Re: Installation problems

Hi Simone and Rick,

I found problem number 2.  I did something wrong with the loopback which
killed network and generated the IP conflict errors but removed them and now
at least they can see the network.

On problem 1 I don't have the virtual IPs in haresources.  For some reason I
can't seem to get the syntax right because it keeps throwing errors.  This
is what I have

192.168.0.100  virtual web server
192.168.0.101  real web server 1
192.168.0.102  real web server 2

192.168.0.200  virtual mysql server
192.168.0.201  real mysql server 1
192.168.0.202  real mysql server 2


Thanks
