copied!<p>I am not familiar with JSch. But if you have root access, you can update your sudoers configuration file to get around this. Add the following line to /etc/sudoers</p> <pre><code>Defaults:USERNAME_HERE !requiretty </code></pre> <p>Maybe someone else can elaborate on whether this is a bad idea or not, that's beyond the scope of my knowledge, but I'd love to know more? </p> <p>I only use this approcah in one specific situation. We have a cronjob that backs up a cluster of remote servers via rsync, but for rsync to run successfully, it needs sudo privileges. </p> <p>To get around this I did the following-</p> <ol> <li>Created a user "backupuser" - On both servers local & remote</li> <li><p>Added the following two lines to /etc/sudoers - Only needed on the server you want to grant sudo privileges to the user on. In our case, only on the remote server.</p> <pre><code>backupuser ALL = NOPASSWD: /usr/bin/rsync DEFAULTS:backupuser !requiretty </code></pre></li> </ol> <p>Adding these two lines grants the user, 'backupuser' sudo privileges for rsync command without the need to enter a password and without the required tty connection. </p> <p>Here's how it works-</p> <p>The first line breaks down into two parts. </p> <pre><code>USER SPECIFICATION OPTION_TAG (: CONDITIONS(opt)) </code></pre> <ol> <li><p>USER SPECIFICATION - this sets the user that these options apply(s) too.</p> <pre><code>backupuser </code></pre></li> <li><p>OPTION_TAG - the tag for the option you what to grant. In this case, the user is granted sudo privileges without having the enter a password. (see <strong><em>man sudoers</em></strong> for a list of tags available)</p> <pre><code>ALL = NOPASSWD </code></pre></li> <li><p>CONDITIONS - You also have the option to place conditions on when to grant sudo privileges. In this case, the user only has sudo privileges to run the rsync command.</p> <pre><code>: /usr/bin/rsync </code></pre></li> </ol> <p>The second line, overrides the default requirement of the sudo command that you need a terminal connection to run sudo (tty requirement). And it grants this privilege only to the user account 'backupuser'. (See <strong><em>man sudoers</em></strong> for the other DEFAULTS)</p> <pre><code>DEFAULTS:backupuser !requiretty </code></pre> <p>Hope this helps answer your question. I know it went on a bit of a tangent, but I wanted to give a full explanation. For more info you can also checkout <strong><em>man sudo</em></strong></p>
