A Jump Host is a special purpose computer on a network typically used to manage devices in a separate DMZ. So, I'm looking for the proper way to implement this for a target running on Windows.
I was thinking about using a tunnel to a Cygwin SSHD on the target host via some SSH client like Putty.
What is the best practice for that? Does Microsoft provide a solution?
Devel packages usually contain the headers or other stuff that's necessary for compiling applications.
To keep the systems clean and manageable, I'm looking for a command to
list all-devel-packages installed by yum (also rpm's, without the suffix).
I usually use yum list installed and collect the devel's manually.
Do you recommend to remove them after compilation as a general rule?
I've found this error in my logs:
relocation error: /usr/lib64/libmyodbc5.so: symbol strmov, version libmysqlclient_16 not defined in file libmysqlclient_r.so.16 with link time reference
yum-error-log
yum install mysqlclient16
...

Setting up Install Process
Package mysqlclient16 is obsoleted by mysql-libs, trying to install mysql-libs-5.1.59-1.el6.art.x86_64 instead
Package matching mysql-libs-5.1.59-1.el6.art.x86_64 already installed.
Checking for update.
Nothing to do
i've used the atomicrepo using the latest mysql-version (mysql-5.1.59-1.el6.art.x86_64) on a server driven by CentOS6.

Some fool in my company has scrapped the page with the root password for our hyper-v server.
Fortunately I've saved the password in the Remote Desktop Connection, so I'm able to connect remotely. How can we restore the password without forcing a reboot?
I got this strange error today and I'm not able to fix it:

How can I fix this issue ?
When updating with yum i recieve the following message:
yum update

What does that mean ? How to install these packages ?
