    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)
    Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
    tcp 0 0 *:mysql *:* LISTEN 21858/mysqld

    getnameinfo failed
    tcp6 0 0 server1.murfettsaut:ssh [UNKNOWN]:3221 ESTABLISHED 12951/0

    Where do i go from here?
    Thanks

    My take on this is that the machine you are ssh'ing from cannot be resolved:
    So netstat sends "getnameinfo failed" to the stderr 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 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.
