What I mean is this: I have eth0 - eth3 on a machine, and a ppp

be deduced by running "ps" for the corresponding ppp daemon, and
inspecting the parameters; for example, with pppoe, I have "-I eth1"
parameter (-I stands for interface). But I want a more general
way which can be used in cases when we cannot get this info).
I would do this via an environment variable that you set via your start
script:
PPPOE_DEVICE=eth1 pppoe .... -I eth1
Have a look at daemontools or runit for mechanisms to give you good
reliable control of the execution environment of long-running processes.
