This bug was fixed in version 2.24.2-1 of logger(1). A workaround is to specify a socket (which is then ignored): logger -n <ip> -d -P 514 -u /tmp/ignored Message That worked for me, using logger from util-linux 2.20.1 on Ubuntu 14.04. See link from hackru's answer, especially message #15.

Assume you have server.example.com.key and server.example.com.csr. Your CA sends you back your certificate, server.example.com.crt, and ...

tcpdump (and its replacement tshark) defaults to the "lowest numbered" interface. Typically this is eth0. In order to capture traffic on the OpenVPN interface tun0 you need something like this, tcpdump -i tun0 port 6514. (The interface name any can be used to capture on all interfaces.) See if you get any syslog traffic there. Another thing to try is to see ...
