| |
| − | | |
| − | ::JHU Facilities is preparing for BGE to test electrical equipment that affects several Homewood buildings. They will be performing this test on Saturday evening, June 26 at 8pm. If you recall, back on May 6, there was a very short power outage that affected our building and others. The testing BGE will be doing is part of their troubleshooting what happened in May.
| |
| − | | |
| − | ::In the case of the upcoming 6/26 testing, there is a potential for another short power outage (1 to 2 minutes) that evening.
| |
| − | | |
| − | ::A short outage of this type will affect our CS servers and IT services in the following way: Although our servers should physically stay running, as they are on battery-backed equipment, because our services require network connections that are controlled by JHU (and not on battery backup), all of our CS IT services will be unavailable during the expected brief outage.
| |
| − | | |
| − | ::Once the power returns, our services should be available again, because the network should be available again.
| |
| − | | |
| − | ::Also, if there is indeed an outage, the CS Grad and Undergrad Lab systems (that currently, you can only access remotely) will power off. However, when power is restored, those lab systems should automatically reboot.
| |
| − | | |
| − | ::Other notes: WiFi and other networking in the building would be unavailable during the outage. Most likely, lights would be unavailable. My group does not maintain J-Card systems, so we do not know how the J-Card readers will perform during a power outage.
| |
| − | | |
| − | ::''For your own equipment, whether it be in your office or the server room, please prepare as for any other planned power outage.''

| |
| − | | |
| − | '''DETAILS:'''
| |
| − | :Our CS Grad/Research Net home directory file server, ''rtfm.cs.jhu.edu'', will be rebooted so that a time-sensitive, required update can be applied. We will apply the required update this coming Tuesday morning, Oct 13, starting at 5am. We expect the reboot and configuration to take no more than an hour if all goes well.
| |
| − | | |
| − | : During the process of applying the update, several of our CS services will be unavailable. A list is below.
| |
| − | | |
| − | : If there are any unexpected complications during the update process that will delay the restoration of services, we will update this CS IT Support Wiki's Notices page.

| − | ====Major Malone Power Outage Planned, Affecting CS IT Service - October 23, 2021====
| |
| − | :'''WHAT:''' There will be '''''no''''' CS IT computing services available during an upcoming major power outage for ALL of Malone Hall.
| |
| − | | |
| − | :'''WHEN:''' Saturday, October 23, 2021, ''all day'', from '''6''am''''' until sometime around '''10''pm'''''.
| |
| − | | |
| − | :'''DESCRIPTION:''' JHU is planning an all-day power outage for Malone Hall. As such, all of our computing services will be unavailable during that time.
| |
| − | | |
| − | :The actual power outage is planned to start at 7am and end at 8pm on Saturday, October 23. However, we need to safely bring down our computer servers and clients earlier than that (before the power goes out.) We plan to bring our systems down around '''6am''' that morning. And although the power should be up around 8pm, we will not have all our systems back up and running until approx. 10pm, so plan on about 2 hours after the power outage is deemed over until our servers and services are available again.
| |
| − | | |
| − | <!--
| |
| − | :<span style="color:#ff0000">Please read all of the notes below regarding Malone Hall Residents, CS Server Room users, and a list of the CS IT services that will be unavailable during the outage. </span>
| |
| − | -->
| |
| − | ::<span style="color:#ff0000">'''NOTES TO MALONE HALL RESIDENTS:'''</span> During the time of the outage, we're assuming most building lights will be out and the J-Card system might be out too. That might make it more difficult to get into the building during the outage. But with the power out, we're not sure how much need there will be for anyone to be in the building during that time anyway. If you have an office refrigerator, expect that to be out too. If you are counting on your UPS (battery-backup) systems to continue powering your office equipment, please realize that this is an expected over-12-hour outage. And keep in mind that your office phones may be inoperable during the outage. So please plan in advance for this outage.
| |
| − | | |
| − | ::<span style="color:#ff0000">'''NOTE TO CS SERVER ROOM (MH G-29) SERVER OWNERS:''' </span> Our server room will be out of power, so our servers will be unavailable. If you host servers in the server room, your servers will be down as well. Plan ahead of time to shut down and to bring back up your servers. Your group is responsible for any systems you choose to shut down before the outage or boot back up after the outage.
| |
| − | | |
| − | ====Tracking Our CS IT Services Status Updates During The Outage====
| |
| − | | |
| − | :Because we will not have power to our servers in Malone Hall, the CS IT Support Wiki, and especially this Notices page ( https://support.cs.jhu.edu/wiki/Notices ) will be unavailable during the outage. Instead, during the outage, we have arranged for status updates to be available at the following website (served at an off-site facility):
| |
| − | | |
| − | ::[https://csstatus.jhu.edu https://csstatus.jhu.edu]
| |
| − | | |
| − | :(Bookmark that link ahead of time, in case you can't access your CS mail during the outage.)
| |
| − | | |
| − | :As soon as we're able to do so after the outage, we'll also make this Notices page available again.
| |
| − | | |
| − | ====CS IT Services ''Un''available During The Power Outage Include...====
| |
| − | | |
| − | * DNS resolution (hostname lookups) for all cs.jhu.edu hostnames will be unavailable. This will affect all websites with cs.jhu.edu domain names, even if the website is hosted by someone other than the CS department.
| |
| | | | |
| − | * CS Mail service, both incoming and outgoing, will be suspended for CS Grad/Research Net users. And some CS email services will not be available for CS Ugrad Net users.
| + | == {{red|CS COMPUTING LAB AVAILABILITY}} == |
| − | ** Incoming mail ''should'' be queued by the sender until our mail service is back up again. Outgoing mail will not be available. | + | <!-- ***** NORMAL POSTING MH 122****** --> |
| − | ** Outgoing CS mail will not be available to Grad Net users, but since CS Ugrads can send through the JHU mail server, CS Ugrads might still be able to send email during the outage (just not from a Malone Hall–based computer.) | |
| − | ** IMAP, POP, and webmail (for both Grad/Research and Ugrad accounts) will be unavailable.
| |
| − | | |
| − | * '''No''' CS webpages will be available. This includes the main CS website. And, as mentioned above... because we will not have power to our servers, the CS IT Support Wiki, and especially its Notices page will be unavailable during the outage. Please refer to https://csstatus.jhu.edu for status updates during the outage.
| |
| − | | |
| − | * Grad/Research Net and Ugrad Net user accounts and home directories will be inaccessible during the power outage. | |
| − | | |
| − | * ssh service to our CS Grad/Research Net & Ugrad Net Linux boxes (masters1 through masters16, ugrad1 through ugrad24, gradx, gradz, ugradx, and ugradz) will be unavailable. | |
| − | | |
| − | * Console (desktop) access at any of our lab Linux client systems will be unavailable. | |

