within my config file. When starting openvpn via

I get a username/password prompt. Journal -xn shows

Please try the openvpn prepared systemd unit file openvpn-client@.service

There is also a openvpn-server@.service version.

Code: Select all

# systemctl disable openvpn@german
# systemctl enable openvpn-client@german
# systemctl reboot

Could it be a problem with systemd-ask-password-wall.service ?

Please post your client log file at --verb 4

Also, to use the openvpn-client@.service the openvpn client config file needs to be located in
/etc/openvpn/client/Germany.conf

Is your OS up to date ? (eg. systemctl --version & uname -a)

It would also help if you post your openvpn config file and openvpn log file @ --verb 4

Yes, Debian Jessie latest updates installed

Here is my config

Code: Select all


client
dev tun
proto tcp
remote XXXXXX 501
resolv-retry infinite
nobind
persist-key
persist-tun
cipher aes-256-cbc
auth sha256
auth-user-pass /etc/openvpn/auth-pia
tls-client
remote-cert-tls server
comp-lzo
verb 1
reneg-sec 0
crl-verify crl.rsa.4096.pem
ca ca.rsa.4096.crt
disable-occ


While copy/paste this config I notice that directive auth-user-pass is not included to clipboard. Very weird. I just deleted the whole line and recreated, NOW it works. Well, no clue what happened

Perhaps something to do with your first post:
