[Sshguard-maintainers] recommendations

[Mij <mi...@bi...>]

Some up to date recommendations when packaging sshguard:

- always use sshguard v. 0.91
- when a URL to the project is to be included, use 
http://sshguard.sourceforge.net
- make sshguard run in syslog / syslog-ng whenever possible
- if you run sshguard standalone, use "tail -n -F src_logfile" (not -f 
as pointed in README),
and determine the correct src_logfile that gets ssh entries in the 
target system
- if you run sshguard with syslog-ng, mind to use the following filter:

filter sshlogs { facility(auth, authpriv) and match("ssh"); };

(add "auth, " to the filter reported in README)
- LINUX: sshguard wants iptables in /sbin/ by default. If the target 
system has iptables somewhere
else, mind to adjust paths in file fwalls/command_iptables.h before 
configuring
