Meanwhile, I was continuing work, so statistics are available, ping style. oob-ping: 2 packets transmitted, 2 received, 0% packet loss, time 1633ms rtt min/avg/max/mdev = 226.8/248.3/269.9/21.6 us ping: 3 packets transmitted, 3 received, 0% packet loss, time 2030ms rtt min/avg/max/mdev = 0.118/0.142/0.159/0.017 ms The only difference is, that I use us instead of ms. That could confuse some users. What do you think, stay at us or use ms? BTW: This is in a VM, that's the reason for the bad timing.
