RE: snmpget and snmpwalk return corrupt string instead of hex string when MAC address starts with non zero
Randall C Grimshaw
Dave:
Thank you for your assistance, it is much appreciated.
The -0x parameter does work for the snmp apps. Ultimately I am also using PHP which uses the libs so a am still stuck. Removing the RFC1213-MIB file does not appear to be a solution. I am setting up a test to attempt forcing the IP-MIB you mentioned.
Do you have any other suggestions

No - that's not what is happening.
The problem is not with how the data is encoded by the agent.
Rather it is with how the results are being displayed by the client tool.
If you run the command using the option '-Ox', this will force output in
hex format, and you should see the value as expected.
Alternatively, if you remove the RFC1213-MIB file, then the client tools
ought to pick up the IP-MIB definition instead, which includes the correct
DISPLAY HINT to display this value as a hex string automatically.

I guess I do not understand the DISPLAY-HINT association. The type is clearly defined in the MIB files and do not know why it would not be considered a bug that a MAC address that does not start with 00:xx:xx does not display properly.

Randall C Grimshaw
When I tried to remove the RFC1213-MIB the apps fail.
ip.ipNetToMediaTable.ipNetToMediaEntry.ipNetToMediaPhysAddress.443: Unknown Object Identifier (Sub-id not found: (top) -> ip)
The only DISPLAY-HINT I can find in IP-MIB to use as an example is for Ipv6AddressIfIdentifierTC
I tried to add a hint to the RFC1213-MIB under ipNetToMediaPhysAddress and it also reminds me that I do not know what I am doing.
Bad format of optional clauses (DISPLAY-HINT): At line 1314 in /usr/local/net-snmp/5.5/share/snmp/mibs/RFC1213-MIB.txt
Bad parse of OBJECT-TYPE: At line 1314 in /usr/local/net-snmp/5.5/share/snmp/mibs/RFC1213-MIB.txt
ip.ipNetToMediaTable.ipNetToMediaEntry.ipNetToMediaPhysAddress.443: Unknown Object Identifier (Sub-id not found: (top) -> ip)
But I really have attempted each of your valued suggestions. (And I have been scanning the documentation in earnest also).
Thank you for helping.
Randy

Note that you are picking up the definition of the ipNetToMediaTable objects
from IP-MIB. This references the type PhysAddress from SNMPv2-TC,
which does include the necessary display hint.
Randall is picking up definitions of ipNetToMediaTable from the older
RFC1213 MIB, which does not include this hint. So the library has to
fall back on guessing whether a given string is printable or not - and
this decision depends on the exact value it receives.
That's why I suggested he try removing the RFC1213 MIB, and
using the IP-MIB (plus supporting infrastructure).
(Which was promptly dismissed as "not being a solution" - hmmm....)
Randall C Grimshaw
In another message: I recently discovered that editing the IMPORT line in RFC1213 works... I wonder if this is related to my compiling with --enable-old-features
Thank you.

You need to remove the RFC1213-MIB *and* install the IP-MIB, etc.
One without the other won't work.
This ought to be set up automatically as part of installing the Net-SNMP
package. The fact that the IP-MIB currently isn't being found is a bad sign.
> I tried to add a hint to the RFC1213-MIB under ipNetToMediaPhysAddress
No - that's not a sensible approach.
Concentrate on getting the standard MIBs loaded properly.

What does
'ls /usr/local/net-snmp/5.5/share/snmp/mibs'
report?
Randall C Grimshaw
Thank you again. I ran the -Dparse-mib command as you suggested. It is interesting that IP-MIB is identified as Module 28 but not parsed for ip.x.x.x RFC1213-MIB is Module 52 and may have commandeered the association.

Pragmatically - if it works for you, then fine.
But it's a gross hack, mixing SMIv1 and SMIv2 definitions.
The Net-SNMP tools are relatively easy-going, and won't
mind about this, but it may well break more strict applications.

Very unlikely.
If you want to solve this properly, I'd start by removing the RFC1213 MIB
file again, and then running the command with the option -Dparse-mib
This will print out debugging information about the loading and parsing
of MIB files. That might give some indication about why the IP-MIB
file isn't being read.

ls: /usr/local/net-snmp/5.5/share/snmp/mibs/.index: No such file or directory
And still when I remove RFC1213-MIB it knows the index is outdated...???
Just for grins I downloaded the source again and compared the IP-MIB.txt and it is intact. It does differ from an older UCD install while RFC1213-MIB.txt is unchanged.

But what does this output look like if the RFC1213-MIB is *not* present
in the mibs directory?
It might also be worth removing the file
/usr/local/net-snmp/5.5/share/snmp/mibs/.index
in case this is confusing the parsing code.

Comparing this with the output that I see, IP-MIB is Module 16, while RFC1213
isn't pulled in until Module 58.
I'm increasingly suspicious about the MIB index file....

It was rebuilt when I removed RFC1213-MIB.txt
I removed the index (0) and restored RFC1213-MIB.txt

Outdated rather than missing?
That implies that there is an index file somewhere....
(Maybe under /var/net-snmp?)
The debug flag '-Dmibindex' might help here.
Another thing to try - what happens if you explicitly load the IP-MIB?
Either
snmpwalk -m +IP-MIB .....
or
snmpwalk .... IP-MIB::ipNetToMediaPhysAddress
Maybe this MIB isn't part of the default list.
Do you have a file snmp.conf (note - *not* snmpd.conf) somewhere?
Maybe in ~/.snmp or /usr/local/net-snmp/5.5/share/snmp/
or /usr/local/net-snmp/5.5/etc ?
The debug flag '-Dinit_mib' will show the list of MIBs that is being loaded
automatically.
Randall C Grimshaw
It is most interesting that it continues to look in the RFC1213-MIB even when removed....

in snmpd.conf
Instead of a password and nothing I have tried has worked.
For example:
I tried the following:
createUser v3user9 MD5 0x2131415161718191a1b1c1d1e1f12232 DES
0x2131415161718191a1b1c1d1e1f12232
where I want the authkey =
21.31.41.51.61.71.81.91.a1.b1.c1.d1.e1.f1.22.32
Unfortunately I think net-snmp is taking the 0x.. as a "password string"
and creating an auth-key and priv-key from it.
I verified this by reading the authkey of this user via a call to:
uptr = usm_get_user(engineID, engineIDLen, newName);
and the authkey for this entry is:
e8.5f.42.d5.83.91.25.8b.6c.ed.dc.b4.80.7c.a2.2c
not
21.31.41.51.61.71.81.91.a1.b1.c1.d1.e1.f1.22.32
Unfortunately not even the
e8.5f.42.d5.83.91.25.8b.6c.ed.dc.b4.80.7c.a2.2c key worked when I placed
it as the key in the Mg-soft mib browser I get stats-wrong-digest
authentication error. So not exactly sure where the key is in the code.
I am able to use an authkey (not a password) using Mg-soft and a non
net-snmp agent - which leads me to believe the way I specified the
auth-key in the snmpd.conf directive was not correct.
I would be very appreciative for any info you can provide to help me
accomplish this.
Thanks for your time.
Randall C Grimshaw
You were correct. Removing the --disable-agent option fixed the problem.
Thank you.

$ man snmpd.conf

createUser ....
:
If you want to generate either your master or localized keys directly,
replace the given password with a hexstring (preceeded by a "0x")
and precede the hex string by a -m or -l token (respectively).
:
Have you tried using the -l or -m options?
