Hello, everybody!
I used FreeBSD for some time, but did not dig so deep in Network Connections Parameters… Installed FreeBSD 10.1 on a NetBook (with a broken screen) Samsung NP‑NC10‑KA04RU (Intel® Atom™ N270 Diamondville-SC 1.60 GHz, HT, Mobile Intel® Calistoga‑GSE i945GSE, 1024 MB DDR2‑667, Marvell Yukon 88E8040 PCI-E Fast Ethernet Controller). It works, but I get constant packet loss 22% - 27%, when pinging this Machine. This server is connected with another machine (Ubuntu Linux) via switch D‑Link DES‑1005A.
I used the following command to check the network::
Ping FreeBSD -> Linux 1.065 ms, 0.0% packet loss
Ping FreeBSD -> Yandex.Ru 5.883 ms, 0.0% packet loss
Ping Linux -> FreeBSD 1.008 ms, 22% packet loss
Ping FreeBSD -> LocalHost 0.041 ms, 27.0% packet loss
Ping Linux -> LocalHost 0.017 ms, 0% packet loss
I think, that the trouble is in the some FreeBSD network settings, because I encountered about the same results on another machine (P4+RealTek NIC) on FreeBSD 9.1 and on a virtual machine (VMWare WorkStation) too.
Can anyone tell me, please, which way to dig to fix this behavior?
