FYI, Look at this old patch/workaround in asterisk which solved the problem with daemon() and uClibc.

Will not runin the background. Thanks for the tip! I have uClibc 0.9.28, which dates back to 2007, so it might very well be the problem. I have tried to build it from recent sources, but ran across i a lot of minor issues concerning the unusual layout of the device (I do the compiling ON the device itself). But I'll try some more, or maybe I'll just try the daemon function in owlib instead. I'll be back later and report what happens.

Will not runin the background. I guess your uClibc version contain a bug which result into a non-working daemon() function. (since it call wrong fork() function). Do you know exactly which UCLIBC version you have? There is a workaround to define the daemon() function within the owlib, and that might be possible for you. Otherwise you probably need to patch uClibc and recompile everything for your NAS. The old bug in uClibc is caused by a faulty libc_hidden_proto to fork(). +--- uClibc.org/libc/unistd/daemon.c 2009-07-14 11:09:20.000000000 +0200 ++++ uClibc/libc/unistd/daemon.c 2009-08-06 10:21:57.000000000 +0200 +@@ -54,7 +54,7 @@ + libc_hidden_proto(dup2) + libc_hidden_proto(setsid) + libc_hidden_proto(chdir) +-libc_hidden_proto(fork) ++/* libc_hidden_proto(fork) */ + + int daemon( int nochdir, int noclose ) + { /Christian From: Paul Alfille [mailto:paul.alfi...@gmail.com] Sent: den 6 mars 2010 22:06 To: OWFS (One-wire file system) discussion and help Subject: Re: [Owfs-developers] owfs (owserver) on DNS-323.

Like the WRT54G, but with a lot more storage. Any idea what distribution you are using? Especially what C library. It looks like the handling of glibc and uclibc on matters like fork and daemon are different. I downloaded owfs-2.7p28 and ran ./configure and make install, and hey! It compiled with no errors! I then tried to run owserver with a test adapter. It started three threads in the background that I can see with ps ax, but owdir shows nothing. Then I tried running owserver in the foreground, and that works fine! It works nicely with -u and owget gives me the temperature on a connected sensor. (I haven't got Fuse, so I don't intend to run owfs. Configure detected this nicely.) I see a line of code in owserver.c, saying something about special treatment of exit() on the wrt54, compiled in with the macro __UCLIBC__. Perhaps this is needed on the DNS-323 too. I do have uclibc on the machine, but I am not sure if the library path is set correctly. And I can't see anything in ./configure or the Makefiles referring to this macro. The code to go into the background is in modules/owlib/src/c/daemon.c Does anyone have any ideas on how I can go on debugging? I tried running with verbose output redirected to a file, but when running in the background I don't get any output at all.
