Two error_log errors I can't figure out. I posted this on some other forums but was told to try linux as some feel these are linux errors.

First error;

[client 192.168.1.74] PHP Notice: Undefined index: HTTP_HOST in /var/www/html/index.php on line 28

The line at position 28 in index.php is;

$http_host = explode(':', $_SERVER['HTTP_HOST'] );

Client 74 is actually an LVS load balancer. It connects to the site constantly to make sure the web server is running. I'd love to figure out why this error is showing up though?

The second error;

[Thu Jul 12 12:38:37 2007] [error] [client 192.168.1.200] File does not exist: /var/www/html/relativepath, referer: http://www.domain.com/index.php?opti...&id=2&Itemid=1

I simply cannot find a solution on this anywhere on the net. Perhaps someone could guide me with a few questions to figure out a starting point?

well the HTTP_HOST header is used to know which website is to be served. with apache and IIS etc.. you can have site1.com, site2.com etc... and so the web server needs to know what site to give, which is obtained from the http_host header, normally taken from http://www.site1.com/some/page but if you are monitoring with LVS then you're probably not forming a url at all, just sending the string "GET /" to the http port, without any HTTP_HOST or other http headers in it. often that's not a *problem* as there's only one site or something, but the host header is required as part of the formal definition, so it is a legitimate complaint. PHP warning levels can be tuned to remove this, ( http://uk3.php.net/errorfunc ) but if possible, monitor the site better in the first place.

the other one seems very self explanatory... does it exist?

First, thanks for the input.

Correct. Snip from lvs.cf;

virtual HTTP {
active = 1
address = 192.168.1.150 eth0:1
vip_nmask = 255.255.255.0
port = 80
send = "GET / HTTP/1.0\r\n\r\n"
expect = "HTTP"
use_regex = 0
load_monitor = none
scheduler = wlc
protocol = tcp
timeout = 6
reentry = 15
quiesce_server = 0
server cweb92 {
address = 192.168.1.92
active = 1
weight = 0
}
server cweb93 {
address = 192.168.1.93
active = 1
weight = 0
}
server cweb94 {
address = 192.168.1.94
active = 1
weight = 0
}

What do you mean by monitor the site better? Also, the error along with LVS constantly hitting the web servers are creating HUGE logs. I'd love to not log the LVS server hits to the web servers.

>the other one seems very self explanatory... does it
>exist?

Sorry, again, not sure here, does what exist? If it were self explanatory to me, I would have fixed it .

i mean send fully valid http headers, not just a crude GET.




your error message clearly states a file does not exist. in those exact words. which you pasted yourself.

>i mean send fully valid http headers, not just a crude >GET.

Still don't know what that means but I'll research it, I'm sure I'll find an answer.

>your error message clearly states a file does not exist. >in those exact words. which you pasted yourself.

I don't get people like you. Why do you even bother replying to anyone if you're going to have attitude? I already know the freaking file is missing but I've already explained what's going on.

Please, don't bother replying, I'll find someone who actually will help.

Lordy, the net is just getting weirder all the time.

you seriously don't get forums do you? if you keep asking the same question despite useful information which others would say suitably answers your repeated question, then either you're not reading it or you don't understand it. if it's the former, then take your time to actually read the answer, and if it's the latter, ask for further clarificcation. in your case, you have your own error which tells you that a certain file, the name of which is printed right there, was requested and not found. what's to not understand? what else am i supposed to tell you??

>you seriously don't get forums do you?

Gee, let's see. I started online in the BBS days, I'm guessing I've got a sense of how forums work, it's the people that have changed.

When someone is really trying to help someone, they don't just keep repeating the obvious in a negative tone as you have been. Why bother helping if you're going to have attitude?

>if you keep asking the same question despite useful information >which others would say suitably answers your repeated question,

Your help has not been helpful, at all, I've already told you what is going on and you keep repeating the things I know. If you really care to help, then stop acting like some king shit god know it all and ask me a few questions that will help me to give you ADDITIONAL information so that you can actually help me.

>in your case, you have your own error which tells you that a >certain file, the name of which is printed right there, was >requested and not found. what's to not understand? what else am i >supposed to tell you??

Maybe you should re-read my post. Like I said, I don't care to be helped by someone who's just trying to make me feel crappy for not knowing something. I've been building freaking networks for the last 20 years, I don't act like an ass when someone is wanting to learn or figure something out. Sometimes it's very obvious, sometimes it's not. In this case, it's not. We can't know everything under the sun.

Thanks for your help, I'll keep looking for an answer or repost this.
