Hostname Shows (none)

May 7, 2009

I have a server with RHEL 5 installed. The problem is that the server shows the output of the hostname command as (none). I checked the /etc/sysconfig/network file and it shows the correct hostname. I also tried to change the hostname in the /etc/sysconfig/network file and restart the server. But hostname command still shows (none).

Shell_exec Shows Nobody

Mar 13, 2008

I am running into a few problems when it comes to using the above command. No it is not being blocked in the php.ini file. The issue has to do with permissions. On my old server everything worked fine until I moved over to this new server.

$who = shell_exec("whoami");
echo "$who"; 

When I run that commend on the old server I got that users username. Which, makes since as that means anything created via PHP would be owned by that user. In fact, every other host I know of was like that. But, on the new server when I run the commend it shows up as "nobody". How can I fix this so my commands will run properly for me and my users?

Squid - Shows Clients IP

Oct 7, 2007

Im currently running cent0S 5. I recently just installed Squid Version 2.6.STABLE6 for a client to enable him to use as proxy. However it seems that sites like and are resolving back to my clients IP address and not the servers.

There is only one IP on my server and I think the problem may deal with X-Headers? (correct me if I am wrong)

Is there any way to use the server IP address for when my customer is using the proxy server.

Dns Report Shows Failure

Jun 5, 2007

My VPS is setup and now when I did a dnsreport for my site, it shows:

Number of nameservers
ERROR: You have 2 nameservers, but both are on the same IP! This is not a valid setup. You are required to have at least 2 nameservers, per RFC 1035 section 2.2.

Is this a big problem?

The report [url] also shows other failures. Are there any critical ones that I need to take care of? How do I do it?

Why Wndows 2008 Standard Shows Its IIS Front Page Only

Dec 13, 2008

Why Wndows 2008 standard shows its IIS front page only

I am using windows 2008 standard version 64 bits

I am using an external DNS service and using none of Windows roles

I disabled the firewall completely

When I run IIS i can access to its front page from another machine but when I run jboss the browser can't get access to my web site front page! They both use port 80

Does ISS has some sorts of hidden privileges in Micorosoft which is not surprising

I am about to revert back to Windows 2003 if I can't find a solution to this problem. Or do I have use a certain role for remote access?

How To Use Appache (HTTPD) With LXAdmin? Only Apache Homepage Shows, Not My Pages

Apr 30, 2009

I've got a VPS with XenSmart, and I'm running CentOS. Recently, I have been needing to redirect my users to 'www.', since if they don't put the 'www.' in front of the domain the vB forum doesn't run properly. Though, to do this, I edited the .htaccess file and was using the 'mod_rewrite' command, but this requires Apache.

So, on my VPS I've installed Apache, and set LXAdmin to use 'httpd' instead of 'lighttpd', though now my web pages wont show up and all I've got is the default Apache web page:


How am I able to use Apache (HTTPD) and have it load my current forum? My current forums hosted in:
