[mrtg] cfgmaker failing

You seem to have a typo in the IP address:

[root at tuxnldds01 tuxnldds01]# cfgmaker --global 'WorkDir:
/var/www/html/tuxnldds01/' --global 'Options[_]: bits,growright' -output
./tuxnldds01.cfg 10.10.110.31

Uses 10.10.110.31

[root at tuxnldds01 tuxnldds01]# snmpwalk -v 1 -c public 10.10.100.31
1.3.6.1.2.1.1

Uses 10.10.100.31

Either the first is using the wrong IP address, or your second is testing
the wrong IP and the original IP is still blocking by ACL or community.

Subject: [mrtg] cfgmaker failing

Hi, 

I’m having problems getting cfgmaker to read a linux box. This is running
on a CentOS box as a yum installed binary. 

I do have this system already reading data from a Cisco switch, so I suspect
the binaries are working fine.

Any ideas would be appreciated.

The error looks like snmp is the issue:

[root at tuxnldds01 tuxnldds01]# cfgmaker --global 'WorkDir:
/var/www/html/tuxnldds01/' --global 'Options[_]: bits,growright' -output
./tuxnldds01.cfg 10.10.110.31

SNMP Error:

no response received

However snmpwalk against that mib seems to work just fine:

I have a very simple snmp.cfg:

[root at tuxnldds01 tuxnldds01]# more /etc/snmp/snmpd.conf

rocommunity  public

syslocation  "Tucson DataCenter"

syscontact  nccops at vaisala.com
