No more spyware!
Eliminate spyware with Outpost’s dedicated antispyware utility. Regular updates and always-on monitoring ensure that spyware cannot activate and cause damage to your data or divert your applications.

Secure web surfing
The versatile Web Control module safeguards you against the Internet’s darker side. It steers you away from websites infected with drive-by downloads, prevents the inadvertent disclosure of personal information, limits your exposure to potentially unsafe web properties, and keeps your identity private.

Bulletproof self-defense
Outpost cannot be deactivated by targeted attacks, ensuring continuity of protection.

Performance-driven operation
No matter what you do on an Outpost-protected computer, it will always feel like it’s brand new because the program uses so few system resources. The key engine has been optimized to deliver revolutionary speed efficiency, so you can focus on using your computer productively, not worrying about security issues.

Apache SSL and Certificate Authority(CA) | Howto

Tech Blog - Here is a simple howto on creating your own CA or Certificate Authority unders Cent OS 5, this howto would also work on other Linux distribution with modification to path where the command could be found, this howto covers creating a certificate authority using OpenSSL and setting up a secure website using Apache with mod_ssl module.

For Cent OS 5, you will need to have Openssl, Apache with mod_ssl module, and Openssl tools(openssl-perl), you can easily serach for this packages using the yum tool, yum search , make sure that mod_ssl is being Loaded on httpd.conf

Now lets begin with the howto

If you have all the above files installed on Cent OS 5, the path to configuration files below will work for you.

Apache SSL Configuration File - /etc/httpd/conf.d/ssl.conf
Openssl Configuraltion File - /etc/pki/ssl.conf - Openssl Perl Script tools - /etc/pki/tls/misc

Creating a new Certificate Authority

$ ./ -newca
Press Enter to create. - then enter a difficult passphrase do not forget this passphrase
Fill in your details and provide a sensible name for the
Common Name (eg, YOUR name) []:

This creates a new CA certificate in the directory /etc/pki/CA. The CA's self-signed certificate is stored in /etc/pki/CA/cacert.pem and its private key is in /etc/pki/CA/private/cakey.pem. make sure to secure this files.

Certificate Request

Now you need a server certificate that is signed by your own CA. First, generate a certificate request. Fill in the details and make sure "Common Name" is the hostname of the website.
$ ./ -newreq Produce a passphrase for the server certificate. Common Name (eg, name) []:

The certificate request are in newreq.pem.

Now sign the request as the root CA,

$ ./ -sign Enter the passphrase for the root CA. Enter the passphrase for the server certificate.

The server certificate is placed in newcert.pem. The private key is saved in newkey.pem.

Make sure the private key is never world readable. Secure the PEM files including newreq.pem for later use and make sure they are kept private..
$ chmod 0400 newkey.pem

Adding Certificate to your Apache ssl.conf

Look for the following lines under /etc/httpd/conf.d/ssl.conf

SSLCertificateFile /pathto/newcert.pem
SSLCertificateKeyFile /pathto/newkey.pem
SSLCACertificateFile /pathto/cacert.pem

Make sure to Uncomment the following lines as well

SSLVerifyClient require
SSLVerifyDepth 10

Then restart Apache /etc/init.d/httpd restart it will ask you to enter the passphrase you use for the CA

Creating Client Certificate

You can recreate a newreq.pem and newkey.pem, or just use the ones you have generated before, now we will combine newreq.pem and newkey.pem and convert them into the PKCS#12 format that can be imported to our browser..

$ cat newcert.pem newkey.pem >> signing.pem $ openssl pkcs12 -in signing.pem -out signing.p12 -clcerts -keysig -export

Enter the Passphrase then Enter a password for export. When importing the the p12 file to your browser you will be asked for it again.

Now you should see a file named signing.p12, download it to your desktop then import it to your browser, then thats it.

If you wanted to generate ceritificate for a lot of individual or make a script of it you can use

$ openssl pkcs12 -passin pass:yourpassphrase -in signing.pem -passout pass:yourexportpassword -out signing.p12 -clcerts -keysig -export

How to Kill Defunct Process in Unix

Tech Blog - A "defunct" process or a zombie process is a process that is actually finished which depends on a parent process, which for some reason usually due to error did not terminate.

