Linux for Engineering and IT Applications Course
Here is a great Linux Course from Rutgers University,
named Linux
for Engineering and IT Applications. All lectures
and content, including test answers and the text book are available
online for free. The course
topics include: Linux concepts (kernel, shells,
users, groups, processes, etc), installation and configuration
(disk partitions, GRUB and LILO boot managers, Debian Package Manager,
APT), networking (protocols, IP addresses, Address
Resolution Protocol (ARP), subnets and routing, network ports),
security (TCP-wrappers, secure shell (SSH), Linux firewalls, packet
filtering with iptables, PGP/GPG,
tripwire), NFS, NIS, LDAP, Linux-Windows integration
(dual boot, Samba server), Linux programming, Linux clusters (Beowulf),
E-MAIL and DNS servers.
