Due to an unforunate failure, the RAID filesystem had to be recovered from backup. This means that the system will be rolled back to the date of the last backup, in this case Sept 26 due to unforeseen circumstances. At this moment, all messages received from the period between the backup and the crash will be lost. We will continue to try to recover as many data as possible.

On saturdaymorning between 05:48 en 10:48 all FNWI netwerk services were unreachable due to a failure of one of the WCW switchmodules.

The problem has been solved at the moment and will be investigated.

Due to filesystem problems, the FNWI e-mail services are temporary unavailable. hosts affected: mail.science.uva.nl imap.science.uva.nl smtp.science.uva.nl
Update: 13-12-2006 19:00 The problem has been solved.

Due to filesystem problems, the FNWI e-mail services are temporary unavailable.

hosts affected:

mail.science.uva.nl imap.science.uva.nl smtp.science.uva.nl

Update: 26-10-2006 08:00 The problem has been solved.

For further stabilisation of the E-mail service maintenance has been planned.

On Monday July 3rd 2006, starting at 16:00, the FNWI E-mail server will become unavailable. It is expected that work will be finished before 23:00.

In this period you cannot read E-mail (nor receive) on the FNWI E-mail servers (including 'webmail'). The E-mail protocol takes care of normal operation. _No_ mail will be lost.

In case of problems afterwards you can get help in the normal way: via the _support_ pages or an E-mail to support@science.uva.nl with the subject [emailproblems]. You will be helped with higher priority.

Update 21:00 : finishing time changed to 23:00

Update 23:00 : maintenance finished; mailserver is up and running

This morning the WTCW-fileserver for the STAFF-domain was rebooted due to hardware failures of the raid-system. Around 9:00 the server is operating normally. During the problem some services were unavailable (logging in, network-drives, printing).

The mailserver experiences more than usual workload, and cannot handle all connections. Therefore some connections to FNWI computers are rejected which causes local mailprograms to complain.
We are working to find a solution.

Due to a hardware failure today (raid system) the email server is down. These problems also caused problems on the wtcw-server. It's uncertain how long this will take.

On january the 12th, thursday, all ict members are invited to join the meeting of the new IC.

The E-mail server imap.science.uva.nl uses the new disk.

For further stabilisation of the E-mail service we have maintenance planned. To minimise any adverse impact this is planned during the Xmas reces.

On December 27th 2005 at 10 am the FNWI E-mail server imap.science.uva.nl will be brought down for several hours. We expect to be in working order at 3 pm.

In this period you cannot read E-mail (or recieve) on the FNWI E-mail server (including 'webmail'). The E-mail protocol takes care of normal operation. _No_ mail will be lost.

In case of afterwards problems you can get help in the normal way: via the _support_ pages or an E-mail to mailto:support@science.uva.nl?emailproblems with the subject emailproblems. You will be helped with higher priority.

Due toe hardware problems unscheduled maintenance is required.

2005-12-13 19:15. End of maintenance

Due to a hardware failure last night (raid system) the email server is down. These problems also cause problems on the wtcw-server. Some people cannot log in because the shares wtc8, wtc10 and wtc12 are not available.

It's uncertain how long this will take.

*EDIT: 13-12-2005, 09.00 servers up again.

Due to a hardware failure this early morning the wtcw-server id down It's uncertain how long this will take.

Due to an intermittently failing fiber-optic connection between the WLAN switch and the core router, there are periodic outtages of the wireless network at the Kruislaan 403 (F-Building).

We are trying to get the cause diagnosed and fixed as soon as possible,

Sorry for the inconvenience,

With kind regards,

The ICT Group FNWI (ad interim)

Tonight a raid partition on the WTCW server (filesystem wtcw20) has broken down due to hardware failure.

The problem affects most users on the REC campus. The site natuurkunde.nl is also unavailable.

13:00 23/06. The raid system has too many hardware problems. Therefore a spare raid is being set up, and backups will be restored from tape. Note that this will take at least 24 hours!

Due to a problem with one of the Surfnet routers, the internet is temporary unreachable.

The faculty wide migration of the Linux hosts to Fedora Core 3 is almost complete. We have migrated 198 out of 225 targeted hosts (A number of hosts used for educational purposes will be switched after the trimester). The hosts that remain to be migrated are:

ampere, boyle, celsius, cimex, den, epe, equator, euler, eulogia, fama, faraday, joule, kelvin, marquez, moebius, nics, odin, papaya, pascal, plus, recordame, snoopy, squid, tetrode, thebe, tintin, young

Unfortunately, these machines need to be repartitioned and therefore will lose the content of their scratch partitions.

