Procan is a utility that prints information about process parameters to. It has been written to better understand. UNIX process properties and for debugging socat, but might be. The life cycle of a socat instance typically consists of four phases. In the init phase, the command line options are parsed and logging is.

The current Patcher 2. In the transfer phase, socat watches both streams read and write file. When one of the streams effectively reaches EOF, the closing phase. Socat transfers the EOF condition to the other stream. For a defined time socat continues to transfer data in. OPTIONSSocat provides some command line options that modify the behaviour of the.

Writes the transferred data not only to their target streams, but also to. The output format is hexadecimal, prefixed with or lt. Can be combined with. Sets the data transfer block lt size sizet. At most lt size bytes are transferred per step. Default is 8. 19. By default, socat terminates when an error occurred to prevent the process. With this. option, socat is sloppy with errors and tries to continue. Even with this. option, socat will exit on fatals, and will abort connection attempts when. When one channel has reached EOF, the write part of the other channel is shut. Then, socat waits lt timeout timeval seconds. Default is 0. 5 seconds. This timeout only applies to. When during. the timeout interval the read part gives EOF, socat terminates without. Tlt timeout. Total inactivity timeout when socat is already in the transfer loop and. Useful with protocols like UDP that cannot transfer EOF. Uses unidirectional mode. The first address is only used for reading, and the. Uses unidirectional mode in reverse direction. The first address is only. During address option parsing, dont check if the option is considered. Use it if you want to force, e. Llt lockfile. If lockfile exists, exits with error. If lockfile does not exist, creates it. Wlt lockfile. If lockfile exists, waits until it disappears. When lockfile does not exist. Use IP version 4 in case that the addresses do not implicitly or explicitly. Use IP version 6 in case that the addresses do not implicitly or explicitly. ADDRESS SPECIFICATIONS. With the address command line arguments, the user gives socat instructions and. An address specification usually consists of an address type. The keyword specifies the address type e. TCP4, OPEN, EXEC. For some. keywords there exist synonyms for STDIO, TCP for TCP4. Keywords are case. For a few special address types, the keyword may be omitted. Address specifications starting with a number are assumed to be FD raw file. GOPEN generic file open is. The required number and type of address parameters depend on the address. E. g., TCP4 requires a server specification name or address, and a port. Zero or more address options may be given with each address. They influence the. Options consist of an option keyword or an option keyword and a value. Option keywords are case insensitive. For filtering the options that are useful with an address. For. each address type there is a set of option groups allowed. Only options. belonging to one of these address groups may be used except with option g. Address specifications following the above schema are also called single. Two single addresses can be combined with to form a dual type. Here, the first address is used by socat for reading. There is no way to specify an option only once. Usually, addresses are opened in readwrite. When an address is part of a dual address specification, or when. U is used, an address might be. Considering this is important with some. With socat version 1. If one of the characters is found, the corresponding closing. Within these. constructs, socats special characters and strings, All those characters and strings can be escaped with or within. This section describes the available address types with their keywords. CREATE lt filename. Opens lt filename with. This address type requires write only context, because a file opened with. Flags like OLARGEFILE cannot be applied. If you need them use. OPEN with options. If lt filename is a named pipe. Option groups FD,REG,NAMEDUseful options. See also OPEN, GOPENEXEC lt command line. Forks a sub process that establishes communication with its parent process. If the program name. ARGV0. If the. program name is a relative. After successful program start, socat writes data to stdin of the. UNIX domain socket generated by. Option groups FD,SOCKET,EXEC,FORK,TERMIOSUseful options. See also SYSTEMFD lt fdnum.

Generic open This address type tries to handle any file system entry. If it already exists, its type is checked. In case of a UNIX domain socket, socat connects if connecting fails. If the entry is not a socket, socat opens it applying the. If it does not exist, it is opened with flag. Option groups FD,REG,SOCKET,NAMED,OPENSee also. Canon Ps 1000 Manual.
