Installation: FAQ

Chown errors during installation on AIX:

AIX does not accept /bin/false as a valid shell by default. It must be added to the SHELLS line in /etc/security/login.cfg before running install.sh.

The Windows GUI is asking me for a key, where do I get it?

The Windows version of OSSEC is agent only, it cannot work without a server. The key can be obtained from the server using manage_agents.

How do I verify the release tarball GPG signature?

Tarballs from https://www.ossec.net/download-ossec/ and GitHub Releases ship with a detached .asc signature file. Import the public key published at https://www.ossec.net/files/OSSEC-ARCHIVE-KEY.asc, then run gpg --verify on the tarball before installing.

Full step-by-step commands are in Manager/Agent Installation under “Verify the tarball signature”.
