Sometimes when I boot a soekris box (net5501) - OpenBSD 4.3, I didn't get

each times an ip address for the pppoe0 link.

This is a problem as I can connect to this box only remotely.

I didn't find on the documentation how to reconnect automatically if the

link goes down.
Any ideas ?
Xavier.
Here is my configuration :
/etc/sysctl.conf file :
net.inet.ip.forwarding=1

net.inet6.ip6.forwarding=1
/etc/rc.conf.local file :
named_flags=""      # nameserver
ntpd_flags=""          # timeserver
dhcpd_flags=""       # DHCP server
ftpproxy_flags="" # ftp proxy server
pf=YES
pf_rules=/etc/pf.conf
check_quotas=NO  # desactivate quotas
/etc/resolv.conf file :
lookup file bind
nameserver 127.0.0.1
*/etc/hostname.pppoe0 file file :*
inet 0.0.0.0 255.255.255.255 0.0.0.1 pppoedev vr0 \
authproto pap authname my_USER authkey my_PASSWORD up
!/sbin/route add default 0.0.0.1
*/etc/hostname.**vr0 file :*
up
*

*
*/etc/hostname.**vr1 file :*
inet 10.0.0.1 255.255.255.0 NONE
I don't have /etc/mygate file.

I don't have /var/named/named.boot file

I use pf.

pppoe automagically reconnects.
many ISPs have some logic to deny you from opening two ppp sessions,

so by the time your box reboots the old sessions has not yet timed

out. You can't do all that much but waiting for the old session to

expire, pppoe will retry all the time.

Search for PPPOE_TERM_UNKNOWN_SESSIONS kernel option. I have such

provider, and this option helps a lot.
BTW: Is there any point to translate this knob to interface linkN flag?

The soekris box seems now working. I have to wait several days...

I just add in the file : /etc/rc.shutdown

ifconfig pppoe0 down
Thanks a lot all for your help.
I 'll have a look also for PPOE_TERM_UNKNOWN_SESSIONS
Regards.
Xavier.

Thanks a lot.

So if my ip change I still have to reload pf ? using ppp.linkdown ?
Xavier.

not if you write your pf.conf correctly

Do you think my pf.conf is correct ?

Just put "ifconfig pppoe0 down" in your rc.shutdown script and this

problem should be solved.

I wrote a short piece of code for rc.local, that was waiting for the pppoe

link to come up, before I discoverd that.
Kind regards,

   Markus

Hi Xavier,
Look at this file: ppp.linkdown.sample it will be in /etc/ppp/
