    I've been checking the COS5.2 fail2ban jail.local and jail.conf and log locations where in the jail.* files. Since COS7 is using systemd with logs, is where the problem is???
    In the new jail.conf it shows
    I can't figure out what it is referencing.
    When I query what log postfix is using for fail2ban it says
    I guess this is correct since it isn't starting so not reading any logs. This is going beyond my novice knowledge.
    Could this be an issue if both postfix-sasl and cyrus jails are reading the same log at the same time?

    I kept my options open when creating the initial certificate with certbot before the Let's Encrypt app was released. With the Let's Encrypt App, it can only cover one FQDN. I believe that from 27th February, Let's Encrypt will release a wildcard certificate which makes life easier but I have no idea if you can request one with the app.

    Nick, I don't think I understand what you mean.
    When I did the original install I created 1 certificate for my home domain and also one virtual domain within the same certificate as you have. So with the MarketPlace App you can't do this? Since i need it to cover 2 domains, I should stay with my present manual installation and not change to the Marketplace App?
    Thanks again for your help!

    HI Nuke,
    Can you disable all jails in the webconfig then start them one by one? By your logs it looks like sshd-ddos and postfix-sasl are failing. I use postfix-sasl but no sshd jails as I don't open ssh to the internet. My postfix-sasl is slightly altered from base so I wonder if that is why mine works.

    Hi Nick.
    Thanks again for your help.
    I disabled all jails except for cyrus-imapd and fail2ban started OK.
    I don't have port 22 open to the outside either. I presume I don't have to worry about this sshd-ddos running if the port is closed?
    I'd like to get postfix-sasl running as I'm running a home mail server.
    There looks to be some sort of clear files in addition to the jail.conf to control fail2ban. If I make changes in a jail.local am going to break something with COS7?
    It's been years since I adjusted/tuned fail2ban on COS5.2.

    Just wanted to let everyone know that moving to 1.10.1.4602 also seems to have gone smoothly.

    I also revised the process a little:

    Attack Detector/fail2ban stopped??

    Hi.
    Last week after doing the firmware updates for Spectre & Meltdown and rebooting, fail2ban will not run. It starts and then quits after showing this error "NOTICE Jail started without 'journalmatch' set". I've tried to restart/condrestart using systemctl and the webgui. The restart using the webgui hangs the webgui. The systemctl commands restart & condrestart seem to work but when I use systemctl start fail2ban or fail2ban.service, the CLI never completes the command.



    The log doesn't give much more info.


    I haven't changed anything on fail2ban. All I've done over the past week is to try to restart it when I noticed it wasn't running.

    What should I be looking at to get this running?

    Nuke replied to a discussion, Forward one user email to gmail?

    I had all sorts of problems with email since I did the forwarding. I'm not quite sure what the problem was but suspect that this forwarding was the problem or a part of it.

    Ben I tried your suggestions and I liked the fact that I could add forwards from the GUI.

    However it looked like all outbound mail was not leaving. I followed up with a number of people who I sent emails to but they never received anything. So for about 3 days we didn't send any emails. The logs show the email going to mailfilter and then being deleted.

    As I said, there may have been other factors in play because I fixed a certificate issue and imapd failure at the same time as removing the /var/clearos/mail_routing/forwarders file. Upon deleting the forwarders file, doing the aliases command and then reloading postfix, it looks like it's working properly again.

    I think this forwarders file solution needs some more testing.

    I don't know about your last error. Are you connecting to cyrus-imap using STARTTLS (SSL/TLS) or SSL?

    I believe the options in Thunderbird & K-9 are STARTTLS or SSL/TLS. I have SSL/TLS enabled for imaps and pops email. Regular imap and pop are disabled.