As you will remember, the contents of scratch partitions is not actively backuped in any way by the ICT Group. Therefore, if you have data on the scratch of any of these machines, it is important that you save it yourself _before_ the migration.

We repeat:
Any important data on the scratches of the above hosts should be moved to a save location (and put on backup) before wednesday, june 1st 2005

With kind regards,

The FNWI ICT Group [ad interim]

We've found that certain fields in the new CA-certificate weren't filled in correctly. This could adversely affect your ability to connect to the FNWI WLAN. (Symptom: openssl reports error 20 at 0 depth lookup:unable to get local issuer certificate).

Using the CA-certificate from the link below should fix these issues.

Due to security-measures the accountview server has been taken off-line pending an upgrade to the Windows Server 2003 operating system.

In the course of today (thursday april 7th 2005) it will come back online.

We apologise for the inconvenience,

ICT Group FNWI (ad interim)

-----------------------------------------------------

[07-04-2005 12.00 status update]

The server has been reinstalled with Windows Server 2003 SP1 and is online.

ICT-SNB

The network-equipment in the Matrix 4 building will be adjusted. From friday february 11th 2005, 17:30 hrs until monday february 14th 2005, 09:00 hrs, network connectivity may fail for workstations in the Matrix 4 building

Sunday, February the 13th, the ICT-group will disconnect the network-equipment and re-connect it. To facilitate this, the core network equipment in Matrix 4 needs to be reconfigured. The latter will be done on friday february 11th, 17:30 hrs.

To prevent loss of data, we ask that you leave your computer ON, but logged of.

If you encounter problemens, please E-mail to 'support' with the subject of "Matrix 4 patch problem". These calls will receive priority treatment.

Some time ago, HP-printers have been placed along side the existing printers on the ground, 1st and 2nd floor of the AH-2 building. These new printers can be taken into use after an update that is planned to take place in the upcoming weekend.

A new printer has been placed on the 3rd floor that replaces the old lexmark printer. This lexmark printer has been removed because of a shortage of space.

Planning and actions ICT group

The pc-s that are under ICT-Group maintenance will receive an update this weekend (providing that the pc will remain switched on and that it's user will be logged of).

During a short period of time, the old and new printers will both remain operational. However you are requested to start using the new printers as soon as possible.

What you can do

The (new) name of the printer you want to use can be found on a label that is placed on the printer.

Users of ICT Group serviced laptops are requested to contact us for an update. (mailto:support@science.uva.nl).

Apple

User of a Mac system can find a manual that explains how to install the new printer driver (sorry dutch only) here.

Should you not be able to perform the installation, you can send an email to mailto:support@science.uva.nl .

Linux and MS Windows

Self maintained Linux and MS-Windows computers will need to have the configuration modified to print through print-queues that are provided by the wtcw-server.

Effects on "old" configurations

Since year and day the FNWI makes use of printserver to offer print capabilities to client applications ("printing programs").

In older configurations it can occur that it makes direct contact to a printer. This was never supported by the ICT-group and now with the introduction of the new printers, it is technically impossible.

Specifically this means that every configuration that contains settings that specify direct access to a printer, will have to be adapted. In the current state they will not work with the new printers.

In case you experience difficulties

In case you experience difficulties that you find to be in relation to the introduction of the new printers, we ask you to report this as soon as possible through a job with subject: [PRINTERDIFF AH2].

The email adres of the ICT service-desk is: mailto:support@science.uva.nl

These jobs will recieve priority treatment.

With kind regards,

Dear colleagues,

Monday October 25th, starting at 17:30 hrs, there was some maintenance to the server-infrastructure of the FNWI.

This has been completed as planned.

With kind regards,

Dear colleagues,

Monday October 25th, starting at 17:30 hrs, there will be some maintenance to the server-infrastructure of the FNWI. This because of work that needs to be done to the core storage infrastructure in order to improve overall stability.

In the course of this maintenance there will be long outages of file services. Please logoff before we start in order to prevent data loss.

Of course the FNWI ICT-Group will do its best to minimise any inconvenience to the best of its abilities. It is expected that work will be finished before 21:00 hrs.

With kind regards,

Due to some network equipment problems the following fileservers were temporary unavailable:

imap.science.uva.nl (mail.science.uva.nl), smtp.science.uva.nl, webmail.science.uva.nl, remote.science.uva.nl, sremote.science.uva.nl, student.science.uva.nl, wtcw-server.science.uva.nl, carol.science.uva.nl gene.science.uva.nl, init.science.uva.nl

The problems have (temporary) been solved.