You can usually see defunct process using the ps -ef command, this process mostly are harmless and can be left alone, however they are annoying in my opinion so I often want them removed, the catch is you can't kill an already dead process, good thing Unix has a utility that will help us removed it.

preap forces the parent of the process specified by pid to waitidfor pid, if pid represents a defunct process.

preap attempts to prevent the administrator from unwisely reaping a child process which might soon be reaped by the parent, if:

The process is a child of init.
The parent process is stopped and might wait on the child when it is again allowed to run.
The process has been defunct for less than one minute.

Using preap

$ preap pid

E-mail Attachment | Ubuntu Command Line | Howto

Tech Blog - Here is a very usefull command on sending files as attachement on Linux/Unix command line, this is specifically very usefull when using it in script to send daily report, or just for mailing client certificate directly from the server, there are two ways I know that you can use to send a file as attchemnt using command line, one is using uuencode utility with the "mail" command and the other one using "mutt", I find using mutt command to be much more reliable compared to using uuencodeutility with mail command.

uuencode utility writes an encoded version of the named input file, or standard input if no file is specified, to standard output. The output is encoded using the algorithm described in the STDOUT section and includes the file access permission bits of the input file and the decode_pathname, for re-creation of the file on another system that conforms to this specification.

If you don't have uuencode command on your system, and your running Cent OS or Redhat distribution you can find the uuencode and uudecode on the “sharutils" package.

To send a file attachment using "mail" command
$ uuencode filename.jpg filename.jpg | mail -s 'subject'

To send a file attachemnt using "mutt" command
$ echo | mutt -a filename.jpg -s 'subject'

Mutt is a small but very powerful text based program forreading electronic mail under unix operating systems,including support color terminals, MIME, and a threadedsorting mode.

Thats it!

Smart Bro | Smart Bro Broadband | Review

Tech Blog - This is an update review of Smart Bro Broadband Service I did last year which can be found here, After subscribing to their service for one and half year I have finally decided to discontinue their service, my primary reason is their pathetic customer service and long down time period, for the first year of my subscripton down time and customer service are in acceptable level meaning, down time and issue related to it are resolve within a day and calling Smart Bro customer service hot lines will get you in contact with an actual person not that that person can actualy help you since like what I have mentioned before on my previous review that their customer service representative(Level 1 and Level 2 support) are pretty useless and incompetent and doesn't know what terms like DHCP, IP means or even have and idea of how a router and their own equipments work, recently I have experienced down time and intermittent connection varying from 2 to 3 days and lately 4 to 5 days without any resolution calling their customer service hot lines is even more frustrating it is specifically designed to annoy and irritate customer, Smart Bro service have gone down hill since I have initially subscribe last year, I wouldn't recommend it to anyone, if you are currently a subscsiber below are some tips on getting some customer service by calling the hot lines, if you are not a subscriber yet and thinking of getting Smart Bro Broadband I wouldn't recommend it save yourself the pain and frustration of dealing with them and their crap service, Smart Bro is dedicated to delivering underwhelming and overly frustrating slow and undependable internet and customer service to you.

Tips and Steps on getting to a Smart Bro customer service(Actual Person) if your having problem, this is all from my personal experience dealing with them as their subscriber.
  • Smart Bro Customer Hot Line - 6727277
  • When the machine answer press 1 for technical problem
  • Then press 1 again to continue, don't bother listening to the voice
  • Then it will ask you to enter your 10 digit number or service reference number, if you want to talk to an actual person just type in any(WRONG) 10 digit number then press #
  • Then press 1 again to confirm the incorrect service reference number
  • You will be redirected to an Level 1 support person, the support person will ask you to tediously one by one go down their list of troubeshooting procedure script, if your a technical person and you know it not your problem ask them to connect you to an Level 2 support, if your not you might want to actually go through it or ask some friends that knows how to actually troubleshoot do it for you than do what Smart Customr Service representative ask you to do, if the Smart Bro Customer Service Representative is telling you that the report has been created and sent make sre to insist for an ETA and insist that you be connected or transferred to someone who could give one, remeber they are not allowed hang up the call, so milk it till you get what you want.
  • Level 2 support will again try to guide you through their useless troubleshooting script which they themselves don't understand, again ask them to escalate you to their "special case group"
  • "Special Case Group" basically has more technical expertise and have access to the engineer in terms of updates, but they are pretty much in the blind too basically their useless but this is the only actual way of getting logical and more informative help from Smart Custmer Service.

