============================================================================Supported Interface Informationas of version 2.6, March 2002----------------------------------------------------------------------------IPTraf has been slowly improving with its interface support since itsfirst release.  IPTraf currently supports the following types of links:Local loopbackEthernet (10 and 100 Mbps)SLIP and variantsAsynchronous PPP over analog telephone linesSynchronous PPP over digital ISDN linesISDN using raw IP encapsulationISDN using Cisco-HDLC encapsulationFDDI (now includes Ethernet-emulating interfces)Frame Relay FRAD/DLCI interfaces (new as of IPTraf 2.5.0)PLIP (Parallel Line IP)Token RingDVB satellite-receive interfacesSBNI long-range modem interfacesWireless LAN interfacesFree s/WAN logical interfacesADDITIONAL INTERFACE SUPPORTAs much as I would like to support every concievable interface inexistence, we know that's just not possible.  I myself do not have a lotof interface types.  However, that does not mean I'm unwilling to supportmore.So here's the deal.  If you'd like me to include support for a new type ofinterface I will need this information as much as possible:* Resulting link type in spkt_family after a recvfrom() on a (PF_PACKET,  SOCK_RAW) socket (ARPHRD_ETHER, ARPHRD_PPP, etc).* Standard interface name for the type of network medium (eth0, eth1,  ppp0, etc) after the recvfrom() mentioned above.* Packet structure.  How many bytes are there in its data-link header  (with Ethernet, there are 14, with FDDI, 21) as returned by recvfrom on  a (PF_PACKET, SOCK_RAW) socket?* Pointers to other sources of information if possible.  This is necessary  for cases like ISDN, which claim to be ARPHRD_ETHER, but have completely  different frame structures, so I needed the appropriate ioctl()  information.  Token Ring packets may have a RIF structure or not.  These  factors need to be taken into consideration.Then finally, if you come up with a request for support for a newinterface, I'd really like an offer to have it tested, obviously, since Ido not have the interface myself (for example, my country is primarilyleased-line territory, and ISDN is only starting, and it isn't even in mycity yet).  If I do not receive an offer to test, then support cannot beincluded.Patches, even quick-and-dirty ones, are very much welcome.All information and patches will be fully credited in the CHANGES file.Looking forward to serving you.-- Gerard <riker@seul.org>
