Sending E-mail via Telnet

How to:
  • Use Telnet to connect to the SMTP server.
  • Send commands to the server to build the envelope and send a message or more
The functionality is quite similar to how a real E-mail clinet interacts with a SMTP server.

Step 1

In a Windows DOS or Command prompt, and enter:

C:\WINDOWS>telnet smtp.domain.com 25

This will open a Telnet window and connect to the SMTP server. The server responds with:

220 server5.domain.com -- Server ESMTP (SMTP Server)

The above message will be different for each server, but you should definitely get '220' response. It is an indication that the server is ready for your request.

Step 2

Now the server expects you to identify yourself. Using your computer's hostname, enter the following to identify yourself to the server. My hostname is "cronos" so I will use that:

helo cronos

Note that it is 'helo' and not 'hello'. The commands are not case-sensitive, so you can also say HeLo or HELO or hELo. The server replies:

250 server5.domain.com OK, [192.168.10.20].

This initiates the handshake between the server and the client. The server returns a '250' message and a hello message and your client IP address.

Step 3

Next give the server your E-mail address. Most SMTP servers require that your e-mail address belong to the same domain as the server. For example, our domain is 'domain.com' and we will use an E-mail address user@domain.com. Lets tell the SMTP server the E-mail address:

mail from: user@domain.com

'mail from:' is an SMTP command. Note that there is a space between 'mail' and 'from', followed by a colon (:). The server says:

250 2.5.0 Address Ok.

Step 4

Now we tell the server who we want to send the e-mail to. Let's send an E-mail to info@domain.com:

rcpt to: info@domain.com

There are no restrictions here. You can enter any e-mail address. If there is some problem with the recipient-address, your mail will bounce, but for now, the server doesn't complain. It will say:


250 2.1.5 info@domain.com OK.

Step 5

We have given the server your E-mail address, and the recipient's E-mail address, so now we can go ahead and type the e-mail. You have to do that with the data command:

data

The server asks you to go ahead with your E-mail:

354 Enter mail, end with a single "."

Step 6

Now type your E-mail, like this:

This is a test e-mail.
Remember to type it all right. Backspace key doesn't work in Windows
Telnet, though it does in Linux. If you make a mistake, try pressing
CTRL-h.

When you finish your e-mail, press [ENTER], then a '.', and again an [ENTER]. This tells the server that you have finished the E-mail, and it can send it. It will say:

250 2.5.0 Ok, envelope id 0M0H00081FQRNP10@server5.domain.com

Your mail was sent!

Step 7

Now you can either send another mail, or disconnect from the server. If you want to send another mail, you will repeat the 'rcpt to:' and 'data' commands. There is no need for 'helo' and 'mail from:', because the server already knows who you are. If you want to disconnect, just say 'quit':

quit

The server will reply:

221 2.3.0 Bye received. Goodbye.

and you will lose connection with the server.

The NEW Safer Archive Drive

I take a ton of pictures. I have a nice RAID1 array inside my main editing PC and archive old images to DVD as well as external drives. Recently (see previous post) had a close call where one of my DVD backups failed and when I went to my archive external disk, it failed as well. It was a RAID0 array and even if I pulled the drives from the failed enclosure, I would have no hope of restoring the data since it was striped across two drives.


Anyway, I solved that problem with a new power supply... thank goodness. So time to pay more attention and pay more for a more reliable external storage solution. I ultimately want to get a good RAID5 or even RAID10 solution but they are expensive. For now, I would settle for a mirrored solution.


I decided to go with the newly released, Western Digital MyBook Studio Edition II 2TB Quad Interface. It comes with a dual drive (1TB each) setup in RAID0 formatted for HFS+ (Mac OS-X) but I would be using it in Windows Vista Ultimate x64 and in RAID1.

