Mind the Server Maintenance Hours

Server Maintenance Hours are each Thursday, from 07:00-08:00. Also for HCM/Loga each Monday from 09:00 to 09:30!

During these times, server operation is unreliable. You should expect unavailable servers and sudden downtimes of services without prior explicit announcement.

See here for details.

  1. OK, I just experienced a weird networking error. In stead of the ususal 10.100 IP address I was assigned an IP address of the order 192.168 and my internet stopped working. On restarting the network countless times, I was finally assigned an IP address of the order 10.100 and it was only then my internet was functional. Experienced this problem on both Linux and Windows, and I am not the only one. Couple of friends had the same problem. Could you please illuminate as to what is the problem.

  2. Same Problem as Rahul's since last evening.


  3. Probably I am too stupid to find it. But I am missing a page introducing or just listing the IT team members with their fields of action (there has been such a page in former times before teamwork, hasn't it?). It might enhance communication, particularly if it is possible to match names and faces.

    Best, Ben

  4. I've a question concerning the mailsystem - is the whole server down or only parts of it, and when will it be fixed?

  5. Dear IT People,

    it seemed that there was an email outage (at least for the student email accounts) from March 8th in the late evening until thins morning March 10th (when I guess with the start of the business hours the problem obviously got fixed by you). While I agree that problems occur and that some downtimes for a period of 1-2 hours might be unnoticeable I find it a bit frustrating that the whole university cannot use email for more than 1 day. It is also true that it was Sunday yesterday but the Nagios system was reporting a critical IMAP/POP3/etc service already on Saturday night .....
    I cannot find any information about this >1day downtime so this is why I am writing here asking for information, please point me to the proper place if I have overlooked it. And maybe a question - can something be improved in the direction of 24/7 IT support (I mean for the important services such as network connectivity, email etc) since a downtime of 1 day even on Sunday is very frustrating for the people who rely on email for their daily tasks?

    Thank you very much for your information and response in advance!


  6. Sorry to post this here, but I haven't received any answers to my emails or requests.

     I have the following problem: about 3 weeks ago I went to student IT support because my DELL laptop battery was causing problems. The student there called DELL support and they told him they would send a new battery and that he should apparently keep the old one in the office so that it can be returned immediately after the new one arrives. I was told to come after 2 days to pick it up, but nobody was in the office at that time. I have tried on several occasions to get my old one, but it is still locked in the Student IT Support office.

     I contacted the student in charge on several occasions: he refused to call DELL and ask what the problem is even after a week, he refused to give me my old battery and now he is off campus, so he said he cannot do anything about it. I cannot call DELL myself since I don't have access to the old battery anymore.

    Is there anything somebody can do to help me in this matter?

    Thanks a lot,


  7. Hi,

    is there a way to access the university email with WAP? I tried but it is kind of broken. Are there any other ways?


    P.S. Sorry I posted this at the wrong place the first time ..... also it looks like I cannot delete it from the blog

    1. Right now we do not provide a possibility to access webmail via WAP.



  8. Hi,

    I have a question regarding malware protection on the Dell computers purchased from the university.
    I've been running the Symantec Antivirus program that was installed on the laptop for almost a year now. I was recently irritated, however, that the program "Windows Defender" was turned off all the time. When I turned it on, Symantec didn't seem to update its definition files any more, when I turned it off, it updated them again. Do the programs interfere in any way that necessitates turning Windows Defender off? Which setting would you recommend to ensure the highest degree of security possible?

    Thank You,

    1. Has been answered in Ticket #2008090510000521.

  9. Hello,

    Teamwork seems to be down every Sunday (or at least it was in the past two weeks, which is when I returned on Campus). Now that the course forums are on Teamwork, this is a pretty annoying issue. Is there something special with Sundays (should we expect the site to be down?) or was it just an unfortunate coincidence?


  10. Dear Mr. Schmidt,

    the Jacobs internet to the outside world has witnessed quite some troubles these past days, which manifest themselves in interruptions of the internet connection, concerning from my experience all websites and messengers including skype. As such it would be great if you could look into that, because it is not only annoying, but literally not part of the service that we as students should be able to expect.

