Hi there,

Have a strange issue with synapse snmpsend at the moment. When i do a
snmpget with below it sends indeed the snmp get request out but i do
not get a response:

snmpresult := snmpget(snmpoid, community, snmptarget, ansi_string);

The snmpresult is false. When i use the same OID with the normal linux
snmpget i do get a proper response. I noticed with wireshark some
differences in the snmp packet i.e. the packet length (snmpget synapse
84 bytes packet length; snmpget linux 86 bytes packet length). I
however see the proper OID & community also in the snmpget of synapse.

Could this be a bug or am i missing something ... hope someone has a
pointer in the right direction 

PS written and compiled with fpc 2.6.4 and synapse release 40 on
openSUSE.

I don't have experience with snmp.
But the Synapse release 40 is over 3 years old while Synapse itself is
still being developed. (although the snmpsend.pas is still from 2011)

You could try a newer version at:
http://sourceforge.net/p/synalist/code/HEAD/tree/trunk/
You can use the Download Snapshot button on that page.

Thanks rvk,

While you posted a response i tried to remove my own topic ..

Seems i cannot revoke my own stupid new topic   ,. .. i found the
issue already. The snmp community had a extra space at the end
(mistake when reading the conf file). So resolved 

Anyway, thanks for the tip! I am going to check out the suggested
developments.
