The first step is to create the key pair on the client machine (there is a good chance that this will just be your computer):

ssh-keygen -t rsa

Copy to Server

cat ~/.ssh/id_rsa.pub | ssh root@[your.ip.address.here] "cat >> ~/.ssh/authorized_keys"

Rsync Examples

Origen: http://www.tecmint.com/rsync-local-remote-file-synchronization-commands/

1- Copy/Sync Files and Directory Locally

This following command will sync a single file on a local machine from one location to another location. Here in this example, a file name backup.tar needs to be copied or synced to /tmp/backups/ folder.

Copy Files
[root@tecmint]# rsync -zvh backup.tar /tmp/backups/

Copy Directory
[root@tecmint]# rsync -avzh /root/rpmpkgs /tmp/backups/


 2- Copy/Sync Files and Directory to or From a Server

This command will sync a directory from a local machine to a remote machine. For example: There is a folder in your local computer “rpmpkgs” which contains some RPM packages and you want that local directory’s content send to a remote server, you can use following command.

Copy a Directory from Local Server to a Remote Server
[root@tecmint]$ rsync -avz rpmpkgs/ root@192.168.0.101:/home/


Copy/Sync a Remote Directory to a Local Machine
 [root@tecmint]# rsync -avzh root@192.168.0.100:/home/tarunika/rpmpkgs /tmp/myrpms

Install Wine on Debian

Fuente: http://ask.xmodulo.com/install-wine-linux.html

Since Wine is included in the default repository of Debian, you can install it with apt-get. However, if you are using 64-bit Debian, you need to enable multi-architecture, as Wine is a 32-bit application.

On 64-bit Debian:

$ sudo dpkg --add-architecture i386
$ sudo apt-get update
$ sudo apt-get install wine-bin:i386 

 

On 32-bit Debian:

$ sudo apt-get install wine
