Server OS

Arch Linux Arm

OpenVPN version

OpenVPN 2.5.7 [git:makepkg/a0f9a3e9404c8321+] armv7l-unknown-linux-gnueabihf [SSL (OpenSSL)] [LZO] [LZ4] [EPOLL] [PKCS11] [MH/PKTINFO] [AEAD] built on Jun 2 2022

Client

Linux arch linux arm 5.15.56-3-rpi-ARCH #1 SMP Fri Aug 12 04:20:40 MDT 2022 armv7l GNU/Linux

What is the bug?

Similar to
#420 and #363
I've tried on multiple machines and I end up in the same error. On my previous install of Arch Linux Arm it worked without issues. I've tried copying the easyrsa binaries to the openvpn-install script location, however it still fails to generate keys and certs.

I had the same issue. The client device could not connect to the server with this error SIGUSR1[soft,connection-reset] received, process restarting because the server hadn't properly started. I fixed it using these commands, run as root.

chown openvpn:network /etc/openvpn/ca.cert
chown openvpn:network /etc/openvpn/server_*
chown -R openvpn:network /var/log/openvpn

[angristan]

The The certificate has expired error looks like a CA issue on your system :)

As for @Rijul-A's errors, see #788

I have finally figured out how to solve my issues.

I had to change /etc/iptables/add-openvpn-rules.sh and /etc/iptables/rm-openvpn-rules.sh

#!/bin/sh
iptables -t nat -D POSTROUTING -s 10.8.0.0/24 -o eth -j MASQUERADE
iptables -D INPUT -i tun0 -j ACCEPT
iptables -D FORWARD -i eth0 -o tun0 -j ACCEPT
iptables -D FORWARD -i tun0 -o eth0 -j ACCEPT
iptables -D INPUT -i eth0 -p udp --dport 3333 -j ACCEPT

TO

#!/bin/sh
iptables -t nat -D POSTROUTING -s 10.8.0.0/24 -o end0 -j MASQUERADE
iptables -D INPUT -i tun0 -j ACCEPT
iptables -D FORWARD -i end0 -o tun0 -j ACCEPT
iptables -D FORWARD -i tun0 -o end0 -j ACCEPT
iptables -D INPUT -i end0 -p udp --dport 3333 -j ACCEPT

And had to change the owner and group of /etc/openvpn to openvpn:network so that files would load correctly.

Then run systemctl restart iptables-openvpn
And run systemctl restart openvpn-server@server
