Connect to LMS 3.2 via ssh

I have a 3:de party application that I would like to retrieve inventroy data from the LMS via the commandline interface. I would like to login it to the LMS server (run on Windows 2003 server) via the ssh server already installed on LMS (the SSH-2.0-CSSCPServer_1.2.3)

Who do I configure it to allow external access? (for example I can not find any authorized_keys file on the windows server)

My attemepts to connect (from ubuntu) gives the following output:

awestlund@awestlund-laptop:~$ ssh -vvv administrator@171.23.190.113

On Solaris, I find "casuser" picks up authorized_keys2 from the ${NMSROOT}/.ssh/ directory (which needs to be created first), so you could try your luck putting an authorized_keys file in the equivalent folder on Windows (DRIVELETTER:\wherever-you-installed-LMS\.ssh\). However, the name SSH-2.0-CSSCPServer_1.2.3 makes me suspect it's an SCP-only implementation on Windows, instead of a full-blown SSH server that Cisco could usually find on Solaris, so your retrieval method may have to be strictly SCP, even if the authorized_key part works out on Windows.

Have you considered whether your inventory data export could be accomplished via cwcli?

Yes, I can retrieve the data I like using the cwcli and dcrcli command. But I would like to call them from another server. I have tried on a lab installation (using a third party sshdaemon, and it works fine)

From the startup log from the CSSCP I tink it looks like it supports both scp and ssh:

I would also need output from dcrcli, I can not find any information about a remote API for this cli?

what exactly do you want to do? If you want to access Inventory data from a remote site, you do not need to login to you LMS server. Instead make use of a servlet to access the information. The basic steps are a script (e.g. a perl script) that takes 2 arguments, an URL and a payload file. In the payload file is the command you want to be executed, for details and examples see here:

remote access to cwcli:
http://www.cisco.com/en/US/docs/net_mgmt/ciscoworks_resource_manager_essentials/4.3/user/guide/cwcli.html#wp1099722

there is also a sample script mentioned to use the servlet:

depending on what information you really need, starting with LMS 3.2  there is also the method of accessing database views from a remote site. Have a look at this information:

the main document:
http://www.cisco.com/en/US/docs/net_mgmt/ciscoworks_lan_management_solution/3.2/database_schema/guide/dbviews.html

this is the part about remote access:
http://www.cisco.com/en/US/docs/net_mgmt/ciscoworks_lan_management_solution/3.2/database_schema/guide/dbviews.html#wp83416

and the schema of the exposed database views:
