Appendix B: Image File Download Using OID Strings

B.1 SETTING UNIX WORKSTATION AS TFTP SERVER

Downloading an image file requires setting up your UNIX workstation as a TFTP server.

NOTE

Due to variations between UNIX systems, and individual configurations, this section provides only GUIDELINES for configuring a UNIX workstation to perform an image file download. The instructions include command examples, where appropriate. Bold lettering in examples indicates operator entry.

If unsure about how to properly configure your UNIX

!workstation using these guidelines, contact your Systems CAUTION Administrator.

Use the following steps to set up a UNIX workstation:

1.If you already have a /tftpboot directory, confirm the TFTP setup of your workstation as follows:

Request a process status and grep for TFTP (e.g., unix% netstat -a grep tftp).

The following information represents a typical output:

user

12:00

grep tftp

root

?

S

11:05

tftp -s

The term tftp -s, located at the end of the root string, indicates TFTP is active. If TFTP is NOT running, only the grep process appears.

2.If you do NOT have a /tftpboot directory, then create one (e.g., unix% mkdir tftpboot).

3.Ensure that the /tftpboot directory is not owned (e.g., unix% chown nobody tftpboot).
