Optimizing a Slow Computer



Optimizing a Slow Computer

A fast, optimized computer has noticeably better home and Internet performance. This article describes risk-free tips for a system that is behaving normally.

1) Reboot a computer that's run for several days, or if programs froze recently.

2) Keep at least 25% of each hard drive free. A drive with 10% free space will have performance problems.

3) Run the defragmenter once a month. A disk with little free space, that is also fragmented, definitely has problems. In Windows 2000: Start > Programs > Accessories > System Tools > Disk Defragmenter.

4) If your computer was low-end 2 years ago, or midrange 3 years ago, its overall design is limiting your performance. Upgrading CPU or RAM may help, but the benefit won't necessarily be worth the cost. New desktop computers with reasonable performance for many users can be purchased for well under $1000.

5) Unused programs waste memory and CPU. Don't leave them open or minimize them, shut them down.

6) Any item in Start > Programs > Startup slows your computer booting and will later drain computer resources. It's just as easy to run these programs when you need them. Typical exceptions are an anti-virus, a printer, or a gamma correction program.

7) Remove the Microsoft Office Task Bar, which runs in the background all the time. You can still run the Microsoft programs when you actually need them.

8) While screen savers are fun, they may slow programs, causing some to crash. To conserve your screen and to save energy, turn the power off, or use a power-saver feature.

Avoid "Popular" Ways to Improve Computer Performance

The Internet, Web popups, and newsgroups are full of suggestions to radically improve computer performance. Unless you plan to spend considerable, regular effort optimizing and testing your computer performance, ignore them. It's a good bet that if HP, IBM, Dell or Gateway had a sure method for increasing their computer performance at no risk and reasonable cost — they would have done it. In situations where your computer is mainly used for one thing, say, game-playing or video processing, you can probably optimize it (though at the expense of other programs' performance or features).

Windows XP users might invest a small amount of time to good advantage with Microsoft's How to Set Performance Options in Windows XP. The suggestions are relatively simple and safe, and in any case, the effects can be reversed if something goes wrong.

RBL changes clears spam issues ?

WAS



NOW





After researching for what was like a week, I had to reverse engineer our spam filter system and find how to increase the filter, due to Spam that has just flooded customers who posted emails on major web sites for jobs, and such.

I am posting this to see if others out there see the same issues. if you do simply upgrade your RBL and block the mail from ever connecting or quarantine it. I do both myself.

WISP Setup Recomendations

WISP
Do your research first. Buy complete kits. Buying one piece at a wholesale steal via the net or Ebay is one way, but when you buy a complete kit you have the formula for success.

BCU
buy a bandwidth controller for your Wireless ISP or upgrade to MeshAP Pro on your nodes to get better bandwidth management, QOS and real-time access to data information and more. Without one your sitting with limited access and control of your network.

Syslog
use remote syslog to port system data, errors, and more. System logs need to be collected on a remote server, allowing your access points to operate better since the system wont have log file issues, where you have to reboot, in which you just dumped your log files.

Syslog can run on any OS even an older Windows PC. We recommend VNC for remote access. a 700 mhZ PC with 256 megs ram and 10 gig HD ,running Win2K server.

MESH
Using DLS, cable and multiple carriers is what mesh is really about. The strnght of many outway the alternative spoke and wheel type wireless networks.

The Ultimate VOIP Experiance #7 - VOIP SIP/IAX SoftPhones and their results

Gabcast! The Ultimate VOIP Experiance #7 - VOIP SIP/IAX SoftPhones and their results

10 free softphones downloaded and tested and results.

GNUGK - GNU Gate Keeper & H.323 for VOIP

In my journey into VOIP i ran into a group of guys here in Texas who used this other protocol(H.323) and they lived by it. After I started deploying asterisk PBX based system , using SIP, and IAX, I found exactly what they were talking about. The more I played with it, the more I see why these old timers with VOIP experiance where pointing me here. Enjoy!

link to gnugk site

insert from site:

OpenH323 Gatekeeper - The GNU Gatekeeper
The GNU Gatekeeper (GnuGk) is a full featured H.323 gatekeeper, available freely under GPL license. It forms the basis for a free IP telephony system (VOIP). Please read the manual and the FAQ for general information what a gatekeeper does or take a look at some VOIP and H.323 books to get into the subject.

