[SLUG] auto get file out of email to folder then act on it
Hi all, So far I have not found a solution in Google but maybe I'm not looking for the correct thing...? A client of mine is getting a .zip file every day to his redhat postfix inbox. I need to automatically get the zip file from the email and put it in a folder on another machine, then unzip it, then run a program on the extracted file. There are probably a few pieces to this puzzle. Is there such an animal that can auto extract a known email? (known from address, known file name) What about auto moving it to another computer? Also another utility that can launch a program on detecting a file arriving in a folder? (if a large file it would have to wait till it was all there I suppose) Any pointers in the right direction would be appreciated.

I need to automatically get the zip file from the email and put it in a folder on another machine, then unzip it, then run a program on the extracted file. General ideas on how I'd tackle such a task: 1. procmail to scan each incoming e-mail for the message you want to process, then extracts the mail and runs the rest. 2. A script to scp the extracted attachment to the other machine using a limited-access, no passphrase-protected, dedicated ssh key (limited on the server side using the command= parameter in .ssh/authorized_keys on the remote side - see man sshd section on AUTHORIZED_KEYS FILE FORMAT. 3. Instead of scp you can also run something on the remote side which will accept the file over the ssh connection, dump it into the remote file then execute something else when the file is done. 4. Another option is to scp with one key then use another ssh key to trigger a script to process the file remotely.

It's going to be inside a cabinet so doesn't have to be stunningly beautiful, but I don't want it to look spectacularly ugly either. My budget is $2000. you probably want a silverstone case. They have some nice ones. I have one with a buttload of fans in it and its still quieter than the fish tank. I want HDMI video to the TV (LCD, 1080p), either with audio or with a separate analogue audio cable. I also want digital audio (S/PDIF, preferrably coax) to the amp for better quality stereo or 5.1 audio. I haven't played with the audio side much yet so I cant help you too much there. I'd also like the option of watching either live TV, recorded programs or ripped DVDs on any other PC on the LAN, at the same time as a different program is being watched on the TV and maybe another is being recorded. Myth will do that provided your not on a wireless network. ripped dvd's etc will need to be shared over NFS or something as mythvideo doesn't use the backend to pass the files around. you can run mythfrontend on the remote sites and it'll pick up the recorded tv though. I believe that all of the hardware I'm thinking of is supported by Linux and MythTV, and although I don't think the necessary drivers are packaged in any distro yet (I'm thinking of using the latest Mythbuntu, only because everything else is running Ubuntu), I do know where to get them. This is my list of hardware: Asus P5Q SE2 motherboard Intel Core2Duo E7600 3.06GHz 1066MHz FSB 2GB PC6400 DDR2 RAM Asus GeForce GT220 1GB DDR3 video card 1.5GB Seagate 7200 RPM SATA HDD (ST31500341AS) Lite-On SATA 240x8 DVD-RW drive Silverstone LC10-E case 500W power supply Logitech diNovo Mini bluetooth keyboard Suggestions specifically. If you want quiet, ditch the mbo, cpu and separate video card. the new myth out uses vdpau to accelerate video on anything that supports it ( nvidia 9300 or so) I am running an asus P5N7A-VM which has onboard 9300, HDMI, optical spdif etc. Except for commercial flagging the atom based ion boards would do nicely, If you run the commflagging over night then one of those (especially a dual core) would probably do the whole job. I have a quad core q6600 in it but I'd put one of the newer quad cores in it now but its also my everything server (it has 6gb of ram and is running 5 virtual machines). keep the clock speed down and it'll keep the temps down. You could probably get away with a generic dual core. Although if you want to run commercial flagging while recording you will probably want one cpu per channel. I wonder when VDPAU/CUDA enhanced commflagging will come out ;- CPU load watching HDTV is ~5% or so with VDPAU doing all the work. It cant *quite* manage advanced 2x deinterlacing for HD footage, I overclocked it to 9400 speed as well with no change. So if you really really want to then perhaps an external card. They are typically really noisy though (relatively speaking). The blue-ray's I have managed to watch @#...@#%@#$%$%^%(^%^$# DRM!!! GRRR! have played fine on it again at 5% cpu for a 1080P movie (twilight). and either of: Hauppage Nova-T-500 MCE dual tuner (PCI) Hauppage 2200 MCE dual tuner (PCI-E) That's where your going to have the difficulties with drivers, I haven't looked but I'm not aware as yet of any PCI-E cards that are supported as yet out of the box. There was a twin digital PCI-E tuner floating about with drivers real soon now as I recall. I'll probably add a second tuner card once I've got it all up and running. We have occasionally wished for a third tuner in the past (not often, there's not that much worth watching on TV), so I may as well have four, just in case :-) I'm thinking of getting some cheap USB tuners from deal extreme or similar, the people over on the shepherd list (the TV guide you will use) have had some good and some bad experiences with them. Is this hardware powerful enough to do all that I want? Do I need more CPU grunt? More RAM? More hard drives? Bigger PSU? Anything else? Way too much CPU ;- Add another hdd or 2 because myth can use storage pools to reduce the seek load when recording and playing multiple streams and drives are so cheap these days. I'd investigate the possibility of sticking / on a USB stick perhaps so that the spinning disks can shut down. Not a big deal in a decent case, I have 4 or 5 drives in mine and I don't notice them. The only other thing I can think of is remote control.

