actually, "host not found" is a failure to resolve the host name (by DNS and netbios). While setting PingCmd to /bin/true (or "&{sub {0}}" if you prefer saving a fork and don't mind cryptic code ;-) *will* resolve the issue (if not the host name), it also makes backups fail instead of not being attempted when the host is actually down. That might not be a problem - I believe BackupPC handles retries in the same way - but it will mess up things like your blackout schedule. The list of possible solutions is long, with the simplest being to add a line in /etc/hosts on the BackupPC server for the machine in question. If you have a DNS server on your network, you'd rather add it there, which may be slightly more complicated, but will give you network wide (consistent) resolution of the host name. Other than that, there's the Windoze way of getting the WINS server setup right (smb.conf on the BackupPC server) or, possibly, matching up the host name you use in BackupPC with what the host itself thinks it is called. Setting the domain/workgroup to match is also a good idea :). If your Windoze client is named "windozebox" (as far as BackupPC is concerned) and has the IP 1.2.3.4, your /etc/hosts line would be something like: 1.2.3.4 windozebox.yourdomain.com windozebox (both tabs and spaces should be accepted, use whatever other entries use). In any case, the /etc/hosts entry is the easiest way to try out what happens when name resolution is working (*). You might then run into the issue Les is referring to (ping denied by Windoze firewall). Hope that helps. Regards, Holger (*) 1.) Theoretically, it is possible to configure a Linux system in a way that /etc/hosts is *not* be used for name resolution, but it usually is not set up that way, and even if, I'm not sure all commands actually honour that configuration ;-). 2.) I'm assuming your Windoze box has a static IP. If it gets a random IP via DHCP, you can still *test* what would happen by creating an entry matching the *current* IP assignment (and deleting it again after testing!). For production use, you would then need to either have the Windoze host register its IP with the DNS server, use a combined DHCP/DNS server (like 'dnsmasq'), or use netbios for name resolution. That will likely involve using a WINS server, assuming your Windoze host is on a different network segment than the BackupPC server (I'm guessing that otherwise things would already work). ------------------------------------------------------------------------------ Comprehensive Server Monitoring with Site24x7.
