Does anyone have experience with DNS issues?
I'm hosting a few sites with LiquidWeb (freeteams.net and laxteams.net are the big ones), who's been a terrific host, but I occasionally have some issues trying to access my sites. It occurs only occasionally (maybe 10-20 people have let me know in the past year), but with users in different locations and on different ISPs. It seems to also only occur for a couple of hours.
When they try to type in a specific domain, it won't show up in their browser (browser-independent, I've tried it in Chrome, IE, and Firefox.) However, when they try the IP address directly, the site works. I have about 4 sites on one server, all with their own IP address, and the issue doesn't affect all the domains at the same time.
LiquidWeb says it's an ISP issue (they've checked all the settings on the server, and everything looks ok.) I tend to agree with them, because when I or my users switch from using their ISP's DNS server to OpenDNS' server, it works. However, it's happened at a number of different ISPs around the U.S., including universities, which makes me think there's something I can do to solve the problem. Also, I don't want users to have to change their computer settings.
Also, while I can't access the domain in the browser, I am able to ping the domain, and it will respond.

I have a customer having trouble with his email today, his domain seems to be unknown for some servers, even the host server refuses to ping to it
[root@svr01 ~]# ping perform.com.co

If I ping from my location it works fine
C:>ping perform.com.co

Ocassionally some users have problems to connect the their websites, they can connect to the server via browser and can ping it and tracert the server IPs fine, they can also browse domains having a dedicated IP address. But they can't connect or ping their websites from their end, basically I think the domain name is not resolving.
From our end and the rest of users everything works fine.
Once I get a complain of this type I try whatever I can do
Check to see if their IP is not blacklisted
Restart named service
Restart apache service
But most of the time this doesn't work at all.
Exactly as the problem comes it goes, nothing I did seems to have any effect on the solution. It goes and ocassionally reappears.
Would you suggest me what would I do to find where the problem is and try to solve it.

A client recently moved one of their domains to one&one (night mare I know) he then asked us to repoint the domain name to our servers using out name servers.
We have done this and it is not resolving to our server.
The problem is that the site is no longer showing and their emails are down.
I used a domain dossier and the DNS record looks like it should be changed but I'd like some confirmation on this.

For some reason, for one of my sites, www.domain.com resolves correctly -- however, domain.com resolves to the Cpanel default page.
I've set up this domain the same way I set up my others. Also, I checked the DNS entry and see nothing wrong w/ it. Here's a screenshot of my DNS domain zone file:

We have a full rack of servers at an XO datacenter. Most of these servers consistently need to go out to the internet to retrieve various URLs. Essentially, the servers are spidering, like Google does.
Lately we have noticed that the DNS servers that XO provided, which are in the /etc/resolv.conf files for each server, have been randomly failing.
Is there any reason that I can't set the servers to go to the root and use that for DNS? I need to bypass the XO DNS servers some how.
One of the options that I am considering is setting up a dedicated server that can provide recursive DNS to my other servers and have that server ask the root DNS system for records when it is not in the cache.
The other option that I am considering is finding a company that I can buy the ability to do recursive dns on. The onyl one that I have found so far is DynDNS though, and I have been looking for about two hours.
[url]
If anyone can make any suggestions to how I can get around the XO issue I am having or provide suggestions to a provider of recursive DNS servers (not managed, unless recursive comes with it),

I'm making the switch from windows to linux for our company web server. We've been running IIS/MySQL/PHP for years and with the OS cost to upgrade the server switching to Linux seems an obvious choice. What frustrates me is that none of the Distros seem very quick to use the latest versions of the AMP components and compiliing from source seems an unnessary hassle. I've tried Ubuntu server so far which has Apache 2.2.9/Mysql 5.0.67/PHP 5.2.6 with no room to easily upgrade any of the components (our WIMP server uses the latest MySQL/PHP).

I have a local server named as 'EPBX' which monitors the working of the telephone system and makes their log entries. Recently its HDD partition got crashed due to which it was formatted and had re-installed Windows server 2003 after which I am facing some problems as given below:
- The IP address assigned to this server is 192.168.100.2. I am able to ping the IP but unable to take the console of the software from some other local PC.
- Also when I try to trace the IP using the tracert command first it resolves to the ISP's router and then to the server. But the router is not at all asigned a local IP. I have assigned a global IP to it. (Screen shot of the same has been attached)
- It would be very difficult for me to change the IP address

Just got set up with a new VPS and while looking to see if my IPs were blacklisted, I came across a RDNS warning. I've been on some form of shared hosting since I've been on the Internet, so much of the VPS stuff is new to me (though it is managed). Everything I've read says that RDNS is important for sending mail so the receiving end can verify where mail is coming from, but I thought I would ask here regarding my specific issue.
I've got four IPs on my account. The first ip, x.x.x.67, is the host IP(ie host.example.com). Most of my domains are using that IP at the moment since I just got set up, but I do have another domain on the last IP in my account, x.x.x.70. When I first did a RDNS check on my main IP I got a domain that I've never seen before, and all other IPs on my account don't resolve at all.
I sent a ticket off to the host, and they set the RDNS record correctly for the main IP on my account, but the other three still fail to resolve. When I asked the host about it in a ticket, the response that I got was
Quote:
Normally, we set RDNS for the main IP address to hostname of the server.
The RDNS for your server has been setup properly. Please get back to us if you need any further assistance.
So basically I'm clueless. Does it matter that the other three IPs I have available don't resolve at all? The domain on the x.x.x.70 IP, which doesn't resolve, is an e-commerce site that depends almost exclusively on e-mail for its business. Doesn't the lack of RDNS resolution mean that I'll be out of luck sending mail to AOL, Yahoo, Hotmail, etc etc on that account? Even though I don't have sites on the middle two IP addresses yet, I fully plan to put sites there within the next couple of months... could they have the same problem?
It's frustrating since I obviously have no control over RDNS records, and the host's staff is being a little obtuse about it.

