Rack PDUs At The Co-Lo? Zero U Never Works
Nov 9, 2009
I have had bad experiences with zero-U PDUs (i have only tried the APC ones). They keep getting in the way of equipment when you put them in the back of the cabinet .... I usually end up just having them standing up in the back of the cabinet and zip tie them to something so they dont fall down.
Am I just stupid and using these wrong or do other people have this issue? if you have an extra long server that sits out the back it bumps into the PDU so you got to nestle the PDUs into a corner of the cabinet.
What PDUs is everything using in various co-los? I might go with the 2U rack PDUs but with the need for 2 of them that is 4U wasted (and also since they are not very long you need some long cable runs for all of the equipment to plug into them)..

Can anyone recommend, or know of, a metered PDU that has integrated reboot functions?(e.g. LAN access to turn on/off outlet.)

moving to a new colo provider, at Equinix in Ashburn. We are looking to lease a full cabinet of space.
More than one quote we have received includes a charge for us to buy the PDUs. The pricing for the PDUs seems to be market-rate, and the PDUs seem to be good quality based on what I've read here (usually APC).
My question is: Is this now standard practice that the customer owns the PDUs? Our needs are not special in any way -- just 2 PDUs with 20-25 ports on each.
I don't mind paying for the PDUs, but my concern is the responsibility. I would prefer that we are not responsible for the PDUs. What if one of them fails? I guess we'd be down potentially for a few days while a new PDU is purchased. Meanwhile, if the PDU was not our responsiblity, the colo provider would probably have some spares on-hand and we'd be up and running in a matter of an hour or less.

With all the high power servers/blade servers, the 40A (@ 110V) power limit is way too small. I am wondering if there is any colo space targeted for high density application, e.g. with 10 KW/cab limit for 60A @ 208V power drops. Does anybody know of such high density colocation space? East coast is preferred.

I just installed wamp here on my laptop to set up a developer machine for my website. I am used to going into the browser and just typing in "localhost" and having it bring up the test website. I'm sure there is probably something wrong with the configuration of the wamp files because it works for 127.0.0.1.

php passthru() works from PHP CLI but not web
I have a script which I use to restart processes and I am trying to make it work by clicking a button on the word. It works from running it from php command line but I can never seem to get it to work through the click of a button. Does anyone know what may be the cause of this?
here is some other observations:
old php version 4 seems to work fine, but ever since around 4.3+ it just won't work from the web.

I'm finding that my server doesn't like to reboot gracefully. Either selecting "graceful server reboot" in WHM or actually typing "reboot" in SSH, which then tells me the server is shutting down. My server is then incommunicato indefinitely until I actually do a hard reset remotely.
Is this common? Is there some way to find out why this is happening?

I just managed to get my subdomains working using:
<VirtualHost *:80>
ServerName sub.domain.com
DocumentRoot "C:/www/apache2/htdocs/dir/sub_dir"
DirectoryIndex index.php index.html index.html index.htm index.shtml
</VirtualHost>
however, I can't use the directories existing in the same folder.
For example, I can't view the 'dir_1' located at /htdocs/dir/sub_dir/ by visiting [url]
Gives a 404.

I got two version of my.cnf, but neither of them works ideally.
On one hand, If i used the old one, the swap memory will be used out after 5-7 days running and system halt.
On the other hand, the second copy of my.cnf will cause too much pain on cpu, even traffic is low, cpu could up to 70 or 80 percentage and hanging there for 1 minutes.
I did a lots optimization in the past (including httpd.conf, my.cnf, sysctl.conf ), and found that the only problem left on my server would be my.cnf, I have to get it right this time!

I have 2 business DSL lines at work with (formally SBC) AT&T. We use a linksys (dual-port, but disabled) and a D-Link router on basic DSL modems.
I run a php script that does a few things in the background that takes roughly 15 - 55 minutes to complete. When I click on the button to open the php script, firefox basically gives the hour glass until it finishes.
The problem is.. ANYWHERE besides our office when I click on the php script it works find. It finishes up in like I said.. 15 - 55 minutes. But for some reason (on any computer in the office.. windows and linux) I get a server time-out message after 12 minutes.
I even hooked up 1 windows machine and 1 linux server directly to the DSL modem (both got their on IP Addresses on different Class-C blocks) and it still times out.
I am curious how to even begin to investigate why it times out at 12 minutes. Do you think this is a specific DSL AT&T problem?
I've had 5 friends of mine try the script and every single one of them was able to run it without any problems. Like I said.. works 100% of the time on my home connection. But once I get into work.. 10-12 minutes... "server time out".. but the server is up.. no problems on the connection.

I woke up to a complaint by the ISP of spamming for one of our servers. More than 10 000 spams in a shared hosting environment. Found Steven online, thank God! PM him and he went to work looking for the culprit. He spend time monitoring and putting in scripts to catch the culprit and in no time found the faulty script causing the spams.
Really saved me a big headache on how to explain to the ISP. Thanks to the consistent excellent work done by Steven of Rack911.
Those unpatched forums of clients can really be a hassle and a big source of problems.

Say i have domain zzzzz.com and have some folders say a, b and c
would ssl if installed for main domain zzzzz.com work for https://zzzzz.com/a and so on ? or would wildcard ssl be required for that ?
And what if that /a folder is actually a subdomain, but since you can access subdomains via url/folder instead of folder.url would ssl work on it using url/folder option instead of subdomain url ?

I am currently running a dev server out of my home. The setup is as follows:
Server is Windows Server 2008.
Apache is running, listening on port 88. On this, I have subversion and TRAC.
IIS is running, listening on default port 80. On this I have an ASP.NET web site that pulls its code from subversion.
Router is a standard Linksys WRT54G.
Router is open as can be, just to test it. Server is in DMZ, all ports are forwarded to its IP (TCP and UDP), etc. This will change, but during setup state, it is what it is.
default.aspx is set up as default document in IIS. Folders are mapped correctly. The file exists in the physical directory it's looking at.
the only site and only Application pool in IIS are for the site in question.
The issue:
Both Apache and IIS work great on my local network.
Both Apache and IIS work great on wireless network.
However, in the wild, WAN works for the apache (port 88) but not IIS. Typing in http://[ip address]:88 or any of the subdirectories works fine. Typing in http://[ip address]/default.aspx returns, in Firefox, "Connection Interrupted -- the connection to the server was reset while the page was loading".
Windows firewall is disabled and unbound from all protocols. As specified, I've opened up the server and router as much as possible temporarily in order to allow me to lock it down again step by step once I have the issue solved.

Does anyone have a problem with volumedrive with accessing your sites?
I have a dedicated server (no load, consumes around 500Mbytes/month) but I my pages open pretty often slow. Today I even cannot open a page because speed is around 1byte/second. Yes, I can access my server, but I cannot wait when a page finishes loading. I wait and wait and wait. Anyone has a similar problem, probably near to me? My ip range: 66.197.221.XX

I am doing my web like this:
1) nginx listening at port 80
2) apache listening at port 78
3) nginx throws all shtml pages to apache
they are working perfectly, except one small thing:
I don't want any public visitor may visit port 78 directly, for now, both:
[url]
[url]
are working for visitors.
Anybody knows how to block/hide port 78 to the public access?
my nginx config snippet:
Code:
location = /index.shtml {
proxy_pass [url]
}
my apache2 config snippet:
Code:
Listen 78
If I make apache as follows:
Code:
Listen 127.0.0.1:78
I will get 502 bad gateway when I visit:

Try following PHP code
<?php echo 2022886285 & -2147483649; ?>
It should return 2022886285
- On my current Web hosting: It works OK.
IXWebhosting.com
Dell PowerEdge 2650
DUAL Intel Xeon 2.8GHz, 512K Cache
RedHat - 7.3 OS on your server
- On my new Dedicated Web hositn: It return just 0. Problem!
HostGator.com
Pentium 4 2.4Ghz
CentOS Enterprise.
Why One simple Bitwise statement doesn't work on CentOS?
New Hosting company support from HostGator tells me
It's code problem or php problem.
However it works on others.
Please test the statement in your site and Reply the result if it returns proper value or not.

Our server count with The Planet only seems to be increasing as of late and I'm now starting to drive myself nuts with bandwidth counts, costs, etc.
My main concern at the moment is our total bandwidth. While we might have a server with a 2500GB limit only use 50% we might have a 1500GB limit use 200%. I understand that any overages are our own fault, etc but there must be a way for us to combine all bandwidth across all servers!
Is it possible for The Planet or any of the other big boys to provide private racks with pooled bandwidth without going colo?

I honestly dont understand why does DELL, HP and others price their 1U TFT monitors at 3 times the cost of the cheapest laptop?
I mean, dont get me wrong, I am all for spending good money to get quality products but I feel very awkward spending 3 times as much for a screen and keyboard when I can get their laptops WITH OS, MEMORY AND HDD for 3 times as less and use it as the 1U TFT monitors.
I can get a powerful server from Dell and HP at that price for crying out loud.
But then again, I might be seriously overlooking something here because what justifies such high price?