| |
| − | :'''WHEN:''' First identified in CS, last week of January, 2020. '''''UPDATES below the DETAILS section...'''''
| |
| − |
| |
| − | :'''DETAILS:'''
| |
| − |
| |
| − | ::As you know, recently, we upgraded our lab Linux clients to Fedora 31. Over the past several days, we've discovered some odd behavior from some of the lab systems. Upon further investigation, we have learned that there is a kernel bug that is causing some systems to hang (requiring a reboot) when certain NFS operations are performed. (NFS is the system that allows our Linux clients to access the home directories, certain apps, other shared file systems.)
| |
| − |
| |
| − | ::We're seeing that the bug is documented and that it affects not only Fedora 31, but some prior versions as well. It just happens to be that we are seeing its effects now.
| |
| − |
| |
| − | ::This is a Linux kernel issue and there are Linux folk working on trying to get this bug patcMarch 22hed, but we do not know how long it will take.
| |
| − |
| |
| − | ::In the meantime, CS IT is looking into work-arounds to bypass this bug as much as possible.
| |
| − |
| |
| − | ::There is no way to predict if or when this bug will cause a system to hang. Some of our systems may never notice it. We think it might happen to some systems that are heavily utilizing NFS operations, but again, we're not sure.
| |
| − |
| |
| − | ::Our recommendation is that when you're editing files, etc. save your work on a regular basis, just in case. This is a good practice to follow anyway.
| |
| − |
| |
| − | ::'''''IMPORTANT:''''' If you experience a system that hangs (and doesn't recover after several minutes), please email {{mailto|support}} to let us know the name of the system that experienced the hang, the time of the hang, and what activity you were doing on the system at that time (which will help us troubleshoot the problem further.)
| |
| − |
| |
| − | ::We will update here with our progress on circumventing this bug.
| |
| − |
| |
| − | ::'''UPDATE: 1/29/20''' We are applying alternative pre-bug kernels to those Linux clients that are available to be rebooted (to activate these kernels.) As more become available, we'll reboot them as well. We're hoping these alternative kernels will prevent the hangups until officially patched kernels become available.
| |
| − |
| |
| − | ::'''UPDATE: 2/7/20''' We have applied updates to most of our systems in order to activate the alternative pre-bug kernels, which we hope will prevent hangups. There are still some systems which have not yet had the alternative kernels applied, and that will happen as the systems become available for us to reboot.

| − | '''8/24/16 1:30pm''' JHU's central mail servers are experiencing an issue that is causing mail bouncebacks for people not on JHU Exchange sending to people on JHU Exchange. An error might look like:
| |
| − |
| |
| − | :'''The reason for the problem: 5.1.2 - Bad destination host 'Multiple DNS'''
| |
| − | :'''queries were attempted and failed: DNS Hard Error looking up'''

| |
| − | | |
| − | JHU is looking into the problem at their end. Note that although the CS email servers are working fine, those on CS sending to JHU Exchange users may experience the same issue as others outside of JHU Exchange sending to JHU Exchange.

| − | ===Possible Email Bounces From Normally-Working Sites===
| |
| − | | |
| − | '''8/8/16''' We have been receiving reports of ''email bounces from people/organizations that normally work without problems.'' We think we know what is happening. We recently discovered that one of our CS student accounts had been compromised and was being used to send spam. Even though we disabled the account as soon as the compromise was discovered, several mail server reputation services had already classified us as a possible source of spam. As a result of that classification, some organizations have decided to temporarily reject email from our mail server. We can't predict ahead of time which organizations those are, since there are a variety of reputation services, and individual organizations differ in the ways they make use of reputation information.
| |
| − | | |
| − | This problem will fix itself automatically over the next few days, as the reputation services take note of the fact that we have stopped sending spam. There's no way to speed up this process, unfortunately.
| |
| − | | |
| − | This sort of problem doesn't often happen to us. But when it does, it causes headaches like the unexpected bounce messages some people have received. We will be implementing some new processes that we expect will allow us to react more quickly to situations like this, before they reach the point where other organizations stop accepting our mail.
| |
| − | | |
| − | We will update this page once the reputation scores have returned to normal.
