Reverse Domain Name Server (DNS) Problems With My Provider. Why?
Mar 20, 2008
Maybe somebody here can shed light on this issue. I have a VPS that is hosted at the Colo4Dallas datacenter. I have purchased a block of 5 IP addresses, and then requested reverse dns zones be added for each IP.
The original 2 IP addresses that came with it, adding reverse DNS zones were no problem, it was done within a day. For some reason though, these additional 5 IP addresses they are having a horrible time with getting the zones added. My host that I have the VPS through said they put the ticket in, and Colo4Dallas is saying they may not be able to add the reverse DNS entries for some reason. I could not get any technical detail yet though because they are still working on it.
My question to everyone here is.... why? Granted I do not know *THAT* much about the datacenter-side of things, but it would seem to me that an IP is an IP, and if you could add the zones for the original 2 IP addresses, why is it not as easy with an additional 5? I *have* to have reverse dns entries for these IP's for email reasons for my customers that will be on these IP addresses.
Can anyone shed some light on what the technical problem could possibly be?
But do i need to speak to the datacenter to add the reverse dns entries for my domain on their nameservers? What about if i host my nameservers offsite, but then have my webserver/mailserver etc inside the datacenter? Would i need to request the datacenter where the nameservers are hosted to add the reverse ip entries for the domain, and then the request the same from the datacenter for my web/mail servers to add the reverse entries?
I was issued two IPs for my DNS server.My DNS server is up but when a domain is using the new dns server.I did a dns check and was told there is no reverse dns.Can I do it myself by setting on the DNS server or I need to get my ISP who provide me the IP to do it set the reverse dns?
I've been having a problem for the last year: most of my pages are indexed by the IP address - not domian name and I suspect it is because of the lack of reverse DNS
Is my ISP supposed to add reverse DNS or should I buy one from dyndns as I am using their DNS service
I will be storing personal customer information in mysql, so security is driving all my requirements. I was thinking the architecture will be :-a dedicated web server within a DMZ and placed behind a firewall and border router.
a dedicated database server inside the internal network behind another firewall, All running Linux
building out and management of the servers to be done by hosting provider or third party Please feel free to comment on this setup.
QuestionsIs a reverse proxy a benefit for security.
Am I right in saying that a reverse proxy hides the OS and server details from prying eyes and provides another layer of security
if a reverse proxy server is a benefit, is it normally the default architecture at most reputable hosts.
Is it possible to implement reverse proxy for Sever-A through Sever-B.
The issue is let's say, Server-A is located in Network-A, and the Sever-B is located in Network-B. And the users in Network-B are allowed to access only to Sever-B while the Sever-B itself can access to Server-A. So, when the users from Network-B access to Sever-B, the traffic will be proxied through Sever-B to Server-A transparently without letting the users notice about how's the traffics go. The Server-B will be linux, thus squid is the primary proxy application to deal with. Is it possible to do with squid or it needs some other application?
How about a comparison of mod_proxy for apache vs. squid as all Sever-B should do is forward the requests coming from Network-B to forward to Sever-A and acting as a middle box between the two network scopes transparently. All the users in Network-B should do is accessing the Sever-B and the requests will be transparently going to Server-A without any configuration is done at their browser or any kind of NAT/Firewall rules on either of the networks.
We have been using Apache 2.2.x with reverse proxy modules for our clients to access their OWA servers for over a year. I want to get us to Apache 2.4.x so I setup a test box with latest 2.4 on it. I fixed the config file issues since 2.4 has changes in it. OWA proxy is working on my test server with Apache 2.4. But with 2.4 I do have an issue I cannot figure out. Note that this does NOT occur with Apache 2.2. I get the following errors when using ActiveSync through reverse proxy:
[Thu Oct 17 12:19:11.670665 2013] [proxy_http:error] [pid 748:tid 8440] (OS 10060)A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. : [client x.x.x.x:20311] AH01102: error reading status line from remote server mail.nameredacted.net:443 [Thu Oct 17 12:19:11.670665 2013] [proxy:error] [pid 748:tid 8440] [client x.x.x.x:20311] AH00898: Error reading from remote server returned by /Microsoft-Server-ActiveSync
So somehow with Apache 2.4 there is some sort of timeout that was not there with 2.2.
We're currently in need of a reliable provider in California. We're currently using ServerBeach and their LA data center but we're having major issues with their service and support (highly recommend staying away from them at all costs).
Normally we go through referrals from other data centers but we're having a hard time locating a solid provider in the California area.
