| - For each instrument there is an instrument computer. This computer is named like the instrument. For example, for the instrument AMOR the instrument computer is amor.psi.ch. Instrument computers are HP workstations equipped with two disks set up in RAID 1 (mirroring) configuration. For most instruments the instrument computer is located in the instruments cabin. |

| + This scheme allows us to accommodate external SINQ users without going through the pains of allocating AFS accounts for each user group. So far, security posed no problem. The local accounts on the instrument computer are not easily accessible from outside of PSI. To access those local instrument accounts the following steps are required: |
| + # Logon to balrog.psi.ch with your AFS username |
| + # Logon to any other linux machine, for example, lnsl15.psi.ch, with your AFS username |
| + # From there logon to the local accounts on the instrument computer |

| + This is so complicated because each instrument has its own instrument network segment. |
