Hi,
 
Correction.... there is no error but I only can see this in my config
file, why cfgmaker does not generate the complete config file?

Hello,

 

Try taking the "context" out of your contextengineid line ( ie.
--contextengineid=800000090300000ED733EC1B)

Hi, 

I am trying to use cfgmaker to generate the mrtg config file. Below is
my cfgmaker command line: - 

/usr/local/mrtg-2/bin/cfgmaker / 
--global WorkDir:/usr/local/apache/htdocs/mrtg/WAN/GSR/gsr2 / 
--global "Options[_]:bits,growright" / 
--enablesnmpv3 / 
--snmp-options=:::::3 / 
--username=readonlyuser / 
--authproto=MD5 / 
--authpassword=readonly123 / 
--contextengineid=context 800000090300000ED733EC1B / 
--output /usr/local/mrtg-2/cfg/mrtg_gsr2.cfg a.b.c.d 

But I got the following error: - 

SNMPopen failed: Unable to resolve UDP/IPv4 address

Tried to omit "--contextengineid=context 800000090300000ED733EC1B" but I
got the following error: -

My snmpget is working: -

MRTG version: mrtg-2.16.1 
Net::snmp version: 5.2.0 
Net-snmp version:5.4.1

Any help would be much appreciated.
