wc (word count)
You can use the command wc to count how many words or lines are in a file and here are some examples: To count words using wc: wc -w filename At the shell prompt, type wc -w (for words) and the name of the file in which you want to count the words. To count lines with wc: wc -l filename Use wc -l followed by the filename to count the lines. This is useful for things like lists. To count files in a directory ls | wc -l Use ls with wc to count the regular files and directories or use ls -A | wc -l to count all files and directories (except for the . and .. directories) To count bytes of a specific file wc -c filename This shows how many bytes a specific file takes up. You could use wc with no flags at all to get the lines, words and bytes of a file.

du (disk usage)
A standard Unix program used to estimate file space usage—space used under a particular directory or files on a file system. As du reports allocation space and not absolute file space, the amount of space on a file system shown by du may vary from that shown by df if files have been deleted but their blocks not yet freed. Also the minfree setting that allocates datablocks for the filesystem and the super user processes creates a discrepancy between total blocks and the sum of used and available blocks. The minfree setting is usually set to about 5% of the total filesystem size.

Microsoft Lync logging / signing you out randomly
Have you had the issue where Microsoft Lync randomly logs you or signs you out and then struggles to log you back in. I believe this solution will fix the issue if you want to give it a shot If SCHANNEL is sending a truncated list of trusted root certificate authorities to the Lync phone edition client during the TLS/SSL handshake process, this can explain the symptoms. To check this look in your Lync FE servers system event log for the following warning: ---- EVENT ID: 36885 When asking for client authentication, this server sends a list of trusted certificate authorities to the client. The client uses this list to choose a client certificate that is trusted by the server. Currently, this server trusts so many certificate authorities that the list has grown too long. This list has thus been truncated. The administrator of this machine should review the certificate authorities trusted for client authentication and remove those that do not really need to be trusted. ---- The easiest way to fix this is to configure SCHANNEL on the Lync FE's not to send this list: Click Start, click Run, type regedit, and then click OK. Locate and then click the following registry subkey - HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSecurityProvidersSCHANNEL On the Edit menu, point to New, and then click DWORD Value. Type SendTrustedIssuerList, and then press ENTER to name the registry entry. Right-click SendTrustedIssuerList, and then click Modify. In the Value data box, type 0 if that value is not already displayed, and then click OK. Exit Registry Editor. You shouldn't need to reboot the server for this to take effect.

TCP Dump
Wireshark is my preferred method of capturing files but it does take more resources (CPU and Memory) then a command line based tool like tcpdump. It would be best to look at the manpage for all the options but I will give you the example below that I use on a regular basis which will continuously create 20Mb files and once 1000 files get created it will begin overwriting files. sudo tcpdump -i eth0 -nnvv -w /home/hosangit/captures/ustrocapture.log -W 1000 -C 20,000,000 Now that you have all these files here are a few tools you can use to analyze the data Wireshark tshark (tshark -i eth0 -b filesize:20000 -b files:1000 -n -t ad -w /home/hosangit/captures/filename.cap) tcpdstat ipsumdump Netdude I will include examples with each of these as I put them together with some screen shots.

In Search Of The Best Monitoring Tool
Request from user: You pretty much described Solarwinds Orion. You would have to purchase some add-ons they offer for all the functionality but I would say they can do about 90% of what you are looking for at a very low price and very little hardware (in comparison to the alternatives). Extensions you would have to add include : Netflow Traffic Analyzer This extension will add the ability to collect and analyze netflow traffic Application Performance Monitor This extension will help you monitor your application performance Network Configuration Management This extension integrates with Orion and helps keep an eye and archive your network configurations (like your configs on your network hardware) Orion itself lets you have unlimited custom fields for your nodes, when you search you can search on those custom fields or anywhere... its all in a sql database so its searchable. You can create a map but it doesn't (as far as I know) automatically add devices to the map based on the devices mailing address. Now that would be awesome!

