the log file auth.log has dissappeared on my ubuntu 14.04 server. Fail2ban log says that suddenly the file was gone:
2016-04-16 21:59:56,735 fail2ban.actions: WARNING [ssh] Ban 192.169.189.36
2016-04-17 01:27:51,182 fail2ban.filter : ERROR Unable to get stat on /var/log/auth.log because of: [Errno 2] No such file or directory: '/var/log/auth.log'
2016-04-17 01:27:51,185 fail2ban.filter : ERROR Unable to get stat on /var/log/auth.log because of: [Errno 2] No such file or directory: '/var/log/auth.log'
and fail2ban service finally went idle.
How can I recreate auth.log and mail.log and even more important does anybody have an idea how this could have happened? Thanks in advance for any tips.