    Thank you in advance for your help and best greetings,

  11. Dear Mr. Schmidt,

    In the last couple of days we've been experiencing a weird failure in the DNS servers on campus. This happens not only in the colleges, but also in the wireless network.
    Whenever I try to access a .bg internet site, the DNS is unable to resolve it. Surprisingly, after a certain number of retries the site just appears in the DNS. Weird.

    C:\Documents and Settings\Teo>tracert
    Unable to resolve target system name

    C:\Documents and Settings\Teo>tracert

    An experiment with google.XX showed that there is such a problem at least with .cz (no problem with .ro, .sk, .pl, .gr, .rs, .de, .com, .org)
    Quite annoying. Can you do something about this, please? (smile)


    1. Thanks for your investigation! I can reproduce the issues. Submitted as ticket# 2009042710000694.

      1. Issue solved. Thank you very much.

  12. Hi,
    I have the same problem as Teodor and all people interested in opening .bg pages! If it is something that can be fixed, please do so, because this is really creating trouble for us (like not being able to open important emails etc.)
    Thank you very much for your help!
    Have a nice day,

  13. Is there a reason why the course catalogue for Spring 2010 is not uploaded on the website or campus net yet? On the website it said it would be available 15.01.2010. I am not sure if this is a problem on the side of IT or Academic Affairs, but I just wanted to check. Also on teamwork it says it will be complete by December 4:

    Any information would be helpful.

    1. All systems appear to work fine from a technical perspective.

      Can't tell for the content...

    2. It should be available now.

  14. The content is the actually managed by the registrars office in this case (course catalog to be particular). It should be up very soon (hopefully).

  15. Just got a very interesting e-mail, presumably from "Jacobs". Posting header + content here, maybe it will help setting up a spam rule:

  16. Hi,

    Im experiencing problems with the internet connection through the hotcakes page.
    I dont have VPN working on my computer now so I can not try if that would work. I can access all internal websites, but when I go to external and try to log in for unsecured access I get a log in failed. My log in is not blocked since I can log in on teamwork and campusnet.
    Is there some maintenance going on and will this log in issue be fixed soon?

  17. Hi,

    It seems that receiving e-mails is not possible?! After wondering about the little amount of spam we received today a friend and I tried sending messages to each other and they're not coming through. Sending e-mails to non-Jacobs accounts works fine.

    Any ideas?



  18. Hello,

    I do not receive messages from CampusNet on my e-mail anymore (Outlook), although the respective setting exists on my CampusNet account. Can anything be done in order to solve this problem?

    Thank you,

    1. I just sent a test mail to your CampusNet account; report to if you do not receive this also in your Unimail account.

  19. I can't access my mailbox anymore (neither in Thunderbird or in the web app). It started Wednesday on Thunderbird, but for short time. Since this morning I can't access anything at all. The errors that I now have are: "Login to server ... failed. Retry/Enter New Password/Cancel" in TB and "Your mailbox appears to be unavailable. Try to access it again in 10 seconds. If you see this error again, contact your helpdesk." in webmail.

    I previously had the IMAP problem when I was retrieving the emails from the server with Thunderbird.

    1. Same here! I hope we won't have to wait until Monday to have it fixed?

      1. This is another "me too" message. Useless in itself, but: I would appreciate if someone could also take care of such things during the weekends. At least by saying: "Yes, we have a problem, and unfortunately you'll have to wait until Monday."

    2. exactly the same problem for my account - since yesterday evening, doesn't work in TB or the webpage.

  20. I have the same problem with both Thunderbird and the web app
    I didn't change anything in the server settings and since last night I cannot access my mailbox at all.

  21. I have the same problem!

  22. Me too. It says "Your mailbox appears to be unavailable. Try to access it again in 10 seconds. If you see this error again, contact your helpdesk." So, what's going on?

  23. same here no access to email at all..... is there anyone we can call about this? especially if you have time-sensitive stuff there that needs to be done today...