Re: [SLUG] *buntu won't start X

I haven't tried it again with the original RAM in yet though. Basically the machine works fine with XP, *buntu 9.04, Slitaz, parted magic, TRK, and a bunch of other distros, but any *buntu 9.10 just won't work. I'm trying to get MythBuntu 9.10 on there but it's been oddly difficult. Yeah my BIOS has a basic GUI like most others, there's no mouse in BIOS but I considered that normal. The Motherboard (K8NS-Ultra 939) doesn't have any on board video that could be interfering but i'll see if I can tweak any video settings in BIOS anyway. There's probably AGP settings there to fiddle with i guess. I could pick up an old AGP Nvidia card off ebay if all else fails - I don't know maybe i could try an alternate install too?

I am fairly newbish with iptables. Andrew Bootsma So I think you're saying you've got a virtual machine on qtap0 inside a physical machine with for argument's sake eth0 as it's physical interface. Is this what you're saying? Or is qtap0 something like an ethernet going to some other internal LAN? Doesn't matter greatly for this discussion. [LAN/WAN/Internet?] | | [[eth0 x.x.x.x] [ | [ | [[qtap0] 213.133.127.y] [ [physical machine] Firstly... `cat /proc/sys/net/ipv4/ip_forward` should result in '1' being displayed. If not you need to adjust your /etc/sysctl.conf and then reload it with `sysctl -p`. This is the master switch that says your host is actually a router as well. Secondly, and I suppose you've already done this, check that you can ping the virtual from the host and that you can ping the host from the virtual. If not, get that working first. Next if the outside world has an appropriate route to your subnet (it appears to) that's great. If not you'll have to NAT it's traffic coming out of eth0 with something like `iptables -t nat -A POSTROUTING -s 213.133.127.0/29 -j MASQUERADE` which will translate everything to your x.x.x.x address somewhat defeat the purpose of the /29 net but it'll work. Next failing that you'll have to supply more information like what x.x.x.x is, your routing table, your iptables setup. `iptables -t filter -L -n -v` and `iptables -t nat -L -n -v` and some examples of the output of tcpdump on eth0 and qtap0 concurrently. EG `tcpdump -n -i eth0 icmp` in one terminal and `tcpdump -n -i qtap0 icmp` in another terminal. Then pings from your virtual machine to a known IP address (avoiding DNS lookup). -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

