There are several listening sockets on the management interface, as output form

show ip sockets


The listening port numbers are 67,68,2228.


I do not know what is being used on these ports. DHCP is handled by another machine. 2228 i have no idea, but either of them could be used as a catalyst for any traffic.


How do i shut these off??

67 udp bootstrap protocol server. listening port on bootp & dhcp servers. clients broadcast to it for boot or network parameters. security concern: can probe nis domain name; plus a valued dos target

68 udp bootpc.'bootp/dhcp client; bootstrap protocol client'.

ehome-ms Port 2228 TCP eHome Message Server

ehome-ms Port 2228 UDP eHome Message Server