On tuesday september 7th 2004 the core network connection of the buildings Mauritskade 57 and Mauritskade 61 will be upgraded to a fiber-optic connection.

Unfortunately to accomplish this, it is necesarry that there will be a disruption of UvANet/internet connectivity in these buildings from 16:00 hrs to 17:00 hrs that day.

Ofcourse the upgrade will result in faster connections to the UvANet/internet in these buildings.

Due to Raid problems the Mailserver and the Staff Fileservers are down.

Tomorrow morning 10 Aug there will be maintenance on them.

Regards, Systems Manangement

On monday august 9th, we have to do some mainenance on the FNWI network which will result in downtime from 16:00 hrs. to approx 22:00 hrs.

In the past we have experienced server-outages due to failure of the power supply system in the main serverroom at the WTCW during peakconditions. As reported earlier we have to take provisions to prevent this from happening in the future.

On monday august 9th, the ICT-Group plans to replace the underperforming power-automatas with new ones that will be able to handle higher peak loads.

As you can imagine, this is quite an operation so we have to reserve some time outside the regular maintenance window to be certain we can complete the operation on monday.

This means that on monday august 9th you will not be able to access the FNWI network from 16:00 hrs until work is finished (hopefully before 22:00 hrs)

We apologise for the inconvenience

It has been reported to the ICT-Group that a large number of new computer viruses that spread through ZIP-attachments is going around.

Although the anti-virus systems on the mail-servers probably will intercept most viruses, it is possible that some will slip through.

Hopefully completely unnecessary, we strongly advise not to open any attechments from which the origin is unclear.

Thank you for your cooperation,

--JR

This evening (july 9th, 2004) we will upgrade our webmail software to a new version. This version introduces, aside from the usual bug- fixes, the following improvements:

• Performance, this version should be faster than the previous.
• Appearance, most people find this version to be better looking.
• Better security during use in internet cafes.
  Many webbrowsers have a "feature" that facilitates storing the content of forms for later use. In public venues this can lead to undesirable situations. Someone that uses the computer after you, should not have access to data you filled in on some form on the internet.

  The new software now tries to prevent this "storing of form data".

Planning and steps taken by the ICT Group

This evening (july 9th, 2004) the webmail software will be upgraded. This means that the webmail service may be interrupted for a short period of time.

If you experience a problem afterwards

The upgrade should, apart from the short interruption of service, not have any negative effect on your use of the webmail service.

In case you do experience a problem that you think is related to this upgrade, please send an email to support@science.uva.nl with as subject:
WEBMAIL upgrade

These calls will be given priority treatment

During the regularly slotted maintenance service-window of monday June 14th, starting at 18:00 hrs, there will be some extensive maintenance to the server-infrastructure of the FNWI.

In the course of this maintenance it is possible that there will be longer or shorter outages of e-mail and file services.

Ofcourse the FNWI ICT-Group will do its best to minimise any inconvenience to the best of its abilities. It is expected that work will be finished before the end of the maintenance window at 20:00 hrs.

As a consequence of the power-failure of tuesday we need to bring the server systems down and up again. This will not take long but there is a possibility that certain services will be inaccessible to you for a short period of time on thursday morning before 09:00 hrs.

With kind regards,

OK, It's one of those days ;)

Whilst trying to diagnose a problem on a certain subsystem in the RAID-enclosure there was a powersurge that overloaded the fuses and rendered a largepart of the WTCW server park in an inconsistent state.

Needless to say we are in the process of bringing these servers back up. We expect to have everything up and running within an hour or so.

[UPDATE 18:36] It's _really_ one of these days. We've encountered serious filesystem errors on the imap-filesystem. This will take a _long_ time to rebuild and until then you will unfortunately not be able to access your email.
--JR

[UPDATE 00:57] We finished the rebuild of the filesystem. We had some sparse errors so if you are the unfortunate soul who has lost some part of your mailbox, please contact support@science.uva.nl

We should be up and running now ;)

[Post Scriptum 02-06-2004 12:00]
Ofcourse we have done some post-crash analysis on why/how this has come to pass. We have found that the powerbricks that supply the RAID systems performed far under the specified norm (i.e. they are defective ;)). These have been replaced, but maybe we will have to do maintenance on the total powerrail system in the server-room in the future. Ofcourse when this is the case, you will be informed accordingly.
--JR

This morning we experienced a large number of inconsistencies on certain hard-disks of the RAID-system of the rec-server.

