  1. Internet Technology Updatefor ICCM 1997 We do email, we use a Web browser to surf... What else is the Net good for?

  2. Introduction • Everyone is talking about the Internet • Most are actually using it! • Email is wonderful • WWW surfing is fun (sometimes useful too) • Assuming we have already done that... what now?

  3. Five Main Areas of Promise • Enabling Effective Collaboration • More Secure Communications • Directories • Increasing Integration of Tools • Giving users (only) what they want

  4. Enabling Collaboration • Shared Databases • Keyboard chat • Audio • Video • Teleconferencing

  5. Shared Databases • We can pass around floppies or CD-ROMs • Or, we can put databases on the Internet • Allows access from most places • Can allow update from most places • Well known browser interface makes it possible for users to view ‘reports’ easily • But isn’t super easy to do (yet)

  6. Keyboard chat • Can be on WWW (Java-based, etc) • Can be IRC • Can be MOO/MUD/VR based • Can build a real sense of friendship and collaboration • Can allow real time decision making when needed

  7. Audio (HOT!) • Phone calls using the Net (free int'l calls!?) • Friendlier than email for many cultures • No computer needed -- just a phone • A lot of commercial interest already • Audio conference calling also possible over the Internet • Tech support use shows promise too • See http://www.pulver.com and http://www.von.com

  8. Video and Teleconferencing • For when you need to see the other person’s face “almost like a real meeting” • Workable (mostly) over 28.8 modem connections • CU-SeeMe current popular client (Windows or Mac). Shareware. In use for ICCM! • Audio + video + kbd chat + shared whiteboard = decent expressive power • Not hard for normal Win95 or Mac users • See http://www.cuseeme.com • Netscape and MS both have similar technologies

  9. More secure communications • IPv6 -- designed to include auth and crypto • S/WAN. Packet level encryption for today • SSH - Secure shell. Works now! • PGP - application level. Works but hard

  10. IPv6 - next generation security • IPv6 is the next Internet packet format, specified in RFC1883. It mandates the ability to do good authentication and encryption at the level of each packet. • User doesn’t have to do anything special • Not here yet, except for a few experimenters on the 6-bone • Will be a normal part of your OS soon (Win98.5 anyone?)

  11. Secure/Wide Area Networking • Using the IPv6 technologies of packet level encryption, but on today's (IPv4) Internet • Has support of EFF, John Gilmore • Can be done now using commercial routers, or Linux boxes as routers, between two LANs • Has ‘FAX effect’ -- the more people use it, the more useful it is, so more people use it! • http://www.cygnus.com/~gnu/swan.html

  12. SSH (Secure SHell) • Unix freeware to do encrypted remote shell access • Then added tunnels for any TCP port • Now $99 commercial Windows 3.x/95/NT and Mac clients exist: F-Secure by F-Prot • It works, we use it at MAFxc and at FEBC • User has per session work, not per msg. • http://www.cs.hut/fi/ssh/

  13. Directories • How to organize and find things and people • LDAP is where everyone is headed (NT 5.0, Novell, Unix (slapd, others)... already in Netscape browsers and servers) • More than an online phone book • Can be updated by individual users and kept in sync worldwide • Distributed, not one central directory! So each organization can maintain their part. • http://apt.activevoice.com/ldap/ or http://www.umich.edu/~rsug/ldap/

  14. Integration • All these technologies... lots of clients? No! • One browser does it all • MS IE 4.0 extends browser to far beyond just surfing HTML pages on the WWW -- one way of handling both local and remote information and interaction with it • NetScape 4.0 is another ‘Swiss Army app’

  15. Giving Users what they want • Today’s Internet is soooo big • Users have to ‘go find’ what they want • The ‘push’ model reverses that • PointCast customized news pages are good examples. • NWfusion (techie example) another example, merging email and WWW well

  16. Summary • The Internet is more than just email and HTML • Voice communication is my hot pick for a growth area in Internet use • Greater collaboration, security and integration are also coming soon (now?) • Better ways to find stuff are needed • Let’s use these technologies where appropriate to build God’s Kingdom
