Re: tftp boot server on Redhat linux 9

Hi All,

Thanks a lot for you segestions.

I edited the configuration file '/etc/xinetd.d/tftp'

& now it has:

service tftp
{
	socket_type		= dgram
	protocol		= udp
	wait			= yes
	user			= root
	server			= /usr/sbin/in.tftpd
	server_args		= -u nobody -s /tftpboot
	disable			= no
	per_source		= 11
	cps			= 100 2
	flags			= IPv4
}

after that I issued the following command to restart the tftp server:

$ /etc/rc.d/init.d/xinetd restart

Then from my tftp client (target board running YAMON) issued the command to 
get a file using tftp:

YAMON> load tftp://4.42.102.5/vmlinux.rec
About to load tftp://4.42.102.5/vmlinux.rec
Press Ctrl-C to break
Error : TFTP READ-REQ timeout ERROR
Hint  : Check TFTP-server is up and running

where:
vmlinux.rec is in /tftpboot on the PC host
4.42.102.5 is the IP of my host PC running Redhat Linux 9
4.42.102.6 is the IP of Target board running YAMON (TFTP client)


Connection:

Target running YAMON <--> hub port - Ethernet HUB - hub port <--> PC running 
RH Linux 9

These are the only 2 machines physically connected in the network.

Ping works from either side.

Questions:
1. Is the network set-up OK for tftp (its a peer-to-peer connection)?
2. The TFTP status using 'redhat-config-services' shows xinetd. Is this too 
advanced for the YAMON - Compatibility issue?
3. Do I need to reboot RH Linux for the configuration to take effect?
4. Do you find anything missing or wrong.

Please advice me why I am not able to do tftp downloads.

Thanks,
-Mike.
