[Swift-user] Error with SSH and SSH-CL

[Scherer, Justin C.]

I have been trying to get the simple hello.swift script to run on a remote host that I have set up with another researcher. I will post my sites.xml, config file, and tc.data files along with this message. After going through all of the steps to get ssh to work, I get the following error  for running it in ssh mode:

RunID: 20150330-1550-ut0jr8rf
Progress:  time: Mon, 30 Mar 2015 15:50:36 -0500
Execution failed:
	Could not initialize shared directory on remotehost
Caused by:
	org.globus.cog.abstraction.impl.file.FileResourceException: Error while communicating with the SSH server on 146.137.66.189:22
Caused by:
	Invalid private key or passphrase
Caused by:
	Can't read key due to cryptography problems: java.security.NoSuchAlgorithmException: Unsupported passphrase algorithm: AES-128-CBC
	greeting, hello.swift, line 9

I tried both the dsa algorithm and putting in the rsa algorithm for this. Here is my sites.xml for this:

<config>
  <pool handle="remotehost">
    <execution provider="coaster" jobmanager="ssh:local" url="<blanked out for obvious reasons>"/>
    <filesystem provider="ssh" url="146.137.66.189"/>
    <profile namespace="karajan" key="jobThrottle">0</profile>
    <profile namespace="karajan" key="initialScore">10000</profile>
    <workdirectory>/home/swift-user/temp</workdirectory>
  </pool>
</config>

also, here is the tc.data file:

#This is the transformation catalog.
#
#It comes pre-configured with a number of simple transformations with
#paths that are likely to work on a linux box. However, on some systems,
#the paths to these executables will be different (for example, sometimes
#some of these programs are found in /usr/bin rather than in /bin)
#
#NOTE WELL: fields in this file must be separated by tabs, not spaces; and
#there must be no trailing whitespace at the end of each line.
#
# sitename  transformation  path   INSTALLED  platform  profiles

localhost	sleep	/bin/sleep	null	null 	null
remotehost	echo	/bin/echo	INSTALLED	INTEL32::LINUX	null

and the configuration file is exactly like what is shown in the documentation.

If I try to do the ssh-cl interface, I get the following error:

There is no shared folder, so I have to use scheduling.

I am using Swift version 0.94.1 from the main website. Any help is appreciated. Thank you!
