD -t mangle -p tcp -s 192.168.1.1/24 -d ! 192.168.1.1/24 --dport 1024:1862 -j MARK --set-mark 1 iptables -A FORWARD -t mangle -p tcp -s 192.168.1.1/24 -d ! 192.168.1.1/24 --dport 1864:65535 -j MARK --set-mark 1

...1800 and 8GB ram. I installed centos 32bit so I should be able to use 4GB. My system on boot recognize 4GB ram but allocate only 2GB. Extract from dmesg: Warning only 4GB will be used. Use a PAE enabled kernel. 3200MB HIGHMEM available. 896MB LOWMEM available. Memory: 2056396k/4194304k available (2043k kernel code, 39416k reserved, 846k data, 232k init, 1179584k highmem) Why it suggest me to "Use a PAE enabled kernel."? Thanks. Giuliano.
