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.

.SH "DESCRIPTION"
\fBipset\fR
is used to set up, maintain and inspect so called IP sets in the Linux
kernel. Depending on the type of the set, an IP set may store IP(v4/v6)
addresses, (TCP/UDP) port numbers, IP and MAC address pairs, IP address
and port number pairs, etc. See the set type definitions below.
.PP
\fBIptables\fR
matches and targets referring to sets create references, which
protect the given sets in the kernel. A set cannot be destroyed
while there is a single reference pointing to it.
.SH "OPTIONS"
The options that are recognized by
\fBipset\fR
can be divided into several different groups.
.SS COMMANDS
These options specify the desired action to perform. Only one of them
can be specified on the command line unless otherwise specified below.
For all the long versions of the command names, you need to use only enough
letters to ensure that
\fBipset\fR
can differentiate it from all other commands. The
\fBipset\fR
parser follows the order here when looking for the shortest match
in the long command names.
.TP
\fBn\fP, \fBcreate\fP \fISETNAME\fP \fITYPENAME\fP [ \fICREATE\-OPTIONS\fP ]
Create a set identified with setname and specified type. The type may require
type specific options. If the
\fB\-exist\fR
option is specified,
\fBipset\fR
ignores the error otherwise raised when the same set (setname and create parameters
are identical) already exists.
.TP
\fBadd\fP \fISETNAME\fP \fIADD\-ENTRY\fP [ \fIADD\-OPTIONS\fP ]
Add a given entry to the set. If the
\fB\-exist\fR
option is specified,
\fBipset\fR
ignores if the entry already added to the set.
.TP
\fBdel\fP \fISETNAME\fP \fIDEL\-ENTRY\fP [ \fIDEL\-OPTIONS\fP ]
Delete an entry from a set. If the
\fB\-exist\fR
option is specified,
\fBipset\fR
ignores if the entry does not added to (already expired from) the set.
.TP
\fBtest\fP \fISETNAME\fP \fITEST\-ENTRY\fP [ \fITEST\-OPTIONS\fP ]
Test wether an entry is in a set or not. Exit status number is zero
if the tested entry is in the set and nonzero if it is missing from
the set.
.TP
\fBx\fP, \fBdestroy\fP [ \fISETNAME\fP ]
Destroy the specified set or all the sets if none is given.
If the set has got reference(s), nothing is done and no set destroyed.
.TP
\fBlist\fP [ \fISETNAME\fP ] [ \fIOPTIONS\fP ]
List the header data and the entries for the specified set, or for
all sets if none is given. The
\fB\-resolve\fP
option can be used to force name lookups (which may be slow). When the
\fB\-sorted\fP
option is given, the entries are listed sorted (if the given set
type supports the operation). The option
\fB\-output\fR
can be used to control the format of the listing:
\fBplain\fR, \fBsave\fR or \fBxml\fR.
(The default is
\fBplain\fR.)
If the option
\fB\-name\fR
is specified, just the names of the existing sets are listed. If the option
\fB\-terse\fR
is specified, just the set names and headers are listed.
.TP
\fBsave\fP [ \fISETNAME\fP ]
Save the given set, or all sets if none is given
to stdout in a format that
\fBrestore\fP
can read.
.TP
\fBrestore\fP
Restore a saved session generated by
\fBsave\fP.
The saved session can be fed from stdin.
.TP
\fBflush\fP [ \fISETNAME\fP ]
Flush all entries from the specified set or flush
all sets if none is given.
.TP
\fBe\fP, \fBrename\fP \fISETNAME\-FROM\fP \fISETNAME\-TO\fP
Rename a set. Set identified by
\fISETNAME\-TO\fR
must not exist.
.TP
\fBw\fP, \fBswap\fP \fISETNAME\-FROM\fP \fISETNAME\-TO\fP
Swap the content of two sets, or in another words,
exchange the name of two sets. The referred sets must exist and
identical type of sets can be swapped only.
.TP
\fBhelp\fP [ \fITYPENAME\fP ]
Print help and set type specific help if
\fITYPENAME\fR
is specified.
.TP
\fBversion\fP
Print program version.
.TP
\fB\-\fP
If a dash is specified as command, then
\fBipset\fR
enters a simple interactive mode and the commands are read from the standard input.
The interactive mode can be finished by entering the pseudo\-command
\fBquit\fR.
