Now with the new configuration on yamacraw, getting X windows displayed on MS Windows XP (or similar) is just a 2 step process.

1. Start SSH client on Windows XP, before connecting to yamacraw, click on "Edit" menu then on "Settings". Under "Profile Settings" is "Connection" group within which click on "Tunneling". Tick mark the box next to "Tunnel X11 Connection". Click on "OK" button. Now you are ready to connect to yamacraw and get all X11 forwarding from yamacraw thru the tunnel and display on XP using X manager by performing the next step. SSH program will prompt you to save the settings. Click on "Yes".

2. Start X Manager on your Windows XP. Do not connect to yamacraw thru X Manager. Go back to SSH window and type any x commands such as xclock you should see a Xwindow with a clock in it displayed by XManager. Although, XManager is not used to connect to yamacraw but all the X11 forwardings from the tunnel thru SSH will be rendered by XManager. You can simply type magic at the command line and you should see the CAD editor displayed. I have successfully tested all of the above including magic just few minutes ago. Also, you can run matlab from the command line and get the XWindows GUI displayed on your PC.

I am using DSL connection without any real IP address assigned to my home network.

[From R. Timothy Edwards:]
"The "flock_list" directory is a result of selecting the "file locking" option when doing the "make config" stage at the beginning of the compile and install process. If it's producing an error, it's because that particular version of the file locking is broken, although the only effect you should notice is the error message." [See the above mentioned webpage for this quote.]

We have installed Magic on all the Redhat Workstations except cs400dell104, 105, 107, 125 (the older black dell machines at the wall next to the white board) in CS400.

When you login to the workstation DO NOT SSH to yamacraw. Rather at the command prompt of the local workstation do the following:

bash-2.05b$ export CAD_HOME=/opt/cad/magic-7.1
bash-2.05b$ export PATH=$PATH:/opt/cad/magic-7.1/bin
bash-2.05b$ magic

Eventually you will not need to set the above environments, we are trying to have the same environment settings on the workstations as well as on yamacraw. In couple of days, we will be able to synchronize the settings then all that the students need to do is login to the workstation as usual and open a shell window (right click on desktop and select "New Terminal") at the command prompt type magic that's all.

bash-2.05b$ magic

I have tested it myself. Magic works fine on the Redhat workstations (on the all 6 rows, not those near the wall).

Since students will be running Magic locally on the workstation without logging in to yamacraw server, we hope that all the students should be able to work on individual workstations and the server will not be burdened with the several processes of Magic.

We plan to install Matlab also on the workstations in next few weeks. I had one of your students asking for skiff(cross compiler) that is available on the 4 older black dell machines next to the white board, next to the wall. Skiff is installed in the /skiff directory at the root on those 4 Redhat machines.

Once we have the machines labeled with host names it will be easier to refer to them by names.

PS: Please ask students NOT to run Magic from yamacraw while they are in the CS400 Lab instead they should use the local installation of magic on the workstations.

All student account passwords on yamacraw.cs.gsu.edu have been reset to the last 4 digits of their student ID. The usernames remain the same. Student directories are untouched. Only the passwords have been changed.

We have migrated to a different LDAP server on yamacraw, we hope it to resolve the problems that we had with the previous LDAP server.

Anytime we reboot yamacraw server or the network cable was unplugged from the the Redhat workstations then the workstations will loose the student directories mounts. Rebooting the workstation will automatically mount the home directories on the workstations. You can let the students know about properly rebooting the workstation in case home directory was not mounted after login to the workstations.

Please inform them in the class. I will also send them emails. I will have to migrate the faculty acounts as well which I am planning to do by tomorrow. Nisar Hundewale

I have just installed spice3 on yamacraw at /opt/sfw/spice3f5 students will need to include these lines in their .bash_profile

export SPICE_LIB_DIR=/opt/sfw/spice3f5/lib
export PATH=$PATH:/opt/sfw/spice3f5/bin

all the spice binaries are in the above directory. there is an example directory within the installation dir that contains some .cir files.

We will install spice on workstations as well. until then stdents need to ssh to yamacraw after they login to workstations in cs400 lab and run any of the binaries of spice.

Once we install spice on the workstations then they will run the local copy of spice therefore they should not SSH to yamacraw to run spice.

[There is a problem with submitting homework 4.] Go ahead and e-mail your homework files to the TA (Sharareh Babvey). Instead of creating a log file, you can print out a copy of the email.
