Old 2500 for OOB - Not honouring hosts?

Hi,

Picked up an old 2509 from ebay for OOB use, and it is accepting "host" commands, but not able to resolve them?

(config)#ip host test 2008 192.168.2.1

#telnet test
Translating "test"
% Unknown command or computer name, or unable to find computer address

192.168.2.1 is setup on loop0:

#sh ip route 192.168.2.1
Routing entry for 192.168.2.1/32
  Known via "connected", distance 0, metric 0 (connected)
  Routing Descriptor Blocks:
  * directly connected, via Loopback0
      Route metric is 0, traffic share count is 1

tried with no ip domain-lookup and also with ip domain-lookup - Still no joy

telneting to 192.168.2.1 2008 works as expected.

It's running a very old version of ios

#sh ver
Cisco Internetwork Operating System Software

OOB-01-PERTH uptime is 4 minutes
System restarted by power-on
System image file is "flash:igs-g-l.111-7", booted via flash

but all the ios versions available for 2509's  on cisco site require more flash

Any help is greatly appreciated.

Unfortunately, static hosts were borken in 11.1(7) due to CSCdi71096.  This defect was resolved in 11.1(8) and above.

Hi,

Try using the telnet command with the port number as below:

telnet test 2008

also, here is troubleshooting section to go over if the above command does not help

Troubleshoot

This section provides information you can use to troubleshoot your configuration.

Troubleshooting Procedure

Follow these instructions to troubleshoot your configuration.

If you cannot connect to the router of your choice with a name configured in theip host command check:

  1. Check whether the port address is configured correctly.

  2. Verify whether the address (interface) used for the reverse Telnet is up/up. The output of the show ip interface briefcommand provides this information. Cisco recommends you to use loopbacks because they are always up.

  3. Ensure that you have the correct type of cabling. For example, you must not use a crossover cable to extend the length. Refer to the Cabling section for more information.

  4. Establish a Telnet connection to the IP address port to test direct connectivity. You must telnet from both an external device and the terminal server. For example, telnet 172.21.1.1 2003.

  5. Ensure that you have the transport input telnet command under the line for the target device. The target device is the device that is connected to the terminal server.

  6. Use a PC/dumb terminal to connect directly to the console of the target router. The target router is the device connected to the terminal server. This step helps you identify the presence of a port issue.

  7. If you are disconnected, check timeouts. You can remove or adjust timeouts.

    Note: If you encounter authentication failures, remember that the terminal server performs the first authentication (if configured), while the device to which you try to connect performs the second authentication (if configured). Verify whether AAA is configured correctly on both the terminal server and the connecting device.

Here is the doc:

Thanks Reza - Telneting with port number unfortunately makes no difference.

#telnet test 2008
Translating "test"
% Unknown command or computer name, or unable to find computer address

The 2500 seems unable to translate name->IP(Even though host entry is present.)

We have multiple other 2500's setup identically to this one, and have no issues - Only difference appears to be the IOS version on this particular 2509.

As stated - Telneting to loopback IP and port works without problem - It's only the name resolution that is not working.

Eg.

(config)#ip host test2 192.168.2.1

#ping test2
Translating "test2"
% Unrecognized host or address, or protocol not running.

#ping 192.168.2.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 192.168.2.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/4/4 ms

#sh host
Default domain is not set
Name/address lookup uses static mappings

Host                     Flags      Age Type   Address(es)
test                     (perm, OK)  2   IP    192.168.2.1
test2                    (perm, OK)  0   IP    192.168.2.1

Thanks - Does anyone know where I can get 11.1(8)? (This 2500 has minimum flash/dram), so the newer versions will not fit))

How much memory/flash does the router have?  You can still download 12.2 and 12.3 which require a minimum of 10mb memory and 16mb flash for the IP feature set.  You mentioned you had other 2500's that don't have the problem so I assume they are running a different version of software, are you able to use that same version on this router?

Tim

Thanks Tim - Found a 11.3(7) and hosts are now resolving.

much appreciated.
