Re: skype and voip questions
HI Amos It seems that the iptables rules are cut. Can you post the whole lines here? Probably when you cut and paste from nano/pico this happened. Supernode is on what port? I had 32323 and changed it now to other non standard port. On Fri, Jun 13, 2008 at 4:06 AM, Amos Shapira [EMAIL PROTECTED] wrote: 2008/6/13 sara fink [EMAIL PROTECTED]: What traces you ran? I need to solve it. They are pulling on me all the nasty things. tcpdump? or other things? Almost two years ago I was bugged by the skype uses too much traffic claim and setup iptable rules to track this (I used to have Skype on Linux in Supernode mode because it improved connectivity and quality a lot, I haven't bothered to set it up again after re-install and ADSL modem upgrade). Here is the summary of how I setup the iptable rules: http://praia-vermelha.blogspot.com/2006/09/final-iptables-setup-and-some-initial.html I generally remember that got the impression from the results that Skype doesn't use too much traffic for my ADSL link (8Mb/1Mb back when I ran this test). We use Skype between Israel (NetVision)/US/Brazil/Australia, including webcams, with no problems at all. Both on Windows and Linux and both from home and office. The latest versions for Linux improved reliability a lot.
