troubleshooting help needed

SephStorm

I have 2 1721 routers that I just got, and I need help troubleshooting, and fixing them.

1 of them had a corrupted or damaged IOS, it booted straight to ROMON. I needed an IOS image to resore it with, but of course the DL from cisco required a contract.

I was going to copy the IOS from the other, but the configuration was still in the router, and while going through the process of resetting it, it looks like I f*ked up. I can tell you I performed a reset, then I restored to defaults, when it rebooted, it had a password on it again, but not the password from the previous config. I reset it again, and looked at the startup conf (but it appeared to be missing. Before I could copy run start, my term appeared to stop responding. After restarting, Both routers just blink OK at me. I cannot see anything from them on my terminal, not even a boot sequence.

Help.

EDIT: switched out the rollover, and I can get into 1 dev, ATM, will update.

All devices are showing on TT now, maybe the cable went bad, suddenly?

anyway, I see that I might be able to copy the IOS to the PCMIA card, but I dont know if this model has one, or where it is/how to replace. Thoughts?

what you want to do is download a TFTP program and then transfer the IOS from the working device to your PC. Then TFTP the IOS to the other device. I use solarwinds version at home

hi, and thanks for your help.

I am almost there, but I am stuck at copying the image. I am usingtftpd32 (Solarwinds supposedly has some security configs that could give me problems)

neither router has IP addresses or anything, so I am attempting to configure it now... wish me luck. I only need a connection from the router to the PC right? Not to the internet?

correct, you need the router and your pc on the same subnet, plug both into a switch or connect directly together with a crossover cable

rommon 3 > set

IP_ADDRESS=172.18.16.76
IP_SUBNET_MASK=255.255.255.192

Sorry to have so many basic questions, but urg...

EDIT: I could set the ip on the PC once I connected the switch to my (internet) router now I can ping from the pc to the (Cisco) router, and to the internet router, and the router can ping the internet router, but I cant ping from the cisco router to the pc.

What exactly is your "internet router"? and how are all the devices connected?

It's probably the PC firewall -- either disable it temporarily or change the firewall setting to allow ICMP and FTP from the local network.
