pptpd - PPTP VPN daemon
pptpd [ options ]
pptpd is the Poptop PPTP daemon, which manages tunnelled PPP
connections encapsulated in GRE using the PPTP VPN protocol. It may
contain features like IP address management and TCP wrappers if

Corresponds to the connections option in pptpd.conf. If pptpd
is allocating IP addresses (e.g. --delegate is not used) then
the number of connections is also limited by the remoteip option
delegates the allocation of client IP addresses to pppd(8).
Without this option, which is the default, pptpd manages the
list of IP addresses for clients and passes the next free
address to pppd. With this option, pptpd does not pass an
address, and so pppd may use radius or chap-secrets to allocate

To turn on debugging, add 'debug' to /etc/pptpd.conf and your PPP
options file, and restart pptpd.
Typically the PPP options file is options.pptpd in /etc/ppp, though on
some distributions it may be pptpd-options. Use your package manager
to find it, e.g. 'rpm -ql pptpd | grep options' or 'dpkg --listfiles
pptpd | grep options'.
You may need to configure syslogd to catch debug messages. e.g. edit
/etc/syslog.conf and add something similar to the example below, then
# debug logging
This will log all debug information, except mail, to the file
/var/log/debug. Note that this is a lot of information and might flood
your disks. If performance is an issue, you can try turning off sync
during your debugging, by prefixing the destination with '-'.
# debug logging
Disable this line and restart syslog after you are done debugging. See
the syslog man pages for more details.