Our company are soon to launch and we are in desperate need of a dedicated server so our coder can code all of our sites and upload them. We have a server with thevpsguy.com which has been down since last Monday! I have only received very limited support from Ian the owner and now I am beginning to give up hope on him sorting anything out because he ignores all my emails and makes false promises.
Who are the best dedicated server providers?
I want someone with good support, but I still like the personal touch so not huge companies.
My friend asked me that, "Hey! How are you doing? I am thinking about buying hosting from this new-webhosting-company-to-me.com . What do you think?"
I replied him that,
"Well, I had a server with them.. Let me tell you something about them,"
"Value for money: 4/5 points" (their hardwares are worthy) "Setup Time: 3/5 points" (they took 2 days to setup. But i read 24 hours setup time on their homepage)
"Friendly Support: 5/5" (those dudes were skill full and friendly when i asked for os reinstall and other support requests)
"Datacenter/Infrastructure: 4/5" ("good network and I got 2 hours downtime only once")
==================================
Well, I said above 4 things to consider, before buying from a host.
What would be your top 5 considerations about any host to recommend your friend?
Due to some recent negative experiences, one of my customers had to cancel their account with IBackup.com's Pro services. It had provided exceptional reliability and did Windows backup of the System State, Exchange Server, SQL, and provided file versions going 30 back. But I couldn't get anywhere with technical support for 2 weeks on why it would freeze during the backups. The final straw came when I installed it to a brand new server and had the same issues.
I'm looking for a suggestion on a provider that does at least file-level backups and Exchange backups. I've looked around online, read reviews, but it doesn't look like the providers do Exchange backup. I don't need mailbox-level backup, just brick-level for disaster recovery. File versions going back (in case a user makes a mistake and wants to restore an old copy) would be nice, but not required.
I have several sites with Godaddy, but their lack of any real support leaves something to be desired. Does anybody know of a decent provider that has options for database support (mysql) and the like?
Most of our customers are going to be accessing the server from Europe and Asia and North Carolina, so I am looking for a dedicated server provider on the east coast.
I'd like KVM, network storage, remote backup if possible.
This is first time i am writing about hostgator using there service since 4 years.
I have 3 dedicated servers purchased with them within last 6 months and orderd for 4th server on 31st Aug 08. And now as business is growing i will need more and more servers every 2- 3 month. But its seems hostgator is not interested in business as they had already grown now. Even they don't care of their loyal customers who are them with years.
On 3rd day of orderd they told me my server will be deliverd within next 24 hours and on 4th day i contact them serveral times they keep on repiting they will upate and then they said server is out of stock and will be available soon and today is 5th day still there is no reply from them and when i contact them they clearly have no idea about it. Some says will get it soon and when i show my ticket. they say its still out of stock . When i contact with theplant.com datacenter they told me the server is available to order and are never out of stock.
I dont know whats actual reason.
Please help me guys to find good manage dedicated server host so i can cancel my order with them and go to another good company.
This is serious, please do not find the thread as SPAM, waste of time, or useless. I'm doing my research while at it.
Current Provider: ThePlanet CPU: Dual Core 3.2GHz (seeking 2.8GHz Dual Core or better) Memory: 1GB (seeking 1GB or more or better; unknown technical specs) Harddrives: 400GB Harddrive (seeking 400GB or more or better) Cost: ~$320/month (seeking at this price or cheaper) Bandwidth: 1500GB @ 100Mbps (seeking more than 1500GB, but @ 100Mbps)
So help me find providers other than ThePlanet (good hosting, but not good enough to help advance the webhosting business through over-selling). I am seeking for specs at, around, or close to the ones I gave above (monthly fee also). Reliability is a very important factor!
When I hit my server's domain it redirects me to one of the hosted sites' domain with a 302 redirect. It used to return the default plesk server page. How can I cancel the redirect?
We have a lot of unused domains that we'd like to setup domain parking for.
To keep it simple, we'd like to just change the namesevers to ns1.domainparking.com and ns2.domainparking.com (not real nameservers!) and the domains would then automatically show a simple web page.
We use cpanel servers and are wondering how easy this is to do? I've seem mention of wildcard dns? Is that the answer?
i have about 8 different domains i'd like to point to a nameserver (ns1./ns2.mydomain.com) on Win2k3 server, but i can't get them resolved through my nameserver without creating a manual forward lookup entry for each *parked* domain separatly..
Does anyone know how to resolve "parked" domains automatically on Win2k3 DNS??
I just can't find any answer for this, everything i've found required manual creation of lookup entries..
