Also remember that, even without a test case, we can often debug from a combination of wire trace (see http://wiki.samba.org/index.php/Capture_Packets) and dmesg output (from enabling cifs debugging e.g. The dmesg or syslog (/var/log/messages) will show certain serious errors, but enable additional cifs debugging flags to increase the debug output. You can do this by doing: #dmesg -c /* this clears kernel ring buffer */ #echo 3 > /proc/fs/cifs/cifsFYI /* Enables additional debugging */ <do the operation> #dmesg > cifs-debug.txt Attach cifs-debug.txt On Tue, Nov 1, 2011 at 1:04 PM, Nick Davis <nick@xxxxxxxxxxxxxx> wrote: > Thanks for the reply, Jeff.