Solarwinds
What a great network sanity tool that has proven itself time and time again. The price is less then the big names but I found after using it for several years side by side with some big names (Opsware, Netcool, eHealth) that Solarwinds is far more flexible, easier to use and the customization is fantastic. To demonstrate how easy it is to add a new device to be monitored, I'm going to show you below by using only the web interface. Before you get to far, be sure an Admin grants your ID the access to manage nodes STEP ONE.. enter the URL of the Solarwinds server and enter your login information. STEP TWO.. click on Manage Nodes (doesn't matter under what title (example Exchange Servers) because it brings you to the same place. STEP THREE.. Now you are presented with the Manage Nodes screen which should look like the below. Go ahead and click Add STEP FOUR.. Define the information about your Node (IP Address, SNMP string(s)) and click Next STEP FIVE.. If you have the SNMP string and it validated when you clicked next, pick the resources from the object you want to monitor (CPU, MEMORY, INTERFACE(S), HARD DRIVE, etc..) On a switch I like to monitor the interfaces/ports the WAN router(s) are plugged into, server(s) and any critical devices to include uplinks to other switches. I just don't monitor users or printers. STEP SIX.. Pick the poller(s) to use to monitor your device (you can have multiple pollers with Solarwinds to help reduce the load on the server. Some like to use a poller per region or business unit. Its not needed but nice to have multiple pollers.) STEP SEVEN.. Enter your custom property definitions. This is fully customizable from the server but you can add anything you want to track or group nodes together. So for example, switch location (city, state, country). This allows you to quickly find all the nodes in a city, state or country. I also use the custom fields for contact information so when a node goes down it sends a page with the address, contact1 info, contact2 info and some other useful information in the event I'm not near a computer to look it up. Some pre-planning if you are using Solarwinds to help you out in the future. 1.) When installing a switch, take the time and make sure the switchport descriptions are short and accurate. Come up with a naming standard that you could use Globally. Solarwinds will pull the switchport descriptions automatically and if you already did the work ahead of time you will save yourself a lot of time from adding alias's to the switchports later. 2.) Also when configuring the switch ensure you have SNMP Read-Only access as well as the Syslog Messages forwarded to your Solarwinds Server. This will make troubleshooting a site or hardware faster and easier. Also in the event of hardware failure, you'll have some final syslog messages from that device that could help identify what happened. 3.) Depending on the hardware, enable Netflow. This comes in handy when you are trying to find top talkers or bandwidth utilization on the WAN circuit. This requires a Solarwinds Add-on Module but is highly recommended and does provide some very useful information all in one place, your Solarwinds Network Monitoring Tool.

Add a Radius Client
Once you log onto the first Radius Server (you may have multiple and this change would need to be performed on each Radius Server) click on Start - All Programs - Administrative Tools - Internet Authentication Service Right click on RADIUS Clients and select New RADIUS Client as shown here Fill in a friendly name (alias) so you can tell what the device is when looking through a list. Also add the IP address of that device Finally, we are going to leave the Client-Vendor: as the default which is RADIUS Standard. Enter the Shared Secret (which should be the same on the device you added and here on the radius server) Click Finish and you are done adding a RADIUS Client to the RADIUS Server, now you need to make those changes on your RADIUS Client (whether its a wireless lan controller or a stand alone access point)

Wireless Access Setup like the Hotels
I pay for internet for my building but not a big fan of users not in the building using my purchased internet. Everytime I travel and stay in a hotel or am at the airport, I have am presented a login the minute I launch my browser. What a great solution, I would like to implement the same thing in my building. So what do you need to keep this inexpensive as much as possible... Ubuntu Server or Desktop (these instructions were tested using Server version 8.04). A x86 machine with two network cards (this could be an old laptop, desktop, whatever). Defining some stuff: 192.168.2.0/24 is the private network that everyone will get an IP address from which means 192.168.2.1 to .254 are valid IP addresses with a subnet mask of 255.255.255.0 (probably a bit too much information but I'm sharing it anyhow). The ubuntu server will be supplying the IP addresses (acting as the DHCP server) so if you access point is currently doing that task... turn off the feature of being the DHCP server. 10.0.1.0/24 is the internal network that is hot to the internet. So your desktop will have two network interface cards (NICs) and we will label them as such: eth0 = This will be the internet hot address (most of the time this is setup to receive an IP address from your Internet provider or possbily another Linksys Router that is connected to the internet. eth1 = Private network (this will not be assigned an IP address and will be the interface that will be handing out IP addresses to clients that wish to access the internet) Note: This solution does not work well under VMWare Server or Workstation. I spent many hours trying to get this to work under VMWare and never had success and the first time I tried this on a dedicated old piece of doo doo, it worked fine. Let's begin the installation... 1st download the .iso from Ubuntu and burn that to a CD and go ahead and follow the prompts to install (when tasksel launches asking you to install option components, you can go ahead and select LAMP and SSH Server)... you'll need these. Now the rest of the instructions for ChillispotHotspot can be found here