The things that made up my decision were the eSATA interface, the excellent design, the ease of service if a drive fails and the capacity and RAID1. Price is a little high but B&H has them for $464.00.


http://www.wdc.com/en/products/products.asp?driveid=410


Here are some benchmarks using FireWire 400 and eSATA connections. My PC isa custom built Asus Striker Extremewith Intel QX6700 and 4GB RAM. The eSATA is a Silicon Image chipset built into the MoBo.

FW400





eSATA

My External Drive Woes

Amongst many external drives in my collection, I have a LaCie Big Disk Extreme 500gb Triple Interface which all of a sudden decided to die on me.
The front blue light began to flicker dimly and I thought initially that it was simply Disk Activity/Access.. but it was not. I would hear the attempt to start the drives inside but it would end in 1/2 of a second.
Googled and Googled and everything pointed to bad and poor service, workmanship, issues left and right. Great, I was hosed :-(
But some of the articles pointed to some options, namely that my power supply could be bad. The model number for the power supply that came with my unit was 706479 or ACML-51

I went out to B&H Photo and purchased a spare Power Supply. I bought an updated model 710199 which is clearly labeled as non usable by LaCie on my model drive. But I decided to go ahead anyway... I was desperate. The original supply puts out 26W and the new one 34

I was very glad to see my drive power up again and show up as a drive on my system. I quickly moved off all my critical images off this drive.
Little did I know this was a dual drive, RAID0 array with two Western Digital 250GB drives inside. If there is a failure of either drive, all your data is hosed. This setup is good for high speed FW800 video editing or scratch space for NON-CRITICAL stuff... NOT for a backup device. I plan to dismantle the unit and use the drives in a new RAID1 enclosure for archiving.

Dell Inspiron XPS Laptop very slow - Solved!



For the last few days, I have been struggling with my normally super fast Dell Inspiron XPS Generation 1 laptop behaving as if it had molasses running through its veins.

I initially of course thought it may have been a virus that somehow made it through Norton AV. Nope!

Then I figured it may have been fragmentation. I defragged the drive (which had been neglected for some time) and for a moment it seemed to have helped a bit... Nope!

Okay, deeper we go. I started to figure out a pattern. ALL GRAPHICS ops were severely affected. However, it was only 2D and video (Flash, QuickTime, WMV, MPG, etc.) and no matter what was playing... Windows Media Player (I upgraded to 11 Beta, Nada) QuickTime, IE Embedded video, Video LAN, etc. etc.

I uninstalled codecs, cleaned up registry settings, ran a media cleaner... Nope!

Next up, Video Drivers. My lappy has an ATI Mobility Radeon 9800 with 256MB RAM. Interestingly, all 3D graphics were fine... which pointed to a main CPU issue, not a GPU problem.

Upgraded the video drivers to the latest ATI Catalyst set.. No fix.

Reverted back to the Dell native drivers (they have not been updated for some time by Dell) and still no fix. I then used a little tool called

DH Driver Cleaner Professional Edition
http://www.drivercleaner.net

which helps get a clean start if you feel one of the 10,000 files installed with a modern video card is corrupt or something.

STILL NO FIX! ( I promise there is a solution at the end )

Now it was time to uninstall stuff. I started with Add and Remove Programs... tool and got rid of stuff I wasn't using. I got rid of a lot of add on toys and little tools and some major HD hogs that I wasn't using (like 3DSMax, AutoCad, Adobe Premiere Pro 2.0, After Effects Pro 7) Nothing Fixed!

Man, I was frustrated. I ran a complete Norton AV scan... nothing

I ran a complete Spyware scan (Adware, Microsoft antispyware beta, etc.) nothing...

Time to hit Google. This yielded one answer after another, one idea after another, none of which made any sense to my because they all had different solutions to different slowdowns. Mine was consistently slow under anything that stressed the video especially. The purely CPU apps did not show much of a problem other than being slower. Video was plain and simple : UNUSABLE.

But, I got to thinking about overheating. My older Dell Inspirons all had overheating problems. I didn't think my new XPS had a problem because I had the latest BIOS which specifically fixed an overheating problem and a fan speed issue.

