What do the logs say about it?
Was the zone transferred successfully?
- Does it say something about a failure on any line?
If digs against slave aren’t working, your transfer probably didn’t complete!

Typos in zone or named.conf.local
- Dots?? (after NS records, at end of ptr record, end of SOA lines)
- Semicolons
- OTher syntax errors
I can’t wget
My slave isn’t working
- Misconfigured named.conf.local
TTL set too high, you have to wait a long time for new refresh.
A record pointed to wrong host.

Conceptual understanding
- What does delegate mean?
- Are you blindly following slides or do you try to understand what they are saying?
- For the exam, it will be VERY difficult to rely on slides to tell you what to do, though it is open note.

System level users vs Database users
- They are not the same!
Most problems boil down to:
- Did you create the database
- Did you execute the correct GRANT statement on the database
- Did we allow remote connections?
Examples:
- GRANT ALL PRIVILEGES ON 'foo'.'*' to 'bob'@'144.38.195.%' IDENTIFIED BY 'secret';
- GRANT ALL PRIVILEGES ON 'foo'.'*' to 'bob'@'144.38.196.%' IDENTIFIED BY 'cows';
- GRANT ALL PRIVILEGES ON 'foo'.'*' to 'bob'@'localhost' IDENTIFIED BY 'cows';

Can you send an email to someone in the domain?
Send out to world?
Send from world back to domain?
MX record found? (If not, fall back to A record)
- You CAN do a dig test to see if it is working.
Listening on ports (do a netstat -natp) (This is good for looking at ANY service)
Logs?(Paniclog, mainlog?)

Can you visit the website?
Can you dig the FQDN and get an IP?
If it shows a different page than what you were expecting:
- DId you enable the virtual host?
- DId you create the correct document root?
- Is there content?
