>Environment:
/etc/gettytab entry:
dial.115200:\
:np:to#30:sp#115200:pp=/usr/sbin/pppd
>Description:
With the timeout option enabled in a gettytab entry (:to#30:) and pppd
invoked when getty automatically detects a ppp header, pppd dies with
SIGALRM when the timeout occurrs.
>How-To-Repeat:
Add the ':to#30:' option to a getty dialup config. Set the 'pp' option to
automatically start pppd when getty detects a ppp frame. Pppd will then
die when getty should have died due to a timeout.
>Fix:
Apply the following patch to main.c of the getty source. This patch is
relative to -current as of May 31, 1997.