We've just been told by our data centre that our server that we use to host our web design clients has been disconnected due to massive volumes of traffic from or to the server.
They said I will need to log into a KMV/IP in order to investigate.
I have no idea what I am doing and was wondering if there are any users out there that could give me some pointers in finding what is causing this DoS attack?

I'm setting up a VPS server on Slicehost, I've followed the guide on howtoforge for debian and have everything installed including ISPConfig3. Everything seems to work fine at the mo but when I check the memory usage, i see that I'm using around 490/500mb of my 512mb setup. Its a Xen setup so I understand this is real memory available but I'm not sure if this is enough.
I will ultimately be running around a dozen sites, some static and some dynamic. There's one Mambo and one Joomla site there but they don't update. The rest are all php/mysql sites that I've built myself but again, they don't change that much. None of the sites currently see more than a couple hundred uniques a day, and some only a handful, so usage is not high. Most of the domains have e-mail accounts attached, but its only moderate usage with around a dozen addys per domain max.
So, do I need more memory or will 512 be enough? Is there anything I can do to reduce the load and give myself some more room?
I'm moving from a shared hosting environment and while I'm comfortable setting up the server, I would rather have a simple mail manager that would give users more control over their accounts, change passwords etc, which I'm hoping ISPConfig3 will be able to help with, but thats probably best discussed in another post.

an example Anaconda file that I can use to silently setup CentOS 5 VM's (under Xen, also CentOS5).
Typically, I am looking for LAMP+standard tools, e.g. FTP, SSH, mail, etc.
I tried to create one myself, but the configurator seemed to ignore my specifics and install large groups of stuff anyway.

Do you realise that the x64 Opteron is needing an avarage 1.7 %MEM for each Apache process while the Xeon just needs 0.5 %MEM?
Since both use the same version of phpBB and the same version of CentOS5, while the only difference is one is x64 and the other i686, I wonder if this has to do with the way memory is handled by the x64 CentOS5.

We have few domains which resolve properly for say 1 day and again next day its not resolving.
Sometimes this ON/OFF happens several times a day. This happens when we use the 2 name servers assigned to the server.
this problem does not happen if we use a manged DNS service for the domain names.

We have a spare powerconnect server in work and i was looking to set it up as a web server for a company intranet - more to gain experience in configuring a web server than anything else.
I decided to go with Fedora 8 as i'd used fedora previously and followed the LAMP tutorial on HowToForge.
However i've come across a problem which i just can't seem to resolve (after pretty intensive searching). So, i guess this post is in 2 parts.
Firstly, the error i'm getting is with mysql only. The error message is:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
I understand this may be a generic error but i'm not sure what other information would be useful.
Secondly, as this is my first web server - have I made the correct choice in terms of linix release or would something like CentOS be more suitable? I'd like to get this right from the start now that i have the chance.

I've got a VPS account & when I connect to sites on the VPS, more often than not the browser times out. I click again & the site comes through.
I use Firefox & have tried in other browsers with similar results.
The VPS has 384mb dedicated RAM, with 512mb burstable - not much I know but...
I was wondering about possible reasons - could it be simply not enough RAM, could it be a bottleneck with the hosting company, could it be a problem in the setting up of the nameservers? What would seem more likely?
It's a shame as the tech support have been superb but it's too risky to use for reselling.

i got too many logs on Lame-server resolving i my log.
every second about 10-20.
Jul 23 11:31:33 ns1 named[15967]: lame server resolving '92-49-205-1.dynamic.peoplenet.ua.mydnsdomain.net' (in 'mydnsdomain.net'?): my.ip.add.ress#53
Jul 23 11:31:33 ns1 named[15967]: lame server resolving 'www.mydomain.com.mydnsdomain.net' (in 'mydnsdomain.net'?): my.ip.add.ress#53
so i turned of the logging and start search the web on possible reasons. However the only once i found where mostly "in case of the domain is not hosted on the server". But in my case the domains in questions are on my server and show in the log as lame server resolv.
They say it has to do with server is not authoritive for that domain.
So how i am gonna fix this?
With digs, and nslookups, i got not errors at all.
But if i try to change a DNS i got a message back from a provider saying that the domains is broken.

to set up a little server that will have LAMP installed on it. All it will do is host a small program that runs on PHP and mySQL and will only be used on an office network with about 50 employees.
How well would this server run if the hardware was rather modest (667Mhz, 128mb RAM, 10GB HDD)?

I want to run a firewall on my LAMP server. I'm using Ubuntu 6.10 server. Previously I used firehol to achieve this but the new version of the kernel I'm using doesn't seem to be compatible. So I went to try ipkungfu instead and that didn't work saying "my kernel doesn't support LOGS". So basically I'm going to need to play around with iptables myself. I've been reading up on TCP/IP in order to learn how to do this but, well, it's really not very much fun. SoDoes anybody have a bunch of iptables commands I can use to set up a basic firewall to block all requests except certain ones (I don't need anything complex like forwarding)?

Because of the security issues inherent in controlling DNS servers on other VPS/servers that run other processes, host websites and store mission-critical data and for other reasons related to control, we want to keep our DNS server separate from our other servers and our own desktops. Therefore, we're going to get a small VPS for this purpose.
We won't totally cheap out on this so we'll be getting a quality VPS from a good provider. But, we probably don't need more than 5 or 10G of HD space but we wonder how much RAM and bandwidth we need to run something like MyDNS with MyDNSConfig with a MySQL backend.
Also, what's the best Linux distro for this kind of thing? We use CentOS with facility but are not afraid to try a new one if it's a better choice for this purpose.
