Mpd (3.x) & mpd4 config and differeces in reconnect/dial behaviour ?

[Alan Tamm]

Hi everyone!

Since upgrade from 3.x to 4.x I have to manually (re) open the bundle PPPoE
but I can't afford this system to be offline/needing manual intervention
from now on. When the connection times out mpd4 just won't reconnect..


This (mpd3.x) setup works flawlessly (without reconnection problems):

#mpd.conf
pppoe:
new -i ng0 pppoe PPPoE
set iface addrs 192.168.0.1 192.168.0.2
set iface route default
set iface disable on-demand
set iface idle 0
set bundle disable multilink
set bundle authname "secret"
set link no acfcomp protocomp
set link disable pap chap
set link accept chap
set link mtu 1492
set link keep-alive 10 60
set ipcp yes vjcomp
set ipcp ranges 0.0.0.0/0 0.0.0.0/0
open iface

#mpd.links
PPPoE:
set link type pppoe
set pppoe iface rl0
set pppoe service ""
set pppoe disable incoming
set pppoe enable originate


## mpd4 --version
## Version 4.3
# (no reconnect)

#mpd.conf

PPPoE:
# new PPPoE PPPoE
new -i ng0 PPPoE PPPoE
set iface route default
set iface disable on-demand
set iface idle 0
set ipcp yes vjcomp
set ipcp ranges 0.0.0.0/0 0.0.0.0/0
set bundle disable multilink
## set bundle disable noretry
set auth authname "secret"
set link no acfcomp protocomp
set link disable pap chap chap-msv1 chap-msv2 eap
set link accept chap-md5 chap
set link keep-alive 5 30
set link max-redial 0
open

#mpd.links
PPPoE:
set phys type pppoe
set pppoe iface rl0
# set pppoe service "whatever"
set pppoe disable incoming
set pppoe enable originate

Thats it (the problem), after timeout no retry attempt is made !

# quick fix:
Manual open command for bundle PPPoE

# and log output after open:

I have made some attempts before but had no time to go in depth until now..
Settings I played with so far  although without any progress whatsoever are:

set bundle disable noretry    # dumped - no effect
set link max-redial 0            # default is -1 and 0 - redial indefinitely


I'm kind of lost right now so any help would be appreciated..
And I do like mpd 4.x new features (ipv6cp etc) A LOT btw ;)
