I'm trying to get something called MythTV working accross multiple PCs.
In a nutshell, it consists of:
- A "Server" PC with TV tuner cards on it which records shows and stores them on it's hard drive
- One or more "Viewer" PCss that connect to the server to view recorded shows
But the setup isn't working for me. Something to do with with my routers is my first suspicion.
A "Viewer" PC is names "eee901".
When I ping that box from different PCs on the same LAN I get different results.
From my main PC - not the "Server", just one that I do most of my work on, I get an expected result: -------------------------------------------------- C:\>ping eee901
Pinging eee901 [192.168.0.109] with 32 bytes of d

From the "Viewer" PC, I get two unexpected results - from two different Pings: -------------------------------------------------- x[ at ]eee901:-$ sudo ping eee901 [sudo] password for x:
PING eee901 (63.251.179.13) 56(84 bytes of data. --------------------------------------------------
Yet, on a prior ping, I got: -------------------------------------------------- 64 bytes from 8.15.7.117: icmp_seq=01 ttl=53 time=15.8ms --------------------------------------------------
Does this tell something to somebody who knows more than Yours Truly?
The network looks like this:
LinkSys "N" wireless router ===> eee901 ^ | Verizon FIOS ====> Verizon Router ===> Main PC
Wireless disabled on the Verizon router. LinkSys wireless router has DHCP disabled. Connection between LinkSys and eee901 is WiFi.

It seems to me some of computers are using different subnets. Posting the results of ipconfig /all on all computers may help.

What seems to be happening is that you're using the DNS server(s) supplied by Verizon to look up "eee901" and it's resolving that to various places out on the Internet.
For local name resolution, you should explicitly enable NetBIOS over TCP (NetBT). You'll need to check your node types as well. See http://networking.nitecruzr.net/2005/05/address-resolution-on-lan.html

Hi Not clear what exactly you are doing. Ping eee901 [192.168.0.109] seems like a local IP so it is very fast. PING eee901 (63.251.179.13) is pinging to an external address on the Internet so it is much slower and it should be like this. Jack (MS, MVP-Networking)

Well, eee901 cannot be 63.251.179.3, 8.15.7.117, and 192.168.0.109. The most likely cause is an improper setup of the Linksys router. What you must do for this device is convert it to a switch. Doesn't the router manual tell you how to do that? Why can't you use wireless in the Verizon router? Jim

I wanted to use the LinkSys bc it does "N".
Sounds like I need to dig through the manual to get the real deal on making it a switch. What I did so far was on hear-say. Basically just turned off DHCP and assigned an IP address within the other router's mask.
Just on GPs, I set all five of my PC addresses to Static in the D-Link router.
Dunno if it changed anything, but in testing it I have established that, using IP addresses, everybody can ping everybody else.
But anybody attached to the LinkSys router cannot ping by device name. It's like there's some kind of pointer that I'm not setting that tells it where to go first for it's DSN lookups.
Now I'm gonna dredge up the LinkSys' instructions and take it from the top...

It's always a good idea to RTFM, but your problem is most likely not your router's configuration. Do an ipconfig /all on your computers and you will almost certainly see the entry for DNS either pointing to the IP address of your Verizon router or (more likely) a DNS server owned by Verizon out on the 'net.
Because your pings are resolving to public Internet addresses, these addresses most likely are coming from Verizon's DNS server. This probably is caused either by NetBT not running on some (or all) of your LAN computers or some other problem with the Browser Service. In addition to the article from Chuck that is linked in my previous post (http://networking.nitecruzr.net/2005/05/address-resolution-on-lan.html), see some of Chuck's other very helpful information:

Before you introduced "NetBT", I was thinking I had to find the place in the LinkSys' setup that told it where to go for DSN lookups.
Now it sounds to me like lack of NetBT might be the prime candidate.
Have I got it right? -- PeteCresswell

One of the methods *Windows XP* uses to resolve host names over a TCP/IP network is to broadcast NetBIOS Name Query Requests.
I'm not as conversant with how Linux does name resolution, but I doubt if it's the same as Windows. You should probably Google for "Linux LAN name resolution" and this hit looks as if it might be helpful: http://ubuntuforums.org/showthread.php?t=405662 As does this one on configuring Samba: http://www.swerdna.net.au/linhowtosambabrowse.html
Although there are some folks who read posts in these Windows newsgroups who also understand Linux networking, you're more likely to get answers from them if you include Linux in your subject, e.g., "name resolution problem in a mixed XP/Linux network". OTOH, because your problem seems to be with the Linux configuration, you'll probably get more and better responses in a Linux newsgroup, e.g., comp.os.linux.networking

To configure the router as a WAP what you said is correct (" Basically just turned off DHCP and assigned an IP address within the other router's mask.") assuming the IP address you're using is in right subnet for the Vz router but outside it's DHCP address. Additionally, note that the cable from the Verizon router should be going to a LAN Port on the Linksys, and not the WAN/Uplink port. --

I don't mean to nitpick. You must have missed his original post, specifically the following:

I kept quiet as soon as I noticed Pete's problem was related a machine with "sudo" command :-p

I also went a step further and defined each of my 4 PCs in the router's Static IP table.... if only for the comfort of being able to print out the list and know that *that's* the address for *this* box.... now and forever. -- PeteCresswell

I've heard from quite a number of Linux users what a great system it is and how poor MS' OS' are.
Having said that - and being of reasonable intelligence, and making a decent living writing software....
So far, I've found Linux to be a serious time sink.
My experience with Windows XP is like that with an appliance: you open up the box, you plug it in, and you use it. Linux, OTOH, is more like a hobby or a second job - except that the pay is lousy. -- PeteCresswell

"Sudo" no more.
I finally gave up on Linux and put XP Pro on it.
For me, at least, XP Pro is like a toaster: I bring it home, I unpack it, I plug it in, and I start making toast.
Linux... Sheesh!.... It's like having a part-time job, except the pay isn't very good.
Also, contra-intuitive as it may seem, Ubuntu took 61 seconds from a cold start to a usable desktop. XP took 24 seconds last time I put a clock on it. Will probably get longer when I finish installing MS Office and a lot of other stuff.... but the Ubuntu build didn't have much on it either. -- PeteCresswell

<grin> I like the analogy. Welcome to the *real world* of Windows -vs- Linux. Much of the hype about Linux in general is just political correctness amongst a world that is predominantly anti-Microsoft. The same can be said for Mac/Apple. Linux does a fine job in the right situations where it is well suited and we run a pretty good chunk of Linux boxes around here,...but it is just another Operating System, there is nothing mystical or magical about it.