.P
.SS "OTHER OPTIONS"
The following additional options can be specified. The long option names
cannot be abbreviated.
.TP
\fB\-!\fP, \fB\-exist\fP
Ignore errors when the exactly the same set is to be created or already
added entry is added or missing entry is deleted.
.TP
\fB\-o\fP, \fB\-output\fP { \fBplain\fR | \fBsave\fR | \fBxml\fR }
Select the output format to the
\fBlist\fR
command.
.TP
\fB\-q\fP, \fB\-quiet\fP
Suppress any output to stdout and stderr.
\fBipset\fR
will still exit with error if it cannot continue.
.TP
\fB\-r\fP, \fB\-resolve\fP
When listing sets, enforce name lookup. The
program will try to display the IP entries resolved to
host names which requires
\fBslow\fR
DNS lookups.
.TP
\fB\-s\fP, \fB\-sorted\fP
Sorted output. When listing sets entries are listed sorted. Not supported yet.
.TP
\fB\-n\fP, \fB\-name\fP
List just the names of the existing sets, i.e. suppress listing of set headers and members.
.TP
\fB\-t\fP, \fB\-terse\fP
List the set names and headers, i.e. suppress listing of set members.
.SH "SET TYPES"
A set type comprises of the storage method by which the data is stored and
the data type(s) which are stored in the set. Therefore the
\fITYPENAME\fR
parameter of the
\fBcreate\fR
command follows the syntax
\fITYPENAME\fR := \fImethod\fR\fB:\fR\fIdatatype\fR[\fB,\fR\fIdatatype\fR[\fB,\fR\fIdatatype\fR]]
where the current list of the methods are
\fBbitmap\fR, \fBhash\fR, and \fBlist\fR and the possible data types
are \fBip\fR, \fBnet\fR, \fBmac\fR, \fBport\fR and \fBiface\fR.
The dimension of a set is equal to the number of data types in its type name.
When adding, deleting or testing entries in a set, the same comma separated
data syntax must be used for the entry parameter of the commands, i.e
ipset add foo ipaddr,portnum,ipaddr
The \fBbitmap\fR and \fBlist\fR types use a fixed sized storage. The \fBhash\fR
types use a hash to store the elements. In order to avoid clashes in the hash,
a limited number of chaining, and if that is exhausted, the doubling of the hash size
is performed when adding entries by the
\fBipset\fR
command. When entries added by the
\fBSET\fR
target of
\fBiptables/ip6tables\fR,
then the hash size is fixed and the set won't be duplicated, even if the new
entry cannot be added to the set.
All set types support the optional
\fBtimeout\fR \fIvalue\fR
parameter when creating a set and adding entries. The value of the \fBtimeout\fR
parameter for the \fBcreate\fR command means the default timeout value (in seconds)
for new entries. If a set is created with timeout support, then the same
\fBtimeout\fR option can be used to specify non\-default timeout values
when adding entries. Zero timeout value means the entry is added permanent to the set.
The timeout value of already added elements can be changed by readding the element
using the \fB\-exist\fR option.
.SS bitmap:ip
The \fBbitmap:ip\fR set type uses a memory range to store either IPv4 host
(default) or IPv4 network addresses. A \fBbitmap:ip\fR type of set can store up
to 65536 entries.
.PP
\fICREATE\-OPTIONS\fR := \fBrange\fP \fIfromip\fP\-\fItoip\fR|\fIip\fR/\fIcidr\fR [ \fBnetmask\fP \fIcidr\fP ] [ \fBtimeout\fR \fIvalue\fR ]
.PP
\fIADD\-ENTRY\fR := { \fIip\fR | \fIfromip\fR\-\fItoip\fR | \fIip\fR/\fIcidr\fR }
.PP
\fIADD\-OPTIONS\fR := [ \fBtimeout\fR \fIvalue\fR ]
.PP
\fIDEL\-ENTRY\fR := { \fIip\fR | \fIfromip\fR\-\fItoip\fR | \fIip\fR/\fIcidr\fR }
.PP
\fITEST\-ENTRY\fR := \fIip\fR
.PP
Mandatory \fBcreate\fR options:
.TP
\fBrange\fP \fIfromip\fP\-\fItoip\fR|\fIip\fR/\fIcidr\fR
Create the set from the specified inclusive address range expressed in an
IPv4 address range or network. The size of the range (in entries) cannot exceed
the limit of maximum 65536 elements.
