  • Know Issues

There is a know issue with VPN PPTP service. When this problem occurs VPN PPTP users will be able to establish a VPN connection but will not be able to access any internal network resources.

The workaround for this problem, version 6.0 update 1, is the following procedure to be executed in the CLI as root:

  1. ps ax | grep pptp
  2. /etc/init.d/pptpd stop [stop the service]

- Identify the process Id number of pptpd that is still running and force it to stop with the command:

  1. kill -9 <pid number>
  2. /etc/init.d/pptpd start [start the service]

For example:

ipbrick:~# ps ax | grep pptp 4177 pts/4 S+ 0:00 grep pptp 15088 ? S 0:11 pptpd [89.152.241.114:FFE9 - 0F00] 15089 pts/0 Ss+ 0:00 /usr/sbin/pppd local file /etc/ppp/pptpd-options 115200 192.168.0.151:192.168.0.152 ipparam 89.152.241.114 remotenumber 89.152.241.114 20619 ? Ss 0:00 /usr/sbin/pptpd

ipbrick:~#

ipbrick:~# /etc/init.d/pptpd stop Stopping PPTP: pptpd.

ipbrick:~#

ipbrick:~# ps ax | grep pptp 4188 pts/4 S+ 0:00 grep pptp 15088 ? S 0:11 pptpd [89.152.241.114:FFE9 - 0F00] 15089 pts/0 Ss+ 0:00 /usr/sbin/pppd local file /etc/ppp/pptpd-options 115200 192.168.0.151:192.168.0.152 ipparam 89.152.241.114 remotenumber 89.152.241.114

ipbrick:~#

ipbrick:~# kill -9 15088

ipbrick:~# ps ax | grep pptp

4235 pts/4    S+     0:00 grep pptp

ipbrick:~# /etc/init.d/pptpd start Starting PPTP Daemon: pptpd.

ipbrick:~# ps ax | grep pptp
