kparasch / backup-to-eos

Simple script that tries to transfer files of a folder to EOS.

Setup instructions

• Install Kerberos and setup for lxplus by modifying your local /etc/krb5.conf file to include the following:

[realms]
    CERN.CH = {
        default_domain = cern.ch
        kpasswd_server = cerndc.cern.ch
        admin_server = cerndc.cern.ch
        kdc = cerndc.cern.ch
    }

[domain_realm]
    cern.ch = CERN.CH
    .cern.ch = CERN.CH

• Copy into the file ~/.ssh/config the following:

Host *.cern.ch lxplus*
        User kparasch
        GSSAPITrustDns yes
        GSSAPIAuthentication yes
        GSSAPIDelegateCredentials yes
        ForwardX11 yes
        ForwardX11Trusted no

modifying the User variable as necessary.

Run kinit and aklog to enable afs access without asking password each time.
