• Redhat Linux Docs. These docs are still the best available online for Fedora.
• Helpful documents for Linux beginners. Read the Linux Directory Structure link.
• Signal encoding techniques
• Spanning Tree Protocol. (cisco doc)

• IP Routing Primer - read ALL the parts!
• Linux Advanced Routing Howto (Read at least sections 4 and 5)
• Guide to Linux Network Administration
• Cisco router configuration tutorial
• DNS HOWTO, RFC 1035 on DNS, Redhat DNS configuration.
• The Packet Filtering HOWTO. Read this document several times; carry it everywhere you go for a week. Eat and sleep with it. (printable version).
• another iptables howto
• Network Address Translation HOWTO. This is just as important as the packet filtering howto
• Different types of NAT
• Longer, more advanced iptables tutorial. (Read chapters 6 and 7)
• TCP finite state machine
• Note on active versus passive ftp

Packet filtering lab and assignment. Sample Solutions

NAT Lab and assignment (including textbook problems from chapters 4 and 5).
Support programs: udp sender, udp receiver
For extra credit problem: TCP torture client and server, UDP torture client and server

Sample Programs:

• Basic file IO programs in C, Java and Perl.
• Skeleton tcp client and server in C
• Skeleton tcp client and server in Java
• Skeleton tcp client and server in Perl. (perl programs also require byte ordering routines)
