Does Mikrotik RouterOS script has random option? For example, /ip hotspot user print , Print all users in hotspot. Is there way to print one user at random?
No, direct random command does not exist, however, you could try messing with memory, hard disk space, cpu load, interface speed/packets, etc... to get a kindof-sortof random number.
I saw something in the Wiki about if for passwords awhile ago, it may be worth checking there as well.
