some issues on License installing(1)

Accelerated Computing HPC Compilers Legacy PGI Compilers
1

Hi,I’m not sure I put my installing questions in this section is correctly.

I have two quesTIONS:

  1. After I installed PGI accelerator workstation license with root privileges, I set host name in the / etc / sysconfig / network correctly and restart ,then I add the $ PGI, $ LM_LISCENSE_FILE environment variable. As I know I need use lmgrd.rc start or lmgrd –c $LM_LISCENSE_FILE for activation ,but I got such information:
    (lmgrd) The license server manager (lmgrd) running as root:
    (lmgrd) This is a potential security problem and is not recommended.
    (lmgrd) Unknown host :gpuK20
    (lmgrd) EXITING DUE TO SIGNAL 33 Exit reason 1

I have to add my machine’s IP and hostname to /etc/hosts ,the problems were sovled then, but I want to know the reason.

The security risk is, according to IT, minor and has to do with file a system file access.

They recommend that for auto-reboot, the owner of lmgrd in init.d area not be root
to avoid the message.

$ LM_LICENSE_FILE is the generic name for the license location or port@host name.

The hostname in the license file (gpuK20?) should be mapped to the IPAddress of
gpuK20, so that

% ping gpuK20

has the same value as

% lmutil lmhostid -internet

and in the best cases, this IPaddress is tied to the Network device
(% /sbin/ifconfig) that has the MAC that is the hostid in your license.
