    <p>I would like to use rsync via ssh to copy files from <em>source-machine</em> to <em>dest-machine</em> (both Linux boxes). Due to a security policy that is beyond my control, the files on <em>dest-machine</em> must be owned by <em>user1</em> but <em>user1</em> is not allowed to log in. I am <em>user2</em> and can log in via ssh to both machines, <em>user2</em> is in the same group as <em>user1</em>, and both users exist on both machines. After logging into either machine <em>user1</em> can become <em>user2</em> by first doing <em>sudo -s</em> (no password prompt) and then <em>su user1</em>.</p> <p>The files typically have the following permissions:</p> <pre><code>source-machine: -rw-rw-r-- user2 group1 file.txt dest-machine: -rw-rw-r-- user1 group1 file.txt </code></pre> <p>Rsync always changes the ownership on <em>dest-machine</em> to be user2, becuase I am using</p> <pre><code>/usr/bin/rsync -rlvx --delete --exclude-from ignore-file.txt --rysnc-path="/usr/bin/rsync" /path/to/files/ -e ssh user2@dest-machine.example.com:/path/to/files/ </code></pre> <p>as part of the rsync command. At the moment, I have to work out which files have been copied and change the ownership back to <em>user1</em>.</p> <p>I saw in <a href="https://stackoverflow.com/questions/14351190/syncing-local-and-remote-directories-using-rsyncsshpublic-key-as-a-user-differ">this discussion</a> that it may be possible to use</p> <pre><code>--rsync-path='sudo -u user2 rsync' </code></pre> <p>but I need the intermediate step of <em>sudo -s</em>.</p> <p>Is there a way to get rsync to leave the files on <em>dest-machine</em> owned by <em>user1</em>?</p> <p>UPDATE: Thanks to mnagel's comment, I tried that permutation, and when that didn't work, I was exploring why and added two more permutations: (1) I ran the script at <em>source-machine</em> as root and (2) I had somehow not included -go as options. (I hadn;t used -a, as the security policy doesn't allow preserving times). When put altogether, it works. </p>

    1. COassuming the mentioned discussion is right: have you tried `--rsync-path='sudo sudo -u user2 rsync'?

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.
