5/02/2010 15:05 - Just reading some Cisco stuff and came across some commands I wish to preserve:
show platform hardware capacity - To check into Switch Fabric utilization
show interfaces capabilities - particularly the field Ports on ASIC: due to this email thread. Also just started hearing about TRILL, not sure about that yet.
1/29/2009 10:06 - A month or so ago I decided to give Linux on the Desktop a real try. Many years ago
I tried it for maybe a day or so, and wasnt ready to commit. After a hard drive failure I decided to
go Ubuntu over Windows XP. Thus far it has been met with mixed results. I love having the UNIX commands
so readily available, but stability has been an issue (I think it is an XWindows - ATI driver issue).
Anyhow, last night I let Ubuntu do some updates and this morning VMWare was broken. The client would start
launching but after 10 seconds would go away. I hit the console and saw that some vmware services were
running, but not everything. I tried sudo service vmware start and recieved a message about this
vmware not being customized for my kernel, or something like that.
Later today I remembered that I had to apply a patch to get it to install and work in the first place, so
thats what I am documenting here. installs/vmware/vmware-update-2.6.27-5.5.7-2$ sudo ./runme.pl
1/15/2008 6:43 - Forgot to mention that my manager, Michael and I completed the ISC SANS packet

according to telcodata)
I opened the txt file and it appears to be the same text as above
12/12/2007 11:04 - I had to troubleshoot a blasted Cisco Catalyst Express 500 Switch today and
we have figured out the problem, but I wanted to share a very useful bit of info.
You can get more control of the switch by using a backdoor (so to say). If your switch
is accessible via http://10.0.10.9/ then you can access this by using http://10.0.10.9/exec/ .
You can then click the "Exec" link and you receive a text box and a button that allows you to
issue CLI commands such as "show mac-address".
11/22/2007 9:49 - I made this little script to make ISOs from the Suse Installation media
#!/bin/sh
echo ""
echo "dumptoISO.sh - Interactively prompts user to insert SuSE CDs and dumps them to ISOs"
echo "Please enter the total number of CDs you will be dumping: "
echo ""
read num
num=$[$num + 1]
counter="1"
while [ $counter -lt $num ]
do
done
echo "Your ISOs are now dumped in /usr/local/src/SuSE-CDS/"
11/22/2007 9:45 - SSIDs on Windows Zero Configuration Wireless utility seem to be stored in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WZCSVC\Parameters\Interfaces\{INTERFACE_CODE}
Each SSID has its own "REG_BINARY" entry, for example "Static#0000".
11/22/2007 9:32 - This bit of info is from the earlier half of this year, but I need
somewhere to record it, so here it is.
I was trying to install Slackware 11 on a Dell PowerEdge 840. I would boot using huge26.s
and it would install. I then rebooted and LILO was unable to load the linux boot section
"EBDA is big; kernel setup stack overlaps LILO second stage"
To fix it, I rebooted using Disk 1 of the Slack installation CDs, used huge26.s. I logged
in as root then mounted the / partition, "mount /dev/sda1 /mnt" then changed it to be root,
"chroot /mnt". I then ran liloconfig and setup LILO to use the MBR. This worked.
10/12/2007 17:58 - Yesterday we needed to do a "policy NAT" where one particular
client (based on Source IP) would be directed to a different real server than the
the rest of the clients (the rest of the Internet). I looked at doing this on the ASA
but using statics with Access-lists still complained about overlapping publics.
My coworker suggested using the F5 BigIP LTM. We looked into it and discovered that
this could be done using an iRule. After some research and trial-and-error
this is what we came up with. It works just fine.
when CLIENT_ACCEPTED {
if { [IP::addr [IP::client_addr] equals 10.45.250.2] }
{
pool Testweb
}
else
{
pool WebServers
}
}
I applied the iRule to the Virtual Server that is for port 80 only. Based on the source IP address they will be redirected to one of two different pools.
10/11/2007 19:38 - For right now this is going to be my tech "blog". I received a VMware VM from class and copied it over to my VMware server and could not get it to start. When I start the VM in windows it would start, the difference is that my server is linux. I would remote VMware into the linux server and use the GUI app to start it, and the screen would just be blank. So I decided to try from the CLI:
./vmware-cmd blah.vmx start
and boom. The console reported that I could not start the VM because the file permissions were Read-Only. I used chmod and fixed the permissions and then my VM was up and running.
07/07/2007 16:16 - I have composed a few Network Engineering related Search Plugins that I have begun to use. They are posted here.
