Large load average when running dd to a CF card
by Srdjan Todorovic 19 Jan '10

19 Jan '10

Hi all, Any ideas why I get large average loads (8.82, 4.20, 1.80) when running dd that copies 2GB of data to a compact disk flash card using a USB disk reader in Fiesty (or whatever it is called)? If I kill dd, the load drops to more sane levels. It just hit 9.9 :( Thanks, Srdjan

preventing shutdown with remote working going on
by Peter Alcibiades 18 Jan '10

18 Jan '10

How do you stop users from shutting down the system if there are other people connected, but allow them to shut it down if there are not? Here's the background, I have machines A and B in different locations. Machine A is sometimes going to be used by just anyone, on account X, and sometimes by the main secretary on account Y. Sometimes, to allow the others to work on Machine A, the secretary will decamp to another room, and continue to work on account Y on machine A, but will be phyically located at machine B. Now it occurs to one, life being what it is, that from time to time some other user sitting at machine A, not used to the concept of multiple logins, will just try and turn off the machine while the secretary is working and logged in on it on the different account. How do I stop this? Hopefully by sending a message to the effect, you cannnot shut down this machine because there are other people connected? On the other hand, I don't want to stop all user shutdowns, because often there is not going to be any remote connection. I'm proposing to just use XDCMP by the way, for the remote working, since we are behind a firewall router. This is safe enough in that case, isn't it? Peter

Re: [ALUG] How to diagnose heavy system load at power up?

Give bootchart a go (usually available in your distro as a standard package). http://www.bootchart.org/ You should get a nice picture of where all your CPU and memory is going at startup.

To: main(a)lists.alug.org.uk Message-ID: <20100115165744.GB4223@chris> Content-Type: text/plain; charset=us-ascii I recently noticed that if I log in to my xfce GUI straight after powering up my computer it takes an inordinately long time. Like it takes four or five minutes from when I enter my name and password to when the desktop appears completely. After suspecting that there was something awry with my X startup (such that it was doing something odd the first time it was run) I realised that it was simply that the system was very heavily loaded by something during/after boot. Watching the load average during the X startup it went over 8 whereas if I login to X after the system has been running for some hours the load average reaches the giddy heights of 0.14. With a load average of 8 things almost grind to a halt, some processes retry starting (I get more than one xfdesktop for example) and update-notifier times out trying to access repositories which it has no problems at all with if I log in later. Another symptom is that some nfs mounts haven't completed before the terminal windows appear on the desktop so when I run mutt (mail program) which uses one of the NFS mounts it fails to see its mail directories. That's seriously wierd. I've tried to analyse what's going on by running top (and 'w' and ps) in a console window while the system starts up but I really can't see anything obvious that's hogging any resource. One noticeable thing apart from the load average being so high is that my 8Gb of memory gets eaten up too, but there seem to be no particular processes using either lots of CPU or lots of memory. Can anyone suggest further ways of trying to diagnose this? -- Chris Green

Problem with anacron and cron *never* running jobs
by Chris G 15 Jan '10

15 Jan '10

I have a backup job that (should) be run daily. There is a script called 'backup' that is in /etc/cron.daily. If the computer is shutdown regularly then anacron does its job and runs backup a few minutes after the computer is powered up again. If, on the other hand, the computer is on all the time then cron runs the job at 07:30. However, and this is the problem, if the computer is Suspend[ed] and isn't running at 07:30 then the jobs in /etc/cron.daily never get run. Is there any way around this? -- Chris Green

Another Lunx vs Win issue!
by Ted.Harding＠manchester.ac.uk 14 Jan '10

14 Jan '10

Greetings Folks! A friend recently sent me the following URL: http://www.oddcast.com/home/demos/tts/tts_example.php?sitepal What *should* happen (and happens when I open it in Win IE) is that the main box (with the panel of boxes below it) should show a face (female in the first instance) which is animated (e.g. if you move the mouse-pointer over that window the eyes will follow it); and, when you enter some text in the "Enter Text:" box then click "Say It", the mouth-parts move and you will hear that text spoken. (The other boxes below the main window let you choose the regional accent and speaker, etc.). However, on my Debian Linux (Etch or Lenny) with Firefox there is no face in the window, and when I click on "Say It" all I get is a pop-up which says "It is not ready yet". Does any of you succeed in getting this to work as described in Linux? If not, I wonder why not. I wo9nder whether I have sufficient resources of Java or PHP installed, but not having hit such a problem before I'm not sure whdether that is a good direction to be hunting in. Any comments or advice welcome! With thanks, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)manchester.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 13-Jan-10 Time: 20:27:40 ------------------------------ XFMail ------------------------------

According to 'man dbus-launch' this doesn't connect said program to the dbus session bus on your desktop, but starts a fresh session bus on the remote machine - thus your application config (in the case of Yelp) and other dbus connected services are stored on the remote machine. Said man page also indicates that a dbus session should be started automatically by the libdbus client if there isn't one running however this seems to fail in your case. P
