Im just wondering if anyone out there knows of any good books, etc for building webservers from start to finish.
What i want to know is what hardware, what OS is best, etc.
How to configure ports, etc.
My website: downarchive.com - it's wearez site and hosted leaseweb.
Yesterday. My server was downtime to today! We contact leaseweb and they said: "we delete my server" ... when my contract not yet finish.. (8/27/08 it's finish
My database - My source - script - website was delete!
I sundenly!
... Next. I trying contact leaseweb once more time but they didn't take phone !
What's are they doing? I didn't know!
Is there a simple tutorial on how to setup name servers within WHM? We have 4 IP's from the data center and thought to use 2 to run name servers. The scenario is we are moving a few websites over to this box and want to use the same name servers (ns1.domain.com and ns2.domain.com) but have it associated with the 2 new IP addresses. Can someone provide some info?

I've got a Netscreen 5GT firewall.
I've got Dotnetpanel
I've got the SmarterTools bundle
Whats the best way to set this up?
I put DNS, Email, Ticketing, Statistics and Dotnetpanel on Server #1
I put SQL 2005 on Server #2
I put the firewall in front with only 1 public IP
I've directed Port 80, 53, 21, 443 to Server #1 LAN IP
1. What do I do with server #3? How do I host websites with it if it doesn't have a public IP and port 80 is pointed at Server #1?
2. Is it common practice to connect web servers directly to the internet with a public address and no firewall or does everyone forward public ip's through a firewall?
3. I can tie everything into Active Directory;
to setup my nameservers for my vps, it is using lxadmin, and the help is not very good.
I would submit a ticket, but I figure this is something that they should not have to help me with.
So I have setup a dns template, and setup the name servers for this template to ns1.mydomain and ns2.mydomain
But I do not see anywhere to assign ns1.mydomain and ns2.mydomain ips.
Anybody with experience with lxadmin,
I am doing a project with my home servers and I am trying to use dyndns.com for a domain name.
Right now I got srv1.dnsdojo.com and I configured that into my linksys router. Now I got a little confused. Do I configure that domain name into my server?
Note:
I am using it because I got a dynamic IP
i had a problem with setting up DNS in windows VPS server in plesk.
View 0 Replies View RelatedI have two VPS with two different Datacenters. I am running my website on one of the VPS which has Plesk Panel 11.5 installed on it. Since my second server is not in use, I would like to use it as a Secondary DNS Server for redundancy. I know this can be done with Plesk Expand. But, I am not in a position to invest further as I just run 4 domains on my main server. I was looking at installing some free control panel on my secondary VPS and set it up as a Secondary DNS Server if possible. But, I could not find any Guides on setting this up.
How I can do this? I see that we have an option in Plesk - 'Switch DNS Service mode' which can be used to either setup my first server as a Secondary or Primary. I have installed Webmin/Virtualmin on the second server, but how to set this up perfectly. I can reinstall the 2nd Server if required, but not my first one with Plesk.
I have a lot of questions here so if you can't answer them all I understand. even pointing me somewhere where I could get the answers would be appreciated; hardware sites focusing on server hardware, forums focusing on such, etc.
we plan to have three different types of servers:
- db server (self explanatory. mysql. for forums, mysql driven sites.)
- file server (lots of files around ~2-10MB, consistant 70mbps right now, but we want more room for upgrades. needs a LOT of storage room.)
- web server (lots of php files, but also static things like plain html, images, etc. also includes all misc services for the setup-- dns, etc.)
could I be given a rundown for which hardware each of the three should have? I don't need specifics, even just knowing that more ram is important here while cpu doesn't matter as much, or that the fastest disks available are a must, etc would all be valuable info for me. despite that, I certainly wouldn't mind specific hypothetical hardware configs.
for the database server I'm assuming the more ram the better. not entirely sure about the cpu? also not positive on disks...
for the fileserver, how much ram would be practical or useful? disk io will be an issue I'm because plenty of people will be pulling files at once so the disk needs to read from multiple places. scsi (and even raptors) are not an option as we need 750GB+ of space on a reasonable budget. more ram will take some load of of the disks, but how much is neccessary / reasonable?
for the web server I'm assuming cpu first, then ram, but it'll likely need less ram than the db server?
I'm more lost on the disks than anything. scsi on the fileserver is not an option under any circumstances due to $/GB. for the db & web server I'm willing to pay for scsi if the performance increase really does warrant the extra money, but I'd like to be convinced before shelling it out. if you have benchmarks geared at server hardware when it comes to disks I'd really appreciate it.
also, what's the best way to network these together when colocated? each one with a dual gigabit ethernet port and then the communications go to and from the router?
We send mail to another servers but we cant recieve mails another servers. We can't recieve with webmail and outlook.
I look logs but there is no error and our ip is not in blacklist.

