SHOREWALL-TCPRI(5) | [FIXME: manual] | SHOREWALL-TCPRI(5) |
NAME¶
tcpri - Shorewall fileSYNOPSIS¶
/etc/shorewall/tcpri
DESCRIPTION¶
This file is used to specify the priority of traffic for simple traffic shaping (TC_ENABLED=Simple in shorewall.conf[1](5)). The priority band of each packet is determined by the last entry that the packet matches. If a packet doesn't match any entry in this file, then its priority will be determined by its TOS field. The default mapping is as follows but can be changed by setting the TC_PRIOMAP option in shorewall.conf[1](5).TOS Bits Means Linux Priority BAND ------------------------------------------------------------ 0x0 0 Normal Service 0 Best Effort 2 0x2 1 Minimize Monetary Cost 1 Filler 3 0x4 2 Maximize Reliability 0 Best Effort 2 0x6 3 mmc+mr 0 Best Effort 2 0x8 4 Maximize Throughput 2 Bulk 3 0xa 5 mmc+mt 2 Bulk 3 0xc 6 mr+mt 2 Bulk 3 0xe 7 mmc+mr+mt 2 Bulk 3 0x10 8 Minimize Delay 6 Interactive 1 0x12 9 mmc+md 6 Interactive 1 0x14 10 mr+md 6 Interactive 1 0x16 11 mmc+mr+md 6 Interactive 1 0x18 12 mt+md 4 Int.

Classifies matching traffic as High Priority
(1), Medium Priority (2) or Low Priority (3). For those interfaces listed in
shorewall-tcinterfaces[2](5), Priority 2 traffic will be deferred so
long and there is Priority 1 traffic queued and Priority 3 traffic will be
deferred so long as there is Priority 1 or Priority 2 traffic to send.
PROTO - protocol
Optional. The name or number of an IPv4
protocol.
PORT(S) - port [,...]
Optional. May only be given if the the PROTO
is TCP (6), UDP (17), DCCP (33), SCTP (132) or UDPLITE (136). A list of one or
more port numbers or service names from /etc/services. Port ranges of the form
lowport:highport may also be included.
ADDRESS - [ address]
Optional. The IP or MAC address that the
traffic originated from. MAC addresses must be given in Shorewall format. If
this column contains an address, then the PROTO, PORT(S) and INTERFACE column
must be empty ("-").
INTERFACE - [ interface]
Optional. The logical name of an
interface that traffic arrives from. If given, the PROTO, PORT(S) and
ADDRESS columns must be empty ("-").
Note
INTERFACE classification of packets occurs before classification by
PROTO/PORT(S)/ADDRESS. So it is highly recommended to place entries that
specify INTERFACE at the top of the file so that the rule about last entry
matches is preserved.
HELPER - [helper]
Optional. Names a Netfiler protocol helper
module such as ftp, sip, amanda, etc. A packet will match if it was accepted
by the named helper module. You can also append "-" and a port
number to the helper module name (e.g., ftp-21) to specify the port number
that the original connection was made on.
