Hi Everyone, I am testing Freeradius v3.2.3 with cache module. the driver "rlm_cache_memcached". We plan to build a freeradius cluster with distributed memcached to cache user login status. During the test, I notice if memcached is offline, freeradius will either reject all new auth request or failed to start. The libmemcached document website is offline (http://docs.libmemcached.org) and I tried to search related information on google, but no luck. Does anyone know how to make rlm_cache_memcached to handle failed memcached server? the cache module config is cache { driver = "rlm_cache_memcached" memcached { # Memcached configuration options, as documented here: # http://docs.libmemcached.org/libmemcached_configuration.htmlmemcached options = "--SERVER=10.4.4.5 --SERVER=10.4.4.6 --SERVER=10.4.4.7" pool { start = ${thread[pool].start_servers} min = ${thread[pool].min_spare_servers} max = ${thread[pool].max_servers} spare = ${thread[pool].max_spare_servers} uses = 0 lifetime = 0 idle_timeout = 60 } } key = "%{sha256:%{User-Name}}/%{sha256:%{User-Password}}" ttl = 150 update { # <list>:<attribute> <op> <value> # Cache all instances of Reply-Message in the reply list &reply:Reply-Message += &reply:Reply-Message[*] # Add our own to show when the cache was last updated &reply:Reply-Message += "Cache last updated at %t" } } also, the option --REMOVE_FAILED_SERVERS is not supported Regards, Eric
