Using the Telnet/iX Client

Connecting and Logging On to a Remote Host

Connecting and Logging On to a Remote

Host

From the Telnet/iX Client, you must establish a connection to the

remote host you wish to access.

From the telnet> prompt, enter the OPEN command followed by the

remotehostname which is the ARPA domain name or NS node name if

the Internet Protocol (IP) address, (see “Node Names” below), and port

(if no port is speciﬁed, the program attempts to contact a Telnet server

at the standard Telnet port (23)) designated for the Telnet/iX

connection supplied by your network administrator:

telnet> OPEN [remotehostname] [port]

NOTE

Only one connection can be open at any given time. In order to open a

second connection, the ﬁrst must be closed.

IP addresses are assigned by your network administrator to uniquely

identify computer systems to allow communication between systems on

the network.

IP addresses, also called internet addresses, are in the form:

nnn.nnn.nnn.nnn

Where nnn is a number from 000 to 255, inclusive. For example, if the IP

address of the remote system is 192.1.20.125 , you would enter:

telnet> OPEN 192.1.20.125

Node Names

Besides using IP addresses with the Telnet/iX Client OPEN command,

you can use either an ARPA domain name or an NS node name in the

OPEN command. NS names are recognized if the remote and local hosts

support the Probe protocol or if the remote host name is conﬁgured in

your local node network directory. ARPA domain names are conﬁgured

in the ASCII ﬁle HOSTS.NET.SYS; or an address which points to a

system running Domain Names Services (DNS) is conﬁgured in the

ASCII ﬁle RESLVCNF.NET.SYS. For ARPA domain name conﬁguration

information, refer to the HP 3000/iX Network Planning and

Conﬁguration Guide. Obtain the node names from your network

administrator. For example, if the name, node2, is conﬁgured as a

remote host name on your network, you can enter:

telnet> OPEN node2
