Package: fail2ban
Version: 0.8.3-2sid1
Severity: important
Tags: patch
Fail2ban fails detecting potential attacks to the proftpd daemon, due to a
syntax error in the filter /etc/fail2ban/filter.d.
To fix this problem you just need to edit /etc/fail2ban/filter.d and change it
as follows:
failregex = \(\S+\[<HOST>\]\)[: -]+ USER \S+: no such user found from \S+
\[\S+\] to \S+:\S+$
\(\S+\[<HOST>\]\)[: -]+ USER \S+ \(Login failed\): Incorrect
password\.$
\(\S+\[<HOST>\]\)[: -]+ SECURITY VIOLATION: \S+ login attempted\.$
\(\S+\[<HOST>\]\)[: -]+ Maximum login attempts \(\d+\) exceeded$
becomes:
failregex = \(\S+\[<HOST>\]\)[: ]+ USER \S+: no such user found from \S+
\[\S+\] to \S+:\S+$
\(\S+\[<HOST>\]\)[: ]+ USER \S+ \(Login failed\): Incorrect
password\.$
\(\S+\[<HOST>\]\)[: ]+ SECURITY VIOLATION: \S+ login attempted\.$
\(\S+\[<HOST>\]\)[: ]+ Maximum login attempts \(\d+\) exceeded$
After doing that, just restart Fail2ban daemon:
# /etc/init.d/fail2ban restart
Bye,
Ivan Agliardi
