The TZ +userspace environment variable specifies how the UTC-based system time is +displayed, e.g. when you run date(1), or what you see on your desktop clock. +The TZ string may resolve to different offsets at different dates, which is +what enables the automatic time-jumping in userspace. when DST changes. The +kernel's timezone offset variable is used when it has to convert between +non-UTC sources, such as FAT filesystems, to UTC (since the latter is what the +rest of the system uses). +.PP +The caveat with the kernel timezone is that Linux distributions may ignore to +set the kernel timezone, and instead only set the system time. Even if a +particular distribution does set the timezone at boot, it is usually does not +keep the kernel timezone offset - which is what changes on DST - up to date. +ntpd will not touch the kernel timezone, so running it will not resolve the +issue.

Several different tables -may be defined. Each table contains a number of built-in -chains and may also contain user-defined chains. -.PP -Each chain is a list of rules which can match a set of packets. Each -rule specifies what to do with a packet that matches. This is called -a `target', which may be a jump to a user-defined chain in the same -table. -.SH TARGETS -A firewall rule specifies criteria for a packet and a target. If the -packet does not match, the next rule in the chain is the examined; if -it does match, then the next rule is specified by the value of the -target, which can be the name of a user-defined chain or one of the -special values \fBACCEPT\fP, \fBDROP\fP, \fBQUEUE\fP or \fBRETURN\fP. -.PP -\fBACCEPT\fP means to let the packet through. -\fBDROP\fP means to drop the packet on the floor. -\fBQUEUE\fP means to pass the packet to userspace. -(How the packet can be received -by a userspace process differs by the particular queue handler. 2.4.x -and 2.6.x kernels up to 2.6.13 include the \fBip_queue\fP -queue handler. Kernels 2.6.14 and later additionally include the -\fBnfnetlink_queue\fP queue handler. Packets with a target of QUEUE will be -sent to queue number '0' in this case. Please also see the \fBNFQUEUE\fP -target as described later in this man page.) -\fBRETURN\fP means stop traversing this chain and resume at the next -rule in the -previous (calling) chain. If the end of a built-in chain is reached -or a rule in a built-in chain with target \fBRETURN\fP -is matched, the target specified by the chain policy determines the -fate of the packet. -.SH TABLES -There are currently three independent tables (which tables are present -at any time depends on the kernel configuration options and which -modules are present). -.TP -\fB\-t\fP, \fB\-\-table\fP \fItable\fP -This option specifies the packet matching table which the command -should operate on. If the kernel is configured with automatic module -loading, an attempt will be made to load the appropriate module for -that table if it is not already there. - -The tables are as follows: -.RS -.TP .4i -\fBfilter\fP: -This is the default table (if no \-t option is passed). It contains -the built-in chains \fBINPUT\fP (for packets destined to local sockets), -\fBFORWARD\fP (for packets being routed through the box), and -\fBOUTPUT\fP (for locally-generated packets). -.TP -\fBmangle\fP: -This table is used for specialized packet alteration. Until kernel -2.4.17 it had two built-in chains: \fBPREROUTING\fP -(for altering incoming packets before routing) and \fBOUTPUT\fP -(for altering locally-generated packets before routing). -Since kernel 2.4.18, three other built-in chains are also supported: -\fBINPUT\fP (for packets coming into the box itself), \fBFORWARD\fP -(for altering packets being routed through the box), and \fBPOSTROUTING\fP -(for altering packets as they are about to go out). -.TP -\fBraw\fP: -This table is used mainly for configuring exemptions from connection -tracking in combination with the NOTRACK target. It registers at the netfilter -hooks with higher priority and is thus called before ip_conntrack, or any other -IP tables. It provides the following built-in chains: \fBPREROUTING\fP -(for packets arriving via any network interface) \fBOUTPUT\fP -(for packets generated by local processes) -.RE -.SH OPTIONS -The options that are recognized by -\fBip6tables\fP can be divided into several different groups. -.SS COMMANDS -These options specify the specific 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 and option