Been a long time

March 10th, 2013

Well have not written or ridden in quite a while  I was notified or a really good deal on  frame and fork combination around Christmas time so I went ahead and pulled the trigger.  A had test rode this frame a half dozen times and it seemed like one of the funnest bikes I had ever ridden.  So here it is.  Just a short shake down ride after putting it together.

Rode with my favorite ridding partner.  She was busy working on projects so was a bit reluctant.

All to soon we are feeling like this!

Sweet!

A good day for a ride with my favorite riding partner.  Like the way the new bike rides will have to see how this works out.  Have not ridden since October hopefully we get on the trails more in the next few months.

Here’s to sweat in your eye

Sending mail using Perl on Windows NET::SMTP

May 11th, 2010

NET:SMTP is a bit limited compared to Mail::Sender  or MIME::Lite.  For simple emails is is nice and simple.  It can also be handy when working on system where it is very difficult to make changes.  In my case I had 15 system with different version of Perl and make changes was difficult at best.

#!/perl/bin -w

use Net::SMTP;

$smtp = Net::SMTP->new( Host => “your.mail.server.com”,
Timeout => 20,
Debug   => 0,
) || die “SMTP failed”;

$smtp->mail(‘my.email@null.com’);     # use the sender’s address here
$smtp->recipient(‘someones.email@null.com’, ‘somebody.else@null.com’, { Notify => [‘FAILURE’,’DELAY’], SkipBad => 1 });   # Good
#        $smtp->to(‘someones.email@null.com’);        # recipient’s address
#        $smtp->to(‘somebody.else@null.com’);        # recipient’s address
$smtp->data();                      # Start the mail

# Send the header.
$smtp->datasend(“Priority: Urgent\n”);
$smtp->datasend(“To: someones.email\@null.com, somebody.else\@null.com\n”);
$smtp->datasend(“From: my.email\@null.com\n”);
$smtp->datasend(“Subject: Windows Perl Test Mail.\n”);
$smtp->datasend(“\n”);

# Send the body.
$smtp->datasend(“Please reply if you recieved this email.  My name is Mud.\n”);
$smtp->dataend();                   # Finish sending the mail
$smtp->quit;                        # Close the SMTP connection

If you call the pl2bat utility on your Perl script helloworld.pl, like this:

    C:\> pl2bat helloworld.pl

it will produce a batch file, helloworld.bat. You can then invoke the script just like this:

    C:\> helloworld
     Hello, World!


You can invoke it on the command line like this:

cat myfile.txtYou can use it with I/O redirection (Windows 2000 SP3 and later) like this:

cat myfile.txt > newfile.txt cat myfile.txt | more

The best approach to use when writing Perl scripts that need to send email and also need to work on both UNIX and Windows systems is to use the Mail::Sender modules

You can install Mail::Sender by running:

  ppm install mail-sender

…at a command prompt. Documentation for using Mail::Sender is available here:

February 11th, 2010

 # format
Searching for disks…done
AVAILABLE DISK SELECTIONS:
0. c0t0d0 <drive not available: formatting>
/sbus@6,0/SUNW,socal@d,10000/sf@0,0/ssd@w210000163787753a,0

Sometimes

# format -Mm
may be helpful as this reports additional messages about what is happening.

Get a list of disks

# format < /dev/null or echo “\n” | format

format non destructive commands
disk, current, defect, verify, save, inquiry

format destructive commands
type, partition, format, repair, label, analyze, backup

formating using another disk
# prtvtoc /dev/rdsk/c0t0d0s2 | fmthard -s – /dev/rdsk/c0t2d0s2

Install boot block
# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c0t2d0s0

A fairly typical layout is

0. /
1.  swap
2. whole disk
3.  /var
4. /data

If the system has has a database locally and there is a need for a bit of extra speed then /data can always be put on the faster part of the disk. Not to many systems swap much anymore since there is the ability to put in as much memory as is needed. Although if needed a seperate filesystem can be created for a swap partition.
0. /data
1. /
2. whole disk
3. /swap
4. /var

Solaris – Compress, Uncompress

September 1st, 2009

Backup to a USB drive

Mount USB drive and check contents

# volrmmount -i rmdisk0; cd /rmdisk/rmdisk0; ls -FC

tar -cf foobar.tar /tmp/dir

jar cf foobar.jar /tmp/dir/*

jar are cool, they do however require the Jave Runtime Engine.  jar’s do not maintain soft links the do follow the soft link and copy the contents. 

