[*] the confusing part is that the other NUT command line tools aren't affected. Was the CGI program installed from the Debian nut-cgi package? Or was it built from source, or copied from the other Pi? You should get output similar to this from ldd (this is from an amd64 Ubuntu system, so details may differ, but consider overall structure): $ ldd /usr/lib/cgi-bin/nut/upsstats.cgi linux-vdso.so.1 (0x00007fff1a99b000) libupsclient.so.4 => /lib/x86_64-linux-gnu/libupsclient.so.4 (0x00007eff6ebec000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007eff6ebc9000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007eff6e9d7000) libnss3.so => /usr/lib/x86_64-linux-gnu/libnss3.so (0x00007eff6e888000) libssl3.so => /usr/lib/x86_64-linux-gnu/libssl3.so (0x00007eff6e829000) libplds4.so => /usr/lib/x86_64-linux-gnu/libplds4.so (0x00007eff6e824000) libplc4.so => /usr/lib/x86_64-linux-gnu/libplc4.so (0x00007eff6e81b000) libnspr4.so => /usr/lib/x86_64-linux-gnu/libnspr4.so (0x00007eff6e7db000) /lib64/ld-linux-x86-64.so.2 (0x00007eff6ec29000) libnssutil3.so => /usr/lib/x86_64-linux-gnu/libnssutil3.so (0x00007eff6e7a8000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007eff6e7a2000) If any of the libraries don't have a path after "=>", that's something to investigate on the working Pi (e.g. "dpkg --search libnss3.so <http://libnss3.so/>" to see which package provides that library) - Charles _______________________________________________ Nut-upsuser mailing list [email protected] https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
