[REBOL] Re: Ping?

From: doug:vos:eds at: 9-Feb-2001 15:54

... so here is a "way to ping with REBOL..." 1. REBOL writes the batch file 2. you run the batch/shell file 3. the last line in the batch file calls next REBOL script... ;------------------------------------------------------------ This script will ping every static IP address in a DHCP tab file to see if the device is still there. Then the DHCP admin can clean up DHCP for devices that have been shut off or moved to a different LAN segment.... It works by creating a batch file (.BAT) You could modify it for other platforms... eg. UNIX/LINUX shell The main guts of the script is the following few lines: { fwrite rejoin [ {echo. } ip/host-name { > } fname newline {ping } ip/ip-addr { >> } fname ] } It creates a file of ping results for each device, like %/ping-result-path/ If you want the other files, that go along with this let me know...
