I want to do some network stress/burn-in and quality/reliability testing, i.e. i want to send/receive large amounts of data trough the systems network interfaces without the need of hogging the net or other systems. so, that test should run "loopback", i.e. connecting eth0+1 via crossover cable or via locally attached switch. I don`t want to use a second system for that. testing at ip/tcp level would be favourable , but raw eth level would be also fine. But how ? What appears simple on a first view, seems to be difficult.... :( All i came across is this report: http://www.zyztematik.com/?p=10 and this description of a patch: http://www.ssi.bg/~ja/send-to-self.txt Does somebody know a proper way of achieving this without patching the kernel ? regards Roland ___________________________________________________________ SMS schreiben mit WEB.DE FreeMail - einfach, schnell und kostenguenstig.
