Updates / Re: The Future of CentOS Stream with CWP
« on: October 22, 2024, 10:24:21 AM »
Hi,
This post is correct and outdated at the same time because it was created on "December 13, 2020". Currently, the recommended distro for CWP is Almalinux 8.

If you disabled CSF/Firewall, dig, nslookup show correct answers but you can't connect to the port 25 of another VM then there is some networking problem. It could be your router or some other device used to manage traffic. I am afraid the CWP community is unable to help you with it because it requires deeper understanding of your infrastructure and network configuration.

1. Did you disable CSF/Firewall on both VMs ? Does it try to access the VM2 from VM1 using public or private IP ?
2. What did the test 2 show exactly when it failed ?
3. does "nslookup MX.DOMAIN.COM" (replace MX.DOMAIN.COM with the actual MX record of the domain hosted on VM2) executed on VM1 shows the same result as "dig" ?

Disable CSF/IPtables and run tests 2,3 again. If the tests are passed with the disabled CSF/iptables then check your CSF/iptables rules.

Remove any extra lines from /etc/hosts added by you:
1. On VM1 can you resolve the MX records of the domain hosted on VM2 ?
2. Can you connect to the port 25 from VM1 to the host/IP resolved in p1 ?
3. Does the traceroute command executed on VM1 to the host/ip resolved in p1 look good (VM2 is accessible) ?

Dude, just forget about outgoing emails to yahoo, gmail, etc because they have correcet MX records and can be resolved from any correctly configured and working host.
Your VMs are behind NAT. So:
1. Check the MX records of your domains, make sure they are correct and working.
2. Check resolvers on your VMs. The resolvers can resolve the IP address of the MX records.
3. Check if routing from one VM to MX record of the domain hosted on another VM is ok.

I don't see anything. Your VPS operated and then boot process was initiated. It looks like someone pressed "Reset":

1. Log into SSH of your server as root
2. Open less, vi, nano or another editor:
In case there is nothing then check processes running on your server/vps when you run the php compilation process.

E-Mail / Re: how to block user ip if tried x attempts login failed in Roundcube
« on: October 16, 2024, 07:58:12 PM »
Excellent! However, I recommend to use the second variant of "return()":
because Roundcube/webmail can be accessed in different ways. Therefore the ports 80,443,2095,2096 must be blocked for the abuser.
Code: [Select]
return ("Failed Roundcube login attempt from IP: $1",$1,"roundcubelogin","5","80,443,2095,2096","300","0");because Roundcube/webmail can be accessed in different ways. Therefore the ports 80,443,2095,2096 must be blocked for the abuser.

If the above "return()" doesn't work then change it to:
and test again (we block the ports 80,443,2095,2096 for the abuser).
Code: [Select]
return ("Failed Roundcube login attempt from IP: $1",$1,"roundcubelogin","5","80,443,2095,2096","300","0");and test again (we block the ports 80,443,2095,2096 for the abuser).

I think to catch the IP address you can use the following regexp:
and the function return should look like:
Additionally, I think you need to pay attention to "CUSTOM1_LOG", set it to the correct CUSTOMX_LOG.
Code: [Select]
$line =~ /Failed login.*X-Real-IP:\s(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}),X-Forwarded-For/and the function return should look like:
Code: [Select]
return ("Failed Roundcube login attempt from IP: $1",$1,"roundcubelogin","5","2095,2096","300","0");Additionally, I think you need to pay attention to "CUSTOM1_LOG", set it to the correct CUSTOMX_LOG.
