Hi all,
[Please CC me in reply, I'm not subscribed]
We have a weird situation on one of our shares, net rpc share
allowedusers fails with NT_STATUS_IO_DEVICE_ERROR. Normally the command
is run with the password passed on the command-line. If we manually type
the password or turn up the debug level, it works. If we turn up the
debug output but direct the output to /dev/null or to a file, then it
works. If we run net under valgrind (slowing it down) then it works
about half the time. So there is some sort of race condition going on I
think. Does anyone have any thoughts about fixing this on the server
side or working around it client side (Ubuntu precise)?
This is the samba client version:
Ubuntu precise-updates 2:3.6.3-2ubuntu2.4
This is the server version string:
Domain=[XXX] OS=[Windows 7 Professional 7601 Service Pack 1] Server=[Windows 7
Professional 6.1]
This is the failing call and error output:
cli_rpc_pipe_open_noauth: opened pipe \srvsvc to machine cvision-pc and bound
