Absolute beginner needs help with networking

Featured Replies

Hello,

 

Let me preface this by saying that I have never used any form of Linux in my life, so please keep that in mind if you can help me.

 

I started off by creating a flash drive boot disc following the instructions on the LimeTech support page. I then booted my test PC with the flash drive and I get a menu that allows me to choose unRAID OS or memtest86+. I choose unRAID OS and then I see a lot of stuff go by as it loads bzimage and bzroot, and then things fly by even faster loading a lot of other stuff that I have no idea about. After it is done I land with a message saying "Welcome to Linux 2.6.32.9-unRAID (tty1) and below that I have a prompt that reads: Tower login:  - That's as far as I know how to go here and I am assuming that all is well, though I have an eerie feeling that my assumption is incorrect.

 

I open up either Internet Explorer or Firefox on another computer on my LAN and I type in "//Tower" (without the quotes) and hit enter. I get a message saying "Sorry, the website Tower can not be found". I also tried exploring my network and I can not see "Tower" on it anywhere. So now my assumption is that I am not connecting to the network properly.

 

A friend suggested that maybe my motherboard's onboard NIC is the problem, so I disabled it and tried installing, in PCI slots, 4 other NICs that I had hanging around, but I have the same problem with all of them - //Tower can not be found. All 4 of those NICs, as well as the one on the mobo, all work absolutely fine under Windows 7. So I am now at a complete loss as to what to do from here. I don't even know how to get past the login prompt to test the network, nor do I have any idea how the syntax works to do it even if I could get past the prompt.

 

Here is the relevant hardware information:

 

Asus M4A78LT-M LE motherboard (has ONBOARD ATHEROS AR8131 PCI-ETHERNET CONTROLLER)

Linksys RV042 Gigabit router

Netgear GS116 16 port gigabit switch

 

My hopes were to build a 20 drive media server using unRAID, but I don't want to invest until I know that I can get this working.

 

Thanks in advance!

Did you try entering URL as "http://tower"?

 

Are you sure that the network cable is connected securely from the unRAID box to your router or switch?

 

Look here for information from the FAQ about diagnosing network problems.

 

If those don't help, you need to post a syslog.  Follow the troubleshooting link in my sig for instructions.

I'm a noob myself, correct me if i'm wrong, but you have to access it by using the ip address of the unraid server.

to get the ip address just type in 'root' at the tower login no password then type in "ifconfig" and you should see the ip address just type in that ip address on whater system you are using to access the server and you should get to your server.

 

Like i said im a noob also i'm sure someone will correct me if i'm wrong

Yup...no love...:(

Yes, the PC is about 6 feet away from my switch. I have tried 5 or 6 different cables. Don't forget...Windows networks just fine with the same exact hardware.

Look here for information from the FAQ about diagnosing network problems.

I have, but since I can't get past the login prompt, I can't try any of the suggestions.

to get the ip address just type in 'root' at the tower login no password

Ah, so that's how you get by the login prompt!  :)  Thank you!

then type in "ifconfig" and you should see the ip address just type in that ip address on whater system you are using to access the server and you should get to your server.

Bingo! Give this man a cigar! I got the IP address, typed it in my browser, and now the web UI is coming up just fine. But that still doesn't explain why it would not come up with "//Tower" or "http://Tower" or even "http://Tower/main.htm". Since my router is using DHCP server, maybe I should assign a permanent IP to the server?

If those don't help, you need to post a syslog.  Follow the troubleshooting link in my sig for instructions.

Ok, now that I know how to get past the login prompt, I think I will be able to try out some of the troubleshooting suggestions. I will post back here once I have more info.

 

Thanks!

 

 

Oddwunn, I'm very curious to see if you are able to get your system to work properly.  Were you aware of the problems others have had with the NIC on your board?

Please keep us updated on your progress.  Good luck!

In your windows machine,

 

(a) Start a DOS window, in this DOS window

(b) type "nslookup"

© at prompt type "server your_gateway_ip_address" (for example,e if your gateway is at 192.168.0.10 then type "server 192.168.0.10")

(d) at prompt type "tower"

 

Post result from step (d) in this thread.

No, but after reading his post, my problem does not seem to be related.

Post result from step (d) in this thread.

Server: cdns1.cox.net

Address: 68.105.28.11

 

Non-authoritative answer:

Name:    tower.linksys.com

Address:  72.215.225.9

 

Edit: That number does not look like a gateway to me (even though my router has it listed also). I tried entering "server 192.168.1.1" (the gateway according to my SageTV HD300 box), and I got this answer:

 

Default Server: 192.168.1.1

Address: 192.168.1.1

Server: cdns1.cox.net

Address: 68.105.28.11

 

Non-authoritative answer:

Name:    tower.linksys.com

Address:  72.215.225.9

 

This probably is your public IP address your service provider Cox Cable assigned to you.

Your gateway has dual IP address (that is why it is a gateway) one public, one private. your gateway will do NAT for all connections to outside world. all servers in outside world only can see your public IP.

 

Default Server: 192.168.1.1

Address: 192.168.1.1

 

192.168.1.1 is the private IP of your gateway, type "tower" after this command and post result in here.

Address: 192.168.1.131

 

192.168.1.131 is also the IP that is reported when I run ifconfig from the console.

When I enter 192.168.1.131 in my browser I can get to the web UI. When I enter "//tower" nothing can be found.

So far so good, this prove your gateway knows how to translate tower to 192.168.1.131. So the question comes down to why your browser did not send DNS query to your gateway. start another DOS window, type "ipconfig /all" and post result in here.

Everything looks fine except node type, any reason why NETBIOS node type should be "hybrid" instead of "braodcast"?

I don't have the slightest clue. My LAN is very simple, just the 2 pieces I posted in my original post plus two 4 port Netgear switches in other rooms. The unRAID box is connected directly to the 16 port switch, as well as the computer I am trying to access it from.

Sounds like whoever install your PC or software you installed in this PC decide to make the node type to Hybid. If you are not using WINS your client PC should not in hybrid mode. If your PC is in broadcast mode, name translation request will be picked by your gateway at same network then your gateway will answer the call.

 

 

Follow this link to fix it if you know how to change registry in Windows otherwise you will need to find someone to fix it for you.