To repair these, we needed to take the rec-server off-line for a period of time, which resulted in down-time for the users which have their home-directories hosted by the rec-server.

The repairs are now completed and operations have returned to normal

We apologise for the inconvenience,

With kind regards,

Microsoft has released a number of critical patches to address some serious vulnerabilities. Therefore all Windows systems, which are maintained by the ICT group, will be updated and rebooted tonight. For tonight: please log out of the system (no system shutdown) and turn off the monitor.

Involved operating systems: Windows NT4/2000/XP. For more information about these vulnerabilities:

http://www.microsoft.com/security/security_bulletins/200404_windows.asp

Today mutt version 1.5.5i was installed on both Linux and Solaris platforms. This version has better mime type handling and fixes a problem with long aliases (which could cause a bus error).

Mailserver has crashed at 14:00 hour this afternoon. Probably a hardware failure. Emergency repair is going on.

Machine will be up as soon as possible.

During the regularly slotted maintenance service-window of monday March 22nd, starting at 18:00 hrs, there will be some extensive maintenance to the server-infrastructure of the FNWI.

In the course of this maintenance it is possible that there will be longer or shorter outages of e-mail and file services.

Ofcourse the FNWI ICT-Group will do its best to minimise any inconvenience to the best of its abilities. It is expected that work will be finished before the end of the maintenance window at 20:00 hrs.

The flux migration-project has been completed.
Please report any problems resulting from the migration to support@science.uva.nl or the local servicedesk.

For your information:
- windows profiles could not be migrated; some personal settings need to be redefined.
- on the rec-server diskspace per user is limited by quota.
- data on rec-sever is also available through "ssh remote".
For those computers not maintained by FNWI-ICT, that are using name-services from flux, the following settings need to be changed:

DNS-server : primary   146.50.6.24
             secondary 146.50.4.70
WINS-server: primary   146.50.15.103

Recently a new virus called "Bagle" has become active. The virus send mails with an encrypted attachment and lists the password in the message text. Since the attachment is encrypted our anti-virus cannot detect and eliminate the virus and the mail INCLUDING the virus is delivered in your mailbox.

Mails with the new virus are oftem signed with variations of

Best wishes, The Uva.nl team http://www.uva.nl

and appear to be sent from addresses such as:

staff@uva.nl support@uva.nl administration@uva.nl management@uva.nl

None of these addresses are regularly used in the UvA. If you see a message from any of these addresses, delete the message immediately.

The addresses listed above were added to the blacklist on the FNWI mailserver.

During the regularly slotted maintenance service-window of monday March 1st, starting at 18:00 hrs, there will be some extensive maintenance to the server-infrastructure of the FNWI.

In the course of this maintenance it is possible that there will be longer or shorter outages of e-mail and file services.

Ofcourse the FNWI ICT-Group will do its best to minimise any inconvenience to the best of its abilities. It is expected that work will be finished before the end of the maintenance window at 20:00 hrs.

A new email worm called MyDoom or Novarg has been reported as being in a state of "aggressive propagation". The worm infects MS-Windows computers on which mail attachments are automatically (Outlook, Outlook Express, Eudora) or manually opened.

The antivirus system on the FNWI mailserver was updated to block the worm as soon as new virus signatures became available, thus the FNWI mailserver is immune to the worm and will zap messages containing it. Furthermore all machines which are managed by the ICT-Group have received appropriate upgrades to the anti-virus software and should be able to detect this new worm.

As always we kindly request that you are careful when opening unknown email attachments, since there is a probability that you activate a virus/worm in doing so.

As part of the extensive project of adapting the FNWI ICT Linux configuration system to deploy Redhat Linux 9 installations, we are currently running trials with a selected number of users.

The object of these trials is to find out if our configuration meets the needs of our diverse user base, and to fix any problem that hasn't surfaced during the preparation phases.

As a result of these trials we have found that the Linux 2.4 kernel that we initally deployed is unstable under certain loads. As a consequence it has been decided to push forward the introduction of the new Linux 2.6.1 kernel. Not only is this kernel more stable than it's 2.4 counterpart, we think you will also find it to be more responsive.

Barring unforeseen issues, we hope to be able to end the trialphase within one month. Please keep a watch on this page for information about the eventual faculty-wide introduction of Redhat 9.

Dear colleagues,

Due to mechanical problems, the mail server needs to be shutdown.

The repair will take approximately 15 minutes.

If you experience a problem which you think is related to this
update, please contact support@science.uva.nl with the subject-line:
MAILSERVER SHUTDOWN. These messages will be given priority treatment
by the support staff.

