Hello,

 

My server has recently disappeared from the network after a reboot.  The server seems to boot up fine, but I can not reach it from another computer on the network.  It obtains an IP address during boot and the router activity light flashes on and off a couple of times but then after boot the router reports the server as being off and the light is no longer there.

 

If I am on the server and try to ping out I get "connect: network is unreachable"

 

I ran the following commands:

 

ethtool eth0:

 

Settings for eth0:

Any ideas?

 

Thank you

 

 

 

 

 

 

 

Syslog attached

 

syslog.txt

No network is being detected as shown in both the ethtool output

 

  Link detected: no

 

and in the ifconfig output (no IP address assigned)

 

Most likely suspect is a faulty cable.  Second most likely is a bad port on the router, or a bad network interface in the unRAID server.

 

It is NOT obtaining an IP address when it boots.

 

The syslog shows:

Sep 13 21:45:09 Tower ifplugd(eth0)[1271]: ifplugd 0.28 initializing.

Good luck. 

Thank you.  My testing suggests the NIC is bad.  Luckily I am within my 30 day replacement so amazon is shipping me a new board.