If your a Non technical person and you can't troubleshoot or identify your own network problem, I suggest you get someone who knows, because you will spend hours and days jumping through hoops with no result and improvement to your problem.

NOTE: their internal SLA is 24hours for every report they make, however it does not mean anything since they create a new report every time you call even if its for the same problem.

I hope you find this Smart Bro Review useful!

Console "debug" Prompt

Tech Blog - Recently I encountered and error on one of my servers it reported that the host is down when i logged into the ALOM console, I found it in debug prompt anyway If you find yourself having an ALOM on debug prompt believe me there is something very wrong on your server :) probably hardware related issue, a screen shot of my terminal screen below I also discovered that send breaks to the console does not work and the only thing that did work was to power cycle the server.

Before doing a power cycling I checked the console logs, which didn't show anything that would tell the cause of the host crashing

debug: sc> showlogs
Log entries since SEP 23 07:58:33 ----------------------------------
SEP 23 07:37:33 servername: 0004004f: "Indicator MB.ACT is now OFF"
SEP 23 07:39:57 servername: 0004004f: "Indicator MB.ACT is now ON"
MAY 11 06:07:59 servername: 0004004f: "Indicator MB.ACT is now OFF"

MAY 11 06:10:37 servername: 00040002: "Host System has Reset"

MAY 11 06:10:38 servername: 0004000b: "Host System has read and cleared bootmode."

showenvironment command also didn't show anything is wrong

After reseting the host the error below pop up
0>ERROR: TEST = Block Memory
0>H/W under test = MB/P0/B0/D0 (Bank 1), Motherboard

0>Repair Instructions: Replace items in order listed by 'H/W under test' above.
0>MSG = Pin 69 failed on MB/P0/B0/D0 (Bank 1), Motherboard 0>END_ERROR

So obviously it is a hardwae problem, initially I thought it was the motherboard but a closer look it was one of the dimm, anyway I ended up calling the vendor and have the part replaced, use the showfru command to identify the parts needed, you must be on the sc> to do the showfru command.

ERROR: Inconsistent password files | Ubuntu Howto

Tech Blog - Here is a short how to on fixing "ERROR: Inconsistent password files" when adding or modifying user account on Ubuntu Linux or Unix operating systems, usually the cost of this error are there are some error entries or on the passwd line such as missing GID or other credentials.

Attempt to add user get the error below
$ useradd ironman

So we try running pwconv as suggested, the pwconv command alert us that there is a problem on line 172 to line 175 of the passwd file
$ pwconv
pwconv: ERROR: bad entry or blank line at line 172 in /etc/passwd
pwconv: ERROR: bad entry or blank line at line 173 in /etc/passwd
pwconv: ERROR: bad entry or blank line at line 174 in /etc/passwd
pwconv: ERROR: bad entry or blank line at line 175 in /etc/passwd

We go cd to /etc then backup passwd befor we edit passwd
$ cd /etc $ cp passwd passwd.20090910

Now that we have a backup incase something goes wrong do vi passwd, and go to the lines above and see if there are incomplete entries on thos lines, sometimes its is just a blank line with space, you will need to delete the lines.

$ /usr/bin/find / -xdev -size +50000000c -exec ls -lt {} \;

Find and delete core file on your system
$ find / -name core -exec /bin/rm -f '{}' \;

Hope this help.

Combined Community Codec Pack | CCCP | Review

Tech Blog - If your looking for a good codec pack for your Windows system I would suggest you look into CCCP, it will probably play any media files you have and will probably the only medi player you will need, it is a very good alternative to Windows Media Player and even VideoLan(, howver make sure that you do not install CCCP as well as VideoLan on the same system, base on experience this will mess up your codec packages on Windows and soemtimes will need a reinstall of Windows to fix the issue anywa more details and on what CCCP is from their website.

CCCP was created to replace the video playback packs provided by several anime fansub groups in favor of a single reliable pack capable of decoding practically any groups' files - without breaking compatibility for other formats. Since then it has grown into a pack that can decode more or less anything that you will run into during your travels on the internet.
