Hi Niels,
First of all, thank you very much for your time and help. Taking into
account the tips you gave me, I made the following changes:
I changed the code so that the file opens and closes within each case
(MODE_GET or MODE_SET_ACTION).
I used fprintf function that you said, instead of snprintf and fputs, and
actually is simpler.
And when i open the file, I do so with the mode "r +" to be able to read
then the value.
After making these changes, the SET operation it works (which writes in a
text file), so then I added also the GET operation (which read in the same
text file) and it works too! :)
As for adding some debug output, I do not know where I can find the records.
For example, I understand that the next block of code writes debug messages:
DEBUGMSGTL (("example_scalar_int"
"Initalizing int scalar example. Default value =% ld \ n",
example1));
Also, I run the agent through the snmpd daemon, which runs the binary with
the following parameters:
SNMPDOPTS = '-Lsd-Lf / var / log / snmpd.log-p / var / run / snmpd.pid'
start-stop-daemon - quiet - start - oknodo - exec / usr / local / sbin /
snmpd \
- $ SNMPDOPTS
I have checked the log file and this is what i get:
$ cat /var/log/snmpd.log
getaddrinfo: start Name or service not known
Error opening specified endpoint "start"
Server Exiting with code 1
Considering all this, could you help me find where logs are being saved?
I'm running the agent correctly?
>From already, thank you very much again.
Greetings.
