Title: chatroom/CGI/HTML Q's
Post by: Master of Reality on 30 June 2002, 23:42

I'm using Linux to run my server so this is in the linux forum.

I just got BlueChat, which enables chat logging.
It uses CGI. I am almost clueless about CGI stuff... Can i just make a directory called 'CGI-BIN' and use it for the CGI scripts??
Do i even need a cgi-bin for the .cgi scripts with apache?

You don't needa CGI-bin but is is common practice as it is safer.

I have a good link for you (MOR) about writing CGI and safety implications but you will have to wait till tomorrow because i have forgotten it...

Well... once i get the CGI figured out, the chatroom will be up and running.

is there a way to copy stuff (like an image) through ssh to another computer?

Yes, but it's called "scp".  Do a "man scp".

Ok, before you ask, here's an example:

scp myimage.jpg [email protected]:/directory/on/remote/machine

There is a line you have to uncomment  in the httpd.conf called:

AddHandler cgi-script .cgi

And make sure your Perl scripts end in *.cgi.

I made the directory '/var/www/html/cgi-bin' it has the same permissions as /var/www/cgi-bin but my browser says it cant fins the directory or file when trying to access bluechat.cgi which is in the cgi-bin.

I'm not sure why you have a /var/www/html/cgi-bin when you have a /var/www/cgi-bin.  What I normally do is make it so I can run CGI programs from anywhere under my web root.  You can do this in the section in the httpd.conf where the /var/www/html directory is defined.  There should be an "Options" tag.  I usually set it to:

Options All MultiViews ExecCGI

I also set:

AllowOverride All

which will allow you to use ".htaccess" files etc.  You should then be able to put CGI files anywhere under your web root and they will be executed.

Also note that the scripts you put in there need to be executable and contain no errors (test them on the command line before trying to execute them through Apache).

When i tried to execute it, it said '; bad interpreter: No such file or directory'.
what does this mean?
