i have to check n configure..

1. the following attributes set are allowed to have a non-expiring password:

/etc/ftpusers or
/etc/vsftpd.ftpusers

Id must exist in file

Restrict ftp access

*how to check for specifc servcie status on esxi like if ftp is installed or not ?


2.User stanzas with all of the following attributes set are allowed to have a non-expiring password:

File /etc/security/$FILENAME must be placed in the /etc/security directory and be identical to the filename used in the preceding rule.

Note:File containing a list of userids, one per line, that are not allowed to perform an interactive login to the system            
The actual filename may vary.

3. File /etc/pam.d/system-auth:

auth required /lib/security/$ISA/pam_listfile.so item=user sense=deny file=/etc/security/$FILENAMEonerr=succeed

Note: This entry must precede any entries of type auth whose control field is set to the value sufficient.

Note: The actual filename may vary, but it must be placed in the /etc/security directory and have permissions set to 0640 or more restrictive.

pls advcie to implement above  in esxi 4.1
