Setting up Web Proxy Autodiscovery Protocol (WPAD) using DNS
In order to use the DNS only method to setup Web Proxy Autodiscovery Protocol (WPAD) you need to check on the following
- To use WPAD using DNS method a DNS entry is needed for a host named WPAD. This name should be resolvable from the clients machine
- Web server must be configured to serve the WPAD file with a MIME type of “application/x-ns-proxy-autoconfig”
- A file named wpad.dat must be located in the WPAD Web server’s root directory.
- The host at the WPAD address must be able to serve a Web page.
- So if you are a member of example.com domain the browser is looking for this url for the PAC file http://wpad.example.com/wpad.dat
Essential tcp ip network tools, network Swiss army knife
Being a Network administrators, systems administrators we always like to have some tools handy to look into, troubleshoot or just to figure things out. There are many open source, free tools available specialized for different purposes
In this blog I shall attempt to list some of them, give a brief description and list the available platform. I prefer to run these tools from a laptop on both windows and linux platform. I also prefer to have the ability to carry them around in a pen drive in a portable format. Linux boot disks are also useful in these cases
The basic tools to check tcp/ip
Ping is the most basic tool we use to check connectivity. We also use arp to check the local broadcast domain and the arp resolution table. traceroute(linux)/tracert(windows) is used to check the path to the destination host. “mtr” is a powerful tool to view the network part for a longer period of time, usually installed as an additional package. Windows version of mtr is also available, even a portable version. One more useful tool comes mostly of out the box is nslookup (windows and linux) and dig for linux; they are very useful troubleshooting identifying dns related investigation. “whois” is one more tool useful to find out more in some ip or domain name, owner, contact authority, as number etc. Last but not the least netstat available both in windows and linux is a useful tool to find out the local network status easily. A follow the link for a detail tutorial on how to use these basic tools.

Email collaboration for enterprises and Zimbra
When we think about email collaboration/unified messaging the first things comes into our mind is Microsoft exchange, probably not because they pioneered email collaboration but because they have great success of with all enterprise segments, more importantly the end users to felt the impact of email collaboration. Microsoft Exchange Server 4.0 was released at 1996 something that could be integrated to directory services; it was probably the first competitor to Lotus notes released in early 90s.
Let’s not forget novel. In 1990 brought the release of WordPerfect Office 3.0, adding Macintosh and UNIX to the client mix and supporting multiple servers with cross-server email, calendaring and scheduling. The next version 3.1 even included remote sync.
Today’s email Collaboration / Unified messaging
Today when try to understand email collaborative software, we think about something more than email and address book. It is also called unified messaging. Enables us to share calendar events and task lists, update presence information, advanced email routing, global/corporate address book, sharing documents and other media without having to attach it, email auto responders; most importantly, access to all these through push notification support from of your favorite desktop collaboration application, mobile, tablet, or just any web browser. Email collaboration systems are also expected to be integrated with the directory services as well as other collaboration system running within the enterprise.
Things we take for granted, antivirus, anti spam, central authentication, high availability, monitoring, backup etc.
