$ logger -n localhost --udp "this is my message"
What I expected to happen: my message would get sent to port 514 UDP.
What happened instead: nothing went to port 514, but it did get written
to /dev/log.
If I run:
$ tcpdump -i lo -s 0 -A port 514
while doing this, I get no output. If I strace the logger process, I
can see it create a UDP socket, connect to the appropriate address and
port, then not send anything on that port. I can also see it send to
/dev/log:
$ strace -e network logger -n localhost --udp "this is my message"
socket(PF_FILE, SOCK_STREAM|SOCK_CLOEXEC|SOCK_NONBLOCK, 0) = 3
connect(3, {sa_family=AF_FILE, path="/var/run/nscd/socket"}, 110) = -1 ENOENT
(No such file or directory)
socket(PF_FILE, SOCK_STREAM|SOCK_CLOEXEC|SOCK_NONBLOCK, 0) = 3
connect(3, {sa_family=AF_FILE, path="/var/run/nscd/socket"}, 110) = -1 ENOENT
(No such file or directory)
socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 3
connect(3, {sa_family=AF_INET, sin_port=htons(514),
sin_addr=inet_addr("127.0.0.1")}, 16) = 0
socket(PF_FILE, SOCK_DGRAM|SOCK_CLOEXEC, 0) = 1
connect(1, {sa_family=AF_FILE, path="/dev/log"}, 110) = 0
sendto(1, "<13>Jun 7 01:06:49 logger: this"..., 46, MSG_NOSIGNAL, NULL, 0) = 46
