How restart OpenVPN server

bosko · Nov 14, 2006, 7:05 PM

When change any setting in PPTP server, automaticly PPTP server restart and close all connection.
In linux system PPTP server restart by command /etc/init.d/pptp restart
When change any setting in OPENVPN server, to have to restart computer, otherwise server dont work.

I have version: 1.0.1
built on Sun Oct 29 01:07:16 UTC 2006
And I get the same problem. It was working normally until today. I have had it up for about 2 days.
If I reboot the pf it works with changes, the changes get written to config.xml, but the openvpn server doesn't shutdown.

Greetings,

i have same problem with OpenVPN
Ill try many ports but with same result… When i restart pfsense, everything works fine, but when i try change settings in OpenVPN than openvpn shut down with this error message :

TCP/UDP: Socket bind failed on local address [undef]:15888: Address already in use

OpenVPN isn't being killed properly. I don't know why, maybe the machines you're using are slower (specs?).

If you want to help, please run this from a pfSense terminal (from the shell, not from the console menu):

/usr/bin/time -h sh -c 'RUNNING=`ps ax | grep openvpn | grep -v grep`; while [ -n "$RUNNING" ]; do RUNNING=`ps ax | grep openvpn | grep -v grep`;  done' | & awk '{print $3}' & echo '' | php -q

The output should be something like:

[1] 87559 87560
0.58s
[1]  + Exit 1                        /usr/bin/time -h sh -c  ... |&
       Done                          awk {print $3}

I'm interested in the second line, "0.58s" in this example.

Bredys · Nov 16, 2006, 1:11 PM

[1] 1621 1622

0.17s

[1] Exit 1 /usr/bin/time -h sh -c … |&
Done awk {print $3}

Computer configuration :
Pentium 2 - 500 Mhz
256 MBRam

jakehathaway · Nov 16, 2006, 3:35 PM

Here are my specs:
I have dual machines running a CARP config, but only one is running openvpn.
Pentium D 915
1GB RAM
2x 80GB HD (SATA)
2x Onboard Gb NIC
2x Intel Pro 1000PT Nic

Here is the output from the command at the shell:
[1] 58131 58132
0.00s
[1] + Done /usr/bin/time -h sh -c … |& awk {print $3}

Thanks for the help.

fernandotcl · Nov 16, 2006, 3:53 PM

Thanks for the quick replies. We're studying what the best way to fix it is. In the meanwhile, if you need to restart OpenVPN after performing changes to the config screen, issue:

echo "" | php -q

Bredys · Nov 16, 2006, 4:02 PM

echo "" | php -q

Same problem :( this dont help… i must restart whole box :(

Ill try 3 boxes and clean installation. First time all appear ok and i can change openvpn config without problem and its restart without error... but after some hours happend this after changing options :(

Yeah, same problem here… openvpn is not running when I run it from the command line:

# /usr/local/sbin/openvpn --config /var/etc/openvpn_server0.conf

I can't seem to find what is using 1194 when openvpn is not running.

From a shell issue a sockstat command to see what processes are listening on what ports.

*root check_relo 326 11 udp4 :1194 :

so something is wrong with check reload status… when i kill this process everything works fine!

sullrich · Nov 24, 2006, 6:47 PM

Eh, this doesn't make any sense. check_reload_status doesn't even open a socket.

Yeah, I've got another whole mess attached apparently:

Bredys · Nov 25, 2006, 9:21 AM

sockstat | grep 1194

root check_relo 405 11 udp4 *:1194 :

i try this many times… but when i try change openvpn settings, check_reload_status block port 1194. When i kill it everything work fine and i can change openvpn settings without any problem until next restart...
After restart, openvpn run ok until i try change some options...

with strong i386 hardware.

At this point I am at a loss. Will have to discuss it with the other devs. We are all really confused on this one.
