[05:00] What permissions should my video files have for mythtv? === Guest48926 is now known as cmug [05:19] evening folks [05:20] quick question [05:20] is there a linux parameter that I can give to prevent it from loading any network filesystems in /etc/fstab? [05:20] 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] what exactly are you trying to achieve from this? [05:25] does it try to mount your shares before its connected to the network?? [05:46] for the permissions on my video files is this alright? -rwxrwxr-x 1 mythtv mythtv [05:48] that sure looks ok. [05:49] I cant delete any files through mythvideo [05:49] the files probably should be executable, but I don't see why that would matter. [05:50] is 1 the size of your file? [05:50] doesnt the x mean that they are executable? [05:51] sorry I meant they shouldn't be executable. [05:51] gotcha [05:51] mine are all -rw-r--r-- 1 chiluk mythtv [05:51] but I don't try deleting files through mythvideo. [05:51] you could probably chmod 666 * on that directory [05:52] k 1 sec [05:52] and it will definitely be able to write to to anything. [05:52] back [05:52] sorry was trying a few things [05:52] it was hanging on a cifs mount i'd added to my /etc/fstab [05:52] network wasn't ready yet [05:52] Demerzel .. [05:53] you could add the noauto option to your mounts in fstab. [05:53] true [05:53] and then edit your ifup scripts. [05:53] but i'd still have to manually mount it using rc.local if not ifup [05:53] i think i'll switch that fs over to autofs [05:54] ooh ... snazy. [05:54] isn't it though? :) [05:54] that's a great idea. [05:54] in any case the solution to my problem [05:54] which was to find a way to edit the fstab file [05:54] was interesting [05:55] it still says 'failed to delete file' [05:55] point to note, i don't have an optical drive in that box [05:55] it's my mythbuntu backend server [05:55] i edited the grub commandline for the latest "recovery mode" kernel in grub to include "break=mount" [05:55] conda you may have to scan for changes or otherwise restart the backend before it notices that it can change the files. [05:55] just a thought.. [05:55] it breaks just before mounting root [05:55] as I said... I don't delete stuff. [05:55] then i mounted root to /tmp/root in the initramfs [05:56] and some clever uses of grep -v later i had an edited fstab file [05:56] what was preventing you from editing /etc/fstab? [05:57] i didn't see an editor in the initramfs [05:57] i should've checked for ed [05:57] but it's too late [05:57] not going back there again [05:58] chiluk: cant restart backend right now its recording :) is there a way to scan for changes? [05:58] basically grep was one of the commands available in busybox [05:58] oh I realized what was going on .. you were hanging on an nfs mount, and didn't want to wait the timeout .. [05:58] chiluk: was that for me? [05:58] conda in myvideo hit m then select scan for changes. [05:59] yeah demerzel that was for you. [05:59] or am I incorrect. [05:59] chiluk: yeah... except it was a cifs (samba) mount but the issues were the same [05:59] not sure what the standard cifs timeout is [05:59] ok. [05:59] probably all ugle. [05:59] s/e/y [06:03] https://help.ubuntu.com/community/BootOptions#Initrd%20break%20points [06:03] [help.ubuntu.com] BootOptions - Community Ubuntu Documentation [06:03] that there's a good reference [06:07] night all ... conda did we fix your issue? [06:08] night chiluk [06:08] i guess i'll head to bed too [06:08] I'll assume he's happy since he didn't come back. [06:08] tmw should be part 2/3 of the diskless frontend setup on lucid [06:09] good luck with that. [06:09] yeah [06:09] do you serve the same image to multiple machines? [06:09] just the one machine so far [06:09] ok. [06:09] I'm curious to see how things go once you add another host. [06:10] but tmw is 2/3 of the blog articles about it [06:10] cool well I'm tired.. good luck.. maybe I'll catch you on again tomorrow. [06:10] aight [06:21] I just restarted and im still getting 'failed to delete file' in mythvideo [19:25] very quiet today. [19:34] Can I netboot off my mythbuntu backend (9.10) without running DHCP on it? [19:35] st8ofmi9d: yes [19:35] 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] HeMan: What do I need to do? [19:36] st8ofmi9d: just use need the package mythbuntu-diskless-server, instead of mythbuntu-diskless-server-standalone [19:36] and you need to configure your dhcp server to send pxeboot requests to your mythbuntu system [19:36] wow that sounds far too easy. [19:37] it does sound esay [19:37] * tgm4883 hits easy button [19:38] chiluk, st8ofmi9d the problem though, is that most home routers don't have the option to send those requests [19:38] so you either need to A) haxor your router, or B) set up another system to handle dhcp requests [19:38] Any clue on where I would look on my Verizon router/modem to configure pxeboot requests to go to the mythbuntu system? [19:38] I bet that's why most run dd-wrt [19:39] or some derivative thereof [19:39] chiluk, dd-wrt, openwrt, tomato (maybe) [19:39] chiluk, I don't think you mean derivative [19:39] as AFAIK none of those are based on dd-wrt [19:40] oh ok.. I thought they were all forks of the same code-base [19:40] I can't run em ... d-link dir-655 [19:42] chiluk, well they all have the linux kernel [19:42] I definitely knew that. [19:42] IIRC, dd-wrt was based on sveasoft's firmware for a while [19:43] but those two are usually bad names in open source circles [19:43] Would the pxeboot to mythbackend be in the port forwarding section of the router config? [19:46] st8ofmi9d, no [19:46] sec [19:46] hah, I still have it [19:46] http://www.dd-wrt.com/phpBB2/viewtopic.php?t=4662&highlight=pxe [19:46] [www.dd-wrt.com] [19:47] that is what I used to set mine up, but I haven't used PXE boot in 2+ years [19:48] The Verison DSL router/modem is not DD-WRT compatible. [19:50] Yeah I would have expected that. [19:52] 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] sabhain: I know, shocking isn't it. [19:54] I'm guessing that this