About
I have been a UNIX and Linux system administrator for almost ten years now, and used Linux and UNIX for many years prior to that. I even ran all the UNIX utilities I could in my MSDOS environment, including awk, Perl, and especially vi. I began with Eunice (on a VAX) and later became familiar with Microport System V.
I am also certified as a Red Hat Certified Engineer (RHCE) and as a Sun Certified Solaris Administrator (SCSA), as well as LPIC-1 certified and Linux+ certified.
I’m currently employed by a major healthcare software producer.
When I’m not programming, I might be writing, shooting pictures, organizing, or learning something new.

The E500 will boot from CDROM. If you plan to run from CDROM, better beef up the memory.
It’s too bad the disk controller is bad - that cuts down a lot.

Hi DAvid,
Non technical question here - I’ve been a Linux \Solaris Admin for 3 years now
I just read you’re Tech Target article where you suggest that we should learn to write our own Linux Modules
Can you be more specific - I love debugging using Strace & Truss & would like to learn more in depth
Can you suggest on what I should learn to write my own modules & improve my debugging skills

There are several books on kernels and system internals - I’ve seen some on Solaris Internals, MacOS X Internals, Linux Kernel, and UNIX System V.
For drivers specifically, I’d recommend Linux Drivers from O’Reilly Press.

Hi David,
As sys admins we’re always dealing with Vendor Proprietary Software on our Servers. If you’re dealing with performance issues on the server - I’m sure you may have faced similar issues
What methodology to you generally adopt for dealing with this besides doing the obvious like running IOSTAT, VMSTAT,MPSTAT,TOP..etc
Do you debug system level calls to see if there are issues? - I’m sorry oif my question sounds amaterish. I’m new at this and trying to learn
