I want to check if certain clients connected to my HDA are active, using ICMP Ping. I can ping the IP addresses, but I can't ping the hostnames. arp -a delivers:
Code: Select all
h033.home.com (192.168.0.33) at 6c:f0:49:df:02:9b [ether] on eth0
h145.home.com (192.168.0.145) at 00:1b:11:4c:25:df [ether] on eth0
h101.home.com (192.168.0.101) at <incomplete> on eth0
h098.home.com (192.168.0.98) at 00:1e:64:3f:c1:74 [ether] on eth0
How can ping my clients using the real hostname, which are also shown when I open "Places - Network" in Fedora?
Another approach I'm considering is using the MAC addresses rather than the host names. This will be a safe way to identify clients, however it's not very user friendly (and I haven't figured out yet how to request a remote MAC address...)
Thanks for your help,
