Verify you firewall is not blocking the TFTP connection.

Firewall is off!

One thing I noticed when I was playing around and upgrading / backing up ios is that some tftp servers require you to run them as an administrator to work properly. For example, in Windows 7 64 ultimate, I could download from my tftp all day long, but I couldn't back up files to it unless I ran the program as an administrator. This took me a little bit to figure out. That may not be your issue, but thought I'd pass it along just in case. For reference, I was using TFTPD64 server at the time.

Also, make sure your ios is in the root directory of your server. Otherwise it won't be able to find it. Other than that, maybe some other folks here will have some thoughts.

I've tried but t's not working.Another ideea please!

What's the mask you're using on the pc? If that matches the router, I'd try using another tftp server (such at tftpd) and seeing if that works. I've never messed with solarwinds, but if you have your router / pc configured correctly, there's not much that can go wrong. I'd also double check that all firewalls are off, including windows firewall if you're running vista/7. Might post your running config here for people to look at.

Also, maybe a dumb question, but you do have enough space for the ios you're wanting to download, right? I believe you can bypass the deletion of the current ios and try to download a file, at which point it will simply time out when it runs out of room. I believe that happened to me at one point when I was having so much fun recovering my ios and trying to troubleshoot some bad ram.

Anyway, might copy and paste the running config and the exact error you're getting. Someone will have an answer, I'm sure.

First i want to back up the current IOS.

How are you connected to the Router? Are you going via a switch? If so, cut out the switch and connect to the router directly from the laptop. Obvious I know but make sure you use a cross over cable and not a straight through.

zimskiz

I'm directly connected with a cross over cable to the router.

Try a straight-through

zimskiz

Still the same problem.

Monkerz

Open a command prompt on your PC and run a "netstat -ano" Verify that nothing is using UDP 69. If it is, find the PID in the column to the right and open your task manager to find what it is and kill it.

I had this problem a few times when trying to throw a quick config on a sup engine. Turns out I had solarwinds tftp running while I was trying to use tftpd32.

zimskiz

No, nothing it's using UDP 69.

Monkerz

Stupid question, but do you have your TFTP client open while attempting this copy?

Open the client and run that command again to see if it is actually opening the port on your PC.

zimskiz

Yes i have the client open but i can't find the ip with the port in use.... like 192.168.100.10:69 ...there isn't such thing.

Monkerz

Should appear as 0.0.0.0:69 if it is listening and not being used...

Monkerz

And if you can't find it, it sounds like your TFTP server is malfunctioning. Maybe the Solarwinds TFTP Server service stopped or something.

Download TFTPD32 : an opensource IPv6 ready TFTP server/service for windows : TFTP server and try again.

zimskiz

With this TFTP on cmd appears 0.0.0.0:69....but when i do the commands for copy IOS the netstat -ano still display 0.0.0.0:69.
Obivously still not working , same output : %Error opening tftp://192.168.100.10/c2600-i-mz_122-24 (Timed out)

Monkerz

Try copying something different from your router to your PC. Try 'copy start tftp' and follow the prompts.

Does your IOS image have .bin at the end?

zimskiz

It doesn't have .bin at the end.

Monkerz

Were you able to copy your startup-config?

zimskiz

Sorry for last night, connection problem.

I've tried with running-config but i have the same problem!

SteveO86

Do you have any type of security software on your PC that could possibly be blocking port 69?

As mentioned before you will probably want to append the .bin when typing in the file name. The IOS file should have a .bin at the end of the file. (You might have to turn on file extension to see it)

zimskiz

I've figured it out with another laptop, seems like i have a security issue but i don't know from what.

Thank's you all guys!

alxx

sure you were running tftp as an adminstrator ?
or didn't have windows firewall running ?

zimskiz

Yes, running tftp as an admin and firewall off; i'm very sure.
