Cluster I/O Protocols (CIP) Configuration and Management Manual (H06.16+, J06.05+)
time
Matches the arrival time/date of packets.
--datestart YYYY[-MM[-DD[Thh[:mm[:ss]]]]]
--datestop MM[-DD[Thh[:mm[:ss]]]]]
--timestart hh:mm[:ss]
--timestop hh:mm[:ss]
[!] --monthdays day[,day...]
[!] --weekdays day[,day...]
--utc
Interprets the times given for --datestart, --datestop, --timestart and --timestop to be utc.
--localtz
Interprets the times given for --datestart, --datestop, --timestart and --timestop to be local kernel
time. (Default)
tos
Matches the 8 bits ToS (Type of Service) field in the IP header.
[!] --tos value[/mask]
[!] --tos symbol
u32
Tests whether quantities of up to 4 bytes extracted from a packet have specified values. The
specification of what to extract is general enough to find data at given offsets from tcp headers
or payloads.
[!] --u32 tests
The argument amounts to a program in a small language described below:
tests := location "=" value | tests "&&" location "=" value
value := range | value "," range
range := number | number ":" number
a single number, n, is interpreted the same as n:n. n:m is interpreted as the range of numbers
>=n and <=m.
location := number | location operator number
operator := "&" | "<<" | ">>" | "@"
The operators &, <<, >> and && mean the same as in C. The = is really a set membership
operator and the value syntax describes a set. The @ operator is what allows moving to the
next header.
udp
Matches UDP-specific values.
[!] --source-port | --sport port[:port]
[!] --destination-port | --dport port[:port]
Target Extensions ip6
The supported target extensions are based on the Linux ip6tables man pages. They are subject to
future changes made by Linux ip6tables implementation.
log
When the LOG target is set for a rule, the Linux kernel will print some information on all matching
packets (i.e., most IP header fields) to syslog. This is a "non-terminating target", i.e. rule traversal
continues at the next rule. So if you want to LOG the packets you refuse, use two separate rules
with the same matching criteria, first using target LOG, the next using DROP (or REJECT).
