hi, all: I want to see the authentication requests in the log file, so I set radiusd.conf as below: log_auth = yes prefix = /usr/local exec_prefix = ${prefix} sysconfdir = ${prefix}/etc localstatedir = ${prefix}/var sbindir = ${exec_prefix}/sbin logdir = ${localstatedir}/log/radius raddbdir = ${sysconfdir}/raddb radacctdir = ${logdir}/radacct log_file = ${logdir}/radius.log But in radius.log, I can only see something as below: Fri Apr 17 16:06:15 2009 : Info: Using deprecated naslist file. Support for this will go away soon. Fri Apr 17 16:06:15 2009 : Info: rlm_exec: Wait=yes but no output defined. Did you mean output=none? Fri Apr 17 16:06:15 2009 : Info: Ready to process requests. So,how can I see the authentication requests comes from client? best regard yiyongyun
