Bug 77365 – Ant scp task not working with openssh-3.9

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Olivier Van Acker 2005-01-10 05:37:52 UTC]

Ant scp task is not working with openssh-3.9 
As soon as ant wants to transfer a directory the following error occurs:

[scp] SSH_MSG_DISCONNECT: 2 Received ieof for nonexistent channel 0.
BUILD FAILED
...
server indicated an error: scp: protocol error: received directory without -r

If I downgrade my sshd to 3.8 everything works fine.
So this error is probably caused by changes in the implementation of scp protocol since openssh-3.9

I als found a patch which adds the -r option to the ant scp task 

Reproducible: Always
Steps to Reproduce:
1.Do an scp task in an ant build file with a <fileset dir=".." /> in it
2.Have openssh-3.9 runnig
3. ant this build.xml
Actual Results:  
Error:
[scp] SSH_MSG_DISCONNECT: 2 Received ieof for nonexistent channel 0.
BUILD FAILED
...
server indicated an error: scp: protocol error: received directory without -r

Expected Results:  
Copy all files and directories to remote server

This error is probably caused by changes in the implementation of scp protocol
since openssh-3.9

I als found a patch which adds the -r option to the ant scp task on:
