Unhappy TFTP help!!!


Hi,

I am trying to install Redhat 6.2 for my UltraSparc 1 through internet. I set up one Ultra1 as server to supply ARP/RARP service and TFTP service by following the instruction " how to net boot Linux". And I also checked the working status of my TFTP server from the other computer under the same private network by trying to get the file tftp64.img which is under /tftpboot directory. There is no problem to get it. Now when I try to boot the client with the command "boot net". And I also open the "tcpdump" in my server to monitor it. The client has no problem to get its IP address from the server, 10.0.0.3 in my case. But when it tried to get the tftp64.img to boot, it failed. And the error message is "Framing error CRC error". Does anyone know how come that error happens?

Thanks in advance.

I've just recently done the same thing to install RH6.2 on my Sparc 10 and had no troubles of this kind, once i got tftp going it was fine. If the tftp server works fine from another host then I would suspect the cabling or the network card in the UltraSparc1 client box. If i'm not mistaken CRC and framing errors can be a result of bad hardware. I'd check cable and the NIC in the UltraSparc1. Good Luck!

UDP is not a reliable and connexion based protocol. That's why it doesn't "LISTEN". It "listen", but not in the way that TCP "listen".
