hi,
i modified kernel so that it will create
/proc/net/myproc file entry.
the function of this entry is to crate a 16 byte char
string from random no.s
i used net_srandom and net_random and sys_time for
that puspose. the problem is that i write program to
generate string after 120 seconds but it is changing
contents of myproc file every seconds. what can i do?
Also i am getting ipt_hook: happy cracking. message
again and again why?
regards,
parag.

You're sending out IP packets which don't even contain the IP header,
and you're running connection tracking or some filtering.
The message is not serious.

may be you're sleeping for 120 instead of 120*HZ, which
means you're really sleeping 1.2s on x86.

iptable_mangle.c comment reads 'root is playing with
raw sockets' above this message. It means that you're
sending too short IP packets (len < 20 bytes) or packets
with the IHL field < 5. It's just a harmless message.

Willy
