<br />
Give this a try sometime:<br />
<blockquote class="tr_bq">
<span style="font-family: 'Courier New', Courier, monospace;">icinga ALL = (ubuntu) NOPASSWD:ALL</span></blockquote>
<br />
This allows the user icinga to run anything it wants as ubuntu without asking for a password. You trigger this by having icinga trigger the command like:<br />
<blockquote class="tr_bq">
<span style="font-family: 'Courier New', Courier, monospace;">sudo -u ubuntu -i /home/ubuntu/bin/awesome_script.sh </span></blockquote>Anonymoushttp://www.blogger.com/profile/00426401885762284041noreply@blogger.com0tag:blogger.com,1999:blog-2981574586748860278.post-574022511241349822012-06-13T11:18:00.000-07:002012-06-13T11:37:56.532-07:00Image systems via rsync<br />
In case you ever need to, say, back up a system to a massive fileserver you have lying around, try this:<br />
<br />
Client:<br />
<blockquote class="tr_bq">
<span style="font-family: 'Courier New', Courier, monospace;">gzip /dev/sda | nc myserver 33333</span></blockquote>
Server:<br />
<blockquote class="tr_bq">
<span style="font-family: 'Courier New', Courier, monospace;">nc -l 33333 > foo-laptop-2012-06-image.gz</span></blockquote>Anonymoushttp://www.blogger.com/profile/00426401885762284041noreply@blogger.com0
