net-analyzer/mtr doesn't wait for last packets sent out in report mode and exits immediately, causing erroneous packet loss to be reported. This issue has been fixed upstream with https://github.com/traviscross/mtr/commit/6ce1601
Created attachment 373240 [details, diff] 0.85-timeout.patch Tested the patch (made from the github commit) and it has fixed the bug in question, and been quite stable for the last few months that i've been using mtr.
Comment on attachment 373240 [details, diff] 0.85-timeout.patch So this is fixed already in 0.85_p20140126?
Yeah, that ebuild already contains the fix. :)