.PP
Optional \fBcreate\fR options:
.TP
\fBnetmask\fP \fIcidr\fP
When the optional \fBnetmask\fP parameter specified, network addresses will be
stored in the set instead of IP host addresses. The \fIcidr\fR prefix value must be
between 1\-32.
An IP address will be in the set if the network address, which is resulted by
masking the address with the specified netmask calculated from the prefix,
can be found in the set.
.PP
The \fBbitmap:ip\fR type supports adding or deleting multiple entries in one
command.
.PP
Examples:
.IP
ipset create foo bitmap:ip range 192.168.0.0/16
.IP
ipset add foo 192.168.1/24
.IP
ipset test foo 192.168.1.1
.SS bitmap:ip,mac
The \fBbitmap:ip,mac\fR set type uses a memory range to store IPv4 and a MAC address pairs. A \fBbitmap:ip,mac\fR type of set can store up to 65536 entries.
.PP
\fICREATE\-OPTIONS\fR := \fBrange\fP \fIfromip\fP\-\fItoip\fR|\fIip\fR/\fIcidr\fR [ \fBtimeout\fR \fIvalue\fR ]
.PP
\fIADD\-ENTRY\fR := \fIip\fR[,\fImacaddr\fR]
.PP
\fIADD\-OPTIONS\fR := [ \fBtimeout\fR \fIvalue\fR ]
.PP
\fIDEL\-ENTRY\fR := \fIip\fR[,\fImacaddr\fR]
.PP
\fITEST\-ENTRY\fR := \fIip\fR[,\fImacaddr\fR]
.PP
Mandatory options to use when creating a \fBbitmap:ip,mac\fR type of set:
.TP
\fBrange\fP \fIfromip\fP\-\fItoip\fR|\fIip\fR/\fIcidr\fR
Create the set from the specified inclusive address range expressed in an
IPv4 address range or network. The size of the range cannot exceed the limit
of maximum 65536 entries.
.PP
The \fBbitmap:ip,mac\fR type is exceptional in the sense that the MAC part can
be left out when adding/deleting/testing entries in the set. If we add an entry
without the MAC address specified, then when the first time the entry is
matched by the kernel, it will automatically fill out the missing MAC address with the
source MAC address from the packet. If the entry was specified with a timeout value,
the timer starts off when the IP and MAC address pair is complete.
.PP
The \fBbitmap:ip,mac\fR type of sets require two \fBsrc/dst\fR parameters of
the \fBset\fR match and \fBSET\fR target netfilter kernel modules and the second
one must be \fBsrc\fR to match, add or delete entries because the \fBset\fR match
and \fBSET\fR target have access to the source MAC address only.
.PP
Examples:
.IP
ipset create foo bitmap:ip,mac range 192.168.0.0/16
.IP
ipset add foo 192.168.1.1,12:34:56:78:9A:BC
.IP
ipset test foo 192.168.1.1
.SS bitmap:port
The \fBbitmap:port\fR set type uses a memory range to store port numbers
and such a set can store up to 65536 ports.
.PP
\fICREATE\-OPTIONS\fR := \fBrange\fP \fIfromport\fP\-\fItoport [ \fBtimeout\fR \fIvalue\fR ]
.PP
\fIADD\-ENTRY\fR := { \fIport\fR | \fIfromport\fR\-\fItoport\fR }
.PP
\fIADD\-OPTIONS\fR := [ \fBtimeout\fR \fIvalue\fR ]
.PP
\fIDEL\-ENTRY\fR := { \fIport\fR | \fIfromport\fR\-\fItoport\fR }
.PP
\fITEST\-ENTRY\fR := \fIport\fR
.PP
Mandatory options to use when creating a \fBbitmap:port\fR type of set:
.TP
\fBrange\fP \fIfromport\fP\-\fItoport\fR
Create the set from the specified inclusive port range.
.PP
The \fBset\fR match and \fBSET\fR target netfilter kernel modules interpret
the stored numbers as TCP or UDP port numbers.
.PP
Examples:
.IP
ipset create foo bitmap:port range 0\-1024
.IP
ipset add foo 80
.IP
ipset test foo 80
.SS hash:ip
The \fBhash:ip\fR set type uses a hash to store IP host addresses (default) or
network addresses. Zero valued IP address cannot be stored in a \fBhash:ip\fR
type of set.
.PP
\fICREATE\-OPTIONS\fR := [ \fBfamily\fR { \fBinet\fR | \fBinet6\fR } ] | [ \fBhashsize\fR \fIvalue\fR ] [ \fBmaxelem\fR \fIvalue\fR ] [ \fBnetmask\fP \fIcidr\fP ] [ \fBtimeout\fR \fIvalue\fR ]
.PP
\fIADD\-ENTRY\fR := \fIipaddr\fR
.PP
\fIADD\-OPTIONS\fR := [ \fBtimeout\fR \fIvalue\fR ]
.PP
\fIDEL\-ENTRY\fR := \fIipaddr\fR
.PP
\fITEST\-ENTRY\fR := \fIipaddr\fR
.PP
Optional \fBcreate\fR options:
.TP
\fBfamily\fR { \fBinet\fR | \fBinet6\fR }
The protocol family of the IP addresses to be stored in the set. The default is
\fBinet\fR, i.e IPv4.
.TP
\fBhashsize\fR \fIvalue\fR
The initial hash size for the set, default is 1024. The hash size must be a power
of two, the kernel automatically rounds up non power of two hash sizes to the first
correct value.
.TP
\fBmaxelem\fR \fIvalue\fR
The maximal number of elements which can be stored in the set, default 65536.
.TP
\fBnetmask\fP \fIcidr\fP
When the optional \fBnetmask\fP parameter specified, network addresses will be
stored in the set instead of IP host addresses. The \fIcidr\fP prefix value must be
between 1\-32 for IPv4 and between 1\-128 for IPv6. An IP address will be in the set
if the network address, which is resulted by masking the address with the netmask
calculated from the prefix, can be found in the set.
.PP
For the \fBinet\fR family one can add or delete multiple entries by specifying
a range or a network:
.PP
\fIipaddr\fR := { \fIip\fR | \fIfromaddr\fR\-\fItoaddr\fR | \fIip\fR/\fIcidr\fR }
.PP
Examples:
.IP
ipset create foo hash:ip netmask 30
.IP
ipset add foo 192.168.1.0/24
.IP
ipset test foo 192.168.1.2
.SS hash:net
The \fBhash:net\fR set type uses a hash to store different sized IP network addresses.
Network address with zero prefix size cannot be stored in this type of sets.
.PP
\fICREATE\-OPTIONS\fR := [ \fBfamily\fR { \fBinet\fR | \fBinet6\fR } ] | [ \fBhashsize\fR \fIvalue\fR ] [ \fBmaxelem\fR \fIvalue\fR ] [ \fBtimeout\fR \fIvalue\fR ]
.PP
\fIADD\-ENTRY\fR := \fInetaddr\fR
.PP
\fIADD\-OPTIONS\fR := [ \fBtimeout\fR \fIvalue\fR ]
.PP
\fIDEL\-ENTRY\fR := \fInetaddr\fR
.PP
\fITEST\-ENTRY\fR := \fInetaddr\fR
.PP
where
\fInetaddr\fR := \fIip\fR[/\fIcidr\fR]
.PP
Optional \fBcreate\fR options:
.TP
\fBfamily\fR { \fBinet\fR | \fBinet6\fR }
The protocol family of the IP addresses to be stored in the set. The default is
\fBinet\fR, i.e IPv4.
.TP
\fBhashsize\fR \fIvalue\fR
The initial hash size for the set, default is 1024. The hash size must be a power
of two, the kernel automatically rounds up non power of two hash sizes to the first
correct value.
.TP
\fBmaxelem\fR \fIvalue\fR
The maximal number of elements which can be stored in the set, default 65536.
.PP
For the \fBinet\fR family one can add or delete multiple entries by specifying
a range, which is converted internally to network(s) equal to the range:
.PP
\fInetaddr\fR := { \fIip\fR[/\fIcidr\fR] | \fIfromaddr\fR\-\fItoaddr\fR }
.PP
When adding/deleting/testing entries, if the cidr prefix parameter is not specified,
then the host prefix value is assumed. When adding/deleting entries, the exact
element is added/deleted and overlapping elements are not checked by the kernel.
When testing entries, if a host address is tested, then the kernel tries to match
the host address in the networks added to the set and reports the result accordingly.
.PP
From the \fBset\fR netfilter match point of view the searching for a match
always starts from the smallest size of netblock (most specific
prefix) to the largest one (least specific prefix) added to the set.
