Hi,

I already installed the SSHTelnet MP from perfsonar 2.2 and in
combination with the Looking Glass client, it worked quite well.
Now, I installed the new Service of perfSONAR 3.0 and I only got a lot
of problems:

1) The Web IF is not working, if I open the URL, the main page appears
like it should,but if I click on any link like Basic Setup, I get this
message:

HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented
it from fulfilling this request.

exception

The log shows me the following:

2) Therefore I configured everything by hand, the service.properties and
the xml file. I also uploaded the file to the eXist database. When I
then open the Looking Glass it depends on my luck whether I get the
configured router and the commands,or if I get a popup with an error
message. So the fact that once or twice I got the list with the commands
I wrote in the xml file, shows that the xml is ok and correctly uploaded
to the eXist database.

3) As I used the SSHTelnet service of perfsonar bundle 2.2, I miss the
option to chose whether to connect by Telnet or SSH in the xml meta data
file. Is there an xml element for this?

I hope I'm not bothering you too much, but I really like the concept of
perfSONAR and I'm trying my best to get the services to work.

Regards,

Christian