With kind regards,

Dear collegues,

Some of the linux machines experienced hangups. Furthermore recently, a few security related issues have arissen. To solve these we need to install a critical kernel update. This requires a system reboot.

The kernel update will be installed today (Monday januari 12th) between 22:00 and 23:00.

Because of the this, all processes that are running at the time of the reboot will be killed, including login sessions.

If you experience a problem which you think is related to this update, please contact support@science.uva.nl with the subject-line: KERNEL_UPDATE. These messages will be given priority treatment by the support staff.

The migration to the new mailserver yesterday evening (December 15th) was successful.

Only a few users using Eudora as a POP3 client encountered the problem that Eudora was not able to handle the new SSL certificate for the mailserver. The ICT group has turned off SSL support for POP3 on the mailserver as a temporary solution.

The last weekend our faculty web server started giving hardware problems. It became impossible to surf www.science.uva.nl and other pages hosted here.

This machine is now replaced.

MS-Windows users may have had a mount on this machine (/home/web). This must be remounted (usually logout/logon does this).

If you still encounter problems please contact us by E-mail to 'support' with in the 'SUBJECT' field "problems with web-server", we will pay extra attention to this.

A new Windows virus was discovered last week. This virus propagates through email and supposedly originates from "Microsoft Corporation Progam Security Division" and is sent to "Microsoft Corporation Client".

The contents of the email invites you to install a September 2003 security update."Microsoft Corporation Client".

When you receive such an email delete it immediately. Security updates are installed by the ICT group, not by ordinary users. Furthermore, Microsoft never sends updates through email.

The FNWI mailserver and centrally managed desktop systems are immune to the virus; your personal laptop however, may not be immune.

New version of maple is available. Maple 9.

Linux and solaris: The software is now available under linux and solaris.

Edit your ~/.pkgrc file. Put "maple9" or "maple" in your ~/.pkgrc file. To use maple8 use "maple8" in your ~/.pgrc file.

Windows: Pc's with maple and mathematica installed on it will automatically be updated. This concerns ict managed pc's only. If it's not installed already. Sent a email to support for installation.

Home use: Maple may be used at home. The latest version will be available at the libraries soon. This cd contains windows, linux and MacOS X. See also: https://www.science.uva.nl/ict/FAQs/faq.CGI?id=59

Mathematica 5.0 is available.

Linux and solaris: The software is now available under linux and solaris. Edit your ~/.pkgrc file.. To use mathematica5.0 put "mathematica5.0" or "mathematica" in your ~/.pkgrc file. If you still want to use version 4.2 use "mathematica4.2" in your ~/.pkgrc file.

Windows: Pc's with maple and mathematica installed on it will automatically be updated. This concerns ict managed pc's only. Sent a email to support to get it installed if it is not yet installed.

Home use: Maple and mathematica may be used at home. The latest version will be available at the libraries soon. This cd contains windows, linux and MacOS X. See also: https://www.science.uva.nl/ict/FAQs/faq.CGI?id=49

By removing the Shutdown button the ICT Group wants to encourage users to leave their Windows PC's turned on at night and during weekends. See also the Update page.

At night and in the weekend the ICT Group installs updates on Windows PC's. Among these are the updates for antivirus software. Regarding Windows viruses and worms the past summer was extremely hot and the updates were proven to be very necessary. Not only for your Windows PC but also for the ones used by your collegues inside and outside the faculty.

So please leave your Windows PC turned on at night and during the weekends and do logoff. If you want to save energy, you may turn off the monitor.

If your PC is turned off during the weekend, no updates can be installed and the possibility is very real that withing minutes you switch your PC back on it is infected by a virus or worm.

Restarting a Windows PC If you must restart a Windows PC, you'll find a button to do this in the login screen.

Virus W32/Sobig.f worm outbreak under control  -  Tuesday August 19th 2003, 15:00.

A new email worm was discovered worldwide around 12:00 CET. The worm infects Windows computers on which mail attachments are automatically opened (Outlook, Outlook Express, Eudora).

About 10 Windows systems at FNWI were infected an cleaned by the ICT group. The FNWI mailserver has a rather high load because it has to scan much more incoming email due to infections elsewhere on the internet. The antivirus system on the FNWI mailserver was updated to block the worm as soon as new virus signatures became available (around 15:00 CET).

If you receive a mailmessage with an attachment and the message itself only contains the text "Please see the attached file for details." delete the message immediately. DON'T open the attachment.

The FNWI mailserver is immune to the virus and will zap messages containing the virus.
