Bug 115769 – pppd network configuration module does not allow a pty instead of a tty to be specified.

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description benjrh 2005-12-16 06:28:39 UTC]

I use ppp over pptp (over ethernet) for the connection to my isp. Normal pppd
configuration for this requires the pty option instead of a ttyname, i.e. the
pppd option: pty "/usr/sbin/pptp <host> --nolaunchpppd". I've tried setting up
net.ppp0 with baselayout-1.12.0_pre11-r3, but the pppd module insists on a
link_ppp0 option being specified, although I need to be able to omit it
entirely, and rely just on the pty option passed in pppd_ppp0. Or perhaps there
should be special pty or pptp parameters.

Reproducible: Always

link_ppp0="/dev/null" does not solve the problem?

You could always do:

link_ppp0="pty 'pptp 10.0.0.138 --nolaunchpppd'"

But it won't set the default route. Is there a way of doing this within the basic funtionality? It was possible in the old baselayout..

This works. Thanks. It's really a workaround though, since "pty" is a pppd option.

I pass "defaultroute" as a pppd option, to make pppd do the routing set-up. I also needed config_ppp0=( "ppp" ), which doesn't seem to be documented in net.examples, by the way.

sure... you could add "defaultroute" to pppd_ppp0 or do the following:
modules=( "iproute2" )
routes_ppp0=( "default" )

I disagree. It is true that pty is an option, but it also set the link over which the PPP connection is established. It makes sense to me, therefore I will recommend this link_${iface} variant in net.example.
