# perform primitive simulation of a socks4 server with echo function via stdio.
# accepts and answers correct SOCKS4 requests, but then just echoes data.
# it is required for test.sh
# for TCP, use this script as:
# socat tcp-l:1080,reuseaddr,crlf system:"socks4echo.sh"

#if echo a |read -n 1 null >/dev/null 2>&1; then
#    HAVE_READ_N=1
#else
    # and newer bash (4.3) has some other problem with read -n
