Hi Sasha, When I now build OpenSM, I get the following error at link time: opensm-osm_console_io.o(.text+0x245): In function `is_authorized': osm_console_io.c:134: undefined reference to `hosts_ctl' I think hosts_ctl comes from libwrap but I don't see that as part of what the link includes. What am I missing ? Thanks. -- Hal
