Yes, I have a README.sysctl file in the /etc/sysctl.d directory that explains the process as you do (with certain precisions). Simply using the command 'net.ipv4.tcp_challenge_ack_limit = 999999999' as root sets the value, but does not survive a reboot. Running 'sysctl -p' with no argument after having issued the above command does nothing but reread '/etc/sysctl.conf' (and gives no output). 'sysctl -p xxx.conf' echos the new value in xxx.conf. > ...Bob > > -- Même l’avenir n’est plus ce qu’il était. Paul Valéry
