    <p>Me and my colleague have a project, to make a driver which will provide access to a remote drive like it was a local drive (using SSH/SCP). The drive should be seen normally as a drive, and operations can be limited to simple file operations (copy, move, remove), without file listing etc. The driver should be a linux kernel module (maybe not entirely..).</p> <p>We managed to gather some informations and ideas, and maybe someone could verify them, or push us to a good direction?</p> <p>We thought about splitting it into 2 components:</p> <ul> <li>a kernel module implementing a virtual drive,</li> <li>a user-space daemon responsible for SSH/SCP communication,</li> </ul> <p>because we can't imagine implementing SSH communication in a kernel module (YES it probably is POSSIBLE, but..).</p> <p>For SSH/SCP communication we think we can use <a href="http://www.libssh.org" rel="nofollow">libssh</a>. About implementing virtual drives in kernel module we found a <a href="http://lwn.net/Articles/57369/" rel="nofollow">tutorial</a>.</p> <p>Another case is communication between kernel and user-space. We also found an <a href="http://people.ee.ethz.ch/~arkeller/linux/kernel_user_space_howto.html" rel="nofollow">article</a> discussing this, with many possibilities like UDP sockets or NETLINK.</p> <p>With this solution, we could forget about any SSH/SCP related stuff in kernel module - it will be transparent to the kernel.</p> <p>Is our thinking good? Maybe there are some caveats we didn't forseen? Is this the right way, or maybe there is a better/simpler method (but still related to the linux kernel, because that's the main field of the project ;)) ? Which ideas we should use? Links much appreciated :)</p> <p><strong>EDIT</strong>: It's a project we have to do for an university class - so it's not the problem to find an already implemented solution, but to do your own..</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
