Tftp server on procurve switch?


I have noticed that you can disable a tftp-server service with the command "no tftp server", but what is the reason for the server to be started by default?

What can it be used for? Can I download something from the tftp server? Os image or configuration files?

Yep, it can be handy when copying the running flash image from one switch to another... copy tftp flash flash pri|sec

Thank you for your reply!

So I can download the os image, but not the running/startup configuration?

(Since the lack of authentication in tftp that would not be nice.)

Anyway, would it be recommended to turn the tftp server off if I do not intend to use it?

Re: Tftp server on procurve switch?

try the following (from 9300 manual):

USING THE CLI
To initiate transfers of configuration files to or from a TFTP server using the CLI, enter one of the following
commands:

copy startup-config tftp
- Use this command to upload a copy of the startup configuration file from the Routing Switch to a TFTP server.

copy running-config tftp
- Use this command to upload a copy of the running configuration file from the Routing Switch to a TFTP server.

copy tftp startup-config
- Use this command to download a copy of the startup configuration file from a TFTP server to a Routing Switch.

Thank you Steven for your reply.

I do think the command you have mentioned however is for the tftp client on the Procurve switches, and I was looking for some information (and potential danger) with the built-in tftp server.

By default the TFTP is 'secured' in that you cannot copy startup/running-config from it. You can un-secure it by setting a particular SNMP OID (this is how I believe PCM+ copies over the configurations when using TFTP). Once it has copied it over, it secures it again.

Re: Tftp server on procurve switch?

If I wanted to use a 3rd party tool to back up the switches, how can I set this OID so that I can back the switches up?

 

Otherwise, I end up with an 'access violation'
