A good thing would be a small linux system that boots linux and runs boinc in ramdisk, so that no harddrive is needed. Save the wu's and boinc settins on a sub stick or something. So that a reboot could be easily done without re-setting everything (or even copy the stick to run many other pc's) |

So that a reboot could be easily done without re-setting everything (or even copy the stick to run many other pc's) There is a linux diskless project, which has a package for setup a diskless linux client. It would be save the complete BOINC directory to a USB stick or a network drive. But I am not shure if it is a good idea, to transfer the WUs with a USB stick, because a lot of things are stored in the xml files. So I would prefer so save the complete BOINC directory on a network drive or an USB stick. If you would make it save, you can setup a proxy server on the server (where your clients get the boot images) and setup the server with a external LAN and a internal LAN, where the diskless clients are connected. The diskless clients connecting over the proxy server to the seti server, but have no network connection. |

I have already started to write some scripts for slax. It runs from a 200mb cd or usbstick. the scripts will hopefully create a ramdisk for seti, and when shutting down it stores the seti ramdisk on the usbstick.... |

It runs from a 200mb cd or usbstick. the scripts will hopefully create a ramdisk for seti, and when shutting down it stores the seti ramdisk on the usbstick.... I see the some problems with the ramdisk... On a power outage, crash or reboot of the system the entire data will be lost. So it would the best, to create a backup script which make a periodical backup (for example every hour) of the whole BOINC directory to the USB stick. Also, I think booting from the network and storing or backuping the BOINC directories of the diskless clients on a network share (NFS) would be the safest and practical method. But if you store directly to the network shares and your fileserver crash, your diskless clients will stop. If you make a backup script and copy data from the ramdisk to the NFS share, would not harm the diskless clients, if the fileserver crashs or reboots. |

Okay, didn't expect a client to crash :-)) but thats a good thing to think about! how would a backup look like? -> stop boinc, save files and then start boinc again; or can I just copy the files while seti works with them? (Dont know how file access etc is implemented in seti and boinc) I think I would rather save every 3 or 4 hours as a usb stick is flash... Running diskless saves a lot of HDD power consumption... My file server spins down the disks as I never use them while Iam asleep or @ work, so I dont want to store to the nfs share periodically (of course thats only for my case). |

Okay, didn't expect a client to crash :-)) but thats a good thing to think about! I have made a script which backups, when the boinc client is running. I had never any problems, and the restore worked, too. But I think it is no problem to backup online, because SETI writes every 60 seconds some KBs.
It is a good idea, to save energy. |

There are 'Live' versions of Linux that can run off a cd/dvd and not install themselves to the harddrive, but I am not sure how you would get Seti to run if you couldn't install it. There are discussion elsewhere on these boards about findng a Linux Distro with Boinc built in. I have not seen where they have actually found one yet though. You could go here and scroll thru all the different versions and look though http://www.linuxlinks.com/Distributions/ ![]() |
