Script to check if host key authentication is setup

Hey all,

I have a script that I use for some automated installs. Unfortunately for the script to work the server that it's running from needs to have host-key authentication setup to the target server. If it isn't setup beforehand and the script is executed the install partially completes and gets very messy.

Currently I have it set to ask the user to confirm host key auth is setup before continuing but that takes away the automated functionality I'm hoping for. Does anyone here knows of a way to "test" whether or not host-key auth is setup correctly before starting the install. I'm sure it's possible with expect but I'm hoping to avoid using that method.

Thanks in advance!

NAME
brlapi_connectionSettings_t - Settings structure for BrlAPI connection. SYNOPSIS
#include <brlapi.h> Data Fields char * auth char * host Detailed Description This structure holds every parameter needed to connect to BrlAPI: which file the authorization key can be found in and which computer to connect to. Examples: brlapi_connectionSettings_t settings; settings.auth='/etc/brlapi.key'; settings.host='foo'; libbrlapi will read authorization key from file /etc/brlapi.key and connect to the machine called 'foo', on the default TCP port. settings.host='10.1.0.2'; lets directly enter an IP address instead of a machine name. settings.host=':1'; lets libbrlapi connect to the local computer, on port BRLAPI_SOCKETPORTNUM+1 See Also: brlapi_openConnection() Field Documentation char* brlapi_connectionSettings_t::auth For security reasons, libbrlapi has to get authorized to connect to the BrlAPI server. This can be done via a secret key, for instance. This is the path to the file which holds it; it will hence have to be readable by the application. Setting NULL defaults it to local installation setup or to the content of the BRLAPI_AUTH environment variable, if it exists. char* brlapi_connectionSettings_t::host This tells where the BrlAPI server resides: it might be listening on another computer, on any TCP port. It should look like 'foo:1', which means TCP port number BRLAPI_SOCKETPORTNUM+1 on computer called 'foo'. Note: Please check that resolving this name works before complaining Settings NULL defaults it to localhost, using the local installation's default TCP port, or to the content of the BRLAPI_HOST environment variable, if it exists.
