ppp demand mode does not work
Last modified: 2014-03-19 07:09:11 EDT
when starting pppd with the demand option, it will d demand dailing once.
After that call hangs up, it will NOT call again. I am using the same
scripts to run pppd in demand mode as I did in RH5.2 (had to recompile pppd
under 5.2). I am starting ppp from my own scripts vice setting it in the
/etc/sysconfig files. Of other note, restarting the networking with
/etc/rc.d/init.d/network restart causes pppd, if running, to dial even if
there is no traffic bound for that interface. The ../netwrork restart
never touches the ppp0 interface (doesn't see it in the $interfaces_boot

[Re: more successes in bug #6982]
PPP's demand-dialing creates two sets of PPP interfaces. The first is a loop
on your workstation that waits for outgoing traffic. Once outbound traffic
shows up, PPP establishes the link with the second pair. If your clients (or
your own workstation) even attempt to do a nameserver lookup, the link will go
up. This can happen even when software tries to lookup the name for the address
of the local PPP interface that you're supplying to it.
Closing due to old age.