When adding/deleting IP addresses to the set by the \fBSET\fR netfilter target,
it will be added/deleted by the most specific prefix which can be found in the
set, or by the host prefix value if the set is empty.
.PP
The lookup time grows linearly with the number of the different prefix
values added to the set.
.PP
Examples:

.SS hash:ip,port
The \fBhash:ip,port\fR set type uses a hash to store IP address and port number pairs.
The port number is interpreted together with a protocol (default TCP) and zero
protocol number cannot be used.
.PP

Optional \fBcreate\fR options:
.TP
\fBfamily\fR { \fBinet\fR | \fBinet6\fR }
The protocol family of the IP addresses to be stored in the set. The default is
\fBinet\fR, i.e IPv4.
.TP
\fBhashsize\fR \fIvalue\fR
The initial hash size for the set, default is 1024. The hash size must be a power
of two, the kernel automatically rounds up non power of two hash sizes to the first
correct value
.TP
\fBmaxelem\fR \fIvalue\fR
The maximal number of elements which can be stored in the set, default 65536.
.PP
For the \fBinet\fR family one can add or delete multiple entries by specifying
a range or a network of IPv4 addresses in the IP address part of the entry:
.PP
\fIipaddr\fR := { \fIip\fR | \fIfromaddr\fR\-\fItoaddr\fR | \fIip\fR/\fIcidr\fR }
.PP
The
[\fIproto\fR:]\fIport\fR
part of the elements may be expressed in the following forms, where the range
variations are valid when adding or deleting entries:
.TP
\fIportname[\-portname]\fR
TCP port or range of ports expressed in TCP portname identifiers from /etc/services
.TP
\fIportnumber[\-portnumber]\fR
TCP port or range of ports expressed in TCP port numbers
.TP
\fBtcp\fR|\fBsctp\fR|\fBudp\fR|\fBudplite\fR:\fIportname\fR|\fIportnumber\fR[\-\fIportname\fR|\fIportnumber\fR]
TCP, SCTP, UDP or UDPLITE port or port range expressed in port name(s) or port number(s)
.TP
\fBicmp\fR:\fIcodename\fR|\fItype\fR/\fIcode\fR
ICMP codename or type/code. The supported ICMP codename identifiers can always
be listed by the help command.
.TP
\fBicmpv6\fR:\fIcodename\fR|\fItype\fR/\fIcode\fR
ICMPv6 codename or type/code. The supported ICMPv6 codename identifiers can always
be listed by the help command.
.TP
\fIproto\fR:0
All other protocols, as an identifier from /etc/protocols or number. The pseudo
port number must be zero.
.PP
The \fBhash:ip,port\fR type of sets require
two \fBsrc\fR/\fBdst\fR parameters of the \fBset\fR match and \fBSET\fR
target kernel modules.
.PP
Examples:
.IP
ipset create foo hash:ip,port
.IP
ipset add foo 192.168.1.0/24,80\-82
.IP
ipset add foo 192.168.1.1,udp:53
.IP
ipset add foo 192.168.1.1,vrrp:0
.IP
ipset test foo 192.168.1.1,80
.SS hash:net,port
The \fBhash:net,port\fR set type uses a hash to store different sized IP network
address and port pairs. The port number is interpreted together with a protocol
(default TCP) and zero protocol number cannot be used. Network
address with zero prefix size is not accepted either.

For the \fInetaddr\fR part of the elements
see the description at the \fBhash:net\fR set type. For the
[\fIproto\fR:]\fIport\fR
part of the elements see the description at the
\fBhash:ip,port\fR set type.
.PP
When adding/deleting/testing entries, if the cidr prefix parameter is not specified,
then the host prefix value is assumed. When adding/deleting entries, the exact
element is added/deleted and overlapping elements are not checked by the kernel.
When testing entries, if a host address is tested, then the kernel tries to match
the host address in the networks added to the set and reports the result accordingly.
.PP
From the \fBset\fR netfilter match point of view the searching for a match
always starts from the smallest size of netblock (most specific
prefix) to the largest one (least specific prefix) added to the set.
When adding/deleting IP
addresses to the set by the \fBSET\fR netfilter target, it will be
added/deleted by the most specific prefix which can be found in the
set, or by the host prefix value if the set is empty.
.PP
The lookup time grows linearly with the number of the different prefix
values added to the set.
