Mailinator(tm) Blog. Backup remoto de bases de datos MySQL con mysqldump | Dreaming Bytes. Las bases de datos guardan información fundamental para nuestro negocio o actividad, y un aspecto a tener muy en cuenta es realizar copias de seguridad o backups regulares tanto de los datos que contienen como de su estructura. Las webs, como aplicaciones que son, no están exentas de necesitarlas, pues ya sea por ataques o por desgracias físicas de los servidores en las que están alojadas, no podemos permitirnos dejar a nuestros usuarios o visitantes sin servicio, así que es necesario contar con una buena política de copias de seguridad.
Si tenemos una web, blog, servicio online, etc y utilizamos una base de datos MySQL podemos emplear diferentes mecanismos para realizar la copia de seguridad, por ejemplo entrar enphpMyAdmin, si disponemos de él, y hacerla manualmente. Mysqldump -h [nuestro.servidor.com_o_IP] -u [usuario] -p[password] [base_de_datos] > archivo_backup.sql Este comando nos creará el archivo archivo_backup.sql con el contenido de la base de datos que le hayamos indicado. . #!

A Recovering Physicist: How To Move A Mailman Mailing List Between Domains Or Servers. I have a VPS (virtual Private Server) running CentOS 5.4 and Plesk Web-hosting management software. Under Plesk, Mailman is installed; this mailing-list management package is not necessarily present by default in Linux distributions. I host a few dozen domains with a number of Mailman mailing lists scattered across them. Recently I had occasion to move a mailing list from one domain to another on the same server. It was not immediately clear how to go about this, and Googling didn’t turn up much that was helpful. So I’m documenting the process here in case it proves useful to others.
The technique, with suitable modifications, works as well to move a list from one Linux server to another. Caveat The file-system locations I discovered for components of the Mailman infrastructure may be dependent on Plesk. . # find / -name \*archives\* -print | grep 'private' | more Overview and tools To move a list, it must be deleted and recreated. 0. . % sudo su -l root Password: 1. 2. 3. 4. 5. 6. 7. Top 8 Tools For Linux / Unix Memory Forensics Analysis. You can dump Linux or Unix server memory. This is useful for forensics analysis, and testing your own system. This is often desirable to see: What code and what data actually resides in memory.You can search for specific pids memory.Search memory for string and other data such as passwords.Works as add-on tool for gdb and others.Search/replace/dump memory from running processes and core files.All kinds of deep hacking activities that simply saves your time and solve problems.
LiME (Linux Memory Extractor) From the project home page: LiME (formerly DMD) is a Loadable Kernel Module (LKM), which allows the acquisition of volatile memory from Linux and Linux-based devices, such as those powered by Android. => Download LiME Draugr By using /dev/(k)mem or a memory dump, Draugr can be used to access easily in python to this memory, play (read, write, disassemble, search) with it … and can find system information (processes …) by different methods. => Download draugr Volatilitux Memfetch Memgrep Memdump.
