Installing TFTP server

This step is not mandatory and since most of you are now excited from accessing your Cisco device probably you don’t even read these lines ;). But believe me in some point you will come back to read the rest because with a TFTP Server you will be able to copy files from Cisco Switch / Router to your computer. So lets setup the TFTP Server:

sudo apt-get install tftpd-hpa

Configure TFTPD

edit the configuratoin file with your favorite editor:

sudo nano /etc/default/tftpd-hpa

and make it look like the following:

TFTP_USERNAME=”tftp”
TFTP_DIRECTORY=”/tftp”
TFTP_ADDRESS=”0.0.0.0:69″
TFTP_OPTIONS= “–secure –create -v –ipv4”

Note!! The last line of this file contains “double dash” before secure, create, ipv4.

You can download the file from here:

Lets create the Directory for our TFTPand give the appropriate permissions :

sudo mkdir /tftp

sudo chown -R nobody:nogroup /tftp

sudo chmod 777 /tftp

now lets restart the tft Server:

/etc/init.d/tftpd-hpa restart

And Check your current ip by typing:

ifconfig

This is also the IP of your TFTP server

Copy Configuration files from Cisco to TFTP

Now Go back to your minicom session and type the following:

to enter the enable mode:

enable

type the enable password if need it and then check the flash contents by typing :

dir flash:/

Now lets copy the config.text to TFTP but before that lets check that your switch can communicate with your computer. In order to do that you must have a network cable connected from your computer to your Cisco Switch /Router. and also the port that is connecting your computer to the switch must belong to a vlan that has an ip address in the range of your computer’s ip. so lets ping your computer from the Cisco:

In my case my Computer has the IP 192.168.0.202 so the command will be:

ping 192.168.0.202

the output should look like the following:

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.0.202, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/3/10 ms

Now you are ready to copy files from Cisco To TFTP

copy flash:/config.text tftp:/
Address or name of remote host []? 192.168.0.202
Destination filename [config.text]?
!!
1773 bytes copied in 0.076 secs (23329 bytes/sec)

Now the config.text should be in your local folder /tftp

Have Fun.
