Apr 10, 2007I was wondering what the general opinion of both administrators and end-users was about either SLM or UBC (Virtuozzo memory management methods)?

Virtuozzo Or In-House VPS Management Software
May 20, 2008Let's say someone is on the final step of setting up VPS hosting service. There are 2 options.
1. To launch Virtuozzo based VPS hosting
2. To develop own VPs management software
I would ask you to tell me 2 things. What would you do, would you spend a month or 2 in developing VPS control panel or you'd start with Virtuozzo.
The other question is can you please post information about Virtuozzo pricing and dealers. The guys from Parallels didn't respond to email send before 48 hours. I'll give them a call but still want to know what do you think?
Memory Management On VPS
Jul 27, 20071-On a VPS if I have 128 RAM guaranteed and 512 Burst, when I do top I can see the 471856k, it means at that moment I can use 471856k RAM, or this memory show is something I cant trust?
2- If I have 128 guaranteed and for some reason a a process tries to eat more than that(like 1 gig for exaple) it will be not allowed? Do I have to pay anything for that leak? DO the leak affects the ENtire host?
I believe I kno all those answer but is better to double check them....
Understanding Linux Memory Management
Jan 20, 2008I've been working with Linux lately and been wondering how Linux (Fedora/CentOS) manages its memory usage efficiency.
What I've been noticing is, Linux uses quite a lot of memory for just a single application. For example, Firefox-bin uses like around 100mb of memory.
At the same time around, when KDE/Desktop Environment aren't installed, Linux uses very small memory for non-GUI applications, such as those of hosting-related services.
Isn't using 100mb of memory for a browser application a bit too much? Is the memory information under "top" command represents the physical memory available? Is there any difference in performance when in physical server compared to virtual server (virtuozzo for example)?
Yet Another Topic About Process/memory Management
Oct 23, 2007Yet another topic about process/memory management : )
I have a 256 RAM VPS and I need to free up more memory, Im using cpanel and when i use the "top" command, those are the major memory consumers!
PS.: I removed some of the list cause I know i really need them
21635 root 16 0 20888 10m 1316 S 0 1.0 0:01.73 cpsrvd-ssl

18140 mailnull 20 0 7404 1140 752 S 0 0.1 0:00.00 exim
So, my basic question is, which of them I donīt need? SOme of them I know what is it but still have some questions...
1-cpsrvd-ssl , i know this means someone(me) is connected to cpanel, but even if I log out the process stills there, is that normal ?
2-authProg , sometimes there are a lot of those process running, what is that? is that normal ?
3-exim, 3 process running, is that normal ? exim is better than sendmail ?
4-After those questions, which process am I able to drop(and how?) - I only need email forwarding(that is already working), smtp, mysql(already working too), and tomcat server.
Cpanel VPS - Plenty Of Free Memory, But 'committed' Memory Exceeds VPS RAM
Jun 12, 2009I have a VPS. And have had an issue both when it was 1Gig and now I recently downgraded it to 768m, because I am moving some sites to a dedicated.
However, the part I am having trouble grasping is that when I look at graphs from Munin, it will typically always show 200-400MB free memory (and free -m and top agrees with munin), but Munin shows 'committed' memory that is above the total Ram on the VPS and once the 'committed' ram exceeds the VPS limit, processes start failing.
So, why is 'committed' memory exceeding the RAM on my VPS, when Munin, free -m and top all show there is free memory available?
Code:
root@server [~]# free -m
total used free shared buffers cached
Mem: 768 449 318 0 0 0
-/+ buffers/cache: 449 318
Swap: 0 0 0
Here's a graph that munin produces that shows the 'committed' memory exceeding the total memory.

Memory Usage :: Put More Content Into Memory?
Jul 16, 2009I just got a new server Dual E5520 with 6GB RAM, SAS 15k rpm raid10. It's running well. However, the memory usage is just around 2.5GB, even when I have more traffic. Here is the kernel info
Quote:
# uname -a
Linux server2.[url]2.6.18-128.1.10.el5 #1 SMP Thu May 7 10:35:59 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
Any idea that we can put more content into memory?
I'm Missing 7 GB Of Ram: Installed Physical Memory 8 GB / Total Physical Memory 1 GB
Apr 4, 2009I just ordered a server from serverbeach that should have come with 2 GB but I see that this one comes with 8 GB
Unfortunately, I seem to be missing 7 GB of ram.
Installed Physical Memory: 8 GB
Total Physical Memory: 1 GB
Windows 2008 Server Web 32-bit
Now, being a 32-bit system, I should see 3-4 GB of ram right?
Any idea why only 1 GB is available for the OS?

