Compliance Forge
We take care of the tedious and time-consuming work that is associated with writing comprehensive cybersecurity documentation. By doing this, we offer a unique service to businesses - we can provide you with semi-customized IT security documentation, based on industry-recognized leading practices that include ISO, NIST, OWASP, CSA and others. This allows you to quickly obtain professionally-written IT security documentation and you have the ability to edit this documentation for your specific needs, since it comes in Microsoft Office formats. This is beyond buying an "IT security policy template" online - these products allow you to have the same level of professional quality documentation that you would expect from hiring an IT security consultant to write it for you. Please take a few minutes and look at the examples to see for yourself!

Our comprehensive written information security documentation includes the policies and standards that businesses need to meet common information security requirements, such as PCI DSS, HIPAA, FACTA, GLBA, as well as unique requirements like FedRAMP and NIST 800-171 compliance. We've been doing this since 2005, so we have a long track record of successfully writing IT security policies and other compliance-related documentation, such as risk assessments, vulnerability assessments and audit templates. Everything we do centers around providing your company a solid set of cybersecurity policies and standards to use as a foundation to build from!

Install Dropbox In An Entirely Text-Based Linux Environment - The Unofficial Dropbox Wiki
dropboxd will create a ~/Dropbox folder and start synchronizing it after this step! Go to the URL given; you should see a success message at the top of your screen.

NOTE: If you want to change the account it is linked to, unlink it from the first account, then kill the running dropbox process, start it up again (with “~/.dropbox-dist/dropboxd &”) and obtain the new host_id with dbreadconfig.py . If you don’t restart the dropbox client, it will give the same host_id (which for some reason cause me to be unable to change the account it is linked to).

How to Remove XP AntiSpyware
AntiSpyware XP was the problem that prompted my friend to call, and it was the most hostile, insidious, and difficult-to-kill malware I've ever seen. It looked completely authentic and felt impossible to stop. Masquerading as a spyware killer itself, in the system tray, its icon was an almost perfect replica of the Windows Security Center icon. When you tried to visit a web site in Internet Explorer or do much of anything, XP AntiSpyware launched, and its window looked just like Windows Security Center. Once launched, it would start scanning your PC automatically, and tell you, in alarming red pop-ups, that dozens of files were infected and that you should delete them. There was no quit, there was no uninstallation available in Add/Remove Programs, and all the program's options in its Settings area were grayed out/disabled.

PiaF to Avaya IP Office 403 via H.323 - PBX in a Flash Forum
In my searching I found very little information on H.323, so I thought I would post what worked for me.

Goal: Connect PiaF to 3 different Avaya IP Office 403 units.
Problem: The 403's only support H.323, not SIP or IAX.

From a default PiaF install (used the 1.5 Beta for driver issues) I only had to do five things.

1. Edit ooh323.conf
2. Add trunks
3. Add outbound routes
4. Add new VoIP line in 403 units
5. Add short code in 403 units

OpenH323 - PBX in a Flash Forum
I'm fairly certain that H323 is installed on Piaf by standard. but to check, do the following.

cd /usr/src/asterisk-addons
make clean
make menuselect ; check H323 channel driver is enabled.
make install

You will need a copy of the h323 conf file, usually on a bare asterisk install you would simple do make samples, don't do it here, because it will overwrite all sorts of stuff in /etc/asterisk you don't want overwriting.

It should then be a question of configuring the h323 file to suit your carrier.

debian_asterisk_freepbx_script [Core Networks]
The script has been updated with the latest Asterisk versions (1.4) and now has some basic error checking for when the script is interrupted. There should be no need for manual workarounds with the new script. If it is interrupted, simply restart the script and it should recover.

took all the suggestions from those listed below and incorporated them into the script
Fixed a few typos
fixed dependencies with Dahdi hardware

This script will download and install Asterisk, freePBX on a debian system (currently Lenny 5.0). Have a look at the script, you will need to make sure that the versions of Asterisk listed in the script are current. If you dont change them, the script will still work, you just wont have the most recent version of Asterisk installed.

The goal was to make this as easy as possible with the least amount of user interaction.

CentOS 5 and Asterisk 1.4.x installation - voip-info.org
For reasons detailed elsewhere, you're best not using a GUI, so do the installation from the command line ('linux-text' at the GRUB prompt). When you select the packages, the only one you need is 'server'. Disk partitioning, networking etc. is all entirely up to you!

At your first login, you'll be presented with a simple administration screen. Disable SELinux and (for now) the firewall.

Asterisk in a Xen domU with ztdummy | Vancouver Linux Users Group
The problem with ztdummy under Xen is that it expects to have access to the rtc (real time clock) on x86/x86_64 systems, but that is not the case in a Xen domU. The fix is to comment out the #define USE_RTC statements in ztdummy.c so that ztdummy uses the kernel timer.

While googling I saw references to checking the HZ setting in the kernel (mine claims 250HZ in the kernel .config) and adjusting the #define ZAPTEL_RATE 1000 in ztdummy.c accordingly, however when I changed it to 250 asterisk's menu audio played back four times too quickly. Switching ZAPTEL_RATE back to 1000 solved this problem and the interactive voice menus played at the correct speed.

I wasn't quite finished. With ztdummy loaded my moh became very garbled whereas before it had played properly. Switching asterisk moh from mpg123 to files (in /etc/asterisk/musiconhold.conf) and my mp3s to 8kHz 8bit mono wav files fixed moh.

I now have Asterisk with MeetMe and moh working properly in my Xen domU.

Handle VoIP Traffic with the PIX Firewall  [Cisco PIX 500 Series Security Appliances] - Cisco Systems
In this sample configuration, a PIX Firewall is configured in order to allow the traversal of two different Voice over IP (VoIP) protocols—H.323, and Session Initiation Protocol (SIP). Due to the fact that VoIP protocols are made up of signaling and IP address/port combinations, there are a number of issues with VoIP and Network Address Translations (NAT). The PIX Firewall fixup protocol addresses these issues.

IPtables Examples
These rulesets are in iptables-save format. I have written some simple documentation of the iptables-save format. I use this format for several reasons: it ensures there are no other rules in iptables, it loads faster, it avoids the possibility of a race condition that most iptables scripts have (although the race window would be about 1ms for most rulesets).

The Art of System Administration
Main Entry: troubleshooter

1. a skilled worker employed to locate trouble and make repairs in machinery and technical equipment
2. an expert in resolving diplomatic or political disputes : a mediator of disputes that are at an impasse
3. a person skilled at solving or anticipating problems or difficulties

This is a fitting definition of a system administrator - making repairs, dealing with people, and trying to anticipate as well as prevent problems.
