rc.network glitch

[Andrew P.]

Hello!

I posted this problem earlier here, but I haven't got any response yet. 
I tried to debug it myself and here's where I stand:

The problem was that ppp does not start automatically at system startup, 
although all ppp_* variables are properly set in /etc/rc.conf. I tried 
to edit /etc/rc.network a little, adding a couple of echo's and a 
redirection.
====================================================
        case ${ppp_enable} in
        [Yy][Ee][Ss])
                ...
                su -m ${ppp_user} -c "exec ${ppp_command}" 2>&1 > 
/var/log/yesppp
                echo "Yes!!!" >> /var/log/yesppp
                echo ${ppp_command} >> /var/log/yesppp
                ;;
        esac
====================================================
So after I restarted the box, I have this yesppp file containing only 
two lines:
    Yes!!!
    /usr/sbin/ppp -quiet -ddial -nat mtu

I guess it should mean that everything's okay, but ppp has not been 
actually started! There's not even a record in /var/log/ppp.log. I tried 
to type by hand:
    su -m root -c "/usr/sbin/ppp -quiet -ddial -nat mtu"
and it starts okay. There's no error in dmesg, no kld's are loaded at 
startup, network is configured all right. Could anyone hint at how to 
debug such problems?

Best regards,
Andrew P.
