Hi all, I wonder if there is a script to analyze logfiles for llogwatch and sshguard? Anyone knows? Adrian -- Adri P. van Bloois "Elegance is not a dispensable luxury but a factor that decides between success and failure." Edsger W. Dijkstra

Has anyone checked to make sure that this won't upset sshguard? [1] Offhand, it looks like it will [2][3].

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.

You can take an existing script, for another piece of software reported by Logwatch, retain the beginning and ending parts, and create your own version. The completed script should be placed in /etc to ensure it is not

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!

And most mail password attacks these days are distributed, and although

I have just deployed a new CentOS 6.4 image on AWS, and I'm having issues with init.d scripts not starting up. I've verified the following; 1) They work on their own after boot 2) They're set to run at runlevel 3,4, and 5 via chkconfig 3) The system boots up in runlevel 3 (no GUI) 4) There are no lingering PID files around after boot 5) Permissions

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

Good suggestion for sshguard. pjwelsh https://wiki.gentoo.org/wiki/Sshguard http://www.funtoo.org/Package:Sshguard There you go, I give permission to cross license & plagiarize my *ntoo content to centos's wiki. it should be very similar to a cent box except for yum install sshguard && chkconfig sshguard (or however that ones done) && service sshguard start -sixsixsix

Dear OpenSSH Developers, Thanks for all the great work on this important tool. We've built version 3.1p1 on SAPTC platforms under Solaris 2.8 using gcc 2.95.2. Several quick notes and a question: 1) There are several discrepancies between the INSTALL file on the openssh web site ftp://ftp.ca.openbsd.org/pub/OpenBSD/OpenSSH/portable/INSTALL and the output from "./configure

I am >on Centos 7 using firewalld. SSHGuard works fairly well with Postfix; however, it is virtually useless with Dovecot. It never picks up on "auth fail" and a few others. I have submitted

Hello, I use hosts that are dual stack configured (IPv4 and IPv6) and it happens that connectivity through one or the other is broken and timeouts. In these case connection to the SSH server can take quite some time as ssh waits for the first address to timeout before trying the next. So I gave a stab at implementing RFC 8305. This patch implements part of it in sshconnect.c. * It does not do

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

Hi there! I''ve using HTB for a while and now I an faced with a ''problem''. How hierarchical is HTB? Let''s say I have this 3 layer HTB setup: root class 1: (rate=100, ceil=100) 1: children classes 1:10 (30,100) and 1:20 (70,100) 1:10 children classes 1:100 (10,100) and 1:101 (20,100) 1:20 children classes 1:200 (30,100) and 1:201 (70,100) I managed to have

Ok, I see there's alot out there of voip providers. Curious what to watch out for ? charges and fee's, etc ? If anyone has feedback as to a GOOD voip provider experience (one that gave FREE DID) Please share.
