You should then be able to set a root password using "passwd root", but I would advise against doing this on any machine that is somehow accessible by others. I can't remember what the root users default home directory is, but it's probably / or /root in ubuntu, you can change it in /etc/passwd [<a moz-do-not-send="true" href="http://www.cyberciti.biz/faq/understanding-etcpasswd-file-format/">http://www.cyberciti.biz/faq/understanding-etcpasswd-file-format/</a>]. <a moz-do-not-send="true" href="https://help.ubuntu.com/community/Java">https://help.ubuntu.com/community/Java</a> has instructions for installing Sun Java that seem rather straightforward. <div class="gmail_quote">On 9 September 2012 08:40, Nico Michael(iBurst) <<a moz-do-not-send="true" href="mailto:nick.michael@ptaisp.co.za" target="_blank">nick.michael@ptaisp.co.za</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div bgcolor="#FFFFFF" text="#000000"> Hi there I need to work as root user I need to enable the root user and set the root user password in my Ubuntu workstation in a VM I could do sudu su but I need to login with full root as the root user This is in a VM and risks mitigated Regarding risks this is a VM so I will make an image in the VMware server to recover from damage. How do I set root password I know is solaris you would use a passwd command to set the root user's password What is root home directory I also know in solaris the root users home directory in not /home/root what is it in Ubuntu Linux? The root or sudo user cant see programs pathed for non-root users how do I fix that Also I have seen certain program ran when you logged in as non-root user which did not get pathed and did not run on a Centos Server when you logged in as root I need to run Sun Java not the non-industry non-standard Java Ubuntu provides One of the problems all professional Java developers have with Ubuntu is we need to use the Industry standard so our programs work Ubuntu tends to install its own "Non-Industry non-standard" Java Which we always have to remove and then it becommes a mission to get Sun java to work To get Sun Java running on Ubuntu I remove the "Ubuntu supplied non-standard Java" then I edit /etc/profile and add JAVA_HOME="/usr/lib/jvm/java-6-sun-1.0.0.30 and then export JAVA_HOME Java does not run as the sudo or root user This works when I run java -version I get the right version of Java how ever when I run sudo java -version It cant find Java which file and or older do you put path information so the Root or SUDO user can find the Java ?
