getnameinfo failed

[Paul7277]

Hi All,
I've been slowly working my way through http://www.howtoforge.com/perfect-server-ubuntu8.04-lts but i am stuck on this error after i do, netstat -tap | grep mysql i get

getnameinfo failed
tcp 0 0 *:mysql *:* LISTEN 21625/mysqld

If i do hostname
root@server1:~# hostname
server1.murfettsautoelectrical.com.au
root@server1:~# hostname -f
server1.murfettsautoelectrical.com.au

Then
root@server1:~# netstat -tap
Active Internet connections (servers and established)

Where do i go from here?
Thanks

My take on this is that the machine you are ssh'ing from cannot be resolved:
tcp6 0 0 server1.murfettsaut:ssh [UNKNOWN]:3221 ESTABLISHED 12951/0
So netstat sends "getnameinfo failed" to the stderr (http://en.wikipedia.org/wiki/Stderr#Standard_error_.28stderr.29) stream when the name resolution fails.

When you issue the grep command you're seeing two things.
1.) getnameinfo failed - stderr stream because of above
2.) tcp 0 0 *:mysql *:* LISTEN 21625/mysqld - stdout (http://en.wikipedia.org/wiki/Stdout#Standard_output_.28stdout.29) stream results of grep

So you can either ignore it, it's not really a problem, or fix the name resolution for the box you're ssh'ing from.
