I first made the Download Section for members only, just cause I wanted an idea on who is downloading the software I have written. Now, I no longer care who downloads it, as long as it helps out the people who did download it. That is all that matters. Though the forums section, does require you to be a member. I also recognize, most people are members of enough websites, that becoming a member of another one, can be over bearing.
For those of you who visit linuxdynasty everyday, you might have notice some subtle changes in the authorization aspect fo the site. I had to enable captch images in the login, and posting parts of the site. Since for the past few weeks, spammers have been hitting the comments and forums section. I’m hoping this does not annoy everyone, but the spamming is starting to really annoy me.
It is official, I have begun development on the Web Server and Database for the Port Report Project and the Network Device Manager Project. I will be combining both scripts into a True Network Device Manager. My goal is to create an Open Source Network Device Manager that will give Admins and Engineers complete Insight/Access to their network. It does not matter if you want to know which switch your ESX host is directly connected to or if you want to manage all your Switches/Linux Hosts with this product. We have a few more ideas on what we want to do, but they are just ideas and I will not post them yet.
I will be using Python, Pexpect, PySnmp, SQLAlchemy, and Django for this project. I’m hoping to have an Alpha for users to test by late November or early December. If you are interested in this project, please give me ideas on what you would like to see in this Project. Currently we do not have an official name for the project. If you have one, let me know as well. All ideas are welcome, as we are trying to make a complete enterprise product out of this project.
Today I was given a task to have my manager emailed once a day. If any of our Data Stores in ESX 3.5 are over 80% utilized. So I said to my self. What would be the easiest way to do this???? Well I’ve written two scripts in the past, that could help me accomplish that. The first script VMstoragePool.py will list all of the Data Stores in Vmware and its utilization. The 2nd script is check_datastore.py, and this script will return OK, WARNING, or CRITICAL, depending on the thresholds you set. So by effectively combining the 2 scripts I was able to get what I want. Example below…
python VMstoragePool.py -u "https://esxhostA" -a "login passwd" |grep "DataStore Name" |awk {'print $3'} |for line in `xargs`;do python check_datastore.py -u "https://esxhostA" -a "login passwd" -d $line -w 80 -c 90 -m "GB"|grep -P "WARNING|CRITICAL";done|mail user@domain.com
CRITICAL XythosVol2 57GB Avail 94% used |avail=57
WARNING XythosVol1 62GB Avail 87% used |avail=62
WARNING LinuxVol1 57GB Avail 88% used |avail=57
WARNING WinVol1 75GB Avail 84% used |avail=75
WARNING BBSCVOL1 122GB Avail 88% used |avail=122
CRITICAL NSSharedVOL1 46GB Avail 95% used |avail=46
So I can run this script in cron once a day and pipe the output to email him directly. Simple yet effective! On a side note, I fixed both chec_datastore.py and VMstoragePool.py to effectivly parse passwd’s that used characters like !@#$%^.
Both scripts can be downlaoded here..

The current issue is that we have over 400 Cisco Network devices, and they are not all in the Cisco LMS ( Lan Management Solution ). We also have Solarwind, but we do not have all of our Networking devices in there either. There is only one way I know of doing that with out using multiple tools like Cisco LMS or Func. So I figured, I should go ahead and write a Python tool that can update all of our devices ( Cisco, Nortel, Foundry, Linux, BSD, you get the idea.. ).
I wrote a Python tool that utilizes pexpect. The tools is almost complete to release on my site, but I still need to add more functionality. Currently, you can pass a device list and a command list to the script. You can also tell the tool to be verbose and print the output. Also you can tell it to use ssh or telnet or both. The tool is smart enogh to use ssh keys or log into a device you never have logged into before, by accepting the key for you.
I’m currently modifying it so that you can just pass one device and not just a list of devices. Also working on a password changer function. I’ve tested my tool on Linux Servers as well as Cisco devices and so far it works like a charm. I’m thinking about adding threading, but I have not yet decided to do so..
The Port Report Project is essentially a Switch Port Mapper Tool or a Switch Port Mapping Tool like a few other commercial products out there, except The Port Report Project is free. Right now there is no GUI or WEB interface for the project but it is in the works.
Here is a quick update….. I just add dns reverse lookups to the output of this script.. So if you have Pointer Records set on a good part of your infrastructure, you will get the host name to those MAC Addresses that have the IP addresses in the ARP table.

Example below…
Here is an example from running port_report.py with the –report option..

This is a big update for Port Report…. In this revision the following brands and devices are supported
The Script has been tested with the above devices… If you have run this script against other devices, please let us know. Also the speed in the report function has drastically increased. I ran this script against a 6509 with 800+ devices connected to it in just over 2 minutes.
The main article for this script is located here http://www.linuxdynasty.org/howto-find-the-port-on-a-switch-that-a-host-belongs-to-the-easy-way-part-1.html
You can download the script here http://www.linuxdynasty.org/View-details/Python-Scripts/39-port_report.py.html

I have not yet finished my testing with Nortel and Foundry. Once that is complete, then I will post 1.7 revision. Though in the mean while I was able to enhance the –report option of the port_report.py script.
It use to take me about 13 minutes to scan our 6509 Core Switch and I was just able to do it under 4 minutes. So when I do post the update, not only will you get 2 more brands supported you will also get speed improvements as well.
As of right now I am very close on getting Nortel to work. I have been testing with Kshort and I’m hoping to have the Nortel part of this script done by tomorrow night. Once Nortel is done, then I will start working on getting Foundry Switches supported. Then I’ll release revision 1.7. If any members have run this script on Dell switches, please let me know if it worked or if if did not work. If it did not work, please contact me directly and I will try to get it supported as well.
Let me make this one thing clear about port_report.py and one limitation it has when searching for IP Addresses on a switch ( not really a limitation of the script ). When searching by IP address, the IP Address has to be in the ARP table, if the IP is not in the ARP table then the script will report that the IP Address is not in the ARP table. I know I sound redundant but I have been asked this question alot. The better thing to do is to search by MAC Address as this is more then likely to be on the switch. That is all depending on how often the table gets clean.
Currently, the newest revision, is revision 1.6.
