I tried to install an OpenVPN access server in Centos 6 on a linode VPS.
The installation is okay for my ubuntu 11.10 distro in another VPS. The installation error occours when adding the user "openvpn" in Centos.
The error message is
"useradd: canot open /etc/passwd"
The detail of My "/etc/passwd" file:
"-rw-r--r-- 1 root root 1194 Oct 9 00:33 /etc/passwd"
I am not quite familiar with Centos, so how can I add the user "openvpn" in order to setup the VPN service?
