November 6th, 2012 11:02 admin View Comments


Riskable writes “Version 1.1 of Gate One (HTML5 terminal emulator/SSH client) was just released (download). New features include security enhancements, major performance improvements, mobile browser support, improved terminal emulation, automatic syntax highlighting of syslog messages, PDFs can now be captured/displayed just like images, Python 3 support, Internet Explorer (10) support, and quite a lot more (full release notes). There’s also a new demo where you can try out vim in your browser, play terminal games (nethack, vitetris, adventure, zangband, battlestar, greed, robotfindskitten, and hangman), surf the web in lynx, and a useful suite of IPv6-enabled network tools (ping, traceroute, nmap, dig, and a domain name checker).” Gate One is dual licensed (AGPLv3/Commercial Licensing); for individuals, it’s pay-as-you-please.

TSA Says Screening Drinks Purchased Inside Airport Terminal Is Nothing New

September 5th, 2012 09:12 admin View Comments


First time accepted submitter lcam writes in with a story about a video that has started a new round of condemnation against the TSA over the testing of drinks. “The video, posted on YouTube on Monday and featured on NBC Nightly News with Brian Williams Tuesday night, has already garnered almost 125,000 hits and nearly 900 comments from angry travelers. It shows two TSA officers swabbing bottles of water, a carton of coconut water and a cup of coffee, among other liquids. ‘Now remember that this is inside the terminal, well beyond the security check and purchased inside the terminal … just people waiting to get on the plane,’ YouTube user danno02 says in the video’s description. ‘My wife and son came back from a coffee shop just around the corner, then we were approached. I asked them what they were doing. One of the TSA ladies said that they were checking for explosive chemicals (as we are drinking them).’ The TSA insisted Tuesday that its policy of checking liquids beyond the security gate has been in place for five years now. TSA agents will randomly patrol the gates using a test strip and dropper containing a non-toxic solution, it said.”

Kmscon Project Seeks To Replace Linux Virtual Terminal

August 21st, 2012 08:37 admin View Comments


An anonymous reader writes “Phoronix reports on the progress of kmscon, David Herrmann’s virtual console project that aims to supersede the Linux kernel’s virtual terminal. kmscon takes advantage of modern Linux features such as kernel mode setting, direct rendering, and udev to provide hardware-accelerated rendering, full internationalization, monitor hot-plugging, and proper multi-seat support. A recent blog post by Herrmann addresses some of his frequently heard questions and criticisms about the kmscon project.”

Terminal Mixup Implicates TSA Agents In LAX Smuggling Plot

April 26th, 2012 04:30 admin View Comments


First time accepted submitter ian_po writes “The U.S. Attorney’s office has filed indictments against 7 people, including two Transportation Security Administration Screeners and two former TSA employees, after federal agents set up several smuggling sting operations. The alleged smuggling scheme was revealed after a suspected drug courier went to Terminal 5, where his flight was departing, instead of going through the Terminal 6 checkpoint his written instructions directed him to. Court documents indicate the plan was to return to Terminal 5 through a secure tunnel after being allowed through security by the accused Screener. The courier was caught with 10 pounds of cocaine at the other checkpoint by a different TSA agent. If convicted, the four TSA employees face a minimum of 10 years in Federal prison.” If ten pounds of anything can get onto a plane by the simple expedient of bribery, please explain again why adult travelers, but not children, must remove their shoes as they stand massed in an unsecured part of a typical U.S. aiport.

Amazon Adds SSH Client to AWS Console

March 9th, 2012 03:02 admin View Comments

aws-logo150x150.pngEarlier this week, Amazon announced that they’d (finally) added an SSH client to the AWS console. Based on the MindTerm Java-based SSH client, the AWS client is looking pretty good.

Now, I said “finally” because I’ve been able to pop open a console from my browser for my Linode instance for quite some time. I was actually surprised that Amazon didn’t have a similar feature.

It’s not particularly onerous having to SSH from a terminal to an EC2 instance if you’re on Mac OS X or Linux, but Windows folks don’t have a default terminal/SSH client. That’s a pretty big segment of Amazon’s business, and I suspect more than a few AWS customers have grumbled about having to download PuTTY to get into their systems.

Using MindTerm

It turns out, MindTerm is a pretty nice little terminal emulator. It takes a couple of steps to launch the first time, because you need to point it to your key to access the EC2 instance (if you have a key, which you should). After that, you can have it launched in a couple of clicks.


Actually, it’s a little more full-featured than Amazon implied in their post. You don’t just get shell access, you can launch multiple shells (without needing Screen or Tmux) and use it to SCP/SFTP files to your EC2 instance as well.


Just go to the Plugins menu of MindTerm and choose SFTP or SCP file transfer. Then you get a simple dialog to transfer files up to your EC2 instance, no typing required.

If you’re running a job in the main terminal window and want a second shell to do something else, go to File -> Clone Terminal or New Terminal.


It looks like you can also use MindTerm to set up an SSH tunnel to your EC2 instance as well.

Overall, I’ve been pleasantly surprised by how snappy MindTerm is and how full-featured it is. If you’re using AWS and need to SSH into your EC2 sessions, give it a try next time.

