[Swift-devel] ssh test case on pads/beagle

[Michael Wilde]

Alberto, I suspect that the problem is that your SSH key is of a form that's not compatible with the Java SSH library that Swift is using, based on this message: 



Caused by: com.sshtools.j2ssh.transport.publickey.InvalidSshKeyException: Can't read key due to cryptography problems: java.security.NoSuchAlgorithmException: Unsupported passphrase algorithm: AES-128-CBC 


Can you try again with a new key, generated on Linux, using say RSA encryption? Try using one of the recipes for generating ssh keys that are posted on the MCS or CI web sites.

Hello, 


I am trying to run a simpler case than ssh-pbs-coaster test case, and I'm still having the same error. 
Now I am running only ssh test case (/tests/providers/ssh/001-catsn-ssn.swift) 


The command line is: 

swift -config cf -tc.file tc.template.data -sites.file sites.template.xml 001-catsn-ssh.swift 


The output: 

Swift svn swift-r4861 (swift modified locally) cog-r3183

My auth.defaults reads: 



login1.beagle.ci.uchicago.edu.type=key 
login1.beagle.ci.uchicago.edu.username=achavez 
login1.beagle.ci.uchicago.edu.key=/home/Alberto/.ssh/identity 


login1.pads.ci.uchicago.edu.type=key 
login1.pads.ci.uchicago.edu.username=achavez 
login1.pads.ci.uchicago.edu.key=/home/Alberto/.ssh/identity 




and it has been set to 600, I ommited the passphrase line, but it is there, and the passphrase is right because I just verified it in two ways: 
1) by logging to pads and beagle without providing a password 
2) "changed" the password. I the "new" password is the same as the "old" one. 

sites.templates.xml: 


<config> 
<pool handle="ssh"> 
<execution provider="ssh" url="login1.pads.ci.uchicago.edu" jobmanager="ssh"/> 
<filesystem provider="ssh" url="login1.pads.ci.uchicago.edu" /> 
<profile key="jobThrottle" namespace="karajan">0</profile> 
<workdirectory>/home/achavez/swiftwork</workdirectory> 
</pool> 
</config> 


config file: 


wrapperlog.always.transfer=true 
sitedir.keep=true 
execution.retries=0 
lazy.errors=true 
status.mode=provider 
use.provider.staging=true 
provider.staging.pin.swiftfiles=false 
foreach.max.threads=10 
provenance.log=true 




I also tried a simpler SwiftScript: 



type filemsg; 


app (filemsg output) hello(string s) 
{ 
echo s stdout=@filename(output); 
} 


filemsg myfile<"dogcatdinosaur.out">; 
myfile = hello("dog,cat,dinosaur"); 


and I get the following output:

The following errors have occurred:

any thoughts on this?
