Lmx.netrun process, Process lmx.extd | Siemens V4.0 manual

Advanced Server for UNIX architecture

Process model

The lmx.netrun process

This process provides the Netrun service: UNIX programs can be executed on the server from MS-DOS or OS/2 workstations using this process.

The process lmx.extd

The lmx.extd program is installed and configured with the installation of the software package asxsnmp. This process sets up the connection between the SNMP service and Advanced Server for UNIX; it informs the SNMP agent when Advanced Server for UNIX starts and stops.

The lmx.nvalert process

This process is not supported by Siemens Advanced Server for UNIX.
