June 5th: partial EDU site downtime for PDU/power upgrades
Tuesday, June 1, 2021, 2:31PM; posted by jdbarnes.

There will be some power upgrades at the USC CoLo site which houses the EDU nodes on Saturday, June 5, 2021, 12:30pm – 3:00pm. Nodes should return to function after the work is completed, however, if there is a specific node or set of nodes in your experiment that are giving you trouble, please create a trouble ticket for Deter ops to take a look at the nodes giving you trouble.


Swap in problems [RESOLVED]
Thursday, May 27, 2021, 1:50PM; posted by jelena.

[UPDATE - We resolved the issues.] We are experiencing some swap in problems. Our team is looking into this and will update this news item when issues are resolved.


Downtime extension
Monday, May 17, 2021, 3:35PM; posted by jelena.

As you know, downtime was scheduled for Tuesday, May 11, 2021 to Monday, May 17, 2021 to install new nodes and switches and new backend software in Deterlab.

During the past week, the following was completed:

  • All cabling and power systems were removed and sufficient space was cleared to add new nodes as well as core infrastructure  
  • By Thursday, May 13th, all switches have been replaced and cabling has been modernized. The core infrastructure was powered up, the team began to re-initialize Deterlab.  
  • By Friday, May 14th, Deterlab had been fully rewired and services were coming up.
We’re close but Deterlab is not fully up yet. A few main switches have connectivity and VLAN issues that we are actively investigating. All our engineers are on this task. We estimate that it may take us a few more days to fully recover the testbed. We will notify you promptly when we’re back! Thank you for your patience and understanding.


Major Downtime May 11-17
Monday, April 26, 2021, 6:08PM; posted by jdbarnes.

Please see the news item about "Downtime in February", This downtime has been moved to May 11 - May 17 Please expect up to 6 days of downtime. Please plan accordingly. We will attempt to minimize the downtime for Deter while doing the hardware work. We will post another news item as the date approaches.


Planned Infrastructure Power Testing (2021, June 4th)
Monday, March 22, 2021, 1:17PM; posted by jdbarnes.

There will be a planned power outage of all infrastructure power lines from 7PM to 12AM PDT on June 4th 2021. Please be sure to leave room in your schedule for a potential gap in service, if the power testing lasts longer than the UPS (battery) for DeterLab infrastructure.

Python/pip local mirror
Monday, February 1, 2021, 3:00PM; posted by jdbarnes.

There has been a sustained high volume overuse of pypi web search interface, which has resulted in pypi turning off search for python packages.

Due to this, and to some requests for an available internal mirror for python packages, there is now a static mirror of most python packages at "https://fbsd-build.isi.deterlab.net/pypi/web/simple".

To use this internal mirror, the pip installation stream looks like "pip install -i https://fbsd-build.isi.deterlab.net/pypi/web/simple [package_name]".

We will attempt to get a searchable index running soon.


Downtime in February [Mid May - COVID delay]
Thursday, December 24, 2020, 4:40PM; posted by jelena.

Happy holidays! We know this year has been challenging for everyone and we hope your access to Deterlab has helped you in your distance learning and teaching. We are looking forward to serving you further in 2021!

We have some exciting news to share with you! Through a new award from NSF we will be modernizing Deterlab. The current network switches will be updated, and the older PC nodes will be replaced with high-density nodes, which will allow for faster computing speeds. In addition, we will be migrating the original Deterlab management software based on Emulab, to the modular and modern Merge software. Already running several other testbeds, Merge was developed by a team of DeterLab research software engineers in 2017 and aimed to optimize testbed environments through features like multi-device support and the ability to have a clear separation between the experimenter space and the testbed resource space.

This modernization effort will allow researchers to perform experimentation at a greater scale and complexity, and will also make it easier to use for novice researchers.

Maintaining operations and support for our user community is extremely important to us. We are developing plans for a staged transition and will be reaching out to some of you to serve as early adopters on the modernized system.

