CGI on OpenBSD 5.6 httpd

slamet has asked for the wisdom of the Perl Monks concerning the following question:

I cannot find any documentation on how to get CGI going on OpenBSD 5.6 httpd. (Starting with 5.6, OpenBSD ships its own http daemon.) And I am a newbie with CGI. I have something like the following: hello

!#/usr/bin/perl

print "Content type: text/html";
print "hello world";
[download]

I have done "chmod 755 hello", but when I call the address

curl localhost/hello
[download]

I got the whole file content, instead of just "hello world". I have poured over manpages for httpd and httpd.conf, but still cannot fix this. Many thanks for your help.

Line 1 - Change `!#` to `#!` Line 2 - add `\n\n` `#!/usr/bin/perl print "Content type: text/html\n\n"; print "hello world";` [download] Move the script to the `cgi-bin` folder and try `curl localhost/cgi-bin/hello` poj	[reply] [d/l] [select]

Are you sure that `curl localhost/hello` will contact your http server? I would try `curl http://localhost/hello`. Still, your webserver does not seem to be set up to treat `hello` as a CGI file. Maybe naming the file `hello.cgi` would help, if the webserver by default is set up to treat executable files named `.cgi` as programs producing output.	[reply] [d/l] [select]

I cannot find any documentation on how to get CGI going on OpenBSD 5.6 httpd. That's right, httpd by itself doesn't do plain cgi (only fastcgi). You need slowcgi(8).	[reply]

Thanks for all the input. I fixed the typo on #!, renamed the file name, created cgi-bin dir under the chroot dir (and both have permission mode 755). Re comment on "curl localhost/..", what I meant was "curl http://ip address/..". Re slowcgi, according to the manpage, it actually is the implementation of fastcgi. :-) I suspect there is something on httpd.conf that I am missing, but I copied it from the manpage. `prefork 2 server "default" { listen on egress port 80 } types { text/css css text/html htm html text/txt txt image/gif gif image/jpeg jpg jpeg image/png png application/javascript js application/xml xml }` [download] All in all, I am still stuck.

Actually it does and it has a good sense of humour for the name. http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man5/httpd.conf.5 Anyway, I just found this blog post. Thanks to all who responded to my inquiry. http://www.protoc.org/blog/2014/11/23/first-thoughts-on-the-new-openbsd-httpd-server/ Cheers	[reply]
