Message: 51468    Hi All,

I am trying to configure Net-SNMP agent in uClinux. I have tried to configure the /user/net-snmp/, but I was not successful. So, I tried downloading the net-snmp-5.0.8 and replaced the existing net-snmp. I have run the ./configure in the /user/net-snmp/ folder. I used the following configure command:

./configure --target=bfin \

--with-cc=bfin-uclinux-gcc \

--with-ar=bfin-uclinux-ar --with-endianness=little \

--enable-mini-agent --disable-debugging \

--includedir="/home/manu/uClinux-dist/uClibc/include" \

--without-kmem-usage --with-transports="UDP" \

--with-mib-modules="mibII snmpv3mibs notification target" \

--with-out-mib-modules="ucd<wbr></wbr>_snmp agent_mibs agentx utilities"

I am using the processor Blackfin561. Configure is not giving any error. Butafter that, when I build the uClinux-dist, I am getting the following error:

make[2]: Entering directory `/home/manu/uClinux-dist/user<wbr></wbr>/net-snmp'

Can some body tell me please where I am doing the mistake.

Message: 51470    why would you attempt to build version 5.0.8 when the version in the tree is 5.2.1 ?  if the newer version doesnt work, then the older one probably wont as well

the reason for your error most likely is the configure failed to generate flags properly.  you'd have to dig through the build system to find out what wasnt set properly.

Hi All,

I am able to resolve the build problem. Now, I am trying to run the snmpd demon on the target board. and I am getting the following error. Can somebody tell me what is the problem?

root:~> snmpd -c /etc/snmpd.conf -f &

448

root:~> /bin/sed: cannot execute

/bin/sed: cannot execute

: bad directory

: cannot redirect shell command

mv: unable to rename `/.libs/448-lt-snmpd': No such file or directory

/bin/snmpd: error: /.libs/lt-snmpd does not exist

This script is just a wrapper for lt-snmpd.

See the libtool documentation for more information.

Any Inputs on the error?

Best Regards,

Manu

Message: 51604    you installed the wrong file ... as the error says, it isnt the real binary, just a wrapper script

you should use `make install` instead of trying to manually copy files

Hi All,

I am able to run the SNMP agent on the Blackfin Board. I am using the following command to run the agent:

root:/bin> snmpd  -c tst &

where tst is the community name.

On the SNMP manager, I am giving the command:

[root@babbage sbin]# snmpwalk -v 1 -c tst 10.201.179.222 system

End of MIB

And getting the End of MIB response.

What is the meaning of this?

I have some more doubts:

1. Also I want to know whether I have to do some thing manually to create MIB on the agent side? If so, how to do it?

2. Where exactly I have to put the snmpd.conf file in the agent side(Blackfin Board)?

3. Is it necessary to run the ./configure, make and make install in /uClinux-dist/user/net-snmp/ folder? or all this will be taken care when I build uClinux-dist by enabling snmpd and net-snmp through make menuconfig?

Any help will be greatly appreciated.

Best Regards,

Manu.

Hi All,

In addition to the above problem, I am also getting the following error when I try to do a snmpget from SNMP Manager(Linux PC) to SNMP agent (Blackfin-561 Board):

[manu@babbage sbin]$ snmpget -v1 -c tst 10.201.179.64 system.sysContact.0

Error in packet

Reason: (noSuchName) There is no such variable name in this MIB.

Failed object: SNMPv2-MIB::sysContact.0

Any idea what is the problem?

Regards,

Manu

Like Mike suggested, if you ask at:

  net-snmp.sourceforge.net/support/contacts.html

you might get some better help, since we are not SNMP experts, and they are.

Before that, I would check out:

  net-snmp.sourceforge.net/wiki/index.php/Tutorials

  net-snmp.sourceforge.net/docs/readmefiles.html

Hi All,

Net-snmp 5.0.8 is working fine on Blackfin uClinux.

I have a question here.

In linux, all the MIB files are stored under /usr/local/share/snmp/mibs folder.

The snmpd demon gets the mib files from there.

Similarly, Where exactly we have to put the mib files in uClinux? and how to tell the demon where these files are stored?

Best Regards,

Manu

Message: 52686    what you're asking is not related to Linux or uClinux.  that is a build time option given to configure.  the snmpd daemon wants is however you configured it.  as for how to configure/setup the snmpd daemon, you should review the snmpd man pages and/or included documentation.
