SYNOPSIS
rexec [options] command
DESCRIPTION
rexec executes commands on a remote host using the rexec protocol (TCP port 512). It authenticates with a username and password, then runs the specified command on the remote system.Note: rexec transmits credentials and data in plain text and is insecure. Use SSH for encrypted remote command execution.
PARAMETERS
-h, --host host
Specify remote host-u, --username user
Specify remote username-P, --port port
Specify remote port-n, --noerr
Do not create a separate error stream-d, --password password
Specify password (use '-' to read from stdin)
CAVEATS
Transmits credentials and data unencrypted. Not recommended for use over untrusted networks. Consider SSH as a secure alternative.
HISTORY
Part of GNU inetutils, providing classic Unix networking utilities. Largely superseded by SSH for security reasons.
