Note: you should start the Dude from the root user (or delegate some permissions to your regular user), or else the Dude will not be able to ping hosts. Local mode - this option will not work for Linux users running the Dude under Wine, you should use remote connection to 127.0.0.1 host instead to connect to the local Dude server. Remote connection by default uses TCP port 2210 for regular mode, and TCP port 2211 for secure mode, so make sure these ports are not limited by a firewall. The ports may be changed in the server's Global Settings menu. The default username for connecting to a server is “admin” with no password. You can change this later
I still have problem with dude discovering my devices, i am able to login with 127.0.0.1 or even the ip on the ubuntu server, but when i click discover…it goes on without discovering anything…did i miss something?
I have enabled snmp on my router as shown bellow:
