Add new user (LDAP)

• Managing Fedora-DS

To get a untaken UID for the new accont, use nextUID.py placed in '/opt/scripts'. Note that the UID may be already in use on grape.

To add a group of new users with similar uid, use script ldapBatchAddUser.py placed in '/opt/scripts/'. You will have to run it as root, and keep in mind the following things.

       This program helps to create multiple user accounts on the fly. 
       In order to use it, you have to provide some basic information 
       of the new accounts. The new accounts will be named as "BASE$N",
       in which "BASE" is the base name, and $N is the count. You have
       to specify the starting number of $N. Users' home directory
       will be /home/BASE/BASE$N, and bear in mind that this program
       does not create /home/BASE automatically. The program will invoke
       "nextUID.py" to set UIDs for the new accounts, However, you still 
       have to take care of the GID issue yourself. All new accounts
       will use "BASE" as their passwords.

       Modify the program yourself to make it better suit your need.

       Use CTRL+C to interrupt the program when typing something wrong.

Add new user (grape)

Create account in /etc/passwd

useradd -u NEWUID -g md NAME

Update NIS (for cluster authentication)

cd /var/yp/

Gromos Live (ubuntu based live CD)

The CD is based on the one from IGC ETH with some minor modifications including:

• changing gnome background
• removing unnecessary language and game packages
• changing firefox homepage (/usr/share/ubuntu-artwork/home/index.html)
• changing license file in GROMOS directory (/opt/gromos/)
• installing gromacs to /opt
• removing nfs-common and portmap packages

Guidelines on how to modify an ubuntu live cd can be found in the following urls. Note that ALL of the above modifications are made in squash file: http://www.debuntu.org/how-to-customize-your-ubuntu-live-cd http://www.atworkonline.it/~bibe/ubuntu/custom-livecd.htm

To port the live CD to USB key drive, please refer to the following url. As Gromos Live is based on Ubuntu 7.10, we cannot use scripts written for other versions. http://www.pendrivelinux.com/2007/09/28/usb-ubuntu-710-gutsy-gibbon-install/

How to compile GROMOS96 on APAC (ac)

In order to run parallel version of GROMOS96 on APAC (ac) the following changes should be made:

In ../src/prom_db.F change the line

    call system (
   $'cat /proc/cpuinfo |grep MHz| awk {print $4} > tmp.info.xyz')

to

    call system (
   $"cat /proc/cpuinfo |grep MHz| awk '{print $4}'> tmp.info.xyz")

Single quotes became a double quote and the pair of single quotes before and after the {} became just one single quote each.

You should make the same corrections a couple of lines later as well even though the code will not enter that conditional.

Then a bit further on change it to read

   call system (
   $"cat /proc/cpuinfo |grep model |
   $  awk -F: '{print $2}' > tmp.info.xyz")

We should thank Dr Margaret Kahn from APAC for this solution.
