STATISTICS SERVER

The link to this page is http://www.gse.uci.edu/research/research_statistics.php.

The Statistics Server System consists of 5, AMD Opteron 248 machines. Each machine has two, 2.4GHz processors and between 4-8GB of main memory. The boxes have IP addresses in the range of 128.200.163.101-105.

The 128.200.163.101 box is the main file server for the system. It has 4, 1TB disk drives, sda1, sdb1, sdc1 and sdd1. The CentOS (Free RedHat Enterprise Linux) operating system is installed on the sda1 drive. All user accounts are in the /home directory.

Linux system software updates are done nightly between 3-4am. The sdd1 drive is used for backups which are done every night between 5-7am. Currently the backups span about 12 days before the oldest backup is overwritten. If you think you may have lost a fileon tehmachine, please contact DoE Tech Services in less than 12 days (sooner is better) to retireve a backup copy.

The /mnt/sdb1 system holds all the Adolescent Health research data. Only AddHealth users are allowed access to the AddHealth information. By AddHealth requirements all AddHealth research must be kept in the /mnt/sdb1/AddHealth directory. Also by AddHelath requirements, the information is never backed up. AddHealth data files may not be copied or removed from the machine for any reason. AddHealth analyses results may be copied from machine using sftp programs.

Currently Stata, StatTransfer, SAS, R, gcc and emacs are installed on the 128.200.163.101 machine. Fortran 95/2003, HLM, MatLab and Mathematica are all scheduled for installation in the near future. The goal is to keep all software versions current. At this time all versions of software are command-line only. We have been asked about MPlus, but MPlus only runs on Windows machines. 

When an account is made for you as a new user on the system, you should receive an email similar to the following:


YourFirstname YourLastname

At the request of Firstname Lastname, an account for you has been made on the Department of Education Statistics Server. Following is your personal account access information on the DoE Statistics Server:

Login: YourUCInetID
Password: ***********

You will need to use ssh/sftp software to connect to the Statistics Server. If you are trying to connect from off-campus or via wireless, you must run the campus VPN software. See http://oit.uci.edu/security/vpn to get a free copy of the UCI campus VPN software if you need it.

On Apple OS-X machines, ssh already exists in the Terminal window application. On OS-X you can get a free copy of Fetch from the http://nacs.uci.edu Software Database to implement sftp. Under Windows, Dept of Ed Technical Services recommends using the Tunnelier program from Bitvise for both ssh and sftp. See http://www.bitvise.com/tunnelier.  Download and install on your local machine. Some users prefer the Putty ssh/sftp tools ( http://www.putty.org ). There are other ssh/sftp tools which also work well.

The Statistics Server has an IP Address of 128.200.163.101. Upon your first successful ssh connection to the 128.200.163.101 machine, you should type “passwd” (without quotes) and change your initial password to one of your own choosing. You will have to provide your initial password above followed by your new password entered twice. There are password constraints in place on the machine. If you need guidelines on choosing a good password, see http://www.nacs.uci.edu/ucinetid/password.html.

The passwd program will inform you if the password you wish to use in not acceptable. Keep trying until you successfully change your password. Password aging is in place on the machine for security purposes. You must login every 30 days or less or your account will be suspended. You must change your password once every 90 days or less or your account will be suspended. After account suspension contact DoE Technical Services (see http://www.gse.uci.edu/tech) to have your account reinstated.

If you have any difficulties connecting to the Statistics Server and changing your password, please contact the UCI Department of Education Technical Services. See http://www.gse.uci.edu/tech.

Unix Tutorial Information

I have been asked to add links to Linux Tutorials information. Your best bet may be to search online for something like "linux user tutorial," "linux user guide," "unix command line" or "unix shell command" and check a few results to see what is agreeable to you. Of the links I found, I thought these were reasonable:

http://linux.org.mt/article/terminal

http://www.linux-tutorial.info/modules.php?name=MContent&pageid=49

ftp://metalab.unc.edu/pub/Linux/docs/linux-doc-project/users-guide/user-beta-1.pdf.zip (3.3.1-2, and chapter 4)

For those of you experienced with DOS, the following may be helpful:

http://control-escape.com/linux/lx-translate.html

The basic commands you need to know to get by are passwd, ls, more, cd, cp, mv, rm, mkdir, rmdir, chmod and chgrp. You may also wish to learn vi or nano as *nix text editors. Many people prefer to edit their Stata do files on their local machines (using notepad, wordpad, textedit, etc.) and then upload the files. The command to invoke Stata is stata-se.

Finally, the following link offered an exhaustively comprehensive list of resources for Linux:
