Bug Description
I posted this on the Ubuntu-MATE bug report before this (https:/
When I do a scan of my local network via the command arp-scan --localnet, I find that the IP of the machine which has Ubuntu-MATE on it shows up in the list of IPs brought back by arp-scan. But when I ssh to that machine and then issue the command arp-scan --localnet from the machine that I had sshed from, I find that the IP address of the computer with Ubuntu-MATE on it is absent from the list. I expect the IP address with the machine with Ubuntu-MATE to show up. I tested this with other machines and operating systems and those still returned an IP address when issued arp-scan --localnet. The Ubuntu-MATE machine was the only one which didn't.
