TFTP: error code 11 received - 18025

Hello Friends, I'm trying to backup a Cisco IOS image to my Vista 64 bit PC. I am using the  Tftpd32 software. I tried Solarwind, but that one wouldn't even start and threw "someone else is using port 69" even though there was no other TFTP software running. So that one wound up in the trash.

Now, with Tftpd32 in hand, I can ping both ways. I was able to accomplish uploading once, with "copy flash:c1700-blah-blah.bin tftp" command issued on the router. After complying one time, the tftp software refuses to work again, throwing out "TFTP: error code 11 received - 18025" messages. With some tinkering, I was able to change the error to a "TFTP: error code 2 something". Couple of Uninstall-reinstall later, it was back to "TFTP: error code 11 received - 18025". Is this just the usual Vista 64 garbage? There are no settings to change on the Tftp software, except specify an IP. Why would this crap work once and then stop? Thanks!

I have so many issues with vista and TFTP software. Do you have windows firewall on? Could be blocking the communcation attempt on port 69.

the other thing ive seen is that the tftpd software not having correct permissions to write to the filename, so i had to create a 0 byte file with the correct name before it'd download..


Ok I found a rogue TFTP software still running on my computer even though I uninstalled it long time ago. (Sorry Solarwinds, turns out your error message was correct.) It's called WinAgents TFTP Server 4. I am currently trying to get rid of it, but having a difficulty because Windows still lists the program in the program list but wouldn't uninstall it saying it is not installed. The darn thing runs upon startup, and I can't stop it in the task manager because it tells me I don't have access to do that.

Can you disable it from running at startup?

Check registry keys to remove it from starting up at logon:



I managed to stop the rogue process, so now I get this on the router:
TFTP: error code 2 received - 16739

%Error opening tftp:// (Permission denied)

And this in the TFTPD32:

Connection received from on port 55501 [17/02 10:20:06.025]
Write request for file <router-confg>. Mode octet [17/02 10:20:06.027]
File <router-confg> : error 5 in system call CreateFile Access is denied. [17/02 10:20:06.029]

Open in new window

Permissions issue now, double-check the permissions of the image on the TFTP server. Chances are they are not set... let's hope so.


Ok, after getting rid of the pesky WinAgents TFTP server, I booted up Solarwinds and it worked like a charm while the Tftpd32 failed. Here's the router output:
Router#copy flash:c1700-advsecurityk9-mz.124-13a.bin tftp
Address or name of remote host []?
Destination filename [c1700-advsecurityk9-mz.124-13a.bin]?

Tim, how do I access those registry keys? I ran the regedit but it doesn't list them nor is finding them. I was able to stop the WinAgents tftp service process with a maintenance proggie, but it is back on after the restart even though I uninstalled WinAgents with an uninstaller proggie and deleted all winAgents registry keys. WinAgents comes back from the dead again. How do I get rid of it for good?

Can you find the executable for the file and trash it???

The file and the directory are not there anymore, I even deleted all WinAgents keys from the regedit. But somehow the tftp service that the proggie initiated still runs. To stop it, in the task manager, I found there is a Services button. It calls up the Services explorer window in which all the running services are listed. I found the pesky WinAgents there and disabled it (there is no option to delete it), hopefully it sticks.

Great! That's available from msconfig too, with other information regarding startup programs. Try it out and let me know1
