This is the ipset source tree. Follow the next steps to install ipset.
|
||||
If you upgrade from an earlier 5.x release, please read the UPGRADE
|
||||
instructions too.
|
||||
|
||||
0. You need the source tree of your kernel (version >= 2.6.34)
|
||||
and it have to be configured with ip6tables support enabled,
|
||||
modules compiled. Please apply the netlink.patch against your kernel
|
||||
tree, which adds the new subsystem identifier for ipset.
|
||||
|
||||
Recompile and install the patched kernel and its modules. Please note,
|
||||
you have to run the patched kernel for ipset to work.
|
||||
|
||||
The ipset source code depends on the libmnl library so the library
|
||||
must be installed. You can download the libmnl library from
|
||||
|
||||
git://git.netfilter.org/libmnl.git
|
||||
|
||||
1. Initialize the compiling environment for ipset. The packages automake,
|
||||
autoconf and libtool are required.
|
||||
|
||||
% ./autogen.sh
|
||||
|
||||
2. Run `./configure` and then compile the ipset binary and the kernel
|
||||
modules.
|
||||
|
||||
Configure parameters can be used to to override the default path
|
||||
to the kernel source tree (/lib/modules/`uname -r`/build),
|
||||
the maximum number of sets (256), the default hash sizes (1024).
|
||||
See `./configure --help`.
|
||||
|
||||
% ./configure
|
||||
% make
|
||||
% make modules
|
||||
|
||||
3. Install the binary and the kernel modules
|
||||
|
||||
# make install
|
||||
# make modules_install
|
||||
|
||||
After installing the modules, you can run the testsuite as well.
|
||||
Please note, several assumptions must be met for the testsuite:
|
||||
|
||||
- no sets defined
|
||||
- iptables/ip6tables rules are not set up
|
||||
- the destination for kernel logs is /var/log/kern.log
|
||||
- the networks 10.255.255.0/24 and 1002:1002:1002:1002::/64
|
||||
are not in use
|
||||
- sendip utility is installed
|
||||
|
||||
# make tests
|
||||
|
||||
4. Cleanup the source tree
|
||||
|
||||
% make clean
|
||||
% make modules_clean
|
||||
|
||||
That's it!
|
||||
|
||||
Read the ipset(8) and iptables(8), ip6tables(8) manpages on how to use
|
||||
ipset and its match and target from iptables.
|
||||
|
||||
Compatibilities and incompatibilities:
|
||||
|
||||
- The ipset 6.x userspace utility contains a backward compatibility
|
||||
interface to support the commandline syntax of ipset 4.x.
|
||||
The commandline syntax of ipset 6.x is fully compatible with 5.x.
|
||||
- The ipset 6.x userspace utility can't talk to the kernel part of ipset 5.x
|
||||
or 4.x.
|
||||
- The ipset 6.x kernel part can't talk to the userspace utility from
|
||||
ipset 5.x or 4.x.
|
||||
- The ipset 6.x kernel part can work together with the set match and SET
|
||||
target from iptables 1.4.7 and below, however if you need the IPv6 support
|
||||
from ipset 6.x, then you have to use iptables 1.4.8 or above.
|
||||
|
||||
The ipset 6.x can interpret the commandline syntax of ipset 4.x, however
|
||||
some internal changes mean different behaviour:
|
||||
|
||||
- The "--matchunset" flag for the macipmap type is ignored and not used
|
||||
anymore.
|
||||
- The "--probes" and "--resize" parameters of the hash types are ignored
|
||||
and not used anymore.
|
||||
- The "--from", "--to" and "--network" parameters of the ipporthash,
|
||||
ipportiphash and ipportnethash types are ignored and not used anymore.
|
||||
- The hash types are not resized when new entries are added by the SET
|
||||
target. If you use a set together with the SET target, create it with
|
||||
the proper size because it won't be resized automatically.
|
||||
- The iptree, iptreemap types are not implemented in ipset 6.x. The types
|
||||
are automatically substituted with the hash:ip type.

TARPIT only works at the TCP level, and is totally application agnostic. This
|
||||
module will answer a TCP request and play along like a listening server, but
|
||||
aside from sending an ACK or RST, no data is sent. Incoming packets are ignored
|
||||
and dropped. The attacker will terminate the session eventually. This module
|
||||
allows the initial packets of an attack to be captured by other software for
|
||||
inspection. In most cases this is sufficient to determine the nature of the
|
||||
attack.

|
||||
This offers similar functionality to LaBrea
|
||||
<http://www.hackbusters.net/LaBrea/> but does not require dedicated hardware or
|
||||
IPs. Any TCP port that you would normally DROP or REJECT can instead become a
|
||||
tarpit.

.TP
|

\fB\-\-tarpit\fP
|
||||
This mode completes a connection with the attacker but limits the window size
|
||||
to 0, thus keeping the attacker waiting long periods of time. While he is
|
||||
maintaining state of the connection and trying to continue every 60-240
|
||||
seconds, we keep none, so it is very lightweight. Attempts to close the
|
||||
connection are ignored, forcing the remote side to time out the connection in
|
||||
12-24 minutes. This mode is the default.
|
||||
.TP
|
||||
\fB\-\-honeypot\fP
|
||||
This mode completes a connection with the attacker, but signals a normal window
|
||||
size, so that the remote side will attempt to send data, often with some very
|
||||
nasty exploit attempts. We can capture these packets for decoding and further
|
||||
analysis. The module does not send any data, so if the remote expects an
|
||||
application level response, the game is up.
|
||||
.TP
|
||||
\fB\-\-reset\fP
|
||||
This mode is handy because we can send an inline RST (reset). It has no other
|
||||
function.
