The Diagnosis of Connection Errors

There are many situations that cause troubles to users that try to connect CSC and the corpus.csc.fi machine. The following set of questions is an attempt to make error diagnosis in these situations easier.

Step 1. Do you have a valid Unix account (username) at CSC
  1. Have you applied for the right to use the Language Bank of Finland?
  2. Have you received username and a password from CSC?
  3. Have you used your account recently? After two years from the creation of accounts, unused accounts are closed regularly (once a year) by CSC if the user has not requested for extension.
    If your userid has been removed from our machines, it means that you must apply again a new permission to use the resources of the Language Bank. The procedure is the same as it was for the last time.
  4. Have you changed your password as required? Do you remember the password? If necessary, you may ask the USERMGR at CSC to regenerate an initial password for your account.

Step 2. Can you use CSC Scientist's User Interface?
  1. Can you log in to the CSC Scientist's User Interface at http://www.csc.fi/suomi/tutkija/index.phtml.en Please check your account information at https://hotpage.csc.fi/cgi-bin/db/tietoni Problems at this point may suggest that your Unix home directory is not correctly set in the /etc/passwd file. Some years ago, CSC changed the locations of the sub directories of /home and this change may have not been spread to the settings of some users. If this could be the problem, please contact the LING and USERMGR at CSC asking for the remaining settings update.
  2. Can you use the corpus tool Lemmie in the CSC Scientist's User Interface? In one typical error situation the user gets one of the following error messages:
    • when using Lemmie1 at location https://hotpage.csc.fi/su-cgi-bin/appl/ling/lemmie/lemmie.cgi?page=search:
      Error
      Cannot find settings file: /v/net/hotpage.csc.fi/serverroot/cgi-lib/appl/ling/lemmie/.lemmie_web.rc
      Please report the error to the Lemmie Administrator ling.csc.fi
      No such file or directory.
      
    • when using Lemmie2 at location https://hotpage.csc.fi/su-cgi-bin/appl/ling/lemmie2/search.cgi:
      Fatal error
      Cannot find default settings.
      Please report this error and whatever you did that might have caused it to ling.csc.fi.
      Sorry for the inconvenience.
      The Language Bank Administrator
      
      The problem in this case was that a version of Lemmie1 and Lemmie2 did not write initialization files to the user's home directory. This problem case is not likely to reoccur. Software upgrades to Lemmie may change its behaviour but resulting errors do not usually suggest that there is a problem with the connection.

  1. In the case of mystical faults, you may ask the USERMGR at CSC to check your account. There has been some infrequent problems with location or existence of user's home directory or with the Unix groups attributed to the user.

Step 3. Have you problems with SSH Connection only?
  1. Have somebody else managed to connect him- or herself to corpus.csc.fi from your machine? If yes, your password may be different in different services of CSC. This may be caused by an error by the mechanism that makes the passwords the same in all machines after your has been changed, or because somebody (you) have changed your password and it has not been copied to all machines yet (it takes usually an hour). Cure: if the superuser now changes your password, it should be updated to all machines correctly.
  2. Have you tried to connect corpus.csc.fi from venus.ling.helsinki.fi (the users of the UHLCS) or from some other machine of the Finnish universities? Have you succeeded? The problem is related to your machine, but probably not to the allowed hosts at CSC since you can connect corpus from everywhere.

HelpdeskProblemAbstract I have followed your instructions but I am still not able to connect corpus.csc.fi. The host rejects my attempts or something else is wrong.
