Di mesin server (10.10.0.2)

nc -vvlnp 12345 >/dev/null

Di sisi client kirim gigabyte zero melalui dd lewat nc tunnel

dd if=/dev/zero bs=1M count=1K | nc -vvn 10.10.0.2 12345

Waktu demo akan keluar kira-kira

$ dd if=/dev/zero bs=1M count=1K | nc -vvn 10.10.0.2 12345
Connection to 10.10.0.2 12345 port [tcp/*] succeeded!
1024+0 records in
1024+0 records out
1073741824 bytes (1.1 GB) copied, 9.11995 s, 118 MB/s

Perhatikan bahwa hasilnya dalam megabyte per detik, perlu dikali 8 untuk dapat megabit per detik.
