| access_control_allow_origin | Comma separated list of IP subnets to accept/deny | -0.0.0.0/0,+192.168/16 |
| | | |
| | Ex: -0.0.0.0/0,+192.168.0.0/16 | |
| | (deny all accesses, only allow 192.168.0.0/16 subnet) | |
+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| enable_keep_alive | Allows clients to reuse TCP connection for subsequent | no |
| | HTTP requests, which improves performance. | |
+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| listening_ports | Comma-separated list of ips:ports to listen on. | 127.0.0.1:2020 |
| | If the port is SSL, a letter s must be appended. | |
| | Ex: listening_ports = 80,443s | |
+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| log_level | Loglevel (debug, info, notice, warn, err, emerg, crit) | info |
+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| num_threads | Number of worker threads. | 50 |
+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| request_timeout_ms | Timeout for network read and network write operations. | 30000 |
| | In milliseconds. | |
+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| run_as_user | Switch to given user credentials after startup. | uts-server |
| | Required to run on privileged ports as non root user. | |
+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| ssl_ca_file | Path to a .pem file containing trusted certificates. | /etc/uts-server/ca.pem |
| | The file may contain more than one certificate. | |
+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| ssl_ca_path | Name of a directory containing trusted CA certificates. | /etc/ssl/ca/ |
+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| ssl_certificate | Path to the SSL certificate file . | /etc/uts-server/cert.pem |
| | PEM format must contain private key and certificate. | |
+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| ssl_cipher_list | See https://www.openssl.org/docs/manmaster/apps/ciphers.html | ALL:!eNULL |
| | for more detailed | |
+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| ssl_default_verify_paths | Loads default trusted certificates | yes |
| | locations set at openssl compile time. | |
+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| ssl_protocol_version | Sets the minimal accepted version of SSL/TLS protocol | 3 |
| | according to the table: | |
| | | |
| | SSL2+SSL3+TLS1.0+TLS1.1+TLS1.2 -> 0 | |
| | | |
| | SSL3+TLS1.0+TLS1.1+TLS1.2 -> 1 | |
| | | |
| | TLS1.0+TLS1.1+TLS1.2 -> 2 | |
| | | |
| | TLS1.1+TLS1.2 -> 3 | |
| | | |

+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| ssl_short_trust | Enables the use of short lived certificates | no |
+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| ssl_verify_depth | Sets maximum depth of certificate chain. | 9 |
| | If client's certificate chain is longer | |
| | than the depth set here connection is refused. | |
+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| ssl_verify_peer | Enable client's certificate verification by the server. | yes |
+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| tcp_nodelay | Enable TCP_NODELAY socket option on client connections. | 0 |
+-----------------------------+---------------------------------------------------------------------+--------------------------------------+
| throttle | Limit download speed for clients. | \*=0 |
| | | |
| | Throttle is a comma-separated list of key=value pairs: | |
| | | |
| | - \* -> limit speed for all connections | |
| | | |
| | - x.x.x.x/mask -> limit speed for specified subnet | |
| | | |
| | The value is a floating-point number of bytes per second, | |
| | optionally followed by a k or m character | |
| | meaning kilobytes and megabytes respectively. | |
| | | |
| | A limit of 0 means unlimited rate. | |
| | | |
| | Ex: throttle = \*=1k,10.10.0.0/16=10m,10.20.0.0/16=0 | |
