IXPC(1) General Commands Manual IXPC(1) NAME
ixpc - ixp client SYNOPSIS
ixpc [-a address] action file ixpc -v DESCRIPTION
Overview ixpc is a client to access a 9P file server from the command line or from shell scripts. It can be used to configure wmii(1). Options -a address Lets you specify the address to which ixpc will establish a connection. If this option is not supplied, and the environment variable IXP_ADDRESS is set, ixpc will use this value as its address. Currently, the address can only be a unix socket file or a tcp socket. The syntax for address is taken (along with many other profound ideas) from the Plan 9 operating system and has the form unix!/path/to/socket for unix socket files, and tcp!hostname!port for tcp sockets. -v Prints version information to stdout, then exits. The syntax of the actions is as follows: write Writes the supplied data from the standard input to file, overwriting any previous data. The data to be written is arbitrary and only gains meaning (and restrictions) when it is interpreted by wmiiwm(1). See EXAMPLES below. xwrite The same as write, but the data is taken from subsequent arguments, rather than the standard input. create Creates file or directory. If the file exists, nothing is done. ls Lists files and directories. read Reads file or directory contents. remove Removes file or directory tree. ENVIRONMENT
IXP_ADDRESS See above. EXAMPLES
ixpc ls / This prints the root directory of the wmii filesystem, if IXP_ADDRESS is set to the address of wmii. For more information about the contents of this filesystem, see wmiiwm(1). ixpc xwrite /ctl quit Write 'quit' to the main control file of the wmii filesystem, effectively leaving wmii. ixpc write /keys < keys.txt Replace the contents of /keys with the contents of keys.txt SEE ALSO

SOCKET(1) General Commands Manual SOCKET(1) NAME
socket - create a TCP or a UNIX domain socket and connect to stdin/out SYNOPSIS
socket [ -bcfqrvw ] [ -p command ] [ -B local address ] host port socket [ -bcfqrvw ] [ -p command ] /path socket [ -bcfqrvw ] [ -p command ] [ -B local address ] -s [ -l ] port socket [ -bcfqrvw ] [ -p command ] -s [ -l ] /path DESCRIPTION
Socket creates an Internet domain TCP or a UNIX domain stream socket and connects it to stdin and stdout. The host argument can be an Internet number in dot-notation (like ``130.149.28.10'') or a domain name. In this case it must be possible to resolve the name to a valid Internet address with gethostbyname(3). The port argument can be a port number or a service name which can be mapped to a port number by getservbyname(3). If an UNIX domain socket is wanted to be created instead of an Internet socket, specify the path instead of an internet (canonical domain named or dot-notated) host. The hostname is treated as a pathname if contains at least a single slash. I.e. if one wants to create or connect to a socket in the current directory, use ./filename to specify the connection point. OPTIONS
-b (background) The program forks itself into the background, detaches from its controlling tty, closes the file descriptors associated with the tty, and changes its current directory to the root directory. -B (local address) This option specifies which local address to binded to when making a connection. -c (crlf) Linefeed characters (LF) are converted to a Carriage Return Linefeed sequence (CRLF) when written to the socket. CRLF sequences read from the socket are converted to a single LF. -f (fork) When a server connection has been accepted, a separate process is forked to handle the connection in background. -l (loop) (only valid with -s) After a connection has been closed, another connection is accepted. -p (program) The specified command is executed for each connection. Its standard input, standard output, and standard error channels are con- nected to the socket. Command can be any shell command since it is passed to /bin/sh. -q (quit) The connection is closed when an end-of-file condition occurs on standard input. -r (read only) No data is read from standard input and written to the socket. -s (server) A server socket is created. A hostname argument is not required of Internet sockets, only the port number but a pathname is required for UNIX domain sockets. -v (verbose) Messages about connections etc. are issued to stderr. -w (write only) No data is read from the socket and written to the standard output. -version Socket prints its version ID and terminates. This must be the first argument to have an effect. EXAMPLES
The command socket -v coma.cs.tu-berlin.de nntp connects to the nntp port (port 119) of coma.cs.tu-berlin.de (130.149.28.10). The command socket -sl 3425 creates a server socket on port 3425 on the local host and waits for a connection. After a connection has been closed, a new connection is accepted. The command socket -wslqvp "echo Socket! " 1938 creates a server socket on port 1938 on the local host and waits for a connection. When a connection is accepted, the string "Socket!" is written to the socket. No data is read from the socket and written to the finger program. The connection is closed when an end-of-file condition at the standard output of the program occurs. Then a new connection is accepted. DIAGNOSTICS
Lots of diagnostics for failed system calls. unknown host host host's address could not be resolved. Signal signal caught, exiting Socket exits on any signal other than SIGTSTP, SIGCONT, SIGCLD, SIGQUIT. A non-zero exit code is returned if socket terminates due to an error condition or a signal. SEE ALSO
ip(7), tcp(7), unix(7), accept(2), bind(2), listen(2), connect(2), socket(2), gethostbyname(3), getservbyname(3) BUGS
socket -p terminates due to a SIGPIPE signal when there is more data from the socket available than the executed program wants to read. Please report any other bugs to the author. VERSION
