I have been trying to setup SPF records for all of our hosting servers but need some assistance.
Lets say we have three servers with the following RDNS:
ns1.server.com
ns2.server.com
ns3.server.com
Would we create one SPF for server.com and add it to the DNS zones on each server?
Or should we create a separate SPF for each server?
Right, I have my email address (say email@domain.co.uk) connected to my DirectAdmin controlled server.
I have an the simple email services provided by 1and1 that I haven't used for ages.
I am a bit confused how multiple MX records can be used, so far I have edited my DNS record file for domain.com to look like this:
Code:
domain.co.uk.14400INMX5mx00.1and1.co.uk.
domain.co.uk.14400INMX10mx01.1and1.co.uk.
domain.co.uk.14400INMX0domain.co.uk.
If im not mistaken the above show the email server domain.co.uk is connected to (domain.co.uk) is the primary server, with 1and1 2nd and 3rd.
However if I changed the priorities all to the same value, i.e "0" would that mean the mail is delivered to all?
My ideal solution would be, if the primary server was down, send mail to secondary, but that leads me to another problem. When I want to check mail with Thunderbird its connected to imap.domain.co.uk and not imap.1and1.co.uk, so the problem now is mail split over two servers....! I would like a redundant system, to ensure email is online 99.999% of the time.
So my question is, what are peoples current solutions with multiple MX records, and how have they achieved 99.999% uptime of emails.
I have had multiple A records for a website for years, i.e.
www.mywebsite.com => 1.1.1.1, 2.2.2.2
Well 2.2.2.2 has been down for a few days due to technical issue. So I just figured "well i got some work to do this weekend to bring it up, no rush". Turns out that customers are calling and complaining "I couldnt reach your website yesterday for a few hours".
I am seeing no problems personally, but some customers are. I dont think the percentage of customers is very high but there are so far a dozen or so complaints.
Any ideas on what I am doing wrong or where to start looking? I thought the major browsers (i confirmed with four clients they are using IE) would try 1.1.1.1 and then 2.2.2.2 or vice-versa. But apparently that is not happening. I dont think the TTL makes a difference.
What could be set up wrong or is this to be expected ? (and how to improve for future?)
I've run into a problem with my Plesk install with Amazon Route 53. I have the latest extension installed (version 1.2 release 2) on Parallels Plesk v12.0.18_build1200140811.16 os_CentOS 7.
The extension has been working perfectly well for me for months. I was adding new domains to Plesk and discovered that as I was making changes to DNS records that a new zone file was created on Route 53 instead of updating the original one.
I did notice that this started happening when I surpassed the 100 domain limit and seems to only happen on domains created at #101 and on. (in other words, I can edit a domain that was created before I got to domain #100 [ie domain #1] and it does not create a duplicate zone file).
I turned on debug mode for plesk and am seeing the json calls with the correct commands coming through.
Redacted sample of an update of Domain #104
[2015-06-10 16:42:43] INFO [panel] The domain alias <b>mydomain.test</b> was created.
[2015-06-10 16:42:43] DEBUG [util_exec] [5578bd6355bc3] Starting: dnsmng /usr/local/psa/admin/bin/dnsmng '--update' 'mydomain.test'
[2015-06-10 16:42:43] DEBUG [util_exec] [5578bd6355bc3] Finished in 0.06322s, Result: TRUE
[Code] .....
So from what I can see the domain +100 is re-creating the domain whereas domain 1 is not - it's just updating it, even though both json commands show the update statement coming through.

