rcmdsh
RCMDSH(3) BSD Library Functions Manual RCMDSH(3)
NAME
rcmdsh -- return a stream to a remote command without superuser
SYNOPSIS
#include <unistd.h>
int
rcmdsh(char **ahost, int inport, const char *locuser, const char *remuser, const char *cmd, const char *rshprog);
DESCRIPTION
The rcmdsh() function is used by normal users to execute a command on a remote machine using an authentication scheme based on reserved port
numbers using rshd(8) or the value of rshprog (if non-NULL).
The rcmdsh() function looks up the host *ahost using gethostbyname(3), returning -1 if the host does not exist. Otherwise *ahost is set to
the standard name of the host and a connection is established to a server residing at the well-known Internet port ``shell/tcp'' (or whatever
port is used by rshprog). The inport argument is ignored; it is only included to provide an interface similar to rcmd(3).
If the connection succeeds, a socket in the UNIX domain of type SOCK_STREAM is returned to the caller, and given to the remote command as
stdin, stdout, and stderr.
RETURN VALUES
The rcmdsh() function returns a valid socket descriptor on success. Otherwise, -1 is returned and a diagnostic message is printed on the
standard error.
SEE ALSO
rsh(1), socketpair(2), rcmd(3), rshd(8)
HISTORY
The rcmdsh() function first appeared in OpenBSD 2.0, and made its way into FreeBSD 4.6.
BUGS
If rsh(1) encounters an error, a file descriptor is still returned instead of -1.
