NAMEsrtconfig — configure srt interfaces
|srtconfig||srtX del N|
|srtconfig||srtX add srcaddr mask dstif dstaddr|
|srtconfig||srtX set N srcaddr mask dstif dstaddr|
DESCRIPTIONsrtconfig configures, or queries the configuration of, srt(4) interfaces. An srt(4) interface parcels packets out to other interfaces based on their source addresses (the normal routing mechanisms handle routing decisions based on destination addresses). An interface may have any number of routing choices; they are examined in order until one matching the packet is found. The packet is sent to the corresponding interface. (Any interface, even another srt interface, may be specified; if the configurations collaborate to cause a packet to loop forever, the system will lock up or crash.)
When run with only one argument, srtconfig prints the settings for the specified interface.
When run with two arguments, srtconfig prints the settings for the routing choice whose number is given as the second argument.
The form with ‘del’ deletes a routing choice, identified by its number. Other choices with higher numbers, if any, will be renumbered accordingly.
The ‘add’ form adds a choice; the other arguments describe it, and are documented below. The new choice is added at the end of the list.
The ‘set’ form replaces an existing choice, given its number. The other arguments describe the new choice which is to replace whatever currently exists at the given number N.
A choice is described by four pieces of information: a source address and mask, which are used to determine which choice an outgoing packet uses, a destination interface, and a destination address for the new interface. The source address and mask are specified like any Internet addresses (for convenience, the mask may instead be specified as a ‘/’ followed by a small integer, CIDR-style; note that in this case the mask must still be a separate argument; it cannot be appended to the end of the source address argument).
Each srt interface also has ordinary source and destination addresses which are set with ifconfig(8) like any other interface; these should not be confused with any of the above.
