I'd guess that he just got the binaries from Entware-ng, and doesn't have a toolchain to compile it himself. If he could recompile, it would certainly be helpful to test that. My thought is that there might be a problem with running the modern code on the old Tomato firmware (last release was something like 2010). Looking at the code of fwknop, it looks like it's dying on just the fdopen() call. Unfortunately we aren't actually catching the error from fdopen, just that it is returning null. That fdopen() call is acting on pipe_fd[0]. I don't see that pipe_fd[0] is ever given a value after being defined. I haven't dove deep in this code yet, but that looks suspect, at least. xrak, what device are you running this on, the WRT54g? It might just be a simple memory exhaustion problem if it's one of the old routers with only 16 megs of ram. --Jonathan > > Thanks, > > Mike > > >> Can anyone let me know what could be causing this problem? >> >> ------------------------------------------------------------------------------ >> Site24x7 APM Insight: Get Deep Visibility into Application Performance >> APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month >> Monitor end-to-end web transactions and take corrective actions now >> Troubleshoot faster and improve end-user experience.
