Here, you need to add "balance", because a listen entry cannot have no server. In the past (v1.0 days, when "balance" did not exist), the common behaviour was to have static servers only, which is still the default case. You had to enter a "dispatch" address, which is still supported and which should go away IMHO. Since you have none of them, haproxy complains. A trick is already there to accept "balance" with no server specifically to handle this case :-)

see above for "balance"

we're using "socat" for this :

# echo "show stat" | socat unix-connect:/tmp/stats stdio # echo "show info" | socat unix-connect:/tmp/stats stdio

It works like a charm. If you don't have it though, I don't know how you could connect there (unless you're willing to write your own tools).