In the immediate future there will be some visible changes and down time. Specifically:

  1. clusters of nodes (e.g., all Microclouds) will be unavailable for a few days between February 1 to February 14. the entire testbed will be unavailable for up to 2 days, most likely February 3-4. We will announce the exact dates when we set them.
  2. from February 1 to June 1 we will support both the old and the new version of Deterlab, but nodes will slowly be drained from the old version to rejoin the new. This means users will slowly need to transition to the new version of our testbed, which deploys a new set of user interfaces and experiment definitions. We will transition users in phases and will ask for volunteers for each phase. We will provide migration mechanisms for all your data to be either moved to the new testbed or saved to your machine.
  3. educational users will retain access to old testbed for foreseable future, i.e., they do not have to transition to the new version.

Please monitor the Message of the Day. You can also find this information at our News page. Please feel free to reach to deter-ops@isi.deterlab.net with any questions about this transition.


Ubuntu1804-STD end-node traffic shaping
Thursday, November 5, 2020, 11:02AM; posted by jdbarnes.

The end-node traffic shaping feature has been debugged and enabled for the supported Ubuntu1804-STD image.


Heavy usage considerations
Thursday, November 5, 2020, 9:38AM; posted by jdbarnes.

Please try to limit your use of the users.deterlab.net host's bandwidth as it is a shared resource.

If you write files in your experiment, please write them to local disk, then move to users (that is, your home or project directory) once your experiment is completed. Your home directory is NFS mounted in all experimental nodes, so writing files there during an experiment will utilize bandwidth.

If you need to do large (30+ nodes) multi-threaded orchestration, please consider using an existing node within your experiment for this, or allocating an additional node for control of your experiment.


Network infrastructure issue (leaf3)
Tuesday, September 22, 2020, 10:25AM; posted by jdbarnes.

UPDATE2: sm49-64 do not have experimental networks until the switch hardware is replaced. The rest of the testbed is unaffected by this issue.

UPDATE: There is a temporary fix in place that should allow most experimenters to swap-in until the switch hardware issue has been resolved. The exception will be [sm] type nodes, which are served by the malfunctioning switch.

A switch that serves the experiment networks has experienced a failure and is being investigated. Please stand by while we troubleshoot and repair the issue.

System Release Announcement: Containers v1.1
Monday, June 20, 2016, 1:45PM; posted by alba.

All components in the DETERLab Containers System have been upgraded as of June 15, 2016. The host OS for all containers is now Ubuntu 14.04. The QEMU-KVM package was upgraded to 2.51-1 and all OpenVZ components were upgraded to the latest versions.

Virtual Distributed Ethernet (VDE) was dropped as the QEMU-KVM network implementation and replaced with a Linux bridge/tap mechanism. This gives an order of magnitude speed increase for QEMU-KVM networking from roughly 450 MBs to 4.5 GBs.

The Berkeley end of the intercampus tunnel was upgraded to 10 gig on Saturday

The ISI router and endpoint will similarly need to be upgraded before full use of it can be made.

Please expect additional downtimes where experiments will be frozen in place, but we hope with only limited disconnection time.


Expected Downtime August 17
Thursday, August 13, 2015, 9:38AM; posted by jross.

On Monday, August 17th, we are expecting a power interruption while a faulty UPS is replaced. This power interruption will bring down boss, users, and nearly all of the new dl380g3 nodes.

Please plan your experimentation accordingly!

We experienced a complete power loss at ISI and have disabled swapping until we have everything back up and running correctly.


swapping re-enabled
Saturday, March 14, 2015, 12:01AM; posted by jross.

An unanticipated dependency on a switch which we removed cost us some troubleshooting time, but the testbed is now back and ready for your experiments!


Control Net Interruption
Friday, March 13, 2015, 9:46AM; posted by jross.

Some control net traffic had a legacy routing through a switch which we have removed. We are working to re-route this traffic. In the meantime testbed functionality is impaired. We recommend waiting until we have posted that this is resolved before attempting to swap or modify any experiments.


Downtime Alert! DETER buildout begins March 13
Friday, March 6, 2015, 2:15PM; posted by jross.

Starting on the morning of March 13th, we will be upgrading the DETER testbed with new nodes and switches. Importantly, the pc3000 and pc3060 nodes are being replaced with more modern hardware. The pc3000 and pc3060 nodes will be shut down, so any experiments using them will need to be swapped out before the upgrade begins. Testbed capacity will be heavily impacted by this for the week which we are expecting this buildout to take, so please plan accordingly.


