Fwd: "Welcome to the VCL" page does not appear...

Subject: "Welcome to the VCL" page does not appear...
To: vcl-dev@incubator.apache.org
Hi guys,
So I was able to finally get the VCL login page to appear. After inputting
the standard userid and password at the login prompt, I was directed to a
blank page. Does anyone have any idea of what may be the cause for this?

Frento,
/var/log/audit/audit.log is a log file, not an executable. Any file you try
to run that doesn't have the executable bit set will give you a permission
denied error - i.e. you don't have permission to execute the file. Were you
trying to view the audit.log file? If so, try
less /var/log/audit/audit.log
Once viewing it, use the up/down arrows to scroll and the 'q' key to quit.
Were you able to check the settings Jim mentioned in the httpd.conf file?

/etc/httpd/conf.d is a directory, and the content above is a list of the files
in that directory. Jim was talking about a file named httpd.conf, which is
probably at /etc/httpd/conf/httpd.conf

No, actually, you missed my point. I was referring to the period. It
should be a slash. (e.g. vcl/index.php)
Here's how it works. Look in your '/etc/httpd/conf/httpd.conf' for
'DocumentRoot'.
If your 'DocumentRoot' = '/var/www/html' then the URL is
'https://<your ip address>/vcl/index.php
If your 'DocumentRoot' = '/var/www/html/vcl' then the URL is
'https://<your ip address>/index.php'
Note: You'll need to have mod_ssl installed to get the 'https'.
Otherwise, just use 'http'.
To help troubleshoot
1. try 'netstat -tan' and look for port 80 (http) and/or port 443 (https).
> tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN
> tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN
2. try 'iptables -L -n' and look for > ACCEPT tcp -- 0.0.0.0/0
0.0.0.0/0 state NEW tcp dpt:80
> ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:443
(it could also be totally blank - which means it's not filtering anything)
3. check the logs for errors
> /var/log/httpd/error_log
> /var/log/httpd/access_log
Hope this helps,

Sorry left off the colon in the URL. But yes, I have that, still doesn't
work.
Re: "Welcome to the VCL" page does not appear...

um, maybe the url should be "https://<ipaddress>/vcl/index.php" ?

Yeah, I have already installed both of those packages. I download opera just
to see if maybe it was an issue with the browser I was using (Modzilla
Firefox) but to no avail. However, Opera actually gave an error message as
oppose to just a blank page like Firefox. when proceeding past the initial
VCL Welcome log in, Opera then redirects me to a an error page which
displays "The remote server or file is not found".
Again, the URL is https"//<ipaddress>/vcl.index.php

Ironically, my installations all have the latter address. What operating system is the bugged one on? If it is RedHat, odds are you are missing the mcrypt-php and libmcrypt-php packages as they are not in the default repository for the OS.

I often found that when I got the blank page it was because I forgot to restart the mysql or the vcld service.

Thanks for the suggestions James,
I checked the conf.php file and it appears that all the values are correct. Luckily enough we have two test machines we're using to implement VCL. The other machine is running CentOS5 and it seems to be working fine. In comparison and contrasting the working machine and the machine that doesn't display the "Welcome to VCL" page, I noticed that our URL address slightly differed under page info. The working machine displays the address https://'ipaddress'/vcl/index.php. However, the machine that doesn't work displays the address https://'ipaddress'/vcl/index.php?mode=selectauth in the page info section.
Do you think this might have something to do with the blank page error? Besides checking the Apache logs, I'm about out of possible solutions to the problem....

Hey Frento,
There a couple a possibilities that come to mind that you could check.
One would be to double check your conf.php file for any incorrect values or typos. In particular, double check baseurl, script, cookiedomain, and homeurl.
The other idea I have is to make sure that all of your php packages are installed. I've had a few installations where somehow I missed one and it cause errors like what you are describing.
php-gd
php-json (if your PHP version is < 5.2, this is not required)
php-mcrypt
php-mysql
php-openssl
php-sysvsem
php-xml
php-xmlrpc
php-ldap (if you will be using ldap authentication)
Hope this helps,
Patrick Sigmon

Not sure if this is part of the problem but I don't see a referring URL from
my index.php page when I view page details. Just thought I would make
mention of that.
