REXEC(3) Library Functions Manual REXEC(3)
NAME
rexec - return stream to a remote command
SYNOPSIS
rem = rexec(ahost, inport, user, passwd, cmd, fd2p);
char **ahost;
int inport;
char *user, *passwd, *cmd;
int *fd2p;
DESCRIPTION
Rexec looks up the host *ahost using gethostbyname(3N), returning -1 if the host does not exist. Otherwise *ahost is set to the standard
name of the host. If a username and password are both specified, then these are used to authenticate to the foreign host; otherwise the
environment and then the user's .netrc file in his home directory are searched for appropriate information. If all this fails, the user is
prompted for the information.
The port inport specifies which well-known DARPA Internet port to use for the connection; the call ``getservbyname("exec", "tcp")'' (see
getservent(3N)) will return a pointer to a structure, which contains the necessary port. The protocol for connection is described in
detail in rexecd(8C).
If the connection succeeds, a socket in the Internet domain of type SOCK_STREAM is returned to the caller, and given to the remote command
as stdin and stdout. If fd2p is non-zero, then an auxiliary channel to a control process will be setup, and a descriptor for it will be
placed in *fd2p. The control process will return diagnostic output from the command (unit 2) on this channel, and will also accept bytes
on this channel as being UNIX signal numbers, to be forwarded to the process group of the command. The diagnostic information returned
does not include remote authorization failure, as the secondary connection is set up after authorization has been verified. If fd2p is 0,
then the stderr (unit 2 of the remote command) will be made the same as the stdout and no provision is made for sending arbitrary signals
to the remote process, although you may be able to get its attention by using out-of-band data.
