4. Now I already have BDI-new.cfg file in my /tftpboot/

PC. I pinged BDI. Response is OK. Then I made 'telnet' to BDI. The following is the brief response.

Means, it is not getting my BDI-new.cfg file even though

the file is in

/tftpboot/ directory on my PC while my PC is working as

TFTP server. Why

...

it is BDI is not able to read BDI-new.cfg ?

Try:

chmod a+r /tftpboot/BDI-new.cfg

That should fix it assuming tftp is properly configured and enabled on your RH8 development host.

Other potential problem areas and checks: * Can you use tftp to read your BDI-new.cfg file from the tftp server (i.e. tftp localhost)? If so, you have your server basically functioning. Good.

* Can you use tftp to read it from _another_ machine? If not, you have a permissions problem likely relating to firewalling (TFTP not allowed to the ethernet).

* Depending on your tftp server setup, you may need /tftpboot/BDI-new.cfg or /BDI-new.cfg (the later configuration is strongly recommended).
