With OpenSUSE, things are very easy. Select your favorite package manager (I tend to use which ever one comes up first!) and install the RPM for opie – under the group Productivity/Security.
Install the RPM, and all of the opie tools are available. Using opie to control your one-time passwords (OTP) has been discussed before, and nothing changes under OpenSUSE. However, installing OTP into PAM requires changing a different file (/etc/pam.d/common-auth). Add to the end of this file the following:
auth sufficient pam_opie.so use_first_pass
This should be enough to allow the use of OTP in most normal situations. The other directions are as they were presented in a previous blog post. Namely: use
opiepasswd to create the initial key and password, and use
opiekey to generate a list of upcoming OTP keys if desired.
