February 04, 2009 -- Self Account Creation is no longer available

Citing a recently discovered security vulnerability, ITS has turned off all access to the Self Account Creatio n system.

This is the system most students use to create accounts on ECES and is one way of changing your ECES passwords .

All indications are that the deactivation of SAC is permanent.

Look for new account creation procedures here:

Create an Account

And new password change procedures here:

Changing your password on ECES

Welcome back for Spring 2009!

Just a few notices:

Power Saving

We have setup many of the lab computers to go to Standby mode after 45 minutes of inactivity.

To wake a computer in Standby mode, simply press a button on the keyboard.

If that fails, you can press the power button on the computer to wake it up.

If that fails, it is probably not in Standby. Try turning it on and/or plugging it in -- not in that order.

Broken Equipment

Please report all broken equipment.

Please DO NOT attempt to fix broken equipment yourself.

Please DO NOT trade the broken equipment at your lab bench for working equipment at some other lab bench.

Report broken equipment to:

  1. ecehelp@colorado.edu

  2. Wayne Gardner

  3. Matt Lessem

  4. Anyone hanging out in ECEE 1B10A (behind E-Stores)

Thanks.

Have a good semester.

Welcome back for Fall 2008!

The biggest news is that we have completely replaced the troubled storage system on ECES.

We believe this system was the cause of all of our stability issues in the Sprin g 2008 semester. We're hopeful that those problems are solved.

We will also be getting new printers in ECEE 2B39, the Embedded Labs, and ECEE 2 B37, the Logic Lab. These should be here the first week of classes.

01/30/2008
The scheduled power outage announced below did not happen.

We are waiting to here when it will happen.

ECES TO BE UPGRADED 02/01 - 02/02

ECES and all labs will be down for a scheduled upgrade from 9pm Friday, 02/01 until 5pm Saturday, 02/02.

01/13/2008
Happy New Year and Welcome Back for Spring 2008!

We have some exciting (good) things coming up for ECES and the ECE Labs in the first month of the new semester.

IMPORTANT NOTICE:

You may not know this, but the Engineering Center has been running out of electricity. You can see how that would be a bad thing for our department in particular.

Fortunately, the good folks in the Dean's office, CU Facilities, and a lot of hardworking contractors have been working to bring us more of those electrons we all enjoy.

Unfortunately, this means that most of the Engineering Center will be without power at unpredictable intervals on SATURDAY, JANUARY 19.

To protect our sensitive computer equipment from damage due to power loss/fluctuation, all of the Electrical and Computer Engineering servers will be SHUTDOWN from Friday evening until early Sunday morning.

Additionally, all of the computers in the ECE Undergraduate Labs and SRC will be turned off on Friday night.

This means FROM FRIDAY, 01/18, in the PM to SUNDAY, 01/20, in the AM:

NEW COMPUTERS:

If a fresh supply of electrons isn't enough to get you excited about the semester, how about fresh new computers.

We recently purchased two new Dell servers and a new Janus raid system to upgrade eces.

This new system should improve performance and file access times in all of the ECE Undergraduate labs as well as provide increased stability -- including a fancy new failover system that will minimize any downtime due to hardware failure.

The new eces isn't quite ready to take over, but we're expecting to make the switch early in the semester.

We're also expecting to see new computers for the SRC sometime in the Spring.

11/29/2007
IMPORTANT: If you use eces as your CU mailhome (most of you do not), then you need to pay attention to this:

Eces has been listed on CU's spam blocklist on and off for the last few days.

This DOES NOT AFFECT INCOMING EMAIL.

This only affects your ability to use eces.colorado.edu for outgoing e-mail.

There is very little information as to why, and it is possible that there is nothing I could have done to prevent this.

I will be reconfiguring eces to only accept authenticated connections, this might help clear it from the blacklist eventually.

