Using Helm with SimpleDNS
Helm us es the HTTP interface in to SimpleDNS. By default SimpleDNS will not allow Helm to call
its HTTP interface, so some additional c onfiguration of SimpleDNS will be required.
To configure SimpleDNS to be co ntrolled by Helm you will need to make som e small am endments
to the SimpleDNS configuration file.
Navigate to the SimpleDNS install fo lder, and open the sdn s plus.ini file in any text editor. Thi s
file can be found in the root install a tion folder for Si mpleDNS. On e sect ion of the initialisation file
is called “[HTTP-C ommand ]”. Wi thin this sectio n there a number of option s:
HTTPBind : This is the local IP address that the HT TP interface is listening to. By default
this is set to ‘*’. This i s a wildcard and will work fine, but for better security en sure that
the IP addres s that H e lm use s t o c a ll the DNS serv ice is entered here instead. If you
have an inte rnal and external network you sh ould ent e r the internal network IP address.
This will stop possible conn ection s from outsid e of your network .
HTTPPort: By default SimpleDNS will be listening on port 8053. There is n o reason to
change thi s although chan ging this to a less known port can help against mor e servic e
scan att e mpts .
HTTPACL: Enter into this the IP address of the Helm contr o l server. If SimpleDNS is on
the Helm Control server then you ne ed to set thi s IP address as the same IP as the
HTTPB ind ad dress. This e nsure s th at only the c o ntro l se rver c a n send re quests t o the
DNS server . You should als o add 127 .0.0 .1 to this line as SimpleDNS may need to
communicate locally from this IP. So if your IP is 1.2.3.4 , the full line wo uld read:
HTTPACL=127.0.0.1 1.2 .3.4 (note th e spac e betw een IPs) .
HTTPPW : If you are usin g Simple DNS 4, it defaults with a password being set. This will
cause issu es, so if you are using this version you should delete this line from the
sdnsplus .ini file.
You will now have to restart the SimpleDNS service in order for th ese ch anges to be made. Yo u
can te st th at the configuration is co rrect by access http://1.2.3.4:8 053/status where 1.2 . 3.4
should be replaced with the communication IP you h a ve specified in Helm for th e DNS server .
If you have trouble getting Helm to work with SimpleDNS, ensur e the following:
- Mak e sur e the IP address specified to c o mmunicate with the SimpleDNS service is correct , an d
resolv es.
- The SimpleDNS service i s running and has n o t crashed.
- The ACL list in the SimpleDNS configuration file co ntains th e IP address that the control server
is communic ating from (as outlined ab ove).
- MS XML 4 h a s been instal led on the server. You ca n tell this i s the case b e cau se you can acce ss
the SimpleDNS service thr ough the web browser on the server , bu t Helm still has problem s .
