[PATCH v3 2/9] connect.c: replace signal() with sigaction()
From the signal(2) man page:
The behavior of signal() varies across UNIX versions, and has also var‐
ied historically across different versions of Linux. Avoid its use:
use sigaction(2) instead.
Replaced signal() with sigaction() in connect.c
