+
+        # rcmd -ssh_port [myport] [myclient] ...

+    - 'my_ip' is the client ip address and;
+    - 'client_key' is the client supported ssl keys as try for the remote access)
+    - the RCMD-0.3.2 is required
+
+    BEWARE: This schenarios are obsoletes and may be unsecure connection.
+    The best practices is refresh the SSH client and server to supported versions.
+
+    Check the SSH options that to you need assign on the client.
+
+    i.e:
+
+       # ssh -o HostKeyAlgorithms=+[mytypes]
+           -o PubkeyAcceptedAlgorithms+[mykeys]
+           -c [mycipher_specs] [myclient1] [mycommand]
+
+    a) using options by command:
+
+        # rcmd -ssh-option HostKeyAlgorithms=+[mytypes]
+        -ssh-option PubkeyAcceptedAlgorithms+[mykeys]
+        -ssh-cipher [mycipher_specs] [myclient1,myclient2] [mycommand]
+
+       NOTE: This format will be applied for all clients in [myclient list]
+
+    b) based /etc/rcmd.d/rcmd.conf:
+
+       set SSH_OPTION HostKeyAlgorithms=+[mytypes
+       set SSH_OPTION PubkeyAcceptedAlgorithms+[mykeys]
+       set SSH_CIPHER [mycipher_specs]
+
+        # rcmd [myclient] [mycommand]
+
+       NOTE: This option will be enforced for all clients in [myclient list]
+
+    c) assigning in the client:
+
+        # rcmdmgnt -assign
+        -option ssh_options:HostKeyAlgorithms=+[mytypes]
+        -option ssh_options:PubkeyAcceptedAlgorithms+[mykeys]
+        -option ssh_cipher:[mycipher_specs] myclient1
+       and
+        # rcmd [myclient1,myclient2] [mycommand]
+
+       NOTE: The clients will be different ssh options.
+       NOTE: The special options will be for 'myclient1' only.
+       NOTE: If the 'myclient1' has been system refreshed (SSH upgrades) you must review the options.
