I finally got back to this. Patch attached. It's definitely a bug in
the agent.
Be sure to back out the last patch before applying this one, or:
$ cd zenossinst
$ rm -rf build/pysnmp
$ cp patch-from-eric externallibs/pysnmp-3.4.3.patch02
$ make pysnmp-install
Restart Zope, and Collect Configuration. Let me know if it works.

Hello Eric!
I try to change the version of SNMP from v1 to v2c but also fails with
the same error, and later no appear routes, ipServices...
So i try the patch and restart, and now message error doesn't appear but
a TraceBack appear:
Traceback (most recent call last): File
"/usr/local/zenoss/Products/DataCollector/ApplyDataMap.py", line 48, in
processClient datamaps = plugin.process(device, results, log) File

"/usr/local/zenoss/Products/ZenUtils/IpUtil.py", line 94, in maskToBits
return int(netmask) ValueError: invalid literal for int(): ΓΏ
Later zenoss don't save IpServices and Interfaces information.
Thanks! Regards!

Hi,
I'm fairly certain this is a bug in your SNMP agent. The value in
question has an OID:
1.3.6.1.2.1.4.21.1.1.0.0.0.0
I believe this refers to the default route. The encoded value for
this is:
"@\x08\x00\x00\x00\x00\x00\x00\x00\x00"
This is the part that fails to decode. The "@" is '0x40' which fails
to decode. Basically, it's looking for value which can be things like
a string, or a number, or an IP address. Each kind of value has an
encoded type which should be in the lower 5 bits of 0x40. A value of
zero is undefined for SNMP v1. You could try SNMP v2 against these
devices and see if that fixes the problem.
I've attached a patch to pysnmp to allow this response from an SNMP
client. Give it a try:
$ cd $ZENHOME/lib/python/pysnmp
$ patch -p0 < /the/patch/attached/in/this/mail
Be sure to restart Zope after patching.

You could try SNMP v2 by changing the SNMP

....
Next to try to collect information, no interfaces, no routes and no
ipServices appears in OS.
I check that this error appear only with 64 bits Machine's and reading
log file of net-snmpd appear the next error: snmpd[20117]: send
response: Error building ASN.1 representation (build int size 4: s/b 8).
x86 arch don't have problems.
I read that there are a patch for net-snmp for 64 bits machines for
CentOS... (http://bugs.centos.org/view.php?id=997) but i try it and it
doesn't work. Only delete de error message of log file but no appear
interfaces, routes and ipServices in OS.
Some idea? It's problem of VServer? It's problem of Net-SNMP and 64 bits
machines?
Regards!

Hello again!
snmpwalk command works well, i tried it yet. Server is HP, so
zPropertiers may not modify.
I discover another thing important, i try to collect information of
another machine (linux one) or another device that i had recollected
yet, but appears the same error.
so... it's stranger but i'll try to reinstall and try again!
thaks!

Hi,
make sure windows system is reachable with snmp.
check with snmpwalk -p <snmp_secret> -v 1or2c <IpOfWinSystem>.
Have you installed Informat SNMP on the Windows box?
If the windows system is no HP or DELL, please add HP|DELL to
zProperties->zCollectorIgnorePlugins.

An: General discussion of using zenoss system
Betreff: [zenoss-users] Collecting Data Fails
When i try to collect data from a Windows Machine (Windows 2003
Server) it's fails. It's appears into web page when i collect
information of a device...
Zenoss is installed into Gentoo Linux 2006.0. Version of Zenoss is
0.22.0.
Message Error is :
Traceback (most recent call last): File

Note that Zenoss try to collect the information and later don't
save changes.