  24. By now it is clear that this is a university-wide problem. I strongly support the suggestion for having a resident support officer during weekends as well, as many crucial tasks go through our mail accounts these days, throughout all 7 days of the week.

    1. And it turns out that not only have we no access to the mail, but also it is impossible to send mail to Jacobs mailboxes meaning that some important messages may not reach us at all...

  25. I get all my Jacobs emails in Gmail, and I had no problems receiving or sending emails from there (using my Jacobs address, of course).

    I can also send/receive emails from/at

  26. Sorry for the glitch last weekend! The situation was resolved by IT staff at around 7pm on Saturday. Here's the announcement to that effect:

  27. About 3 hours ago I was working on CLAMV (tlab062, ssh-ed from outside the campus using the IP) and received a message saying:

    tcsh% Broadcast message from root@tlab062 (tty1) (Thu Apr 21 10:28:05 2011):

    The system is going down for system halt NOW!
    Write failed: Broken pipe

    It logged me out, and since then I haven't been able to log back in. Every time I try I get a "Connection timed out" message.

    Is there another way to connect to CLAMV from outside the campus?

    1. tlab062 is down due to a damaged Power supply unit
      wich will be replaced on Tue. 26th.
      You can connect to the other CLAMV Computers using a VPN
      connection to the University Network or you can use a ssh session to
      and connect from there to the CLAMV Computers.

  28. Is there something wrong with the Exchange email server?

    Since last night at about 1am I have not received any email and by trying to test with a different email account (by sending to the Jacobs one) I have received a "delivery delayed" notification. I have also checked if my inbox is full and it is not the case. I am waiting for some very important emails and I would really appreciate receiving them in due time.

    Thank you,
    Mihai Cirlanaru

    1. All is well. Ref:[Ticket#2011051711000114]

      How do you use Exchange? Did you try the web interface at

  29. Hello,
    I have the follwoing error msg when trying to access my email
    Your mailbox appears to be unavailable. Try to access it again in 10 seconds. If you see this error again, contact your helpdesk.

    it is since yesterday evening,,,


  30. Hello,

    I have a problem with my email account. I can open, read my emails, write an email, but NOT send it. On Thunderbird, I can send emails to individuals, but not lists.

    This is the message I receive only on Thunderbird:

    An error occurred while sending mail. The mail server responded: 5.1.3 Invalid address. Please check the message recipient and try again.


    1. What is the email address you are trying to send to?

      1. I have the same problem, it does not work with any e-mail addresses

        1. Can you post a screenshot of the email sending dialog (including the destination email address) here to have a look at?

            1. There is a small inverted rectangle to the left of the "This message hasn't been sent." message. Can you click on that to open an associated info box, and provide the message given there?

  31. Hello,

    The internet in my room stopped working last evening. It says it might have used peer to peer or violated any rule. The strange thing about that is that I was not in my room at that time and my computer was not turned on. So when I came back from Common Room around midnight there was this IRC-IT message that my internet access has been blocked. The message says that I would get a notification via e-mail but I have not.
    I would like to drop in today at around 3.30 pm. I cannot make it before because I have to go to Economics lecture. It would be even better when the problem could be fixed before somehow. Please reply to this message.

    Many thanks in advance.

    1. Please contact IT support via regular channels, see Service Desk for Faculty and Staff.

  32. I just sent an e-mail to <> and received the following automatic reply:

  33. Still I cannot connect to eduroam by Androide Phone. Any Idea ? 

    1. Please have a look at our HowTo's for configuring eduroam:

  34. I cannot seem to find this, where are instructions/FAQ on what happens/what steps to take when you leave the university?

    (In terms of what happens to the email address, and whether or not you can forward to another address, e.g. alumni one)

    1. That's asked during the exit process as done by the Student Records dep. We are currently handling this the same as for employees as described in Richtlinie zur Nutzung von Informations- und Kommunikationsdiensten (ICT Guideline): you can set a forward, that might get removed after six months.

  36. I cannot login into CampusNet.

    Is this just an ordinary capacity overload?

  37. Hello, since a  few days I cannot edit any content in Teamwork anymore. I am off campus but am using VPN, can anybody help me solve this problem?
