VTC - INTRODUCTION TO APACHE WEB SERVER

Apache is probably the most popular Linux-based Web server application in use.Web sites both personal and commercial can be very rewarding exercises as they share your interests with the world and allow you to meet new people with whom to develop friendships or transact business.Unfortunately,even the best Web sites can be impersonal as they frequently only provide information that the designer expects the visitor to need. E-mail, although ancient in comparison to newer personalized interactive Internet technologies, such as IP telephony and instant messaging, has the advantage of being able to relay documents and other information without interrupting the addressee. This allows them to schedule a response when they are better prepared to answer, a valuable quality when replies need to be complex.

Linux | Unix operating systems via ubiquitous tools such as: grep, awk, sed, Perl,
PHP, etc., and provides systems administrator/engineers and developers alike, the
ability search, time-effectively, considerable amounts of textual data, using literals,
character classes, metacharacters, metasequences, etc.

Let LinuxCBT RegEx Edition cost-effectively teach you Regular Expressions!

Recommended Prerequisites for:

* Any LinuxCBT Operating System Course (Classic/EL-4/SUSE/Debian Editions)

LinuxCBT IPv6 Edition

LinuxCBT IPv6 Edition focuses exclusively on the burgeoning Internet Protocol Version 6 (IPv6).



The coursework explores IPv6 implementation on today's mainstream Network Operating Systems (NOSs), including: GNU/Linux, Solaris, Windows and Cisco IOS.

Given the imminent depletion of globally-unique 32-bit IPv4 addresses, and mandates set by the US Government with respect to IPv6-backbone-compliancy by Q2 2008 for government agencies, Information Technology (IT) Network/Systems Engineers/Administrators/Integrators/Directors/etc., are tasked with preparing their backbones and applicable infrastructure(VLANs/DMZs/etc.) to support Internet Protocol Version 6 (IPv6).

LinuxCBT IPv6 Edition will prepare you and/or organization to comfortable integrate IPv6 into your production environments, without negatively impacting IPv4 services.


Recommended Prerequisites for:
Any LinuxCBT OS Edition such as LinuxCBT feat. SUSE® 10 Enterprise Edition
Open mind & determination to master Linux and related open-source applications
Basic MS Windows skills
Basic understanding of networking concepts
Access to a PC to perform all of the installations and exercises

Creating CD-ROM ISO image in Linux

dd is a perfect tool for copy a file, converting and formatting according to the operands. It can create exact CD-ROM ISO image.

This is useful for making backup as well as for hard drive installations require a working the use of ISO images.
How do I use dd command to create an ISO image?

Put CD into CDROM

Do not mount CD. Verify if cd is mounted or not with mount command:

# mount

If cd was mouted automatically unmout it with umount command:

# umount /dev/cdrom

OR

# umount /mnt/cdrom

Create CD-ROM ISO image with dd command:

# dd if=/dev/cdrom of=/tmp/cdimg1.iso

Where,

* if=/dev/cdrom: Read from /dev/cdrom (raw format)
* of=/tmp/cdimg1.iso: write to FILE cdimg1.iso i.e. create an ISO image

Now you can use cdimg1.iso for hard disk installation or as a backup copy of cd. Please note that dd command is standard UNIX command and you should able to create backup/iso image under any UNIX like operating system.

13 security practices for SysAdmins

This information has been compiled to help system administrators certify that good security practices are being used BEFORE a computer is connected to the network.

Installing System Patches

It is recommended that based on the requirement, you install every patch recommended for your computer which isn’t
yet installed. Since some patches restore default configurations, it’s important that patches are put in place before any further security precautions are taken.

Before Recording System Defaults

Before starting to record system defaults, a directory should be created to store them. For example;

mkdir /usr/adm/checksIf an unauthorized user does gain access to root privileges on the computer and changes the accounting system, the
administrator will still have an original copy of it for comparison. For safety, the system administrator should check the files against the original about once a month.

Recording SUID and SGID Programs

Before any software is added to the basic operating system release, the system administrator should check for SUID and SGID programs. If unauthorized access occurs, frequently the intruder will leave a program that enables privileged
re-entry. The list of SUID and SGID programs should be stored both on and off the computer. The version on the computer will be used by a daily cron job to check for changes, while the version stored off of the computer will ensure that even if root access is acquired, a record of the system’s original state is available.

The command to list SUID and SGID files is:

find / -type f \( -perm -002000 -o -perm -004000 \)-type f: looks only at regular files-perm: checks for permissions-002000: checks for SGID programs-004000: checks for SUID programsCheck and Record Permissions on all Device Files

By changing the permissions on device files, an unauthorized user can gain access to devices, using this access to change files, impersonate another user, or listen in on conversations. Record the permissions on the device files on and off the computer using:

ls -al /dev/* sort > /usr/adm/checks/devicesPasswords and Shells on System Accounts

Check the system password file to ensure that all accounts have passwords. Many vendors ship their computers with no passwords on the system accounts. System accounts such as bin, lp, and sync should have a ‘*’ for the password field. No account should be left without a password.

Also, the system administrator should check to see if the computer comes with any passwords already assigned. Some
vendors give default passwords to system accounts. Since anyone who has the same type of system knows what the default passwords are, passwords should be changed immediately.

Every account needs to have a shell assigned to it. Most administrative accounts should have /bin/nologin as the shell, which
would disallow crackers from gaining shell access using obscure system holes.

Expire Inactive Accounts

Computers with large numbers of users tend to have accounts that become inactive. The beginning of a new fiscal year often
brings changes in who is using the computer, as users’ funding sources change. The system administrator needs to be sensitive to those accounts that become inactive, and disable them by replacing the password field in the /etc/password file with an ‘*’. If the user has left important data on the computer, eventually they will contact the system administrator to make arrangements to retrieve the data. Once this data is retrieved, the account should be removed.

Restrict Root Login to the Console

The ability to login to the root account should be restricted to the console. Anyone not at the console should have to use ’su’ to
become root. Tries to ’su’ are recorded in a file in /usr/adm such as /usr/adm/sulog, for accounting purposes

Check for Duplicate Groups

Replace any duplicated group with a group of its own. This will remove ambiguity and make membership in a group clearer.

Do Not Establish Guest Accounts

Do not establish accounts for guest usage. These accounts, often appearing as an account with login guest and password
account, are common holes exploited by unauthorized users. Every user of the computer should undergo the same security procedures, receive the same security briefing, and be held accountable to the same standards. When users are finished using the computer, their accounts should be removed from the password file.

‘remote’ Commands

Commands preceded by the letter ‘r’, such as ‘rlogin‘ or ‘rsh‘, should be disabled. They are a source of many attacks on sites
across the Internet. If you must use ‘r’ commands, make sure you filter the TCP ports (512,513,514) at the router; it is important to note this will only stop outsiders from abusing the commands.

Double Check the System Before Long Weekends

Double check the computer before long weekends to ensure there are no security problems with it. A backup just
before a long weekend is advisable.

Do a Monthly System Check

Run the cron script against the cron stored on the removable media in case the unauthorized user gained root access and altered the system without being noticed.

System Security Diary

Keep a diary of the security checks done on the computer and what their results are. Also, document what actions are taken if holes are found or problems occur. If there is a problem, others will want to know what the system administrator has been doing to secure the computer.
