Syslog acounting

[Henrique Issamu Terada]

Hi list   Can I do the accounting of history commands in a router just using a Syslog Server ? Or do I need a radius or tacacs+ , like a CiscoSecure?   I'd like to use local authentication , and for each user, record the commands he had done in the router. The syslog Server is a 3CDaemon, from 3COM.   thanks   Henrique Issamu Terada CPM Comunicações - Brazil CCNA Certified
