Using the Telnet Client
The system has an embedded Telnet client that enables you to connect to remote
systems. You can configure a Telnet daemon to listen in virtual routers other than the
default virtual router. You must be in the context of the desired virtual router to issue the
command.
telnet
•
Use to open a Telnet connection to a remote system.
•
Specify the IP address or name of the remote host.
•
You can specify a VRF context in which the request takes place.
•
Depending on how the remote system accepts Telnet requests, you can specify a port
number or port name through which the system will connect to the remote host. In the
Transmission Control Protocol (TCP), ports define the ends of logical connections that
carry communications. In most cases, you can accept the default, port number 23, the
Telnet port. For more information about port numbers and associated processes, see
www.iana.org.
•
You can force Telnet to use the IP address of an interface that you specify as its source
address.
•
Example
host1# telnet 192.168.35.13 fastEthernet 0
•
There is no no version.
•
See telnet.
telnet listen
•
Use to create a Telnet daemon to listen in a virtual router.
•
Example
host1(config)# virtual-router 3
host1:3(config)# telnet listen port 3223
•
Use the no version of the command to delete the daemon.
•
See telnet listen.
Configuring DNS
You can configure virtual routers to act as name resolvers for Domain Name Service
(DNS). DNS is a client/server mechanism that maps IP addresses to hostnames.
The name resolver is the client side of DNS and receives address-to-hostname requests
from its own clients when they want to contact hosts on other networks. By polling
name
servers, the name resolver learns name-to-address translations for the hosts its clients
want to contact.
