Hi Net@ people,
I posted this to hackers@ Mon, 11 Sep 2006 20:30:38 +0200 (CEST)
& got no response. I've fixed typos in subject & body.
Hopefuly net@ is more appropriate & can respond please :-)

I'm not clear if this is a bug or a config error:
It seems though my /usr/sbin/ppp was moving traffic
to & from internet, it was only listening for commands
(not data) on ipv6, not ipv4, thus I could not type commands
like dial & drop, unless instead of running ppp -auto
instead I invoked ppp manually in foreground on localhost.
Detail:
I have 2 alternate firewall/ gateways connected to world via DSL.
Each ran 4.10-Release OK. I raised one to 6.1-Release.
With a 6.1 Release custom kernel compiled with
options INET6
& /etc/ppp/ppp.conf with
set server +12345 mypasswd
sockstat -l showed only:
USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS
root ppp 1020 9 tcp6 *:12345 *:*
(& no 2nd line for ipv4), & so from my internal host, this failed:
pppctl -p mypasswd dsl:12345
& in fact even on my host named dsl, this failed
telnet localhost 12345
So I built a new kernel without INET6 & then sockstat -l showed
root ppp 972 9 tcp4 *:12345 *:*
& that works OK, I can finally manually control my PPP link up & down via
pppctl -p mypasswd dsl:12345
On my 4.10 host which has a kernel with both
options INET
options INET6
(as also has 4.10 GENERIC), that has always worked OK, & sockstat -l shows
root ppp 512 9 tcp46 *:12345 *:*
& pppctl -p mypasswd dsl:12345 works OK.
Questions:
- - Did I misconfigure something ?
- - Does ppp on 6.1 perhaps not now listen on ipv4 if INET6 is in kernel ?
(Unfortunate if so, as INET6 in in GENERIC kernel)
- - Should ppp have an extra flag added, forcing "Do listen on ipv4" ?
- - Is this a bug ? Should I file a send-pr ? Did I misconfig something ?
