linuxconf/Dhcp configuration/one subnet definition Network number 172.16.0.0 netmask 255.255.0.0 IP range start 176.16.1.0 IP range stop 176.16.1.255 When accept is clicked, linuxconf reports: Invalid host IP number 172.16.1.0 True, this number is an invalid class C address, but it is a perfectly valid class B address, which is indicated by the netmask setting. Setting the start address to x.x.x.1 and stop address to x.x.x.254 serve as workarounds.
It may be a perfectly valid class B address, but it still isn't in the range you've specified - note your network is *172*.16.* but the address is *176*.16.* instead...
Somebody can't type - me !!! Network is 172.16.* Range is 176.16.* 172 != 176 Does that help?
rhw is right, this is not a bug. Thanks!
