I am facing this particular error 

/usr/sbin/snmpd: symbol lookup error: /usr/sbin/snmpd: undefined symbol: smux_listen_sd

when I restart the snmpd service on my computer. Whenever I do the sudo service snmpd restart, it gives me the error shown above.

I have tried to search this issue on web, but the suggestion which I got is that snmp libraries are on present on path /usr/lib/ and /usr/local/lib/, but I could not see snmp libraries on both paths. My snmp libraries are present only on /usr/local/lib.

I also tried to uninstall snmpd, but it gave me same error. I don't want to remove net-snmp package as it has dependency on other modules. I am working on Ubuntu 13.10.

Could any one help me?

This is a relocation error.

One of the biggest advantages of package managers is that when you remove a package all that came with it gets removed. This does not happen with source installs.

Basically you should remove everything netsnmp related and then reinstall the package with apt:

  • remove net-snmp with apt-get. Use --nodeps if you don't want to remove the dependencies
  • locate all libsnmp versions you have in your system with find /usr/ -name libnetsnmp* and delete them.
  • alternatively, if you still have the source install folder on disk, you could try running sudo make uninstall in the same folder where you run sudo make install. This is cleaner but doesn't always work.
  • lastly install net-snmp with apt-get once again

You should be good to go

I found a answer step by step source:

I solve this problem

apt-get remove --purge snmpd cd /usr/local/lib/ rm libnetsnmp*

apt-get install snmpd

verify if this service is open netstat -anup

test this : snmpwalk -v 1 -c public localhost

Is good !!!
