snmpd not starting
Good Afternoon,
I've been struggling with a snmp issue on a CentOS 4.8 machine for several days. I've installed snmp (yum install net-snmp), but it refuses to start. Running "service snmpd start" appears to have started the process, but running service snmpd status" results in "snmpd dead but subsys locked". Looking in /var/log/messages only has the "snmp started" entry.
I've spent a lot of time on Google and one of the things I have tried is running "snmpd -f -Le. This results in "snmpd: symbol lookup error: /usr/lib/libnetsnmp.so.5: undefined symbol: RAND_bytes".
I've tried uninstalling and reinstalling snmp, but no luck. I've also removed the resulting /var/lock and /var/run files.
Any help on this would be greatly appreciated.
Thank you,
Lewis

Arnold,
The libs get installed with net-snmp. I've installed the utils and also the devel. Same results.

I have not used 4 in a while, and not sure what the issue is when you start it.
What is the output in /var/log/messages when you start it with the default options?
Do you have /etc/snmp/snmpd.conf file?
Do you have iptables running and if so did you setup a rule to allow UDP port 161 to pass?

Arnold,
The only entry in /var/log/messages is that snmp was started. For testing, just using the snmpd.conf file that is created when installing snmp. No iptables.

Seems that you're missing OpenSSL!

OpenSSL is installed. Running "yum search openssl |grep ssl" shows the following.

Well,
it could be that OpenSSL is searched in the wrong place by snmpd
What do you get with
ldd /usr/sbin/snmpd
(particularly lokk for libcrypto - is it where snmpd expects it to be)?

That's just strange. What gives
ldd -r /usr/sbin/snmpd ?
Also, you could run ldconfig to rebuild the cache and links.
And, do you find RAND_bytes with
strings /usr/lib/libcrypto.so.4 | grep RAND ?

I thought of that, but there are so many dependancies on openssl (438). If I do a yum remove open ssl is comes back and asks if it's ok to remove 428 packages.
Am I doing it right?
Am I doing it right?
Well, you're far more familiar with yum than I am.
Isn't there a possibility to do a forced reinstall of the current version, without deinstalling beforehand?
I didn't find such a thing in yum, but as I said, I don't use it ...
But please, don't remove dependent sotware. If you must deinstall, try to find a way to leave other installed software intact!

He nailed it that it was SSL. The problem was that you can't really uninstall ssl without nuking the system. We ended up re-installing from scratch.
run rpm -qa | grep -i snmp
do you have net-snmp-libs net-snmp-utils installed?
