Port Redirection

I had a need to access remote UDP ports that were not open through my VPN connection. I thought no problem I will just configure my ssh connection to tunnel those ports! I quickly found that traditional SSH port forwarding does not support UDP. So I had to find a work around.

In order to tunnel UDP requests through SSH you need to find unused TCP ports on your local and remote machines and configure them to forward requests to the UDP ports that you need to access. This can be accomplished using socat or nc on *NIX machines.

Found a neat utility to ease the process of network port forwarding in Windows.

Stupidity Amazes Me!!!!

I was watching the news and saw the recent peaceful protesters bring firearms to rallies protesting Obama and the Second Amendment and I was amazed at the stupidity of it. How stupid are these people, giving politicians the political fodder they need to use against them?
That is about as smart as going to a bar next to a police station, stumbling back to your car, blowing your horn and driving off. Yes, you can go to a bar, yes you can blow your car horn and yes you can drive home. But it is bringing unneeded attention to yourself and begging for a police officer to pull you over. People like those I saw on TV are like that, they would go in to the bar, drink water, fake stumble out to the car, flip the cops off and drive off. They are sober, so everything is legal and when the cop rightfully pulls them over, they are going to yell that their rights have been violated and are being targeted by the police. Then you get things like ridiculous alcohol level laws and sobriety traffic checkpoints all because some dummies screwed it up for the rest of us (No I don't think that is how blood alcohol tests and sobriety checkpoints were started I am just using a parable here).
I support the 2nd Amendment, probably more than the average citizen, but I would not do anything as stupid as publicly carrying my legal weapon to a protest against the president, basically asking people to take my rights from me. I almost wonder if opponents of the 2nd Amendment paid some of these individuals to show up at these rallies to look stupid; one of the guys with the M4/AR-15 strapped on his back did not look comfortable at all with the weapon, just stupid no matter what and it hurts the rest of us. I know people are saying that is just proof that stupid people are allowed to own firearms and they should be confiscated, but we can not throw away what was given to us by our founding fathers because of a few idiots. If we do then what stops us from losing even more for our own "protection". Likke automobiles for example. I could legally buy a dump truck and drive it full speed through the middle of a crowded stadium during the Alabama vs Auburn or Ohio State vs. Michigan game and chances are I would hurt a lot more people than I could ever get with any semi-automatic firearm. More people are injured by stupid, careless drivers every year than ever get wounded by a firearm.  A true example is where a construction company owner, wielded steel around his bulldozer and took it on a destructive killing spree through the middle of a down town in the Midwest. Yes this has actually happened.  I can still buy a bulldozer of my own though.

Thoughts on Movie Advertisement

While watching TV tonight every station aired commercials for the new Brad Pitt movie every 30 minutes it seemed. The big line is

"We are interested in one thing, Killing Nazis"

I find this kind of funny, it doesn't disturb me at all, they were the enemy of the US during that time period. I saw the original "Inglorious Bastards" when I was about 9 or 10 on HBO (that is the first movie I remember having nudity in it from my youth, it made a lasting impression to say the least) . What does surprise me though, although it shouldn't, is where are all the do gooders who normally come out to say "you can't say that, you are going to offend the Germans", you know, the kind of people Hollywood is made up of. The kind of people who say eating meat is murder to animals.

What would happen if that same line was used every hour advertising for other movies about our wars against the Japanese, Koreans, Chinese, British, Iraqis, American Indians, Philippines, etc. (you name them and chances are high that the US Army has done away with a group of them, we are quite good at that, after all killing is the job of the military whether we acknowledge it or not. Any soldier active or not, remembers standing on the parade field and screaming at the top of their lungs "WHAT MAKE THE GRASS GROW GREEN, ........ THE BLOOD, THE BLOOD MAKES THE GRASS GROW GREEN". That is when the realization of you job duty as a soldier comes to the forefront)

I am just curious as to what would happen if any other former or current enemy of the US was targeted in this manner. Where are the people saying consider the feelings of the Germans, many people living in the US are former German Nazis, they were being loyal to their country at the time. I wonder what they think as they see that commercial hourly and remember their dead brothers who were justifiably slain by the American War machine.  If we can bring up those wounds to the Germans, why is it not ok to show video clips of the attack on the twin towers every hour to make us remember current events and why we need a strong defense and that their are very powerful forces out there who wish death and destruction upon us.

