Hi all, my router has a recent kernel but some very old userland, it's libc4 and libc5 based. I managed to find a libinet6.a contained in inet6-apps-0.34 that I could compile. The ping in that package works. But I cannot find a radvd that can be compiled with libc5 and libinet6.a. The main problem seems to be the different #define names that changed when the ipv6 stuff made its way into glibc. A statically linked radvd for glibc doesn't work because even statically compiled binaries want to load libnss.so dynamically. Anyone who has a running radvd for libc5? Regards Holger