Meanwhile, and in general, I welcome those of you using eces.colorado.edu as your outgoing smtp server to simply switch to smtp.colorado.edu. The proper settings are: authentication, TLS, port 25. Use your IDENTIKEY to authenticate.

ECES had a difficult Fall Break.

Two things were scheduled to happen to Eces over the Fall Break.

First, the ECE server room was scheduled to be rewired by the ITS wiring contractors. This is part of a campus-wide initiative to replace older cat-3 cabling with shiny new cat-5e cable. It is generally a good thing.

Second, Eces was scheduled to be down on Tuesday, 11/20, for scheduled disk maintenance. This maintenance would address the recent problems we've been having with the quota system on Eces.

Unfortunately, the rewire work caused a significant disruption to the normal cooling and airflow in the ECE server room and this resulted in a hardware failure on Eces.

This hardware failure was resolved at approximately 10am on Wednesday, 11/21.

At this point, I was able to begin the scheduled disk maintenance. This lasted until approximately 8pm on Wednesday, 11/21.

On Friday, 11/23, I was notified that Eces was not correctly routing traffic from the ECE Undergraduate Labs. This problem was quickly corrected.

08/21/2007

New for the Fall 2007 semester:

We've been busy!

Many of our labs have relocated:

ECEN3100 aka Logic Lab --> Now in ECEE 2B39.
ECEN4613 aka Embedded Design Lab --> Now in ECEE 2B37.
ECEN4623/33 aka Embedded Real Time & Hybrid Lab --> Now in ECEE 2B37.
ECEN4610 aka Capstone Lab --> Now in ECEE 1B24 and 1B32.
ECE Cad aka ECE Linux Lab --> Now in ECEE 283.

There is now a printer located in 2B39.
To use it, just do Start:Run \\blacksun\logic-printer.

We have also given up a portion of the Circuits Lab to the Aerospace Department.
The Circuits Lab is now ONLY accessible through ECEE 281 (not ECEE 275).

ECEE 287, formerly the CAD Lab, will be used as recitation space for Circuits Lab classes.

Also...

There is a new, easy to use, menuing system on eces.colorado.edu

If you SSH to eces.colorado.edu, you will be presented with a menu that will allow you to easily change your passwords and perform some other basic tasks.

If you want/need to access a Unix commandline interface, you can SSH to eces-shell.colorado.edu.

You can still access your eces/METAVERSE files by connecting to eces.colorado.edu with SCP.

04/11/2007

New for the Spring semester:

There are new computers and monitors in the Components and Logic Labs.

We've been having some issues with PLUS setting passwords correctly.

If you try to create an account with PLUS or set your password with PLUS, and it does not work, please try again. This time, use a password that contains only capital letters, lowercase letters, and numbers.

Thank you.

01/16/2005

E-mail problems:

Due to some misconfigurations on Saturday, e-mail address resolution was not wor king correctly. This has now been repaired.

01/15/2005

Maintenance on Saturday, January 15 took longer than expected, and ECES was down from aproximately 9:15am until aproximately 1pm.

Unfortunately, we were unable to correct all of the problems encountered on Satu rday, and ECES will once again go down for maintenance from 12pm to 4pm on Monda y, January 17.

We regret the inconvenience, but these short down times early in the semester sh ould prevent problems in later, more critical periods.

08/23/2004

Roaming Profiles Changed/Reset
You can find the text of the e-mail you should have received concerning this here:

Roaming Profile Changes -- The E-Mail

07/12/2004

New Certificates
ECES has new ssl certificates for secure web browsing and for secure IMAP and POP e-mail access. As before, these are self-signed certificates. They are not meant to "authenticate" that you are talking to eces, just to encrypt that communication.

12/23/2003

Upgraded SpamAssassin to v.2.61, SquirrelMail SA config to 2.3.2
New SpamAssassin should help with spam filtering. The SquirrelMail plug-in for SA config was also upgraded. Unfortunately, system-wide Bayesian filtering is still not going, but we are working on it.