Testbed Crashed -> UPS failed 3/3/15 10:30 PST (3/4 6:30 UTC)
Wednesday, March 4, 2015, 1:08AM; posted by sklower.

All the servers went off the air earlier tonight due to the failure of a UPS.

The power has been bypassed to unfiltered; this could mean another sudden crash of the testbed; we hope not. Many of the machines came back up on their own so rather than take them back down again, we completed the restart.

If you can delay your work for a couple of days, ti might be prudent to do so


Problems swapping in
Tuesday, March 3, 2015, 1:39PM; posted by jelena.

We are currently experiencing some problems swapping in experiments and are working to resolve them.

The cause has not yet been determined, although it seems to come and go and the testbed is currently functioning.

I'm using the standard scheduled downtime today to freshen up the ports on boss and users. Swaps should be enabled by 7PM Pacific.


node_list moved to node_summary, node_list restored and make consistent
Friday, October 11, 2013, 5:50PM; posted by faber.

The node_list command now queries the XMLRPC interface as it used to do. Users who have been using script_wrapper.py node_list to access this function should use /usr/testbed/bin/node_list instead.

The node_list -c flag that outputs containerized node names has been modified in two ways. First, names are produced without the DNS qualifiers as node names provided by other options of this commmand are. A node in a VM container named a will be reported as a not a.exp.proj as earlier versions of this feature did.

The node_list -c flag now reports embedded_pnode containers as well (physical machines). If no containers VMs are present in an experiment, node_list -c and node_list -v produce identical output.

The node_list command is now available as node_summary. It is otherwise unchanged.


Containers now report hostname in same format as physical nodes
Friday, October 11, 2013, 11:25AM; posted by faber.

Users of containers should be aware that both openvz and qemu containers now report hostname as a fully-qualified domain name (FQDN) just as physical hosts do.

A container named a in the tcl file will now report its name as a.exp.proj.isi.deterlab.net rather than a.

This should simplify moving from physical nodes to container VMs.


Kali 1 Replaces Backtrack 5R3
Monday, August 12, 2013, 12:03PM; posted by bks.

This year Offensive Security named their penetration testing release "Kali" instead of "Backtrack." DETER now supports Kali 1 instead of last year's Backtrack 5R3.


Changes to DETER instructional policies and proceedures, 2013
Friday, July 12, 2013, 2:47PM; posted by sklower.

1.) We will no longer generate passwords in advance for new accounts; when students are assigned to the class they will get an email with the URL for "forgot your password", prepopulated with their class ID, as part of the welcoming letter.

2.) On the day that the end-of class is reached, all accounts will be locked - encrypted password set to '*', ssh keys and ssl certs deleted, web_frozen asserted; and email will be sent to the instructor appraising them of the action.

3.) 4 weeks after the class end date, all accounts will be *wiped* (files removed, email aliases removed, new ssl certs, generated).

2 weeks after the class end date, we will send email to the instructor reminding them of the imminent wipeage. If the instructor wishes to delay this, they can update the end-of-class date.

4.) We will formalize the notion of incompletes; a student account which is marked as being granted an incomplete will not be wiped.

If the incomplete is granted before the end of class, the account will not be locked.

If the incomplete is granted after the class ends but before it is is wiped, the account will be unlocked, but the student will need to set the password again in the manner they did at the beginning of the semester.

5.) Class limits will be strictly enforced for normal students; there will be an entry in the group_polices table setting the limit for nodes to be 0 whenever the instructor has not input a schedule entry.

Instructors must set an end date at the same time or before they enter class limits; nodes may not be reserved past the end date.

Instructors, TA's, and students making up incompletes will be exempt from the schedule limit, and nodes which they have in use will not be counted against a class limit.

The exemption for incompletes MUST NOT BE USED for anything else - if a professor is teaching a grad class and has students who want to parlay a final project into a conference paper, the instructor MUST apply for a separate research project!

6.) Instructors will be unable to assign students to classes until a future end date is set.

We believe the only active class currently using DETER is the ComSecHu project - all others have been assigned a presumptive end date of July 16th, so class accounts will locked on that day, and wiped 4 weeks later.


Regenerating testbed-specific keys this Wednesday Evening
Saturday, January 19, 2013, 5:59PM; posted by sklower.

Clarification:The account was not compromised at DETER itself. This change was based on our experience with an intrusion outside of DETER where the collection of ssh private keys was part of the attackers toolkit.

