Skill Level Required For Root Server Management
Jun 30, 2008
I am hosting about 12 TYPO3 websites in a shared hosting environment, but I need to think about upgrading to a faster (dedicated) server as some of the sites have a higher traffic volume.
I am not a pro and use Linux only as a user. How dificult is it to manage a root server? Is all done via an easy Control Panel or do I need expert knowledge to install software etc?
Or shoud I look for a managed server where all is done for me?

Now..I am logged in root in two terminals and it shows
root pts/2 Apr 28 15:19 (x.x.x.x)
root pts/3 Apr 28 14:06 (x.x.x.x)
I am just wondering how can the root perform ftp tasks where my root login is sitting idle and what about pts/0 and pts/1
I stopped the ftp service in cpanel and it is started automatically..

Due to problems with our current hosting company we are desperate to move our site to a dedicated server.
I am a UK based company with a .co.uk website.
Can anyone recommend a company?
How long does the change over take?
How much down time can I expect during the change over period?

Does anyone have any recommendations for a company that could provide a reasonably priced, reliable, unmanaged server for me somewhere in western europe?
I'll need a reasonable amount of bandwidth, so this is a consideration.
I'm based in the UK, but willing to look at other, more digitally enlightened countries nearby (Norway, Finland, France, Germany, etc) to get a better price since servers are very expensive here.
The server be hosting a big AJAX application so latency is a consideration also.

I've been carrying some weird hours lately, so I'm able to see activity on my sites that I normally don't see.
Certain IPs are trying to diddle their things into my server and need the boot. It's not consistent (ie not happening every 5, 10 mins)... it's periodically throughout the months. I'll see an IP I blocked 2 months ago just randomly show up at 4:30am and try accessing the same files it was probing during it's last visit. Assuming this is just some sort of bot, can I block it permanently?
I know APF has a collection system that purges an IP list to keep it from bloating, and I had PSM do some hardening so I'm not entirely sure about the workings of APF firewall. So far my IP blocks are blank (which is a good sign!), but I'd like to add some nuisances to it, to keep their crap from appearing in my error logs anymore as "Denied by Server Configuration"
My question is: Can I block people at server level permanently? I do not want their IP being taken out with the purge list that comes by every so often.

I have a few boxes on a special setup in a rack that I want to monitor bandwidth usage on for a while. There really isn't a way at the moment to do it switch level. Some of the servers have cPanel, some are just straight Linux (CentOS). I have seen where you can setup iptables to measure/monitor bandwidth, any other easy and effective suggestions for doing this?

i 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?

We 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.

Rather than just tagging the subject with ***SPAM***. Am I going to have to recompile spam assassin in order to get that working? I have a client of mine who wants all spam just removed before it hits his inbox. Is there a setting somewhere in cpanel that I am missing for this? Possible just to apply it to one domain name?

If you are deploying PHP and MySQL along with a site/application, how do you do it? Do you work with the individual components, or do you lean towards ready-made packages?
I use WAMP to develop my applications, and I find it a very simple yet powerful tool for deploying Apache, MySQL and PHP to Windows platforms. I've been looking at the Zend Server today too, which strikes me as very interesting, especially the full version.

I'm not talking about weak sauce companies that treat your server like any other server and apply settings base a file they got saved on their desktop.

Maybe I'm underestimating the importance of server management, but I can't see how it is worth it to pay $300 per month for a server that can be built for $700 with the co-location costing about $100 per month.
So, I'm thinking that I can build a server or just buy a server that was considered excellent 2 years ago off of Ebay for about $700 or maybe less. From there, I simply need to find a $100 per month co-location hosting place and a freelance server dude to keep the thing updated for me and work out problems if they actually come up.
So with that said, where is a good place to find a freelance server manager?

I am planning to implement a chat software for our team.
We are currently using AIM. But, we have planned to install any software which works like AIM but it should be controlled by us.
Only, we can add or remove users. Only, we can see the chats done. To be frank, I need a software like AIM installed on a server which should be controlled by me.

