I have a FreeBSD server that's connected to WAN using PPPoE. Iva esuccessfully set ip the L2TP and PPTP VPN ontop of this PPPoE WAN connection. The problem is that L2TP needs to call 'set lt2p self ` clause to start listening to the udp/1701 port, so when the WAN PPPoE session is reestablished, I need to dynamically set up the L2TP config part. I'm using an expect script to do this, it connects to the mpd5 network console and loads the config part, and does it like this:
set timeout 2
spawn telnet localhost 5005
expect -re "Username: "
send myc00ll0g1nr
exp_continue -continue_timer
expect -re "Password: "
send myc00lpa$$r
exp_continue -continue_timer

It's fully working when I invoke it interactively via ssh. So I added it into the set iface up-script <expect wrapper> and the expect wrapper is calling it like expect -f myscript.exp. But when it does that on PPPoE connection reestablishing, I receive the following bunch of errors in the mpd.log:
Mar 21 17:42:23 ronin mpd[37412]: [wan] IFACE: Up event
Mar 21 17:42:23 ronin mpd[37412]: CONSOLE: Connect

Mar 21 17:42:23 ronin mpd[37412]: CONSOLE: Error while reading: Connection reset by peer
And this is definitely my expect script (because it does send right about 34 lines of commands). Why ? Why does it work when I invoke it by hand and when mpd5 invokes it - it does not ? Okay, I understand that when I invoke it it has a controlling terminal, and when mpd5 invokes it it does not, but does it matter ? How do I solve this ? Or is the root of the problem something else ?

what about raising the timeout or add a sleep? maybe mpd5 needs some time? please add an debug output to your script like: ``` log_file /tmp/mylog.txt ```
