  • Unix Tip: Terminating unattended processes

    Posted March 26, 2008 - 3:59 pm

    A reader recently asked how he could most easily terminate processes that were left running after his users had logged off a system. The processes in question were apparently consuming resources needed by other services and were not contributing to any particular project. What he was looking for, however, was a solution that would not require him to detect the processes and manually terminate them, even if commands such as "pkill -u username" might simplify the job.

  • Windows tip: Sizing your event logs

    Posted March 17, 2008 - 1:10 pm

    The Windows Event Logs are a good thing -- they're a primary source you can mine when troubleshooting server problems or monitoring server security. Because of this, it's a good idea to collect as much information as possible in these logs in order to provide you with a historical baseline of your server's operations to help you troubleshoot difficult issues, and also to create an audit trail for security purposes. The trouble is, can you have too much of a good thing?

  • Unix Tip: Burning bootable DVDs

    Posted March 5, 2008 - 9:43 pm

    One of the messages that you don't want to see when getting ready to upgrade a system to Solaris 10 is "can't open boot device". The problems this kind of error suggests, such as bad CD/DVD reader or improper device alias, can be troublesome. So, when I ran into this problem on a Friday afternoon, I was not amused. I had tried various boot commands, but got the same basic response each time...
  • Windows Tip: Getting RunAs back in Vista

    Posted February 29, 2008 - 4:16 pm

    For the last while I've been on the Service Pack 1 beta for Windows Vista and in my opinion SP1 has fixed most of the issues the original RTM release had, especially performance issues.

    Posted February 26, 2008 - 1:23 pm

    To understand how this works, think back to how the shell processes what it sees on the command line.
