We are using PowerWare 9125 UPS, and PowerWare does not have FreeBSD version of UPS monitoring software. They have Linux version which worked very good on FreeBSD 4.X. PowerWare soft has two parts: daemon, which monitors UPS, and client (there are text mode, GUI for X11 and GUI for Windows versions). They use UDP for communications. If I try connect to ls3 (daemon) which is running on FreeBSD 5.4-STABLE, then I get message about timeout from client part (ls3con). I see UDP packets from client to server with tcpdump on lo0 interface (with local client) or on fxp0 interface with remote client. But server start responding after 30-50 seconds. ls3con does not see server responses and gives error message about timeout. With command line client it IS possible sometime connect to server if I start client after error message, and if client uses same local UDP port as before, then it gets _previous_ server response. Then they estabilish TCP connection and all works OK. With FreeBSD 4.X there are no any timeouts, server responds fast enought for client to see response. To be sure I have tried this with server in remote office, which I have not upgraded yet. So, does anybody have same problems? I think, that problem may be in LanSafe application, but ... Also, maybe anybody knows other software which will work with PowerWare 9125 UPS? This UPS is not supported by NUT.
