Domain name which is registered on the DNS for an IP and the name of the host with that IP need not be the same. am i right? I mean domain name and host name need not be the same. Is this correct?

I want to use single label host names on my local LAN, without using any domain (at least no registered one). My machines should be named in a fashion similar to 'myserver', 'mydesktop' etc. so that i from a browser on any LAN machine may write 'http://myserver', and get the webserver on 'myserver' (so NO domain part, e.g. myserver.domain).
Do i need to create a DNS zone for each host or is there a way to put all host in a single zone, if so; which? Would such a name be considered a root domain?
Whenever I try to use the sudo command in the terminal I get the message unable to resolve host, then my computer name. Here's some command line output with some files which I think may be causing the problem. I have Operating Systems homework and need sudo
steve@steve-laptop:~$ sudo gedit /etc/resolv.conf
sudo: unable to resolve host steve-laptop
steve@steve-laptop:~$ cat /etc/resolv.conf

I have installed CentOS 5.4 machine named test.example.com (192.168.1.1)File /etc/hosts contains:127.0.0.1 test.example.com test localhost.localdomain localhostI have read that the loopback addres should not be assigned to host name,only to localhost and the host name should be assigned to 192.168.1.1, like this:127.0.0.1 localhost.localdomain localhost192.168.1.1 test.example.com testIs there any reason why it should be one or another way?
View 6 Replies View RelatedI have a domain I have never used for some years, the registrar put some adds in it, now I have hosted and configured this domain as a VPS and have started to put files in it but when I enter the domain in the browser, it still displays the adds index of the registrar although I have my own index file in /var/www/. I thought the domain was automatically "taken over" (I do not know the correct technical expression) by the hosting company when my hosting is accepted by the host after they install a bare distro. Obviously, my expectation was incorrect and there is something else I need to do.
View 2 Replies View RelatedI have a Ubuntu Server that is correctly set up and has been working for awhile. It currently has a domain (Registered by GoDaddy) and it is used as the main. I just bought another domain (From GoDaddy) and I want it to connect to the same server but a different section to host a second site completely separate from the first.
So this is how I want it to be setup:
Domain1 = /var/www/
Domain2 = /var/www/website2
When I put Domain1 in the url like www.domain1.com it will connect to /var/www/
When I put Domain2 in the url like www.domain2.com it will connect to /var/www/website2
I'm running CentOS 5.4 with sendmail. My computer hostname is bob.domain.com. Whenever I would nc -v 127.0.0.1 25 into sendmail I would get bob.domain.com on the banner. Whenever I send out email the emails would be user@bob.domain.com. I wanted the email to show up as user@domain.com. So in the etc/mail/sendmail.cf file I changed the line
Code:
Dj$w.hostname.com
to this
Code:
Djhostname.com
Now when I enter sendmail I see domain.com in the banner so I know the change took place. However, when I send email using
Code:
mail -s "test" xxx@xxx.com
then email still goes out as user@bob.domain.com. What other changes do I need to make?
I'm really new to this subject. Instead of purchasing hosting services from another party, what requirements are necessary to host a domain yourself, i.e.:
1. Minimal connection speed
2. Minimal hardware requirements, e.g. disc space
3. Effort to host domain and secure Slackware
4. Will an average ISP provide sufficient reliability, i.e. uptime, and bandwidth?
While in YAST2, everything seems to save fine except for the information in the "Host Name and Domain Server Configuration" screen. I have two servers side by side, the one works perfectly fine, the one does not. I can save the IP address and changes to DHCP and Static, but when I enter in the information for the Domain Name and Host Name, I click next, it saves, but when I go back in to it, the items I set are blank again. The boxes are not greyed out, you can type information in without error. When entering YAST, it requests the root pw which also works fine. I am not using any strange characters other than letters/numbers. I am going in to the screen by clicking network devices-->Netword Card-->Host Name and Name Server.

