Accounts

Ask for/request/create account in the following order:

  1. Linux cluster account: ask Physics IT support. The Inst. 3 IT Twiki provides useful information about many many topics new students are confronted with in their first days at the institute 3b
  2. CERN registration check below or CMS twiki
  3. Grid certificate or GridKa webpage - Master or PhD students only
  4. Optional NAF@DESY account or NAF official webpage

It makes life easier if you try/insist on getting the same username everywhere.

Further accounts needed:

CERN account

  • Ask an authorized person to initiate the registration process for you and wait until you get a response via mail.
  • Fill out the Home Institute Declaration (HID)
  • Send HID and a copy of your passport/ID to an authorized representative of our institution.
  • Contact the IT-Service Desk via e-mail ([email protected]) and ask for a login-name and a temporary password (you might have to send a copy of your passport or personal ID again).
  • Change password immediately and pass the Computer Security Course.
  • (For this step you need a CMS account.) Contact CMS Computing via e-mail ([email protected]) and ask them to add your account to the zh group as well as the egroup cms-web-access to be able to access certain TWiki/Indico pages.
  • For Bachelor/Master students, who are no authors in CMS: In order to access all indico events, contact your team leader and set the flag Physics Exception for you! This grants access to certain indico events/meetings (e.g. Higgs to Tau Tau end of the year meeting).

CMS registration

  • IMPORTANT: You can register at CERN only if you have a valid CERN contract
  • Fill out registration form at iCMS and send a copy of your passport or personal ID (the link may does not work. See: Next steps.)
  • In case the above link does not work send an e-mail to the cms.people(AT)cern.ch. They will send you new links to fill the registration form and to upload a copy of your personal ID or passport. (Safari does not work properly to fill the registration form!)
  • or follow these steps:

In order to get registered into CMS:

STEP 1: Upload a copy (scan) of your passport or official identification document, using the link (the link is secure as it is using https) (use enough scan resolution in order to get it readable by the secretariat) https://cms.cern.ch/ident/scanUpload.cgi?scan_key=SOM44Z88XS

STEP 2: Fill in the registration form, using the link http://cms.cern.ch/iCMS/admin/newregistration?key=SOM44Z88XS

The form will then be forwarded (for acknowledgement) to the team leader of your institute.

(PLEASE NOTE THAT THOSE TWO LINKS SHOULD ONLY BE USED BY THE SAME PERSON.)

  • Wait for approval by your team leader or your deputy team leader.

Grid certificate

Master or PhD students only

  • Apply for a Grid-Ca certificate here.
  • As soon as you receive your certificate, look through the following pages for exporting your certificate as well as converting it: ** Export ** Convert
  • Create a directory called .globus in your home directory and move the usercert.pem and userkey.pem(exactly this names!) in there and set the rights as follows:
chmod 400 userkey.pem
chmod 644 usercert.pem

VO registration

In order to be able to submit jobs to the grid, you need to become a member of the CMS Virtual Organisation (VO). Following the TWiki page, this should be no problem. For simplicity, you might want to use the same e-mail address you were using for getting your gridka-ca.

If you completed all the steps for converting your certificate, the command voms-proxy-init -voms cms -debug -verify should work and you are now able to use the grid.

NAF@DESY account

If you don't have a DESY account

  • Follow the instruction at NAF under the section Member of another German university or institute?.
  • Fill the form and submit the request.
  • Once you receive the email of the activation of your account, change the password (command passwd).

If you have already had a DESY account

  • Send your user name at DESY and your previous group to naf-helpdesk(AT)desy.de by specifying your new group(CMS) and stating that you would like to move your account to af-cms namespace.
  • You can also keep your access to your previous group, if you need. Explain the situation in your e-mail.

For more information, see CMS TWiki Page (you will need to have a CERN account for this).

Mailing Lists and Other Communication

Request to be subscribed to the following mailing lists:

To get subscribed to the mailing lists hosted at KIT send a mail with the subject subscribe LISTNAME YOUR NAME to [email protected]. The listname in always the first part of the corresponding email address (before the @). Sending these emails will notify the list-admins of your request and they will act accordingly. You will get a confirmation of you subscription as soon as it is accepted.

Additionally, you might consider subscribing yourself to relevant topics of CERN Hypernews after you obtained a CERN account and after you created a separate Hypernews account.

Thunderbird is a useful mail client, that also supports filtering/moving mails into dedicated sub-directories according to keywords/addresses.

Chat

Your CERN account comes along with a Mattermost account, which you can activate by using the following link: (Mattermost chat: CMS experiment)

There are several channels our group maintains:

Be sure to ask senior students/postdocs to subscribe you to those you are interested in after a successful registration.

Since also the Skype chat is widely used at CERN, it is suggested to have a Skype account, too. Join it here.

Commit Rights

Ask PhD students for commit rights in the following repositories by telling them your GitHub username.

Make sure, that you watch all of these repositories on GitHub.