Due to a compromised account, we believe that it is prudent to configure ssh in such a way that when one logs into users or boss from the outside the sshd will consult an authorized_keys file which is not exported to experimental nodes and would not contain public keys generated on your behalf by the testbed.

A file users:/etc/ssh/external_keys//authorized_keys writeable by you will be created, although you should let the system manage it for you.

In order to log into experimental nodes, and from one testbed node to another, locally generated ssh public and private keys will be where they used to be.

Any public keys that you have previously uploaded via the web interface into the testbed should continue to work, and both places should be automatically maintained on your behalf.

We were, of course unable to run the utility to make the transition during the UN-scheduled downtime on saturday morning, and will do instead on wednesday.

All experimental switches at ISI are now connected to a single HP 5412 switch using a pair of 10Gbe interfaces for each of the 6 experimental 5412 switches. This is a major upgrade over our previous experimental topology at ISI which was only partially 10Gbe. Also, the last Nortel switch which was serving the pc3000 machines has been replaced with a pair of HP 5412 switches. The ISI side of the switch upgrade is now complete.


Experimental Switch for the pc3000 machines to be replaced Friday Afternoon
Wednesday, January 11, 2012, 11:06PM; posted by jhickey.

As the final part of the ISI switch upgrade, I will be replacing the Nortel stack that currently supports the experimental interfaces of the pc3000 machines. Additionally, I will be switching our network topology to a star topology with 20 Gbit interconnects. Experimental swap-ins will be limited during this time and experiments that incorporate multiple node types at ISI (this switch currently acts as the head switch at ISI) will have their connectivity disrupted. I should begin work on this around 3 PM Pacific time. Swapping out such large switch stacks takes a fair bit of time. I expect the testbed to be back on the air by 12 AM Friday night.

DETER announces the deployment of the new delay nodes, based on the Click modular router. Beside supporting functions provided by old delay nodes, they facilitate specifying sophisticated loss models that allow burst losses. Moreover, they emulate variable and static delays. Variation in delay is described by Normal, Poisson or Exponential distribution. We encourage users to use them. All you have to do is to replace “make-lan” or “duplex-link” by “make-deter-lan”.

Introducing ThirdEye is a semantic analysis framework
Tuesday, June 21, 2011, 2:22AM; posted by jhickey.

We have a new analysis tool for researchers to use with DETERlab experiments: ThirdEye. ThirdEye is a semantic analysis framework to identify interesting relationships in network and cybersecurity experiment data. If you want to explore what is going on in your experiment, or automatically ensure every experiment trial is valid, you will find ThirdEye useful.

Web Login by email address is no longer supported.
Wednesday, March 23, 2011, 6:01PM; posted by jhickey.

DETER no longer supports using your email address instead of your DETER username when logging into the web interface. Allowing the use of email addresses instead of usernames for the web interfaces appears to have caused a fair amount of confusion for new DETER users as to what their username really is. In order to be consistent with the username supplied when logging into testbed nodes and users, we have disabled the ability to use an email address for the web interface.

Taking disk images and snapshots made easier.
Thursday, December 2, 2010, 7:12PM; posted by jhickey.

We have changed the way that disk images and snapshots are created. We now have links in the 'Reserved Nodes' list in Experiment Information to easily allow you to create new disk images and take snapshots.

By specifying the node up front, we are able to inherit all the metadata from the image that is currently running on the node. This means that end users will no longer need to select partitions or which nodes an image supports. We hope this will eliminate confusion about which nodes an image supports and what partitions scheme is used.

Please contact us if you run into problems with this updated functionality.

Berkeley bpc2133 nodes once again available

the cooling system in the berkeley black box has been repaired. The failure was due to a mixing valve under servo control; the water supplied by the building is too cold, and so it it is mixed with recirculated water. The valve at this location seems to fail and need to be replaced every 6 - 9 months; we now keep a replacement part *on site*, but we are not a liberty to replace it ourselves; only somebody from the central campus maintenance division is authorized to inspect, and either replace themselves or hire a contractor, and the office responsible is not staffed on weekends. At least this time we did not have to wait an extra 3 days to have a spare valve manufactured and shipped to us, but it is almost certain that this will happen again in another 6 to 9 months.
