Model Identifiers are used to highlight which model a particular device is.There are some other identifiers that you might come across, as well. Invest in your career.You can also copy the UUID directly from within iTunes. If you run it with an IP address as an argument, such as ". I am about to convert 10.97.2.31 into hex: When you run this script, it will display this output: & echo "You asked for $1 which is `ip_to_hex $1`"Įcho "I am about to convert 10.97.2.31 into hex:"Įcho "$IP_ADDRESS = `ip_to_hex $IP_ADDRESS`" You can use this function to convert the data in any way you like: convert_ip_to_hex.sh This is useful, because printf, when called as " printf '%02X' 192 168 1 47" will take each of the four arguments, and print them as uppercase hexadecimal strings (as instructed by the '%02X' formatting instruction). The " $" means to transform the first (and only) argument, known as " $1" (eg, "192.168.1.47"), and convert periods to spaces. However, this little function will do it for you: It's possible to sit down with a Hex Calculator (there are many online, mobile apps, etc), and work out each one. So you need to provide files in the /var/lib/tftpboot/pxelinux.cfg/ directory, with names like C0A8012F. The conversion looks like this: Decimal IP Address
However, it asks for these in hexidecimal format, which is a bit of a pain if you don't happen to be 100% fluent in all hex values between 0-255. Typically, they will be instructed to download pxelinux.0, which will be passed to the CPU, and result in the client requesting a further file, either the BIOS UUID, or if that fails, then the client MAC address, or if that fails, then the client IP address (which it retries with ever-reducing accuracy: 192.168.1.47, then 192.168.1, then 192.168, then 192). They get their IP address by DHCP, which also sends them extra information - specifically, the IP address of a boot server, and the name of a file to request from the boot server. PXE Boot is a great way to install clients over the network. 11th October 2016 Convert IP Address to Hexadecimal
