Hi, The ocserv manual mentions this: ... # The following parameters are passed on the environment. # REASON, USERNAME, GROUPNAME, HOSTNAME (the hostname selected by client), ? But it?s unclear to me what would fill the HOSTNAME variable. In my setup it?s always empty. I was hoping it would contain the hostname that the client intended to connect to, though I?m not sure if that?s known to the server. Which leaves me with 2 questions: 1) What?s the current HOSTNAME variable for? 2) Is it possible to figure out the hostname the client is connecting to? Thanks, Niels
