In verbose mode the client may show this: #verbose client Authenticated to 172.16.17.2 ([172.16.17.2]:22). debug........

Virtualbox is a very powerful tool, but for some use cases it is less than optimal. Say you are in a work, lab or other environment where you are not alone on the physical network and there could be overlap of IPs, but you need all of your VMs to be contactable from your host, VMs need to communicate with each other, and VMs need internet. NAT Network will give you VM to VM communication and internet, however, it is buggy and unstable. It also doesn't allow host to VM co........

We've all done this at some point, you work on the wrong shell window and this was my first time making this mistake but I deleted a partition table in fdisk, recreated it and saved it with "wq" and even ran partprobe! If you haven't rebooted yet then you can still recover your partition table, otherwise you're in big trouble. Fortunately since it was a live system and in use the kernel still had to use the old table like below:........

Cannot load certificate file keys/server.crt: error:0906D06C:PEM The .crt is blank empty because when generating it I kept hitting enter for the defaults and this caused the crt not to be signed.

I backed up everything in the /mnt/sd_card directory thinking that some dataloss could occur for some reason but purposely left my microSDHC unbacked up thinking that "it won't touch that since it's external" and Samsung's and other manufacturers website even say this (that it won't be affected and not to worry etc). Apparently I was wrong, my microSD was "undetected" and asked to be formatted after the upgrade (there goes 3-months worth of family photos). No........

I thought I was being smart, I wanted to download some Debian packages so I went to /var/cache/apt/archives and did "rm -rf *" but then I couldn't use apt-get anymore. I kept getting this error: E: Archive directory /var/cache/apt/archives/partial is missing. E: The list of sources could not be read. The solution was to recreate the "partial" directory inside /var/cache/apt/archives and then everything will be fine.........

Create Table with structure of another existing tableOk, this has many valid uses such as if you need to create backups or the ability to undo changes, you would want to create new tables with the same structure as another. Here is how you do it.
