That has several advantages: It doesn't solve the problem where this discussion originated, but i like this idea. I've seen programs dump 80 MB core files over ethernet -- and once they do this, you cannot stop them. (Maybe you could quickly delete the file from the server, so the client would get a stale NFS file handle, but it's a crock.) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
