From 28b22d55615447c94c5058e0aacec612ebc27f2a Mon Sep 17 00:00:00 2001 From: Arturo Borrero Gonzalez Date: Wed, 20 Jun 2018 15:43:39 +0200 Subject: arptables: legacy renaming The original arptables tool is now the legacy version, let's rename it. A more uptodate client of the arptables tool is provided in the iptables tarball. The new tool was formerly known as arptables-compat. The new -legacy binary should have no problem if called via a symlink.

That means that a new, more modern tool exists with the same +functionality using the nf_tables framework and you are encouraged to migrate now. +The new binaries (formerly known as -compat) uses the same syntax and +semantics than this legacy one. + +You can still use this legacy tool. You should probably get some specific +information from your Linux distribution or vendor. +More docs are available at https://wiki.nftables.org + +.SH DESCRIPTION +.B arptables +is a user space tool, it is used to set up and maintain the +tables of ARP rules in the Linux kernel. These rules inspect +the ARP frames which they see. +.B arptables +is analogous to the +.B iptables +user space tool, but +.B arptables +is less complicated. + +.SS CHAINS +The kernel table is used to divide functionality into +different sets of rules. Each set of rules is called a chain. +Each chain is an ordered list of rules that can match ARP frames. If a +rule matches an ARP frame, then a processing specification tells +what to do with that matching frame. The processing specification is +called a 'target'. However, if the frame does not match the current +rule in the chain, then the next rule in the chain is examined and so forth. +The user can create new (user-defined) chains which can be used as the 'target' of a rule. + +.SS TARGETS +A firewall rule specifies criteria for an ARP frame and a frame +processing specification called a target. When a frame matches a rule, +then the next action performed by the kernel is specified by the target. +The target can be one of these values: +.IR ACCEPT , +.IR DROP , +.IR CONTINUE , +.IR RETURN , +an 'extension' (see below) or a user-defined chain. +.PP +.I ACCEPT +means to let the frame through. +.I DROP +means the frame has to be dropped. +.I CONTINUE +means the next rule has to be checked. This can be handy to know how many +frames pass a certain point in the chain or to log those frames. +.I RETURN +means stop traversing this chain and resume at the next rule in the +previous (calling) chain. +For the extension targets please see the +.B "TARGET EXTENSIONS" +section of this man page. +.SS TABLES +There is only one ARP table in the Linux +kernel. The table is +.BR filter. +You can drop the '-t filter' argument to the arptables command. +The -t argument must be the +first argument on the arptables command line, if used. +.TP +.B "-t, --table" +.br +.BR filter , +is the only table and contains two (Linux kernels 2.4.X) or three (Linux kernels 2.6.0 and later) built-in chains: +.B INPUT +(for frames destined for the host), +.B OUTPUT +(for locally-generated frames) and +.B FORWARD +(for frames being forwarded by the bridge code). The +.B FORWARD +chain doesn't exist in Linux 2.4.X kernels. +.br +.br +.SH ARPTABLES COMMAND LINE ARGUMENTS +After the initial arptables command line argument, the remaining +arguments can be divided into several different groups. These groups +are commands, miscellaneous commands, rule-specifications, match-extensions, +and watcher-extensions. +.SS COMMANDS +The arptables command arguments specify the actions to perform on the table +defined with the -t argument. If you do not use the -t argument to name +a table, the commands apply to the default filter table. +With the exception of the +.B "-Z" +command, only one command may be used on the command line at a time. +.TP +.B "-A, --append" +Append a rule to the end of the selected chain. +.TP +.B "-D, --delete" +Delete the specified rule from the selected chain. There are two ways to +use this command. The first is by specifying an interval of rule numbers +to delete, syntax: start_nr[:end_nr]. Using negative numbers is allowed, for more +details about using negative numbers, see the -I command. The second usage is by +specifying the complete rule as it would have been specified when it was added. +.TP +.B "-I, --insert" +Insert the specified rule into the selected chain at the specified rule number. +If the current number of rules equals N, then the specified number can be +between -N and N+1. For a positive number i, it holds that i and i-N-1 specify the +same place in the chain where the rule should be inserted. The number 0 specifies +the place past the last rule in the chain and using this number is therefore +equivalent with using the -A command. +.TP +.B "-R, --replace" +Replaces the specified rule into the selected chain at the specified rule number. +If the current number of rules equals N, then the specified number can be +between 1 and N. i specifies the place in the chain where the rule should be replaced. +.TP +.B "-P, --policy" +Set the policy for the chain to the given target. The policy can be +.BR ACCEPT ", " DROP " or " RETURN . +.TP +.B "-F, --flush" +Flush the selected chain. If no chain is selected, then every chain will be +flushed. Flushing the chain does not change the policy of the +chain, however. +.TP +.B "-Z, --zero" +Set the counters of the selected chain to zero. If no chain is selected, all the counters +are set to zero. The +.B "-Z" +command can be used in conjunction with the +.B "-L" +command. +When both the +.B "-Z" +and +.B "-L" +commands are used together in this way, the rule counters are printed on the screen +before they are set to zero. +.TP +.B "-L, --list" +List all rules in the selected chain. If no chain is selected, all chains +are listed. +.TP +.B "-N, --new-chain" +Create a new user-defined chain with the given name. The number of +user-defined chains is unlimited. A user-defined chain name has maximum +length of 31 characters. +.TP +.B "-X, --delete-chain" +Delete the specified user-defined chain. There must be no remaining references +to the specified chain, otherwise +.B arptables +will refuse to delete it. If no chain is specified, all user-defined +chains that aren't referenced will be removed. +.TP +.B "-E, --rename-chain" +Rename the specified chain to a new name. Besides renaming a user-defined +chain, you may rename a standard chain name to a name that suits your +taste. For example, if you like PREBRIDGING more than PREROUTING, +then you can use the -E command to rename the PREROUTING chain. If you do +rename one of the standard +.B arptables +chain names, please be sure to mention +this fact should you post a question on the +.B arptables +mailing lists. +It would be wise to use the standard name in your post. Renaming a standard +.B arptables +chain in this fashion has no effect on the structure or function +of the +.B arptables +kernel table. + +.SS MISCELLANOUS COMMANDS +.TP +.B "-V, --version" +Show the version of the arptables userspace program. +.TP +.B "-h, --help" +Give a brief description of the command syntax. +.TP +.BR "-j, --jump " "\fItarget\fP" +The target of the rule. This is one of the following values: +.BR ACCEPT , +.BR DROP , +.BR CONTINUE , +.BR RETURN , +a target extension (see +.BR "TARGET EXTENSIONS" ")" +or a user-defined chain name. +.TP +.BI "-c, --set-counters " "PKTS BYTES" +This enables the administrator to initialize the packet and byte +counters of a rule (during +.B INSERT, +.B APPEND, +.B REPLACE +operations). + +.SS RULE-SPECIFICATIONS +The following command line arguments make up a rule specification (as used +in the add and delete commands).
