PPTP (Poptop)

(Poptop) pptpd Server Setup

Here's what I did to get Poptop pptpd (1.3.4) running on my Slackware (13.37) box.

1) Install the official Slackware ppp package using pkgtool or slackpkg. 2) Install the ppptpd package from Slackbuilds.org using sbopkg.	***NOTE: The package name is NOT Poptop, it's pptpd*** 3) Edit /etc/pptpd.conf	ADD:	localip 10.7.0.1	remoteip 10.7.0.2-50	CHANGE:	option /etc/ppp/options.pptpd -> option /etc/ppp/options 4) Edit /etc/ppp/options	HERE IS A GOTCHA- The official Slackware ppp package (at the time of this writing) contains an error in the options	file. The pppd binary was compiled to look for the new ms-dns parameter but the option file has the old dns-addr	parameter.	CHANGE:	# dns-addr 192.168.1.1 -> ms-dns 8.8.8.8 (or whatever your dns server is) 5) Edit the /etc/ppp/chap-secrets file.	For some reason, the default Slackware package has 4 example entries in it that are not commented (jacco,*,sam,*)	delete these. You don't want jacco or sam to have a free connection into your box...	ADD: one entry for each user you want to allow access.	Format is: CLIENT [tab] SERVER [tab] PASSWORD [tab] IP ADDRESS	Mine looks like this:	bob	*	"BobsPasswordIsStrong"	*	sue	*	"FluffyBunnies92"	* 6) Finally to start pptpd, normally you would just execute 'pptpd &' but being that I'm a good Slacker, I wrote an rc.pptpd script.	Create /etc/rc.d/rc.pptpd	contents:	#!/bin/sh	#	# /etc/rc.d/rc.pptpd	#	# Start/stop/restart the pptpd server.	#	# To make PopTop start automatically at boot, make this	# file executable: chmod 755 /etc/rc.d/rc.pptpd	#	pptpd_start() { if [ -x /usr/sbin/pptpd ]; then echo "Starting PopTop pptpd: /usr/sbin/pptpd server.conf" /usr/sbin/pptpd & fi	}	pptpd_stop() { killall pptpd	}	pptpd_restart() { pptpd_stop sleep 2 pptpd_start	}	case "$1" in	'start') pptpd_start  ;;	'stop') pptpd_stop  ;;	'restart') pptpd_restart  ;;	*) # Default is "start", for backwards compatibility with previous # Slackware versions. This may change to a 'usage' error someday. pptpd_start	esac 7) Make it executable (and autobootable on start up)	chmod 755 /etc/rc.d/rc.pptpd To start it manually- /etc/rc.d/rc.pptpd start To be useful you next need to configure your firewall to forward and masquerade traffic from the vpn out to the world... 8) Edit/create: /etc/rc.d/rc.firewall	ADD:	iptables -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT	iptables -A FORWARD -i ppp+ -j ACCEPT	iptables -A FORWARD -o ppp+ -j ACCEPT	iptables -A FORWARD -j ACCEPT	iptables -t nat -A POSTROUTING -s 10.7.0.0/24 -o ppp+ -j MASQUERADE 9) Make it executable	chmod 755 /etc/rc.d/rc.firewall 10) Flush the old firewall rules (forgetting to do this caused me all sorts of grief (Thanks mancha))	iptables -F 11) Execute the new firewall rules	/etc/rc.d/rc.firewall If you and I haven't made any mistakes, you should now have pptp (server) and router working on your box.
