Network Management System on Network Equipment

Normally, network equipments require network management system for controlling and monitoring purposes. SNMP is one of the common tools used in commercial equipments for such purpose. For uClinux, a SNMP agent resided in the network device is available, known as net-snmp. Putting the net-snmp in uClinux is easy, but to extend the SNMP agent, a lot of works need to be done. First, have to clearly understand your system, what to monitor and what to configure. Then, come out with MIB. Then, write the code and integrate to the agent. That’s the work need to be done! Web controlling is a must for almost all network equipments nowadays. We start our normal ADSL modem in house with a web configuration page. So, putting the web server is necessary and uClinux supports HTTP server with single process and single thread. No fork is allowed since no-MMU in most of the embedded system. Then, we need Boa or thttpd. Both of them work pretty well. But need more knowledge on how to integrate the CGI. More works to be done.
