comment Domain Name problems in CentOS hosted under VirtualBox
Assuming that the machine has an IP address and a gateway to the Internet, then cat /etc/resolv.conf to see which name servers have been defined. en.wikipedia.org/wiki/Resolv.conf

comment iptables rules not reloading on CentOS 6.x
@rjt The /etc/sysconfig/ipsets file stores the sets (made with a text editor or with help from the ipset command), and the sets are referenced from the /etc/sysconfig/iptables file. In the link, the author is using them correctly: blog.laimbock.com/2013/09/22/….

comment Mounting NTFS Drives in Linux Mint
@David Open a command prompt and type "chkdsk c: /f /r" to perform a full scan, including bad sectors; chkdsk will try to fix any errors. Windows will probably tell you that it will schedule the disk check for the next boot. So, then reboot and let it scan.

comment #!/bin/bash - no such file or directory
There was heated debate at one point years ago on askubuntu.com about that. It was settled that it was the BASH script writer's responsibility to use the environment; but, this also means that in a very secure environment, you risk not knowing which BASH will be used - the system version or a malware version.
