Apache Web Server

Dapernia · 01-23-2005, 09:03 AM

Hi friends!:

I`ve installed Apache web server on my computer with Red Hat 9, and it works just fine on Linux, but I have two problems:

- The first one, is is when i try to access a web page from other computer with windows XP in the same network. I execute the ping command from windows computer and the linux host answers fine, but i can`t see any page.

- The other problem is when i try to execute cgi programs. The browser writes "500 internal error"... I have a compiled cgi script with "C" commands but it doesn´t work. Not even scripts written in Perl work.

I thought it was because it didn`t have Perl or C compiler installed on the computer but it looks like it has them.
Can anyone help me out please?

Thanks!!!

What error do you get?

What permissions did you set on the scripts? Take a look in your error_log file it should give more details.

The error is when i try to access with the Browser any page, it tries to connect to the server but it never does, and after a very long time it`s still trying to find the page (this happens in windows) finally it says that the host is unreachable

About the permissions i`m gonna take a look into the log file...

Thanks!!!

Can you post the output from:
netstat -nlp
iptables -nL

Thanks a lot David!!!

You know?, I stopped the iptables and it works fine, but is that right? what problems could that
bring me up?
Now, the other problem is with the .cgi programs (The server writes Internal Server error)... I give permissions with chmod a+x to the script but it doesn't work, i checked the error log file and it says this:

I would definitely not run a server without a firewall. Suggest you configure iptables to work with apache. There are numerous scripts available that will do that. SInce you're running Redhat, the easiest way would be to just use the gui and MainMenu --> System Settings --> Security Level and allow http.

But you definitely don't want to run without some kind of firewall.

Sorry to interupt but how do you install apache web server without a C compiler. Most standard installation involves compiling using C compiler first. Are you using apache binaries to install? I am using httpd-2.0.50-i686-pc-linux-gnu.tar.gz binaries under redhat 9 and there seems to be some problem.

david_ross · 01-26-2005, 03:03 PM

Without a compiler you will need to use a binary - probably an rpm.

Dapernia, what are the permissions on those scripts? Are they executable?

AzidStar · 01-27-2005, 03:57 AM

Could you post the C code for you CGI-scripts?

One common problem (except the chmod problem) is that people forget so put

printf("Content-type: text/html\n\n");

in the beginning.
