Vmware command line update

I needed to update ESXi to get the latest drivers on my UCS C220-M3.  This article and this download seemed to do the trick for me.  The UCS ISO came directly from VMware.  I had to log in, but didn’t look like it validated a license to do the download since it was just an update not the install ISO.

Upgrade to Lightweight AP to Autonomous

Several times while trying up upgrade an AP that wasn’t connected to a controller I got hit with it rebooting partway through the upgrade.  I stumbled across this in the support forums

ap#debug capwap client no-reload

 

(this hidden command prevents the AP from reloading when it can’t join a controller)

I tried it and worked perfectly on a 2702, posting it here mostly as a reminder for myself.

CCNP TSHOOT 642-832 Book

I finished my CCNP about 2 weeks ago, however I didn’t read the TSHOOT book by Kevin Wallace before doing so.  Before diving into my CCIE studies I figured I should read this book.  Now that I’m done I’m really glad I did.  I think it very concisely covered all of the topics, and while I think its certainly possible to pass the TSHOOT test without reading this book, I think its well worth the time.  I can see myself referring back to this book many times as I go through the CCIE materials.

Bash Script to identify new IP’s on network

Yesterday I was trying to add a camera to my home network.  I knew that I’d previously configured it with a static IP but I had no idea what it was.  In the past I would just do a ping scan with nmap and look for the device.  But now I have over 30 hosts on my network and scrolling through that list is a pain.  I threw together this ultra basic script because this type of thing is happening more and more.  It doesn’t get much simpler than this, but it worked perfectly for me.

#!/bin/bash
echo “What network do you want to scan (/24 only)”
read network
echo “Creating baseline, please wait”
nmap -oG – -sP $network/24 >> baseline.nmap
echo “Baseline created, please plug in the new device and hit enter when it should have booted”
read
echo “Scanning for new devices”
nmap -oG – -sP $network/24 >> new.nmap
echo “New scan complete”
diff baseline.nmap new.nmap
rm baseline.nmap new.nmap

 

I’m sure there are better ways to do this, but this took 5 minutes and did the trick.  Maybe next time I use it I’ll make it a touch fancier

Upgrading to Cisco Wireless AP’s from a residential AP

The Problem:

I live in a 2 story house with a basement.  My office is in the basement as well as the cable modem and wireless router.  I’ve been using a netgear residential access point for awhile now.  It does a decent job, basement and 1st floor have good coverage, but streaming video to the 2nd floor is problematic and there is zero signal on the front porch.

The Solution:

Cisco 3602 Access Points (Datasheet).  I’ve got 2 of these I can use. One in the basement pointing up, and one in the attic pointing down should give me pretty decent coverage.  I have the AC modules for them as well, however I’m going to leave them off for right now as I don’t have any clients that can make use of them.  These APs support the Cisco Clean Air feature.  I have high hopes for this feature, walking around my house running Netspot on my laptop I pickup 42 different networks.
