Top Forums Programming UNIX network programming execution problem Post 302946538 by rbatte1 on Wednesday 10th of June 2015 05:53:09 AM

Well, the target IP address you have given is the local host, 127.0.0.1 so that will come back to your own machine, but what port is your program connecting to? You will need to check that you have a server process listening to that port on either 127.0.0.1 or generally on all ports.

The output from netstat -na | grep LISTEN may help you see what is actually being listened for before you try to connect.

Can you share the code so someone (probably with more skill than I) can comment?



Thanks, in advance,
Robin

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.
