...gs with this output: debug1: channel 0: read<=0 rfd 11 len 0 debug1: channel 0: read failed debug1: channel 0: close_read debug1: channel 0: input open -> drain debug1: channel 0: ibuf empty debug1: channel 0: send eof debug1: channel 0: input drain -> closed Could it be related to "NON_BLOCKING"of fd=11? Or to "TCP_NODELAY" of fd=4? I seem to be the only one having such problems, thus it might be a config/compilation issue. CAn anyone at least verify what evil thing this program does? telnet/rlogin/ssh-on-linux pass the sshd-test-program below. I used openssh3.5p1 with...

Hi Steven, The following patch set provides a feature which can read trace data of a guest using virtio-trace (https://lkml.org/lkml/2012/8/9/210) for a recorder function of trace-cmd. This patch set depends on the trace-agent running on a guest in the virtio-trace system. To translate raw data of a guest to text data on a host, information of debugfs in the guest is also needed on the host. In
