My sites all respond very slow (VPS) at the initial loading, that's why I try to check all dns settings.
My current resolv.conf
nameserver 64.235.32.203
that is the ns of my hosting provider.
Would I have an advantage if I add another and if so can I simply add my own nameservers?
I have a new VPS server in which I did not configure the /etc/resolv.conf file. My VPS has three domains that are all working and resolving fine. But I keep getting an email from my provider that says this:
The hostname (v6.volumedr.com) resolves to. It should resolve to xx.xx.xx.xx. Please be sure to correct /etc/hosts as well as the 'A' entry in zone file for the domain.
Some are all of these problems can be caused by
/etc/resolv.conf being setup incorrectly. Please check this file if youbelieve everything else is correct.
You may be able to automaticly correct this problem by using the Add an A entry for your hostname ' under ' Dns Functions ' in your Web Host Manager.
Why does the actual server hostname need to resolve via dns?
I have confirmed that /etc/hosts looks good and I added an A record in my WHM for each domain. Do I need to configure the /etc/resolv.conf file too? Do I need to list my three domains and my server hostname(v8) and then my two primary DNS servers?
I'm supposed to be completing a server migration on Saturday night. But I have one teeeeny tiny problem....
I have no DNS/nameservers provided by my new DC for the resolv.conf.
They have them - but I don't think they operate like true root nameservers or something. I keep getting a ton of Unroutable Mail Domain errors for server email that should be leaving the new box.
When the resolv.conf was set to use the 4.2.2.x dns servers - it was working fine.
And I don't know if it's ok to just keep it using those or not?...
What other DNS servers can I use for the resolv.conf? Any DC's nameservers? Are there "public" ones available somewhere?
Is it better to put the IP of your server on the first line followed by the dns servers from the datacenter? And, how do you make the changes go in effect? I assume you just restart bind?

how to set up /etc/resolv.conf to use the rotate option.
I've tried:
options rotate
options timeout:2
nameserver X.X.X.X
nameserver X.X.X.X
Yes using NSLOOKUP and DIG both always return results from the first name server if it is up (no rotation) and when it is down, the timeout is the default 5 seconds (not the 2 that I specified) before going to the second name server.
I have a VPS (ConetOS 4.4, OpenVZ), it all works fine, however on reboot, the resolv.conf gets reset to some nameservers that are no longer in use, How do I change this so after a reboot it uses the nameservers I am using now?
My current resolv.conf looks like this:
nameserver 85.234.133.209
nameserver 85.234.144.209
It 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

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" {

Resolv Entries (space Separated)
I just got a very cheap box intended to learn HyperVM/OpenVZ. just got it tonight and got 5 IPs. So I add those 4 IPs in the Resources > IP Pools section. I don't know what to add in the Resolv Entries (space Separated) field.

I have 2 servers hosted with SoftLayer, In 22 Jun, I had reboot my servers, one of them didn't start and then SL said that it's was a reslov problem and we fix it, after that day, I start seeing all my websites traffic start go down , I check Google Analytics and the visitors number is going down everyday, I open a ticket and say that to SL and i think it's was a DNS problem they tell me after a lot of replys that they fix it and i must wait for 72 hours that need for the dns to be updated worldwide, I didn't say that SL support is bad no they are very very helpful support and many thanks to them, but i wanna to listen to your opinions here about my problem, and from where it's?

What happens if your primary nameserver goes down? Meaning that it goes completely off the net, not even denying dns requests but completely ignoring them.
I'd guess that resolvers would query the secondary NS after a specified timeout, but what is that timeout set to? Does it differ from ISP to ISP? How much of a slowdown are we looking at for end users?
would it be possible to have my main box running apache, a second box for dns/other and an offsite secondary dns such as DNS1.PUBLIC-DNS.NET?
Is it possible to authenticate the primary and offsite secondary nameserver so the zone is transferred to the secondary? Would i need to pay for a special service, or do free ones exist? Are there any security implications with zone files being transferred out over the public internet, would a vpn need to be configured or can the process be encrypted via the transfer procedure?
Finally, how would this affect the way the entire virtual hosting works? I know when the nameserver on the host machine serves resolves a name request for a computer trying to browse the site in question, but when the actual http request goes to the web server does it incldue the domain it is looking at also?
I just ran into something about Secondary DNS services.
What exactly is that?
Is that where if my primary name server goes down, a secondary name server kicks in and resolves all my donmains to another server somewhere?
I've been thinking about getting setup with some kind of fail safe setup in case my primary name server goes down.
Would Secondary DNS services take care of that?
If so, anybody know where I can find a reliable, affordable secondary DNS service?