Since there are American Nazis, I do not agree with them by the way, and I think they are a sad ridiculous group (the original Nazis were for national socialism by the way, remind you of  some of our current politicians?), why can we say "We are in the business of killing Nazis" but if someone said the same thing and substituted another group, say Muslims, they would be chastised and branded hate mongers? All Muslims do not wish death and destruction on us, all Nazis did not wish it upon us either. I know an old man who was a member of the former Hitler youth, he says he didn't understand at that time what it was really about, but that he was wanting to defend those around him and be patriotic to his country, not necessarily kill people. He said most of those around him felt the same way he did, it was the radicals that you had to watch out for. Sounds familiar to current events doesn't it? But yet it is OK to label them and wish death upon them.

I am just wondering if anyone else finds it odd. Personally it doesn't bother me, I was just noticing how it seemed unfair for us not to be able to say we are in the business of killing our current enemies when it is okay to glorify our past victories of killing Nazis. As a closing statement I will say that when I joined the U.S. Army at 17 years old, I like every other soldier, swore an Oath to Protect the Constitution of the United States of America from ALL enemies foreign and domestic, so any enemy of the US and its Constitution (yes even domestic politicians) should be fair game. Things are different now then they were in the 1700's; unfortunately we can't tar and feather them anymore and get away with it; the only effective weapon we currently have against those domestic enemies of the Constitution is our vote, so in the next voting year I am going to vote against any incumbent politician (Republican or Democrat) who has voted against what was laid out by our founding fathers when they laid out our Constitution. I am scared I am in a losing battle for the first time in my life. Get on the "We are in the business of Killing Socialism" band wagon and stick up for what so many of our forefathers died for.

Email Attachments - Consider Before You Embed!

I recently received an email from someone in a storage related distribution list. At the bottom of the email it has this bitmap image embedded in the email (I have saved it as a png file to compress it without losing any of its original quality and save space).

The only thing that made me notice it was that the email showed that it had an attachment, the only attachment was this image. I then started thinking, why use an image to say this, that takes up unnecessary space. I looked at the email properties and found that the size of this email was 54 KB. Not too bad, but I looked at another much longer email that had no embedded images or files and saw that the average was 7 KB. I saved the attachment out and found that his embedded image was 28 KB by itself. There again, not a huge amount. Then I looked at how many people were on this distribution list (all of the recipients are on the same Exchange server) and found that there were roughly 2,500 people that received that email and attachment.With that one 28 KB attachment it has consumed around 70 MB of storage.
             28 KB * 2500 =  70,000Kb (68.4 MB)
Still not a whole lot. But, considering that I could go back and see that this same person has sent over 25 emails to this distribution list you now have 1.67 GB of storage consumed it is starting to look like a lot of wasted storage.
             68.4 * 25 =  1,708.98 MB (1.67 GB)
 
I know that I have seen this same attachment on a lot of emails not only from this poster but from others as well. If only 4 other users have this same embedded attachment and they send 10 emails each then they have consumed around 2.67 GB of storage for their attachment only. This does not include any actual useful data.
            4 * 28 KB = 112 KB
            10 * 112 KB = 1,120 KB
            1120 KB * 2500 = 2,800,000 KB (2,734.375 MB) or (2.67 GB)
If over a 6 month period these same 4 users send an additional 2500 emails  that has 10 people carbon copied then they have consumed yet another 2.67 GB bringing them up to 5.34 GB of storage! To put this into perspective an MP3 version of AC/DC's song Back in Black takes roughly 3.95MB of storage. You could store 1,367 copies of that song in the same amount of storage used for the attachment in this email.That is over 136 individual music CDs. If a storage administrator found a single user on this same Local Area Network storing 136 CDs on corporate owned storage it would be grounds for dismissal.

What makes this stand out to me is that this is a distribution for Storage Professionals, people who should understand the implications of extra data embedded into an email, I could understand if these were normal End Users, but not those whose job it is to minimize the amount of money spent on storing data. Maybe they should change their logo to a text version that states:

Consider Your Storage: Only include attachments when absolutely necessary to get your point across! And if you are going to print this email delete it from your inbox.

NYTIMES : New Poll Finds Growing Unease on Health Plan

I wrote about statistics before but, this ending to an article refusing to say anything negative about the president says it all.I which finding the white house will be using.

In one finding, 75 percent of respondents said they were concerned that the cost of their own health care would eventually go up if the government did not create a system of providing health care for all Americans. But in another finding, 77 percent said they were concerned that the cost of health care would go up if the government did create such a system.

Massachusetts Says Encrypt It All!

A law that takes effect in Jan 2010 reads like this

• "All persons that own, license, store or maintain personal information about a resident of the Commonwealth," which presumably means any business anywhere that does business with Massachusetts residents
• Paper as well as electronic records
• Secure user user authentication protocols
• Secure access control measures
• Encryption on all wireless networks linked to personal information repositories
• Monitoring and encryption for all portable devices with personal information
• Firewall protection for any database containing PII
• System security software must be installed and kept up to date
• Education and training is also required

It is pretty restrictive yet it is still open for interpretation and leaves a lot of leverage for prosecutors to go after a company that they want to bring down. If you have ever been involved with the PIN or SAS70 type audits then you know how these rules can be interpreted differently by any governing body. Bottom line is this is going to be VERY costly to many organizations. It is not a bad thing to a degree, but it will be costly and probably abused by law enforcement officials who do not understand how computer technologies actually work.

