Verifying TFTP on a UNIX System

Use this procedure to verify that TFTP is working correctly on your UNIX host.

Note: This procedure, which uses a TFTP transfer of the Digi Device's boot image between two UNIX hosts, enables you to compare the size of the boot image before and after it is transferred, enabling you to determine if TFTP is working properly.

Procedure

1.Access a root prompt on the UNIX host.

2.Make sure that you are not in the /tftpboot directory.

3.Enter this command: tftp ipaddress

where ipaddress is the IP address of the UNIX host. A TFTP prompt appears.

4.At the prompt, enter the following command: binary

5.Enter this command at the TFTP prompt: get tftp_file_name

where tftp_file_name is the name of the Digi Device's boot image in the /tftpboot direc- tory.

6.Enter this command at the TFTP prompt to exit TFTP: quit

7.Compare the size of the original file against the transferred file using this command:

cmp -l tftp_file_name /tftpboot/tftp_file_name

If the data within the files to see if TFTP is working properly. If they are the same, no message will be generated.

Troubleshooting TFTP Problems

Here are some things to check if you encounter TFTP problems.

•Verify that the /tftpboot directory exists and has read, write and execute (777) permissions with this command:

ls -l /tftpboot

If necessary, use this command to create the directory:
