Hi,
The ipt_TARPIT module uses sysctl_ip_default_ttl
variable but kernel doesn't export this symbol.
ipt_TARPIT.c:
(...)
/* Adjust IP TTL */
#ifdef CONFIG_SYSCTL
nskb->nh.iph->ttl = sysctl_ip_default_ttl;
#else
nskb->nh.iph->ttl = IPDEFTTL;
#endif
(...)
Finally we get undefined symbol in TARPIT module.
