    A small update to the cellular browsing

    ByEtzion 02/07/2008

    I have uploaded a replacement wvdial.conf for the cellular entry below. Notice that for Cellcom in Israel, you need an init string AT+CGDCONT=1,”IP”,”internetg” . which is embedded into the file. For other cellular providers, you might need a different string. For Cellcom users out there – this is the right init string. If you are on…

    A nice dial-up script

    ByEtzion 01/07/2008

    It’s either me, or NetworkManager sux. This is the most incomplete and incompetent piece of software I have ever seen. The only reason I actually use it is that there is no better alternative which does whatever NetworkManager manages, somehow, to do. My initial thought was to setup NetworkManager as the dial-up component. What should…

    Bluetooth Mouse on my Ubuntu Laptop – an easy feat

    ByEtzion 19/06/2008

    I was surprised at how easy it was. You need to do the following: 1. Find your mouse’s address using ‘hcitool scan‘ 2. Verify that you can pair the two devices using ‘sudo hidd –connect XX:XX:XX:XX:XX:XX‘ 3. Edit /etc/default/bluetooth, uncomment the additional line with the HIDD_OPTIONS and set it to be “–connect XX:XX:XX:XX:XX:XX –server” 4….

    Oracle ASM and EMC PowerPath

    ByEtzion 28/05/2008

    Setting up an Oracle ASM disks is rather simple, and the procedure can be easily obtained from here, for example. This is nice and pretty, and works well for most environments. EMC PowerPath creates meta devices which utilize the underlying paths, as mod_scsi sees them in Linux, without hiding them (unlike IBM’s RDAC, for example)….

    RHEL4 can see only 8 cores out of 16 cores server

    ByEtzion 21/05/2008

    I have encountered it on several cases. RedHat Linux ES, by default, uses smp kernel which is limited to eight cores, or two sockets. You find out that your multi-socket hardware, with its 16 (or more…) cores show you only the first eight, both by the simple method of running ‘top‘ and then pressing on…
