Networking Question Regarding Gigbit Ethernet

[Carruth, Rusty]

What does traceroute say?

 

Do all computers on the network show the same ping stats to that box?

 

(All this is assuming you didn't return it to Costco yet)

 

Very interesting to me that it didn't fail during the firmware update
process!  I'll bet you didn't check all the networking parameters on the
box while it was working ok so you could compare them against the
settings when it failed, did you?

Kenn,

Thanks for the suggestion. The servers do have static IPs, and the box
in question got its IP from my DHCP server. I looked for possible IP
collision and didn't find any. I also tried giving the box a fixed IP,
and no change.

Forgive if this has already been asked/checked ... you mentioned
servers, which I assume are on static IP's, is this storage box as well?
Could it be using an IP already in use, or the wrong subnet, or grabbing
an IP from a range you've reserved? It probably wouldn't work at all if
it was, just thought I'd throw it out there.

I have a 100baseT network with several Debian servers, a mac book, and
some virtual windows. I just picked up a Western Digital My Book Live
(MBL) 2TB NAS at Costco, and powered it up on my network. The unit is
just sitting with its green light on, and the web interface is really
slow. When I ping the device, it shows somewhere from 50% to 86% packet
loss. If I ping any other computer on the network I have 0% packet loss.
I have tried moving the device to different physical plugs, and I get
the same results. 

ping results for the MBL from server A:
--- 192.168.25.213 ping statistics ---
330 packets transmitted, 152 received, 53% packet loss, time 329555ms
rtt min/avg/max/mdev = 0.208/0.273/0.650/0.048 ms

--- 192.168.25.213 ping statistics from server B ---
254 packets transmitted, 120 received, 52% packet loss, time 252998ms
rtt min/avg/max/mdev = 0.196/0.264/2.499/0.206 ms


ping results for  server A to B:
--- 192.168.25.130 ping statistics ---
340 packets transmitted, 340 received, 0% packet loss, time 338996ms
rtt min/avg/max/mdev = 0.080/0.177/0.246/0.030 ms

The device says gigabit Ethernet next to the Ethernet port. Is there any
reason I can't connect a gigabit Ethernet device to a 100baseT network
other than the obvious speed difference? Should I see all this packet
loss? This is actually the second unit I have tried - the first one
acted the same way, so I took it back. I am now wondering if I am doing
something wrong.


Thanks!

Mark
