I have upgraded to CentOS5 on our computers. I had been using Mandriva 2006. The problem I am having is that the networkupstools (nut-2.0.4.tar.gz) does not find the UPS device. However, when I had Mandriva 2006 on the same hardware it worked. The device manager on CentOS does show the UPS device. The settings I used in the ups.conf file are: driver = newhidups port = auto Using the same version of nut with the same config files on CentOS5, I get the following output from 'upsdrvctl': Network UPS Tools - UPS driver controller 2.0.4 Network UPS Tools: New USB/HID UPS driver 0.28 (2.0.4) No matching USB/HID UPS found Driver failed to start (exit status=1) The following libusb files are installed: libusb-0.1.12-5.1 libusb-devel-0.1.12-5.1 Using ./configure --with-user=ups the lines for libusb show: checking for libusb cflags... checking for libusb libs... -lusb I posted this problem to the mailing list for the nut software. The conclusion is that the nut software is setup correctly. I also downloaded and installed the latest version (nut-2.0.5.tar.gz) and got the same result. All UPSs are Belkin F6H375-USB. I have searched the internet and found no other solutions. Since the software works under Mandriva 2006, I would presume that there is a package that is installed by default on Mandriva that is not installed by default on CentOS or that a config file is setup differently. Any help will be appreciated, David _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
