[05:00] <conda> What permissions should my video files have for mythtv?
[05:19] <Demerzel> evening folks
[05:20] <Demerzel> quick question
[05:20] <Demerzel> is there a linux parameter that I can give to prevent it from loading any network filesystems in /etc/fstab?
[05:20] <Demerzel> or alternatively is there a way to configure the nic directly from the linux parameters so the network is ready for when i try to mount a network fs?
[05:24] <conda> what exactly are you trying to achieve from this?
[05:25] <conda> does it try to mount your shares before its connected to the network??
[05:46] <conda> for the permissions on my video files is this alright? -rwxrwxr-x 1 mythtv mythtv
[05:48] <chiluk> that sure looks ok.
[05:49] <conda> I cant delete any files through mythvideo
[05:49] <chiluk> the files probably should be executable, but I don't see why that would matter.
[05:50] <chiluk> is 1 the size of your file?
[05:50] <conda> doesnt the x mean that they are executable?
[05:51] <chiluk> sorry I meant they shouldn't be executable.
[05:51] <conda> gotcha
[05:51] <chiluk> mine are all -rw-r--r--  1 chiluk mythtv
[05:51] <chiluk> but I don't try deleting files through mythvideo.
[05:51] <chiluk> you could probably chmod 666 * on that directory
[05:52] <conda> k 1 sec
[05:52] <chiluk> and it will definitely be able to write to to anything.
[05:52] <Demerzel> back
[05:52] <Demerzel> sorry was trying a few things
[05:52] <Demerzel> it was hanging on a cifs mount i'd added to my /etc/fstab
[05:52] <Demerzel> network wasn't ready yet
[05:52] <chiluk> Demerzel ..
[05:53] <chiluk> you could add the noauto option to your mounts in fstab.
[05:53] <Demerzel> true
[05:53] <chiluk> and then edit your ifup scripts.
[05:53] <Demerzel> but i'd still have to manually mount it using rc.local if not ifup
[05:53] <Demerzel> i think i'll switch that fs over to autofs
[05:54] <chiluk> ooh ... snazy.
[05:54] <Demerzel> isn't it though? :)
[05:54] <chiluk> that's a great idea.
[05:54] <Demerzel> in any case the solution to my problem
[05:54] <Demerzel> which was to find a way to edit the fstab file
[05:54] <Demerzel> was interesting
[05:55] <conda> it still says 'failed to delete file'
[05:55] <Demerzel> point to note, i don't have an optical drive in that box
[05:55] <Demerzel> it's my mythbuntu backend server
[05:55] <Demerzel> i edited the grub commandline for the latest "recovery mode" kernel in grub to include "break=mount"
[05:55] <chiluk> conda you may have to scan for changes or otherwise restart the backend before it notices that it can change the files.
[05:55] <chiluk> just a thought..
[05:55] <Demerzel> it breaks just before mounting root
[05:55] <chiluk> as I said... I don't delete stuff.
[05:55] <Demerzel> then i mounted root to /tmp/root in the initramfs
[05:56] <Demerzel> and some clever uses of grep -v later i had an edited fstab file
[05:56] <chiluk> what was preventing you from editing /etc/fstab?
[05:57] <Demerzel> i didn't see an editor in the initramfs
[05:57] <Demerzel> i should've checked for ed
[05:57] <Demerzel> but it's too late
[05:57] <Demerzel> not going back there again
[05:58] <conda> chiluk: cant restart backend right now its recording :)  is there a way to scan for changes?
[05:58] <Demerzel> basically grep was one of the commands available in busybox
[05:58] <chiluk> oh I realized what was going on .. you were hanging on an nfs mount, and didn't want to wait the timeout ..
[05:58] <Demerzel> chiluk: was that for me?
[05:58] <chiluk> conda in myvideo hit m then select scan for changes.
[05:59] <chiluk> yeah demerzel that was for you.
