Issue while deploying content to SFTP server

Hi All,

Not sure this is the correct forum to post this but i am running short of ideas on this one and wanted to know if some one has faced/solved this issue before.

We use akamai servers where we deploy the content from our TeamSite servers. We use a workflow which invokes a JAVA class to "put" the content to Akamai server. The content is then purged based on selection in custom instantiation.cfg. The above works fine in our dev and CI TeamSite servers but when the code is moved to TS prod. We see issue.

com.jcraft.jsch.JSchException: Auth fail
at com.jcraft.jsch.Session.connect(Unknown Source)
at com.jcraft.jsch.Session.connect(Unknown Source)
at com.bofa.gcib.cpo.deploy.adapter.delivery.SFTPTest.main(SFTPTest.java:87)
Auth fail

at com.bofa.gcib.cpo.deploy.adapter.delivery.SFTPTest.main(SFTPTest.java:87)

I googled the error but i couldn't find anything helpful. The firewall settings look OK, i can only think there is SSH setting to be tweaked somewhere.

The same code works in other TS servers which makes me believe that the code works fine. I am checking the differences between the servers and only difference is the java version although that is not something which should cause this error.

Any pointers here?

I found this on the web.

[PHP]

if ur getting auth fail error,
then take the putty gen private key and convert it to open ssh format by using import functionality of putty gen.Then use this open ssh format file in java code instead of private key. and also use pass phrase by putting in a file and read as byte array. use it in addIdentity(String,bytearrayof ssh format file,null,byte array of passphrase file)

use proper userid,hostname and port no

This is working

[/PHP]

We are on Solaris 10.

We are on Solaris 10.

Not sure if that will help but still...
Check /etc/ssh/sshd_config. If the following is set to 'no', change it to 'yes', see if that helps.

# Change to yes to enable tunnelled clear text passwords
PasswordAuthentication yes

Thanks Boris and taalgaard for your replies.

We use public-private key authentication and so password authentication entry wont help. I generated the key in SSH format as required by JSch and it works fine in our Dev and CI TS servers, i copied the same over TS prod.so i am guessing there has to be SSH config issue in prod.

I verified the entry sshd_config with the working server and the entry seems to allow authentication based on Public Key and Password. I will look more into this and try setting up logging for ssh and try to restart the service. That might help. Let me know if you have any suggestions.
