8:00 – 4:30 VISIBILITY

• Spent some more time looking at firefox plugin development.After a long talk with Mike, tentatively decided that it was better to go with the DJ Project approach and build a Java wrapper. Spent the rest of the day finding the CVS repo, reading documentation and pondering.

• Tentatively scheduled my Spider training for Jan 5 at 11:30
• Looks like you use the NET command to add users, etc using the command line. There are lots of options:
  • USER – see http://www.windows-commandline.com/2009/05/add-user-from-command-line.html, http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/net_use.mspx?mfr=true
    • net user myUserLogin myUserPassword /add
  • LOCALGROUP – adds, displays, or modifies global groups on servers. Used
    without parameters, it displays the groupnames on the server. see http://www.windows-commandline.com/2009/05/add-user-to-group-from-command-line.html
    • net localgroup myLocalGroup myUserLogin /add – add the user ‘myUserLogin’ to the group ‘myLocalGroup’
    • net localgroup Users myUserLogin /delete
• Once the user is created, then mkGroup -l > /etc/group and mkPasswd -l > /etc/passwd have to be run to make cygwin aware of the new users. Also, new home directories need to be made. Then the new user can telnet in and everything works fine.
• Spent a good deal of time looking at making sure that whatever framework we used could support debugging client code. I think the the choice is reall between two options. Either the debugger (and some/all of the dev environment) browser, or the browser runs in the dev environement
  • Running inside the browser means something like Firebug. They have the flashbug plugin, and my guess is that it wouldn’t be too hard to put in additional pieces if we needed too.
  • The other option is to run the browser in the IDE. The DJ Project seems to ba a framework that would support this

• Now that the basics of the process-based interaction work, I’m going to make it a useful member of the program family instead of the unstable CPU hog it currently is.
  • Added sleep(10) to the processing loops and made everything work with buffered inputs and outputs. CPU usage is unnoticeable, and responsiveness feels the same.
  • Added watchers for the three threads so they all shut down when the user types “exit”
  • Can navigate around through the OS, run maven and other cool things 🙂
  • Cleaned up the user input so that it is split from the thread that watches the keyboard and the method that sends the command to the process.

On a side note, went out for a lunchtime ride and averaged 18.2, including the parking lot. A nice, summery pace on a day with a 37 degree high.

8:00 – 5:30 VISIBILITY

• Ingested some new customer data that has trending! Now I can demonstrate that feature 🙂
• Working on the ExecShell class. It looks like I should be using ProcessBuilder instead. It was introduced in Jva5 and is a bit more sophisticated. Ideally, I need to be able to use the spawned process (shell?) to run multiple commands, while keeping track of the current directory. Going to try to run the “cmd /k” option, then interact through the processes input, output and error streams.
• Moderate flailing on the above. Made some progress. Found the following to try tomorrow:

  • Got it. I was using (char)13 and I should have been using “n” (CR+LF). Whee!

• Meeting with the new TD of S2F, who’s name I can’t recall. It went well. He want’s a diagram of the tables in PPM to figure out what he can do with them. He also liked the idea of being able to use the scripting engine to read and write RESTfully to a Sharepoint DB. Something that he’d like developed is PKI-enabled opening of a dashboard or slide show in VISIBILITY. More as this progresses.
• Spent the morning getting a printout of the structure of PPM.
• More work on the Telnet client/OS interface framework

7:30 – 9:30VISIBILITY

• Meeting with S33P folks Thursday the 23rd at 11:00
• Brought in my other old windows box to Linuxify

9:30 – 12:30 FP

• Finishing paper
• Ordered an audio oscillator and small amplifier kit. I had the thought last night that sound plus vibration could either augment the kinetic interaction, or possibly replace it. If that’s true, then it’s possible that we might be able to get by with simple force sensitive resistors, which would be pretty cool…

12:30 – 5:30 VISIBILITY

• Working on commons-net telnet sandbox application
• Hmmm. MavenAssist isn’t creating eclipse-compatible jars. Looking into that.
• Success!!!  To get the listing below, the program started telnet, logged in to 127.0.0.1, and sent the command ‘ls -la’ to the Cygwin intetd:

• drwxr-xr-x+ 1 phil.feldman ????????       4096 2010-12-15 13:52 .
  drwxrwxrwt+ 1 phil.feldman Administrators    0 2010-12-15 13:26 ..
  -rw-------  1 phil.feldman Administrators  328 2010-12-16 17:02 .bash_history

• Looks like the PPM new features meeting will be here Tuesday or Wednesday of next week at 11:00
• PPM DB still growing and being used. After importing the data for Masha, no activity. Hmmm.
• Let’s see if I can get the Cygwin telnet functioning…
  • Yes, after flailing until 2:00. In the end, I deleted the current install and pulled the version from the gatech ftp mirror. I think that the version at vatech may be corrupted.
• Starting with the java user/telnet manager. I think it will need to do the following:
  • Create/Delete users. Note that this will have to be OS-specific.  In addition, in the case of cygwin on Windows, the user account will have to be added within cygwin as well by running mkpasswd as admin before the user can be logged in through telnet
  • Open a telnet channel on 127.0.0.1. Commands and responses go through this channel. For example “javac foo.java” is the command and error messages from the compiler are the responses.
  • Copy files from the client to the appropriate directory on the server (and with the correct permissions). This may require a pwd command to be run to determine where the user is. Or we do this all graphically (preferred), and keep track on the client
• Spent some time pondering how apps might deploy using dynamically created virtual servers. Looks surprisingly straightforward?

• For the record, I’d like to state that it is too damn cold.
• Fixed Masha’s data
• Had a conversation with Christine about PPM. It looks like they are going to need a new section to track “real-time” inflows and outflows of cash from projects. Head’s up, Dong! Working on scheduling a meeting to go over things in detail.
• Adding the Cygwin Telnet/Ftp server to my machine. So far, here are the steps (from http://www.wiley.com/legacy/compbooks/nilsson/InetdunderWindows2000.doc):
  1. Run “mkpasswd -l > /etc/passwd” at the Cygwin prompt.  This creates the passwd file which is similar in format and function to the Linux passwd file.  Run mkpasswd with no parameters for a usage summary.  You might need to add a -d parameter to grant domain users access.
  2. Edit /etc/passwd and delete everything but the accounts you want to have access permissions.  (In most cases, you’ll end up with only two lines in this file — your account and Administrator.)
  3. Make sure that your home directory (ie, c:cygwinhomephil.feldman) exists.
  4. Right-click “My Computer” and select Properties.  Click the “Environment Variables” button on the “Advanced” tab.  Add a new system variable…the name is CYGWIN and the value is “ntsec” (no quotes).  This tells Cygwin to use your Windows 2000 security.
  5. Add C:CygwinBin to the PATH system variable.  (Stick it at the end, separated from everything else with a semicolon (“;”)).
  6. Run “/usr/sbin/xinetd.exe –install-as-service”.
  7. Reboot!
  8. Well, that didn’t work. Started up the Windows Telnet server for now.  That’s just a matter of turning on the service.
• Looking at the apache.commons-net package as my telnet interface
  • The main project page: http://commons.apache.org/net/
  • An article about commons-net with an example of how to create and use a TelnetClient: http://www.informit.com/guides/content.aspx?g=java&seqNum=40
  • JTelnet is old and probably not supported, but might be useful for reference: http://sourceforge.net/projects/jtelnet/
  • JavaSSH is less old and has more hits. Could also be useful: http://javassh.org
    • Their javadoc: http://javassh.org/download/source/index.html
  • Tom says that Telnet can be made secure by moving it to another port. Also that the xinetd application from cygwin is supposed to be secure.
