Is your computer infected? PDF Print E-mail

Those who are entering the computer world tend to get a bit nervous; and why not? There is a constant creation of viruses, Spyware and Adware that could potentially sabotage your work and exploit your privacy. Unfortunately, there isn’t always a warning sign upon entering websites, and when there is, you have to beware that that isn’t the virus.

Think of spyware programs like a nasty cold that you just can’t kick. It basically hides in your system, destroying you from the inside-out. It has the ability to watch your every computer-move. What you once thought was your private information can now be a public display to anonymous users. Anything residing on your hard drive can be visible through this Spyware Program.

Common Symptoms: Constant Pop-ups, Unusual changes to your toolbars and/or icons on your desktop.

 If you are experiencing any of the above symptoms, you may want to run a system scan. By doing so, you’ll find out whether or not you have Spyware. If you do, make sure you don’t stumble across more. Here’s what I mean. There are tons of products that will help you overcome this problem, but beware. Before installing the software, make sure it’s credible! There are many tempting offers on the internet for Spyware solutions but they may be scams! If you go forth with what you think is accurate software, you could be digging a deeper whole. Don’t feel bad, it’s happened to most of us.

Have you ever downloaded freeware, and as soon as the download is finished you received multiple pop-ups? They usually read, “There is a problem with your computer, would you like to fix this problem now?” 

Naturally, you press Ok. Now, your computer starts acting up even worse than before. Well, that was not a credible site.

Tip: Don’t press any button they have available to you (Ok, Yes, No, Accept, Fix Now). Just click the little ‘x’ at the top-right corner of the box.

The prescription: AntiVirus on its own is not strong enough to protect your computer from potential threats. Make sure you have all the right software. Software with an auto-update for spyware definitions is ideal because new spyware definitions are being added every day. AntiVirus and a spyware removal program (aside from your existing anti-virus software) would be the perfect prescription to kick that nasty cold.

 As soon as you realize any strange activity with your computer, check it out. The sooner you catch the problem, the easier it is to fix it and after you find out it’s a legit solution, go for it!

 
Rebuilding a Broken Raid in Openfiler 2.3 PDF Print E-mail

NOTE: If more than 2 drives fail, you may have to do an interactive startup to stop the auto alarm posting of the "Iscsi target" service.  The alarm will hamper entering of the command.

If you are trying to use OpenFiler 2.3 as a storage repository for Citrix XenServer and a drive fails or the raid is broken, OpenFiler does not automatically repair the raid if a new drive is added or the issue with the previous drive is resolved and it is reinstalled. You have to re-attach the volume(s) manually to the raid device in Openfiler.

To see the members of the raid device, login to the OpenFiler GIU via your web browser --> volumes --> software Raid, then click on view members.  Here you will see the Raid configurations and which drives/volumes have been detached. Alternative methods would be to view the OpenFiler error email or execute the following command at the CLI (command line interface):

cat /proc/mdstat

The above command prints on the current system raid settings.

 

To reSync the array device, you must use of the “mdadm” command from the CLI:

mdadm /dev/md0 --add /dev/sdb1

The above example adds the partition/volume sdb1 to the raid device md0.

The status of the rebuilding/syncing of the raid can then be seen from the web interface of OpenFiler:  Volumes --> Software Raid.

Traditional vs. SSD - Internal Testing PDF Print E-mail

Performance of WD Raptor 10K RPM 160GB RAID 1:

Performance of Crucial 128GB SSD:
alt


Items to note:
1. The WD Raptor transfer performance degrades while the SSD is consistent across the entire test.
2. The burst rates are very close.
3. The access time hands down goes to the SSD.  .1 ms vs 8.5 ms for the WD Raptor. 

Not all SSDs are created the same.  The one from Crucial.com actually has one of the fastest transfer rates I have seen.

DDoS Mitigation – Best Practices PDF Print E-mail

Although distributed denial of service (DDoS) attacks have become a mainstay of hackers’ arsenals, their profile has changed considerably in the past year or so, making them an even greater threat to companies that conduct business online or have significant investments in their online brand and reputation. DDoS attacks are larger, stealthier, more targeted, and more sophisticated than ever. Increasingly, even amateurs can execute attacks themselves or cheaply rent botnets to do the job for them. Given the extraordinary and rapid changes in the DDoS terrain, traditional DDoS mitigation tactics such as bandwidth over-provisioning, firewalls, and intrusion prevention system (IPS) devices are no longer sufficient to protect an organization’s networks, applications, and services. VeriSign has successfully defended its global DNS infrastructure against DDoS and other attacks for more than 10 years and has maintained 99.99 percent availability of its critical infrastructure during that time. In addition, VeriSign has maintained 100 percent availability of its .net and .com infrastructure and resolves more than 50 billion DNS transactions per day. Drawing on this success and hands-on engagements with customers in a range of industries, VeriSign has identified a set of best practices that enables organizations to keep pace with DDoS attacks while minimizing impact on business operations. This paper describes these practices.

Openfiler and XenServer Reconnection Issues PDF Print E-mail

If you are trying to use OpenFiler 2.3 as a storage repository for Citrix XenServer, you may run into a reconnection issue when you reboot OpenFiler.  Namely, you cannot reconnect your iSCSI data storage.

The problem has to do with OpenFiler scanning the volume created by XenServer in the iSCSI Volume Group.

How to fix?  This worked for me:

1. Comment this out in /etc/rc.sysinit:333-337

Code:

#       if [ -x /sbin/lvm.static ]; then
#               if /sbin/lvm.static vgscan --mknodes --ignorelockingfailure > /dev/null 2>&1 ; then
#                       action $"Setting up Logical Volume Management:" /sbin/lvm.static 
# vgchange -a y --ignorelockingfailure # fi # fi

2. Change in /etc/lvm/lvm.conf:53

Code:

filter = [ "r|/dev/dm-*|", "r|/dev/VG_XenStorage*|", "r|/dev/sr/iscsi|", "a/.*/" ]

3.  Turn off AOE (ATA over Ethernet)

chkconfig aoe off



4. Restart and you should be good to go.
