When # executing as root (or another user), your personal environment MAY # be set up to allow the dynamic linker to find the library.

In order to change to a different user/group, you # MUST be root ( or have root privleges ) to start the server. # # We STRONGLY recommend that you run the server with as few permissions # as possible. That is, if you're not using shadow passwords, the # user and group items below should be set to 'nobody'. # # On SCO (ODT 3) use "user = nouser" and "group = nogroup". # # NOTE that some kernels refuse to setgid(group) when the value of # (unsigned)group is above 60000; don't use group nobody on these systems! # # On systems with shadow passwords, you might have to set 'group = shadow' # for the server to be able to read the shadow password file.

The reply packet may be # lost in the network, and the NAS will not see it. The NAS will then # re-send the request, and the server will respond quickly with the # cached reply. # # If this value is set too low, then duplicate requests from the NAS # MAY NOT be detected, and will instead be handled as seperate requests. # # If this value is set too high, then the server will cache too many # requests, and some new requests may get blocked.

This should be 256 multiplied by the number of clients. # e.g. With 4 clients, this number should be 1024. # # If this number is too low, then when the server becomes busy, # it will not respond to any new requests, until the 'cleanup_delay' # time has passed, and it has removed the old requests. # # If this number is set too high, then the server will use a bit more # memory for no real benefit. # # If you aren't sure what it should be set to, it's better to set it # too high than too low.

Many new servers and # NAS boxes use 1812, which can create interoperability problems. # # The port is defined here to be 0 so that the server will pick up # the machine's local configuration for the radius port, as defined # in /etc/services. # # If you want to use the default RADIUS port as defined on your server, # (usually through 'grep radius /etc/services') set this to 0 (zero). # # A port given on the command-line via '-p' over-rides this one. # port = 0 # hostname_lookups: Log the names of clients or just their IP addresses # e.g., www.freeradius.org (on) or 206.47.27.232 (off). # # The default is 'off' because it would be overall better for the net # if people had to knowingly turn this feature on, since enabling it # means that each client request will result in AT LEAST one lookup # request to the nameserver. Enabling hostname_lookups will also # mean that your server may stop randomly for 30 seconds from time # to time, if the DNS requests take too long. # # Turning hostname lookups off also means that the server won't block # for 30 seconds, if it sees an IP address which has no name associated # with it. # # allowed values: {no, yes} # hostname_lookups = no # Core dumps are a bad thing.

This may help slow down a DoS # attack. It also helps to slow down people trying to brute-force # crack a users password. # # Setting this number to 0 means "send rejects immediately" # # If this number is set higher than 'cleanup_delay', then the # rejects will be sent at 'cleanup_delay' time, when the request # is deleted from the internal cache of requests. # # Useful ranges: 1 to 5 reject_delay = 1 # # status_server: Whether or not the server will respond # to Status-Server requests. # # Normally this should be set to "no", because they're useless. # See: http://www.freeradius.org/rfc/rfc2865.html#Keep-Alives # # However, certain NAS boxes may require them. # # When sent a Status-Server message, the server responds with # and Access-Accept packet, containing a Reply-Message attribute, # which is a string describing how long the server has been # running. # status_server = no } # PROXY CONFIGURATION # # proxy_requests: Turns proxying of RADIUS requests on or off. # # The server has proxying turned on by default.

If you # don't have any spare threads, then the request handling will # be delayed while a new thread is created, and added to the pool. # # You probably don't want too many spare threads around, # otherwise they'll be sitting there taking up resources, and # not doing anything productive. # # The numbers given below should be adequate for most situations. # thread pool { # Number of servers to start initially --- should be a reasonable # ballpark figure. start_servers = 5 # Limit on the total number of servers running. # # If this limit is ever reached, clients will be LOCKED OUT, so it # should NOT BE SET TOO LOW. It is intended mainly as a brake to # keep a runaway server from taking the system with it as it spirals # down... # # You may find that the server is regularly reaching the # 'max_servers' number of threads, and that increasing # 'max_servers' doesn't seem to make much difference. # # If this is the case, then the problem is MOST LIKELY that # your back-end databases are taking too long to respond, and # are preventing the server from responding in a timely manner. # # The solution is NOT do keep increasing the 'max_servers' # value, but instead to fix the underlying cause of the # problem: slow database, or 'hostname_lookups=yes'. # # For more information, see 'max_request_time', above. # max_servers = 32 # Server-pool size regulation. Rather than making you guess # how many servers you need, FreeRADIUS dynamically adapts to # the load it sees, that is, it tries to maintain enough # servers to handle the current load, plus a few spare # servers to handle transient load spikes. # # It does this by periodically checking how many servers are # waiting for a request. If there are fewer than # min_spare_servers, it creates a new spare. If there are # more than max_spare_servers, some of the spares die off. # The default values are probably OK for most sites. # min_spare_servers = 3 max_spare_servers = 10 # There may be memory leaks or resource allocation problems with # the server. If so, set this value to 300 or so, so that the # resources will be cleaned up periodically. # # This should only be necessary if there are serious bugs in the # server which have not yet been fixed. # # '0' is a special value meaning 'infinity', or 'the servers never # exit' max_requests_per_server = 0 } # MODULE CONFIGURATION # # The names and configuration of each module is located in this section. # # After the modules are defined here, they may be referred to by name, # in other sections of this configuration file. # modules { # # Each module has a configuration as follows: # # name [ instance ] { # config_item = value # ... # } # # The 'name' is used to load the 'rlm_name' library # which implements the functionality of the module. # # The 'instance' is optional.
