Hello List,

I am having problem in getting iptables recent module working for me,
so I was looking into /proc to get some clues. I see following line in
the /proc for my iptables recent rule:
# cat /proc/net/ipt_recent/badguy
src= ttl: 63 last_seen: 3301974512 oldest_pkt: 2 3301973507,

What does ttl mean? Is it time-to-live or what? What does it signify?
