Commands tagged nmap; (1)

  • In the field, I needed to script a process to scan a specific vendor devices in the network. With the help of nmap, I got all the devices of that particular vendor, and started a scripted netcat session to download configuration files from a tftp server. This is the nmap loop (part of the script). You can however, add another pipe with grep to filter the vendor/manufacturer devices only. If want to check the whole script, check in http://pastebin.com/ju7h4Xf4 Show Sample Output
