FreeNAS cannot ping through CISCO switch

[TwittyFlash]

Dear All,

For some reason, my FreeNAS server was unable to be ping-ed one fine morning.
After running the "service nginx restart' and the "Service django restart" i was able to able to ping through a directly but still unable to ping through a CISCO switch which has not changed any of its settings from day one.
Previously I was able to ping smoothly to and from all devices with switch or not.

The server and PCs cannot view each other even after running 'arp -a" commands.
Ping results from the server was:

ping: send to : Host is down

Ping results from the other end was:

"Destination host unreachable"
Even after putting in the CD to do a reinstall/upgrade keeping the settings intact does not help.

Some information about my system:

• FreeNAS 9.3.1 , x64 bit.
• CPU: Intel Xeon Processor dual core
• DFI Motherboard
• Intel Network card

Most of the time I am using the in-built ethernet port.
The only things I was doing previously was trying to untar some jdk files downloaded online,trying to install it in the /usr folder, only to realise that the freenas does not recognise it . Could that be the cause?
Hope to obtain useful solution so that I do not have to keep usng reinstall as the only solution.

Greatly appreciate any useful advice in advance.

Can freenas ping anything? Gateway, other hosts or Google?

 

[TwittyFlash]

well it's a small LAN with a couple of computers. There is no official Gateway yet.
Only through a direct peer to peer connection can there be any response from both ways.
As for pinging to Google ,
It received the " ping : cannot resolve www.google.com: Host name lookup failure."

What ever you did with the jar probably didn't break anything in the network but I really have no way of knowing exactly what you did.

If this is a peer to peer connection why are you asking questions about a switch? Do you mean you don't have a router so you just connect everything to a switch, assign static ip's and setup routes for every host? Seems like a really complicated setup.

 

[TwittyFlash]

No router, setup static addresses, yes, but not routes. The hosts are of the same subnet group.Not complicated.

Switches can go bad.

 

[TwittyFlash]

Well, all my other hosts could ping /communicate with each other, except for FreeNAS server. I suppose some settings could have changed or gone bad to cause this.

What kind of cisco switch?

Apologies the late reply. Not been working on freenas recently.

Not to sound to "Windows'ish", but have you rebooted FreeNAS since then?

Is that /usr in a jail in FreeNAS itself? Mucking around with the internals of FreeNAS in this way does put you on the fast track to breaking your system.

Have you tried a different port on the switch? Sometimes ports go bad.

start up your pings so they're pinging between your various devices. (even if they're not responding)

then log on to the switch and run "show mac address-table"

then find the ethernet address for all your devices.

ifconfig -a will tell you the ethernet address for your interface on the freenas box. If you don't know how, I'm sure a windows guru can help you figure out the ethernet addresses of your other devices.

Take your list of devices and compare them to the output of the mac address table on the switch. If everything appears on the expected ports, then you probably have an IP configuration problem.
If some addresses don't appear, you might have a plumbing problem, or you might have a larger configuration problem.

Do a "show run" and make sure the port you plugged into doesn't have an old config on it or possible port shutdown
