Recently I moved offices and took my unRAID box to a new location, where I have a new router. Now trying to get the system back up & running.

 

My understanding was moving the server to a new network would only require me to update 3 things in the network.cfg file:

1) IP

2) Netmask

3) Gateway

 

Am I wrong?

 

The router at my new location obviously has different external IP, gateway & subnet addresses that I would think I need to update. I tried using those and every time I try to go to the IP from my browser the address times out.

 

I went into the network settings of some local Macs also on this new network, saw they were using DHCP and had their own 192.168 addresses, so I tried to use those too (with a different unique identifier at the end)... still no dice.

 

Can anyone help me further diagnose this issue? Would love to get my unRAID box back up & running

Your unraid shouldn't be accessing the external network.

Your new service works like this:

A cable comes into the office...on the end is a ROUTER that sits between the outside world and the devices in your office.

FROM THE POINT OF VIEW OF THE DEVICES IN YOUR OFFICE:

That router's address is either 192.168.1.1 or 192.16.1.2  (might be 10.10.10.1, also).

That number is important because its how unRAID finds the router.

The IP numbers to the outside world are NOT IMPORTANT to unRAID. Its the job of the Router to translate between internal and external addresses.

Therefore, you should not change anything in your unRAID--except maybe the router's IP address--...it probably will work fine.

 

Now...the underlined sentence above points out that the router between the inner and outer networks may have different IP numbers if you've moved. THIS NUMBER is determined (typically) by your choice of internet provider.  You may need to update your unRAID network.cfg if you've changed providers.

 

Here's an example my network.cfg:

# Generated settings:

USE_DHCP="no"

IPADDR="192.168.1.50"

NETMASK="255.255.255.0"

GATEWAY="192.168.1.1"

DHCP_KEEPRESOLV="no"

DNS_SERVER1="192.168.1.1"

DNS_SERVER2="71.252.0.12"

DNS_SERVER3="8.8.4.4"

BONDING="no"

BONDING_MODE="1"

 

In BOLD is the only thing that should need to be changed and then, only *IF* the external/internal router has a new 'Gateway' address.

 

---

Having said all that, This is of course, the Internet, so there are-of course-some weird cases. if the above doesn't work, post the contents of your network.cfg file from your flash drive. (its in the config folder) 

 

Many thanks for your reply Dale.

 

So the GATEWAY address in my network.cfg is not the GATEWAY address written on my router box from my new ISP? They left me with some new numbers for IP, Gateway & Subnet (all different obviously from my old location)- but I'm guessing those aren't important to unRAID?

 

When I look in the network settings of other computers using the new network wirelessly without issue, I see that they have a a Router address of 192.168.44.1 (which, from my googling, I guess "Router" means "Gateway" on Mac OS?) Here's the network settings from one of those computers already using the new network:

 

This is what's currently in my network.cfg file:

 

# Generated network settings

USE_DHCP=no

IPADDR=192.168.44.99

NETMASK=255.255.255.0

GATEWAY=192.168.44.1

 

... and when I type 192.168.44.99 into a browser, nothing happens.

What do you get from console with

ifconfig

ifconfig results:

 

eth0

Link encap:Ethernet

inet addr:192.168.44.99

Bcast:192.168.44.255

Mask:255.255.255.0

 

lo

Link encap:Local loopback

inet addr:127.0.0.1

Mask:255.0.0.0

UP LOOPBACK RUNNING

MTU:65536

Metric:1

 

some other details about RX & TX packets, but no errors/drops.

What about "ethtool eth0"?

Does it ping?

 

What are the ip, mask, and gateway of the machine you are trying to access it from?

Hey guys... so this is probably the issue.. the server doesn't ping.

 

Ping results from 8.8.8.8: http://imgur.com/etqMOap

When I plug the cat6 cable feeding the unRAID server directly into a machine (iMac), there are no connectivity issues after disabling WiFi, so that connection to that router port should be fine.

 

Any thoughts? Thanks for the insight.

 

 

Ethtool shows no connection. Make sure the cable is plugged in.

Wow. My server motherboard has 3 ethernet ports, two of them return no signal, and the last one worked.

 

unRAID server restored!!

 

Very odd, but thankful nonetheless for everyone's responses. Can sleep better tonight for sure.
