Cisco Cisco Configuration Engine 3.5.3 Guía Para Resolver Problemas

The system cannot obtain DNS services from the network. 

To resolve this problem, follow these steps. Connect to the console if you cannot connect by 

using SSH.

Do one of the following:

Set up the name servers properly by editing the /etc/resolv.conf file.

Re-execute the Setup.

Verify that the system can obtain DNS services from the network by entering the following command:

 

where <dns-name> is the DNS name of a host on the network that is registered in DNS. When you enter 
this command, it responds with the IP address of the host.

If the system cannot resolve the DNS names to the IP addresses, the DNS server is not working properly.

Resolve the network DNS problem.

If the system can resolve the DNS names to the IP addresses but you still cannot connect to the system 
by using SSH, contact the Cisco TAC for assistance.

You cannot connect to the system by using Telnet when the system is connected to the network.

This problem can occur if the Telnet service is disabled on the system.

To resolve this problem, use SSH to connect to the system.
