SNF Lab Members:
Rostam asked me how to transfer files to/from memory sticks on the
SunRays. I suspect that more than a few of you may be interested in
that answer, so I will post it here. It turns out that it is quite
simple .... but only if you know where to look for the files. In fact,
we've added some features that should mount and show the files on your
Memory Stick automatically.
First, login to the SunRay that you want to use .... before your insert
your memory stick.
Second, insert your memory stick into one of the 4 USB slots in the back
of the SunRay. This is actually the trickiest part as there are 4
closely spaced USB slots and two of them are in use with the keyboard
and mouse.
Depending on the size of the memory stick (the SunRays only have a USB
1.1 connection, I think ....) you will soon see a File Browser window
open that contains the contents of your USB device. If you have a
high-capacity memory stick, this may take a minute or two .... and the
LED on your memory stick will likely be flashing as it figures out what
is already on that device. In the top bar of the File Browser you will
also see the name of the directory in which those files are mounted.
That will be something like:
/tmp/SUNWut/mnt/${user_name}/${memory_stick_name}. In other words, if
your login name is johndoe and the name of your memory stick is
MyFlashDrive, then all of your files will be visible in the directory
/tmp/SUNWut/mnt/johndoe/MyFlashDrive. If you have not actually given
your flash drive a name, it will appear in the directory named "noname"
.... in other words /tmp/SUNWut/mnt/johndoe/noname.
You can either use the GUI-based File Browser to copy files from your
memory stick to some where in your home directory or can also copy files
from your home directory to your memory stick.
Of course, you can also open up a command window and use the Unix copy
command to copy files to/from your memory stick.
For example, to copy a file named MyFile.txt from your home directory to
your memory stick named MyFlashDrive you could issue the command:
cp ~/MyFile.txt /tmp/SUNWut/mnt/${user_name}/MyFlashDrive
where, of course, ${user_name} is replaced by your login name.
Alternatively, one way to copy a file named SomeOtherFile.txt from your
flash drive named AnotherThumbDrive to your home directory would be to
issue the command:
cp /tmp/SUNWut/mnt/${user_name}/AnotherThumbDrive/SomeOtherFile.txt ~
If you are unfamiliar with Unix, the tilde character "~" is an alias for
"my home directory". So, ~/SomeDirectory/SomeFile.txt is a way of
naming the file SomeFile.txt that is in the directory named
SomeDirectory in your home directory.
In any event, I'm hopeful that you'll find this improved access to
moving files onto or off of the SunRays with a USB.
Note: when you are done with your USB memory stick, you simply have to
remove it.
Remember, if you have a big memory stick and it is quite full, it will
take a while for this to open up on your desktop because the peak read
rate of USB 1.1 is only 12 Mb/second (which is 1.5 MB/second) using the
standard conventions of Mb = mega-bit and MB = mega-byte.
Let me know if you have any questions or problems,
John
