Hi,

I think this is a development problem. I have tried everything obvious to get TFTP to work on F14 but to no avail. Could some one in the know look in to this please.

I have tftp -server working on F14 and have done PXE Instillations using it. Since then I have done a yum update and ever since then have not been able to get it to work.

Well you can run yum downgrade on the updates that you performed to nail down the one that potentially broke it.



Below in the two posts are what I have tried, as far as I can see it is exhaustive.

Many thanks in advance,

Well posts or not here is a quick debugging guide for tftp which should tell you what's going on and note that using ip-aliase are broken in tftp as it seem to be in (x)inetd based services in general...

Run

#tcpdump port 69 -v

#touch /var/lib/tftpboot/my-test-file.txt
#chmod 777 /var/lib/tftpboot/my-test-file.txt

#tftp $IP
tftp> status
tftp> trace
tftp> verbose
tftp> put my-test-file.txt ( or get my-test-file.txt )
tftp> quit


tftp> get my-test-file.txt

tftp> put my-test-file-put.txt
