rexec
REXEC(3) BSD Library Functions Manual REXEC(3)
NAME
rexec -- return stream to a remote command
LIBRARY
Compatibility Library (libcompat, -lcompat)
SYNOPSIS
int
rexec(char **ahost, int inport, char *user, char *passwd, char *cmd, int *fd2p);
DESCRIPTION
This interface is obsoleted by rcmd(3).
The rexec() 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. If a username and password are both specified, then these are used to authenticate to the foreign host; oth-
erwise 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(3)) will return a pointer to a structure, which contains the necessary port. The protocol for connection is described in detail
in rexecd(8).
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.

rcmd(3), rexecd(8)
HISTORY
The rexec() function appeared in 4.2BSD.
BUGS
The rexec() function sends the unencrypted password across the network.
The underlying service is considered a big security hole and therefore not enabled on many sites, see rexecd(8) for explanations.
