Topic: Unable to get CGI scripts to run

[del]

Hi All,

I know this has been covered many times but after searching on here and on Google I have finally conceded defeat and realise I need some help
I have tried all the normal things like uploaded again as ASCII, CHMOD to 755 etc. I can get the exact same script to run OK on my web hosting account so I know that everything is OK in the .pl file but I still get the dreaded "Internal Server Error" Do I have to enable anything on my server, I am using the primary i-bay so I guessed that I wouldn't have to but maybe I'm wrong (wouldn't be the first time ) Any help is greatly appreciated.

Regards,
Del

I think cgi scripts need to go into <ibayname>/cgi-bin, and you need to have CgiBin enabled for the ibay:

db accounts show <ibayname>
<ibayname>=ibay
    AllowOverride=All
    CgiBin=enabled
    FollowSymLinks=enabled
    Gid=5006
    Group=admin
    Name=<ibayname>
    PHPBaseDir=/home/e-smith/files/ibays/<ibayname>/:/tmp/
    PasswordSet=no
    PublicAccess=global
    Uid=5006
    UserAccess=wr-group-rd-everyone

Hi mmccarn,

I am using the primary i-bay so when I run that command I get this output:

primary=system

I have tried creating an i-bay called sle and I still get the Internal Server Error when running the cgi script, when I run the command for that i-bay I get this output:

sle=ibay
    CgiBin=enabled
    Gid=5002
    Group=admin
    Name=sle
    PasswordSet=no
    PublicAccess=global
    Uid=5002
    UserAccess=wr-group-rd-everyone

The only difference I see is in your example is line 4 Gid=5006 is Gid=5002 and line 10 Uid=5006 is Uid=5002
So I'm at a loss with it.

Is there anything interesting in your log files?
/var/log/httpd/access_log (is your script being requested?)
/var/log/httpd/error_log (is your script generating an error within apache?)
/var/log/messages (is your script logging something useful here?)

This is what is shown -

Access log

Did you put the scripts into the cgi-bin subfolder that is in the ibay (automatically created by smeserver) ?

[TerryF]

Maybe I am just barking up a tree however,

When I go to that URL, http://ddj.homelinux.com/contact.html, the "Send Email" button calls the script from http://192.168.0.3/cgi-bin/mail_ht.pl

Maybe change the local ip to the domain address..

When I do that I can see the script, so I suspect permissions etc are also in the game.

[TerryF]

I put a copy of your script in my primary iBay cgi-bin folder with permissions of 0755 and it worked fine.

Hi Janet & Terryf,

Janet, yes I have put it in the cgi-bin folder

Terry, I changed that to a local address late last night to try it locally, it was http://ddj.homelinux.com/cgi-bin/mail_ht.pl I've now put that bask in there. One thing how did you get the script? I thought that the cgi-bin was not available to the public

Terry what setup do yuo have? I have my server in server only mode with http forwarded from the router would this make any difference?

When I access the script using the URL http://ddj.homelinux.com/mail_ht.pl it displays it as a text file, simple save as and I have it.

First test was on a SME8 VM with all updates, Server Only. Forwarding should not be an issue, make sure of the permissions.

This is where I have now put the script as it is a stand alone SME8 box remote from me, again in server only mode permissions set to 0755, it will be deleted shortly - Test Mail Script

Where is that server, is it at your home/office etc and simply run off your adsl line?

Ah I see, yes that file was just put there for testing (I wanted to see if I could access it outside of the cgi-bin)

Where is that server, is it at your home/office etc and simply run off your adsl line?

That is correct (at home) in Server Only (Virgin 100mb)

All permissions are 0755.

[TerryF]

If you issue the following at a command prompt without a name

 db accounts show

You will get a list of all accounts, in particular it will list the settings for the primary iBay.

This is the details for the server that I had the script on:

[root@bschclassroom ~]# db accounts show
Primary=ibay
    CgiBin=enabled
    DriveLetter=W
    Group=shared
    Modifiable=no
    Name=Primary i-bay
    PasswordSet=no
    Passwordable=no
    PublicAccess=global
    Removable=no
    UserAccess=wr-admin-rd-group

[del]

This is what I get after running the command -

Primary=ibay
    CgiBin=enabled
    Group=shared
    Modifiable=no
    Name=Primary i-bay
    PasswordSet=no
    Passwordable=no
    PublicAccess=global
    Removable=no
    UserAccess=wr-admin-rd-group

[TerryF]

So as long as the permissions are set Ok, there would seem to be no reason why that script would not run.

Got me, it needs a smarter mind than mine to suggest further avenues of investigation.

There has to be something that is preventing the execution..

I tried it on another remote system in a iBay other than the primary, no probs as long as the permissions were 0755, what are you using to upload the file with, I am using WinSCP

I can get the exact same script to run OK on my web hosting account so I know that everything is OK in the .pl file but I still get the dreaded "Internal Server Error"

You have to read httpd/error_log to determine what the problem is. Just saying "it doesn't work" isn't sufficient for anyone to help you solve the problem.
