Improve Apple Services with AirPort Base Stations

You can make iChat file transfers, iDisk, and Back to My Mac work better by turning on a setting with Apple AirPort base stations released starting in 2003. Launch AirPort Utility, select your base station, click Manual Setup, choose the Internet view, and click the NAT tab. Check the Enable NAT Port Mapping Protocol (NAT-PMP) box, and click Update. NAT-PMP lets your Mac OS X computer give Apple information to connect back into a network that's otherwise unreachable from the rest of the Internet. This speeds updates and makes connections work better for services run by Apple.

Dartmouth Releases InterMapper 2.1

Dartmouth Releases InterMapper 2.1 -- Dartmouth College has released version 2.1 of InterMapper, its versatile network management and troubleshooting tool for medium to large AppleTalk and IP networks, mentioned in Chris Pepper's recent article about firewalls (see TidBITS-468). InterMapper uses Simple Network Management Protocol (SNMP) and other protocols to provide graphical network topology displays (with automatic discovery), warnings and alarms, active monitoring of servers and routers, and much more. Version 2.1 enhances InterMapper's integrated Web server so network administrators can remotely access most of the network information available to InterMapper, serving images using speedy PNG graphics. (See "A Closer Look At Web Graphics" for more information about the PNG format.) InterMapper 2.1 is a free upgrade for owners of InterMapper 2.0; otherwise, InterMapper is available for $795 from Dartmouth College, with a 50 percent discount for educational institutions. A 2.1 MB demo version is available.

If InterMapper is overkill (or overpriced) for your network, check out Dartmouth's recently released SNMP Watcher 1.0, which displays simple tables of SNMP information on AppleTalk and IP networks. You can use SNMP Watcher to monitor your network devices over time for errors and activity, and if your users install the optional SNMP software that ships with Mac OS 8.5, you can see what applications, extensions and other software are installed on a remote Mac, which is great for troubleshooting and technical support. SNMP Watcher 1.0 is available for $99, and there is a 280K demonstration version. [GD]
