domain name system - Can I Point about 30 DNS Zone NS entries to the same two IP Adresses?

I have about 60 Domain Names That I Am Creating Private name Servers For. Is it possible for me to just point ns1.mydomain.com, ns1.mydomain2.com, ns1.mydomain3.com etc. to the same nameserver IP address through the DNS Zone Record for each domain? And if I can do that do I have to put the original nameserver domain name in the DNS Zone SOA or can i juts map it too ns1.mydomain.com? Does any of that make sense? Other wise I am going to create like 30 nameservers on this one machine. Also I am using all C-Class IPs. I don't want to create 30 nameservers on this one machine and waste precious IP addresses. Any tips?

Thanks in advance for your help.

I also forgot to mention that I am trying to keep the fact that these are all on the same server Private so the SOA record for each domain needs to point to its own nameserver not the domain name for the real nameserver.

Answer

This is my conclusion from all the help and information given:

Actual Name Servers:

ns1.maindomainnameserver.com = 123.456.789.1
ns2.maindomainnameserver.com = 123.456.789.2

DNS Zone Entries:

Zone: domain1.com 
SOA is set to ns1.domain1.com
NS is set to ns1.domain1.com and ns2.domain1.com
A record ns1 = 123.456.789.1
A record ns2 = 123.456.789.2


Zone: domain2.com 
SOA is set to ns1.domain2.com
NS is set to ns1.domain2.com and ns2.domain1.com
A record ns1 = 123.456.789.1
A record ns2 = 123.456.789.2

Zone: Domain3.com (shares nameservers with domain2.com)
SOA set to ns1.domain2.com
NS is set to ns1.domain2.com and ns2.domain1.com

From what I have gotten from everybody, this should work and mask that domain1.com and domain2.com share the same nameservers. And in the end my WHM Nameservers List should only contain:

ns1.maindomainnameserver.com = 123.456.789.1 
ns2.maindomainnameserver.com = 123.456.789.2

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits, ...

linux - Awstats - outputting stats for merged Access_logs only producing stats for one server's log

I've been attempting this for two weeks and I've accessed countless number of sites on this issue and it seems there is something I'm not getting here and I'm at a lost. I manged to figure out how to merge logs from two servers together. (Taking care to only merge the matching domains together) The logs from the first server span from 15 Dec 2012 to 8 April 2014 The logs from the second server span from 2 Mar 2014 to 9 April 2014 I was able to successfully merge them using the logresolvemerge.pl script simply enermerating each log and > out_putting_it_to_file Looking at the two logs from each server the format seems exactly the same. The problem I'm having is producing the stats page for the logs. The command I've boiled it down to is /usr/share/awstats/tools/awstats_buildstaticpages.pl -configdir=/home/User/Documents/conf/ -config=example.com awstatsprog=/usr/share/awstats/wwwroot/cgi-bin/awstats.pl dir=/home/User/Documents/parced -month=all -year=all...
