Hi All, On two occasions now since I set up my server I have checked the log messages and each time rkhunter warns about this hidden file. #Warning: Hidden File Found: /sbin/.cryptsetup.hmac: ASCII text Just wondering what it is. I have run rkhunter --propupd But the warning still persists. Also there is a warning about SSH and rkhunter. The SSH and rkhunter configuration options should be the same. SSH configuration 'Protocol:2' Rkhunter configuration option 'ALLOW_SSH_PROT_V1':2 Which config should be tweaked to match. Thanks in advance. Any pointers will be appreciated.
