Any suggetion on which config files i need to look at to fix this?

[Ivan Krastev]

Run scp with -v option for more info.

Is the ssh service running?

[Wouter Jagers]

Hiya,

"WARNING! The following items has been removed from PATH...."
--> Where is this defined ?

What is your default shell on the destination machine ?

I think it's probably worth it to check your customisations in .bashrc or .cshrc

Cheers,
Wout

Shalom,

service sshd status

or

ps -ef | grep sshd

scp -vvv Post output.

I'm increasingly confident your bashrc/cshrc file is involved.

If I test this on one of my machines I can reprduce your problem: when I add "echo TEST" to my .bashrc on the receiving end and do the scp, I see the TEST output and the file does not arrive.

When I remove this statement from the .bashrc scp works as expected.

When I find out why this is preventing the copy from working, I'll post it as well :-)

Cheers,
Wout

[Wouter Jagers · Accepted solution]

Found it :-)

http://www.openssh.com/faq.html#2.9

If any shell initialisation (.profile, .bashrc, .cshrc, ...) produce any output, which is the case for you, scp will not work.

Cheers,
Wout

this file was the culprit.
