# What is CPAN? How do you access it? comprehensive perl archive network - free perl modules. cpan.org search.cpan.org
# What advantages does mod_perl have over a perl CGI? speed, stability and integration.
# What is required to do SSL in Apache 1.x? openssl, mod_ssl, apache. Unless of course you grab a precompiled binary! :)

1. What ports does FTP traffic travel over? 21
2. What ports does mail traffic utilize? SMTP 25, POP3 110
3. What ports do HTTP and HTTPS use?
HTTP 80, HTTPS 443
4. Why is NTP required in an NFS network?
NFS, the Network File System, has long been known for its remote exploits and vulnerabilities. Even secure NFS has vulnerable points. However, NFS is also a very reliable means of copying and backing up systems to a central backup server. In order to synchronize the backup clients with a central backup server extremely accurate timing is needed. That’s where NTP comes in.
5. Name some common mal software on the server side
DeepThroat, BladeRunner, Hackers Paradise
6. What is CPAN? How do you access it?
Perl programmer’s paradise!
7. What is PEAR?
PHP programmer’s paradise!
8. What advantages does mod_perl have over a perl CGI?
CGI is one of the first methods of creating dynamic web content.
The problem is that it forks a new process and loads a copy of the interpreter
for each request, using too much memory.mod_perl includes the Perl interpreter
within Apache.
9. What is required to do SSL in Apache 1.x?
10. What is Tcl? a scripting language “born out of frustration”
used for rapid prototyping, GUIs, testing and CGI scripting
11. What is a servlet engine/container?
An application server that provides the facilities for running Java servlets. Also called a “servlet engine” and “servlet womb,” examples of servlet containers are JServ and Tomcat from the Apache Jakarta Project. Today, servlet containers also support JavaServer Pages (JSPs) by converting them to servlets. For example, Tomcat supports JSPs, but its predecessor, JServ, did not. Full blown J2EE-compliant application servers generally handle servlets, JSPs and Enterprise JavaBeans (EJBs).
12. What is BIND?
BIND (Berkeley Internet Name Domain) is an implementation of the Domain Name System (DNS) protocols and provides an openly redistributable reference implementation of the major components of the Domain Name System.