Features
The GNU Gatekeeper is very stable. It is being used commercially by many organizations to provide VOIP services. They provide executables for Linux, Windows, FreeBSD, Solaris and MacOS X

  • can be run as a Windows service
  • accounting and call authorization via SQL database, Radius, file or external application
  • flexible call routing
  • number rewriting (calling and called)
  • support for NAT traversal
  • full H.323 proxy
  • TCP interface to applications
  • CTI functions (eg. VOIP call-center, call transfers)
  • gatekeeper clustering support (neighbors, parent/child, alternates)
  • H.235 security
  • graphical user interface
  • and it's free, including source code
Compatibility
The interoperability list shows a lot of equipment GnuGk has been used with.
In addition to the general settings explained in the manual there are some specific configuration notes how to configure gateways from some major vendors for use with GnuGk.

More coming soon. I will be adding scripts and option examples. I am working on a few examples, and we now operate our own GNU gateway ourselves.

GNU gateway is based on H.323. Link

Why H.323?

What is ITU-T Recommendation H.323? Why have the worlds largest carriers deployed and continue to deploy H.323? H.323 is the first and remains the most powerful international multimedia communications protocol standard, bringing the convergence of voice, video, and data. Built for the packet-based network, H.323 has found a strong home in IP networks, making it the leader in VoIP.

As with other carrier-grade communication protocols, H.323 is a standard published by the International Telecommunications Union. It was approved by the world governments as the international standard for voice, video, and data conferencing, defining how devices such as computers, telephones, mobile phones, PDAs, wireless phones, video conferencing systems, etc., communicate to bring a whole new experience to the user.

H.323 borrows from both the traditional PSTN protocols and the Internet-related standards. By leveraging from both circuit-switched and packet-switched protocol standards, H.323 is able to smoothly integrate with the PSTN, while at the same time send multimedia communications over such mediums as the Internet.

H.323 originated in the mid-'90s as a logical extension of the circuit-switched multimedia conferencing work being done within the ITU-T. Because of this heritage, H.323 interoperates well with a very large installed base of video conferencing equipment. However, H.323 introduced much more capability than was introduced by previous protocols. It brought with it the ability to integrate with the Internet and the World Wide Web (WWW), as well as interface with the PSTN, to provide a range of applications from wholesale transit of voice, pre-paid calling card services, residential voice/video services, enterprise voice/video services, and much more.

With H.323, users at remote locations are able to hold a video call and edit a document together-in real-time over the Internet-using their personal computers. Not only that, but H.323 allows the users to customize their phones or phone services, locate users, transfer a call, or perform any number of other tasks by using an HTTP interface between the H.323 client and a server on the network. H.323 fully embraces the power of the Internet. From the outset, designers of H.323 wanted to create a protocol that would serve well as the Next Generation Network protocol. H.323 significantly lowers the cost of communications and facilitates the rapid creation of many new kinds of services that were never before possible. In addition, H.323 enables endpoints to perform tasks that were previously only possible for centralized servers to perform. H.323 breaks away from the "old technology" model and introduces an intelligent endpoint capable of initiating and accepting calls without dependency on centralized network elements. However, recognizing the business requirements for centralized control in the service provider and enterprise markets, H.323 also allows for centralized control over the endpoint when desired. The level or extent to which a carrier or enterprise wishes to exert control is entirely up to them.

How to deploy your own voicemail server!

First download Trixbox from trioxbox.org and you get your PBX up and running by either downloading the newest version off the net, or by upgrading, you can get simular results. I prefer the upgrade onsly since I already have several PBX's up, running and routing calls.

From within shell type trixbox-upgrade update
trixbox update -update is also the easist way to upgrade from version1.2.3 to 2.0.
and newer.

It should download a script and then just rerun the above command the box
should fly and brag all the upgrades.

Before you reboot, go into web sinterface with same username and password
and reactivate the modules you have previously. I ran upgrade all., twice.
The rebooted and reprogrammmed my menu to the meet the preprogramed
Intelegent Video Redirector (IVR) to grab as directed one item for 1 another for
2 and so on. I add i and t for lost or illegal digits.

Once your setup then you go into your trunk and add your ZAPtel device (
I added three seperate trunks) 1,2 ,3 . I setup trunk one to be used
for inbound calls. Hit my red reload config, and your in business with
voicemail service.

once done hook line into modem. Modem should pickup and menu should be
chosen for announcement. This will play the VI already choosen if you followed
the instructions.

I setup our Zaptel trunck first then routed calls in to the AVI.

Software: www.tribox.org
Zaptel Compatble PCI modem(s) Intel
1.5 ghz CPU: AMD
256 megs ram:
HD: 60 gig seagate
CDROM : 52x
ethernet 10/100 onboard

Thanks for the great bunch that helped concieve build and support the project.

