You should use 'gtn' as the password when running this for GateIn, however there seems to be an issue with the scp command for CRaSH. I have confirmed this locally for both beta-17 and trunk.
The service provider config file org.crsh.term.sshd.scp.CommandPlugin should be renamed to org.crsh.ssh.term.scp.CommandPlugin under META-INF/services. I have created a JIRA @ https://jira.exoplatform.org/browse/CRASH-22. My guess is this is the root cause of your problem.
The other issue I found is that my scp command appends "--" as an argument before the files, and CRaSH errors out to do parsing issues. This is valid getopt sytax on Unix/Linux machines and have created a JIRA for this as well @ https://jira.exoplatform.org/browse/CRASH-23.
You can either build from source and apply these changes or use the version I have attached until CRaSH is updated. Note the version attached was built from trunk.
Let me know if this fixes your issues.
I tested this SNAPSHOT, telnet is working OK , but now SCP returns a
'no hostkey alg'
Did SSH configuration change in this version ?
Its ok now, restarting the whole stuff did the trick, I sucesfully exported with SCP the root of the JCR, What should I export If I want to move one JCR from one machine to an other ? Is the Root ok ?
