Hello,

In the frame of PerfSONAR bundle 2.1 deployment, I'm currently testing TELNET/SSH 1.2 MP web services
However, I'm facing 2 major issues and I would need additional user experiences.

1) The first issue is that I can retrieve command result through CISCO/TELNET (login/password) method
but CISCO/SSH (login/password) method does not work.
==> I tested CISCO/SSH method in both production and testbed environment but no luck.
Please find hereattached to this mail the log in catalina.out file

2) Second issue, in CISCO/TELNET (and maybe SSH) mode, the web service does not release the vty properly after having executed the command.
==> The direct consequence is that the router is running out of VTY access and the router is no more accessible.
==> The only way to release the VTY is to either issue "clear line vty xx" command through the router console port access or to stop and start the TELNET/SSH MP.


There might be a feature which leave the connection open for some times. This was suggested by Simon Leinen for fastening the communication with the router. A connection is open and is left open for few minutes as when a problem is being troubleshooted, you often send multiple commands to a router. Now I would expect the telnet/SSH MP to keep using that opened session.
I am not sure that it is what creates the issue you are observing.

Anyone experienced such issues ?

Thanks in advance for your help.
Best regards/Frederic
