Configuration Pains with Postfix

In the start of 2018 around February I finally got everything in place to send and receive emails. For now my server just sends emails not receive. I want to investigate more into the authorization system for postfix and currently at the moment I caught up on ways to create listeners which I need for another project. I want to create an aspnet core version of squirrel mail but for now things are where I need them. https://linux-audit.com/postfix-hardening-guide-for-security-and-privacy/#test-the-existing-postfix-configuration https://linux-audit.com/postfix-hardening-guide-for-security-and-privacy/#test-the-existing-postfix-configuration https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-postfix-as-a-send-only-smtp-server-on-ubuntu-14-04 http://postfix.state-of-mind.de/patrick.koetter/smtpauth/smtp_auth_mailclients.html https://serverfault.com/questions/712903/503-5-5-1-error-authentication-not-enabled-when-trying-to-connect-to-my-postf https://github.com/nl...

Mongodb Cheatsheet

This cheat sheet is based on the latest version of mongodb, which initial had setup and didn't encounter any problems. However that all changed when I was working remote and forgot I disabled the port no my network, rather than with the server. So I went pointing around where I didn't need to and ended up messing things up. The Best tutorial out there is of course on digital ocean for my setup on ubuntu 16.04 , this articles isn't so much about getting setup. I just wanted to include it because I found myself looking back at it to see if I missed a step. Bugs/Problems Now comes all the messed up things I found and had to deal with. firewall - Port seems to be open, but connection refused try using 0.0.0.0 in the bin_ip for the /etc/mongo.conf try sudo ufw disable and check to see if it works without the firewall (probably still wont but worth a shot), then just sudo ufw enable.

Sadly they don't have parameters in the url so I can link the machine I used in this article. -  https://coolstar.org/chromebook/windows-install.html Scared of messing with the bios? Don't be!    So you need to first remove the screw to put a legacy bios on the machine. Its easy to backup the chrome os one and with the same steps to change it. You can go back in and revert to the chrome version bios. Its that last part that had me worried and its very easy to do.  Problems getting into Developer Mode?   Follow the instructions to the letter, during the step to disable the OS verification, press Ctrl-D to boot into os. If you hear two beeps I would go back to set one. I got in a loo...