my server CENTOS Enterprise 5 i686 with apache 1.3.37 with whm 11
Another note : this server not running on main site but run only on the dns (two server one domain name )
I currently have 2 web servers both running the cPanel Control Panel.
Out of the two servers only one is used and the other is just used currently to test scripts. It has come to a stage with the website capacity that I now require both servers to run in con-junction with each other to spread the load.
Questions:
1) There is a file upload service, How would you go about networking both the servers to allow remote removal / uploading of files to different servers. Eg, If user is on server 1 and files are stored on server 2. Also deletion of files etc - The website is programmed mainly in PHP.
2) File updating - The website is constantly being updated and therefore both servers will need the PHP files to be in sync. How would you go about doing this?
Both servers are at the same Data Center location.
We are looking for KVM/IP solution for multiple server. Where we can add the users remotely and give temporary access to the server owners. Once they are done we remove them from access list. So it can be used by someone else.
Anyone know for KVM/IP solution with kvm switch which can solve our purpose of KVM.
I currently have two servers, one is rhel 5 with cpanel, the other is windows 2003 with plesk 8.4
Each server wants you to setup a Hostname... one that is FQDN but not being hosted on that server so I setup a generic dns domain as follows...
SERVERCODNS.COM
Now for the hostname I setup both servers to be use this domain but different prefix... so...
SERVER1.SERVERCODNS.COM
SERVER2.SERVERCODNS.COM
Is this ok? Will I have problems?
My cpanel continues sending me emails nightly that my DNS is routing to another ip?
which bring sup my next question...
Is is ok to NS1.SERVERCODNS.COM, NS2.SERVERCODNS.COM for say the RHEL server and then DNS1.SERVERCODNS.COM and DNS2.SERVERCODNS.COM for say the windows? Is this going to cause problems?
Whats the difference or proper procedure for setting up DNS with my registrar (*ENOM) vs in the control panels they have Nameserver tools?
if it is possible to use more than 2 regular DNS entries across 2 hosts? So if a site goes down the other host picks it up?
View 12 Replies View RelatedI have a website.
I have it on 2 different servers.
This is because if the first server goes down for whatever reason, i dont want the site to go down.
To get this to work, is it just a case of adding more nameservers to the domain?...
becuase this doesnt seem to be working... the domain seems to always resolve to the server that is listed last in the list of nameservers...
Has anyway come up with a way to have several servers connected to one external CD-ROM on a USB Hub/network? This could allow a few external CD-DRIVES to handle a whole rack and the possibility of setting the bios via KVM/IP on a server to boot from CD, then it would boot from the CD tied in on the USB "network". Maybe using a USB hub? Or would this cause possible security issues having multiple servers tied in via USB ports?
I would love to have the ability to have maybe 3 or 4 CD-ROMs tied into multiple servers for OS installs remotely without having to actually go into the DC for this. You could put the CD-ROMs on your APC reboot and just turn on the one you need and set the bios to boot from CD (ie: one drive could have CentOS, one could have Windows, etc)
I'd be interested in some ways people have done this or what they use.
I have a firebox firewall and two servers. I don't one machine to see the other one the network. The servers are for two different clients. However I would like to be able to access a backup folder on Server 2 from Server 1. What is the best setup for this?

I have 2x servers with the following os/control panels:
1x Windows Server 2008 running Plesk 9.2
1x Centos 5.3 running cPanel/WHM
What I wish to do is to point all of my domains to the nameservers:
ns1.domain.com
ns2.domain.com
But, the domains hosted could be on either of the boxes above (because some sites are ASP.NET and others PHP).
Each of the above machines are running BIND and I have not yet setup nameservers on either of them. How should I proceed with this?
In addition (for arguments sake), if I then add additional servers how would I then achieve the same?
If there's already stuff around on the forum (I've done a search but found nothing specified to my issue of running a windows and linux box with completely different control panels) please point me in the right direction.
A website I am involved with may soon hit a problem due image uploading being stored on only one server. We are unable to find a realistic solution which would allow us to upload images from 1 central location.
The website is programmed in PHP and is on a standalone web-server - currently the images are uploaded to the same directory as the website however we are looking to move the images to another server for scalability.
Is it possible at all to upload using a directory link of some kind, eg, the directory would be /serverip/path/to/images which you would upload to? Or any other realistic approaches that you know off.
Is it possible to combine multiple servers via "Configure Cluster"? Will the hosting domains use same ns1.mydomain and ns2.mydomain.com if one server is located in UK and second is in USA Datacenter. Can somebody provide me information with explanation?

