Whew, what a journey down source code lane...
One thing that was killing my effort was that the debug statements in
the source code were using printf's, so the fact that, by default, pppd
spins itself off into the background means that one would never see the
printf's at all!
Wanting to find out how to keep it in the foreground I did a man on pppd
and "nodetach" came up, however it didn't work for me (wrong pppd).
Scanning the executable led me to a similar "-detach" which did.
In the end, getting this sort of debugging info needs to be done from
the *command line*. However the options (in dsl-provider, etc) will be
employed...
One note - the order of options in the command line, and file
dsl-provider, is important. It seems the options are scanned and the
lines parsed in order of appearance. This means that one cannot employ
an option /that is intended for a plug-in [e.g. rp-pppoe.so]/ until
*after* the plugin has been declared.
So to get my access concentrator's name I issue (yes, while ppp is
running in the background with a live connection):
pppd -detach plugin /usr/lib/pppd/rp-pppoe.so rp_pppoe_verbose 1 call
dsl-provider eth0
and I get this sort of info:
Plugin /usr/lib/pppd/rp-pppoe.so loaded.
RP-PPPoE plugin version 3.3 compiled against pppd 2.4.2
Plugin /usr/lib/pppd/rp-pppoe.so loaded.
RP-PPPoE plugin version 3.3 compiled against pppd 2.4.2

:: "-detach" tells is not to disappear into the background so that we
can the the printf() output
:: "plugin /usr/lib/pppd/rp-pppoe.so" tells pppd to first load the
plugin. The plug-in needs to be loaded or it will abend upon parsing any
plug-in-specific parameter/option
:: "rp_pppoe_verbose 1" tell the rp-pppoe.so plugin that we want the
verbose output
:: "call dsl-provider eth0" invokes our own DSL connection options.
Normally pppd is invoked from /usr/bin/pon, which is invoked by the
reference to ppp that appears in /etc/network/interfaces
Fun stuff: insert the option "dryrun" as the first parameter of the pppd
invocation and you'll get no actual ppp login but instead, an
enumeration of the options that are being employed. pppd draws,
variously, from /etc/ppp/options, /etc/ppp/peers/dsl-provider and the
command line). My list comes up with some repeated entries indicating
some sort of weirdness with the parsing of options.
Thanks one and all for LEAF!
