Hi, This is not a question, just for information. So, I hope not to disturb anyone by crossposting (sorry if I do)... I just wrote a script to create a configuration file and zone files from our openldap machine list, and restart the servers when appropriate. I thought it could be of interest for other people, so here it goes. I know other scripts exist, but I needed a different solution for the following reasons: 1. I didn't want to just write the dns records in our ldap base. Instead, these should be generated 2. I didn't want bind to just access the ldap base, because I want it to be independent of openldap and because of 1 Instead, I wanted to just put all user workstations, servers, switchers and routers, and let a script generate the zone and dhcpd files. Please note that it is configurable: I use it myself to generate the files for multiple domains/subnets from the same base. Just change a couple of lines (I should put it in an independent config file when I'll have time). I wrote these scripts to suit my needs, but you should be able to adapt them to other infrastructures without too much hassle. A few details: - ldap_hosts is the main script. Just adjust the settings to your need. Some are optional; sorry for the poor doc, but the whole script is 300 lines, so just have a look. 'NAMED' stuff is optional. - serials is a little script I wrote to update the serials of the zone files. Adjust your zones list in the script. It needs to access a file named 'serial' which contains your last serial (date/time format), and will update it itself. - I run these things in crontab, every minute. So, dns and dhcp are automatically updated whenever I change the ldap base, and I'm notified by mail about success/failures. - In case of failure, it generates temp files which are only deleted/changed when you change something. So, you won't receive a mail every minute for the same failure. - I use the script to generate only the parts of the zone/dhcpd files I need. I then use "include" directives in dhcpd.conf (include "/etc/dhcpd_ldap.conf";) and in the zone files ($INCLUDE machines.lst). - It works for me but could need some local adjustements! Ok, I think it's all your need. I hope it will be useful to someone someday, feel free to modify it (just tell me, please). Please give me your feedback. Yannick Majoros
