First, I am a total newbie to unRAID. I have a little experience with linux, but I am by no means a superuser...I hope somebody here can help me.

I downloaded and installed unRAID 6 free trial and got it to boot on an old server. I can login as root on the server. I edited the network.config file to assign a static IP and not use DHCP because it is on an AD domain:

# Generated network settings

USE_DHCP=no

IPADDR=192.168.0.235

NETMASK=255.255.255.0

GATEWAY=192.168.0.1

When I try to access the webgui on another computer on the same network through any web browser I get a connection_timed_ out error. I tried to telnet  and no luck there either. All support seems to assume you can get to the webgui, so I cannot use any of those posts or the telnet ones(seems like troubleshooting should maybe start with what to do if you cannot access the server by telnet or webgui). I found a post which told me to type diagnostics at the prompt so I did that. Attached is the tower-diagnostics file.  I am trying to repurpose an old server as a storage device for backups. Any help would be greatly appreciated.

You did use the IP address (192.168.0.235) as the address of server and not its name? 

Can you ping IP of the server?

 

Can you ping IP of the server?

And can you ping the gateway address from unraid's local console?

destination host unreachable when trying to ping 192.168.0.1 from the server prompt, started a continuous ping attempt, had to hard shutdown server to stop it.

restarted server and tried to ping the ip address from a different workstation: Destination Host unreachable

Your motherboard has two ethernet ports, have you tried changing ports?

Yes, switched when I first could not connect.

How about the port on the switch side.

 

It's not connecting to the other end..saw this in your logs:

 

	Speed: Unknown!
Duplex: Unknown! (255)

 

If switching ports on the switch doesnt work, try a new cat5e cable.

@MrHexen:

Thank you! New cable worked! Can now login to WebGUI. I guess I should have checked that, but the cable was the last thing I would have suspected as it had been in use before.

How do I mark this thread as solved?

Make sure you cut that cable in half and file it under "G".

 

You can mark it solved by editting your first post and changing the title and icon.

OK, so I rebooted the server(from the WebGUI) after registering and added three 3TB drives, now I cannot access the WebGUI again?

I hate to state the obvious. But have you checked the cable to make sure its still properly plugged in?

 

Yes,I have lights on the back of the server, and I just tested the cable with an Ethernet continuity tester and it Passed. Is there something I can run from the server prompt?

ifconfig

and

ethtool eth0

Here is the  current diagnostics file from the server

I edited the network.config file... DHCP was turned back on. changed it to "no" and I can access the WebGUI again. Thanks for all your help!

addendum:

the server and RAID controller are too old, and do not recognize 3TB drives(showing 750gb in POST) and no drives are showing in array devices. I think that just stuck a fork in it, it's done.

Many thanks to all who replied.
