f31195a4fc added new logtarget "SYSOUT" to log from fail2ban working in foreground as systemd-service (in opposite to "STDOUT" don't log time-stamps). 2017-11-26 23:03:29 +01:00

159957ab88 filter.d/sshd.conf: extended failregex for modes "extra"/"aggressive": now finds all possible (also future) forms of "no matching (cipher|mac|MAC|compression method|key exchange method|host key type) found", see "ssherr.c" for all possible SSH_ERR_..._ALG_MATCH errors; 
obsolete (multi-line buffered) variant extended also.

Closes gh-1943, gh-1944

eba68a8f37 config/paths-common.conf: Added initial values for syslog_authpriv, syslog_mail in order to avoid errors while parsing/interpolating configuration; 
Note the systemd-backend does not need the logpath at all;
Some defaults normalized (minimized configs, don't need to overwrite values in distribution-related path if equal).

9876dd44f9 replace port imap3 with imap everywhere, since imap3 is not a standard port and old rarely (if ever) used and missing on some systems 
(see gh-1942)

4a2fc8b7e8 Include imap (port 143) in courier-auth ports 
imap was missing from the list of ports, preventing fail2ban from blocking connections on standard IMAP port 143.

b615a98540 jail.conf: avoid overwriting of default value of the parameter chain of several actions (where default chain != INPUT); 
test-cases extended to cover the same logic (use `<known/chain>` instead of fix value `INPUT`);

8726c9fb0a pf.conf: enclose ports in braces, multiple ports expecting this syntax ... any port {http, https}.

Fix comment, because current one won't work:

cat /etc/pf.conf
anchor f2b {
  sshd
}

# service pf reload
Reloading pf rules.
/etc/pf.conf:2: syntax error

New version:

cat /etc/pf.conf
anchor f2b {
  anchor sshd
}

# service pf reload
Reloading pf rules.

Fix nftables actions for IPv6 addresses, fixes #1893 
* add [Init?family=inet6] to nftables-common.conf and make nftable
  expressions more modular
* change "ip protocol" to "meta l4proto" in nftables-allports.conf

9b8563f35e - fixes regex for message imap-login: Disconnected (auth failed, X attempts) ... has to many variations on additional info after <HOST>, 
leave it end-anchored because variable part `user=<[^>]*>` (before `<HOST>`) to avoid injecting, but can be safe rewritten using `[^>]*` in opposite to "greedy" `user=<[^>]*>`.
- introduces mode `aggressive` and extends regex for this mode to match:
  * no auth attempts (previously removed in gh-601, because of lots of false positives on misconfigured MTAs)
  * disconnected before auth was ready
  * client didn't finish SASL auth
