Proxy Service

The Proxy Service is a gRPC & Go based proxy configuration service. The proxy settings of the Edge Devices are configured through this service.

This service configures a Redsocks transparent proxy on the device, enabling communication with HTTP proxy servers using the http-connect mode. Only connections via HTTP proxies are supported.

NOTICE

The repository for this package is not available on the Siemens Industrial Edge public GitHub. Source code access can be granted to device builder partners upon request, subject to review of their implementation plans.

ProxyConfig

Interface type holds settings for a proxy server.

Field	Type	Label	Description
proxyAddress	[string](#string)		Hostname/IP and port (separated by colon) of the proxy server
auth	[Authentication](#string)		Authentication details for accessing the proxy
noProxyAddresses	[string](#string)	repeated	List of addresses or domains to bypass the proxy
httpCustomPorts	[int32](#int32)	repeated	Custom HTTP ports for the proxy server (optional)
httpsCustomPorts	[int32](#int32)	repeated	Custom HTTPS ports for the proxy server (optional)

Authentication

Type that contains authentication details for the proxy server.

Field	Type	Label	Description
userName	[string](#string)
password	[string](#string)

ProxyConfigService

ProxyConfigService uses a UNIX Domain Socket "/var/run/devicemodel/sysproxy.sock" for GRPC communication. protoc generates both client and server instance for this Service. GRPC Status codes : https://developers.google.com/maps-booking/reference/grpc-api/status_codes .

double		double	double	float	float64	double	float	Float
float		float	float	float	float32	float	float	Float
int32	Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint32 instead.	int32	int	int	int32	int	integer	Bignum or Fixnum (as required)
int64	Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint64 instead.	int64	long	int/long	int64	long	integer/string	Bignum
uint32	Uses variable-length encoding.	uint32	int	int/long	uint32	uint	integer	Bignum or Fixnum (as required)
uint64	Uses variable-length encoding.	uint64	long	int/long	uint64	ulong	integer/string	Bignum or Fixnum (as required)
sint32	Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s.	int32	int	int	int32	int	integer	Bignum or Fixnum (as required)
sint64	Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int64s.	int64	long	int/long	int64	long	integer/string	Bignum
fixed32	Always four bytes. More efficient than uint32 if values are often greater than 2^28.	uint32	int	int	uint32	uint	integer	Bignum or Fixnum (as required)

bool		bool	boolean	boolean	bool	bool	boolean	TrueClass/FalseClass
string	A string must always contain UTF-8 encoded or 7-bit ASCII text.	string	String	str/unicode	string	string	string	String (UTF-8)
