All,
i am trying to find a way to verify that the TFTP service is not running on the router. i issued the no tftp-server flash: <ios> and it accepted it even though it does not show up in the show running config. any docs would be helpful.
Solved! Go to Solution.
If the command isn't in the running config, it's disabled. The tftp server isn't turned on by default. There are version differences that seem to either support the control-plane command and those that don't. I have a 3845 that has it, but I have a 3825 that doesn't. Here's a 3745 that does that would show you the results should you decide to maybe update your router:
R1#sh control-plane host open-ports
Active internet connections (servers and established)
Prot Local Address Foreign Address Service State
tcp *:23 *:0 Telnet LISTEN
udp *:69 *:0 TFTP-Server LISTEN
R1#
HTH,
John
If you have the command, you can do:
sh control-plane host open-ports

no i do not have that command available. its a 3800 series router.
sh ip socket will show me the ports is listening on but, i was looking for a doc that states that by default the TFTP service is disabled and how to verify that it is not running.
