Hi everybody, I manage an Ispconfig Debian Wheezy server, and lately I'm getting this error from the rkhunter daily report: Code: Error: Invalid display - keyword cannot be found: Display line: display --to LOG --type INFO NETWORK_PORTS_DISABLE_PATHS don't know if it's related, but rkhunter -C says: Code: Command cannot be found: MAIL_CMD=mail -s "[rkhunter] Warnings found for ${HOST_NAME}" I tried rkhunter --propud already, without results. I can't find any reference to this error on the Internet, so I don't know where I should look to solve this issue, or at least to understand what's about.