.PP
Examples:
.IP
ipset create foo hash:net,port
.IP
ipset add foo 192.168.0/24,25

.PP
The lookup time grows linearly with the number of the different \fIcidr\fR

.PP
The \fBhash:ip,port,net\fR type of sets require three \fBsrc\fR/\fBdst\fR parameters of
the \fBset\fR match and \fBSET\fR target kernel modules.
.PP
Examples:

address and interface name pairs. Network address with zero prefix size is not
accepted.

The protocol family of the IP addresses to be stored in the set. The default is
\fBinet\fR, i.e IPv4.
.TP
\fBhashsize\fR \fIvalue\fR
The initial hash size for the set, default is 1024. The hash size must be a power

When adding/deleting IP
addresses to the set by the \fBSET\fR netfilter target, it will be
added/deleted by the most specific prefix which can be found in the
set, or by the host prefix value if the set is empty.
.PP
The second direction parameter of the \fBset\fR match and
\fBSET\fR target modules corresponds to the incoming/outgoing interface
: \fBsrc\fR to the incoming, while \fBdst\fR to the outgoing. When
the interface is flagged with \fBphysdev:\fR, the interface is interpreted
as the incoming/outgoing bridge port.
.PP
The lookup time grows linearly with the number of the different prefix
values added to the set.
.PP
The internal restriction of the \fBhash:net,iface\fR set type is that
the same network prefix cannot be stored with more than 64 different interfaces
in a single set.
.PP
Examples:
.IP
ipset create foo hash:net,iface
.IP
ipset add foo 192.168.0/24,eth0
.IP
ipset add foo 10.1.0.0/16,eth1
.IP
ipset test foo 192.168.0/24,eth0
.SS list:set
The \fBlist:set\fR type uses a simple list in which you can store
set names.
.PP
\fICREATE\-OPTIONS\fR := [ \fBsize\fR \fIvalue\fR ] [ \fBtimeout\fR \fIvalue\fR ]
.PP
\fIADD\-ENTRY\fR := \fIsetname\fR [ { \fBbefore\fR | \fBafter\fR } \fIsetname\fR ]

.PP
Optional \fBcreate\fR options:
.TP
\fBsize\fR \fIvalue\fR
The size of the list, the default is 8.
.PP
By the \fBipset\fR commad you can add, delete and test set names in a
\fBlist:set\fR type of set.
.PP
By the \fBset\fR match or \fBSET\fR target of netfilter
you can test, add or delete entries in the sets added to the \fBlist:set\fR
type of set. The match will try to find a matching entry in the sets and
the target will try to add an entry to the first set to which it can be added.
The number of direction options of the match and target are important: sets which
require more parameters than specified are skipped, while sets with equal
or less parameters are checked, elements added/deleted. For example if \fIa\fR and
\fIb\fR are \fBlist:set\fR type of sets then in the command
.IP
iptables \-m set \-\-match\-set a src,dst \-j SET \-\-add\-set b src,dst
.PP
the match and target will skip any set in \fIa\fR and \fIb\fR
which stores data triples, but will match all sets with single or double
data storage in \fIa\fR set and stop matching at the first successful set,
and add src to the first single or src,dst to the first double data storage set
in \fIb\fR to which the entry can be added. You can imagine a \fBlist:set\fR
type of set as an ordered union of the set elements.
.PP
Please note: by the \fBipset\fR commad you can add, delete and \fBtest\fR
the setnames in a \fBlist:set\fR type of set, and \fBnot\fR the presence of
a set's member (such as an IP address).
.SH "GENERAL RESTRICTIONS"
Zero valued set entries cannot be used with hash methods. Zero protocol value with ports
cannot be used.
.SH "COMMENTS"
If you want to store same size subnets from a given network
(say /24 blocks from a /8 network), use the \fBbitmap:ip\fR set type.
If you want to store random same size networks (say random /24 blocks),
use the \fBhash:ip\fR set type. If you have got random size of netblocks,
use \fBhash:net\fR.
.PP
Backward compatibility is maintained and old \fBipset\fR syntax is still supported.
.PP
The \fBiptree\fR and \fBiptreemap\fR set types are removed: if you refer to them,
they are automatically replaced by \fBhash:ip\fR type of sets.
.SH "DIAGNOSTICS"
Various error messages are printed to standard error. The exit code
is 0 for correct functioning.
.SH "BUGS"
Bugs? No, just funny features. :\-)
OK, just kidding...
