LINUX TRAINING COURSE DESCRIPTION
A Linux foundation appropriate for all flavours of Linux, focussed on getting
network engineers up and running with Linux. The command line is used
throughout. The course progresses from the basics of Linux commands onto useful
tools such as grep, then shell features such as piping and then onto shell
scripting. Administration aspects covered are the tasks network engineers are
most likely to encounter such as software installation. Hands on exercises
concentrate on network related tasks such as installing net-snmp and using shell
scripts to provide network automation.
