LSB_PRE_POST_EXEC_USER
Syntax
LSB_PRE_POST_EXEC_USER
=user_name
Description
UNIX only.
Specifies the authorized user for running queue level pre-execution and post-execution
commands. When this parameter is defined, the queue level pre-execution and post-
execution commands will be run as the specified user.
In particular, you can define this parameter if you need to run commands as root on
UNIX.
If you configure this parameter as root, the
LD_PRELOAD and LD_LIBRARY_PATH
variables are removed from the pre-execution, post-execution, and eexec environments
for security purposes.
Pre-execution and post-execution commands are configured at the queue level by the
LSF administrator.
You can only define a single user name in this parameter.
Default
Undefined. Pre-execution and post-execution commands are run as the user who
submitted the job.
LSF_EAUTH_KEY
Syntax
LSF_EAUTH_KEY
=key
Description
UNIX and Windows.
Specifies a key
eauth uses to encrypt and decrypt user authentication data.
This parameter provides a way to increase security at a site. The rule to choosing a key
is the same as for choosing a password.
If you want to improve the security of your site by specifying a key, make sure it is at least
six characters long and uses only printable characters (as when choosing a normal UNIX
password).
If you want to change the key, modify the
lsf.sudoers file on every host. For the
hosts to work together, they must all use the same key.
Default
Undefined. eauth encrypts and decrypts authentication data using an internal key.
LSF_EAUTH_USER
Syntax
LSF_EAUTH_USER
=user_name
