On of the reasons I'm reluctant to give out more information than what is required. No I'm not doing this over wireless, no I'm not plugging both NICs of the lmce box into the switch. I went so far as to completely disable the ip4 and 6 firewalls. Ran watch ipconfig and the dropped packets were still cranking.

Here's a dirty picture of the network lay out.
https://docs.google.com/drawings/d/16q2MupQs-oDVCizGwLtPblzh-kNESZ4_quzM27EaPrI/edit


I've recently changed it to
https://docs.google.com/drawings/d/1gNgYkh1P3Z7oS3F4_GzH5cGhrgQlPRtHePEbno-NHNk/edit

I moved to the second image to see if eth0 was the problem due to the amount of dropped packets.
My nest test I'm removing the wireless router completely. I don't think its the problem but.for through testing.

I'm not using my lmce box as a router at the moment. So my eth0 is both WAN and LAN for now. Ill do a reboot and do some more tests this weekend when I have the time.
As for the actual lay out of the etwork . My cable modem feeds my wireless router that has DD-wrt on it so I can do reserved dhcp leases to an VMware esxi server easier than static IPs. This is also so when I have friends over they. Have internet without access to my media. If once supports reserved dhcp ill be glad to make some changes.

All tests ran on fresh install, after I was getting the "better" speeds. The old install was getting KB second transfers on all files. The new install, well see my last post. I have tested connected to the eth0 port but got slower speeds on the eth1 port. So one thing at a time.
First the results of the test's you wanted. I'll do some hardware testing this weekend. I have a cable tester I can use, as for testing the nics them self's I'll use IPERF..

First of all, try to understand (draw) your connection. What's your WAN interface, what's your LAN interface (fe in my case is LAN: eth0, WAN: eth1). This way you know where you're looking. A picture is saying a lot more then some words.

Been their done that, networking 101 I have a quick and dirty google doc if you can send me an email. I'm not a complete noob just no expert.

I'll put some basic test here that can point you to the right place where to look...


Connect
Can you connect with ssh to your core? I'll assume you're using a linux client.

Code: [Select]

ssh username@192.168.80.1

Network interfaces
With ifconfig, you'll see a lot more about your network cards.

Code: [Select]

ifconfig-> do you see any errors on the interfaces (collisions)? In fact, you should only see RX/TX packets here...
-> What the subnetmask of you interfaces (the same as for your routing table)?

Code: [Select]

$ ifconfig
eth0      Link encap:Ethernet  HWaddr 20:cf:30:c0:ff:46
          inet addr:192.168.3.80  Bcast:192.168.3.255  Mask:255.255.255.0
          inet6 addr: fe80::22cf:30ff:fec0:ff46/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:643754728 errors:0 dropped:3991875718 overruns:0 frame:0
          TX packets:156841564 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:1054057917 (1.0 GB)  TX bytes:1290091923 (1.2 GB)
          Interrupt:221I noticed the dropped packets this many raises a flag

fe
For more information, you can always do following:

Code: [Select]

sudo ethtool -S eth0This should give you more information:

Code: [Select]

$ sudo ethtool -S eth0
NIC statistics:
     tx_packets: 156841598
     rx_packets: 643754748
     tx_errors: 0
     rx_errors: 0
     rx_missed: 137
     align_errors: 0
     tx_single_collisions: 0
     tx_multi_collisions: 0
     unicast: 643740548
     broadcast: 4967
     multicast: 14200
     tx_aborted: 0
     tx_underrun: 0 Not perfect but nothing big here.

Routing

Code: [Select]

netstat -rn-> should give you a clear routing table

Code: [Select]

$ netstat -rn
Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
192.168.3.0     0.0.0.0         255.255.255.0   U         0 0          0 eth0
192.168.80.0    0.0.0.0         255.255.255.0   U         0 0          0 eth1
169.254.0.0     0.0.0.0         255.255.0.0     U         0 0          0 eth0
239.0.0.0       0.0.0.0         255.0.0.0       U         0 0          0 eth1

Traceroute
With a traceroute you'll see the connection path. This is useful to see where your connections goes, and if any devices are taking a long time to respond.
This is best done from you client machine on (i don't have direct access to a client now, so i can't show you my result, sorry).

Code: [Select]

traceroute linuxmce.org
fe (this is done from another network, so it won't be the same for you). The most important thing in here are the first lines, with your private ip's, and the first public ip (your internetrouter):

Code: [Select]

$ traceroute linuxmce.org
traceroute to linuxmce.org (193.200.113.133), 30 hops max, 40 byte packets
 1  192.168.3.1 (192.168.3.1)  0.668 ms  1.804 ms  2.200 ms
 2  X.X.X.X (X.X.X.X)  8.378 ms  12.214 ms  13.201 ms
 3  XX.XX.XX.XXX.com (XX.XX.XX.XX)  13.566 ms  13.753 ms  13.921 ms
 4  XXX.XX.XX.XX.com (XX.XX.XX.XX)  19.750 ms  20.698 ms  23.063 ms I marked out the IPs with XXs, why your having me test the out side network is beyond me.

