HOWTO: Small Mail Server With Salt, Dovecot, And OpenSMTPD

2015-01-26 by Mohammad H. Al-Shami

Update: Sadly OpenSMTPD version 5.4.4 on FreeBSD broke the passwd table, I’m checking the Gills to get this fixed.

Update2: I am no longer using OpenSMTPD. I’ve switched to dma for servers that only need to send emails and went back to Postfix for servers that require an actual MTA. Not that OpenSMTPD is bad, I just prefer Postfix. I might reconcider in the future when OpenSMTPD is more mature.

Perl One-liner To Generate htpasswd Passwords

2014-12-29 by Mohammad H. Al-Shami

Update: An easier way to do it that doesn’t require you to install anything special (Works with nginx)

openssl passwd -apr1

Instead of having to install Apache or use an untrusted website just to generate the required password, you can use the following perl one liner

perl -e 'chomp($password=<>);chomp($salt=`tr -dc A-Za-z0-9 </dev/urandom | head -c 1024`); print crypt($password,$salt)."\n";'

Update: I have since moved to Damamax and am MUCH happier with their service. Their network is more reliable, faster, and their support staff is wonderful. It’s a bit more expensive but considering the advantages I highly recommend switching if they cover your area.

Simulating Cron Runs On The Command Line

2014-10-15 by Mohammad H. Al-Shami

Does this sound familiar?

You write a new script, start it from the command line, everything works properly, you add that script to your crontab then go home, the next day, nothing. So you end up setting up a schedule to run this script the next minute, the script fails, you change something, update the schedule, rinse and repeat.

ADSL In Jordan

2011-08-03 by Mohammad H. Al-Shami

I’ve heard various complaints from a few friends of mine about the status of Internet connectivity in Jordan, especially ADSL. So I’m writing this article to explain what is going on and why ADSL the way it is, but first, some history.

Back in pre-broadband times, people used dial-up modems to connect to the Internet. The name “modem” came from the fact that data was being modulated (Turned from digital to analog form) to be sent over the phone lines, and demodulated (Turned from analog to digital form) at the other end. This utilized the same frequencies used for regular phone conversations, this is why you could hear the weird sounds if you picked the phone up while being connected to the Internet. Given the relatively narrow frequency range used by phones this technology was limited to about 56Kbps, the best speed I got was back in 2003 which was about 5KB/s for my downloads, and that was considered fast at the time.
