if I do a reverse lookup on my server's IP it returns a host assigned by the data center. So is this something I should even be managing too or is that always left up to the DC? I run my own DNS for the forward lookup zones.
Also just a technical question, when you do a reverse lookup, how does it know where to look to get the host? I'm not sure I fully understand how these work.
I'm having tons of problems trying to get reverse lookup working on my dns server. I've scoured the net and tried lots of methods but so far none work.
Forward lookup DNS is working perfect, but reverse lookup is completely broken.

if its possible to change the reverse lookup, or at least i think thats what it is called.
I have 2 accounts on my CentOS, WHM/cPanel VPS and they are hosted on their own seperate IPs however when you do a lookup on one domain it also lists the other domain as being hosted on the server and vice-versa.
How do i change this so they appear like they are on different servers? Each one has their own nameservers which are on seperate IPs also.
Where am I sending e-mails from with the below settings:
(Is it mail.freesexdoor.com, www.freesexdoor.com, 64.85.161.123 or 64.85.161.124?)
My secondary question is: Is creating own reverse IP lookup to 64.85.161.124 possible and beneficial in my case? If so, what should I replace this SPF line with: freesexdoor.com. TXT "v=spf1 a mx ip4:64.85.161.123 ?all"?
I'm trying to improve freesexdoor.com's e-mail delivery ratio because hotmail and gmail deliver my PHP mailer's sent confirmation e-mails to the junk folder. I've done everything I can to improve the sent headers etc. so there's only one more possible way to improve it: (That I can think of). Freesexdoor.com is hosted on the same server as mitorahgames.com.

I'm by the way putting www.freesexdoor.com (PHP reported server name) to the Message ID: field in the e-mail headers. Would putting IP there perhaps work better? If so, which IP?
Somebody purchased a domain from a popular registrar. When you lookup the domain, it points to its own name servers (i.e. ns1.registrar.com and ns2.registrar.com), which means that it is hosted by them as well. correct?
this person is saying they bought their domain from the registrar, but they are hosted by company X. he says that he is pointing the ip address of his web site on company X to his registrar.
I want to know how serious following nameserver problem can be in reality:
[url] ?
From DNS timing someone could conclude it's a slow hosting.
Can anyone explain above results "accurately" ? I still don't know what's "good" result in DNS timing: A or F?
The problem is that
[url] loads slow (5-10 seconds on T1 connection), here's a speed test. I'm aware images and scripts contribute to slow site loading.
My question is: Beside removing some images from the Home page, is it any reason to change the hosting (regarding DNS tests).
Friend of mine asked me what "CURL named lookup issue resolved" means, he's got a CentOS 4 machine, with cPanel/WHM latest builds I tried recompiling apache and even cPanel at some point but no good..
View 1 Replies View RelatedI am having a problem. My server was able to ping google.com successfully before installing DirectAdmin.
However after installing DirectAdmin, I am no longer able to ping google.com anymore. I just get a host cannot be found error. This is the same with all other domains.
The /etc/resolv.conf is exactly the same, so I do not know the issue. I also have other servers using the same nameserver and are still able to ping and resolve successfully.
The main problem here is that exim no longer can send email as it cannot lookup the hostnames.
the error from exim is: R=lookuphost defer (-1): host lookup did not complete.
Thats the only error within the message.

ffmpeg: symbol lookup error: /usr/lib/libavcodec.so.52: undefined symbol: speex_header_free
I am using a centos 5 vps
I have six dedicated servers on a VPR. I use one of these as the Database server and the other five connects to that server to read the Database.
When I setup my scripts for the first time I used the external IP to connect to the DB server. Everything worked perfect for these weeks:
mysql_connect('174.xxx.xxx.xx', 'user', 'pass');
Since three days ago I finally received the internal IPs of my servers and now I use the internal IP of the DB server:
mysql_connect('10.0.0.1:3306', 'user', 'pass');
When I did this last change this my database started to collapse. Queries stuck on a bottleneck every 10 minutes. Here's an example:
40468 simon 10.0.0.7:47002 pkindigo_db Query 115 Locked update `captured` set hp_left = '79', status = 'normal', att1pp = '25', att2pp = '30', att3p
40523 simon 10.0.0.2:58080 pkindigo_db Query 115 Locked update `captured` set experience = '5120', level = '16', hp_left = '58', hp = '58', status =
... (tons of locked queries before) ...
As you may see table is locked since 115 seconds for a simple update... after some hours this ends on a "#1135 - Can't create a new thread (errno 13); if you are not out of available memory, you can consult the manual for a possible OS-dependent bug" and even some of my tables finally crashing.
I think that my Database stuck because of a DNS lookup delay. When I had this problem before using the external IPs, I added skip-name-resolve and the problem was fixed. But now with the internal IPs it seems that's not enough.
My MySQL server slowed down to a crawl a few days ago, and I finally fixed it by starting it without DNS lookups via "--skip-name-resolve".
I tested domain name resolution on the MySQL machine and it was able to return IPs from domains rather quickly, so I'm at a loss as to why DNS was the problem here? I am using "192.168.1.6" as the MySQL server's IP, in case that matters?
I have a couple of questions:Why is DNS resolution so slow when in the command line it's running normally?
Why does MySQL need to do DNS lookups at all? I don't see any log files that's converting IPs to host names or vice versa.
I want to hide my NS records on WHOIS lookup, or show a fake or something so that no one can find me, Is it possible,

Im using Ensim Pro and RHES 4.
I regularly have DNS issues with some of my sites hosted with a specific host... At random sites, the urls done resolve and I get a DNS error.
Just to find out that a few hours later it loads again without issues...
I always thought it had something to do with my ISP... My host says that there's nothing wrong with their DNS.
However, I asked a few people now and it seems they're having DNS problems too sometimes when accessing the problematic urls...

View 12 Replies View Relatedi have a dedicated server with 2 ips and i am planning to run a nameserver, mailserver and webserver on the same server. i heard that reverse dns is important. how do i do that?
My questions are...
1. will it work if i setup the reverse zone in my server? or should i ask my host to setup reverse ip for me?
2. Do i have to setup reverse entry to mailserver or domain or nameserver? which is important to have reverse ip.
i had some problem with my smtp server because of my PTR record
i create a new reverse zone and add a ptr record point to my mail.domain.com from my ip(38.100.214.200)

I'm with a German (dedicated server) Provider and have the ability to personalize the Reverse DNS settings through their CP.
No US provider had allowed me this setting before, so I'm clueless about it. Whats Reverse DNS, what if I change the current setting to like - rdns.mydomain.com? Whats the use?
some clarification with regards to Reverse DNS.
An example ip: xx.xxx.xxx.xx is owned by A Company via a DC. The they have their name allocated to the netname and description when i look up their ip address.
I have my ip xx.xxx.xxx.xx this is me and it currently contains my DC's name throughout when i look it up as the description and netname...
Both are from the same DC however the other company has their name allocated to the ip address and i would like to do the same. Does this require Reverse DNS? It dosent involve domains surely does it?
