If you are getting ssh errors
trying to log into modelo, then I need to remind you about the fact that we
have a new computer called modelo. It is a Linux box replacing the old Sun.
The error will look something like
this. This is
perfectly ok and you will need to remove any lines in your ~/.ssh/known_hosts
that contain the word modelo. |

The new observers computer, 'modelo', has been purchased,
configured to the first order and will be installed on Kitt Peak on Thursday
the 15th. Here are some of its specs:
- Dual 2.66 GHz Xeon Processors.
- 1 GByte of memory.
- 360 GBytes of external disk space.
- Twin 19" flat panel LCD video displays.
- DVD-RW, CD-R, CDROM drive.
- Best of all, it's running Linux!!!
Observer software:
- Aips -- After running the DDT and Y2K tests, produces AipsMarks in the
range of 118 - 125. I'm told that's extremely good. There are 5 aips disks
worth 36 Gbytes each.
- Class -- being installed as I write this. There are (5) 36 Gbyte disks
for reduced class data.
- Unipops -- In the process of being converted to Linux and will be
installed when it's ready. In the meanwhile observers will need to login
to locura and run unipops there, with their DISPLAY set back to
'modelo:0.0'.
