quering byte counts for user defined chains/rules using libiptc

[Jaroslaw Zdrzalek <zdrzalek@xxxxxxxxxx>]

dear all,

my prog, which uses libiptc, queries byte counts for a single rule in an
user defined chain (ipXXX.XXX.XXX.XXX)

here comes a sample code:
...

        

        

h
= iptc_init(tablenamefilter);

        

        

if
(!h) slog(LOG_ERR, "Can't initialize:
%s\n",iptc_strerror(errno));

        

        

        

now
= time(NULL);

        

        

        

for
(chain = iptc_first_chain(&h); chain; chain =
iptc_next_chain(&h))//ITERATE CHAINS

        

        

{

        

        

        

ip
= chain+2;//2==strlen(chainprefix);

        

        

        

if(strncmp(chain,chainprefix,2)!=0)
continue;

        

        

        

        

        

        

struct
ipt_counters *count = NULL;

        

        

        

count
= iptc_read_counter(chain, 1, &h);

        

        

        

if(count
== NULL) slog(LOG_ERR,"iptc_read_counter(%s, 1, &h); returns
NULL",chain);

        

        

        

else

        

        

        

{

        

        

        

        

bytecnt
= count->bcnt;

        

        

        

        

slog(LOG_INFO,"iptc_read_counter(%s,
1, &h); returns %u",chain,bytecnt);

        

        

        

}
......
the problem is that it always returns 0.
with iptables -L -v i get real counts

the version of iptables is 1.2.8 (stable)

if yoe have any suggestions please reply to my email,
because i am not a list member

thanks in advance

jaroslaw
