I have a rooted device with busybox, mtpd, and pppd. When I go through the settings menu to start the VPN the interface that is created is
ppp0. An application I want to use checks
/sys/client/net/ppp0/ifindex. If it exists the app shuts down.
The solution is to create the interface with another name. I can not figure out how to start a
pppd (with CHAP secretes) via the command line. I have tried the following:
cat /proc/PID/cmdline to see if I can figure out the passed arguments, but I can't.
NOTE: I do not have any
/etc/ppp/chap-secretes or options files. I only have a
/etc/ppp/ip-vpn-up which is a binary.