compress -v foobar.tar

ends up with foobar.tar.Z

to view compress files use zcat foobar.tar.Z | less

or extract the output in conjunction with tar

zcat foobar.tar.Z | tar xf –

uncompress -v foobar.tar.Z

look at contents with uncompress

uncompress -c foobar.tar.Z | tar xvf –

compress and uncompress with 7za

7za a foobar.7z file1 file2

7za x foobar.7z

gzip -v filename

gunzip filename

gzcat filename to view contents of zip file

use unzip on .jar .zip files

x86 / Linux raid

September 1st, 2009

Note not “hardware” raid cards for pc type machines actually do hardware raid.  Most of the cheaper raid controllers are doing a form of software raid that uses their driver and the system bios.

 At that point it is probably best just to use the OS to do the raid and skip the extra.

 If it states somewhere on the box  (e.g., 3w-xxxx, 3w-9xxx, aacraid, cciss, dac960, dpt_i2o, gdth, ips, megaraid, megaraid2, megaraid_mbox aka megaraid-newgen, mpt*) then there is a good chance that it is true hardware raid.

A couple of good pages

This page has a good list of what is and what is not true hardware raid.

http://linuxmafia.com/faq/Hardware/sata.html

A site that talks about what they are calling fakeraid.

http://linux-ata.org/faq-sata-raid.html

This is a good break down on what is the difference between fakeraid and hardware raid.

http://mark.kolich.com/2008/11/sata-raid-cards-linuxwindows-what-you-should-know-about-fake-raid-cards.html

I have cut and pasted this article below on the off chance this page ever disappears.  I do not do this often but on occasion I put in a link to a quality article then years later go back and it is gone.  Just want to make sure I keep this one.

 .  Be sure to check out Mark’s Blog.  It has quite a bit of real good stuff in it.  I ended up getting lost in there for a bit.  Good Stuff.

SATA RAID Cards (Linux/Windows), What you Should Know About Fake RAID Cards

| 1 TrackBack

I recently had a rude awakening regarding many of today’s RAID cards; come to find out most of today’s RAID controllers are not actually “hardware RAID” cards like you might expect.  A few days ago, I went to Fry’s and picked up a relatively cheap SATA 4-Channel RAID card (SC-SA4R12-S2) by SIIG.  I brought it home, unpacked it, and plugged it into my Linux box.  Everything was working well, except that the raw disks connected to the RAID controller were exposed under /dev:

/dev/sdc
/dev/sdd

I found this strange, because I used the controller’s Option ROM configuration utility to build a RAID-1 volume (a mirror) of the two SATA drives connected to the controller.  Assuming my RAID card drivers were installed, I was expecting to see only one device file for the “virtual RAID array” that I just created (e.g., /dev/cciss/*).  Continue reading to see what’s actually going on.

In my past life with HP-UX, I’ve worked on the HP-UX CISS Smart Array RAID driver.  Using an HP-UX Smart Array RAID solution, or a CCISS Linux Smart Array RAID solution, the OS driver only sees RAID arrays, and uses RAID-specific commands to read/write data.  The individual disks themselves are not actually exposed to the OS.  This is true hardware RAID.  If my new SATA RAID card was actually a true hardware RAID controller, I wouldn’t see both disk device files under /dev.  Instead, I would see a single device file pointing to the mirrored RAID volume.

So what exactly is going on anyways?  I thought my SATA RAID card is actually a hardware RAID card?  Turns out, it’s not.  I dug around looking for answers, and come to find out, many non-enterprise level RAID cards sold today are actually “fakeraid” cardsThese “fakeraid” cards use the OS driver and on-board flash BIOS to provide 100 percent of the RAID capability.  My cheap SATA 4-Channel RAID card (SC-SA4R12-S2) by SIIG is nothing more than a fake; it’s a bare non-RAID SATA controller that relies on the OS driver for most of the RAID operations.  That basically defeats the purpose of buying a hardware RAID card in the first place; the whole point of using a real hardware RAID controller is to offload the RAID processing from the host to the controller itself.

In any event, my SATA 4-Channel RAID card (SC-SA4R12-S2) by SIIG was only $40, so I guess I got what I paid for!  If you suspect your RAID card isn’t a real hardware RAID controller, you can check with Linuxmafia.

If you want to setup a software RAID volume on Linux, read my HOWTO guide.
