Description of problem:
cfgmaker is buggy, does not proper support SNMPv3

Version-Release number of selected component (if applicable):
mrtg-2.14.5-2


How reproducible:
Always

Steps to Reproduce:
1. Setup SNMPv3 configuration in/etc/snmpd.conf
rouser  test auth .1
createUser test MD5 test1234

# service snmpd restart

  2. Check using snmpwalk:
snmpwalk -v 3 -u test -A test1234 -l authNoPriv localhost
=> works

3. Try to generate config

Prereq: install perl-Net-SNMP from EPEL

$ cfgmaker --enable-snmpv3 --username test --authpassword test1234 
localhost:::::3 

(note, "--enable-snmpv3" was changed to "--enablesnmpv3" from 2.14 to 2.16)


Actual results:

# cfgmaker --enable-snmpv3 --username test --authpassword test1234  localhost:::::3 >/dev/null
SNMP V3 requires a --username parameter as part of the User Security Model for router public@localhost:::::3 at /usr/bin/cfgmaker line 121.

Hmm, value is specifed...


Expected results:
Working well


Additional info:

This can be temporary fixed with:

Until upgrade to 2.16 is done (this also renames the option to "enablesnmpv3" as in 2.16).
