OS that I am using: Fedora 15.
Today morning, I removed net-snmp rpm package previously installed on my system. Then, I compiled and installed snmp from source. Compiled snmpd does not respond to any get requests.
I installed the package by executing these commands:
./.configure && make && make install
After a while it was done and I find the installation was successful.
For testing the installation I ran a get request:
snmpget -v2c -c public 127.0.0.1 sysDescr.0
Weird I feel, no response... What could I be missing? a super-user privilege is required?
Additionally, there are few steps that need to be performed for installation from source.
Follow here,
Step 1: Log in as root (su - root)
Step 2: Navigate to the home folder where the net-snmp tar.gz is kept Issue this command at the prompt
tar -zxvf net-snmp-5.5.tar.gz
(I still happen to use v 5.5. Change this with your version)
Step 3: Navigate to the un-tarred directory.
Step 4: Run ./configure
Step 5: make
Step 6: make install
Step 7: You now have netsnmp installed and ready to use.
Ha Ha .. not quite.. there are still lot of stuff that needs to be done before we can say...yep..thats working beautifully..
Step 8: Navigate to /usr/local/bin to see if the folder has a bunch of snmp stuff like snmpconf snmptranslate and so on...
Step 9: Also see if the /usr/local/share/snmp/mibs folder and see if all the MIB files are present..
Step 10: If everything is fine until here try to do some configurations checking (else start-over). Run,
net-snmp-config --default-mibdirs
and you must get the output
/root/.snmp/mibs:/usr/local/share/snmp/mibs
Run,
net-snmp-config --snmpconfpath
output should be like
/usr/local/etc/snmp:/usr/local/share/snmp:/usr/local/lib/snmp:/root/.snmp:/var/net-snmp
Step 11: Run,
ldd /usr/local/bin/snmptranslate
output will be:
linux-gate.so.1 => (0x00110000)
libnetsnmpagent.so.15 => not found
libnetsnmphelpers.so.15 => not found
libnetsnmpmibs.so.15 => not found
libnetsnmp.so.15 => not found
This means that you might get snmp*: error while loading shared libraries: like for example as mentioned above libnetsnmp.so.20: It cannot open shared object file.
If no error comes like above , no need to do anything, but if error comes, then, you have to do the steps below Edit ld.so.conf in /etc and add the details of the lib path of /usr/local/lib and then run ldconfig
vi /etc/ld.so.conf
/usr/X11R6/lib/Xaw3d
/usr/X11R6/lib
/usr/lib/Xaw3d
/usr/i386-suse-linux/lib
/usr/local/lib
/opt/kde3/lib
include /etc/ld.so.conf.d/*.conf
(I happen to Use Suse a lot. But something is also very similar to Debian)
Step 12: Run,
ldconfig
Step 13: Now you have to tell netsnmp where to look for MIB files. You use the snmpconf command to do this. Issue this command at the prompt.
snmpconf
This is what it will appear on your screen,
I can create the following types of configuration files for you. Select the file type you wish to create: (you can create more than one as you run this program) 1: snmpd.conf 2: snmptrapd.conf 3: snmp.conf Other options: quit
Select File: 3
The configuration information which can be put into snmp.conf is divided into sections. Select a configuration section for snmp.conf that you wish to create: 1: Debugging output options 2: Textual mib parsing 3: Output style options 4: Default Authentication Options Other options: finished
Select section: finished
I can create the following types of configuration files for you. Select the file type you wish to create: (you can create more than one as you run this program) 1: snmpd.conf 2: snmptrapd.conf 3: snmp.conf Other options: quit
Select File: quit
The following files were created: snmp.conf
These files should be moved to /usr/local/share/snmp if you want them used by everyone on the system. In the future, if you add the -i option to the command line I'll copy them there automatically for you.
Or, if you want them for your personal use only, copy them to /root/.snmp . In the future, if you add the -p option to the command line I'll copy them there automatically for you.
Step 14: Copy the snmp.conf file.
cp snmp.conf /usr/local/share/snmp/
Step 15: Finally try this.
snmptranslate -Tp -IR ipMIB
You will observe a tree structure on your screen. This means that everything that you have installed is working
So now the errors are not going to be there because of configuration.. whatever gets screwed up , its your responsibilty ;-)
Cheers,
