Anyone interested in this? ------- Forwarded Message From: jordan@heuristicrat.com (Jordan Hayes) Subject: Re: Virtual top-level home pages on the same machine [ by popular demand; I did this a few months ago (a Sparc I have here has 10 addresses! Thanks, Tim!). I have since seen a patch from some luser on the net that's hundreds of lines long. I couldn't even tell if it did what I thought it did. Anyway, here's what I did. I did something similar to inetd so that you can have multiple inetd's running in the same way. Fun city. ] There is a configuration item in the CERN httpd called "hostname" but it appears not to be used for anything. So I use that. If you have the CERN 1.3 source, the server lives in Daemon/Implementation. - - In HTConfig.h (around line 45), I added a struct in_addr to the struct _HTServerConfig - - In HTConfig.c (around line 1100) I initialize sc.addr.s_addr to INADDR_ANY - - there's a big pile of code that parses the config file. When you get to the "hostname" directive (around line 1755), I added: struct hostent *hp; if ((hp = gethostbyname(vec[1])) != (struct hostent *)NULL) bcopy((char *)hp->h_addr, (char *)&sc.addr.s_addr, sizeof(sc.addr.s_addr)); - - In HTDaemon.c (around line 1324) I changed the line sin->sin_addr.s_addr = INADDR_ANY; /* Default: any address */ to sin->sin_addr.s_addr = sc.addr.s_addr; - ----- If the "hostname" directive doesn't exist, this is a no-op; the bind() call just listens on all interfaces. If it does exist, and we can resolve it (make sure there's an A record for the particular interface that you want to listen on), it gets used instead. Use the -r argument to httpd to have separate config files.
