Slicehost DataCenter migration for St. Louis (STL) to Chicago (ORD)

Tonight I’m migration ProgClub and Blackbrick’s Slicehost slices from the St. Louis DataCenter to the Chicago DataCenter. I had to do a little prep work on charity, hope and honesty. Since that’s been done I’ve kicked off the migrations in the web-based Slice Manager, and at the moment I’m waiting for the migration operations to happen as they’re presently queued. There was some articles from Slicehost about the migration process which I read: Migration to Rackspace Cloud: [Sticky] St. Louis (STL) to Chicago (ORD) Migration Instructions and STL to ORD Migration Best Practices.

RIP Daniel Beck

A few months ago I learned of my friend’s death. I don’t know much except that he killed himself a while ago now. I only found out about it a long time after it had happened, so didn’t get the chance to go to a funeral or anything like that. I’m not even sure of when exactly it did happen.

Daniel Beck was a friend of mine from high school. In 1999 when we were both in Year 12 at Blaxland Highschool together we ventured into our first “tech startup” together: Elliot-Beck Computer Solutions. That was really when I started out in the tech industry for the first time.

Our company never really went anywhere, and I’ve been involved in a number of such collusions over the years that didn’t really go anywhere either. But the first one was with La Becky, and I’m so sad that he’s gone, and worse that I’d fallen out of touch and wasn’t there when he needed me.

To all my friends: please never ever kill yourself. I’ve lost too many friends to suicide. Always call me and let me talk you out of it. It’s not possible to call me too late at night, you call any time (my contact details are kept up-to-date on jj5.net). I don’t care how many years have passed since we’ve spoken. I’ll come and see you. I’ll send money. I’ll help you destroy the evidence. Whatever it takes.

Tonight I found some of the old artwork for the Elliot-Beck Computer Solutions web-site and some photos we took in April 1999 while we were putting our web-site together. I will leave you with it.















































































Postfix smtps configuration

I found some information on configuring Postfix to provide SMTPS (SSL/TLS) services on CentOS 5.1 Server Setup: LAMP, Email, DNS, FTP, ISPConfig (a.k.a. The Perfect Server) – Page 5 and Getting Postfix to run SMTPS on port 465.

The first article suggests main.cf configuration settings such as:

postconf -e 'smtpd_sasl_local_domain ='
postconf -e 'smtpd_sasl_auth_enable = yes'
postconf -e 'smtpd_sasl_security_options = noanonymous'
postconf -e 'broken_sasl_auth_clients = yes'
postconf -e 'smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination'
postconf -e 'inet_interfaces = all'
postconf -e 'mynetworks = 127.0.0.0/8'

postconf -e 'smtpd_tls_auth_only = no'
postconf -e 'smtp_use_tls = yes'
postconf -e 'smtpd_use_tls = yes'
postconf -e 'smtp_tls_note_starttls_offer = yes'
postconf -e 'smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key'
postconf -e 'smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt'
postconf -e 'smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem'
postconf -e 'smtpd_tls_loglevel = 1'
postconf -e 'smtpd_tls_received_header = yes'
postconf -e 'smtpd_tls_session_cache_timeout = 3600s'
postconf -e 'tls_random_source = dev:/dev/urandom'

postconf -e 'myhostname = server1.example.com'

And the second article tells how to modify master.cf to enable SMTPS:

smtps     inet  n       -       n       -       -       smtpd
  -o smtpd_tls_wrappermode=yes
  -o smtpd_sasl_auth_enable=yes
  -o smtpd_client_restrictions=permit_sasl_authenticated,reject
