I have now spent more than a week trying to sort out the various troubles I have been having with my Ubuntu linux server. I have upgraded to the most latest versions, then given up and downgraded. I even bought a new hard disk and did a totally clean, new install of the 6.06 LTS server release to get the most absolutely stable version of Ubuntu possible. Yet, I still continue to have issues with the Postfix mail server and now Samba/CUPS printer sharing is working no longer either. I just have to give up, far too much time and energy has been spent to this.
I have consulted and used most of the available how-to guides and installation manuals, including:
- The Perfect Setup – Ubuntu 6.06 LTS Server (Dapper Drake): http://www.howtoforge.com/perfect_setup_ubuntu_6.06
- The Flurdy.com Postfix setup guide: http://flurdy.com/docs/postfix/
I suppose that in most cases most contemporary operating systems work, most of time. But I think these things are still far too fragile to really serve people reliably — each server needs couple of admins to hold its hand, rather than the other way around, having the reliability needed to serve its users.
