1 – None, FTP only makes necessary changes for compatibility.
2 - This file will be corrupted, resulting in a program that will not executable.
3 – When you would download a public file.
4 – You would enter the following command on the command line n /etc/vsftpd/vsftpd.conf: local_enable=NO 5 – SFTP is secure whereas FTP is not.
6 – The cd command changes the remote working directory; and the lcd command changes the local working directory.
7 – The server has blocked that port. An administrator may have disabled that port.
8 – Running vsftpd in the chroot makes it a lot more unlikely that a malicious user can exploit the system. VSFTPD does not run as root by itself, if ran in just root a user may stil be able to exploit the system where as using chroot is harder for a malicious user to exploit the system.
9 – You could use Free MD5 Checksum or Hashing Software
10 - To configure vsftpd to run through xinetd, set listen=NO in /etc/vsftpd/vsftpd.conf, and create a xinetd configuration file for vsftpd in /etc/xinetd.d.
Chapter 26 Exercises 1 -10
1 - DocumentRoot "/usr/local/www" and <Directory "/usr/local/www">
2 – Change the setting in httpd.conf, Listen 80 to Listen 81
3 - Just add an Alias and Directory directive to Sam’s site Alias /sam
4 - Apache listens on port 80 by default; port 80 is a privileged port. Only root can use privileged ports, so you must start Apache as root.
5 - Sset the interface that apache listens on in httpd.conf file.
6 - CGI script requires a system call to fork() and exec() to create a new process.CGI runs fast and terminate as soon as complete.
7 - Authentication integrity
8 - The same data is generated each time a web page is accessed, using CPU and disk resources at each access. Using these resources unnecessarily could result in pages being unavailable when the system load is high.
9 – You can set up a named virtual server and set the document root for mail.example.com to be /var/www/webmail. Then you can set another virtual server for example.com and set the document root for that to e.g. /var/www/html.
10 – First you would set the following in httpd.conf: <Directory /var/www/html/corp> Order deny,allow Deny from all Allow from 192.168.</Directory>
Second create the following .htaccess file in the intranet directory: Order deny,allowDeny from all Allow from 192.168.
