hi,all,I download patch-o-matic-ng-20051205.tar.bz2 and iptables-1.3.4.tar.bz2 from ftp.netfilter.org,and linux-2.6.13.4.tar.bz2 from www.kernel.org.but there is some error when i compile them:

-------error messages------------

CC net/ipv4/netfilter/ipt_time.o

---------------------cut here--------------------

so i read the file "ipt_time.c" and find the error is maybe at "skb->tstamp"

-------ipt_time.c------------------
static int
match(const struct sk_buff *skb,
 const struct net_device *in,
 const struct net_device *out,
 const void *matchinfo,
 int offset,
 int *hotdrop)
{
 const struct ipt_time_info *info = matchinfo; /* match info for rule */
 struct tm currenttime; /* time human readable */
 u_int8_t days_of_week[7] = {64, 32, 16, 8, 4, 2, 1};
 u_int16_t packet_time;

/* We might not have a timestamp, get one */
 if (skb->tstamp.off_sec == 0)
 __net_timestamp((struct sk_buff *)skb);

/* First we make sure we are in the date start-stop boundaries */
 if ((skb->tstamp.off_sec < info->date_start) || (skb->tstamp.off_sec > info->date_stop))
 return 0; /* We are outside the date boundaries */

/* Transform the timestamp of the packet, in a human readable form */
 localtime(skb->tstamp.off_sec, &currenttime);

/* check if we match this timestamp, we start by the days... */
 if ((days_of_week[currenttime.tm_wday] & info->days_match) != days_of_week[currenttime.tm_wday])
 return 0; /* the day doesn't match */

/* ... check the time now */
 packet_time = (currenttime.tm_hour * 60) + currenttime.tm_min;
 if ((packet_time < info->time_start) || (packet_time > info->time_stop))
 return 0;

/* here we match ! */
 return 1;
}
---------------------cut here--------------------

then i read the file "include/linux/skbuff.h",i find there is no the member "tstamp" in the struct "sk_buff"

You simply need more recent kernel (2.6.14.x) or older patch-o-matic-ng.

Best regards,

这个是第二个家伙的回答，呵呵，简单极了。

东西实在是不能求太新啊！
