Several people have asked me how to make a working /etc/named, and
programs using it, for Concentrix. The following description is,
unfortunately, a bit more sketchy than I hoped I could produce,
because I didn't document things very well as I did them many months
ago. There are probably some mistakes, so please post corrections to
this newsgroup. I may not have time to answer personal mail on this
subject.
What follows should work for Concentrix 5.0 or later. Earlier
versions use 4.2 BSD networking code. It is possible to bring up
named on Concentrix 4.0 (I did it), but not as easy.
Step 1. Get the BSD networking sources code. The place that I got it
from is uunet.uu.net, via anonymous ftp, in the directory
/bsd-sources/src/network, as a bunch of compressed tar files. It may
be available from other places. This code was released from Berkeley
later than 4.3 BSD Tahoe.
Step 2. The following addition is needed in the "include" directory.
*** /public/bsd-sources/network/include/netdb.h Sat Jul 9 14:38:10 1988
--- ./include/netdb.h Mon Oct 30 12:47:49 1989

Step 3. Build libutil.a and libresolv.a. The sources for libutil.a
are in lib/libutil. The sources for libresolv are in lib/libc/net,
using the makefile "Make.resolv". I had to modify these makefiles
slightly, adding -I../../../include so that it would use the include
files from the new code. Also, I later found several more files that
needed to be in the libraries, so I added rcmd.o rexec.o strcasecmp.o
to the object files in libresolv.a. Install the libraries where ld
will find them, such as in /usr/local/lib.
Step 4. Build named. A few changes to the Makefile were needed:
CFLAGS= -O ${DEFINES} -I../include
RES= -lresolv
Install named and its configuration files. You'll have to read the
documentation for this.
Step 5. Build programs using the resolver library. The programs I've
compiled so far are: ftpd, rlogind, rshd, telnetd, finger, ftp,
rlogin, rsh, telnet. Also sendmail, though it requires a bit of extra
work. In most cases, all that is needed is to add -I../include and
-lresolv to the appropriate places in the Makefile and compile. For
ftpd, I had to change the function named "popen" to "ftpd_popen" and
"pclose" to "ftpd_pclose" in popen.c.
That should do it!