Sipura 1000 and TrixBox PBX Setup.

Download recent distro. We use TrixBox for our primary distros. OS is Centos ,with AMP, Asterisk and Free PBX just to name a few . Best PBX port on the globe if you ask me. Once you have your creation stared dowloading gather tohether a few parts. 1 GHZ CPU with 256 megs ram. the bigger the HD the better. SCSI is even better. We grabbed a 1U system from a local shop and tossed on 1.23 and then upgraded to 2.0. We chose for speed and quality ultra fast and wide SCSI drives.

Once we were able to setup and routing calls, we then wanted to hook up phones and phone systems into our new beast. Heard Sipura was cheap but decent. Bought a couple off Ebay, and gave one to Andre to take snapshots once he setup his PBX connection on our wireless network.

All together he travels about 3-4 miles via wireless signal, then gets sent down to him to his home outside of town in a new suburb just west on 290 east of Elgin Texas. Thanks again Andre' , for the details and testing.

We then took the system for spin and used IAX softphone packages and tested AIX. We then created another PBX and gave it an outside local line,( going to offer free voicemail) and played with SIP.

Seems the world of programers seemed to have left out a few critical things, in developing your PBX. Our was the confusion primarily on the numbering sequences. So many different examples showed different results.

We had to first layour the network and check our the adapter. We tested the adapter inhouse and used a handy 900 mhz phone for calls. Simple and very easy to use once you get passed the configuration. Talk about 10,000 fields.

We picked a refurbished unit from our a co-developer, and started playing with all the simple things an ATA adapter can do. I now carry over 30 new phone systems, adapters, USB phone and gateway adapters. All have different features. The most simple to me was the first
the sipura 1000.

Once I had my sipura knowledge in hand, I then setup my VOIP phone system. I created
both, SIP and IAX setups. Only one protocol per extension. I then created Andre a SIP
account on a remote PBX. The PBX has a real world IP. Andre has a firewall at his house, that runs some ported linux version and then he plugs in the SIpura 1000, and configures away.

After spending who knows how many hours, he calls me (my headset is toast) and complains about my headset sounding like crap. Will do after we unfreeze. Called from my laptop and guess what. He was on the phone.

Guess he got it to work !

I call back later and get right through. He sends over the snapshots of the sipura setup and I do the cut and past web work and upload.

Visit our VOIP setup web site and see the results. I made a few notes for those using other SIP devices and AIX as well. Will do a couple of SIP-PBX configurations videos soon. Please visit our web site and download our toolbar to keep up to date on the network.

BlueQuartz on CentOS

I have hosted web pages on the net since its conception. My first web servers ran on digital 128K connection and have expanded ever since to gigabit Fiber nationwide with redundant power, hardware and backbones.

I will be writing on my experiences on BQ on CentOS from a providers point of view.

Blue Quartz?

It all started when Cobalt Networks released its first 1 U complete hosting solution. Being one of the largest central Texas developers at the time, we became a Cobalt dealer, and moved hosting to it's platform.

Since those days , allot has happened. Cobalt sold to Sun who end of lifed but released the source code of the Cobalt OS. We built hundreds of different hosting solutions, and came news of OS's that will run on PC and looks and feels just like latest Cobalt OS.

Before we get started ( see next post) lets go over a few things that I think hampered the results. First do your research and development behind a firewall. Why ? Once you jump live onto the net your PC or box as we call them, can and will get taken over in a matter of weeks.

After trying several OS's one thing was centrain that each OS was dependant on security risks from PHP, MySQL, SSH, Bind, and on and on. Once a security risk apears anywhere in the "open source culture" you can expect it to be exploited to its fullest. The newer the network may buy you time, but once you start announcing traffic to the server, you better have it tighened down beast first.

The best free firewall I played with on CentOS was IPtables. if your remote be sure to add your SSH ports before activating the firewall rules and cutting off your connection.

Blue Quartz
Download BlueQuartz
CentOS
IPTables

As aways back up any data you want before playing with any new package. I recommend installing blue quartz on a least a 1 ghz PC with 40 gig hard drive, half a gig of ram with CDROM. 10/100 megabit ethernet card a must.

Dowload Cd from link above. RTFM. I can not emphasis the importance of reading the manual.
Boot from CD and OS will wipe off HD and setup CentOS, PHP, MySQL, Bind, Sendmail and then install Blue Quartz on top of it all. WARNING. OS load will wipe all existing data off drive.
