Несколько систем с тем же IP/подсетью
Необходимо смочь к клуджу это путем создания символьной ссылки для недостающей зависимости:
sudo ln -s /usr/lib/libcurl.so.4 /usr/lib/libcurl.so.3
Однако можно получить больше этих проблем зависимости, пытающихся устанавливать более новые пакеты, такие как Мерзавец на такой старой версии Ядра Fedora. Действительно ли Вы не можете обновить?
If they're hard-coded with a single IP address then other than per-port VLANing and routing/NATing you're going to run into a lot of problems. They won't cause problems from a switching perspective as IP is L3, but they will cause problems for routing.
Can you not just set them to use DHCP? The MAC is already a GUID of sorts. If needs be you could then script a more permanent IP change from that point.
You say "broadcasting a command" to change the ip address. Is this something the devices already implement or something new? If all these systems are in 1 subnet it is "possible" but would require a lot of layer 2 programming skills. Remember, a host isn't going to keep a list of MAC addresses it has seen for "no reason". Essentially, you would need to write a ton of code and have it all operate at a very low level in the host.
