    <p>I've written a little script to supply a password to sshfs, but for some reason sshfs isn't grabbing the password. Any pointers? (PS I know ssh keys are better/safer, but politics where I work prevents key based authentication being setup on the target server - sigh... ).</p> <pre><code>#!/usr/bin/expect # NOT WORKING!! exp_internal 1 spawn sshfs server:/export/pc_storage /home/sonia/mnt/server expect { "assword:" { send "secret\r\r" send_user "\n" } timeout { send_user "timed out!\n" } } </code></pre> <p>To terminate the password, I've tried \r \n \r\r - none work.</p> <p>Debugging output, showing that password prompt is triggering:</p> <pre><code>spawn sshfs server:/export/pc_storage /home/sonia/mnt/server parent: waiting for sync byte parent: telling child to go ahead parent: now unsynchronized from child spawn: returns {17532} expect: does "" (spawn_id exp6) match glob pattern "assword:"? no pcuser@server's password: expect: does "pcuser@server's password: " (spawn_id exp6) match glob pattern "assword:"? yes expect: set expect_out(0,string) "assword:" expect: set expect_out(spawn_id) "exp6" expect: set expect_out(buffer) "pcuser@server's password:" send: sending "secret\r\r" to { exp6 } % uname -a Linux zapote 2.6.38-10-generic-pae #46-Ubuntu SMP Tue Jun 28 16:54:49 UTC 2011 i686 i686 i386 GNU/Linux % sshfs -V SSHFS version 2.2 FUSE library version: 2.8.4 fusermount version: 2.8.4 using FUSE kernel interface version 7.12 </code></pre> <p>SOLVED:</p> <p>(I can't post an answer as I don't have 100 points - double sigh)</p> <p>I need to fix this up a bit...

    1. COOne `\r` should be correct. Try adding `expect eof` to the end of your script and let us know what happens.

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.
