Hello is there a command to disable with ssh the telnet and busybox ftp cause its unsecure to let ip open.....

I don't think the're started as services, so you could write an ugly but effective kill -9 $(ps -ef | grep telnetd | awk '{print $2}'). Check before executing

"Security" doesn't depend on TV but on your network

Network security is always effective if implemented in layers. Host "hardening" should be such a layer. By the way - do hosts.allow/hosts.deny work in these systems?
