[gfarm-discuss:09380] Re: question about gfrun

[Osamu Tatebe <tatebe@xxxxxxxxxxxxxxxx>]

Hi Yikuo,

When you would like to access Gfarm file system by existing
applications, you need to use GfarmFS-FUSE or syscall hook
library.  See 

http://datafarm.apgrid.org/software/gfarmfs-fuse.en.html
http://datafarm.apgrid.org/software/syscall-hook.en.html

Regarding the problem B, it seems authentication to gfmd fails.
Would you make sure your shared secret key or gsi setting on the
host where gfmd runs?

Thanks,
Osamu
