#630 closed Bug / Defect (fixed)

auth-user-pass broken when using systemd

Reported by: gcau Owned by:
Priority: major Milestone:
Component: Generic / unclassified Version: OpenVPN 2.3.8 (Community Ed)
Severity: Not set (select this one, unless your'e a OpenVPN developer) Keywords:


Since 2.3.8 auth-user-pass fails to get stdin for username/password when started via systemd.

Error log:

neither stdin nor stderr are a tty device, can't ask for Auth password. If you used --daemon, you need to use --askpass to make passphrase-protected keys work, and you can not use --auth-nocache.

Setting --askpass does not work either (there is no client cert), and --auth-nocache is not used.

Reverting to 2.3.7 fix the issue.

systemd service file:

Description=OpenVPN tunnel for %I

ExecStart=/usr/sbin/openvpn --cd /etc/openvpn/client --config %i.conf --daemon --writepid /var/run/openvpn/
DeviceAllow=/dev/null rw
DeviceAllow=/dev/net/tun rw

Can you please try to build git master and see if our changes there have improved things for you?

I need to revisit this... still on my plate, but there was so much going on recently that I could not find time yet.

I think the patch I have attached should fix all issues - as in: I've tested all cases that I can reproduce here (no systemd, but auth-user-pass and passphrase-protected keys), and I understand why I broke systemd - the "do we have systemd?" branch happens right inside get_console_input() which I did not want to touch initially.

Could you please test this? Patch is against master, but should apply just as is to 2.3.8 or release/2.3 branch.

If this works, it will be part of 2.3.9 which will be shipped in the next few days.

Looks to work fine for me against the 2.3.8 version.

Thanks a lot
