Can anyone throw some lights on
whether it would be OK to test the performance of USB interface by iozone utility???
Or there are any other better options available???
I have a couple of large-format printers (Epson R2400, HP 9650) which I only use infrequently. If they are not used very often, they dry out, the print heads get packed up, it's an expensive mess to deal with when times comes to run off some prints. The printers are physically connected to a Windows machine to which my Ubuntu computer is networked.It would be helpful if there was a utility that could initiate a test page print job on the machines, which could be scheduled to run once a week or so. I've had no luck finding such a thing for Windows

I'm interested in testing the difference between using the proprietary ATI driver and the open source driver and also the performance under various distributions.
What's the best software to benchmark graphics cards?
I am in the process of running a set of performance tests for the latest Sun JVM 1.6.0_20. I am using for that the dacapo test suite: [URL]
I ran the test suite very often with all sorts of settings, but recently it happened once that my Ubuntu system froze. I could still ping the machine, but nothing else was responding any more, no screen output, no ssh login, not possible to switch consoles. After rebooting the system the system logs were quiet. No single trace of any problem.
I am using a custom compiled kernel 2.6.34: Linux i7 2.6.34-custom-201005231602 #1 SMP PREEMPT Sun May 23 16:06:01 CEST 2010 x86_64 GNU/Linux and I am experimenting around with the -XX:+UseLargePages JVM switch the requires to set-up the hugetlbfs on the Linux system: [URL]
A similar issue happened in March 2010 on one of our CentOS 5.4 systems where we run a heavy load Java application on, where we had to hard power off the machine and after the reboot there was no trace of the problem in the logs. On that server we used JDK 1.6.0_17 and did not use hugetlbfs.
My first question would be what to do so that next time something like that happens I have more information available after the incident to debug and analyse the problem?
I'm looking for a Linux program that will do some simple network performance/stress testing.

I just wanted to know if having my laptop set to ondemand, will this affect performance in any way? I realize it increases the clock speed to performance when the CPU is under load, but does the time it take to go from ondemand to performance affect speed? Will there be any noticeable difference between the two setups? I have a dual core intel at 2.2GHz when in performance. When ondemand is set with no load it downclocks to 800Mhz.

You can try to start the mysqld daemon with:

and use the command line tool /home/mosty/mysql/bin/mysql to connect to the mysql database and look at the grant tables:

i am using windows 7 in my laptop and linux is installed on virtualBox but my problem is the screen is showing small in virtualbox is there any way to enalarge the screen to show like windows screen? i did before by using VGA setting but it made problem me i was not able to use GUI interface i meant graphics interface
it was just showing me Command Prompt.
When I do...# iptables -L...I see rules in my INPUT and OUTPUT chains that look scary:ACCEPT all -- anywhere anywhere...but these rules only apply to the loopback interface. I tested it and the server cannot be reached on open ports from the outside world. How can I make iptables show the interfaces that the rules apply to?Otherwise, every time I do iptables -L it will scare the crap out of me.

Acoording to this manual:[URL]there are two installation methods:* Burned: boot from a LiveCD and then use the 'Install to USB' utility.(NOTE: Which LiveCD in particular ... and is it going to install a Debian distro ?

View 2 Replies View RelatedIn recent versions of Ubuntu, it is possible to click on the top right corner to choose to shut, down, log out, etc as opposed to having buttons that need to be clicked on followed by other buttons. Ubuntu's current utility works by clicking on the top right corner which shows a list without opening a new mini-window or anything allowing me to select however it is that I want to change the state of my computer if it wasn't obvious as to what I am referring to.

I'm on xubuntu.
Under unix/linux, there is this extremely useful program screen: it's for bash, text-only, and I can detach a session, log out (the session is still running though), log in later (even from a different computer) and resume the session exactly as I left it. My question is, is there an equivalent to screen for X? So what I want to do is: work remotely with ssh -X in an X-session on a remote linux machine, log out, then later log in from a different computer again with ssh -X and then re-attach the X-session; practically resuming work from the moment when I logged out before. Is this possible?
