Free Anti-virus Software on ITS CDROM
by Teresa Sakata

An updated ITS CDROM is available at the ITS Help Desk in Keller 105 on the UH Manoa campus. Internet Explorer has been added to support the PeopleSoft Human Resources system, virus software for the PC is now McAfee rather than Dr. Solomon, and software versions have been updated. All members of the University community are encouraged to take advantage of this free offer from ITS. The virus protection software can be especially valuable to you by helping you guard your system against viruses. ITS has purchased a site license for the McAfee virus protection software for all institutional and personal computers. Take the time to install the software and keep up with the free updates supplied via the Web. The extra protection for your system is well worth your time.

Present a validated UH ID to pick up your copy of the CDROM. Some of the other UH campuses have pick-up locations for their faculty, staff, and students. Those locations are:

  • Leeward Community College Computer Center, BS-108
  • Maui Community College Computing Services
  • UH-West Oahu
  • Windward Community College Library in Hale Laakea

A complete listing of software on the ITS CDROM can be found at

7MB E-Mail Size Limit Implemented
by Michael Hodges and Linda Maeno

In order to improve the reliability of UH e-mail services, a 7MB size limit on e-mail messages, including attachments, was implemented on October 31, 2000. This limit affects e-mail sent from any hawaii.edu address as well as e-mail sent to any hawaii.edu address, regardless of where the message originated. For example, a 10MB e-mail message sent from a RoadRunner account to a person using Eudora with a hawaii.edu address would not be delivered.

When a message exceeds the 7MB e-mail size limit, the following error message will appear in a pop-up window of the sender's e-mail client:

"5.3.4 Error writing message - a message size of 7002 blocks exceeds the size limit of 7000 blocks computed for this transaction."

Note that 1 block = 1024 bytes = 1KB. Note also that this message will not change, regardless of the actual size of the e-mail message being sent. Members of the UH community may wish to inform colleagues not affiliated with UH of this 7MB e-mail size limit.

How big is 7MB? Normally, text in an e-mail message would not come close to this size - it would take over seven million characters to fill up that amount of disk space. Attachments are usually the cause of large e-mail messages since they can contain lengthy documents, graphics, or other media files. However, the attachment will still have to be very substantial to exceed the size limit. Note that most private Internet Service Providers impose an e-mail size limit of 3 - 5MB.

This e-mail size limit is completely different from your UNIX disk quota limit of 20MB. That limit involves the amount of UNIX disk space the files under your ITS username can occupy. For more information on your disk quota, type help file_mgmt at the UNIX % prompt.

If you need to transfer a file that exceeds the 7MB size limit, here are alternatives which will not adversely affect the UH e-mail system:

  • Compress your file. By using a utility to compress your data, you may be able to reduce the size of your file to below the 7MB limit. Compression software is available via the Web. Winzip for PC systems is available at winzip.com. Dropstuff for Macintosh systems can be downloaded from www.aladdinsys.com. Both of the compression software are free for evaluation purposes with a fee for continued use. If the compressed file is less than the 7MB size limit, it can then be sent via e-mail. If you are using Pine on the UNIX system, you will need to upload the compressed file to your UNIX account before sending it. Remember that there is a 20 MB disk space limit for UNIX accounts. After sending the compressed file, the recipient would have to uncompress the file.


  • If your compressed file is still above the 7MB e-mail size limit, or if you already have a personal home page set up in public_html on the UNIX system, it may be convenient to post your file in your Web space or on your home page for others to access. For instructions on how to do this, visit www.hawaii.edu/infotech/bigxfer.html This method is also limited by the 20MB disk space limit on UNIX accounts.
  • For further assistance in transferring large files, e-mail the ITS Help Desk at help@hawaii.edu or call 956-8883.

    This new policy on e-mail size is necessary in light of recent events where extremely large e-mail have been responsible for interruptions in UH e-mail services. One case involved a 90MB attachment that slowed e-mail services to a near standstill. In a similar event, a 100+MB attachment from the mainland was sent to a local listserv, causing downtime and extensive mail delays. The e-mail size limit will help to ensure reliable e-mail services and timely delivery for the UH community.

Media Access Generator (MAGpie):
Captioning Tool for Audio and Video Files
by Jon Nakasone

Captioning video and audio files used to be a time-consuming and difficult process, discouraging developers from captioning their media files for Web sites and CDROMs. Developers can now use a free and easy-to-use tool called the Media Access Generator, or MAGpie, from the National Center for Accessible Media at WGBH-TV in Boston.

MAGpie allows developers to make their media files more accessible to the visually and hearing impaired by adding captions and subtitles, including audio descriptions. This accessibility also extends to users who do not have sound cards or whose surroundings make it difficult to listen to media files. Providing captioning also complies with one of the Web Accessibility Initiative's priority one requirements for making Web sites more accessible for people with disabilities.

Text can be imported into MAGpie or typed in manually. In the past, developers had to go through a tedious process of typing in formatting codes and timecodes for captioning. MAGpie significantly simplifies this task. Timecodes are inserted and different options are available to change the color and fonts of captioning. The merged files are then saved to Quicktime, RealNetworks, or Windows Media formats.

To view the captioning of video and audio files, audiences may need to change the settings on the QuickTime, RealNetworks, or Windows Media players to turn on captioning. The RealNetworks G2 is the only player that allows users to hear audio descriptions in video files.

MAGpie can be downloaded from the NCAM Web Access Project Web site.


ITS Username Cleanup
by Garry Au

In 1994, when the Access For All project to provide all members of the University community with a UNIX ID was first started, there were about 8000 accounts on our ITS UNIX systems. Since then, the need for access to technology and the popularity of the Internet have increased to the point where the UNIX systems now host over 80,000 accounts. In order to provide the maximum amount of resources to those currently affiliated with the University, ITS is in the process of deleting all accounts belonging to students, faculty, and staff who have left the University system.

This cleanup of ITS usernames will be performed in three phases. In Phase I, all accounts belonging to students who have graduated or left the University will be deleted. This phase began over the summer and will soon be completed. About 18,000 student accounts will be deleted.

In Phase II, accounts belonging to faculty and staff who have left the University will be deleted. This Phase is scheduled to begin in November 2000.

Phase III involves the implementation of an automated cleanup process to delete accounts belonging to students, faculty, and staff who leave the University. This automatic deletion of ITS usernames is targeted to be in place by June 2001.

This cleanup effort will free up system and network resources such as disk space and dial-up connections to the ITS modem pool, as well as access to other services. For a list of services available with your ITS username, visit www.hawaii.edu/infotech/yourusername.html. We encourage all members of the UH community to take advantage of these services which are available for the duration of your academic or work career.