PGP/GPG SquirrelMail plug-in installed
On an unrelated note, we installed the PGP/GPG SquirrelMail plug-in. You'll need to figure out PGP/GPG keys for yourself, but the encoder/decoder is there.

12/07/2003

Non-ECE Major Accounts Expire 12am 01/01/2004
ECES Users whose accounts are set to expire 01/01/2004 have received an e-mail from ecehelp. You have until 12/19/2003 to purchase a copy of your data on CD for $5. After 01/01/2004 a CD of your data will cost $10. CDs can be purchased in ECEE 1B10A.

Of course, the easiest thing is for you to simply copy your data off of ECES by 01/01/2004

11/06/2003

New ECES Policies Concerning Use and Processing
Everyone needs to go read two new sections on the ECES Policies web page: "Use and Purpose of ECES" and "Processing and User Binary Policies for ECES".

10/20/2003

New Printer in Circuits Lab
Last week, we installed a new Dell M5200N Printer in the ECE Circuits Lab. The M5200N is faster and more efficient than the old HP 8150, but it currently does not support double-sided printing.
You can print to the M5200N without reinstalling the \\blacksun\circuits printer, but to gain the full functionality and correct printer options, we suggest removing and re-adding the printer. This will update the drivers in your roaming profile to better match the new printer.

10/07/2003

Quota increase on ECES
Based on the number of users and the available disk space on eces.colorado.edu, we were able to increase students' disk space quota to 665600K or 650MB: roughly the capacity of one CD-R. Before taking advantage of your newly available storage space, please review the Data Storage Policies on the ECES Policies page.

09/25/2003

Reminder to get data from eceuglab-pdc
This is just a a reminder that the old ECE Lab server, eceuglab-pdc, will be brought down on 11/01/2003. To get your old data to your new eces account, follow the directions here:
ECEUGLAB-PDC Data Transfer

09/05/2003

Password Problems
A few users have had problems logging in to the labs despite being able to connect to the server with ssh. We believe this is due to a problem which existed when their accounts were created and which has since been fixed. If you expereince this problem, you can try resetting your password with PLUS or you can e-mail ecehelp@colorado.edu or come by ECEE 1B10 to have your password reset by us.

August 22, 2009

Welcome back for Fall 2009!

Temporary Printing Solution

Due to a software issue on our primary print server, we have setup a temporary print server: eces-print

To ease this transition, we have setup a script which should automatically add all available printers to your Windows Roaming Profile.

However, a number of things may go wrong while this script is running.

If you find you do not have the printer you want, follow these directions:

Printing in the ECE Computer Labs

Please be patient with our temporary solution. We hope to have a permanent solution up ASAP.

New Account Creation and Password Reset Procedures

We have a new site for Self Account Creation and Password Changes on ECES.

To create your account and/or reset your password on ECES, you can visit:

sac.colorado.edu

An identikey and identikey password is required.

As always, if that doesn't work for you, e-mail ecehelp@colorado.edu.

ECES "Z" Drive Available Outside of Labs

You are now able to mount your "Z" drive on ECES -- your home directory -- from outside of the ECEE Undergrad Labs.

If you are on-campus, you can simply choose "Map Network Drive" from a Windows machine or "Connect to Server" on a Mac.

From off-campus, you can use the CU VPN to gain similar access.

See below for details:

ECES SMB Connect

Just a few notices:

New Logic, DSP, Communications, Embedded Hybrid Systems Lab

ECEE 1B79 has been remodeled to host 12 workstations which will be used for Logic Lab, the DSP Lab, the Communications Lab, and the Embedded Hybrid Systems Lab.

Please respect the lab schedule which will be posted on the lab door.

New Workstations in Circuits and Embedded Systems Design/Real Time Labs

HP Z400 intel i7-based workstations have been installed in the Circuits Lab in ECEE 281 and in the Embedded Systems Design/Real-time lab in ECEE 2B39.