512MB Memory VPS... Out Of Memory Already
Oct 1, 2009I have a 512mb DV server with Mediatemple, which I am running 24 (ish) domains off (most of them static websites) and a teamspeak server. I would say MAX theres 10 users online at a time)
Now, I know its running out of memory because i get frequent QoS Alerts in plesk (kmemsize is apparently the memory size):
Oct 01, 2009 11:52:57 AMBlack zonekmemsize
I have attached my results (when I did top).
My questions are:
1. Should I be expecting to be out of memory running what I am?
2. Is there a way to see the problem domains (memory wise)?
3. Are there any ways I can reduce the memory? (I have followed this already:
[url]
4. Where is the memory usage coming from (I am finding it very hard to understand TOP)
OS (VPS) Management
Oct 25, 2008I recently got my hands on a few unmanaged VPS to play around with and learn how to work on them (eventually plan on going dedicated, so this is a preparation for that). I know the basics of working on Linux via command line, but beyond that I'm clueless. Does anyone know of any good guides for setting up and managing a LAMP environment on a VPS?
I'm mostly interested in CentOS and Debian.
I can find guides specifically for 1 or 2 things, but so far the only useful (complete) guide I've found is the one here. I'm not sure if that's still up to date on todays standards as it was written 2 years ago?
Things I'm looking for:
- Installing and setting up a LAMP environment
- Jailing SSH
- User/Group management
- Firewall setup / security hardening (I've read the thread in VPS tutorials as well as the one in Technical and Security Tutorials about securing your hosting company)
2 more questions...
1) Wondering what would be better... webmin or ispconfig? From what I understand webmin is more OS oriented and allows easy configuration of various parts of the OS while ispconfig is more hosting oriented? I take it running both at the same time is not recommended/needed?
2) Still not entirely sure what OS to choose. In my VPS atm I have the following available (along with the likes of Ubuntu, Gentoo and SuSE but I think the list bellow is what I should use). Would love if someone could list some advantages/disadvantages of each.
- centos-5-i386-afull
- centos-5-i386-hostinabox571
- debian-3.1-i386-minimal
- debian-4.0-i386-minimal
Appreciate any input.
Thanks for reading.

WHM Management
Oct 8, 2007How do i go about setting up a DNS zone using WHM for my new dedicated server? Also, what does record type mean (as in: A, A6, AAAA, CNAME, MX, NS, PTR, TXT, WRK)?
If someone can point me to a good tutorial or reference so that i can get my server up and running with multiple domains, I'd appreciate it.
DNS Management
Sep 6, 2007We run around 300 domains for our clients; in the past we've believed that it was better to outsource DNS hosting, we've used a few different local companies but now we're getting to the stage that I'd like to consolidate all the records to one company.
Does anyone have any reccomendations for ultra reliable, easy to manage? Or is it better to put a dedicated machine in and run our own service?
I've got a few domains with Zoneedit, but I want to way-up some alternatives, I don't think the zoneedit admin is particularly user friendly and it's quite expensive $1000+ a year for what we need.

DNS Server And DNS Management
Jan 10, 2009i have few dedi servers from one Us company, i am currently using their DNS service, we are into small level hosting, i want to run my own DNS, is it necessary to run a separate server for DNS?
Actually how the hosting companies do the name server pointing, for an example if i am buying a server and want to host a few domains in that server, what normally we do is we will change the name server to that companies name server
ns1.domain.com
ns2.domain.com
my question is if i am pointing my domains name server to the name server
ns1.companydomain.com
ns2.companydomain.com
how that company points the domain to my server for an example its ip is 72.xx.52.xx i am bit confused in this.
Also i have a doubt how they are creating this for n number of domains?
DMZ Server Management & PCI
Sep 14, 2009We are working on our pci certification ( fun times right? ) and i was wondering what other people do for server management in the dmz. Few things we are looking at listed below. We will be doing cisco zbfw for firewalling and using NAT.
#1
Servers have 2 nics, 2 ips, gateway ect. One of the networks would be considered a "management vlan/network". Other network would be for all other traffic, including natting to the internet, and traffic to the "internal" zone but locking down traffic to source,destination, and protocol level.
On windows you really on have 1 true default gateway, and because windows doesnt just send traffic out the interface it came in, but looks at the routing table, some network routing issues popped up.
#2
Use only 1 nic/vlan/ip/gateway. Lock down traffic to source,destination, and protocol level for dmz to "internal" traffic and do an "inspect" statement to allow all necessary traffic back in and drop everything else. "Internal" to dmz would just be an inspect all because this traffic wouldnt need to be firewalled so management traffic would work just fine.
SSH Management Software
Nov 3, 2009Does anyone know of any software applications available of which would allow staff/employees to log into SSH while actively logging all input and prohibiting certain commands from being run?
A list of applicable servers to log into would be amazing as well, although that might be reaching too far.
IP Management In DirectAdmin
Dec 12, 2008I have 4 ip addresses.
74.63.67.146 - my main server. I have also configured my main domain to "own" this IP address and have installed an SSL cert. The domain and the cert work correctly but when you type in the IP address in, it shows "Apache is functioning normally".
74.63.67.147 - this is owned by a client. Same thing happens as above except that the domain name and the IP address point to the Apache message.
74.63.67.148 - this is the shared IP. Everything works correctly.
74.63.67.149 - this is another owned IP and it works correctly.
The only thing that is different from 146, 147
Best Remote Management
Oct 26, 2008I just want to know what is the best way to run a hosting solution remotely. I.E have OS re-installed without having someone to do this for us in the DC for example?
I've heard KVM over IP but unsure to where that would lead us.
OS Management For Colocation
Apr 3, 2008Anyone know of any service that will provide 24/7 support for colocation servers I own?
By support I mean regular system updates, monitoring server stability, and be available 24/7 if problems were to occur.
I plan to colo with steadfast networks.

Nov 29, 2007file/folder management system where I can upload files thought the system of FTP program and setup accounts that can access that folder with various permissions.
The goal is to be able to create any amount of folders and sub folders and assign unlimited amount of users to individual folders with permissions to upload (with or without over-right privileges), and download files in the folder they have access to.
I am open to using a third party, if Yahoo! or some similar file hosting company offers such a service.

Which Content Management System (CMS)
Feb 24, 2009I wondered which Content Management System (CMS) is the best for a website? I read that there are many to choose from, examples are Wordpress, Drupal, Joomla etc. Which CMS is more SEO Optimised?
Th website I will be setting up will be of the same genre as the following website startutor.sg. Therefore, I am wondering what CMS to use.
I thought of designing the website using AI or PSD and asked someone to code them (not sure of the terminology used) for me as I don't know anything about CSS, HTML etc.
