libssl error using CentOS6

[globalive.nagios]

I was getting this on a specific host, took me a bit to track down, so figured I'd post here.

Code: Select all

[root@mysql-02 plugins]# ./check_tcp -p 22
./check_tcp: error while loading shared libraries: libssl.so.6: cannot open shared object file: No such file or directory

It was working fine on another host with pretty much the exact same config, so very puzzling. I figured a package was missing:

Code: Select all

yum list installed | grep ssl

Working host returned:

Code: Select all

[root@mysql-01 plugins]# yum list installed | grep ssl
openssl.x86_64         1.0.0-4.el6_0.2  @updates                                
openssl098e.x86_64     0.9.8e-17.el6.centos

Non-working host returned:

Code: Select all

[root@mysql-02 plugins]# yum list installed | grep ssl
openssl.x86_64        1.0.0-4.el6_0.2   @updates

Installed the openssl098e.x86_64 package via yum, and all working now!
