GNU/LinuxHow to add a user to an existing group ?

$ adduser -g group -d /home/group/user user

How to create a block device from a file ?

For a 100M size file:

$ dd if=/dev/zero of=/root/block1 bs=100M count=1
$ losetup /dev/loop0 /root/block1
$ mkfs -j /dev/loop0
$ mount -t ext3 /dev/loop0 /mnt/newfs

How do I do an automatic backup ?

#!/bin/bash

cd /over/the/repository/to/backup
date +%d-%m-%Y > date
tar -zcvf /repository/for/backup/`head date`.tgz /repository/to/backup
rm date

How do I do an automatic dump ?

For PostgreSQL database :

#!/bin/bash

cd /repository/for/dumpfile
date +%d-%m-%Y > date
pg_dump -D database -U username > `head date`.database.sql
rm date

The password will be asked at the prompt, which is a problem I have never solved yet.

For MySQL database :

#!/bin/bash

cd /repository/for/dumpfile
date +%d-%md%Y > date
mysqldump -D database -u username -p passwd > `head date`.database.sql
rm date

You can copy these lines in a file, and move it to /etc/cron.daily/, for example.

Savoir-faire Linux

Max @ 20:37 | Filed under: Information Technology

Savoir-faire LinuxI had carried out my internship from May to October 2004 in Savoir-faire Linux Inc, Linux integrator in Montreal.

Project : LABE – LDAP Address Book Editor

Savoir-faire Linux Inc has been at the origin of the LABE Project (LDAP Address Book Editor) and I learnt a great deal participating to the development of this open-source project.

On May the 20th, I released the 3.3 version of LABE.

Project : Network Monitoring

Savoir-faire Linux Inc is responsible for hosting many websites and wants to know the bandwidth used by each one in a month. After studying SNMP, Ntop and Iptables, I have found a complete NetFlow solution using Fprobe and Flavio. You can download the report of my internship: [PDF] and the slides of my presentation : [PDF].
