Thanks for the information. The username/hostname/domainname determination is
really not robust enough. I've today compared the stuff with some of my other
GNU Autoconf stuff and the result is a script uhd.sh which I want to use for
Apache 1.3.2. I've already tested it under FreeBSD, Linux, SunOS and Solaris
now and it is both more robust and results in more correct output. I append
it below. Just run it as
$ ./uhd.sh [EMAIL PROTECTED]
and
$ ./uhd.sh -n [EMAIL PROTECTED]
Both times your (semi-correct) e-mail address should be printed. The first
time newline terminated, the second time without a newline. Please give
feedback if it works for your situation, too.
Thanks.
