Limits.conf
Apr 17, 2007I would like to set some hard limits for some developmental testing I am doing using quota tools and what not. In limits.conf I have the following:
--------
@dev hard cpu 0.30
--------
As far as I can see, this would limit all users in the group "dev" from using more than half a minute of CPU time, am I correct?
Assuming I am, once I write these changes no limits seem to be enforced. Are these values cached in the memory and a reboot is needed for them to take effect?

VPS HARD Limits? (hardware Limits, Such As CPU/memory)
Apr 11, 2009I have been playing around with different virtualization platforms:
- OpenVZ (newer kernels do not support hard-cpu limits for whatever reason)
- Xen Server
- Windows Hyper-V
- Linux KVM
However, none of them seem to be able to stablish HARD limits on resources for a virtual machine. Or am I missing something?
HyperVM supposedly has hard-limits because they use OpenVZ older kernels, right? -- I have not tried Parallels Containers do they have hard-limits enforced?
DNS Issues Rndc.conf & Named.conf
Apr 8, 2009It started with this error:
Bind reloading on server01 using rndc zone: [ns1.mydomain.net]
Error reloading bind on server01: rndc: connect failed: 127.0.0.1#953: connection refused
so i did the obvious checked the csf firewall to see if port 953 was enabled and it was
so i took a look at rndc.conf
Code:
root@server01 [~]# nano /etc/rndc.conf
#start of rndc.conf
key "rndc-key" {
algorithm hmac-md5;
secret "KLGSBmWZrev0I4fR4Tm4GXxdcYSTFzF23b1f9is1M=";
};
options {
default-key "rndc-key";
default-server 127.0.0.1;
default-port 953;
};
# End of rndc.conf
# Use with the following in named.conf, adjusting the allow list as needed:
#key "rndc-key" {
# algorithm hmac-md5;
# secret "KLGSBmWZrev0I4fR4Tm4GXxdcYSTFzF23b1f9is1M=";
#};
#
# controls {
# inet 127.0.0.1 port 953
# allow { 127.0.0.1; } keys { "rndc-key"; };
# };
# End of named.conf
Then i took a look at named.conf
Code:
options {
/* make named use port 53 for the source of all queries, to allow
* firewalls to block all ports except 53:
*/
//query-source port 53;
/* We no longer enable this by default as the dns posion exploit
has forced many providers to open up their firewalls a bit */
// Put files that named is allowed to write in the data/ directory:
directory "/var/named"; // the default
pid-file "/var/run/named/named.pid";
dump-file "data/cache_dump.db";
statistics-file "data/named_stats.txt";
/* memstatistics-file "data/named_mem_stats.txt"; */
};
logging {
/* If you want to enable debugging, eg. using the 'rndc trace' command,
* named will try to write the 'named.run' file in the $directory (/var/named").
* By default, SELinux policy does not allow named to modify the /var/named" directory,
* so put the default debug log file in data/ :
*/
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
// All BIND 9 zones are in a "view", which allow different zones to be served
// to different types of client addresses, and for options to be set for groups
// of zones.
//
// By default, if named.conf contains no "view" clauses, all zones are in the
// "default" view, which matches all clients.
//
// If named.conf contains any "view" clause, then all zones MUST be in a view;
// so it is recommended to start off using views to avoid having to restructure
// your configuration files in the future.
view "localhost_resolver" {
/* This view sets up named to be a localhost resolver ( caching only nameserver ).
* If all you want is a caching-only nameserver, then you need only define this view:
*/
match-clients { 127.0.0.0/24; };
match-destinations { localhost; };
recursion yes;
zone "." IN {
type hint;
file "/var/named/named.ca";
};
/* these are zones that contain definitions for all the localhost
* names and addresses, as recommended in RFC1912 - these names should
* ONLY be served to localhost clients:
*/
include "/var/named/named.rfc1912.zones";
};

Email Limits Per Hour
Apr 18, 2009I have take some weeks ago a VPS with 40 giga space and 386mb dedicated ram and all is managed with WHM/Cpanel. I need to know how I must set the limit of sending email per hours...In fact I see all hosting company limit that to more less 500 email per hour. I know this limit depend of lot factor like number of account on server and activity or users...
I ask that because my users will have Joomla installed with a Newletter component and so something this component will be used for send monthly newletter...
Do you have some experience with that ? How have you set your email limit? How much users have you on your server?
Other question: If for example I set limit to 500 email per hours and a user send 1000 email...what happend to the 500 other email? It will be put on queue and send the next hours or it will be lost?

