14. Overlook Fing (Free)
If you do any networking work, this is a must-have app. It can do TCP port scanning, pinging, traceroute, and DNS lookups on a network via Wi-Fi. It also shows the network details (SSID, IP details, and speed) of your current Wi-Fi connection.
You can see and export the details (MAC address, IP and vendor) for each computer or device detected on the network, which are customizable with a name, icon or notes. You can also perform a port scan or ping a particular computer or device. It can also launch third-party client apps for SSH, Telnet, FTP, FTPS, SFTP, SCP, HTTP, secure-HTTP and SMB.
15. RouterPasswords (Free)
This is a must-have for anyone that works with networking gear. It's a simple database of the default login methods and credentials for over a thousand routers, gateways, modems and other network components. Though you can find the same info online, this gives you quick off-line access. Just start typing the model or brand and it will begin list matching entries.
16. Linux Commands (Free)
If you use Linux but aren't an expert at the command-line, this is a great app to have for reference. It lists more than 500 Linux commands that you can browse through. Select a command and you'll see the syntax, description, and any command options. You can even star your favorite commands and have them shown at startup and/or manually access your list of favorites. Though you can find the same info online, this gives you quick off-line access.