Send us the results of this, from there on we can maybe start troubleshoot a bit more ...

Of course, it's best that you do all this tests from all the machines (or at least all the machines that are in the loop). This is the reason why i wrote that's always best to have a small drawing beside... This way, you can isolate the problem to  a certain point/connection...

OK... I don't know what was going on but after a reinstall form scratch of LinuxMCE I'm getting much better speeds. I ran 5 quick tests of two types. Meaning I ran each test type 5 times.
First type, a folder of HD pictures ranging form 44 KB to 605KB ~ 500 pictures in all average speed 10Mb a sec.
Second type, A dvd ISO. ~4.15GB average 75MB a sec.

Again no hardware changes, only software changes on one system and that's Linuxmce.
I'll run some IPERF test's this weekend when I have more time.
Until then this is much better and workable.

here is what it comes down to:
it is fine to discuss integrating someone else's software, as long as that software is not explicitly illegal.
it is not fine to discuss techniques for circumventing the drm or encryption on the bluray discs.

OK.. got it.
Is the new VLC player illegal? I haven't found information on that.
The extra component on the other hand .... I cease and desist.
I would think such conversation was covered under the freedom speech, but I digress.
That's the last I'll speak of it.

The player on the other hand. Has any one had luck with VLC at all. I tried it once and never got any thing out of it other than a fresh install.

Thank you all for your posts. I'm not in front of my network at the moment so the testing and tweeking will have to wait.

I thought that I had mention in my original post that I have had 10Mb second transfers on the exact setup in the past(3 days ago) only difference between those speeds and now is the install of linuxmce. So I believe its safe to say its not a hardware problem.

Hello all.
I was hoping for some help on this, I'm currently experiencing poor network performance on my hybrid Kb a sec transfers.
I'm using cat6 cable and a gigabit switch, Gigabit nic's on both systems.

The lay out of the network..
Cable modem feeds-> router feeds-> Gigabit switch
Gigabit switch feeds ->
Lmce
PC

I'm getting Kb a sec here not near what I would expect getting.
The drives I'm copying to are 5400 rpm and 130.28Mb/sec using hdparm on average.
I have achieved 10Mib a sec transfers on that system in the past before Linuxmce.

Suggestions??

Out of the box, lmce doesn't play dvds, same goes for bluray. The user needs to install the appropriate libraries manually to allow DVDs to play. If libraries become available to allow bluray playback, the same will be true.

This is what I was pointing out when I linked video lan's new VLC player, it supports bluray via a library provided separately just like libdvdcss is provided separately.

I was never looking for "Out Of The Box" support for blu ray techenicaly Linuxmce doesn't support "Out Of The Box" for encrypted dvd viewing ether. I was only pointing out that video-lan "VLC" has something real close. Much like xine, and mplayer have something real close. The last mentioned players don't play encrypted dvd's with out a special lib that the user must choose to obtain. I'm only asking if the new version of VLC can be implemented in to Linuxmce.. It will be up to the user to obtain the lib for any extra features.

I fail to understand what the difference would be.
Current working option. A player that supports all kinds of files that has an optional lib that the user must obtain.
Proposed working option. A player that supports all kinds of files that has an optional lib that the user must obtain.

Legal comments aside, I completely understand what the legal problem is.
The option I suggest relives Linuxmce of any liability.

thank you for your patience.

Video lan is getting very close to a lib.
http://forum.videolan.org/viewtopic.php?f=5&t=95937
If one of our super uber coders can look into this that would be nice. Just a look, I'm not expecting any work yet.
I know that LMCE has a VLC option instead of xine.
Is this something we can look forward to?
As for the more questionable stuff, can we enable most of what is able to be inabled with out crossing the line and have the user complete the rest on their own. Like how dvdcss is done now.

I know this is old but I see no reason to start a new post.
Has their been any change to this. I would like to set the default option to IMDB for the place to grab metadata form especially for movies and .dvd(i know what they are) files.

Also another side question, I just recovered form a oops and as such I copied all my .dvd's back to my core, is their a one click option to tell Lmce to go get all the metadata for each file on my core and not have to do each one individuality?

OK I'll do that. Unfortunately I don't know how at the moment. I'm currently looking up how to do that now.

Edit..
What's the current state of 10.04? I think I'd rather use it instead of 8.10.
thanks