Further digging in the Dell Inspiron forums revealed a possible problem with clogged radiators (the heating pipes for the CPU and GPU end up on large radiators that sit in front of blowers that force air though them from below the machine and through the radiators and out the back of the machine)




Once I cracked open the fans and pulled them, I was AMAZED at how badly (and totally) blocked the radiators were... no wonder the fans were ALWAYS ON. I quickly vacuumed the dust screen off, blew compressed air throughout to remove any leftover residue. Made sure the path was completely clear through the radiators.



Replaced the fans, closed up and started the beast once again. I reset the BIOS, and went into Windows. I was quickly reminded how quiet it can be in my office when the fans are OFF :-) I quickly logged in and ran through some tests... ALL WAS BACK IN NORMAL RANGES. My CPU and GPU and HD and Chipset temperatures were almost shaved in half... AMAZING!

The video was back up to FULL SPEED. If your Inspiron XPS is acting funny, check the vents, the fans, any radiators, etc. Likely, it is a temp problem.

The Pentium 4 HT has a built in self protection mechanism which will gracefully slow down the chip as the temperature rises instead of just shutting itself off (as in the past). However, it is tough to accept because all the CPU speed reporting tools (including windows 'My Computer... | Properties" itself) do NOT report that the CPU has throttled down.

Wayfinding Is Not Signage

Signage plays an important part of wayfinding -- but there's more

By John Muhlhausen, Signs of the Times magazine

Even though signage plays an important role in wayfinding, the
process doesn't rely exclusively on signs.

The term "wayfinding" was first used in 1960 by architect Kevin
Lynch in The Image of the City, where he referred to maps,
street numbers, directional signs and other elements as "way-finding"
devices. This narrow description may explain the current
misunderstanding that wayfinding is essentially the same as
"signage."

The two terms are not synonymous. Signmakers deal with designing,
fabricating and installing signs. However, wayfinding used to
navigate unfamiliar environments, doesn't rely exclusively on signs.

This distinction gained acceptance in the early '70s when
researchers discovered that, to understand how people find their way,
they first need to understand the underlying process. Architect and
environmental psychologist Romedi Passini articulated spatial
problem-solving in his books, Wayfinding in Architecture and
Wayfinding, People, Signs and Architecture, which he
co-authored with wayfinding planner Paul Arthur.

Passini and Arthur described wayfinding as a two-stage process
during which people must solve a wide variety of problems in
architectural and urban spaces that involve both "decision making"
(formulating an action plan) and "decision executing" (implementing
the plan).

People who find themselves in unfamiliar environments need to know
where they actually are in the complex, the layout of the complex,
and the location of their destination in order to formulate their
action plans. En route to their chosen destinations, people are
helped or hindered prior to their visit, the building's architecture
and signage. The physical environment, including positive effect in
how users perceive the wayfinding system--if it seems easy to use or
not.

Faulty sign design can cause navigation problems in unfamiliar
environments. Some signs lack "conspicuity," or visibility, because
lettering lacks legibility when viewed from a distance. Others
contain inaccurate, ambiguous or unfamiliar messages; many are
obscured by obstructions or contain reflective surfaces, which hinder
comprehension. Consequently, many people don't read signs--often it's
easier to ask for directions.

Because wayfinding problems aren't confined to signs alone, they
typically can't be solved by adding more signs. Instead, such
problems can be unraveled by designing an environment that identifies
logical traffic patterns that enable people to move easily from one
spot to another without confusion. Signs cannot be a panacea for poor
architecture and illogical space planning.

