scp - Two computers, can only transfer files one way
 

Hello All,

I currently have two computers (one windows one linux) connected to each other via a crossover ethernet cable. Now, each computer can see each other and I can ping both ways. Also, I can ssh into the linux box from windows (putty, cygwin) as well as ssh into my windows machine from the linux box.

Here's the problem: I can send files from my linux machine to my windows machine with no problems doing this:

scp this_file.txt windows_user@10.10.10.11:/cygdrive/c

however, I can't seem to send from windows (cygwin) to the linux machine. Here is what I see at cygwin x-term prompt:

$ scp that_file.txt jqweezy@10.10.10.10:/home/jqweezy
jqweezy@10.10.10.10's password:
Executing /etc/profile ...

Now, it seems like everything went fine. However when I look in /home/jqweezy that_file.txt is not there. Any ideas? I look forward to your feedback.

Regards,
JQ

p.s.
Don't know if this helps, but here is some extra info. Linux machine has only one NIC. Windows has two NICs, one NIC is setup for automatic network detection the other is setup for communication with linux machine via crossover cable (see above).

I suggest you to start scp with the -v option (-vvv is much more verbose if needed) that will print out many relevant messages. I think that from this you will understand at what stage the process stops and why, and solve the problem

okay, here is the actual command i am trying to execute and debug messages it prints out, bold is where i believe it is failing:
