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.

hello,
Because of i increase icmp header by 8 bytes the next layer IP headers are not
fully added to skbuff that is they become short and i am repeatedly getting
ip_hook : happy cracking message
so where can i modify the total size of alloc_skb to satisfy my constraints
for icmp header?
i got one reference mail that some person has done adding his own header to
ping packet and send it to other machine.he actually added that successfully.
i am unable to contact him. might be his email address has been changed.
regards,
parag.
