One of the easiest ways to copy files from a Cisco IOS switch you don't have the ability to make changes on is to send files using TFTP.

Here is how you get TFTP Server installed, up and running on your reliable Ubuntu Server.

sudo apt-get install xinetd tftpd tftp


sudo nano /etc/xinetd.d/tftp

ADD to this new file:

service tftp

{

protocol = udp

port = 69

socket_type = dgram

wait = yes

user = nobody

server = /usr/sbin/in.tftpd

server_args = /tftpboot

disable = no

}

CREATE directory

sudo mkdir /tftpboot

sudo chmod -R 777 /tftpboot

sudo chown -R nobody /tftpboot[/code]


ADD to startup

sudo /etc/init.d/xinetd start

This is how I copy Cisco IOS images to the TFTP server

copy flash: tftp:

c2500-ik8s-l.122-5.bin (name of image file to backup)

10.6.56.244 (IP address of remote TFTP server)

c2500-ik8s-l.122-5.bin (name of image file to use on TFTP server)

Having issues with xinetd TFTP Server.

Here are some options and note if you uninstall one, you have to reboot your server before installing the other since Ubuntu locks the TFTP UDP port 69 and I found that a reboot of the server is the only way to get it to release.
