rlogind provides remote command shell facilities with authentication based on privileged port numbers from trusted hosts. Like any other 7/2008R2/8/2012/10/2016 service, you can use the service utility to start and stop rlogind.
rlogind listens for service requests at port 513. When a service request is received, the following protocol is initiated:
The service checks the client's source port. If the port is not in the range 512-1023, the service aborts the connection.
The server checks the client's source address. If an entry for the client exists in both /etc/hosts and /etc/hosts.equiv, a user logging in from the client is not prompted for a password. If the address is associated with a host for which no corresponding entry exists in /etc/hosts, the user is prompted for a password, regardless of whether or not an entry for the client is present in /etc/hosts.equiv.
rlogind loads the user's profile and runs the command shell specified in the MKS Toolkit control panel applet.
installs and starts the rlogind service. To start the service without installing it, use the service command:
service start rlogind
stops and removes the rlogind service. To stop the service without removing it, use the service command:
service stop rlogind
runs rlogind as a normal program in the current console for debugging purposes.
To use this option, you require the following privileges:
Replace a process level token (SeAssignPrimaryTokenPrivilege) Increase quotas (SeIncreaseQuotaPrivilege) Act as part of the operating system (SeTcbPrivilege)
If you are lacking any of these privileges, rlogind reports which are missing. You can use priv to add these privileges and then log out and back in. For example, the following assigns all three privileges required for using this option:
priv -a SeAssignPrimaryTokenPrivilege priv -a SeIncreaseQuotaPrivilege priv -a SeTcbPrivilege

is the per-user trusted host-user pairs list.
Possible exit status values are:
There is a very brief period of time when rlogind is establishing a connection with a client that it is unavailable to establish a new connection with another client. Up to a limited number of connection attempts from other clients are buffered until rlogind is free to service one of them. Additional connection attempts beyond that limit fail. An error results from the client indicating that it was unable to find the rlogind service. In real world usage, this limitation is unlikely to be encountered. This limit is operating system dependent.
If your MKS Toolkit license only includes a single-connection license for the connectivity tools, rlogind only allows one connection at a time.
