Is it possbile to execute linux commands with java? I am trying to create a web servlet to allow ftp users to change their passwords without ssh login access. I would like to execute the next commands:
# adduser -s /sbin/nologin clientA -d /home/mainclient/clientA # passwd clientA # cd /home/mainclient; chgrp -R mainclient clientA # cd /home/mainclient/clientA; chmod 770 .
Check out this.
However, doing what you are talking about is way outside spec, and I wouldnt reccommend it. To get it to work you are going to either run your app server as root, or use some other mechanism to give the user the app server is running as permission to execute these privileged commands. One small screw-up somewhere and you are ‘owned’.
