I have managed to establish a connection from my Mac (OS X 10.9) to Raspberry Pi (Raspbian 3.6.11) using a serial USB to TTL cable by following these instructions.
I can successfully establish a serial connection to the Pi using
screen, and operate the Pi normally.
I would now like to transfer files from my Mac to the Pi over this cable using PPP. I have tried following the instructions on this page, specifically:
On the Pi:
sudo pppd noauth
I had to specify
noauth to avoid the error:
pppd: The remote system is required to authenticate itself pppd: but I couldn't find any suitable secret (password) for it to use to do so.
Then in the Mac Terminal:
sudo pppd -detach noauth proxyarp /dev/tty.usbserial-FTGCC2MV 115200 10.0.0.1:10.0.0.2 passive local maxfail 0 nocrtscts xonxoff
This gives me the error:
Wed Oct 30 13:26:56 2013 : publish_entry SCDSet() failed: Success! Wed Oct 30 13:26:56 2013 : publish_entry SCDSet() failed: Success! Wed Oct 30 13:26:56 2013 : Using interface ppp0 Wed Oct 30 13:26:56 2013 : Connect: ppp0 <--> /dev/tty.PL2303-000012FD Wed Oct 30 13:27:26 2013 : LCP: timeout sending Config-Requests
If I enable
debug on the client side I get:
Wed Oct 30 13:26:31 2013 : sent [LCP ConfReq id=0x1 <asyncmap 0xa0000> <magic 0x79e49366> <pcomp> <accomp>]
So it seems like an
LCP ConfReq is being sent to the Pi but no response is received.
How can I resolve this issue?
