Pertama unduh dahulu pathchar. URL-nya bisa dibaca dari[1]. Lalu ekstrak pathchar. Saya menjalankan program pathchar sebagai root. Berikut ini adalah contoh hasil pathchar
./pathchar 202.153.129.162
pathchar to 202.153.129.162 (202.153.129.162)
can't find path mtu - using 1500 bytes.
doing 32 probes at each of 45 sizes (64 to 1500 by 32)
0 localhost
| 19 Mb/s, 733 us (2.08 ms), 15% dropped
1 192.168.1.1 (192.168.1.1)
| 115 Kb/s, 8.25 ms (124 ms)
2 125.163.72.1 (125.163.72.1)
| 14 Mb/s, 141 us (125 ms), +q 4.11 ms (7.08 KB)
3 125.160.0.129 (125.160.0.129)
| 3.4 Mb/s, 6.33 ms (141 ms), +q 3.89 ms (1.68 KB), 9% dropped
4 218.100.27.132 (218.100.27.132)
5 * 1 1024 1439 141 448 423 141
| 11 Mb/s, 192 us (143 ms), +q 4.07 ms (5.76 KB), 15% dropped
6 202.153.129.162 (202.153.129.162)
6 hops, rtt 31.3 ms (143 ms), bottleneck 115 Kb/s, pipe 4758 bytes
Dengan pathchar kita bisa mengetahui bottleneck jaringan berapa dan ada di mana.