names, you -need to use only enough letters to ensure that -\fBip6tables\fP can differentiate it from all other options. -.TP -\fB\-A\fP, \fB\-\-append\fP \fIchain rule-specification\fP -Append one or more rules to the end of the selected chain. -When the source and/or destination names resolve to more than one -address, a rule will be added for each possible address combination. -.TP -\fB\-D\fP, \fB\-\-delete\fP \fIchain rule-specification\fP -.ns -.TP -\fB\-D\fP, \fB\-\-delete\fP \fIchain rulenum\fP -Delete one or more rules from the selected chain. There are two -versions of this command: the rule can be specified as a number in the -chain (starting at 1 for the first rule) or a rule to match. -.TP -\fB\-I\fP, \fB\-\-insert\fP \fIchain\fP [\fIrulenum\fP] \fIrule-specification\fP -Insert one or more rules in the selected chain as the given rule -number. So, if the rule number is 1, the rule or rules are inserted -at the head of the chain. This is also the default if no rule number -is specified. -.TP -\fB\-R\fP, \fB\-\-replace\fP \fIchain rulenum rule-specification\fP -Replace a rule in the selected chain. If the source and/or -destination names resolve to multiple addresses, the command will -fail. Rules are numbered starting at 1. -.TP -\fB\-L\fP, \fB\-\-list\fP [\fIchain\fP] -List all rules in the selected chain. If no chain is selected, all -chains are listed. Like every other ip6tables command, it applies to the -specified table (filter is the default). -.IP "" -Please note that it is often used with the \fB\-n\fP -option, in order to avoid long reverse DNS lookups. -It is legal to specify the \fB\-Z\fP -(zero) option as well, in which case the chain(s) will be atomically -listed and zeroed. The exact output is affected by the other -arguments given. The exact rules are suppressed until you use -.nf - ip6tables \-L \-v -.fi -.TP -\fB\-S\fP, \fB\-\-list\-rules\fP [\fIchain\fP] -Print all rules in the selected chain. If no chain is selected, all -chains are printed like ip6tables-save. Like every other ip6tables command, -it applies to the specified table (filter is the default). -.TP -\fB\-F\fP, \fB\-\-flush\fP [\fIchain\fP] -Flush the selected chain (all the chains in the table if none is given). -This is equivalent to deleting all the rules one by one. -.TP -\fB\-Z\fP, \fB\-\-zero\fP [\fIchain\fP [\fIrulenum\fP]] -Zero the packet and byte counters in all chains, or only the given chain, -or only the given rule in a chain. It is legal to -specify the -\fB\-L\fP, \fB\-\-list\fP -(list) option as well, to see the counters immediately before they are -cleared. (See above.) -.TP -\fB\-N\fP, \fB\-\-new\-chain\fP \fIchain\fP -Create a new user-defined chain by the given name. There must be no -target of that name already. -.TP -\fB\-X\fP, \fB\-\-delete\-chain\fP [\fIchain\fP] -Delete the optional user-defined chain specified. There must be no references -to the chain. If there are, you must delete or replace the referring rules -before the chain can be deleted. The chain must be empty, i.e. not contain -any rules. If no argument is given, it will attempt to delete every -non-builtin chain in the table. -.TP -\fB\-P\fP, \fB\-\-policy\fP \fIchain target\fP -Set the policy for the chain to the given target. See the section \fBTARGETS\fP -for the legal targets. Only built-in (non-user-defined) chains can have -policies, and neither built-in nor user-defined chains can be policy -targets. -.TP -\fB\-E\fP, \fB\-\-rename\-chain\fP \fIold\-chain new\-chain\fP -Rename the user specified chain to the user supplied name. This is -cosmetic, and has no effect on the structure of the table. -.TP -\fB\-A\fP, \fB\-\-append\fP \fIchain rule-specification\fP -Append one or more rules to the end of the selected chain. -When the source and/or destination names resolve to more than one -address, a rule will be added for each possible address combination. -.TP -\fB\-h\fP -Help. -Give a (currently very brief) description of the command syntax. -.SS PARAMETERS -The following parameters make up a rule specification (as used in the -add, delete, insert, replace and append commands). -.TP -[\fB!