[05:59] <chiluk> or am I incorrect.
[05:59] <Demerzel> chiluk: yeah... except it was a cifs (samba) mount but the issues were the same
[05:59] <Demerzel> not sure what the standard cifs timeout is
[05:59] <chiluk> ok.
[05:59] <chiluk> probably all ugle.
[05:59] <chiluk> s/e/y
[06:03] <Demerzel> https://help.ubuntu.com/community/BootOptions#Initrd%20break%20points
[06:03] <Zinn> [help.ubuntu.com] BootOptions - Community Ubuntu Documentation
[06:03] <Demerzel> that there's a good reference
[06:07] <chiluk> night all ... conda did we fix your issue?
[06:08] <Demerzel> night chiluk
[06:08] <Demerzel> i guess i'll head to bed too
[06:08] <chiluk> I'll assume he's happy since he didn't come back.
[06:08] <Demerzel> tmw should be part 2/3 of the diskless frontend setup on lucid
[06:09] <chiluk> good luck with that.
[06:09] <Demerzel> yeah
[06:09] <chiluk> do you serve the same image to multiple machines?
[06:09] <Demerzel> just the one machine so far
[06:09] <chiluk> ok.
[06:09] <chiluk> I'm curious to see how things go once you add another host.
[06:10] <Demerzel> but tmw is 2/3 of the blog articles about it
[06:10] <chiluk> cool well I'm tired.. good luck.. maybe I'll catch you on again tomorrow.
[06:10] <Demerzel> aight
[06:21] <conda> I just restarted and im still getting 'failed to delete file' in mythvideo
[19:25] <chiluk> very quiet today.
[19:34] <st8ofmi9d> Can I netboot off my mythbuntu backend (9.10) without running DHCP on it?
[19:35] <HeMan> st8ofmi9d: yes
[19:35] <st8ofmi9d> I'm working to run a frontend diskless and I can get it to boot but when I have DHCP runnning on the backend it causes my other hostnames to not resolve themself likely due to a conflict with DHCP running on my DSL router/modem
[19:35] <st8ofmi9d> HeMan: What do I need to do?
[19:36] <HeMan> st8ofmi9d: just use need the package mythbuntu-diskless-server, instead of mythbuntu-diskless-server-standalone
[19:36] <tgm4883> and you need to configure your dhcp server to send pxeboot requests to your mythbuntu system
[19:36] <chiluk> wow that sounds far too easy.
[19:37] <st8ofmi9d> it does sound esay
[19:37]  * tgm4883 hits easy button
[19:38] <tgm4883> chiluk, st8ofmi9d the problem though, is that most home routers don't have the option to send those requests
[19:38] <tgm4883> so you either need to A) haxor your router, or B) set up another system to handle dhcp requests
[19:38] <st8ofmi9d> Any clue on where I would look on my Verizon router/modem to configure pxeboot requests to go to the mythbuntu system?
[19:38] <chiluk> I bet that's why most run dd-wrt
[19:39] <chiluk> or some derivative thereof
[19:39] <tgm4883> chiluk, dd-wrt, openwrt, tomato (maybe)
[19:39] <tgm4883> chiluk, I don't think you mean derivative
[19:39] <tgm4883> as AFAIK none of those are based on dd-wrt
[19:40] <chiluk> oh ok.. I thought they were all forks of the same code-base
[19:40] <chiluk> I can't run em ... d-link dir-655
[19:42] <tgm4883> chiluk, well they all have the linux kernel
[19:42] <chiluk> I definitely knew that.
[19:42] <tgm4883> IIRC, dd-wrt was based on sveasoft's firmware for a while
[19:43] <tgm4883> but those two are usually bad names in open source circles
[19:43] <st8ofmi9d> Would the pxeboot to mythbackend be in the port forwarding section of the router config?
