11-17-2023 06:00 | Use of "New Outlook" violates our use guidelines and law
Die LMU verbietet die Nutzung des E-Mail-Clients “Neues/New Outlook”. Dies betrifft alle Plattformen wie MS Windows, McOS, iOS und Android. Die Gründe liegen in datenschutz- und datensicherheitsrechtlichen Bedenken, sowie in einem direkten Verstoß gegen die Benutzungsrichtlinien der LMU, des LRZ und des IFIs.
Die neue Outlook-App überträgt Konto-Anmeldeinformationen zu Cloud-Servern der Firma Microsoft, ohne dass hierzu die eventuell notwendigen datenschutz- und datensicherheitsrechtlichen Voraussetzungen bestehen. Dies betrifft alle Konto-Anmeldeinformationen unabhängig davon, wo der genutzte Mailserver betrieben wird. Bei studentischen Nutzern liegt in jeden Fall ein Verstoss gegen die Benutzungsrichtlinien vor.
Des weiteren kopiert die App Mails, Kontakte, Termine und weitere Metainformationen in die MS Cloud.
Benutzen sie bitte andere Mailclients oder eine andere oder ältere Outlook Version, wo dieses Verhalten noch nicht implementiert ist.
Bei Fragen wenden Sie sich bitte an Ihre zuständige IT-Servicegruppe.

8-19-2022 15:00 | New TLS policies and features for mail and other services
The institute has decided to implement a more strict usage policy for current TLS versions for mail and other services. The policy up till now was to allow unsafe connections if one side did not support a secure connection.
Now all services will be successively switched to a stricter policy. This means that connections to or from us will only be accepted with TLSv1.2 and v1.3. Web connections will still accept http but will immediately reroute to https with secure TLS.
Users are advised to check if the software they use supports and uses secure TLS versions. There could be problems with the use of intermediary Software like mandatory proxies or ISP mail servers.
A further implemented change will be the usage of SPF and DKIM signing for mail. SPF is already active on most of our mail domains. The implementation of DKIM will be completed till the end of autumn. These measures can cause problems with mail forwarding.

This will impact the CIP-Pools Gobi (L U112), Sibirien (L U114) and Taklamakan (L U117). The PCs can become unreachable at any time during the maintenance window as well es lose access to fileservers and other services. SLURM jobs will most likiely crash. This will also impact the CIP IMAP Servers. These will be unreachable for some time. Spam tagging will be affected likewise.
Because the swaps also affect the building uplink the whole Oettingenstr. 67 will be unreachable for some time. This will lead to problems in Luna and Deneb. Homes, SLURM etc.

4-19-2021 12:00 | Aftermath of the big power fail at Oettingenstr.
Am ganzen IfI sind durch den Stromausfall in der Oettingenstr. Ausfälle an den IT Diensten entstanden. Teilweise sind auch Hardwareschäden entstanden. Wir versuchen alle Dienste schnellst möglich wieder in Betrieb zu bekommen. Infos zu Einschränken an Diensten an den LFE sind sicher auf den jeweiligen LFE Webseiten zu finden.
Aktuell - Stand 19.4 17:00 - sind im Bereich der zentralen Dienste für Studenten folgende Einschränkungen:
- /big ist akt. an den Arbeitsplatzrechner nicht verfügbar. Hier ist ein Hardwareproblem zu beseitigen. GEFIXT (19.4 19:00)
-
Studentische Mail ist nur eingeschränkt verfügbar. Durch ein subtiles Netzwerkproblem ist der Dienst nicht direkt per IPv6 erreichbar. Bei IPv4 ist das Problem nicht vorhanden, aber durch die Arbeiten an den fehlerhaften Loadbalancern kann es hier immer wieder zu Unterbrechungen kommen.
Als Alternative haben wir webmail.cip.ifi.lmu.de so umkonfiguriert, dass dieser Dienst direkt an allen problematischen Komponenten vorbei arbeitet. Hierfür war allerdings eine Änderung im DNS nötig, die, je nach Nutzer, eine bis zu 24 Stunden lange Verzögerung verursacht. Das einziges Problem das in dieser Zeit bemerkbar ist, ist eine kurze Verzögerung beim ersten Aufruf im Browser. GEFIXT (21.4 19:00)
Wir hoffen diese Probleme schnellstmöglich zu beseitigen. Sollte sie weitere Probleme bemerken, so mailen sie, wie immer, bitte an rbg@ifi.lmu.de.

11-2-2020 06:00 | 2.nd Update - Opening of CIP-Pools
We dont plan to reopen our CIP pools normally during WS 2020/21.
The reason for this decision is the configuration of the AC system for our rooms. At this time the AC system use only outside air and hence the temperature in the rooms will follow the outside temperature. This is bad for our IT equipment and a bad working condition.
We will restrict the AC system for our rooms and will reevaluate the situation in spring. Without an unrestricted AC system we cant reopen the rooms.

- you have to use a face mask
- you have to keep a safe distance
All other rooms will stay closed.

We will apply an update to gitlab on THU 30. July 2020 evening. This update will send Confirmation emails for registered email addresses in gitlab to some users. The reason for this is a bug in an older version of gitlab which allowed users to circumvent the confirmation of their email addresses until the bug was fixed. The current update sends the aforementioned confirmation emails to all users who could have used this bug. You need to confirm all email adresses registerd in your gitlab account to regain access to it.

6-15-2020 06:00 | New servers for CIP webmail

The old server will still be running for a few days after the 22. because it can take some DNS servers a few days to realize the move. For about 99% of all users the move should be done in under 10min. Please check profile changes a few days after the 22. and redo them if necessary just to be on the safe side.
It can take a few minutes for the new servers to be available during the move on Mo.

5-24-2018 10:00 | Neue RBG Website
The RBG has a new website.
There are several reasons for that:
-
The old website was no longer up-to-date. Especially for mobile devices with smaller screens.
-
It was past time to unclutter and restructure the contents.
-
The DSGVO which is now in force.
Sadly the last reason is a hard deadline. Which accounts for the contents not being as complete as we would have liked them to be. We will change this in the weeks to come.
4-1-2018 10:00 | Discontinuation of mail forwarding for @cip.ifi.lmu.de and @stud.ifi.lmu.de email addresses
From 1.10.2018 onward all forwarding of emails for recipient domains @cip.ifi.lmu.de and @stud.ifi.lmu.de ( and the corresponding long format informatik.uni-muenchen.de) to external mail providers will be discontinued.
All email sent to these addresses will then only be delivered to the local mailbox residing on the mailsystem of the IfI. The emails can be read there. The only exceptions will be forwards within the IfI and CIS.
Reason for this decision
There are tree reasons for this decision.
Fewer and fewer (external) mail providers accept forwards and a rising number have announced such actions for the near future. By accepting only emails sent directly from the owner of the originating mail domain they aim to achieve two results. Firstly this should improve the proof of authenticity of emails and secondly it should reduce SPAM.
Forwarding emails negatively impacts the reputation of our mail system. Mail providers use this reputation (e.g. through blacklists) to determine if SPAM might originate from our mail system. This can even lead to a complete rejection of all mail from our system. The reason for the negative impact is that all our anti SPAM meassures notwithstanding a small amount of SPAM still gets forwarded.
External mail providers sometimes reject mails from our system because of reasons like unknown recipient, mailbox full, technical issues etc. But a lot of our services are dependant on a functioning email reception.
What does this mean for me?
This change is not as bad as it first appears to be. Most good mail clients have a feature which transparently integrates mail from different mail accounts into one virtual mailbox. Just google for your mail client and terms like “unified inbox”, “unified folder” or “global inbox”.