\fP] \fB\-p\fP, \fB\-\-protocol\fP \fIprotocol\fP -The protocol of the rule or of the packet to check. -The specified protocol can be one of \fBtcp\fP, \fBudp\fP, \fBudplite\fP, -\fBicmpv6\fP, \fBesp\fP, \fBmh\fP or \fBall\fP, -or it can be a numeric value, representing one of these protocols or a -different one. A protocol name from /etc/protocols is also allowed. -But IPv6 extension headers except \fBesp\fP are not allowed. -\fBesp\fP and \fBipv6\-nonext\fP -can be used with Kernel version 2.6.11 or later. -A "!" argument before the protocol inverts the -test. The number zero is equivalent to \fBall\fP. -Protocol \fBall\fP -will match with all protocols and is taken as default when this -option is omitted. -.TP -[\fB!\fP] \fB\-s\fP, \fB\-\-source\fP \fIaddress\fP[\fB/\fP\fImask\fP] -Source specification. -\fIAddress\fP can be either be a hostname, -a network IP address (with \fB/\fP\fImask\fP), or a plain IP address. -Names will be resolved once only, before the rule is submitted to the kernel. -Please note that specifying any name to be resolved with a remote query such as -DNS is a really bad idea. -(Resolving network names is not supported at this time.) -The \fImask\fP is a plain number, -specifying the number of 1's at the left side of the network mask. -A "!" argument before the address specification inverts the sense of -the address. The flag \fB\-\-src\fP -is an alias for this option. -Multiple addresses can be specified, but this will \fBexpand to multiple -rules\fP (when adding with \-A), or will cause multiple rules to be -deleted (with \-D). -.TP -[\fB!\fP] \fB\-d\fP, \fB\-\-destination\fP \fIaddress\fP[\fB/\fP\fImask\fP] -Destination specification. -See the description of the \fB\-s\fP -(source) flag for a detailed description of the syntax. The flag -\fB\-\-dst\fP is an alias for this option. -.TP -\fB\-j\fP, \fB\-\-jump\fP \fItarget\fP -This specifies the target of the rule; i.e., what to do if the packet -matches it. The target can be a user-defined chain (other than the -one this rule is in), one of the special builtin targets which decide -the fate of the packet immediately, or an extension (see \fBEXTENSIONS\fP -below). If this -option is omitted in a rule (and \fB\-g\fP -is not used), then matching the rule will have no -effect on the packet's fate, but the counters on the rule will be -incremented. -.TP -\fB\-g\fP, \fB\-\-goto\fP \fIchain\fP -This specifies that the processing should continue in a user -specified chain. Unlike the \-\-jump option return will not continue -processing in this chain but instead in the chain that called us via -\-\-jump. -.TP -[\fB!\fP] \fB\-i\fP, \fB\-\-in\-interface\fP \fIname\fP -Name of an interface via which a packet was received (only for -packets entering the \fBINPUT\fP, \fBFORWARD\fP and \fBPREROUTING\fP -chains). When the "!" argument is used before the interface name, the -sense is inverted. If the interface name ends in a "+", then any -interface which begins with this name will match. If this option is -omitted, any interface name will match. -.TP -[\fB!\fP] \fB\-o\fP, \fB\-\-out\-interface\fP \fIname\fP -Name of an interface via which a packet is going to be sent (for packets -entering the \fBFORWARD\fP, \fBOUTPUT\fP and \fBPOSTROUTING\fP -chains). When the "!" argument is used before the interface name, the -sense is inverted. If the interface name ends in a "+", then any -interface which begins with this name will match. If this option is -omitted, any interface name will match. -.\" Currently not supported (header-based) -.\" .TP -.\" [\fB!\fP] \fB\-f\fP, \fB\-\-fragment\fP -.\" This means that the rule only refers to second and further fragments -.\" of fragmented packets. Since there is no way to tell the source or -.\" destination ports of such a packet (or ICMP type), such a packet will -.\" not match any rules which specify them. When the "!" argument -.\" precedes the "\-f" flag, the rule will only match head fragments, or -.\" unfragmented packets. -.TP -\fB\-c\fP, \fB\-\-set\-counters\fP \fIpackets bytes\fP -This enables the administrator to initialize the packet and byte -counters of a rule (during \fBINSERT\fP, \fBAPPEND\fP, \fBREPLACE\fP -operations). -.SS "OTHER OPTIONS" -The following additional options can be specified: -.TP -\fB\-v\fP, \fB\-\-verbose\fP -Verbose output. This option makes the list command show the interface -name, the rule options (if any), and the TOS masks. The packet and -byte counters are also listed, with the suffix 'K', 'M' or 'G' for -1000, 1,000,000 and 1,000,000,000 multipliers respectively (but see -the \fB\-x\fP flag to change this). -For appending, insertion, deletion and replacement, this causes -detailed information on the rule or rules to be printed. -.TP -\fB\-n\fP, \fB\-\-numeric\fP -Numeric output. -IP addresses and port numbers will be printed in numeric format. -By default, the program will try to display them as host names, -network names, or services (whenever applicable). -.TP -\fB\-x\fP, \fB\-\-exact\fP -Expand numbers. -Display the exact value of the packet and byte counters, -instead of only the rounded number in K's (multiples of 1000) -M's (multiples of 1000K) or G's (multiples of 1000M). This option is -only relevant for the \fB\-L\fP command. -.TP -\fB\-\-line\-numbers\fP -When listing rules, add line numbers to the beginning of each rule, -corresponding to that rule's position in the chain. -.TP -\fB\-\-modprobe=\fP\fIcommand\fP -When adding or inserting rules into a chain, use \fIcommand\fP -to load any necessary modules (targets, match extensions, etc). -.SH MATCH EXTENSIONS -ip6tables can use extended packet matching modules. These are loaded -in two ways: implicitly, when \fB\-p\fP or \fB\-\-protocol\fP -is specified, or with the \fB\-m\fP or \fB\-\-match\fP -options, followed by the matching module name; after these, various -extra command line options become available, depending on the specific -module. You can specify multiple extended match modules in one line, -and you can use the \fB\-h\fP or \fB\-\-help\fP -options after the module has been specified to receive help specific -to that module. -.PP -The following are included in the base package, and most of these can -be preceded by a "\fB!\fP" to invert the sense of the match. -.\" @MATCH@ -.SH TARGET EXTENSIONS -ip6tables can use extended target modules: the following are included -in the standard distribution. -.\" @TARGET@ -.SH DIAGNOSTICS -Various error messages are printed to standard error. The exit code -is 0 for correct functioning. Errors which appear to be caused by -invalid or abused command line parameters cause an exit code of 2, and -other errors cause an exit code of 1. -.SH BUGS -Bugs? What's this? ;-) -Well... the counters are not reliable on sparc64. -.SH COMPATIBILITY WITH IPCHAINS -This \fBip6tables\fP -is very similar to ipchains by Rusty Russell. The main difference is -that the chains \fBINPUT\fP and \fBOUTPUT\fP -are only traversed for packets coming into the local host and -originating from the local host respectively. Hence every packet only -passes through one of the three chains (except loopback traffic, which -involves both INPUT and OUTPUT chains); previously a forwarded packet -would pass through all three. -.PP -The other main difference is that \fB\-i\fP refers to the input interface; -\fB\-o\fP refers to the output interface, and both are available for packets -entering the \fBFORWARD\fP chain. -There are several other changes in ip6tables. -.SH SEE ALSO -\fBip6tables\-save\fP(8), -\fBip6tables\-restore\fP(8), -\fBiptables\fP(8), -\fBiptables\-save\fP(8), -\fBiptables\-restore\fP(8), -\fBlibipq\fP(3). -.PP -The packet-filtering-HOWTO details iptables usage for -packet filtering, -the netfilter-extensions-HOWTO details the extensions that are -not in the standard distribution, -and the netfilter-hacking-HOWTO details the netfilter internals. -.br -See -.BR "http://www.netfilter.org/" . -.SH AUTHORS -Rusty Russell wrote iptables, in early consultation with Michael -Neuling. -.PP -Marc Boucher made Rusty abandon ipnatctl by lobbying for a generic packet -selection framework in iptables, then wrote the mangle table, the owner match, -the mark stuff, and ran around doing cool stuff everywhere. -.PP -James Morris wrote the TOS target, and tos match. -.PP -Jozsef Kadlecsik wrote the REJECT target. -.PP -Harald Welte wrote the ULOG and NFQUEUE target, the new libiptc, as well as TTL match+target and libipulog. -.PP -The Netfilter Core Team is: Marc Boucher, Martin Josefsson, Yasuyuki Kozakai, -Jozsef Kadlecsik, Patrick McHardy, James Morris, Pablo Neira Ayuso, -Harald Welte and Rusty Russell. -.PP -ip6tables man page created by Andras Kis-Szabo, based on -iptables man page written by Herve Eychenne <rv@wallfire.org>. -.\" .. and did I mention that we are incredibly cool people? -.\" .. sexy, too .. -.\" .. witty, charming, powerful .. -.\" .. and most of all, modest .. diff --git a/iptables-multi.c b/iptables-multi.c deleted file mode 100644 index 4dcc26d..0000000 --- a/iptables-multi.c +++ /dev/null @@ -1,50 +0,0 @@ -#include <stdio.h> -#include <stdlib.h> -#include <string.h> -#include <libgen.h> - -int iptables_main(int argc, char **argv);
