HP-UX System Administrator's Guide: Configuration Management

Other Terminal Emulators
Telnet is only one of many terminal emulators — sometimes known as virtual terminals
— that can be used to log in to remote systems, but in the UNIX world it is a common
one.
Another that is often supported by software packages on the PC for interacting with
UNIX systems is rlogin. The rlogin daemon on HP-UX systems is rlogind. The
setup and use of rlogin between HP-UX systems and PCs is quite similar to that for
Telnet, especially on the HP-UX end. rlogin (client or server) software is not part of
Windows operating systems as originally shipped; however, commercial and shareware
versions of rlogin can be found for your Windows NT-based PCs.
IMPORTANT: The telnet and rlogin terminal emulators do not provide secure
communications. For more secure communications, you can use a secure shell (ssh)
client to access HP-UX. For details on using a secure shell, see ssh(1).
