Maybe someone should write the next REBOL killer app? Call it RING? RING -- A REBOL ping that is much smarter and tests various network protocols against a given IP address or DNS name. Even Robert Metcalf who invented Ethernet, says PING is an outdated tool/utility that was great for the days of ARPA net and the early days of the Internet, but can't someone come up with a better tool after 20 years?? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Thursday, June 22, 2000 1:37 PM To: [EMAIL PROTECTED] Subject: [REBOL] Ping Tool Re:(3) On Thu, 22 Jun 2000, you wrote: > This also points to a potentially larger problem in > that Rebol doesn't appear to handle any protocol > not based on TCP. REBOL handles UDP as well. The UDP handler that is part of Core 2.2 has a few bugs though, which were fixed in VIEW and will also be fixed in the next Core releases. Even in Core 2.2 you can send UDP packets. Receiving does not work in that version though. REBOL currently handles all protocols based on IP which work across platforms and can be supported without requiring su privileges. > The fact that using ICMP might require superuser (admin) > priveleges is a user issue only and should not affect RT's > decision to implement it or other basic socket calls. It would mean that anyone using Unix would have to either install REBOL as setuid (which would be a Very Bad Thing because it would allow any user to run arbitrary REBOL scripts with root permissions), or the use of ping and other ICMP-based functions would be restricted to the superuser (probably not a good idea either). -- Holger Kruse [EMAIL PROTECTED]
