  • Ha! Long time ago I invented a kernel mode patch for that. It was called xt_appf for 3.2.12 kernel. It was able to use it with OUTPUT table for every program and it matched by it's /proc/self/exe symlink contents. Now I don't support it and do not use it because I found a way to patch xt_owner to extend it to groups marker and match by assigning a gid to groups that process have. – user140866 Oct 31 '15 at 6:33
  • Do you mean reserve a particular port for a particular application? You want to make sure the tsm backup has exclusive access to a port? Or you wnat it to not use a port. In case you don't know, you can tell tsm which port to use on the client side. It's TCPClientPort in dsm.sys – Otheus Nov 6 '15 at 20:00
