[Jolly Shah]

Hello All,


I am runnning rppppoe client with pppd daemon from my router. It
always gives below error either after PADR request or PADS request.
"pppoe: read (asyncReadFromPPP): Session 27: Input/output error"

below is excerpt from the debug log:

* The following section is a dump of the packets
* sent and received by rp-pppoe.  If you don't see
* any output, it's an Ethernet driver problem.  If you only
* see three PADI packets and nothing else, check your cables
* and modem.  Make sure the modem lights flash when you try
* to connect.  Check that your Ethernet card is in
* half-duplex, 10Mb/s mode.  If all else fails,
* try using pppoe-sniff.