I was wondering if it is possible to cluster 2 web servers and 2 mysql servers with only one server working as load balancer.
I am planning to use LVS (ldirectord and heartbeat).
Let's say I have 3 IPs allocated to the load balancing server.
111.222.111.222 (Main IP)
111.222.111.223 (Web Load Balancing IP)
111.222.111.224 (MySQL Load Balancing IP)
If a connection is made to .223 it would pass the request to one of the web nodes.
If a connection is made to .224 it would pass the request to one of the MySQL nodes.
Is it possible to do this?
If not, can I run, for example, nginx on 223 IP address to provide forward proxy? (Then it would not be able to HA but the main point is to load balance so)
Also, what would be the best way to keep the data same on both web servers? This is a web cluster for a very high traffic forum with a lot of uploads every hour so it has to do real time synchronization. I heard that DRDB is only one way and not two way so I'm not going to be able to use this.
I am just colocating servers and managing them myself, and renting services off of them. In the future I would like to start offering dedicated servers as well. I am wondering if many companies do this, or if its more of a general practice to just setup as a reseller? The worst part that comes to mind is thinking of how to do billing for the bandwidth per month. With my setup I would only be offering flat bandwidth packages (like 2TB a month) but even so, I cant think of anyway to automate it so WHMCS knows if they went over, if so, how much, etc.
View 6 Replies View RelatedRecently left a big corporate job and started my own consulting firm in the area of human resources/employee benefits. Right now, my technology consists of a laptop with online backup through Carbonite. I am ILLITERATE when it comes to technology, so bear with me please....
BackgroundThe business plan calls for growth by adding a small number of employees, starting with an assistant, along with working with independent contractors. These will each need to have access to the files that now reside on my hard drive. I don't anticipate more than 6 people (employees and/or contractors, combined) in the first year.
In addition to the shared access described above, I would need to be sure that the environment where files are stored is highly secure, and that I can grant access to files to some people and not others.
In addition to the above, I need to ensure that all the data are backed up routinely.
Employees/contractors will likely not be in the same office location where I am located, and some (most) may work from a home office.
My assistant, when hired, may/may not be in my office. Regardless, (s)he will need to have access to (and make changes to) my contacts and calendar in outlook. In addition, (s)he will need to be able to read and send emails on my behalf.
AT&T, as part of my advertising with them in the Yellow Pages, is developing (and will host) my website. Included in their service will be email boxes (up to 20) with my domain name.

Based on these points, I figured I needed to buy a server, so I've been talking with Dell. Of course, they'll sell me a server and they have a relationship with All Covered who will install it and make sure its operational.
But after talking wtih Dell, I learned that there was something called managed hosting, colocated hosting, dedicated hosting, and shared hosting. I called Rackspace, they said they would be overkill for what I needed and referred me to Mosso. Mosso said the same thing, and sent me to this site.

View 14 Replies View RelatedWhile i have loads a experience running servers remotely, I know to start my own ISP is a bit more costly and involves things like rack servers, temperature controled rooms and BANDWIDTH.
I have handle on 1st two, ( and yes htings like insurance and a store are looked after )
What i need are a list of T3 providers that I can contact about purchasing a dedicated T3 line for our store. While the location isn't yet set in stone and i may in fact look at a existing computer store owner who may be open to the idea already.
The company will host local websites, and others websites.
AND allow for reselling on a lessor level and include at least 6 others who host game servers.
With these 6 the T3 line will probably be almost half used, so the ISP must be scalable for growth.
The thing i need in nut shell are pricing on a T3 line of my own in or close to downtown Oshawa Ontario, Canada

we have a vps server and someone did what I would call a calling card attack, thankfully.
It is a stock kubuntu os with stock apache. Root passwords for everything have been changed to our own
Somehow they logged into kubuntu as root and changed the htpasswd in usr/passwords (changed to protect the password).
Then since they changed the htpasswd they were able to log into phpmyadmin and changed the admin password in the database.
I'm pretty sure I know who did it and he is teaching us a lesson which I respect but he will not comunicate with us.
We have hourly snapshots of our vps and we need to know how they are getting in. See my sig and click on the hotspot login.
Looking at the sudoers there is the Defaults line that we suspect as a means to get in.
We have a great php etc... app but it is either Apache or kubuntu that they can get in.
I would like to learn about what needs to be done about security but where do I start?
Can someone help me look for something that would allow the attack?
I'm a php guy and it is not a mysql injection attack nor is it an xss attack.
I am not a kubuntu / server security guy and now need your advice.

I have a VPS server, i installed and configure csf, but wonder if i reboot my server the csf would close the connection, or wont work...
so i remmeber how but i really forget and cannot remmber how to enable the csf on the vps start up..
I spent all my afternoon on this but I couldn't managed to solve this problem out. Hope someone knows the solution for this one.
I've chrooted Apache and now it won't start. I try to run it with chroot /chroot/httpd httpd and it doesn't start but instead enters a single error in a error log. Something about permission being denied and apr_proc_detach constant. The best part is that I managed to run it flawlessly on an another server, but on this one it won't start. If I start it with -X parameter then it runs fine. Has anyone came across this error before? What libraries I should put in chroot environment to avoid the apr_proc_detach permission denied error?
On another computer it runs without problems, so I believe it's problem me not including all the necessary libraries in the environment (I included everything on the ldd /usr/sbin/httpd list).
I have installed CSF on my VPS and when I try and start it I get, anyone know what going on and how to fix it, or pass info on to my host.
