    DHCP leases and connected clients

    Sometimes I check how many leases DHCP has issued using this command. cat /var/lib/misc/dnsmasq.leases | wc -l That doesn't really tell me if those clients are connected or not. So, to check how many connected clients I have, I try this: arp -a | awk '$4!="<incomplete>"' | wc -l The thing is...

    Someone MAC spoof and access my Network? Double ARP with diff IP Range

    So I'm currently troubleshooting my ISP's proprietary router (which I believe is built around a Cisco ME 4600, I found that the CLI commands are similar) due to a problem with the 2.4GHz signal, which stops responding after a few days. After trying everything (different channels, SSIDs etc) I'm...
