Swiss army knife treats for tool lovers

. What's this?

We love tools, whether they are hardware or software. We suspect it is something to do with that Tim Allen guy thing. Anyway, a few tools have landed on our desks with a delightful thud and we decided we needed to share them.

First up are two updates from Tsarfin Computing: NetInfo 4.9 and IPMonitor 4.9. We mentioned NetInfo some time ago, and while it is essentially the same tool it has been polished.

NetInfo is a Windows 95/98/ME/NT/2000/XP/2003 Swiss army knife kind of utility that provides a suite of functions for discovering TCP/IP network information. Presented with a tabbed interface - one for each function - NetInfo provides tons of useful information.

There's local info (such as host name, user name, media access control address and IP address); connection data (active socket addresses, protocol, address connected to and socket state); ping; traceroute; lookup (which returns forward and reverse DNS lookups, lists aliases and provides mail exchanger or MX records); finger; whois; daytime (time from other network hosts); time (time from time servers); and quote of the day. And you can retrieve raw data, including the header, from a URL.

NetInfo also can scan an IP address range for hosts; scan a host for active sockets; test an e-mail address; and, as if that weren't enough, once you register the software (for a mere $25 for home use and $50 for enterprise use) you can use the online services of what Tsarfin calls the Web Center.

The Web Center is a collection of news services and tools. Many of these duplicate the functions of the local tools but run on remote servers. This is useful for problems that make you wonder if whatever is wrong with a machine or service causing you trouble is just wrong from where you sit.

Back in the application you can select and send URLs, IP addresses and host names from one feature to another. You could run a traceroute, select one of the hops and send that to the lookup function. You also can export data to Web pages but (and this is our only complaint) you can't copy the data to the clipboard.

The other Tsarfin tool, IPMonitor, is priced identically to NetInfo (you also can buy the two bundled for $40). IPMonitor, which, like its sibling, runs under Windows 95/98/ME/NT/2000/XP/2003, can keep tabs on the health of up to 500 network devices or services using TCP, User Datagram Protocol (UDP) and Internet Control Messaging Protocol, and although IPMonitor is simple to use, it is really quite powerful.

It can run as a system-tray application that is loaded on start-up, support customized alerts for each monitored resource, raise audible alarms, send e-mail alerts and run other applications when server outages are detected. It also provides real-time reporting and status logging.

Again, we have a complaint - we'd like to be able to establish hierarchical relationships between monitored hosts so that if, for example, our gateway goes down and generates an alert, any other hosts we monitor that are accessed through that gateway don't also raise alerts.
