Disable TCP and UDP small servers

OrtaDüzey 1Otomatikcisco-iosxr

Açıklama

TCP and UDP small servers are servers (daemons, in Unix parlance) that run in the router which are useful for diagnostics. TCP Small Servers The TCP small servers are: Echo: Echoes back whatever you type through the telnet x.x.x.x echo command. Chargen: Generates a stream of ASCII data. Use the telnet x.x.x.x chargen command. Discard: Throws away whatever you type. CIS marks this Manual; automated as a config-line check. Audited against the hierarchical output of 'show running-config' (run 'terminal length 0' first; not 'show running-config formal').
