how to install poptop pptp server (beta)
apt-get install ppp
apt-get install pptpd vim /etc/pptpd.conf ################################################################################ # # Sample PoPToP configuration file # # for PoPToP version 1.0.0 # ################################################################################ # TAG: speed # # Specifies the speed for the PPP daemon to talk at. # Some PPP daemons will ignore this value. # speed 1152000000 # TAG: option # # Specifies the location of the PPP options file. # By default PPP looks in '/etc/ppp/options' # #option /this/is/the/options/file option /etc/ppp/options.ppp0 # TAG: debug # # Turns on (more) debugging to syslog. # debug # TAG: localip # TAG: remoteip # # Specifies the local and remote IP address ranges. # # You can specify single IP addresses seperated by commas or you can # specify ranges, or both. For example: # # 192.168.0.234,192.168.0.245-249,192.168.0.254 # # IMPORTANT RESTRICTIONS: # # 1. No spaces are permitted between commas or within addresses. # # 2. If you give more IP addresses than MAX_CONNECTIONS, it will # start at the beginning of the list and go until it gets # MAX_CONNECTIONS IPs. Others will be ignored. # # 3. No shortcuts in ranges! ie. 234-8 does not mean 234 to 238, # you must type 234-238 if you mean this. # # 4. If you give a single localIP, that's ok - all local IPs will # be set to the given one. You MUST still give at least one remote # IP for each simultaneous client. # #localip 192.168.0.234-238,192.168.0.245 #remoteip 192.168.1.234-238,192.168.1.245 localip 192.168.0.1 # eth0 public ip address #remoteip 192.168.1.100-199 remoteip 192.168.0.100 # eth1 public ip address will be given to remote # TAG: ipxnets # # This gives the range of IPX networks to allocate to clients. By # default IPX network number allocation is not handled internally. # By putting a low and high network number here a pool of IPX networks # can be defined. If this is done then there must be one IPX network # per client. # # The format is a pair of hex numbers without any 0x prefix separated # by a hyphen. # #ipxnets 00001000-00001FFF # TAG: listen # # Defines the IP address of the local interface on which pptpd # should listen for connections. The default is to listen on all # local interfaces (even ones brought up by pptp connections, thus # permitting pptp tunnels inside the pptp tunnels). # #listen 192.168.0.1 # TAG: pidfile # # This defines the file name in which pptpd should store its process # ID (or pid).
