The following example from the man page doesn't work on my box:

  iptables -A FORWARD -m recent --name badguy --rcheck --seconds 60 -j DROP
  iptables -A FORWARD -p tcp -i eth0 --dport 139 -m recent --name badguy --set -j DROP

It says: "iptables: No chain/target/match by that name"

What could be the reason?

My ifconfig:

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0

I see 'eth0' in your rule, but below there is no eth0.

Oops. that was just a cut&paste error, I actually had changed it,
tried everything, but w/o success.
Any other ideas what it might be?

BTW, it is a virtual private server (VPS) box, there is nothing under /boot.

Here the version info:

# uname -r
2.6.9-023stab048.4-smp

# iptables --version
iptables v1.3.6

And here the other rules iptables has accepted:

What GNU/Linux distro are you running?

I am running Debian Sid and here are my versions:

2.6.26-1-686
iptables v1.4.1.1

Here are the iptables rules that I have:
# if anybody from the list BADGUYS (and in the last 10 minutes) tries to
do anything, drop them
iptables -A INPUT --match recent --name BADGUYS --rcheck --seconds 600
-j DROP
# if anybody tries to connect to tcp:139 (windows filesharing), then add
them to the BADGUYS list and drop them
iptables -A INPUT -p tcp -i eth0 --dport 21 --match recent --name
BADGUYS --set -j DROP
iptables -A INPUT -p udp -i eth0 --dport 21 --match recent --name
BADGUYS --set -j DROP
iptables -A INPUT -p tcp -i eth0 --dport 139 --match recent --name
BADGUYS --set -j DROP
iptables -A INPUT -p tcp -i eth0 --dport 445 --match recent --name
BADGUYS --set -j DROP

Looks pretty similar to yours.

Also you could check to see if you have the module:

% lsmod | grep recent

and

% modinfo ipt_recent

The following command shows that the "ipt_recent" module is missing
in my VPS. Unfortunately it seems it can only be enabled by the hosting provider:

# cat /proc/net/ip_tables_matches
length
ttl
tcpmss
tos
multiport
limit
state
tcp
udp
icmp
