Upon entering the command Rkhunter --update in my Kali Linux distribution. The result is as follows

[ Rootkit Hunter version 1.4.6 ]

Doing the update it always skips checking some files. Is this behaviour normal for Rkhunter or some configuration problem has occurred?

My distro is Kali Linux 4.15.0-kali3-amd64

  • What are the relevant contents of /var/log/rkhunter.log? – Jeff Schaller May 28 '18 at 22:57

The i18n/* files are just for localization purposes, so they are not essential for core program functionality. The output you've posted suggests you already have the English strings.

Side note #1: You shouldn't be running rkhunter --update as it is a security risk: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=765895 Install rkhunter via apt and let your package manager take care of keeping the utility updated.

Side note #2: rkhunter can generate a lot of false positives, so be prepared for that.

  • Thank you very much and yes due to the false positives I switched to Lynis – Aaryan BHAGAT May 29 '18 at 12:41
