PiVPN Install Problem

[Huffpuffin]

Hi All

Just updated to V135, and wanted to use PiVPN. Installed through Dietpi-launcher. However, I get errors as below:

Code: Select all

DietPi-Services

 The system will now reboot.
 This completes the DietPi-Software installation.

If I try to run pivpn, then I get the following:

Code: Select all

root@RPi3:~# pivpn -h
-bash: pivpn: command not found
root@RPi3:~#

I'm running a Raspberry Pi 3 (Jessie) with Webmin and Plex.

Any suggestions would be gratefully received. TIA

Edit: Sorry, just seen another error message:

** Error in `systemctl': double free or corruption

It looks like a possible bug in systemD. Occurred when running noip2 service control by the looks of it.

Does the error reoccur when you run the following?:

Code: Select all

systemctl stop noip2
systemctl start noip2

Also see if the error occurs with:

Code: Select all

dietpi-services restart

Possible PSU / SD card corruption. Can you list your PSU and SD card specs please.

This is a connection test. It will fail if wget --spider is unable to obtain a response. Usually indicates the URL is offline and/or unreachable.

Try installing PiVPN again from dietpi-software. The URL appears to be working fine for me, at the moment.

Hi Fourdee

Thanks for the prompt reply.

Tried all options suggested, but no joy - still seeing same error messages.

SD card is Kingston 8GB, but this is only used as boot; root filesystem is on a 32GB Sandisk USB flash drive.

PSU: have tried a Samsung 2A PSU, and another (Power Pak) 2 x 2A PSU. Problem is still there.

Just a thought (from a noob) - as Noip is mentioned, would it be worth trying to uninstall that as well, then re-installing after PiVPN?

Hi,

I was able to replicate. Appears SystemD doesnt like the sysinit service.

This will be resolved in DietPi v136 update, however, you can patch your system now by running the following commands:

Please copy and paste all into a terminal (this is a systemD script that will replace the current one):

Code: Select all

update-rc.d noip2 remove
rm /etc/init.d/noip2
cat << _EOF_ > /etc/systemd/system/noip2.service
[Unit]
Description=noip2
After=network.target network-online.target rsyslog.service

[Service]
Type=forking
RemainAfterExit=yes

ExecStart=/usr/local/bin/noip2
ExecStop=/usr/bin/killall -w noip2

[Install]
WantedBy=multi-user.target
_EOF_
#systemctl enable noip2.service
systemctl daemon-reload

You can use dietpi-config > networking options: NAS/MISC to enter the noip creds. Once done, please reboot and check service is running with (please paste results):

Code: Select all

systemctl status noip2 -l

Hi Fourdee

Sorry for not coming back sooner. When I went to check for your reply, I saw the update to v136. I have run this update now.

The result of 'systemctl status' is:

Code: Select all

When I try to login to PiVPN (even after reinstalling), I still get the following:

Code: Select all

root@RPi3:~# pivpn
-bash: pivpn: command not found
root@RPi3:~#

When I uninstall PiVPN I notice the following:

Sorry to be a pain, but any more pointers?

Hi

Looks like PiVPN wasnt actually installed, hence the missing command.

https://install.pivpn.io

Connection test failed. Either website was down, or, no route to website.

Can you run the following command and paste results please:

Code: Select all

ping -c 1 pivpn.io
/DietPi/dietpi/func/check_connection https://install.pivpn.io

[Huffpuffin]

Hi Fourdee

Thanks for coming back to me. I tried uninstalling PiVPN, then installing manually via http://www.pivpn.io/

This seems to work fine.

Thanks for looking at this, but I am happy to consider this issue closed now.

Can I just say that I think your project is awesome - thanks for all your hard work!

FYI the output from your test commands was:

Code: Select all
