Maybe I'm missing something here. But won't simple multiplication do this for you? 10Gbyte = 10*(1024^3) = 10737418240 bytes 1 month = 30 days/month * 24 hrs/day * 60 min/hr * 60 sec/min = 2592000 seconds 10737418240 / 2592000 = 4142.522 byte/sec So if you want to transfer 10Gbyte in a month your channel better support at least 4Kbytes/sec. Since most data comm equipment is rated in bits/second you need a channel that supports 32Kbits/second. So your average 56K dialup might just work. -- Chris Fedde To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