I initially posted a topic to get help with a problem because I want to fix it myself without wasting the time of the server management company. They however picked up the post and said I should opened a ticket with them.
The problem is however still not resolved to my satifaction after a few days because we differ on some points so can you please air your view on this matter?
-----------------
[url]or [url]
Problem 1) Certificate error that hostname and certificate name don't match.
Problem 2) At some places in WHM or cPanel there is a secure and non secure warning items.
The problem 2 is perhaps to bug in WHM V11 so it is not so important.
However, the server mangement staff insist that problem 1 is because the login is via IP (or other domain name) and not via hostname but I don't agree with them because.
a) During the years I always logged into whm or cpanel via ip or domain names and never got such error.
b) cPanel redirect any whm or cpanel access to the ssl ports under HOSTNAME so it MUST match the certificate even if you use 75.127.69.82:2087
I don't get any error if log in with [url]so it is clear that the redirection to ssl ports under HOSTNAME like above don't work correctly.
That the redirection works can be seen by using [url]because the same error comes up (for mercury.domain.com) despite the site have his own certificate.
What we have here is.
Hostname = mercury.domain.com
Certificate Name = mercury.domain.com
[url] (Works Fine because certificate name is mercury.domain.com)
[url] (Name of site don't match mercury.domain.com despite redirection to hostname IN WHM)
[url](Works fine, Host name = othersite.com and match certificate name)
[url](Name of site don't match mercury.domain.com despite redirection to hostname IN WHM)
What I suspect is that cpanel redirect but NOT to the actual hostname (mercury.domain.com) or otherwise present/display the hostname incorrectly so that it don't match the certificate.
WHM 11 setting: Redirect to ssl ports = enabled
Two further settings, redirect to hostname = enabled
(None of the settings have any effect anyway and I tested hostname, certificate name and origin domain name redirect with the same results)

One of my sites has outgrown its current cheap hosting so I'm looking to upgrade. I'll probably just snag a low end, leased server from EV1 unless someone has any better ideas.
I've attempted to use a unmanaged EV1 server in the past without any setup and it was a disaster. So this time I want to pay a guy/girl to set it up properly.
My needs are not that great. I just need a server that can handle a vBulletin forum, and your typical database driven article site. At the moment, I'm only getting about 2,000 uniques per day, but the site has been growing at a constant rate.
I'm writing a new script that I think will double the sites bandwidth usage by early summer so I think I may be able to justify the expense of going from a $60 per year server to $100 per month server.

Does anyone here have any experience outsourcing server management? I've setup and run my own Linux server and configured my own database and PHP and Apache but I just don't have the time to keep everything running, backed-up and updated.
I'd love to have someone who I could just send jobs to, such as upgrading to PHP 5.2.2 or figuring out why Postgres doesn't start up correctly or why the logs aren't getting rotated automatically anymore or making sure the backups are happening or recovering from a hard disk failure, etc. I'm sure I could figure all this out (maybe on the second or third tries too), but I just don't have the time or the expertise these days.

After doing the proper research, I decided to lease a dedicated server from WiredTree. Let me start by saying that in the short time that I've been a customer of WiredTree.. I have absolutely loved their service! After one month, I will do a full review of their service.. because they have been absolutely amazing!
The only issue that I've had up until now is not their fault at all. When we first signed up to their service, they were aware that we were getting a dedicated server with them because of their proactive support with DDOS attacks. Sure enough.. first day up.. we were getting DDOSed.
WiredTree responded very quickly, and worked for endless hours to help us out. The issue was resolved, and the site ran great for about another week..
Then, DDOS attacks started up again and the site became very slow. Not only was Apache running slowly, but FTP/Shell would load very slowly. I asked them to assist me with the DDOS, and they did.
Now I'm just not sure of what the issue may be, because the site still loads slowly or times out for many of my members. The site loads fine for me (now), but was lagging/timing out up to this morning. - Once again, I'll note that up to now, WiredTree have been as helpful as they can possibly can.. though for them, the site has loaded in under 3 seconds the entire time. They've asked me to submit affected IPs.. and I've submitted one that I know is affected. I'm waiting to see if the IP was blocked.. though its only loading slow for them. It is not blocking them, so I'm pretty sure that they weren't hit by the firewall.
My question is.. does anyone think that PlatinumServerManagement could more for us as far as finding/resolving an issue here? Perhaps a fresh pair of eyes could help considerably..
My concern would be having two people managing the server. Obviously PSM won't do anything unless I create a ticket, requesting their help.. but would having PSM work alongside them possibly become intrusive for WiredTree?
I'm just looking for some advice on the next step. If it'd help at all.. I could post the URL so I could see if other people experience the issue.

I got around 5 servers running and added one more last week. Its becoming a pain managing them all. Updating, setting up new policies and restrictions, securing or whatever other tasks that are needs to be executed on ALL these servers.
Wanted to know how you guys are doing it. I know that some hosts use HSPc, HSphere, Helm, etc to manage the entire cluster. But what about the lot who use cPanel?
