May 16, 2001Internet Access for Academic Networks in Lorraine16 StanNet : Exploitation and operating team StanNet network and system services are managed : by a team of 5 network engineers and 3 system engineers This team is located in the inter-university network/computing resource center The has some specific missions : provide network and system services guarantee the connectivity and the good health of the network/system network/system evolution with technological survey (development, testing)

May 16, 2001Internet Access for Academic Networks in Lorraine17 StanNet : Exploitation and operating team To provide its mission, the CIRIL Team uses several tools : device configuration (telnet, scripts, web-based administration) IP and level 2 supervision (netup, traceroute, SNMP) Security configuration (ACL + scripts) Security supervision (ACL + syslog ) traffic metrology and statistics with, a tool developed by the CIRIL
