the relevant line in /etc/inetd.conf is: 2000 nobody /usr/sbin/tcpd /usr/sbin/nbdrootd /opt/ltsp/images/amd64.img just googled what nndrootd does, and i guess mythtv installed it? or it's used by it. if i open the address host:2000 in a browser on a remote machine, i get an exe.part file, if i do it localy, iget a bin.part file, i ran strings on the files hoping to find something useful, all it had was NBDMAGIC, why is inetd and ltsp returning these files? is this normal behaviour? -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.org/UKTeam/
