How to connect without password to lxplus
- The CERN wiki page is here
- On ubuntu, you need to:
- install kerberos
sudo apt-get install krb5-user with domain: CERN.CH
- Copy to /etc/krb5.conf the config file taken from CERN here.
- Do a kinit . It should ask you for you CERN password, specifying yourlogin@CERN.CH. If this is wrong, specify it yourself with kinit yourlogin@CERN.CH
- This should give you a valid kerberos ticket lasting 25h, meaning you will be able to connect passwordlessly to lxplus as long as the kerberos ticket is valid.
- To check if this worked, do a klist -f. Check the Flags, there should be an F, meaning you will have access to your /afs space.
- Connect to lxplus using the following ssh options (replace MYLOGIN with the CERN login):
ssh -2 -oGSSAPIAuthentication=yes -oGSSAPIDelegateCredentials=yes -oGSSAPITrustDNS=yes -l MYLOGIN lxplus.cern.ch
How to copy data from disk (eg. beo5) to you space at lxplus?
