I had 3.0.19 before and now have installed 3.0.21. But for both versions I got and get: Loading library using linker search path(s) Defaults : /lib:/usr/lib Failed with error: proto_auth.so: cannot open shared object file: No such file or directory listen { type = "auth" ipaddr = 192.168.0.254 port = 1812 limit { max_connections = 16 lifetime = 0 idle_timeout = 30 } } Loading proto_acct with path: /usr/lib/freeradius/proto_acct.so Loading proto_acct failed: /usr/lib/freeradius/proto_acct.so: cannot open shared object file: No such file or directory - No such file or directory Loading library using linker search path(s) Defaults : /lib:/usr/lib Failed with error: proto_acct.so: cannot open shared object file: No such file or directory listen { type = "acct" ipaddr = 192.168.0.254 port = 0 limit { max_connections = 16 lifetime = 0 idle_timeout = 30 } } As I saw at freeradius site there are only 2 proto_ modules - proto_vmps and proto_dhcp. Is it normal and does not it affect anythingor not ? Should I change my setting to avoid it or what is necessary to do ? Or it does not affect to anything and should be forgotten.