I have a server which runs postfix. The same physical server is running web and mail services for several (3) domains, which I have reserved for future use (nothing serious or valuable, just freetime activities). Server "physical" address (also static IP) is myhost.domain.com. Lets say the other domains it serves are first.fi, second.net ad third.com. I can receive mails OK sent to all of these, I have added those 3 "extra" domains to the mydestination line in main.cf. Sending e-mails also works fine, but the sender is [URL].. I want the sender to be firstname@first.fi
I tried setting sender_canonical_maps = hash:/etc/postfix/sender_canonical in main.cf, and sender_canonical contains:
user1 Firstname1@first.fi
user2 Firstname2@first.fi
and I run postmap /etc/postfix/sender_canonical, and e-started postfix. But if I send e-mail as user1, the sender becomes [URl].. so it re-writed the username part, but hot the hostname/domain part. I also tried setting smtp_generic_maps = hash:/etc/postfix/generic but the results were similar. What do I need to do to re-write sender for user1 (regardless of host/domain) to Firstname1@first.fi?
i am trying to get postfix to relay through my isp's smtp server, but i am getting an error.Host or domain name not found. Name service error for name=mail.grandecom.net type=A: Host not found, try again...i can send mail inside my domain, but when i try to send an email to a test gmail address i find the above error in the log.
View 10 Replies View RelatedI am managing a Fedora dedicated server with Plesk 9 and just recently moved the email for one of the domains on the server to Google Apps for business. Unfortunately, I cannot get email messages from the website forms to deliver to addresses on this domain. For anyone familiar with Plesk, I have disabled mail in the hosting settings by un-checking the "Activate mail service on domain" checkbox and there are no accounts in the domain. (Other readings have indicated that this should be enough to allow mail to be directed to the appropriate server). My MX records correctly point to the google apps mail server.
I'm quite comfortable with command line, but I know almost nothing about the sendmail program or its alternatives and my attempts at researching how to set up this relay has been futile. I'm pretty sure I'm using sendmail and not qmail or anything else from what the red-hat style "alternatives" symlinks point to. I've also checked the /etc/mail/access, domaintable, mailertable, sendmail.cf, virtusertable, local-host-names, sendmail.cf, and submit.cf and most of these files are empty (except the .cf files), and the sendmail.cf and submit.cf make no reference to the domain in question.
Here is the output from a sendmail test that was was not received. (Private data omitted of course).

Ok, I have a couple of SMTP servers for our infrastructure. They are running Postfix. I have them configured so that specific email addresses such as support@mydomain.com and billing@mydomain.com all go to a new support server that I am building with osTicket. Lets call that server SUPP1.
SUPP1 runs sendmail from the default install of CentOS 5 i386. At this point everything runs great. New emails get added into the osTicket system via a pipe in sendmail. Here's where the problem comes in. In order to accept mail, sendmail has to have the domain listed in local-host-names and the addresses in virtusertable. That works just dandy. But in doing so, sendmail believes it is the destination SMTP server for "mydomain.com". That means that I can't send mail from that server back into my normal SMTP servers. So things like the LogWatch, cron jobs, etc can't send notifications. Is there a way to work around that? For sendmail to ignore local-host-names for outbound email or something?
I have setup a home based web server to host a photo blog for myself and my friends. I will be running wordpress and possibly a phpbb3 forum. I'd like to open this to discuss server administration, server setup, and server maintenance. However, I have a pretty good start on all of those but serving a domain name to my static ip. Here my static ip is 24.10.202.144. I registered a domain through [URL]... It appears that I have the domain working to forward to my ip. However, I am still getting this output file from apache.
[code]...
I have tested the domain name across a few different computers on different ips. It works appropriately. I just want to make sure I have it set correctly on the (apache) server side of things. Then I can get more into Zone Editing etc.
I am working on a cluster for a molecular dynamics class and I have to edit my FORTRAN code (only the newest and best for me!). In order to get through to the cluster I have to ssh in. The network on which the cluster resides is behind a firewall, so I have to ssh through the firewall into the network first.
this is fine, I can login and move files and folders as needed, including sftp-ing into host 1, then into the cluster so I can transfer files from cluster to host and then host to me. This gets rather tiresome, so it would be nice to edit the files in place.
The problem is that when I access my code with emacs it launches the emacs client on Host 1, with no mouse support. I know the purists will howl about how I should be using keyboard shortcuts, but I am a chemist and not a programmer, so the mouse is very nice for me. Is there any way I can perhaps mount the cluster using sshfs so that when I open my code it launches a local instance of emacs? Sorry if this is the wrong forum, but I thought it was network related.
I got a bunch of machines (~10) that I share with my co-workers. I have appropriate .ssh file(s) set up so I don't get prompt for password when I try to ssh.Currently I ssh into these hosts and then do a top to check the load before I start using the machine. Because I don't want to be on a busy host.Can someone show me how to write a script that find a least-busy host given a list of hosts to check? (hardcoded is fine)

