Find a way to block brute force attacks.
Hello list. I'm trying to find a way to block any ip that tries to login more than three times with the wrong password and try to log in three different extensions. For I have suffered some brute force attacks on my asterisk in the morning period. The idea would be: Any ip with three attempts without success to log into an extension is blocked. Is there any way to accomplish this directly

HTB
Hello, I have problems with htb. The problem is that when I download any file via shaper with htb, the traffic is very dinamic, it jumps, for example: if i have set ceil = 128kbit the results that it jumps from 112kbps to 144kbps or smth like that maybe its not very bad, but when the traffic drops down to 40kbps or less and then after 1 or 2 seconds jumps to 144kbps, its bad :-( and it is often.

DCC rule set
I have been given a set of "firewall rules" to open my firewall for DCC to support my spam filtering. (I have done many web searches trying to find info relating to DCC with Shorewall, to no avail.

list all emails from command line?
This is not strictly Dovecot question, but a more general IMAP one. I'm running a Dovecot server and have a user who is claiming that some email sent to him, say, on 30 May, showed up in his mailbox on 02 Jun. I've checked Postfix logs, and the message was correctly received on 30 May and passed to Dovecot. A similar issue happens every few days. This leaves me with two possibilities:

SSH scans vs connection ratelimiting
Gang, For months now, we're all seeing repeated bruteforce attempts on SSH. I've configured my pf install to ratelimit TCP connections to port 22 and to automatically add IP-addresses that connect too fast to a table that's filtered: table <lamers> { } block quick from <lamers> to any pass in quick on $ext_if inet proto tcp from any to ($ext_if) port 22 modulate

Quota plugin and SQL
I have read through http://wiki.dovecot.org/Quota/Dict, which suggests a database schema for using quota. For 1.2, this includes a username, bytes and messages. Is there any way to modify the queries used to split out username into localpart and domain? This would enable me to put the current quota information in my main mailbox table and display it to users in my admin interface. Or
