If a user wants to execute a command, he has to first log in into a system. But some users in the system have /bin/false or /sbin/nologin set as a default shell in the /etc/password file. If I change /bin/bash to /bin/false in case of my user, I won't be able to log in into the system, so I also won't be able to run commands. But the shellless users do it anyway: How can a user without a shell execute a command? In POSIX, every running process has three User IDs (UIDs) associated with it; the real UID, which identifies the user who launched the process, the effective UID, which is used to determine what resources the process can access, and the saved Set-User-ID (SUID), which is the effective UID the process had when it started (at the point of the last exec() call). Of these, the effective UID is the most significant, since it is the one used when determining access control decisions regarding the process.

Mounting an NFS (Network File System) share using a Unix-like operating system is pretty straight forward. But how do you mount an NFS share of a UNIX system from a Windows 10 machine? Keep reading to find out how. With that said let’s install the Services for NFS feature and mount an NFS share. The first thing we need to do is install the NFS Client which can be done by following the steps below: With the default options you will only have read permissions when mounting a UNIX share using the anonymous user. We can give the anonymous user write permissions by changing the UID and GID that it uses to mount the share.

Here is the output to some inspection that I did. With that in mind, how do I go about changing the default to 1.6 so that when I execute java -version, it tells me 1.6? I am on Fedora but I hope that alternatives works the same way on Ubuntu. You need to run update-alternatives --config java (on Fedora just alternatives --config java) to see what options you have. Then type the number of the JDK you want to use and press enter.

Yes, for some reason one of my VMs was configured with a different keyboard layout. The solution is quite simple all you have to do is edit /etc/sysconfig/keyboard with your favorite editor to make the keyboard layout US friendly. I am using VI as an example you can use whatever text editor you prefer.

I am using IIS as a webserver on my development machine for PHP webdevelopment. Or at least, I am trying to. When there is a syntax error in a PHP script and I open that file in my webbrowser, I just get an 503 "internal server error" and the default IIS error page for this error. Some browsers dont open that file at all, possibly because of the 503 HTTP Response Header. I would like IIS to act in that case just like the apache webserver: display the PHP file with the error anyway, so that the error message gets printed out. How can this be done?
