| Subject: | Invalid IpAddress length (8 bytes) against 64bit net-snmpd |
Example: performing a get_request for oid: .1.3.6.1.2.1.4.21.1.7.0.0.0.0
will result in an error if performed against a net-snmpd server <4.0:
"request error: Invalid IpAddress length (8 bytes)"
net-snmp versions <5.4 have a bug where IpAddress is 8 bytes instead of
4 on 64bit hosts:
http://www.net-snmp.org/about/ChangeLog.html -
5.4:
snmpd:
- fix 8 byte IpAddress in at, ip and route MIBs.
So, what I did was patch Net::SNMP so it works against both good and
"bad" 64bit net-snmp servers.
A patch is attached which works around the issue.