[19:46] <tgm4883> st8ofmi9d, no
[19:46] <tgm4883> sec
[19:46] <tgm4883> hah, I still have it
[19:46] <tgm4883> http://www.dd-wrt.com/phpBB2/viewtopic.php?t=4662&highlight=pxe
[19:46] <Zinn> [www.dd-wrt.com]
[19:47] <tgm4883> that is what I used to set mine up, but I haven't used PXE boot in 2+ years
[19:48] <st8ofmi9d> The Verison DSL router/modem is not DD-WRT compatible.
[19:50] <chiluk> Yeah I would have expected that.
[19:52] <sabhain> tgm4883: that's a great link.  I've used that in the past for diskless .. and am about to again.
[19:53]  * sabhain stunned that Verizon provide hardware isn't self-configurable.  Who knew?
[19:53] <st8ofmi9d> sabhain: I know, shocking isn't it.
[19:54] <st8ofmi9d> I'm guessing that this PoS does not support PXEboot.
[19:55] <mrand> PacketOverSONET has nothing to do with PXE ;-)l
[19:55] <st8ofmi9d> I could take my Asus router (being used as a WAP only) and install tomato on it, btuI'm looking for a more simplified solution using what I already have,
[19:55] <st8ofmi9d> Pos = Piece of Sh1t
[19:55] <st8ofmi9d> :-)
[19:55] <mrand> I'm aware ;-)
[19:56] <st8ofmi9d> I reazied that after I saw the smily
[19:56] <st8ofmi9d> smiley
[19:56] <sabhain> st8ofmi9d: ddwrt routers aren't that pricey .. you might consider controlling your own network by adding a router between the modem and your LAN
[19:56] <tgm4883> sabhain you are the one getting the info together for the MCC plugin?
[19:57] <sabhain> tgm4883: not exactly .. i'm just getting ready to redeploy diskless FE's on a full upgrade / reinstall using 10.04.  Happy to be a tester, but I was planning on doing the manual approach.
[19:57] <mrand> tgm4883: Demerzel, HeMan
[19:57]  * sabhain is pretty sure none of that stuff is written in F90 or F77
[19:58] <tgm4883> mrand, ah thanks
[19:58] <mrand> sabhain: nope, but the some of the same priniciples apply
[19:58] <HeMan> when I tried my newly created image it worked like crap
[19:59] <HeMan> but the problem wasn't my new image but the overlay mount that I had from my 32 bit image...
[19:59] <sabhain> tgm4883: I do have a little-used FE that I'll reserve for doing MCC testing if it will help.  I can afford to monkey with that one to help debug if that type of resource is needed.
[19:59] <HeMan> when I found that it worked fine
[20:00] <sabhain> mrand: for my money and type of projects, F90 still the best number cruncher code I've ever used.  Intrinsic matrix math was a huge leap forward.
[20:02] <mrand> sabhain: I'm not surprised.  I've not used it personally, but heard good things.  I know that f77 is what the super-mini computer companies most easily optimized back in the 80's and 90's, so it makes sense F90 would follow on and expand.
[20:03] <st8ofmi9d> ok, so I can't seem to figure out if my Verizon DSL router/modem supports PXE boot. I looked all over the settings and did some googeling. Can I have the mythbackend only handle DHCP for one or two machines and then have teh router/modem handle the rest?
[20:04] <tgm4883> st8ofmi9d, AFAIK, no
[20:04] <sabhain> mrand: not great for pushing big graphics, though plotting to HPGL was pretty good.  And text & string operations were finicky .. but the pure math of it, which is what I use(d) it for was money.  F90 stripped the fixed formatting requirement off.  Still suported it, but you could freeform as well.
[20:04] <st8ofmi9d> so then I guess I should have the backend handle all DHCP?
[20:05] <tgm4883> yea probably
[20:05] <tgm4883> or get another router
[20:05] <mrand> st8ofmi9d: in general, yes.  I'm guessing there is several ways to have multiple DHCP servers on a segment, but it wasn't really intended originally.
