Before last night I had been experiencing problems getting NetSNMP's mib2c software to launch. I searched the web and newsgroups with google, and even though the question has been posted many times, I didn't find a good solution to the problem at first.
Since I did eventually figure it out however, I thought I'd post to this mailing list to help out others who may experience this problem in the future!
The Problem: When running mib2c, you get the following error:
/usr/lib/libnetsnmp.so.5: undefined symbol: RAND_bytes
Before the solution, let us discuss what this error means!
The error is basically the dynamic linker telling you that the shared object libnetsnmp.so
is referencing a function named RAND_bytes, that cannot be found. RAND_bytes belongs to the OpenSSL package. So first off, make sure you have the OpenSSL package. There is a 99% chance you already have the package, but NetSNMP just can't find it.
So the solution is to:
1) Make sure you have OpenSSL
2) Tell NetSNMP the location of OpenSSL through NetSNMPs configuration script.
3) Also, Tell NetSNMP to include perl modules. Mib2c won't run without them.
Assuming OpenSSL is installed on your system, you can do the above with the following in the NetSNMP Distribution source directory.
./configure --with-openssl=/usr/lib --with-perl-modules
Replace
/usr/lib/ with whatever folder contains the libssl.so shared object
library files. Then run make, make install, and all should be right in
the world again!
You may also want to run "make test" to make sure everythign else is alright, in case you have other problems that I did not.
I hope this helps others in the future. Cheers!
