Hi all,

I have TFTPd32 running on Windows desktop and I have Router from where i want to copy running config to TFTPd32 server but i can not.

TFTPd32  interface has same IP as desktop PC.I can ping the PC ip from Router and vice versa.

Mahesh,

No need for any setting for tftpd32 just check that services tftp are running in desktop and pure ip to ip connectivity between router and pc.

Hope to help

Mahesh,

As you have confirmed there is no firewall enabled in PC and have you checked Forward port 69 if it isn't open in the firewall. Or whatever port the program requires or whatever port you assign.

If that is also not working as suggested try with other freeware software like solarwinds.

Hi,

-- check the service and open the software (tftp32) whenever you are copying from the router --

If the router and the PC can ping each other then that demonstrates that there is IP connectivity and eliminates the most likely source of the problem. I will suggest a couple of other things that might cause this problem:

- is it possible that between the router and the PC there is some router doing filtering or some firewall that might be denying the TFTP packets?

- is it possible that the router is doing some kind of Policy Based Routing that would forward the ping packets normally (and they would work) but is forwarding the TFTP differently (and it does not work)?

- is it possible that there is a firewall running on the PC that is denying the incoming TFTP packets?

When you initiate the TFTP from the router is there any indication in tftpd32 that it sees the incoming request? When tftpd32 is running and after you have attempted the TFTP have you used the log viewer and does it have any information about the request from the router?

Hi Rick

Thanks for reply.

there is no fw running on pc and there is no policy based routing.

this is error message i get

.....
%Error opening tftp://192.168.1.14/2650xm-confg (Timed out).

When you initiate the TFTP from the router is there any indication in tftpd32 that it sees the incoming request? When tftpd32 is running and after you have attempted the TFTP have you used the log viewer and does it have any information about the request from the router?

Answer is no

Any other ideas?

Thanks

Mahesh,

On you PC, is the TFTP application open? if yes do you see the IP address of the PC assigned to it? If you change IP on your PC.  For example if you were using 192.168.1.1 and the TFTP server was open and now you change it to 192.168.1.2, in this case you have to close the TFTP application and open it again so it take 192.168.1.2 if not it will keep the old one.

Hi reza,

thnaks for reply

thanks

mahesh

Reza Sharifi Sun, 01/31/2010 - 19:56

mahesh,

Try another free TFTP server

I like SolarWinds.

Also are you sure there is no firewall or IPS installed on your PC?

Richard Burts Sun, 01/31/2010 - 21:01

Perhaps it would help us understand the problem better if you could cut and paste to post to the thread the output of traceroute from the router to the TFTP server address, and also the command that you enter to initiate the TFTP, any prompts and responses, and the error generated by the router.

Mahesh,

Is there any firewall between you r tftp server and router and what system is the tftp server running on and If it is unix then ensure the permissions are 666.

Richard Burts Sun, 01/31/2010 - 21:45

Ganesh

The original post was very clear about what platform:"I have TFTPd32 running on Windows desktop". So Unix permissions are not the issue.

Mahesh has said that there is not firewall. But I agree with you that the symptoms sort of suggest some firewall or other filtering is taking place.

Rick,

Thanks for pointing out to right direction ,It was my mistake i should have checked the previous post once again.

Richard Burts Sun, 01/31/2010 - 21:42

Thank you for the additional information. The traceroute results are a bit puzzling. There is not any response showing the next hop layer 3 device and there is no response from thePC. If there is no next hop laver 3 device, does this mean that the router and the PC are locally connected in the same subnet? If so could you post the output of show arp on the router? And can you verify that the MAC address that shows up in show arp is the MAC address on the PC interface (ipconfig /all is one way to get the MAC address)?

If the router and the PC are directly connected and the PC is not responding to traceroute, then I wonder if it suggests that there is a firewall running after all?

HTH

mahesh18 Sun, 01/31/2010 - 21:58

Hi rick,

Thanks again for reply

Yes they are in same subnet.

Also i did sh arp on router

2650xm#     sh arp
Protocol  Address          Age (min)  Hardware Addr   Type   Interface
Internet  192.168.1.10          230   000b.bece.bbc0  ARPA   FastEthernet1/0
Internet  192.168.1.14           11   0040.f418.6d8a  ARPA   FastEthernet1/0***********************************this is mac address of pc
Internet  192.168.1.1             -   000f.8f6d.7e70  ARPA   FastEthernet1/0
Internet  192.168.1.25            1   0019.7db7.c89f  ARPA   FastEthernet1/0
Internet  192.168.1.20          105   000d.65de.ff40  ARPA   FastEthernet1/0

also i did ipconfig /all and verify that pc has same mac-add

Hi

You are copying the running config as seen from the commands.

You try to copy startup-config and let us know the result.also check the windows firewall.

Thanks

Richard Burts Mon, 02/01/2010 - 10:14

Mahesh

This is a strange symptom where the router and PC are on a connected subnet, where the PC will respond to ping but will not respond to traceroute and where copy TFTP does not work.

Perhaps if you would post the config of the router we might find what is the problem.

Hi,

I tried my  other pc it works there fine.

Thanks

Hi,

It works fine from another pc but not from Desktop PC which has IP 192.168.1.14.

thanks

mahesh

Leo Laohoo Mon, 02/01/2010 - 17:43

That's exactly my point.  If it works on any other PC but 192.168.1.14 then there's some application that's stopping it.  To make troubleshooting easier, use a different PC.

Reza Sharifi Mon, 02/01/2010 - 17:49

Hi Mahesh,

Glad you got it to work.  It is defiantly some FW/IPS on your PC.  I have the issue with my laptop. I can ping the router from my laptop but I can NOT ping the laptop from the router and of course TFTP does not work either.  The problem is the corporate IPS application installed on my laptop and even by disabling the services and allowing the TCP and UDP ports, I still have issues.

Hi ,

I know It is a bit of a late replay but I have just come across this problem when i was trying to save the startup- config on to solawind tftp server which is running on my vista laptop.

The solution i find was to turn off the wi-fi on my pc. Wit wifi enabled i was able to ping the server and the router from the pc but the data transfer session timed out.

What i dont undestand though , even with wifi enabled the name of the file i wanted the save ,appeared in the tftp server root file,but the actual transfer failed.

Anyway i hope it helps someone who has this problem.
