Super Mario RPG is out early on all the rom sites! Ive been playing it on steam deck and it runs pretty well with ryujinx. On yuzu it freezes at the start with a black screen. This was my very first RPG as a child and I was obsessed with this game. I even had a geocities website for it! Anyone else pumped for this remake??

Use Fail2ban and Postscreen to Fight Botnet Connections to Postfix


I noticed multiple unsuccessful connection attempts in my postfix server from various IPs. The EHLO response varies but many of them respond as "User\r\n". See the following log entries from my /var/log/postfix.log file...
Nov 10 19:20:58 mail postfix/postscreen[18652]: COMMAND PIPELINING from [162.142.125.10]:57044 after ??????: 6\2
Nov 10 19:20:57 mail postfix/postscreen[18652]: COMMAND PIPELINING from [162.142.125.10]:46298 after ??????: W\
Nov 6 05:57:36 mail postfix/postscreen[15159]: PREGREET 11 after 0.12 from [147.78.103.88]:56690: EHLO User\r\n
Oct 30 04:05:40 mail postfix/postscreen[8417]: PREGREET 11 after 0.13 from [87.120.84.90]:58426: EHLO User\r\n
Oct 30 04:54:26 mail postfix/postscreen[9258]: PREGREET 11 after 0.13 from [87.120.84.90]:51143: EHLO User\r\n
Oct 30 06:50:04 mail postfix/postscreen[11318]: PREGREET 11 after 0.13 from [147.78.103.88]:52788: EHLO User\r\n
Oct 30 05:37:00 mail postfix/postscreen[9963]: PREGREET 11 after 0.13 from [147.78.103.88]:54640: EHLO User\r\n

As you can see, these connection attempts are coming from many different IP addresses. The best way to handle these attempts is with a custom Fail2ban rule that can match against the EHLO response. Fail2ban is log monitoring software that is able to take action when it matches a rule. These actions can vary but the default is to "ban" the IP and/or port by creating a rule in iptables. I will walk through the setup of this custom Fail2ban rule and the subsequent testing and verifying of the rule.

Send Email in your PowerShell Script - The Modern Method


With modern companies using hosted email solutions, Microsoft has deprecated the use of the Send-MailMessage PowerShell cmdlet. The supported to way to send emails from a PowerShell script is with the Microsoft Graph API. Unfortunately, this is not as simple as using an on-premises SMTP server, but it's much more secure. And by building a proper PowerShell function, it's just as easy to integrate within your scripts. This does require an Office365 tenant and subscription. I will outline the steps and give an example of how to send emails with this method.
