I work for a small Internet provider. I'm getting tired of entering the same information in many places (e.g., new client's IP into DHCP, DNS and /etc/ethers). I'd like to have a system which automates such tasks (OK, I've got a few scripts, but that's not enough). I have a few ideas - could you comment them?
Idea 1) Write a system which keeps the hosts information (and in future - user information) in some kind of a database (file, MySQL or LDAP, probably I'll choose MySQL) and generates configuration files. Advantages: easy to implement. Disadvantages: limited use.
Idea 2) Install a full-blown ISP managemant system, probably based on LDAP - for example the one described here: http://www.tldp.org/linuxfocus/English/September2000/article173.shtml Advantages: it fully automates many mundane tasks, scales very well, has a web interface that can be used by not-so-technical personnel. Disadvantages: hard to implement, such a complicated system can screw up the system in more ways then I can imagine, security hole in this system could cause a total breakdown.
Or maybe there's another system I can use? Preferably something modular, so that I can LDAPize some things (it doesn't really need to be LDAP, but I feel it is the future) and keep good old config files for other stuff? Maybe it'll be better to write my own system (Idea 1), but with scalability in mind - that way I will know what it does and it will minimize the risk of screwing the system up?
Best regards
How small are you? How fast do you plan on growing?
If you're planning on steady growth, it may be well worth your time to jump to a management system now, while it's still easy to import your existing data.
We've been using Optigold here. You need to run their DB on a NT machine with Framemaker, but it does interface well with all our "real" servers (web, DNS, email, etc. all running Debian). Optigold supports LDAP, SQL, telnet, and arbitrary command line server actions, so you could probably migrate from your existing scripts easily.
With web hosting, for instance, Adding a new web host can trigger a script on the web server which dumps the necessary VirtualHost section to httpd.conf. If something breaks, it's still easily editable.
They used to have a trial program where you could use it for free with under 100 customers.
The biggest advantage we found with Optigold, which should apply to any similar system, was the integrated billing. A dedicated system worked much smoother than Quickbooks, especially once our account base passed the 1K user point.
