It might be your router, but it might be your ISP: I have seen ISPs blocking all DNS (UDP 53) requests to other IPs than their DNSes - they do this to either monetize (make their DNS resolve ad-sites worng on purpose) or sometimes for legal reasons (DNS-based blocking of sites). And before you ask: Yes, they deliberately break DNS.

I just deployed an Ubuntu 15.04 image, and after apt-get update, installing SELinux I was too unable to set that boolean as it is "Invalid". getsebool -a | grep http shows that there are no policies including http, and this is despite having policycoreutils installed and updated. I am understanding that this either has been removed from the Ubuntu ...

Your script starts with: #!/bin/sh This is not a comment, but a shebang to tell your operating system to use /bin/sh to execute the script. But apparently Ubuntu cannot find it. If ls /bin/sh shows no result, then I guess that needs to be fixed. As a temporary solution, you might be lucky that your script also works with, for example, bash: ...

You just have to install it as usual. You can create a bootable USB stick by using this tool. After everything is ready, restart(or turn off fast startup) your computer.

Do you have the both things installed? (Ubuntu and Windows 10)? If you do, you must have the younger OS installed first so, if you are using Ubuntu 14.04/.10 you have to install Windows 10 after it.

xterm stores saved-lines in memory, allocates those at startup (or if the window is resized, since the width can vary). The feature was rewritten starting in 2009 with patch #244 to make it more efficient than the original (which was noticeably slow at much lower than 10 million lines). konsole has a dialog allowing "unlimited" lines, which stores the ...

Ports are opened as soon as there is an application listening to them. For instance, if you install openssh-server, then port 25 TCP is open. If you then go into the configuration file and change the port from 25 to 48 and restart the server, 48 will be open and 25 closed. So, basically, whenever an application is listening, the port will be open. What ...

The problem is that your redis server is only listening on the localhost interface. Therefore it can be only acessed from its own host. Let it listen to all network interfaces by using 0.0.0.0. See the second answer here for details: http://stackoverflow.com/questions/8537254/redis-connect-to-remote-server

Parallels can use a Boot Camp Windows install as a virtual OS inside OS X - so long as you shut it down rather than suspend, when you've finished; otherwise it won't boot from Boot Camp next time.

even though ps is the process , grep is the process shown Both ps and grep are processes. You just don't see the ps line because it does not have "hello" in it. Try, for example, ps | grep ".*" instead, or even ps | sort | tac | shuf. In other words, you have: Process 1: ps aux Fd 0 (stdin): terminal (/dev/tty) Fd 1 (stdout): anonymous pipe ...
