2629.0. "BOOTP/TFTP from a PC" by JGODCL::LBERG (gaia is moving) Thu Aug 10 1995 06:46

    Hello experts,
    
    Who tried before...
    I've the DECROU software installed on a HINOTE. I tried to reload 
    braindeath hub modules using this BOOTP/TFTP by just editting the 
    bootp.tab. After solving the file protection problem (put the image in the
    DECROU\COMMON directory), I got an Acknoledge problem. The PC receives a 
    bootp, it will start the TFTP but then it times-out after sending the first
    block. It is waiting for an ACK.
    
    Any idea for a workaround or another solution to reload braindeath
    modules firmware with a PC?

2629.1	Use the HUBloader	NETCAD::FORINO		`Thu Aug 10 1995 09:35`	12
	Use the HUBloader utility - if you have HUBwatch 4.0 you already have it. If you want it as a standalone utility see note 2110.16. My guess is you are trying to load repeaters. I seem to remember some problem with loading repeaters in that they ask for the first block twice - the first for verification and the second for the start of the actual load. So when it sends the request for the first block the second time the TFTP server is trying to send the second block and you hit the timeout. The TFTP server provided with the HUBloader has the timeout adjusted to accommodate the repeaters. John
2629.2	tried hubload also!	JGODCL::LBERG	gaia is moving	`Thu Aug 10 1995 10:57`	7
	I tried the HUloader utility but didn't manage to send the correct file after the bootp request. Request will be received, but what next. I assigned the as server the repeaters hardware address and an IP number (in the same net and subnet). What should I mention in the "Files" window?! lodewijk
2629.3	Some questions	NETCAD::FORINO		`Thu Aug 10 1995 14:27`	9
	HUBloader requires that the modules are up and running and can process SNMP requests. If your "brain dead" module can't do this then the HUBloader will not work for you. Is this the case? If not, you should get the file name by default if the device is included as part of the DEChub Firmware Consolidated kit. If not part of the kit you can put the file name in by hand (including the full path name) along with the other required info (see the online help).
2629.4	BOOTP/TFTP from a PC	JGODCL::LBERG	gaia is moving	`Fri Aug 11 1995 03:48`	9
	The only thing a "brain-death" module will do is, send out a bootp request and then just waiting for some node on the net that will supply the module an IP address, and load-file as I understand. This means that HUBload can't bring the module up again. Other suggestions for a BOOTP/TFTP possibility from a PC to load "brain-death" hub modules? Lodewijk
2629.5		NETCAD::DOODY	Michael Doody	`Fri Aug 11 1995 10:21`	4
	But I thought a TFTP server was bundled with Hubloader. Couldn't the TFTP server be used for this purpose? (I have not tried it myself). -Mike
2629.6	A definitive answer please?	MXOC00::CSILVA		`Mon Aug 14 1995 23:00`	14
	Notes 2353 2533 are about pretty much the same thing with other modules or the 900MAM, but the answer is incomplete. In other notes there are recommendations for looking at the NetRider conference that doesn't help much. Today I have a "brain-dead" 900EF and i have not been able to do the BOOTP/TFTP from HubLoader. Does anyone have a complete reference to do that? I think the problem is that there's not enough info about the options for the config files of the TFTP server.
