When you have 100+ routers or servers you manage, it is a bit tedious to make a configuration change to all of them manually, especially when that change is exactly the same for all of them. There is tons of software for this scenario. I have used a few different ones in the past, but parallel-ssh (formerly pssh) is what I use for Mikrotik. Example: Need to enable and set primary and secondary ntp servers on 100 devices. First you need to create a text file with all your devices IP addresses, and optionally port and username. 10.10.10.1:22 10.10.10.2:22 10.10.10.3:22 save it as ips.txt for instance, and use the command bellow to blast commands to all listed devices. parallel-ssh -l admin -x "-o StrictHostKeyChecking=no" -A -h /home/sam/ips.txt -v -t 10 -o /home/sam "/system ntp client set mode=unicast enabled=yes primary-ntp=1.2.3.4 secondary-ntp=1.2.3.5" Explanation: -l Specify the user here instead of txt file -A Prompt for password