[SLUG] workspace switcher names not saving
On my Ubuntu 8.10 laptop I can set the names of the 8 workspaces I use by right clicking and selecting preferences. Apparently this is dependent on not having Compiz and among other things the video card driver, in my case Nvidia. The names of the workspaces only appear to last as long as the session does. They survive a suspend and resume ok but logging out and logging back in changes them back to the default of Workspace 1 Workspace 2 ... etc. I should point out that it DOES save my preference for the number of workspaces and the number of rows they appear in. For now my workaround is going by memory... ie Workspace 2 is my web window, workspace 1 is my mail window. Has anyone else had this experience and/or found a workaround? Does it happen in 9.04? Does it happen in Fedora 11? -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

adding custom entries (/etc/grub.d/40_custom) if i'm understanding
everything right.
It might be good to have a sluglet or some kinda talk about Grub 2 at an

I already have both NFS and Samba running on other machines. you can run mythfrontend on the remote sites and it'll pick up the recorded tv though. That's what I'd figured, but it's nice to have it confirmed. Suggestions specifically. If you want quiet, ditch the mbo, cpu and separate video card. the new myth out uses vdpau to accelerate video on anything that supports it ( nvidia 9300 or so) The card I'd picked, the GT220, supports VDPAU (VP4 including MPEG-4 decoding), but I'll have another look at motherboards and see if I can find one with suitable graphics on-board. I have a quad core q6600 in it but I'd put one of the newer quad cores in it now but its also my everything server (it has 6gb of ram and is This is going to be running MythTV only, so I figured a dual core would be enough. Although if you want to run commercial flagging while recording you will probably want one cpu per channel. We can live without that. We're used to skipping ads manually, so as long as I can configure a 30-sec skip button on the remote, it'll be fine. CPU load watching HDTV is ~5% or so with VDPAU doing all the work. It That should keep the noise down :-) cant *quite* manage advanced 2x deinterlacing for HD footage, I overclocked it to 9400 speed as well with no change. So if you really Wikipedia says that the GT220 is more powerful than the 9400, so it might be able to handle it. There's also the GT240 (rumoured to be coming soon), which has even more grunt. The blue-ray's I have managed to watch @#...@#%@#$%$%^%(^%^$# DRM!!! GRRR! have played fine on it again at 5% cpu for a 1080P movie (twilight). OK. I hadn't thought much about Blu-Ray yet. I agree with you about the DRM though. Hauppage 2200 MCE dual tuner (PCI-E) That's where your going to have the difficulties with drivers, I haven't looked but I'm not aware as yet of any PCI-E cards that are supported as yet out of the box. Not out of the box, but there is a driver for the 2200: http://www.kernellabs.com/blog/?page_id=17 http://www.mythtv.org/pipermail/mythtv-users/2009-October/266154.html There was a twin digital PCI-E tuner floating about with drivers real soon now as I recall. That might have been the 2200/2250. I'm thinking of getting some cheap USB tuners from deal extreme or similar, the people over on the shepherd list (the TV guide you will use) have had some good and some bad experiences with them. I have an AverMedia USB tuner, which does have Linux drivers, but they're not very good. The tuner works the first time I plug it into my laptop, but if I remove it I have to reboot to use it again. It also occasionally causes the laptop to hang (needing a power reset) when it's plugged in. Is this hardware powerful enough to do all that I want? Do I need more CPU grunt? More RAM? More hard drives? Bigger PSU? Anything else? Way too much CPU ;- Too much CPU is barely enough :-) Add another hdd or 2 because myth can use storage pools to reduce the seek load when recording and playing multiple streams and drives are so cheap these days. More drives == more noise though, so if I do add more drives, maybe I should configure a remote back-end? The machine I'd do that on would then need some drives replacing because all of its SATA ports are in use, and there's not enough free space to store much TV. I'd investigate the possibility of sticking / on a USB stick perhaps so that the spinning disks can shut down. I'd thought of that too, but I'll get it up and running on a hard drive first and see how much noise it makes. Our analogue hard drive recorder is barely audible with the cabinet door closed. We can hear the drive heads moving sometimes, but only when editing or deleting
