ping with time stamp

[ylevy]

Hello all,

At Red-Hat OS there is the following ping command:

[root@pxehost-32-82 tmp]# ping -i 0.2 -T tsonly 10.10.32.160
PING 1.0.0.1 (10.10.32.160) 56(124) bytes of data.
64 bytes from 1.0.0.1: icmp_seq=1 ttl=64 time=0.225 ms
TS:     33740603 absolute  <<<<<<<<<===============
        642738
        0
        -642738

64 bytes from 1.0.0.1: icmp_seq=2 ttl=64 time=0.195 ms
TS:     33740803 absolute   <<<<<<<<<===============
        642738
        0
        -642738

This is time stamp, and we see the delta between two ping acks arrived.

The question is:
How we can do that at free-bsd FreeBSD?

Rgds.

# ping -i 0.2 -M time 10.10.32.160

See ping(8).

OK, thanks.

What about a better resolution?
