Hmm... Sorry it didn't work out Ok. Looking at the Xandros site I wonder just how much they've tweaked Linux for their distribution - they do seem pretty determined to hide lots of stuff from the user. Someone has already posted your question on their forum - maybe you? ;) (no answer posted) - and I wonder if that might be a better place to try first. At least if there are difficulties being caused by Xandros-specific tweaks (maybe the shell variables are set in a different file, or protected from being changed by a user for safety reasons?), that forum should be able to give better help than me for the Xandros parts. That said, if there is anything in what I posted earlier which wasn't very clear, puzzled you or just gave unexpected results (er, apart from just not setting the variable!) then please feel free to post more questions here. |

From a console, logged on as the user who would run BOINC, add the following line to your .bashrc file (normally in that user's home directory): export BROWSER=/usr/bin/firefox You can make sure that path is correct by first doing: which firefox to find it on the path and use that instead. Obviously, substitute your browser name for firefox if required. ;) Log out, then log in again. Doing: echo $BROWSER should return /usr/bin/firefox Note that this variable won't yet be available on any currently open shell because they will be using the environment variables as they were when that instance of the shell was started. They've been changed since then so those shells will need to be restarted too. If you've installed BOINC as root and are changing the environment variable for your normal user logon - that won't work as expected when running BOINC. Best solution there is to install BOINC under your normal, non-privileged user logon and modify that .bashrc, and not do any BOINC-related stuff as root. All of the above assumes you're using 'bash' (many/most do - AFAIK doing: echo $SHELL is pretty standard and would show what's in use), and that the distro hasn't done anything "tricky" with the way that bash works. |

Unix/Linux :
Linux distro for SETI
(消息 533415)
发表于：18 Mar 2007 作者： Bryn Post: I asked if there was a distro of Linux specifically designed to run only BOINC. There isn't, since the requirements of BOINC are what would be required to run lots of other Linux-based software too. But you could probably make one from DSL or Knoppix by stripping out everything which makes Linux generally useful, leaving only what's specifically useful with BOINC. Just curious: why would you want to do this anyway? |

It's a server problem with setiathome - i have the same errors reported too. These things are generally very temporary so hang fire for a while, just leave BOINC running as usual and it will get sorted out soon enough. |

Unix/Linux :

(消息 516277)
发表于：11 Feb 2007 作者： Bryn Post: When I did try to open the CFG file I was told I did not have the required permission. Plus I have TWO copies of this file, probably due to repeated problems trying to install the BOINCxxx.sh file. This implies that you may be looking, as a non-privileged user, at an installation which was done as root and if so, you won't be allowed to edit it. This is the correct state. (Also, you may well have a couple of dud installations but they can be ignored for now - the worst that'll happen is a little disk space is wasted and that can be recovered later once everything's running.) Don't install BOINC as root: it's not necessary and could potentially be insecure. Get used to the Unix way which is that nothing, but nothing is done as root unless it's a privileged operation that root should be doing. (and there are very few instances where this may be true) Instead, you should log on as "yourself" (ie. an ordinary non-privileged user) and install BOINC without using any bizzare, Ubuntu-specific gizmos or GUI systems. It seems to me that these are the cause of many/most install problems here. Get the standard seti BOINCxxx.sh package and make sure it's in your ordinary, non-privileged user's home directory, make sure you're in that directory as that user, and then just type (yes, type - your fingers will thank you): sh ./BOINCxxx.sh That's: sh<space><dot><slash><BOINCxxx.sh> where "BOINCxxx.sh" should be the actual name of the .sh file you downloaded. Please do not attempt to use a GUI to do any of this. Don't footle about with "trash folders" or any other Windows-like metaphors with which you may think you're familiar. Linux is not Windows so almost everything you know about Windows is utterly useless here, and therefore it's also useless to attempt comparisons. This is a different operating system and there will be huge differences. Get the thing installed using standard documented techniques by the simplest method (and trust me, the shell prompt is the simplest in very many cases). Read the documentation about setting up seti/BOINC and connecting using the account connection information you have - and again, it's easier to do this from a shell prompt: you only type 20 or so characters - once - and that's it. Then once it's up & running and seen to be connected and working, only then play with the GUI. |

Unix/Linux :
failure to install BOINC
(消息 515255)
发表于：9 Feb 2007 作者： Bryn Post: I may have tried both methods. I am sorry to say that I am quite disappointed with the entire process of just installing Ubuntu, as it seems to require a very detailed level of knowledge that by definition, a newbie simply does not have. All this obscure command line stuff was a real pain. Perhaps I should start over. Do I delete the BOINC directory. but leave the BOINCxxxxx.sh file I downloaded, and use the Synaptic tool to re-install ? Not really that complex once you get used to things - it's just that this is a different operating system to what you're probably used to dealing with and so it requires different skills to use it. Once upon a time you didn't have a clue what to to with Windows (or Mac?) and had to learn that too. Assuming that you're at a console prompt logged on as yourself (meaning, not root) and the BOINCxxx.sh file is in your home directory, then just do: sh ./BOINCxxx.sh Obviosly not literally! - with the default 'bash' shell you should only need to type sh ./BO and then press the TAB key: the shell will auto-complete the filename for you provided there's only one file in the directory starting with "BO". If there's more than one then you'll hear a beep, so press TAB again to see the matching files. Now all you need to is type the next character required to identify the correct file and press TAB again to auto-complete the full filename. That should install BOINC in your home directory, in a directory called (surprise!) BOINC. If you want to make absolutely sure you're installing a fresh new version then before starting, carefully type: rm -Rf BOINC Again, this assumes you're not logged on as root and that the BOINC directory is in your home directory. |

发表于：9 Feb 2007 作者： Bryn Post: As for the processor chipset, whatever I have now (Celeron 500 I think) I will replace it with a Pentium motherboard I have sitting here, ready to go once I get the OS and SETI installed. That is, if I can get Unubntu to figure out I have a diskette drive. I am have seen the most bizarre behaviour imaginable trying to get files on/off a diskette under Ubuntu. I am not even sure I know HOW to tell what chipset I have, using Linux. If you mean what type of CPU you have, then from a console do: cat /proc/cpuinfo | less You should be able to scroll up & down the display using the cursor keys and when you're finished, press the 'Q' key to exit. If you mean the motherboard's chipset then that will take a bit more digging but it's not too bad. Honest! :) What problems are you having with the disk drive? (what's been tried so far & what happened etc.) AFAIK Ubuntu has no issues with floppy disk detection. |

Strange hard disk noise with seti/BOINC
(消息 512113)
发表于：2 Feb 2007 作者： Bryn Post:
It is just a horribly coincidental disk failure, believe me, and not BOINC misbehaving. There seems to be some evil law at work regarding machine failures - a month ago I needed to replace the battery in my server's UPS and since it's hot-swappable, I anticipated no service interruption problems. So I carefully extracted the old battery and replaced it with the new one, carefully slid the UPS back into place when suddenly, the server just powered off. It turned out that the machine's power supply decided to fail right then :( On another box I upgraded the Linux installation on the primary drive and within an hour, the secondary drive was no longer accessible. On investigation I found that it was kind-of being detected - but with a totally bogus cylinder count and manufacturer name. Moving it to another machine showed the same problem so it's definitely a drive fault. I knew the Linux install was fine because I'd updated another box months earlier with no problems whatever. (aside from the *very* unlilkely scenario that a Linux install would trash a secondary drive. I mean, we're not tallking Redmond here... ;) So, just because B happens after doing A, it doesn't necessarily follow that A caused B... |

发表于：19 Jan 2007 作者： Bryn Post:
Unnecessary, and not a good idea for two reasons: you'll end up installing it with root permissions which will cause problems later when you try to run it as a non-privileged user, and it's unwise to install BOINC as root from a security viewpoint. Assuming you're located in the same directory as the .sh file you downloaded in step 1 (ideally, your home directory) and sitting at a shell prompt, just do: sh ./boinc_5.4.11_i686-pc-linux-gnu.sh That'll default to installing it in ~/BOINC
Not required now.
On the Wiki page (IIRC) there are specific instructions for attaching to a project which can easily be done from the shell prompt. I don't use the GUI but I assume it's possible from there too. Also on the Wiki (er, I think - they've certainly been posted here too) are links to assorted automatic startup scripts.
Meh, it's just a question of a little light reading. ;) |

It certainly shouldn't, and it's sound practice to not run BOINC as root. I just run it as 'me' off my home directory - no problems. |

Unix/Linux :
Strange hard disk noise with seti/BOINC
(消息 487462)
发表于：22 Dec 2006 作者： Bryn Post: same problem, same noise each time I launch the boinc client. Sorry to restate earlier issues - but are you absolutely, positively certain the noise is directly from the hard disk? I ask, because on one of my Linux boxes and depending on what's being run I can make the PSU "sing" quietly to itself. It's a quiet but discernable rythmic burbling noise which stops when I run nothing as a user - or by running something else, I can change it to almost a "nee-nah" sound. Nothing noticeably different happens when I run the BOINC client and I assume the whole thing is just assorted inductors inside the PSU resonating according to different loading situations. Or, looking at it from another viewpoint - puzzling though it is (and really, it still needs an answer just because of that! :) I'm inclined to think that nothing "nasty" is happening because the drive will - and can only - respond to valid commands. It can only step at its maximum specified stepping rate and no faster, it can only drag data off as fast as is specified, it can't be made to seek cylinder (max specified + 1000) etc. and besides, if it was possible to even attempt exceeding any of these things then the quality of the OS or the application would be highly suspect! If it is indeed disk related and since the normal OS journal activity can be isolated, and as the other noise is clearly related to running the BOINC client - I suppose it's then a question of trying to discover exactly what disk access the BOINC client is making while crunching. A comprehensive peek could be obtained by using "strace" although the output would likely need much filtering to isolate the disk-specific activity, but at least any regular or rythmic activity which might correlate to the noises could be found relatively easily. Plainly there is something going on and I'm as puzzled as you are... I'm sure that with a little experimentation a reason will be found - heck, I'm almost wishing my system would make a BOINC noise now! :) |

Linux Boinc Image?
(消息 464169)
发表于：23 Nov 2006 作者： Bryn Post:
Well probably, but if your machine has the resources it's probably not worth the effort of trying to strip out stuff that BOINC doesn't strictly need. During the stripping out you also run the risk of breaking something too, unless you're very careful and are certain of what you're pulling out.
You could use one of the many CD-based linuxen I suppose - Knoppix, for example - which as downloaded just runs from the CD but can store aspects of its setup to the local hard disk - even if it has that other OS on it.
With the greatest respect - if you understood how it should work then you'd already know how to strip out the extra stuff. Why not just download something like SUSE: a very polished distribution, and you get the chance to not install certain bits during the (very easy) initial setup. Or, some folks seem to like Kbuntu/Ubuntu for their ease of setup. |

But, all my suspended uploads were successfully uploaded a few hours later. That yours didn't is the mysterious part... Maybe there's a clue in the reported "http error", which seems to me to be report of the status at the server, as opposed to your local BOINC discovering some problem with communication through http. The "Temporarily failed upload" comment also indicates to me that this is an expected, short-term duration failure. |