Four elements

Wayfinding needs are best resolved during initial planning stages
through a collaborative effort by all design
professionals--architects, designers and signmakers--to address a
project's total environmental communication. The primary generator of
environmental communication, architecture delineates spatial
organization, destination zones and information sequencing--factors
that spell wayfinding's success or failure. Effective architectural
wayfinding clues, provided by roads, building layouts, corridors and
lighting, furnish cognitive maps that allow people to quickly grasp
the environment. To furnish architectural clues:

  • Clearly identify arrival points.
  • Provide convenient parking and accessible walkways located
    adjacent to each public entry.
  • Locate information desks within each public entry visible from
    the front door.
  • Place elevator lobbies so they can be seen upon entering the
    building.
  • Use consistent lighting, floor coverings and architectural
    finishes in primary public corridor systems.
  • Situate memorable landmarks along corridors and at key
    decision points.
  • Design public waiting areas that are visually open to
    corridors.
  • Distinguish public from non-public corridors by using varied
    finishes, colors and lighting
  • Harmonize floor numbers between connecting buildings.

Graphic communication

Graphics, such as signs, color coding, maps, banners, brochures
and Websites, provide orientation, direction, identification and
regulatory information. To achieve effective graphic communication:


  • Standardize names for all buildings, services and
    destinations, and display them consistently on all graphics
    applications.
  • Use easily understood "plain" language.
  • Size messages and signs appropriately for viewing
    distances.
  • Select letterforms and color combinations that comply with
    Americans with Disabilities Act (ADA) Accessibility Guidelines
    (see
    New Face to ADA).
  • Furnish generous spacing between letters, words and message
    lines.
  • Provide standardized "you are here" maps of the project that
    include an overall map of the complex and more detailed maps of
    specific areas.
  • Train attendants to mark individualized paths on hand-held
    maps for lost or disoriented visitors.
  • Place maps at all parking exits, building entrances and major
    interior decision points.
  • Orient maps with building layouts, such as denoting on maps
    that "up is ahead."
  • Establish consistency in sign placements and graphics
    layouts.
  • Code areas by using color and memorable graphics.
  • Use established pictographs with words to facilitate
    comprehension of written messages.
  • Establish a floor numbering system that relates to a
    building's main entry and indicate on directories which floors are
    above and below grade.

Audible communication

Audible communication, as interpreted through verbal instructions,
PA systems, elevator chimes and water fountains, plays an important
role in wayfinding. Recognizing that 50% of the American population
is functionally illiterate (according to a recent study published by
the U.S. Department of Education) and that another 15% possess other
perceptual or cognitive impairments, audible communication fills an
important role in any wayfinding solution. To establish effective
audible communication:

  • Install audible sounds at signaled intersections to indicate
    safe times to cross the street.
  • At all public entries and information desks, provide
    attendants trained as professional greeters who are thoroughly
    familiar with the facility.
  • Furnish self-help telephones at all information desks.
  • Provide patient-transport personnel whose purpose is to guide
    visitors to their destinations.
  • Standardize names for all buildings, services and
    destinations, and use them consistently in verbal
    communication.
  • Equip elevators with audible chimes.
  • Position audible landmarks, such as water fountains, at
    waiting areas.
  • Employ audible signs to help locate information desks,
    elevators, rest rooms and other key destinations.

Tactile communication

Tactile communication, achieved by raised letters, Braille,
knurled door knobs and textured floor coverings assists all
visitors, not only the disabled. To incorporate tactual devices into
a wayfinding system:

  • Establish "shorelines" and "trails" between major destinations
    and information areas using materials having differing
    resiliency's, such as concrete and carpet.
  • Install "rumble strips" at the landings of stairs and
    escalators.
  • Furnish knurled door knobs at all non-public doors.
  • Provide a raised star symbol on elevator control panels to
    indicated the ground floor.
  • Supply raised letters and Grade 2 Braille at elevators and on
    signs identifying permanent destinations.
  • Install interactive audio-tactile maps at public entrance
    lobbies.


Consistent clues

Architects, designers and signmakers must work together from the
beginning of a project to create a total environmental statement that
provides consistent clues. So, the next time a client asks for
wayfinding signage. tell them that wayfinding is not signage--it's
more.
