shorewall6-accounting 5 accounting Shorewall6 Accounting file /etc/shorewall6/accounting Accounting rules exist simply to count packets and bytes in categories that you define in this file. You may display these rules and their packet and byte counters using the shorewall6 show accounting command. Beginning with Shorewall 4.4.18, the accounting structure can be created with three root chains: accountin: Rules that are valid in the INPUT chain (may not specify an output interface). accountout: Rules that are valid in the OUTPUT chain (may not specify an input interface or a MAC address). accounting: Other rules. The new structure is enabled by sectioning the accounting file in a manner similar to the rules file. The sections are INPUT, OUTPUT and FORWARD and must appear in that order (although any of them may be omitted). The first non-commentary record in the accounting file must be a section header when sectioning is used. Beginning with Shorewall 4.4.20, the ACCOUNTING_TABLE setting was added to shorewall.conf and shorewall6.conf. That setting determines the Netfilter table (filter or mangle) where the accounting rules are added. When ACCOUNTING_TABLE=mangle is specified, the available sections are PREROUTING, INPUT, OUTPUT, FORWARD and POSTROUTING. Section headers have the form: SECTION section-name When sections are enabled: A jump to a user-defined accounting chain before entries that add rules to that chain. This eliminates loops and unreferenced chains. An output interface may not be specified in the PREROUTING and INPUT sections. In the OUTPUT and POSTROUTING sections: An input interface may not be specified Jumps to a chain defined in the INPUT or PREROUTING sections that specifies an input interface are prohibited MAC addresses may not be used Jump to a chain defined in the INPUT or PREROUTING section that specifies a MAC address are prohibited. The default value of the CHAIN column is: accountin in the INPUT section accounout in the OUTPUT section accountfwd in the FORWARD section accountpre in the PREROUTING section accountpost in the POSTROUTING section Traffic addressed to the firewall goes through the rules defined in the INPUT section. Traffic originating on the firewall goes through the rules defined in the OUTPUT section. Traffic being forwarded through the firewall goes through the rules from the FORWARD sections. The columns in the file are as follows (where the column name is followed by a different name in parentheses, the different name is used in the alternate specification syntax). ACTION - {COUNT|DONE|chain[:{COUNT|JUMP}]|COMMENT comment} What to do when a matching packet is found. COUNT Simply count the match and continue with the next rule DONE Count the match and don't attempt to match any other accounting rules in the chain specified in the CHAIN column. chain[:COUNT] Where chain is the name of a chain; shorewall6 will create the chain automatically if it doesn't already exist. Causes a jump to that chain to be added to the chain specified in the CHAIN column. If :COUNT is included, a counting rule matching this entry will be added to chain. The chain may not exceed 29 characters in length and may be composed of letters, digits, dash ('-') and underscore ('_'). chain:JUMP Like the previous option without the :COUNT part. NFLOG[(nflog-parameters)] - Added in Shorewall-4.4.20. Causes each matching packet to be sent via the currently loaded logging backend (usually nfnetlink_log) where it is available to accounting daemons through a netlink socket. COMMENT The remainder of the line is treated as a comment which is attached to subsequent rules until another COMMENT line is found or until the end of the file is reached. To stop adding comments to rules, use a line with only the word COMMENT. CHAIN - {-|chain} The name of a chain. If specified as - the accounting chain is assumed. This is the chain where the accounting rule is added. The chain will be created if it doesn't already exist. The chain may not exceed 29 characters in length. SOURCE - {-|any|all|interface|interface:[address]|address} Packet Source. The name of an interface, an address (host or net) or an interface name followed by ":" and a host or net address. DESTINATION (dest) - {-|any|all|interface|interface:[address]|address} Packet Destination. Format same as SOURCE column. PROTOCOL (proto) - {-|any|all|protocol-name|protocol-number|ipp2p[:{udp|all}]} A protocol-name (from protocols(5)), a protocol-number, ipp2p, ipp2p:udp or ipp2p:all DEST PORT(S) (dport) - {-|any|all|ipp2p-option|port-name-or-number[,port-name-or-number]...