View 3 Replies View RelatedAt the school i work in i have a server2k3 server that provides a domain to all the windows clients, aswell as a fedora server that acts as an imaging machine and webserver.
Im rather concious of the fact that if for any reason the Server2k3 server was to die there is no backup of active directory, or anything that can take its place whilst a replacement is found.
So is it possible to use a fedora machine with samba as a secondary domain controller? so it can be used as a login server, and has a copy of AD.
The internal network is behind nat done by the PC Router.The TP Link is recieving wireless signal from outdoors and it has switching and basic routing capabilities. I'm using the PC router for better routing options.PC Router (or R for short) is a triple-booting machine - Linux, FreeBSD and Windows. It has two lan cards - external (ext_if) - 100Mbps Realtek 8139 and internal (int_if) - 1Gbps integrated Realtek 8169.The problem is that all traffic from R to the network is slow - about 5-20K, while the traffic in the oppoiste direction is all right - about 10MB that is fine for 100Mbps cables, NICs and switches. The problem persist no matter the OS the pc R is running.I've tried some debugging on the situation as follows:
- put another PC at the place of R - everything is fine. That exclude the possibility of damaged cables, RJ-45s, switches and etc.
- connected both of the NICs to the Internet while the internal network is being disconnected and they both work fine (no delays)
- traffic shaping is not running
- there is nothing in firewalls except NATing the internal network (and it is working fine). Actually these firewall rules have been operational for more than months and everything was fine untill a week or two ago.
- changed the internal NIC with another
- connected the internal network directly to the TP and all of the PCs are getting good network performance. Then connected the R machine to the TP as well and there was good performance between the internal network PCs and R.
- R has good performance to the TP. In fact everything has good performance directly to the TP (when not connecting trough R).
- the problem persist only between R and machines from the internal network.
So here's the setup:
Ubuntu 10.04 host inbound port 22 open
FreeBSD 8.0 host no inbound ports open
Both hosts are running sshd currently. What would you do for the Ubuntu host to be able to ssh to the FreeBSD host? A tunnel?
I have two servers relavant here: mail.domain.com (1.1.1.1) - which is the nameserver and the mail server for domain.com. www.domain.com (2.2.2.2) - which is the www subdomain for domain.com domain.com (cname www.domain.com) - an alias for www.
The zone file for domain.com lists mail.domain.com as the MX server for domain.com. 2.2.2.2 is actually being served web pages as a virtual host. It's real hostname is www.anotherdomain.com. Mail for domain.com works pretty well, in general. However, if I attempt to send mail from www.domain.com (or its alias domain.com), I get "mail for domain.com loops back to myself" in the postfix logs. On 2.2.2.2 /etc/postfix/mail.cf has mydestination = www.anotherdomain.com, localhost. How do I tell postfix on 2.2.2.2 that mail for domain.com needs to be delivered to mail.domain.com?

I was wondering if there is any way to enable an MS Windows client that is otherwise unable of joining a domain to join a domain controlled by (open)SUSE? Is that inability only for joining a Windows based domain but a client that runs XP Home Edition or similar domain- incapable version of Windows could join a domain if it was controlled by Linux?Pardon my newbie style, but answer doesn't have to be detailed step-by-step, just yes/no answer with some pointers would do. I am not new to linux but new to network services... search engines weren't friendly when asked this question at the search bar...

View 3 Replies View RelatedAt work, we run Windows... Windows domain, windows workstations, etc. Today my boss asked me my thoughts on running an Ubuntu lab within the mixture of our existing Windows setup.
Well, that brought several questions to mind. So I understand you can bind an Ubuntu computer to a Windows domain, seems easy enough, whether you do it through Samba or the other guide I read that I kind of forget at the moment, but anyway...
I was just curious how Ubuntu interacts with domain users when on the windows domain. For example, if we have an Ubuntu machine on the Windows domain with a local user "administrator" and that's it, would any domain users be able to log into the Ubuntu work station, similar to how it is on Windows?