CBS press Sotomayor about her 2ND Ammendment views and she refuses to answer

President Obama's first nominee to the high court did previously say that she believed Americans do not currently enjoy a fundamental right to bear arms, which echoes her two previous rulings on the topic as an appeals court judge. But now she refused to elaborate on her views about firearms regulations and the Second Amendment, saying she would "make no prejudgments" about future firearms-related cases.

New York Lawmakers

New York House Assembly actually has an annual "Anti-Gun Day" for enacting new laws in the state. This takes place every April 29th.

One of the crazy things being proposed for the next year is a mandate to modify handguns to make it impossible to be operated by children. It would require a 10lb trigger pull and require multiple motions in order to fire the weapon. Another requirement would be to require firearm retailers to carry insurance to cover any criminal acts committed after the sale of a firearm.

Sending email with attachments on UNIX systems

Sending email with attachments on UNIX systems
All of the below examples use the following shell variables. I use MIME type application/octet-stream just as an example. Actual type used will vary depending upon attachment file type. Remember, these are simple examples of the different tools available.

TXTFILE=/tmp/textfile  # A text message with a simple preface message
ATTFILE=/tmp/binary_file # File to be attached and generally requiring encoding
SUBJECT="Your attachment" # Change as needed
MAILTO=user@where.ever  # Ditto

uuencode – This is the original method to send encoded text within a message. It is not an attachment as we think of them today but is still used enough to warrant putting it here. 
uuencode $ATTFILE $ATTFILE | mail -s "$SUBJECT" $MAILTO
(uuencode $FILE1 $FILE1; uuencode $FILE2 $FILE2) | mail -s "$SUBJECT" $MAILTO
 

simple shell commands – For a very simple text (plain or html) attachment with just one file: 
echo "From: $LOGNAME\nTo: $MAILTO\nSubject: $SUBJECT\n\
Mime-Version: 1.0\nContent-Type: text/plain\n" > /tmp/file
cat $TXTFILE >> /tmp/file

VMWare VSphere 4i SSH

I haven't verified this, but I found this snippet on a web site earlier today
SSH in vSphere 4i
tweetmeme_url = 'http://www.itstuff.ca/2009/06/ssh-in-vsphere-4i.html';
To enable SSH in vSphere 4i we should do the following steps (similar as esx 3i):
1. First, press Alt + f1 then type “unsupported” and press enter.
2. At the prompt for password, provide the credentials, previously configured, and we will be able to log in to the service console.
3. Do a vi /etc/inetd.conf and look for #ssh. Remove the # and save the file after this.
4. Go to /sbin, and run this command ./services.sh restart

Now, we will have SSH enabled.

Gran Torino

It is official, Clint Eastwood has made two of the best films ever made.
1. The Outlaw Josey Wales
2. Gran Torino

Both movies are a testament to human behavior and how it is molded by tragedy, warfare, ethnic/cultural differences and trust in people that they thought they would never befriend. An entire thesis on social behavior could be written on either movie.

Both movies show an over the top white guy who everyone misjudges on the surface, who in the end, shows that everyone was wrong about him, he is hard to survive in the only way he knows, by the sword. Clint Eastwood has a way of finding stories that show the backbone of America and how things should be. Gran Torino is fabulous and Clint Eastwood is one of the only actors who could have pulled it off without the media blasting him.

Verizon Speeds are so wacky

I don't understand why sometimes I will get around 160Kbps download speeds from Verizon and then I get speeds like this. If I could consistently get these speeds I wouldn't complain about my access.



The connection speeds above are with a cellular direct connect Wilson amplifier. The only problem is the direct connect is subject to "interference" from other providers and occasionally will try to put me on the AT&T broadband and I will lose the connection all together. The speed posted below is with a repeater type amplifier, that is slower, but usually a little more stable. It is still faster than an ISDN line though.



I think I am finally going to break down and get the parabolic grid antenna that I keep talking about.

H.R. 197-- the "National Right-to-Carry Reciprocity Act."

H.R. 197 has been introduced that is a positive step forward to the rights of a citizen to travel with the protection they are granted by the constitution. The bill has 127 co-sponsors in the House. Not surprisingly all of the southern states are sponsoring the bill, but to my surprise the bill is also co-sponsored by Representatives from PA, NJ, IL, CA, IN, MI, ME, and OH.  Keep in mind that there are 435 members of the House of Representatives and not all representatives of each state are in support of the bill. This means that less than half of the House has agreed to support the bill and no major action has been taken on it since 2/9/09. Similar bills in the Senate are S.371, S.845 both have 22 co-sponsors and the latest action on them were on 4/21/09.

