So this is the same bof file which sometimes works and sometimes does not ? Or is this subsequent to some upgrade of the roach ? If it is a sometimes work/not work issue maybe you are not marking it executable (chmod +x) on transfer or the transfer is garbled. If it is subsequent to an upgrade: Note that at some point we moved to a different kernel+driver+tcpborphserver combination, which uses a mmap interface - if you change to that you will have to update both kernel and tcpborphserver, but for roach1 this is a backport, so probably something for experts ... regards marc