Basically, our goal is to have our own store for Lean Bulk, but it will be run by a different company, and will be on their server.

Either one works for me. However, the tech guy that runs all the stuff for the store, is trying to tell me that this is "impossible." While it might be somewhat difficult, I have a hard time believing anything is really impossible.

Personally, I think this looks unprofessional, and would rather stay away from this solution.
I purchased a domain, domain.com, from GoDaddy.
I have 5 servers, 2 running CentOS and Apache, 3 running Windows Server 2003 and IIS. Each server has it's own dedicated IP address, so I can access each site by going to [url]
Would I would like to be able to do is set each of these servers up with a subdomain on my domain.com. So I would have [url]going to one server, [url]going to another server, etc.
I logged into GoDaddy's Domain Manager. However, it appears that the only form of subdomains they have is redirection. So while I can create server1.domain.com, it merely redirects to [url]
I can mask the forward, but this creates problems with the login on the servers because they use cookies. In addition, the address always appears as [url], it doesn't have the "index.html" or "/login/login.aspx" when
I click links. The actual links appear as "[url] and not "[url]
Is there anything I can do? I want the subdomains to point to a particular IP address, not redirect.
I have a server with plesk8 installed. I forsee a time when I shall need either to move to a new bigger server or to add a new bigger server to what I already have.
Problem is, my isp says that PLESK will only work on single server set-ups and can't work in a multi-server environment.

I was talking to my host the other day about configuring multiple servers as a private LAN. I was wondering if anyone has successfully set up a configuration of using separate servers for each task for shared hosting accounts. I.E. Having certain servers as web servers and others dedicated as MySQL servers, e-commerce servers, mail servers etc.
Does anyone do this? I can see it boosting performance.
I run a small hosting company and i have been using multiple (different) nameservers for different servers, for example...
Nameserver IP
ns1a.domain.com 192.168.0.1
ns2a.domain.com 192.168.0.2
ns1b.domain.com 123.123.0.1
ns2b.domain.com 123.123.0.2
How do i make it so i can have ns1.domain.com and ns2.domain.com pointing to all different my servers?
how to make it so if the server that hosts my website receives too much traffic it will go to a mirrored copy of my website on another server? I want to make sure that it doesn't go down in the event of a big boost in visitors.
View 5 Replies View RelatedLets say for example I have 10 servers independent of each other. I want to be able to have only 2 Nameservers, NS1 and NS2 where all the domains should resolve to and then they should be handed off to one of the 10 servers. I dont want to have 20 Nameservers for example NS1 thru NS20 for all 10 servers. That would also be a waste of IP addresses.
I have a few murky solutions in mind. I would appreciate if someone would shed some light on the issue,
I'm planning host multiple game servers on a single machine. I'm going to configure my own machine for this purpose. I'm uncertain on how powerful should I build my machine.
I'm going to host resource demanding games like Battlefield 2 and Armed Assault. Both of the mentioned games has a dedicated server application that requires roughly 2ghz of CPU power and 1GB to 2GB of RAM (depending on connected users) to run on.
Base on the above requirements, I'm going to put together a machine with 2 dual core Opteron or Xeon running at 2ghz and 8GB of RAM. The machine is going run 4 virtual servers with the game server application running on them. My configuration uses basic division to calculated the required CPU and RAM on my custom configured machine. Is this a practical approach?
Has anyone tried anything similar with xen? I'm worry about any performance impact that might happen due to overhead or shared cpu & ram cycle latency as game server demands real time performance.
I'm though about doing this because it's cheaper to rent a 1U rack space running 4 game servers than renting 4Us for the same purpose. Care to share experience or thoughts on this subject?
Is there an issuer that issues wildcard SSL certificate which can be used on multiple servers under the same domain name (like server1.domain, server2.domain, server3.domain...etc)?
