Installation issues / 12.04 Client Machines Can't Browse Some Websites
« on: August 27, 2014, 04:38:32 pm »
I have my old 10.04 server and a new 12.04 server that I've assembled and am testing (vanilla install, no modifications yet).

I have a win7 client and a win8 client. Both are having intermittent problems accessing certain websites via the new 12.04 core. Specifically, * (and likely others I just haven't tested thoroughly yet)
  • On the win7 machine, Chrome reports ERR_EMPTY_RESPONSE. Several refreshes and the page will usually load. I tried the same pages in IE and they also don't load but IE gives no useful debugging info.
  • On the win8 machine, Chrome reports ERR_CONNECTION_RESET for these pages.
  • These errors are thrown instantly. There is no time-out.
  • My android phone can access these sites reliably via Chrome.
  • I have no issues with web access on any client with the same configuration through the 10.04 server.
Anyone encountered anything like this or have suggestions to narrow down the issue? I've cleared the browser cache of all my browsers, restarted machines, etc to no avail.

EDIT: Found this which sounds like a similar symptom but I'm not on pppoe so not sure yet how or if this applies

Installation issues / Re: 12.04 NAT Port Forwarding Issue
« on: August 14, 2014, 08:05:03 pm »
can you get  me the output of: iptables -vnL (with sudo).
here i can see of the forward rule  is created.
It's not. I'll have to wait till I get home to get you the output of that command, but I did run it last night and noticed that the forward rule was missing. When created the forward rule manually via the iptables command from my last post, it started working.

Shows up in iptables now:

But still doesn't seem to forward traffic.

I got it working manually in iptables using

Code: [Select]
iptables -t nat -A PREROUTING -p tcp --dport 33892 -j DNAT --to
iptables -A FORWARD -p tcp -d --dport 3389 -j ACCEPT

Seems that the required FORWARD chain rule does not get created (even though it is created in webadmin). Also seems that

    1    60 DNAT       tcp  --  *      *              tcp dpt:3389 to:

should be

    1    60 DNAT       tcp  --  *      *              tcp dpt:33892 to:

Installation issues / 1204 MythTV - Can't Configure HDHomerun
« on: August 12, 2014, 05:14:05 pm »
On a fresh 1204 DVD install, my tuners are correctly detected and corresponding devices created in LMCE.  In MythTV setup, I can do a channel scan and the expected channels are detected, so communication with tuner appears to be working.

In MythTV setup under "Input Connections" the tuners are not assigned a video source by default. I can manually map this connection, exit the setup, reload router, but the setting does not persist.

Trying to watch live TV, I'm given the error that no tuners are available.
This exact same hardware setup works normally under 1004.

I created a ticket here:

Did you try it anyway?

Yes, sorry, I should have said.

Shouldn't you put some source port definition in there?

Not according to Alblasco's instructions:

Port forwarding doesn't seem to be working, or I'm not understanding how to configure it in webadmin.

Alblasco, you requested this on IRC but I wasn't around.


Code: [Select]
iptables -t nat -vnL

I can confirm that disabling ipv6 solved my issue in LMCE 1204.

I may have fixed this by disabling ipv6 and removing "dns=dnsmasq" (not sure what this does) from vanilla Kubuntu 12.04 as per this post:

I've confirmed this issue exists for me in vanilla Kubuntu 12.04, so it seems independent of LMCE code.

I will take my problem to other forums - thanks to everyone who's offered help so far.

My NICs incase anyone runs into this:

From the video end, this is a good resource:

I'm not sure, but likely haswell is not supported in 1004 either. I think the goal with 1204 is to support more of the small form factor and power efficient mini pcs (like intel NUC).

I've asked the same question as you in the past and never received a clear answer or recommendation.  Ultimately I found it best to buy the same hardware that the devs have (they often discuss in the wiki, forums, on IRC, etc). You still run into the odd issue but it is far easier to get a fix when they can reproduce bugs at their end.

On the other hand, they'd of course be happy to have you buy something different so you can contribute by making LMCE compatible with a larger hardware base :)

Installation issues / Re: 12.04 - firewall issues?
« on: August 06, 2014, 04:23:33 am »
I applied the updated files supplied by Alblasco. (from reply #9) to /usr/pluto/bin/ (replacing original)
firewall.php (from reply #5) to /var/www/lmce-admin/operations/network/firewall.php (replacing original)

Rebooted core.

still unable to 'ping' an internet web page by name or address from the core OR a workstation getting IP from the core.

can anyone else confirm?


Alblasco's updated scripts worked for me, after a rule reset. I'm not an "IDIOT" but clicking that button did help matters :P

I'd like to see if I can figure out if this is an issue specific to kubuntu 1204 and my hardware and if it is independent of LinuxMCE. I'm going to try the following:

* Install Kubuntu 1204 desktop (w/no LinuxMCE)
* Configure NAT using something like
* Verify if problem still exists.

If the problem disappears then I guess it's something specific to the LMCE implementation of NAT.
