However not all traffic costs the same to the ISP. I figure that international traffic is the most expensive, Israeli traffic is less expensive, and internal (ISP-internal) traffic is the least expensive. Thus an actcom user downloading a bunch of ISOs from Hamakor/Iglu's mirrors is less expensive than an actcom user downloading the same files from a remote mirror. Ditto a p2p user downloading files from an Israeli user rather than from somewher in the US. Is there an easy way to meassure "local traffic only"? How do you handle proxied traffic such as SMTP? -- Tzafrir Cohen | [EMAIL PROTECTED] | VIM is http://tzafrir.org.il | | a Mutt's [EMAIL PROTECTED] | | best ICQ# 16849755 | | friend ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
