COURSE OBJECTIVE:
Course Objectives On completion of this course the delegate will have the required technical knowledge to administer a SUSE Linux server within the Enterprise. They will have gained practical experience of configuring administrative,networking,performance and security aspects of a SUSE Linux Enterprise system (SLES).
TARGET AUDIENCE:
Who will the Course Benefit? The SUSE Linux System Administration (SCA) training course is suitable for novice Linux System Administrators,Programmers and other technical IT staff who need to acquire administration knowledge of the key administrative,networking,performance and security tasks required on a SUSE Linux operating system within the Enterprise. An ideal course for delegates who will be working in an environment using several different Linux distributions and therefore knowledge of skills common to all the different Linux distributions is required. For the purpose of practical exercises,SUSE Linux will be used. Note: Should the delegate only require knowledge of Red Hat Linux then they should instead consider attending our range of Red Hat Linux Administration courses.
COURSE PREREQUISITES:
Requirements This SUSE Linux System Administration (SCA) course assumes good knowledge of the Linux operating system in an Enterprise environment to the level covered in the Linux Introduction course. Alternatively,relevant experience of UNIX or Linux servers is required,preferably within an enterprise environment. Knowledge of Linux Shell Programming to the level covered on the Linux Shell Programming course would also be beneficial.