Data Breach Flaw Found In Gnome-terminal, Xfce Terminal and Terminator

March 8th, 2012 03:50 admin View Comments


suso writes “A design flaw in the VTE library was published this week. The VTE library provides the terminal widget and manages the scrollback buffer in many popular terminal emulators including gnome-terminal, xfce4-terminal, terminator and guake. Due to this flaw, your scrollback buffer ends up on your /tmp filesystem over time and can be viewed by anyone who gets ahold of your hard drive. Including data passed back through an SSH connection. A demonstration video was also made to make the problem more obvious. Anyone using these terminals or others based on libVTE should be aware of this issue as it even writes data passed back through an SSH connection to your local disk. Instructions are also included for how to properly deal with the leaked data on your hard drive. You are either encouraged to switch terminals and/or start using tmpfs for your /tmp partition until the library is fixed.”

Gate One Brings Text-mode Surfing To the Web, Quake-Style

March 6th, 2012 03:47 admin View Comments


Riskable writes “As a follow-up to my previous Slashdot story, Gate One is now out of beta. Packages can be downloaded here. There’s also a live demo: press the ESC key on this page to have a terminal running lynx drop into view, Quake-style! I’ve also posted a video overview and the documentation can be found here. Some pertinent changes since the beta: Added the ability display images inline within terminals, key-based SSH authentication, a WebSockets authentication API (for secure embedding), dramatically improved terminal emulation, an overhauled bookmark manager, support for international keyboard layouts, and a web-based log viewer that lets you export logs to self-contained HTML playback files.”

I Remember IRMA: Reflections on Terminal Emulation Through the Ages

November 2nd, 2011 11:00 admin View Comments

irma-150.pngFor those of you that cut your teeth on graphical OSs and have never had to use a command-line terminal emulator, this article isn’t for you. There is no Flash here, no OCD multi-tasking, cutting-and-pasting from one window to another. If the term ‘command line’ reminds you more of the movie Tron than of something you actually use everyday, then perhaps you won’t find much joy from reading the following post.

But for the rest of us that grew up when PC DOS first came into corporations and when mainframe programmers walked among us, you might enjoy this trip down memory lane.

The memories were trigged by a press release from Attachmate, which is now probably the largest software vendor of things that you don’t really care to try or buy, including probably the leading commercial vendor of Reflection, a terminal emulator. For those of you that are still reading, this is a product that allows you to connect to a command-line console (such as Terminal in Mac OS or Windows HyperTerminal).

Back in this Jurassic era, we had big CRT-terminals that connected to our mainframes with a variety of other boxes, using coaxial cabling. These things displayed 80 characters across text in a single color, and that color was usually green (hence the name green-screen terminals). They could be found on many corporate desktops and looked like this:

When PCs came into businesses, one of their first uses was to stick a card inside them and run 3270 emulation software so they could talk to the mainframes and be used as terminals. This was a semi-big deal, because it meant that you didn’t need to have two devices sitting on your desktop: the 3270 terminal and the PC. Now we have multiple devices on our desktop (tablets, smart phones) and multiple monitors, so I am not sure this is progress. But I digress.

IBM even made for some time a 3270 PC (the model 5271) that combined the two together. It had its own plug-in cards and special keyboard with two rows of function keys as you can see here in the photo.

Starting in the late 1980s, the mainframe cabling was replaced with local area networks of PCs. These were connected to the mainframe at a single gateway. IBM tried for many years to convince corporations that its Token Ring cabling scheme was superior, but eventually this too went the way of the Dodo and now you would be hard pressed to find any Token Ring anywhere in use. One reason was these huge monster connectors:

But mainframe terminals weren’t the only kinds of terminals. There was an entire second collection of terminals that were used to talk to Digital Equipment Corp. VAX computers that used the VT-100 protocols. These just used an RS-232 serial port that was found on the back of most PCs up until the mid 2000′s or so. (RS means Recommended Standard.) The “s” in USB is the modern serial port equivalent.

There are still situations where many industrial, scientific and commercial embedded systems still use RS-232 connectors. I still have an USB-to-serial cable kicking around my supply closet for just those circumstances (not that I can recall having used it in the last several years, but hey, you never know).

Once Ethernet and the Internet became established, this whole terminal market was transformed. As broadband become more prevalent, modems went away and we just used terminal emulation software to connect to a computer across the Internet using TCP/IP. And as VAX and 3270 machines yielded to Unix and Linux, we didn’t need all these specialized tools and emulators.

Over the years emulator companies such as Digital Communications Associates, KEA Systems, Wollongong Group and Walker Richer and Quinn (WRQ) have come and mostly gone, interestingly all bought up by Attachmate. The company still sells more than a dozen different versions of Reflection, which was originally the name used for a brand of emulators to HP minicomputers by WRQ.

Certainly, the terminal emulator has come a long way since those early days. Food for thought the next time you open up a command session on your PC.

Science Fair Entry Shuts Down Airport Terminal

August 8th, 2011 08:47 admin View Comments


OverTheGeicoE writes “A graduate student was returning home from a science fair in Omaha with his handmade entry in his carry-on luggage. When the TSA discovered it, they shut down the airport terminal for several hours, until they could determine it was harmless. All of this has happened before, and all of this will happen again, so before you fly with your homemade Minty MP3 player, make sure you take a look at TSA Blogger Bob’s warning or it could wind up looking like this.”

Evil Al writes “From the ubiquitous Verifone card card terminals to the fancy Apple Store terminals, point-of-sale devices are everywhere. But does anyone know of an open terminal (with printer + Wi-Fi), preferably running Linux, that we can use to run a custom application for retail, made by a reputable manufacturer?”
