Hi, I have a rogue dhcp server on the network and can not find it.With wireshark i found an ip and mac address, i can not ping the ip or connect to it. When i look on the cisco switch the mac adress is on a port connected to the proxmox server. On this port i have 4 mac addresses, 2 of vm's and 2 i do not know. I checked, they are not vm mac addresses, i checked all the vm nics. I also checked in linux with ip -a. and to no avail. Is it possible the is some hidden server? Or dhcp service on the proxmox linux?
