The do it yourself way!
OpenVPN is one of the open source applications that allows you to create your own Virtual Private Network. We are not going to cover all the topics regarding VPNs, but for short these are used to transfer data from point A to point B in a secure way. Of course this allows us to bypass …
Before providing the solution let me first describe you the issue.
Early this morning I received a request from a customer to check out his servers he suspected that these were hacked. He complained about a similar issues a couple of weeks ago when he suspected something was wrong with nginx, apparently visitors from US were redirected to a page containing malware.
[root@server ~]# yum -y install subversion
sudo yum install subversion
sudo /usr/sbin/useradd svn
sudo passwd svn
su – svn
cd ~
mkdir repositories
cd repositories
svnadmin create myproject
ll myproject
-rw-rw-r– 1 svn svn 229 Nov 21 16:58 README.txt
drwxrwxr-x 2 svn svn 1024 Nov 21 16:58 conf

You need to edit “myproject/conf/svnserve.conf” and uncomment the following lines:
auth-access = write
password-db = passwd
and edit the password file “myproject/conf/passwd” adding a new user and password. Note that the password is stored in plain text. In the following example we have a user called “john” whose password is “foobar123”:
[users]
john = foobar123
And finally, as the svn user, start the subversion daemon like so:
svnserve -d -r /home/svn/repositories
Connect to svn://svn@hostname/myproject
After updating mysql on a server that is running cpanel, Nagios kept reporting that mysql is down. I double checked and the database server was running just fine, so I proceeded with a step by step analysis, the issue proved to be the following:
root@cpanel [~]# /usr/local/nagios/libexec/check_mysql /usr/local/nagios/libexec/check_mysql: error while loading shared libraries: libmysqlclient.so.15: cannot open shared object file: No such file or directory
