client-connect not working

Post by john_paul » Sun Oct 20, 2019 11:16 am

I am trying to figure out what I'm doing wrong. I have the following lines in my server.conf file

script-security 2
client-connect /etc/openvpn/scripts/connect.sh

and the connect.sh file has the following content

#!/bin/bash
/usr/bin/touch /tmp/connected

with chmod 755 permissions on the script file. Yet when a client connects nothing appears in the /tmp/ directory.
The openvpn.log file has no mention of running a client-connect script. How can I diagnose this problem?

Here is my full config file (minus sensitive information)

server.conf
dev tun
proto udp
port 1194
ca /etc/openvpn/easy-rsa/pki/ca.crt
cert /etc/openvpn/easy-rsa/pki/issued/********.crt
key /etc/openvpn/easy-rsa/pki/private/********.key
dh none
topology subnet
server 10.8.0.0 255.255.255.0
# Set your primary domain name server address for clients
push "dhcp-option DNS 208.67.222.222"
push "dhcp-option DNS 208.67.220.220"
# Prevent DNS leaks on Windows
push "block-outside-dns"
# Override the Client default gateway by using 0.0.0.0/1 and
# 128.0.0.0/1 rather than 0.0.0.0/0. This has the benefit of
# overriding but not wiping out the original default gateway.

Raspbian 9.1 (stretch).
I installed OpenVPN with PiVPN.

Take a look at the systemd unit file.

This is the contents of /lib/systemd/system/openvpn.service

Code: Select all

[Unit]
Description=OpenVPN service
After=network.target

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/bin/true
ExecReload=/bin/true
WorkingDirectory=/etc/openvpn

[Install]
WantedBy=multi-user.target
Is there something wrong with this?
Thanks for the suggestion.

OK, I found it. There were several other systemd files including:
/lib/systemd/system/openvpn@.service
/lib/systemd/system/openvpn-server@.service
which had the setting

Code: Select all

PrivateTmp=true
This was causing the problem.
Thanks for making me double check!
