I found what is happening
If I use a non absolute path it works: the remote config should be on

same directory with fio
Nossa Senhora:fio.patch neto$ ./fio --client 10.61.109.151
--remote-config
conf3
If I specify an absolute path, it does not work
Nossa Senhora:fio.patch neto$ ./fio --client 10.61.109.151
--remote-config

Do you think we could fix it to make sure we can use --remote-config
with
an absolute path?
That's very odd, there should be nothing special about it. If I do this:
axboe@lenny:/home/axboe/git/fio $ stat /root/x.fio
stat: cannot stat Œ/root/x.fio¹: Permission denied
$ ./fio --client=localhost --remote-config /root/x.fio
and run
axboe@lenny:/home/axboe/git/fio $ sudo strace -o x -f ./fio --server
fio: server listening on 0.0.0.0,8765
and then look at the x strace output file, it all looks fine:
28632 recvfrom(4, "\v\0\1\0/root/x.fio", 15, MSG_WAITALL, NULL, NULL) =
15
28632 open("/root/x.fio", O_RDONLY) = 5
which is all find and dandy. Fio just passes the string of the filename,
and the server just does an fopen on that passed in file. So please run
the same experiment on your end with an strace of the server and the
arguments you used on the client, I'd like to see that.

Hi Jens,
This is neto from Brazil
How are you?
It's very strange....
I have applied the patch again... Make clean, make and it's working now :-(
On linux it's working
But I applied the patch on my mac, but it's not working
Nossa Senhora:fiop neto$ patch < net-remote-config.patch

Could you please make the changes to github and I will download form
there. Something is not right here with the patch.
Always ensure that you make clean, might be the same on the mac. In any
case, it's committed, but it a separate branch. So when pulling, you
need to checkout the remote-config branch. Once it's fully done, I will
pull it into the master branch.
