Sign in to Cisco, follow the instruction and download the file. You will get a zip file with two PDF files

One of these two (eDelivery_xxxx.zip) will give you the Product Activation Key.

Follow the instructions again and go to http://www.cisco.com/go/license, fill in the forms to register the switch.

Use the following command on the switch to retrieve PID and SN

Switch#show license udi

This week I decided to see what’s new. I don’t quite remember what the website was then, but it is now also available in version 4.72 at www.logmett.com with a set of new tools and sample codes. I haven’t tried logmett but did try the TTLEditor which is also nice. In the sample file the ssh2login.ttl (auto login with SSH2 protocol) gave me the starting point I needed to work on scripting multiple devices. A couple of hours later, I have a script that will:

• Read a file for remote ip address to connect to
• Connect to host
• execute command
• Log session in another external file

I’m not a programmer and the commands scared me quite a bit. Yet I was surprised to see how fast I start seeing result. Some commands seems to be duplicates, some just seem not to work. The “wait” command is the one that doesn’t work, yet, that is the one you expect to be using the most often to synchronize the command execution and the response from an inattended session. The work around was to put “pause” hoping the time allocated is enough for the response of the remote device. The programming level is quite old using “goto” rather than using functions. It can get quite confusing specially when reading other people’s program. Anyways, enough of ranting and more of coding..

Looking for a machine  strong enough to create A virtual environment consisting of a domain controller (WIN2008R2) with Exchange 2007 and Lync 2010 (to simulate our actual infrastructure) and 2 Windows7 clients. Preferably something I can access from home as well as from work.. (At work I don’t have the time to test and learn new stuff, home not really where I should be doing it either but that’s the way it is..) I tried my home server with Proxmox, but I quickly ran out of memory (damn Windows server!!). Eventually, installed it on my laptop (with 8Mbps of RAM and more that enough CPU).. on my Ubuntu partition (optimize the RAM) and Virtual Box. Eventually, I managed to get everything installed and did most of the documentation and configuration at work. It took a few tries but I got it going all in Virtual. It was long and tedious but very cool results. I eventually install it at work in less time it took me to install the three servers in Virtual box.

Oh yea, nearly forgot about DD-WRT. I needed to have a layer 3 separation between my test environment and the Internal/home or enterprise network going to the Internet. The reason is I didn’t want to broadcast the Netbios and Domain Controller information from the test environment to the local one. So after trying a couple, I simply used an image of DD-WRT in Virtual Box. Unfortunately, it doesn’t save the configs but that wasn’t a big deal, it’s set up and most important, it doesn’t take much mem..

For Microsoft users, get the Lync Client, Lync Attendee or just use the web apps..

For linux users, install the sipe plugin for Pidgin, chat functions work well..

To my surprise though, natty came with isc-dhcp-server. It took me a little while to figure out that to enable it, I only needed to copy and correct the subnet option int

/etc/dhcp/dhcpd.conf

subnet 192.168.1.0 netmask 255.255.255 {
range 192.168.1.0 192.168.1.100;
}

and set the interface on which I wanted to have DHCP to an ip address in that range, e.g.

$ ifconfig eth0 192.168.1.1

and start the service..

$ sudo /etc/init.d/isc-dhcp-sever start

et voilà..

Check the DHCP Request and distribution by

$ tail -f /var/log/syslog

Done..

But very often these forms are encrypted to avoid modification or what not, but than means you have to print it right away, so you have to fill it up one shot, not coming back and finish it later. If you don’t have a printer handy r you actually need to email the form (no signature required) you can always print it back in PDF. But if don’t always have the time to fill it completely and need to come back later to make modification, then you’d be happy to know that the encryption on these files are not that strong and you can take it out quite easily.

$ sudo apt-get install qpdf
$ qpdf –decrypt –password=mypassword input.pdf output.pdf
