[gPXE] how to set TFTP blksize

[Sean Lv]

Hello Doug

Thanks. Are you sure? We didn't find the setting about UDP buffer size on
TFTP server. I am using Win SRV 2008.

I checked the TFTP packets from client to server. The blksize information is
encapsulated in the UDP packets.  There is another evidence. When gPXE was
loaded then fetch any image or boot loader, the TFTP blksize=1432(always).
When I load other kind of boot loader from native PXE(built-in NIC), the
TFTP blksize=1456.  I am not sure if you know GRUB4DOS. It's a boot loader.
I can set blksize with CLI: pxe blksize value.  So I think the blksize
should be set on client side. Agree? But how to do it in gPXE?





 
 
 
Thanks
 
Best Regards

You would need to increase the UDP on the TFTP server, there isn't a
GPXE command to do this.