[20:05] <sabhain> st8ofmi9d: you might be able to pull something like that off if you had 2 different subnets .. but I don't know how your clients would know how to get to the right one.  Are you in a wired setup?
[20:06] <mrand> st8ofmi9d: why not just force an IP for one or more things.  For better or worse, I set the IP on my backend to be fixed.
[20:06] <tgm4883> thats my thoughts exactly, how to have the clients contact the right dhcp server
[20:06] <st8ofmi9d> sabhain: I alrady have two subnets. One is for Linux MCE and the other is everything external to LMCE. I'm running myhtbackend on Mythbuntu until I can get LMCE fully up and running.
[20:06] <tgm4883> mrand, how does that solve the issue of pxeboot?
[20:07] <mrand> pxe uses dhcp, doesn't it?
[20:07] <tgm4883> yes
[20:08] <tgm4883> oh wait, are you saying configure the pxeclients to have a static ip and pxe server settings
[20:09] <sabhain> I use the router to set all clients to static IP via DHCP.  Then I use the router to pass the pxe server settings as well
[20:09] <mrand> tgm4883: actually, I was thinking to disable DHCP on the Verizon router and enable it on the server.
[20:09] <tgm4883> ah
[20:09] <tgm4883> i'm just wondering if you could manually tell the client where the server was
[20:10] <sabhain> but the backend definitely has a fixed IP.  How else would I be able to SSH from my nexusone to kick the backend service from my couch?  Gotta know the IP.
[20:10] <tgm4883> and bypass the pxe forwarding crap
[20:10] <tgm4883> sabhain, hostname?
[20:10]  * sabhain prefers the ip i guess
[20:11] <tgm4883> the issue is with routers that don't forward the pxe info
[20:11] <sabhain> tgm4883: plus, the diskless hostnames are MAC addresses (or they were).
[20:12] <st8ofmi9d> sabhain: I can confirm that the backend dhcp is using MAC addresses as hostnames
[20:14] <tgm4883> st8ofmi9d, but can that be fixed?
[20:15] <st8ofmi9d> tgm4883: I'm not sure. I'm just learning as I go.
[20:16] <st8ofmi9d> tgm4883: actually, if the backend DHCP would use hostnames instead of MAC addresses I would simply turn off DHCP on my router/modem
[20:16] <tgm4883> st8ofmi9d, looks like it would need to be set on the dhcp server
[20:16] <tgm4883> according to this http://developer.novell.com/wiki/index.php/HOWTO:_Convert_Ubuntu_to_Diskless
[20:16] <Zinn> [developer.novell.com] HOWTO: Convert Ubuntu to Diskless - Developer Community
[20:21] <tgm4883> actually, I think that is for the server
[20:22] <tgm4883> nope, looks like it was right the first time
[20:22] <tgm4883> http://hydra.geht.net/tino/howto/vmware/pxe/
[20:22] <Zinn> [hydra.geht.net] PXE boot of a guest of VMware server
[20:22]  * tgm4883 goes back to work
[20:26] <st8ofmi9d> should I just manually map all hostnames in /etc/hosts? i've got over a dozen devices so it will be a PITA but it should be a one time thing.
[20:30] <tgm4883> st8ofmi9d, well if you are using your backend as the dhcp server, why not just make the above changes?
[20:32] <st8ofmi9d> tgm4883: which changes do you mean?
[20:35] <st8ofmi9d> tgm4883: Are you talking about http://developer.novell.com/wiki/index.php/HOWTO:_Convert_Ubuntu_to_Diskless#dhcpd_and_atftp
[20:35] <Zinn> [developer.novell.com] HOWTO: Convert Ubuntu to Diskless - Developer Community
[20:35] <st8ofmi9d> and I shoudl list each host in teh dhcpd.conf?
