# pppd uses a lock file to lock the device that it has been. Write
# permisson to the directory where lock files are stored (/var/lock
# on Redhat systems) is required for pppd to work. On some systems
# pppd is not installed setuid root (as is done by default during the
# installation of pppd). On these systems pppd might fail to work
# because pppd can't create a lock file. This can be corrected by
# making pppd setuid root.