This bill would allow any person with a valid carry permit or license issued by a state, to carry a concealed firearm in any other state if the permit holder meets certain criteria. In states that issue permits, a state's laws governing where concealed firearms may be carried would apply within its borders. In states that do not issue carry permits, a federal standard would apply. The bill would not create a federal licensing system; it would simply require the states to recognize each other's carry permits, just as they recognize drivers' licenses.

Lloyds Bank hit by Obama tax purge

In a struggling economy all we need is for foriegn banking establishments to be scared to accept clients with ties to the United States. The following excerpts from the article are the highlights from the UK Telegraph article:

This week American private client account-holders at Lloyds's received letters informing them of an "important change in policy regarding clients who are resident, domiciled or linked to the United States by property or asset holdings". They were told the bank had "no choice" but to "cease acting as your investment manager."

The Sunday Telegraph reported that British banks and stockbrokers were threatening to close down accounts held by American citizens due to concerns over new international tax proposals could make it too expensive for them to service the clients.

APCIMS, the trade body whose members manage £400bn of Britain's wealth and employ 25,000 people, sent a letter to the US Treasury's Internal Revenue Service (IRS) complaining that the "unfair'' proposals represent "no benefit but . . . significant cost'' to its members.

Joke???

From a June 3, 2009 NY Times interview
“We have a joke around the White House,” the president said. “We’re just going to keep on telling the truth until it stops working — and nowhere is truth-telling more important than the Middle East.”

Was this supposed to be funny? What do you do when it doesn't work? Lie? That sure seems to be the recipe for the attacks on gun ownership, one of the biggest examples of late are the reports on Mexican gun violence being a by product of US gun runners has been a lie. The numbers were directly disputed by reports from the FBI and those published by the Mexican authorities as well. I am not a fan of Bush's last term or his blatant disregard for the Constitiution, but if he would have made this statement the press would have blasted him and labeled him a liar; it would have been headlines across the country. Instead they use this to promote him as an honest President. Time is yet to tell; personally I distrust 99% of all politicians.

Verizon Speeds Again

 I can not determine why my Verizon connection speeds are so good at times but at other times they suck. Today was another good day.


I am surprised at how fast the upload speeds are. I still want to try the Parabolic Grid Antenna.

Virtualization for Dummies

In my job I have to read a lot of Vendor biased documentation, and occaisionally I run across a document that is actually useful for more than just understanding a certain vendors offering and can be applied across the board.

This article on virtualization, actually describes it pretty well and discusses why it is important. Keep in mind it does have a slant toward AMD processors and SUN, but nevertheless a good read of how different types of virtualization works specifically around x86 hardware. This document is mainly geared toward the SMB market and does not address the high end hardware virtualization methods of IBM, HP or even SUN. It is written by the authors of the "For Dummies" series of books so it is fairly easy to read, even if some of the content will make your head swim.

VMWare ESX fails to mount ISO image

I was installing the newest OpenSolaris on VMware ESX 3.5 tonight and I wanted to mounted to verify my disk image prior to the install so I thought simple; mount the ISO and browse the file system and that will show everything is ok. I created the mount point and ran the Linux mount commands and got an IOCTL error.

[root@x4100 x4100:storage1]# mkdir /tmp/isoimage
[root@x4100 x4100:storage1]# mount -o loop /vmfs/volumes/x4100\:storage1/OpenSolaris.iso /tmp/isoimage/


ioctl: LOOP_SET_FD: Invalid argument
 
After a lot of research I found this article. That explains that if you try to mount an ISO image from a VMFS file system you get the aforementioned error. The problem I had is the ISO I was trying to mount is on a VMFS filesystem and the mount command only works for images residing on a Linux filesystem, and vmfs doesn't count as a Linux filesystem. 

I moved the ISO to the /tmp filesystem and everthing worked as expected.

[root@x4100 x4100:storage1]# mv OpenSolaris.iso /tmp
[root@x4100 x4100:storage1]# mount -t iso9660 -o loop /tmp/OpenSolaris.iso /tmp/isoimage
root@x4100 x4100:storage1]# cd /tmp/isoimage/

[root@x4100 isoimage]# ls
bin dev jack pkg.zlib proc root solarismisc.zlib system
boot devices mnt platform reconfigure save solaris.zlib tmp
[root@x4100 isoimage]# cd ..
[root@x4100 tmp]# umount /tmp/isoimage/
