Disaster 877 has only romon and conflict ip, need help?

Postby Guest » Wed Oct 21, 2009 5:50 am


Hi

My mistake is to format my flash. After 1 day to read without successfull finding solution. I really need your expert opinions.

I download new IOS and decide to format flash. After that I can only have rommon prompt.

I read some articles. I download tftp server like Solarwinds or tftp32, install it. Then I manual set ip to my network card like 10.1.0.1 with subnet: 255.255.255.0, gateway: 10.1.0.2. I start tftp program and it always have the same ip of my network card, that means ip of tftp server is now: 10.1.0.1.

In console, I set:

IP_ADDRESS:10.1.0.1

IP_SUBNET_MASK:255.255.255.0

DEFAULT_GATEWAY:10.1.0.2

TFTP_SERVER:10.1.0.1

TFTP_FILE:124_20T.BIN

Result: from console I always get : Operation terminated [TIME OUT].

Specially, in the log of tftpd32 I have the message: error 10054 in system call recv An existing connection was forcibly closed by the remote host.

I have the same problems when trying to use xmodem option, then I get the same message time out everytime.

If you have any opions, please advice me step by step to recover my IOS to flash.

Thanks in advance

Hi,

I'd say, ensure your TFTP server doesn't have a firewall blocking the traffic.

Also, you need to ensure you are using the first/loweest numbered interface for connectivity.

See the following for more detail on downloading from TFTP within ROMMON:

Hi

Thanks for response

But my windows firewall has turned off.

And I use crossover cable to connect to FE0.

Any ideas

Hi, you have the router IP_ADDRESS set the same as the tftp server.

Change the router to IP_ADDRESS=10.1.0.2 and DEFAULT_GATEWAY=10.1.0.1 and try it again.

Hope this helps.

Hi

Thansk for response.

I know the fact that I have IP_ADDRESS set the same as the tftp server IP. But I cannot change it. Somewhere on internet, they say it's O.K, I don't know it's true or not.

Here're my steps:

1. Get IP_ADDRESS manually to have:

10.10.10.2/255.255.255.248 with gate: 10.10.10.1

2. Double click tftp32 or Solarwinds tftp free, all of them get always the ip of my IP_ADDRESS. That means 10.10.10.2

3. In console set up IP_ADDRESS, IP_SUBNET_MASK, DEFAULT_GATEWAY, TFTP_SERVER, TFTP_FILE, then finally press Enter when you re typing tftpdnld -u.

Result: Time out in console, windows popup Ip conflict, tftp32 has above message.

2nd chance:

1. Setup IP manually like: 10.10.10.2/255.255.255.248 Gateway: 10.10.10.1

2. Turn on tftp server, it will get the same ip of my IP_ADDRESS: 10.10.10.2

3. Setup again manual IP like you said before to have: 10.10.10.1/255.255.255.248 gateway now is 10.10.10.2

4. Go to console setup as above details.

Result: it doesn't work too. the same message is Time out and ip conflict.

Even with xmodem, I still cannot get it. It will have always Time out or cannot connect. But I still have character clearly Rommon 1> and other info in my display console.

Any ideas.
