About Dramsey

Email: MailTo(dramsey AT fedoraproject DOT org)

Located on the far right of this picture (in the pink shirt,) I am a Fedora 9, 10, 11, and 12 user currently experiencing the x86 version. I am trying to integrate useful system administration ideas for my Fedora systems.

I am very interested in large memory model programs and multi-core computer systems. I enjoy using virtual machines (VMs) in order to develop a formidable system solution. Through the use of VMs, I am able to try out a variety of software solutions on a VM prior to installation of the software on my production system.

I have taken RH033VT, RH131VT, RH253VT, and RH301VT coursework, in order to further establish my Red Hat educational foundation. My next training class will be the "Red Hat Enterprise Linux Update Course" - RHUP305

Virtual Machine Information

Virtual Machine Information

Each VM has 3072 MB of RAM as well as two CPU cores allocated for execution and evaluation purposes within an established baseline VM system.
My latest Fedora 12 (Constantine) kernel is 2.6.31.9-174.fc12.i686.PAE. I am very interested in progress in GRUB Ext4 support, NFSv4Default and NetworkManager System Connections
Good to see how the iBus Intelligent Input Bus "input framework method system" and Ext4 file system "checksum feature for the journal" have developed.
When I have the VMs running with 1536 MB of RAM, I am able to enjoy using VMs for executing my Fedora 9, 10, 11, and 12 systems. With the effective use of VMs, I am able to concurrently run 9 VMs on my workstation. There are three pictures at the bottom of this page:

Current running systems

Current running systems

Version	My current running kernels	Status	Memory	Swap space
Fedora 12 (Constantine) Alpha, Beta, and RC three systems running with VMware	2.6.31.9-174.fc12.i686.PAE		3.0 GB	4.0 GB
Fedora 13 (Goddard) one system running with VMware	2.6.32.2-18.fc13.i686.PAE		3.0 GB	4.0 GB

Software which I like to have running on my systems:

aide
dsniff
hdparm
iotop
logwatch
nmap
ntop (considering)
tripwire
wireshark
xosview

Some system information

Food for thought

This is a tip
My current workstation has eight (8) x86_64 computing cores and 16 GB of RAM as well as two 500 GB harddisks (SATA Seagate 7200.12.) The Seagate 7200.12, 500 GB harddisk is only "one" platter and is very quiet as well as very low power consumption and fast for my use. I am considering a plan on doing an upgrade to the Seagate 7200.12, 1 TB harddisk next calendar year.

Another tip
Google's IPV6 web site - http://ipv6google.com/ try it.

This is important
A finding on my behalf regarding concurrent guest operating systems is to keep the ntp time clock in sync between the variety of guest VMs.

This is something else important
Fedora 12 Alpha with 3072MB of RAM. After that amount of 3 Gigabytes (GB) RAM, the 32-bit kernel is abending. Also, the "Swap" space is defined about 4 GB.

This is a note
The Fedora 11 and Fedora 12 Alpha version's "Swap" space are defined about 3 GB, versus the Fedora 9 and 10 versions' "Swap" space are defined about 2 GB when all versions were provided 1.5 GB of RAM.

This is an additional note
At this time, I am not really very impressed with the dracut product. The dracut execution time was about 15-25 minutes to update my kernels dependent on the virtual machine being used. As of September 22nd, 2009, I have used dracut about 40+ times. Maybe when the F12 Beta and/or F12 Final Release are made, dracut will be better. Update, with F12 Beta and RCs, the dracut execution time is now about 2-3 minutes.

This is a warning
A little FYI on updating to the 2.6.31-2.fc12.i686 and 2.6.31-2.fc12.i686.PAE kernels, a separate rpm install was needed of the bindutils-2.19.51.0.14-31.fc12.i686.rpm package from the original install media's iso, in order to address the bindutils dependency prior to updating to the 2.6.31-2.fc12.i686 and 2.6.31-2.fc12.i686.PAE kernels.

This is a caution
Currently, the Virtual PC 6.0.156.0 and the F12 Alpha iso are having some serious problems with getting X to work. Therefore, my /etc/inittab file on those test subsystems is set to run at runlevel 3 instead of 5.