View 3 Replies View RelatedI have the following three servers, which I'll call A, B, and C:
Server A - Web hosting server that uses cPanel on CentOS.
Server B - Free subdomain service (similar to afraid.org but on a much smaller scale), using PowerDNS with a MySQL database backend, on Debian.
Server C - Backup DNS server for the cPanel web hosting server, using the free cPanel "DNS Only" on CentOS.
Originally I had just A and B set up (they're two separate VPSes on the one dedicated server, I own the dedi and some friends and I have VPSes on it). Now I've got a VPS at a different data centre, and am using that for C.
To have a secondary DNS server for server B, I believe I can use MySQL replication to replicate the PowerDNS database to another server, then have a PowerDNS install on that server. My question is, is it possible to have server C as a backup DNS server for both server A (cPanel server) and server B (PowerDNS server)? ie. is there a way to check both PowerDNS and the cPanel BIND9 for domains (have them on different ports, and make one query the other if the lookup fails, perhaps)? Or perhaps use both the MySQL backend and the bind backend simultaneously in PowerDNS, and replace bind with PowerDNS (although I guess cPanel wouldn't like this)?
i have just bought a dedicated server with 2 ips.
i already put type master in named.conf along with a zone file having 2 nameservers pointing to A records
ns1 IN A 1.3.5.7
ns2 IN A 2.4.6.8
how do i setup ns2 (secondary nameserver)? how do i know it is running?
I have two nameservers, each running physically on a different server on different networks. Now I've noticed that whenever the primary NS goes down, clients requesting authoritative NS record lookups refuse to connect to the secondary NS, which I know is certainly up and running. The secondary NS has its own zone files and when you specifically request that server to resolve NS requests, it does the work. But generic NS lookups without specifying the server appears to fail when the primary server is down.
Does anyone know what might be happening here? I know that the domain registrar has both nameservers recorded for the domains I'm trying to resolve, but what is the point of a secondary NS, when it isn't contacted when the primary nameserver is down?

I am developing a site for a new company that will run under a medical engineering firm. I'm currently the only employee and am setting up websites and graphics for the company, but working out of the same office as everyone else. We currently have a VPS through iPower to host our site on, and everything is dandy. However we only own one IP address on the VPS, and I want to be in charge of my secondary nameserver, as I will also eventually use it as a secondary MX server. I have never done this before so I have a few questions about it. My previous experience has all been graphic design and web design, not much on the hosting side of things.
1.Is it possible to run a server on a XP desktop just using Apache or similar software (and a dynamic DNS service)?
2. Would it be possible to run this through the company LAN and router to make it accessible via the web without any serious tinkering on their network? (it has to stay up, and I have no idea what kind of routers or firewalls they are using currently). Basically given the standard setup how hard is it to open up the ports on the router(s)? I've done this only on a home router before, so I assume it can't be much different.
3. How do you go about doing it?
I've recently got a server with DA panel and a secondary SCSI 15K to put on mysql which I believe should improve the preformance.
View 1 Replies View Relatedclarification on DNS.
We currently have gps devices which report x,y coords. The devices currently report to a fully qualified name: servername.mydomain.com. And only one fully qualified name.
We would like to have redudancy, so if the main server goes down, then the secondary takes over. I assume this is accomblished via DNS.
So out first task is to create name servers at our domain registar and have them register them, for example:
ns1.mydomain.com -> FIRSTSERVERIP
ns2.mydomain.com -> SECONDSERVERIP
Then on the both servers we setup DNS to accept the a record of servename.mydomain.com points to? This is where I get confused. Does the firstserver DNS say point to itself, and the second DNS server point to itself?
in setting up Primary & secondary MS DNS server for MS WIn 2003 server,
View 5 Replies View RelatedI have 2 servers 1 US and 1 UK.
What I wanna do is synchronize both of them using rsync. Once they've got synchronized, the UK will be the primary server and US will be secondary, in case the UK goes down.
my questions are
1. Is it possible that when the UK goes down, the A records for domain.com automatically switches to the US server so it can take over while UK is down.
ie. UK ip 112.113.114.1
US ip 222.111.444.5
domain.com A records = UK ip when up... but when UK is down, A records automatically changes to US ip.
2. And when the UK server goes up again, whatever changes made to US server will be pushed to UK. May it be files, accounts or e-mails.
I.E.
UK and US are synchronized every 30mins. UK and US both have e-mails 1-10.
Just before the sync time, UK server received an e-mail 11-15 then goes down. So the US Server will take over but do not have 11-15 mails, since it was received before sync time. During the UK downtime, US server received e-mails 16-20.
When the UK server goes up, will it be possible to sync both servers that both of them will have the e-mails 1-20?
I hope you get my point...
If these are not feasible, what can you advice as an alternative solution. All I want is to avoid downtimes, especially with mails as the business relies on this.
