PPP and Red Pitaya
Posted: Mon Mar 05, 2018 9:28 pm
I need to conect to the RP via a radio transmitter which has an UART interface and use ssh. So basically I need to communicate with the RP using ssh via the UART port. To that end there is the ppp protocol. A ppp daemon is running on the RP and the host side. Once they have done their handshake one can use ssh, scp ping etc.. This is how it should be.
Now, ppp on the host PC (Ubuntu) works, the ppp deamon is running, no problem. But, I cannot get it to work on the RP side, as upon starting the ppp daemon on the RP it "cannot find the /dev/ppp" node, even though I created it and set permissions to 600. The second error message is "please load ppp_generic kernel module". To solve this I already put "alias char-major-108 ppp_generic" into the /etc/modprobe.d/modules.conf. I also created a /etc/modules.conf just in case it is looking there for the module.
Has anyone have had this issue and solved it? Thanks!