PoS does not support PXEboot. [19:55] PacketOverSONET has nothing to do with PXE ;-)l [19:55] 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] Pos = Piece of Sh1t [19:55] :-) [19:55] I'm aware ;-) [19:56] I reazied that after I saw the smily [19:56] smiley [19:56] 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] sabhain you are the one getting the info together for the MCC plugin? [19:57] 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] tgm4883: Demerzel, HeMan [19:57] * sabhain is pretty sure none of that stuff is written in F90 or F77 [19:58] mrand, ah thanks [19:58] sabhain: nope, but the some of the same priniciples apply [19:58] when I tried my newly created image it worked like crap [19:59] but the problem wasn't my new image but the overlay mount that I had from my 32 bit image... [19:59] 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] when I found that it worked fine [20:00] 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] 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] 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] st8ofmi9d, AFAIK, no [20:04] 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] so then I guess I should have the backend handle all DHCP? [20:05] yea probably [20:05] or get another router [20:05] 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] 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] 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] thats my thoughts exactly, how to have the clients contact the right dhcp server [20:06] 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] mrand, how does that solve the issue of pxeboot? [20:07] pxe uses dhcp, doesn't it? [20:07] yes [20:08] oh wait, are you saying configure the pxeclients to have a static ip and pxe server settings [20:09] 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] tgm4883: actually, I was thinking to disable DHCP on the Verizon router and enable it on the server. [20:09] ah [20:09] i'm just wondering if you could manually tell the client where the server was [20:10] 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] and bypass the pxe forwarding crap [20:10] sabhain, hostname? [20:10] * sabhain prefers the ip i guess [20:11] the issue is with routers that don't forward the pxe info [20:11] tgm4883: plus, the diskless hostnames are MAC addresses (or they were). [20:12] sabhain: I can confirm that the backend dhcp is using MAC addresses as hostnames [20:14] st8ofmi9d, but can that be fixed? [20:15] tgm4883: I'm not sure. I'm just learning as I go. [20:16] 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] st8ofmi9d, looks like it would need to be set on the dhcp server [20:16] according to this http://developer.novell.com/wiki/index.php/HOWTO:_Convert_Ubuntu_to_Diskless [20:16] [developer.novell.com] HOWTO: Convert Ubuntu to Diskless - Developer Community [20:21] actually, I think that is for the server [20:22] nope, looks like it was right the first time [20:22] http://hydra.geht.net/tino/howto/vmware/pxe/ [20:22] [hydra.geht.net] PXE boot of a guest of VMware server [20:22] * tgm4883 goes back to work [20:26] 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] st8ofmi9d, well if you are using your backend as the dhcp server, why not just make the above changes? [20:32] tgm4883: which changes do you mean? [20:35] tgm4883: Are you talking about http://developer.novell.com/wiki/index.php/HOWTO:_Convert_Ubuntu_to_Diskless#dhcpd_and_atftp [20:35] [developer.novell.com] HOWTO: Convert Ubuntu to Diskless - Developer Community [20:35] and I shoudl list each host in teh dhcpd.conf? [20:43] st8ofmi9d, something like that, I haven't set it up in awhile, but that looks like itmight help [22:52] 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] *card\ [23:00] ok nvm.. it's a littlebit complicated.. [23:00] they should give some info when you have not set up everything to be able to scan channels [23:03] hello [23:03] ive installed mythtv sucessfully in ubuntu lucid [23:03] but when im watching tv every now again it randomly crashes [23:04] i can't figure out what any possible cause might be [23:04] are there some lovely logs? [23:04] !logs [23:04] 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] 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] and use [23:05] !pastebin [23:05] 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] lapion, I agree, they should [23:06] liminal, what vgz-chipset does the system have ? [23:06] *vga [23:08] vgz? [23:08] video graphic card| [23:08] ? [23:09] oh vga [23:09] liminal, yea [23:09] its ati [23:09] what kind? [23:09] hd 2600xt [23:09] i think [23:09] it just crashed again the last line in the logs are timed out wating for free video buffers [23:10] but yes.. i suspect its video card/driver related [23:11] lucid lynx has some problems with ati [23:11] no its not lucid [23:11] i had exactly the same problems with karmic [23:11] 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] thats why i upgraded [23:12] its actually better with lucid than with karmic [23:13] although if it is ati driver related, maybe the -dbg and gdb stuff won't help. [23:20] liminal karmic and lucid both use kms.. [23:20] go figure [23:21] Why can't I do a full scan of the whole bandwidth for dvb-t [23:25] Sorry, for any and all scan questions, I defer to #mythtv-users, or their wiki or mailing list. [23:30] why do I have to select a country when I want to do a full-scan.. in me-tv I don't [23:31] 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] myth uses dvb frequency tables [23:32] i"m not sure if me-tv does [23:42] what is kms? [23:44] To use the livecd, what exactly is a "backend"? [23:46] bollyman: backend is the device which is connected to houses the video input/capture device (commonly called a tuner). [23:46] mythtv is divided into a frontend that displays the video, and a backend that is responsible for recording and storing the video. [23:46] both can be on the same machine. [23:47] I wish I could continue, but I need to git. [23:58] can the backend be run from the livecd?