} Destination Port number. Service name from services(5) or port number. May only be specified if the protocol is TCP (6), UDP (17), DCCP (33), SCTP (132) or UDPLITE (136). You may place a comma-separated list of port names or numbers in this column if your kernel and ip6tables include multiport match support. If the PROTOCOL is ipp2p then this column must contain an ipp2p-option ("ip6tables -m ipp2p --help") without the leading "--". If no option is given in this column, ipp2p is assumed. SOURCE PORT(S) (sport) - {-|any|all|port-name-or-number[,port-name-or-number]...} Service name from services(5) or port number. May only be specified if the protocol is TCP (6), UDP (17), DCCP (33), SCTP (132) or UDPLITE (136). You may place a comma-separated list of port numbers in this column if your kernel and ip6tables include multiport match support. USER/GROUP (user) - [!][user-name-or-number][:group-name-or-number][+program-name] This column may only be non-empty if the CHAIN is OUTPUT. When this column is non-empty, the rule applies only if the program generating the output is running under the effective user and/or group specified (or is NOT running under that id if "!" is given). Examples: joe program must be run by joe :kids program must be run by a member of the 'kids' group !:kids program must not be run by a member of the 'kids' group +upnpd #program named upnpd The ability to specify a program name was removed from Netfilter in kernel version 2.6.14. MARK - [!]value[/mask][:C] Defines a test on the existing packet or connection mark. The rule will match only if the test returns true. If you don't want to define a test but need to specify anything in the following columns, place a "-" in this field. ! Inverts the test (not equal) value Value of the packet or connection mark. mask A mask to be applied to the mark before testing. :C Designates a connection mark. If omitted, the packet mark's value is tested. IPSEC - option-list (Optional - Added in Shorewall 4.4.13 ) The option-list consists of a comma-separated list of options from the following list. Only packets that will be encrypted or have been de-crypted via an SA that matches these options will have their source address changed. reqid=number where number is specified using setkey(8) using the 'unique:number option for the SPD level. spi=<number> where number is the SPI of the SA used to encrypt/decrypt packets. proto=ah|esp|ipcomp IPSEC Encapsulation Protocol mss=number sets the MSS field in TCP packets mode=transport|tunnel IPSEC mode tunnel-src=address[/mask] only available with mode=tunnel tunnel-dst=address[/mask] only available with mode=tunnel strict Means that packets must match all rules. next Separates rules; can only be used with strict yes or ipsec When used by itself, causes all traffic that will be encrypted/encapsulated or has been decrypted/un-encapsulted to match the rule. no or none When used by itself, causes all traffic that will not be encrypted/encapsulated or has been decrypted/un-encapsulted to match the rule. If this column is non-empty, then: A chain NAME may appearing in the ACTION column must be a chain branched either directly or indirectly from the accountin or accountout chain. The CHAIN column must contain either accountin or accountout or a chain branched either directly or indirectly from those chains. These rules will NOT appear in the accounting chain. HEADERS - [!][any:|exactly:]header-list (Optional - Added in Shorewall 4.4.15) The header-list consists of a comma-separated list of headers from the following list. auth, ah, or 51 Authentication Headers extension header. esp, or 50 Encrypted Security Payload extension header. hop, hop-by-hop or 0 Hop-by-hop options extension header. route, ipv6-route or 41 IPv6 Route extension header. frag, ipv6-frag or 44 IPv6 fragmentation extension header. none, ipv6-nonxt or 59 No next header proto, protocol or 255 Any protocol header. If any: is specified, the rule will match if any of the listed headers are present. If exactly: is specified, the will match packets that exactly include all specified headers. If neither is given, any: is assumed. If ! is entered, the rule will match those packets which would not be matched when ! is omitted. In all of the above columns except ACTION and CHAIN, the values -, any and all may be used as wildcards. Omitted trailing columns are also treated as wildcards. /etc/shorewall6/accounting http://shorewall.net/Accounting.html http://shorewall.net/shorewall_logging.html http://shorewall.net/configuration_file_basics.htm#Pairs shorewall6(8), shorewall6-actions(5), shorewall6-blacklist(5), shorewall6-hosts(5), shorewall6-interfaces(5), shorewall6-maclist(5), shoewall6-netmap(5),shorewall6-params(5), shorewall6-policy(5), shorewall6-providers(5), shorewall6-route_rules(5), shorewall6-routestopped(5), shorewall6-rules(5), shorewall6.conf(5), shorewall6-secmarks(5), shorewall6-tcclasses(5), shorewall6-tcdevices(5), shorewall6-tcrules(5), shorewall6-tos(5), shorewall6-tunnels(5), shorewall6-zones(5)
