各位老大,我想使用 iptables 的时间参数来控制用户连接,使用 iptables -m time --help 出来以下内容
iptables -m time --help
iptables v1.4.6
Usage: iptables -[AD] chain rule-specification [options]
iptables -I chain [rulenum] rule-specification [options]
iptables -R chain rulenum rule-specification [options]
iptables -D chain rulenum [options]
iptables -[LS] [chain [rulenum]] [options]
iptables -[FZ] [chain] [options]
iptables -[NX] chain
iptables -E old-chain-name new-chain-name
iptables -P chain target [options]
iptables -h (print this help information)
Commands:
Either long or short options are allowed.
--append -A chain Append to chain
--delete -D chain Delete matching rule from chain
--delete -D chain rulenum
Delete rule rulenum (1 = first) from chain
--insert -I chain [rulenum]

--replace -R chain rulenum

--list -L [chain [rulenum]]
List the rules in a chain or all chains
--list-rules -S [chain [rulenum]]
Print the rules in a chain or all chains
--flush -F [chain] Delete all rules in chain or all chains
--zero -Z [chain [rulenum]]

--new -N chain Create a new user-defined chain
--delete-chain
-X [chain] Delete a user-defined chain
--policy -P chain target

--rename-chain
-E old-chain new-chain
Change chain name, (moving any references)
Options:
[!] --proto -p proto protocol: by number or name, eg. `tcp'
[!] --source -s address[/mask][...]
source specification
[!] --destination -d address[/mask][...]
destination specification
[!] --in-interface -i input name[+]
network interface name ([+] for wildcard)
--jump -j target
target for rule (may load target extension)
--goto -g chain
jump to chain with no return
--match -m match
extended match (may load extension)
--numeric -n numeric output of addresses and ports
[!] --out-interface -o output name[+]
network interface name ([+] for wildcard)
--table -t table table to manipulate (default: `filter')
--verbose -v verbose mode
--line-numbers print line numbers when listing
--exact -x expand numbers (display exact values)
[!] --fragment -f match second or further fragments only
--modprobe=<command> try to insert modules using this command
--set-counters PKTS BYTES set the counter during insert/append
[!] --version -V print package version.
time match options:
--datestart time Start and stop time, to be given in ISO 8601
--datestop time (YYYY[-MM[-DD[Thh[:mm[:ss]]]]])
--timestart time Start and stop daytime (hh:mm[:ss])
--timestop time (between 00:00:00 and 23:59:59)
[!] --monthdays value List of days on which to match, separated by comma
(Possible days: 1 to 31; defaults to all)
[!] --weekdays value List of weekdays on which to match, sep. by comma
(Possible days: Mon,Tue,Wed,Thu,Fri,Sat,Sun or 1 to 7
Defaults to all weekdays.)
--localtz/--utc Time is interpreted as UTC/local time
后来使用 /sbin/iptables -A FORWARD -p udp --dports 53 -m time --timestart 06:00 --timestop 18:00 --weekdays Sat,Sun -j ACCEPT
这条规则可以添加,没有报错,可是就是没办法匹配,不知道什么原因。
还有看了上面的 --help 里面有个 --localtz 后来添加到上面的规则中,也是不起作用,/sbin/iptables -A FORWARD -p udp --dports 53 -m time --localtz --timestart 06:00 --timestop 18:00 --weekdays Sat,Sun -j ACCEPT
还望各位老大指教指教。。。 |
