I still haven't seen any debug results or packet captures of 
cases where this doesn't work and since I can't reproduce the 
problems myself I'm not making any progress here.

Has anyone else been able to test yet?

Patrik,

I had a chance to test your latest revision of the script and tftp
library, and it seems to work fine for me.  I even dug up another Cisco
box to run against, and got good results from that one as well.

Ok, I'm happy to hear that.


The two Cisco boxes are quite different, and it takes one of them about
twice as long to build the running config and connect back to the TFTP
server.  This means that I haven't really been able to test how
effective the concurrency of the library is.  However, it seems to have
no problems handling the files as they come in:

I've been emulating several identical routers and got data back more or less at the same time and it seems to work good 
for me to.

Let me know if you want more details or would like to see any additional
output.

Thanks for testing! I'm happy with the details. As far as I can tell, the script now works as intended.


Thanks,

Thomas
