04:27 pm - Hello, tentacle support?
Subject line from here, via waistcoatmark. Silly, work-safe.

I am trying to establish a web site and put a perl script to run a Wiki on it. I have uploaded the software correctly, unzipped it, extracted the tar archive and put the wiki.pl script into ~/htdocs/cgi-bin/ . I have made sure that both the wiki.pl script and the cgi-bin directory have 755 permissions. When I visit http://www.appropriatesitename.com/cgi-bin/wiki.pl then it does not execute the script, it merely displays the code of the script in the browser. However, when I open a shell, cd to the appropriate directory and execute perl wiki.pl from the command line, it produces a perfectly-formed HTML page that I would expect to see. I do not believe there is anything further I need to do in order to enable running scripts on the web site.

Any advice, please? aTdHvAaNnKcSe to anyone who can help.

ETA: We now think it's a problem at their end. Their engineers are looking at it and hope to have sorted it out in 24 hours. If not, I shall phone again. Thank you for the suggestions anyhow, but I doubt there's much anybody can do about it from this end in that case...

You probably need to set the first line of the scripts to
#!/path/to/perl/executable

try going to the directory and running ./wiki.pl - any luck?

and/or editing the httpd.conf file to tell it that the cgi-bin directory is to be treated as an script-aliased (or something) directory, if it doesn't think it is at the moment.

If you're running apache, the cgi-bin directory is usually in ~/cgi-bin not ~/htdocs/cgi-bin

I assume ~ is his home directory and ~/htdocs/ is the web root. I may be wrong though.

You assume correctly!

Yup. Or sometimes make sure the right extenstions are being treated as scripts. But yeah, all the things you just said I was going to. Though I always forget what that first line looks like so I wasn't actually going to quote it. :)

It is. :-)

Yes.

In which case it's probably that the webserver doesn't know that this is a script directory.

Does the httpd.conf have something that looks like
#
# ScriptAlias: This controls which directories contain server scripts.
# ScriptAliases are essentially the same as Aliases, except that
# documents in the realname directory are treated as applications and
# run by the server when requested rather than as documents sent to the client.
# The same rules about trailing "/" apply to ScriptAlias directives as to
# Alias.
#
ScriptAlias /cgi-bin/ "/xxx/cgi-bin/"

[Error: Irreparable invalid markup ('<ifmodule mod_cgid.c>') in entry. Owner must fix manually. Raw contents below.]

In which case it's probably that the webserver doesn't know that this is a script directory.

Does the httpd.conf have something that looks like
<pre>#
# ScriptAlias: This controls which directories contain server scripts.
# ScriptAliases are essentially the same as Aliases, except that
# documents in the realname directory are treated as applications and
# run by the server when requested rather than as documents sent to the client.
# The same rules about trailing "/" apply to ScriptAlias directives as to
# Alias.
#
ScriptAlias /cgi-bin/ "/xxx/cgi-bin/"

<IfModule mod_cgid.c>
#
# Additional to mod_cgid.c settings, mod_cgid has Scriptsock <path>
# for setting UNIX socket for communicating with cgid.
#
#Scriptsock logs/cgisock
</IfModule>

#
# "/xxx/cgi-bin" should be changed to whatever your ScriptAliased
# CGI directory exists, if you have that configured.
#
<Directory "/xxx/cgi-bin">
AllowOverride None
Options None
Order allow,deny
Allow from all
</Directory>
</pre>

If so, move your files to /xxx/cgi-bin or change the conf file to reflect the location of the files (I'd say preferably not under htdocs, but that's just me)

Hmm. Now you're reaching the point where I am highly confused. :-)

There isn't a httpd.conf file anywhere within ~ or subdirectories. Where should I set one up, please?

It's the configuration file for the webserver (again, assuming you're using apache). If the server's running, you already have one of these. I don't know where it will have been installed on your system (on mine it's in ~/apache/conf) but you could try a file search.

I assume the web server is running too, because a raw HTML file in the htdocs directory works.

find / -name apache (which I got from here, though this isn't the Wiki I'm running!) returns a lot of Permission denieds and nothing else.

I think you might have to talk to whoever maintains the server, then, and ask them where to put your scripts.

Thanks very much for your help, anyway.:-) Am talking to the tech support line, managed to get someone Linux-competent by good fortune, he has tried all the obvious things and hasn't spotted anything very silly that I've done, and he has escalated it to second level support.

Ah, if it's a commercial outfit they might have things set up in all kinds of odd ways :) Good luck with it!

Looks like a problem at their end and their engineers are on their server config. Doesn't look like much we can do about it from here.