[20:43] <tgm4883> st8ofmi9d, something like that, I haven't set it up in awhile, but that looks like itmight help
[22:52] <lapion> Hi I am running mythtv version 24158 (0.23-fixes)  on lucid lynx API: 0.23.20100314-1 and it can't sca for channels on my anal;og card, nor my dvb-t cards
[22:52] <lapion> *card\
[23:00] <lapion> ok nvm.. it's a littlebit complicated..
[23:00] <lapion> they should give some info when you have not set up everything to be able to scan channels
[23:03] <liminal> hello
[23:03] <liminal> ive installed mythtv sucessfully in ubuntu lucid
[23:03] <liminal> but when im watching tv every now again it randomly crashes
[23:04] <liminal> i can't figure out what any possible cause might be
[23:04] <liminal> are there some lovely logs?
[23:04] <tgm4883> !logs
[23:04] <Zinn> MythTV logs are stored in /var/log/mythtv/   You can use mythbuntu-log-grabber from the Applications menu to automatically post the most relevant logs to our pastebin.
[23:05] <tgm4883> liminal, you want the backend logs, if you use mythbuntu-log-grabber, you will need to manually paste the logs that are in /tmp/mythbuntu-logs (I think thats the filename)
[23:05] <tgm4883> and use
[23:05] <tgm4883> !pastebin
[23:05] <Zinn> when pasting more than 5 lines of data please use http://mythbuntu.pastebin.com so you don't flood the channel.  Then please post the link in the channel.
[23:05] <tgm4883> lapion, I agree, they should
[23:06] <lapion> liminal, what vgz-chipset does the system have ?
[23:06] <lapion> *vga
[23:08] <liminal> vgz?
[23:08] <liminal> video graphic card|
[23:08] <liminal> ?
[23:09] <liminal> oh vga
[23:09] <tgm4883> liminal, yea
[23:09] <liminal> its ati
[23:09] <tgm4883> what kind?
[23:09] <liminal> hd 2600xt
[23:09] <liminal> i think
[23:09] <liminal> it just crashed again the last line in the logs are timed out wating for free video buffers
[23:10] <liminal> but yes.. i suspect its video card/driver related
[23:11] <lapion> lucid lynx has some problems with ati
[23:11] <liminal> no its not lucid
[23:11] <liminal> i had exactly the same problems with karmic
[23:11] <mrand> might need to add -v playback,important,general to get more any more info.  Also, it might be helpful to run it from within gdb after installing the mythtv-dbg and mythplugins-dbg packages to capture a backtrack.
[23:11] <liminal> thats why i upgraded
[23:12] <liminal> its actually better with lucid than with karmic
[23:13] <mrand> although if it is ati driver related, maybe the -dbg and gdb stuff won't help.
[23:20] <lapion> liminal karmic and lucid both use kms..
[23:20] <lapion> go figure
[23:21] <lapion> Why can't I do a full scan of the whole bandwidth for dvb-t
[23:25] <mrand> Sorry, for any and all scan questions, I defer to #mythtv-users, or their wiki or mailing list.
[23:30] <lapion> why do I have to select a country when I want to do a full-scan.. in me-tv I don't
[23:31] <mrand> lapion: myth has frequency tables that it uses I think.  I don't know anything more than that (like why me-tv doesn't ask, or if they do it completely differently).
[23:32] <tgm4883> myth uses dvb frequency tables
[23:32] <tgm4883> i"m not sure if me-tv does
[23:42] <liminal> what is kms?
[23:44] <bollyman> To use the livecd, what exactly is a "backend"?
[23:46] <mrand> bollyman: backend is the device which is connected to houses the video input/capture device (commonly called a tuner).
[23:46] <chiluk> mythtv is divided into a frontend that displays the video, and a backend that is responsible for recording and storing the video.
[23:46] <chiluk> both can be on the same machine.
[23:47] <chiluk> I wish I could continue, but I need to git.
[23:58] <bollyman> can the backend be run from the livecd?
