I use SSHGuard on well ssh (doh!), but supposedly you can use it for postfix and dovecot also. I can tell you it is well supported. I am on Centos 7 using firewalld. ? Original Message ?

Hi, Sorry for the delay in replying. Been having a few mail problems ironically! Gmail smtp server stopped working!

Just to add another alternative while we're discussing the subject, I've got a soft spot for CSF as a replacement for fail2ban, and it has a lot of additional features as well. https://www.configserver.com/cp/csf.html P.

Hello, We had been seeing SIP-guessing attacks on our Asterisk server here. While it wasn't that hard to write a once-a-minute cron job to spank the lusers, that runs once a minute and creates little spikes in the usage and I/O graphs, and is slower to respond than I'd really prefer. I felt that it'd be much cooler to get something more comprehensive put together. We don't use

This is probably quite an easy question, but I haven't been able to find the answer. I'm running a server where all the email addresses are in the format "user at domain.com". I've noticed that a large number of fake login attempts use the format "user" eg. reception, service, root, admin. Is it possible to prevent any such logins to these email users without an

Is anyone using asterisk with fail2ban? I have it working except it takes way more break-in attempts than what is set in "maxretry" in jail.conf For example, I get an email saying: "The IP 199.204.45.19 has just been banned by Fail2Ban after 181 attempts against ASTERISK." when "maxretry = 5" in jail.conf Perhaps someone else is experiencing this or has resolved it,

Hello, is it possible to limit the number of pop3 (or imap) login attempts from one IP with dovecot to stop attackers? We recently had an attack from one IP-address lasting 50 minutes that tried 50000 pop3-logins with guessed users and passwords. I know about Fail2Ban but really would prefer an easy to configure solution inside of dovecot. Dovecot has this anvil daemon, can it be used

My amalgamated idea is:- (1) When external access gets a password wrong 'n' occasions, as determined by the SysAdmin, the external IP address is automatically permanently blocked

just wanted to get some feedback from the community. Over the last few days I have noticed my web server and email box have attempted to ssh'd to using weird names like admin,appuser,nobody,etc.... None of these are valid users. I know that I can block sshd all together with iptables but that will not work for us. I did a little research on google and found programs like sshguard and

Dear Members, I am working with 6-dimensional Student-t distribution with 4 degrees of freedom truncated to [20; 60]. I have generated 100 000 samples from truncated multivariate Student-t distribution using rtmvt function from package ?tmvtnorm?. I have also calculated mean vector using equation (3) from attached pdf. The problem is, that after summing all elements in one column of rtmvt result

Hello, I have a win32 DLL library, which I can't decompile, and can't get it's source code, but which I'd like to use in my Linux program. I wondered about making a win32<->Linux interface to use this library, using ready-to-use wine libraries. Is it possible, using wine libraries, to have access to functions from this DLL? If yes, can you tell me how? Thank you in
