I am trying to get proftpd working.  When I start it by typing proftpd it comes back and says "unable to determine ip address of 'dhcp-112-156'" which I beleive is the name that is assigned to me by ATTBI.  I have had proftp working in the past but have reloaded my system since then so this is a new install.  I am running RH7.2.   

I have done a google search without much luck. 

I believe the solution is to tell proftp the ip address but I have not figured out how to do it.  I would appreciate any help with this.

TIA
