FreeNAS Box Stopped Seeing Network

[RandomTask]

I have a FreeNAS 9.2-RELEASE-p12 box that has stopped being able to see anything on the local network (let alone the internet at large).

This box has a static IP: 192.168.2.248.

It is directly connected to a router (192.168.2.1) via an ethernet cable.

The router is serving out IPs from 192.168.2.2 to 192.168.2.100 via DHCP. There are other devices with static IPs outside that range that have access to the network and internet via this router, they are unaffected.

Attempting to ping either the router or Google results in no packets being received:

Code:

# ping -c 3 192.168.2.1
PING 192.168.2.1 (192.168.2.1): 56 data bytes

--- 192.168.2.1 ping statistics ---
3 packets transmitted, 0 packets received, 100.0% packet loss

# ping -c 3 www.google.ca #Obviously this will fail now, but the error is different
ping: cannot resolve www.google.ca: Host name lookup failure

I've gone through the automated setup to remove and re-add my interface "em0" but I still can't see anything on my local network or the internet.

Here's the contents of my /etc/resolv.conf:

Code:

search local # Is this maybe the culprit?
nameserver 192.168.2.1 # I added this just in case
nameserver 8.8.8.8
nameserver 8.8.4.4

and the contents of my /etc/rc.conf file:

Code:

Any help would be much appreciated! I'm typically a fairly decent Linux guy, but am slowly learning the nuances of BSD!

Also post the output of ifconfig.

Sorry for the delay, I don't have access to my box during the day (hoping to fix that eventually with VPN).

Here's the output of ifconfig:

I've also updated my initial post with this information.

One other thing I just noticed (that I didn't notice initially) is that I'm seeing the following error message:

Code:

Jul 8 20:26:20 Hades nmbd[2819]: [2016/07/08 20:26:20.960120,0] ../source3/libsmb/nmblib.c:873(send_udp)
Jul 8 20:26:20 Hades nmbd[2819]: Packet send failed to 182.168.2.255(138) ERRNO=No buffer space available

 

[dlavigne]

Do you remember which driver you were using or is plugged into the network. Right now, neither em0 or alc0 has a carrier...

 

[RandomTask]

I haven't manually configured anything for this box all I've done is Option #1 in the quick start menu (the 1-11 console menu after FreeNAS is booted). In theory it should all be automatic.

 

[dlavigne]

That's not going to help if you don' t have a carrier... Check the cables, the switch, etc.

 

[RandomTask]

I don't understand why anything would have changed. I haven't changed anything on this box. I believe there have been a couple small power outages (off and back on again).

I'll try using a different cable and report back.

 

[joeschmuck]

Here are some obvious steps you may have already taken...

1) Cycle power on your Router
2) Replace the Cat 5/6 cable (yes, these can and do go bad)
3) Try a different Router port

Edit: Yea, someone beat me to this. I'm a slow typier.

 

[RandomTask]

Thanks so much for the help! I can't believe it was something that simple - I could have sworn I checked that already.

It turns out the port on my router wasn't responding, as soon as I tried another it worked!

Sorry for taking up everyone's time for such a silly issue!

 

[RandomTask]

Although now my FreeNAS web management page looks like this:

Unhandled Exception
An unhandled exception was thrown by the application.

The error in my console is:

Code:

kernel: Failed to write core file for process nmbd (error 14)

I'm restarting the box now just to see if it helps at all - nope. /sigh I might just have to re-install FreeNAS.

Anyone know if I could save out a config or something so I don't have to re-do everything from scratch (shares, jails, etc.)

 

[joeschmuck]

When it rains it pours.

 

[RandomTask]

Well, I have no idea what happened, I thought I restarted the box but it turns out it was still in the process of rebooting (yet somehow the browser was still fetching the page during this process???).

Any who, thanks everyone for your help, I seem to be back up and running!
