Hi! first of all, thanks for your work, siege it is really simple and helpful.

Now the situation, I have encounter an error when trying to test a simple httpserver written in C but, when I hit the endpoint (that is accesible from the browser and simple curl) got a socket error. But I can use my local address to test.

I don´t really know where to look at, thanks in advance on any hint!

Setup

  • siege version 4.1.7-b5 (compiled from source commit 3836e87)
  • Debian 12 Bookworm
  • http server example commit dfbc4da

Siege

$ siege -V
SIEGE 4.1.7-b5

$ siege -D -g -v http://localhost:8080
[debug] browser.c:914 attempting connection to localhost:8080

[error] socket: unable to connect sock.c:282: Connection refused
[debug] browser.c:941 connection failed. error 111(Connection refused)

Curl

$ curl -v http://localhost:8080
*   Trying 127.0.0.1:8080...

and while searching for shared experiences this link was helpful, because when trying with my local ip address it begin the siege with no problems.
