Hi, We're running freeradius server v2.0.3 and restart of the daemon failed with: #/etc/init.d/radiusd restart Stopping RADIUS server: [FAILED] Starting RADIUS server: Fri Jul 16 07:50:16 2010 : Info: Starting - reading configuration files ... [FAILED] In the radius.log, it shows: Error: There appears to be another RADIUS server running on the authentication port 1812 <--- The odd thing is that there is no radiusd process running on the Linux server at all: # ps aux | grep rad root 4869 0.0 0.0 4544 636 pts/1 S+ 12:11 0:00 grep rad #Debug messages: /usr/sbin/radiusd -X restart Starting - reading configuration files ... reread_config: reading radiusd.conf Config: including file: /etc/raddb/proxy.conf Config: including file: /etc/raddb/clients.conf Config: including file: /etc/raddb/snmp.conf Config: including file: /etc/raddb/sql.conf main: prefix = "/" main: localstatedir = "//var" main: logdir = "/var/log" main: libdir = "//lib" main: radacctdir = "/etc/radacct" main: hostname_lookups = no main: max_request_time = 30 main: cleanup_delay = 5 main: max_requests = 1024 main: delete_blocked_requests = 0 main: port = 1812 main: allow_core_dumps = no main: log_stripped_names = yes main: log_file = "/var/log/radius.log" main: log_auth = yes main: log_auth_badpass = no main: log_auth_goodpass = no main: pidfile = "//var/run/radiusd/radiusd.pid" main: bind_address = 10.25.210.21 IP address [10.25.210.21] main: user = "(null)" main: group = "(null)" main: usercollide = no main: lower_user = "no" main: lower_pass = "no" main: nospace_user = "no" main: nospace_pass = "no" main: checkrad = "//sbin/checkrad" main: proxy_requests = no proxy: retry_delay = 5 proxy: retry_count = 3 proxy: synchronous = no proxy: default_fallback = yes proxy: dead_time = 120 proxy: post_proxy_authorize = yes proxy: wake_all_if_all_dead = no security: max_attributes = 200 security: reject_delay = 1 security: status_server = no main: debug_level = 0 read_config_files: reading dictionary read_config_files: reading naslist Using deprecated naslist file.

Thanks.
