Remote Desktop on Debian Using X2Go
This article will guide you on the steps to set up remote desktop on #Debian. X2Go can be used to access Windows systems through a #proxy. Client packages can be run on #FreeBSD, Linux, #OS X, or #Windows.
With the desktop sharing function of X2go you can gain full-access to the desktop of another computer, similar to programs such as Remote Desktop, TeamViewer, and LogMeIn. You can see an #X2go session from somebody else, but you can also see a normal desktop. Desktop Sharing functionality requires access to port 22.

2. Input the #Linux computer's network name, or enter the IP address you noted earlier.
3. Select SSH, then Open.
4. When prompted to accept the certificate for the connection, do so.

Copy rds snapshot to s3
This article will guide you on resolve common rds #error. Basically, the process to copy rds snapshot to s3 is simple and creates and saves backups of the DB instance in the Amazon S3 bucket.
Amazon Relational Database Service (#Amazon RDS) makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while automating time-consuming administration tasks such as hardware provisioning, database setup, patching and backups.
RDS creates a storage volume snapshot of your #DB instance, backing up the entire DB instance and not just individual databases. RDS saves the automated backups of your DB instance according to the backup retention period that you specify.
To copy a #RDS snapshot from one region to another:
1. Create a #snapshot of your RDS.
2. In your newly created snapshot go to Actions -> Copy Snapshot.
3. Click orange View snapshots in destination region.
4. In the target region's snapshots table find your copied snapshot, and wait until status "Copying" becomes "Completed".
5. Select the snapshot, click Actions -> Restore Snapshot.
Preserve Permissions in rsync
This article will guide you on how to use rsync to preserve permissions.
Rsync, or Remote #Sync, is a free command-line tool that lets you transfer files and directories to local and remote destinations. #Rsync is used for mirroring, performing backups, or migrating data to other servers.
a = archive - means it preserves #permissions (owners, groups), times, symbolic links, and devices. Use of "/" at the end of path: When using "/" at the end of source, rsync will copy the content of the last folder.
To preserve permissions when files and folders are copied or moved, use the Xcopy.exe utility with the /O or the /X switch.
The object's original permissions will be added to inheritable permissions in the new location.
To make rsync to preserve timestamps:
1. To overcome this, there is another option that you can specify in the rsync command that will preserve the timestamps during the synchronization process.
2. Without preserving the timestamp, the files will display the modification date and time as the time that the rsync command was run.
OpenVPN on Linux
This article will guide you on steps to set up OpenVPN on Linux.
OpenVPN config files (. ovpn) offer an easy way to configure #OpenVPN on your computer to work with our servers. These files contain the correct cipher types, #Certificate Authority, Certificate, and Private Keys. You can use these files on Mac, Linux, #Windows, Android, and iOS.
By default the OpenVPN Access Server comes configured with OpenVPN daemons that listen on port 1194 UDP, and OpenVPN daemons that listen on port 443 TCP. While the best connection for an OpenVPN #tunnel is via the #UDP port, we implement TCP 443 as a fallback method.
To Set up OpenVPN Server on Ubuntu #Linux:
1. Find and note down your public IP address.
2. Download openvpn-install.sh script.
3. Run openvpn-install.sh to install OpenVPN server.
4. Connect an OpenVPN server using iOS/Android/Linux/Windows client.
5. Verify your connectivity.

WordPress Brute Force Attack
This article will guide you on Brute Force Attack and different ways to troubleshoot and fix a Brute-Force Attack in #WordPress.
Brute-force attacks work by calculating every possible combination that could make up a password and testing it to see if it is the correct password.
As the password's length increases, the amount of time, the computational power required on average, to find the correct password increases exponentially.
#Brute #Force #Attack Prevention Techniques:
1. Limit failed login attempts.
2. Make the root user inaccessible via #SSH by editing the sshd_config file.
3. Don't use a default port, edit the port line in your sshd_configfile.
4. Use Captcha.
5. Limit logins to a specified IP address or range.
6. Two factor authentication.
7. Unique login URLs.