ServerAlias Limits - Many Domains
Jan 1, 2007Not sure of this is the correct forum ,buthere goes.
We're trying to set up a virtual host with many (50+) domains. In the past I've been successful with 20+ domains within the same ServerAlias directive, but on researching this, I'm seeing different answers. We're running Apache 1.3.33.
Some places suggest putting all domains in one ServerAlias line (which of course gets doubled by adding the wild card *.domain.com)
Others say there is a limit and that the solution is to have multiple ServerAlias lines within the same virtual host directive.
I have looked at the apache.org docs and they don't address this question as to line length or multiple ServerAlias lines.
The docs do indicate that wild cards are acceptable (and that would help in my situation), but normal wild card usage in these situations is for subdomains, i.e., "domain.com *.domain.com"
I would need to use "domain*.com *.domain*.com"
Would anyone know if the latter use is permissible for wild cards in the ServerAlias directive, and especially if one may use two wild cards in the same alias, i.e. *.domain*.com?
How Much Can You Push Power Limits
Dec 28, 2007We just moved to a new colo facility, and we also added some additional servers as part of the move. Our cabinet has 2x 20amps power, which is fed into 2 APC AP7930 PDUs. The PDUs have printed on them a 16a limit, though from looking around the datacenter, I see some people are doing 17a on the same PDU with the same power feed.
How much can you realistically push the limit? Currently we're at 13a on each PDU, but there are still more servers to be powered up. Does the PDU shut down altogether for an overload, or can you have it just power down some ports automatically?
Windows Server 2008 - CPU Limits
Oct 28, 2009I'm planning on getting Windows Server 2008 Standard edition, but getting confused on the listings.
Some listings display (1-4 CPU), while others dont have anything in that regards.
So my question is for anyone who has purchased Windows Server 2008 Standard -
Is there a CPU LIMIT?
If so is this for physical # of CPU's?
And will this factor in QuadCores as 4 CPUs?
Setting CPanel Backup Limits

Web Host With No Limits On Sending Email
Dec 31, 2008I currently have a shared hosting provider which I am happy with but I have come across the need to exceed their email sending limits (which is 20 emails per minute).
I am planning to run a one-day (might even be one-hour) online contest where my customers would fill out an online form where a php script inserts the form contents into a database and then sends a confirmation email to both my customer and two additional email addresses (Me and a partner).
I am expecting up to 100 forms a minute to be submitted (which would translate to 300 emails) so I am looking for a reliable solution to do this without spending more than $20/month. "Throttling" the emails is not an option as delivery is time-crucial.
Are there solutions out there that would handle this kind of scenario? Or perhaps solutions where I can keep my existing provider and use the new one just for scenarios such as this?
Tired Of Fake Storage Limits
Aug 8, 2008When will that beautiful day come when web hosting companies stop to put up fake storage limits? I am so surprised that all of these actions are legal, and if they aren't legal then I don't understand why there isn't move governance over these things.
I mean, you have a nice and popular company like Media Temple, yet you glance at their usage policy and see this:
Customer may not use hosting account as a remote storage server only. 75% of customer's content files stored on Provider's server must have associated HTML, or PHP files inside the account linking to the content stored on that account.
What is that all about? What kind of legal website would actually use 75GB of storage.
Why doesn't their 100GB limit package have a cheezy star beside it that clearly says "hey, actually you only get 25GB of storage, the rest is just BS and we'll never actually let you use it". What if you buy a can of paint and they say "well, you cannot use this paint for your house, you may only use 25% of it on your house and the rest on your fence". Yea, sounds like a great deal, now I have to buy 4X more paint.
And to counter-act that usage policy, what if I just have an PHP page that is a dynamic directory listing? Isn't that, in essence, a PHP page to which all of the directory content is associated?
Aside from all that, yes I understand the marketing value of big numbers and giving people 100's and 1000's of GB of supposed storage – but how in the hell is that legal?
These companies are charging people for something that is unattainable. Because in 99% of the cases, if you actually use all your disk space, your account will be terminated without notice for some BS reason or because you are using too many processor resources.
Well if you KNOW that using 100GB of disk space will use too many other server resources, why are you selling that quantity of space? Again, it's not actually being sold, it's an illusion, and I absolutely don't understand how it's legal.
Another example would be like, selling a car that can go 500 KM/h but really by the time you reach 400 KM/h you are already out of gas, so you'll never really get to 500 KM/h.
Can they really advertise the car as having a top speed of 500 KM/h? Come on...
Oh and I am not a bitter customer of Media Temple or any other overselling web hosting service, it's just a trend that has been on the rise for some years now and it's really bugging me that somehow all these lies are legal. Next up is "unlimited" web hosting, except you are limited by everything except storage... so yea, not really unlimited. Again... legal?

Plesk 11.x / Linux :: How To Get Mailbox Limits From Database
May 21, 2014I have a script which checks the mailboxes of all clients to notify them when they're reaching capacity.
This does so by checking the psa database for their set limit and matching that to the maildirsize file within the user's Maildir directory.
After upgrading, though, my SQL query no longer works - it was:
Code:
SELECT clients.email as owner_email, domains.id, domains.name, Limits.value AS domain_quota, mail.mail_name, mail.mbox_quota from Limits, clients, domains, mail WHERE mail.postbox='true' AND limit_name = 'mbox_quota' AND domains.limits_id = Limits.id AND mail.dom_id = domains.id AND clients.id = domains.cl_id ORDER BY domains.name ASC
However, on closer inspection, all values in the domains table for limit_id are NULL.
Has this changed in 11.5? Is there an alternative way to quickly get all limits for domains?
