Bingo! I removed the content part of the configuration and it just worked.

 

Thanks!!!

In service.properties:

 

# Group=LS

# Description=Enter the content type of the service

service.ls.service_content_type=sshtelnet mp

 

Should either:

have the value file:

service.ls.service_content_type=file

 

or be removed (if theres no value it defaults to file)

 

This should fix the problem, given I am looking at the right versions of the source.

 

For completeness sake:

service.ls.service_content_type

should have the value of iether: file, xmldb, lssummary or context

and it's a internal service property and should not be changed by end users

(It should be absent in the base2)

 

Best regards,

 

Michael

Hi,

 

I don’t mind upgrading any of the nodes in LHC-OPN. When are they going to be released in the stable repository?

 

By the way, the applications I have installed are:

 

perfsonar-java-xml-ls-1.4-1

perfsonar-java-rrd-ma-3.2-1

perfsonar-java-as-1.2-3

perfsonar-java-sshtelnet-mp-1.3.4.2-1

perfsonar-java-sql-ma-2.2-1

 

The conf files are attached in the zip file.

 

Regards,

The logic responsible for registering to the LS service *is implemented in psbase library which is shared among all the services*. It is *not implemented* in the ssh/telnet mp service codebase.

It means that the problem reveiled here has consequences for *all services* as well!

I should know, as I've made various modifications to the base in the past :-) 

 

That code is fired indirectly by the configuration and depending on how much information needs to be send to the LS the service part that builds on the base will also contain logic.

 

The base itself is not as robust towards incomplete configuration as it should be, meaning it will work fine as long as everything is there but as soon as something is missing you will

end up with obscure error messages. I've tried to improve this in the past, but the base is big and there was the promise of a 'base2'.

 

Is 'service.ls.service_content_type' set and if so what is it set to. (service.properties) It's probably easier to send the properties files but make sure they don't contain any sensitive data

 

>What lines of configuration are missing?

I was guessing, see above

 

> I think the problem is with the compatibility of the versions of services

I doubt anything is being send in the first place, given the type of error.

 

Given, as Błażej Pietrzak indicates, that there is a newer version that is based on 'base2' I'd strongly encourage you to upgrade.

Michael
