Tomorrow I update baselayout and ppp packages (I remove previous /etc/init.d/net.ppp0 and /etc/conf.d/net.ppp0 files). I make link to net.lo with name 'net.ppp0'. I add to /etc/conf.d/net next lines: config_ppp0=( "ppp" ) link_ppp0="pty 'pptp --sync ppp.some-isp.ru --nolaunchpppd --loglevel 0'" username_ppp0='bsa' depend_ppp0() { need net.eth0 } pppd_ppp0=( lock sync require-mschap noauth nopcomp noaccomp nobsdcomp nodeflate defaultroute ) And I start net.ppp0. All starts and works fine. But I need some extra features: when real link is up it's need to add some routes, change some configs and reload some services (bind and postfix, for example). It is need for two separate internet channels. To check them I add to /etc/conf.d/net next functions: postup() { logger -t $1 Interface $1 up } postdown() { logger -t $1 Interface $1 down } Restart net.ppp0. And run 'killall pptp'... Next I run tail -f /var/log/messages: Aug 14 22:03:56 bsa pptp[19941]: anon log[ctrlp_disp:pptp_ctrl.c:738]: Received Start Control Connection Reply Aug 14 22:03:56 bsa pptp[19941]: anon log[ctrlp_disp:pptp_ctrl.c:772]: Client connection established.

Then I check /etc/ppp/ip-up script and found next lines: if [ -x /etc/init.d/net.$1 ]; then if ! /etc/init.d/net.$1 --quiet status ; then export IN_BACKGROUND="true" /etc/init.d/net.$1 --quiet start fi fi This can be read as: if /etc/init.d/net.ppp0 present and /etc/init.d/net.ppp0 not started then start it. But. As I know ip-up executed every time link up, but not pppd starts (for example, when isp cause link abort to change dynamic IP, and pppd automatically reconnects). In ip-down present same lines which stops script when it started. In this case: I kill pptp. pptp finishes and pppd execute ip-down and pptp again to restore link... at this time ip-down calls 'net.ppp0 stop' and pppd calls ip-up because link were up... ip-up calls 'net.ppp0 start' and pppd calls ip-down before terminating... etc...
