Hi Nimish. I think you do need to use FTP or scp, or some such, to copy the bof to the roach's file system into the /boffiles directory. In fact we use an NFS mounted file system, but we copy our bof into the /boffiles directory on the roach file system on the host side. Then, katcp knows to look in that directory, I think, for the bof files.
