Router on a floppy disk

Solution:  freesco (free Cisco - I guess?)

Issue:  When I am working on some topology design and especially when using AD... I like to have my development area segmented from anything else that it may impact.  On my laptop I use DHCP on either em1 or wlan0 with your standard 192.x.x.x address.

To segment my development I use a "Host-Only" network, which has changed a bit with VMware Workstation 8 for Linux (not sure about the Windows version).  They now offer Host-Only and another option "LAN Segment".  I'm not sure what the limitation for these LAN Segments are.  But I currently have 3 configured.  I like this option as I believe it will be extremely useful testing cluster configs (for the LLT networks).

When I use freeSCO - I do the following:
download the freeSCO source and untar it (currently 0.4.3)
Create a virtual machine using "Other Linux 2.2.x Kernel" and 512 MB (proceed with defaults for the remainder)
remove the hard disk, USB, printer
make the "primary NIC" bridged (I imagine you could use NAT also)
add another NIC and assign it to a LAN segment (you will need to add a new segment)
# dd if=./freesco.043 of=/VirtualMachines/freeSCO-043/floppy.vfd
configure your VM to use the floppy.vfd as the floppy image

Boot and you should be on your way.  The remainder of the configuration tasks I will leave to the experts and their docs.  (I have little experience with freeSCO other than this extremely limited purpose - therefore, you should probably use their docs)

P2V using dd for KVM-QEMU guest

Preface: I have certainly not exhaustively tested this process.  I had a specific need and found a specific solution that worked. Situation:  I was issued a shiny new laptop running Red Hat Enterprise Linux 7 (with Corp VPN, certs, Authentication configuration, etc...)  The image was great, but I needed more flexibility on my bare metal.  So, my goal was to P2V the corporate image so I could just run it as a VM. * Remove corporate drive and install new SSD * install corp drive in external USB-3 case * Install RHEL 7 on new SSD * dd old drive to a disk-image file in a temp location which will be an image which is the same size as your actual drive (unless you have enough space in your destination to contain a temp and converted image) * convert the raw disk-image to a qcow file while pushing it to the final location - this step should reduce the disk size - however, I believe it will only reduce/collapse zero-byte blocks (not just free space - i.e. if you de...

Extending SNMP to run arbitrary shell script

Why are we here... This is not likely something I would have pursued under normal circumstances.  I happen to be working for a customer/client who is not afforded a lot of flexibility to accomplish their goals.  In this case, the rigor is justified.  They have to sometimes be fairly creative with how they solve problems. In this case they would like to utilize an existing snmp implementation to execute a command (or shell script) on a remote system.  They came to me with the idea of using Net-SNMP extend. https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/sect-System_Monitoring_Tools-Net-SNMP-Extending.html NOTE:  This is NOT a good implementation strategy in the "real world"  it will simply allow you to test the functionality.  There are a TON of security implications which would need to be taken in to consideration. Implementation Steps: [root@rh7tst01 ~]# yum -y install net-snmp net-snmp-utils ...

RHN Satellite Server (spacewalk) repomd.xml not found

"repomd.xml not found" If you add a channel, or if your RHN cache gets corrupted, and one of your guests complains that it cannot find repomd.xml for jb-ews-2-x86_64-server-5-rpm (for example) - you need to rebuild your repodata cache. Normally this is an automated job - which is exemplified by the fact that you have obviously built out your entire Satellite environment and never had to do any of the steps you are about to do. So - some prep work: Open 3 terminals to your Satellite Server and run: # Term 1 cd /var/cache/rhn watch "ls -l | wc -l" # Term 2 pwd cd /var/log/rhn tail -f rhn_taskomatic_daemon.log # Term 3 satellite-sync --channel=jb-ews-2-x86_64-server-5-rpm Once the satellite-sync has completed, you >should< see the count increment by one.  If you are unlucky (like me) you will not. You then need to login to the Satellite WebUI as the satellite admin user. Click on the Admin tab (at the top) Task Schedules (on the left) fin...
