How does one become root?

location: ubuntuforums.com - date: March 25, 2010
I made a mistake with an application I installed so uninstalled that application, did a fresh installation hoping it would be a clean application but that mistake still persist. That application sits inside file system/usr/lib so thought if I were root I could manually delete that application folder, however I can't since I'm not root. Any advise?

How does one use DHCP to get the same IP address assigned every time on openSUSE

location: linuxquestions.com - date: May 7, 2009
I have a cable-modem / router that allows me to reserve an IP address for a particular MAC address - I have used this method to assign a "static-like" IP address to all my webCAMS, Windows boxes etc even though these devices themselves use DHCP to get IP addresses assigned from the router. I can'r seem to be able to do this with my openSUSE linux box. If I use Yast and configure my system for Static IP the router doesn't even know the machine exists. If I reserve an IP address (192.168.0.203) based on the MAC address of the Linux box and use DHCP, the router thinks it has assigned the correct IP address (192.168.0.203) to the Linux box but when I run ifconfig on the linux box it shows a completely different IP address (192.168.0.177)! I need my Linux Box to get the same IP address assigned so that I can use SAMBA, VNC Viewer etc from my windows machine - How can I achieve this ? thanks much.

Hello, I am thinking of doing a raid 5 on an ubuntu server 14.04 system with 3 x 3TB drives and have a few questions... 1. How would the system boot if one of the drives goes down? 2.

How to clear terminal after SSH login?

location: linuxexchange.com - date: March 5, 2015
I am trying to connect to a server via ssh. Once connected, terminal should be cleared. Due to generated keys, I can connect to the server via ssh [email protected] without being prompted a password. This works. In order to get rid off The programs included with the Debian GNU/Linux system are free software; the exact distribution terms for each program are described in the individual files in /usr/share/doc/*/copyright. Debian GNU/Linux comes with ABSOLUTELY NO WARRANTY, to the extent permitted by applicable law. I would usually just type clear. However, I would prefer not to type this every time but automate the procedure instead. ssh [email protected] "clear" --> "TERM environment variable not set.". I googled several solutions about unset environment variables, but without success. So instead, I tried ssh -t [email protected] "clear"; this successfully clears the terminal, but also closes the connection right away ("Connection to IP closed."). Computer connects to server, clears the screen

How does linux decide which pages of a file to cache?

location: linuxexchange.com - date: June 12, 2015
Lets say I am reading random parts of multiple big files (~500MB), But I always read the same pages for the first 3 files (other files are read randomly). Does linux keep the most read pages ("hottest") in the ram constantly, or does it use a type of "random" algorithm to choose which pages to cache and which to free?
