No SNMP response received before timeout #7

Closed AllenX01 closed 5 years ago

AllenX01 commented 5 years ago

Hi, From a beginner: A failure like this "No SNMP response received before timeout" in case of the below command input: 1）snmpget.py -v3 -u usr-sha-aes -l authPriv -A authkey1 -X privkey1 demo.snmplabs.com IP-MIB::ipAdEntBcastAddr.\"127.0.0.1\" 2）snmpget.py -v3 -l authPriv -u usr-md5-des -A authkey1 -X privkey1 demo.snmplabs.com sysDescr.0

Do I need to do some network configuration？ My OS: VMware +Ubuntu16.04

Hope you help me out.

I suspect a firewall problem. Exactly the same command works for me:

$ snmpget.py -v3 -l authPriv -u usr-md5-des -A authkey1 -X privkey1 demo.snmplabs.com sysDescr.0
SNMPv2-MIB::sysDescr.0 = DisplayString: Linux zeus 4.8.6.5-smp #2 SMP Sun Nov 13 14:58:11 CDT 2016 i686 
$

You may want to enable some debugging to see if anything comes back to you:

$ snmpget.py --debug io  -v3 -l authPriv -u usr-md5-des -A authkey1 -X privkey1 demo.snmplabs.com sysDescr.0
