Bash script for checking if a host is on the local network
I'm trying to write a script that allows you to enter your machine name, and then lets you know if the host is on the local network. Here's what I have:
This allows me to enter my machine name (ubuntu) but doesn't actually let you know if it's on the local network or not (aside from looking at the IP and knowing that it's local).
I asked my TA for advice and after a week, his only response was 'ruptime.'
I'm not too sure how to incorporate that into a script that does what the question is asking. Any help or advice would be appreciated. Thanks!

brlapi_connectionsettings_t
brlapi_connectionSettings_t(3) BrlAPI brlapi_connectionSettings_t(3)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.
