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: With Internet Services protocols (like telnet, rlogin, rsh, and rcp)
information, including passwords, is passed between two systems in clear text and is
not encrypted. Use Internet Services only between hosts that are well-known and
defined to each other and within a private internal network behind a firewall. When
communicating over an untrusted network, secure the communications using IPSec
or Kerberos. For more information regarding secure alternatives and system security
with HP-UX, see HP-UX System Administrator's Guide:Security Management.
