Fedora Servers :: Configure DNS Server For Small Network
Jul 2, 2010
How to configure DNS server for my small network. In Fedora Linux operating system I want to use Linux as a DNS server for my small office. there are files " /etc/hosts" and "/etc/resolv.conf ".
what is the purpose of these files and in which situation we use these files? For configuring a new DNS server. how can i configure my own DNS server for my small office? Any blog or site in which they show steps to configure DNS server.
Small office... 20-30 computers all windows based. xp/vista/windows 7. 3 Servers running ubuntu 10.04... 1 domain controller, and two file servers with samba. We want to be able to login once in the morning, and then not have to worry about users/passwords at all throughout the day. So I was thinking that I could setup a PDC and then make the two filservers both BDC's and use ldap to authenticate everything. Would this even work out? and is there a better way to do it?
I am planning to deploy an OpenLDAP server in my LAN for basic authentication, but I have no idea how to do it. I would like to know how to configure an OpenLDAP Server, and I would also like to know about knowledge resources, if any.
I want to configure squid server with SSL so that users send clear text username/password and also data in encrypted mode. i googled but all of the configuration is for reverse proxy not requests from users to proxy server in LAN for example.
i got an old server with a 64mb flash-disk in.this seems to be the boot-disk.would it be possible to get ubuntu server on this?there is also an ide-disk in.in my opinion it should be good to boot of the flash disk and put the /home or /srv on the ide disk.someone any ideas about this?
I am going to try and replace our crappy Windows/imail server with a new ubuntu 10.04 LTS based machine. It will end up with about 400 domains on it with around 3000 users total. 96% of the domains have very light use. 4% of the domains have heavy use but do not send any bulk mail.
Can someone here recommend a mail server software package that would be easy to administrate and easy to backup/replicate? All we need is POP with webmail. We do not need IMAP or want any group/collaborative functions.
What do you usually use for anti-spam on a linux mail server? We want to keep it all open source if possible.
For hardware we are looking at an HP DL360 G5 with dual Xeons, 4G of ram, and the P400 controller with 6 SAS 15k drives. Do you think a server like this will be able to handle the mail on linux? Volume is around 400k messages a day inbound with about 10% being legit/90% being spam. The server will be dedicated to mail hosting and will not host websites.
I'm looking for a program that I can use to keep track of how much bandwidth goes to the various computers in my small network.All of the bandwidth goes through my squid server, so the easiest would be to just have a program that can accurately analyze the squid logs and tell me how much bandwidth is going to the different computers.I've tried both "bandwidthd" and "calamaris" I can't figure out how to get either one to actually do anything in Ubuntu.
I am trying to setup a file server for a small office but have hit a couple of hurdles, is there a step by step guide how to setup a network for windows and mac computers to use it? I had setup a share etc but once I restarted the server all the files disappeared which I had in the home folder? Also when I setup users how can I use passwords that I select as everytime I set one it encrypts it and uses that instead of my one?
I installed it on very old machine P3 1200Mhz and it works ok but I have problem with text mode because I have 75x132 aprocs. text on screen and I don't see what I type or system replay. Is there simple way to change to 25x80 or something with greater letters. I don't have GDI.Someone sad to me to do:sudo dpkg-reconfigure console-setupand it's does the job but when I restart system it's gone.
I've installed the Ubuntu 10.04 Server onto a PPC G4 Mac just for the experience of setting up a server. During the installation process Ubuntu couldn't auto-configure my DHCP Network. I'm using the airport card on a wireless network. How can I manually configure the network once Ubuntu is installed.
I just finished getting a semi-old desktop computer up and running with ubuntu server edition. It's running subversion and samba for my office of 5 people. I was wondering if there was a simple online/cloud based backup service to automatically back up my subversion repository and samba shares in case of any hardware problems?
I have a lab of 10 computers with ips from 192.168.1.120 to 192.168.1.130 the server's Ip is 192.168.1.116When I am on client computer I type the server's Ip address on the browser and it works. All i want is that instead of entering my servers Ip I could just enter an address like: example.lan
I'm trying to setup a Samba network share with a Fedora Directory Server backend. This will be used primarily for Windows users to authenticate before accessing the share. I am using Fedora Core 10 and have all of the latest updates installed. When I try to connect from a Windows machine, I am prompted for a username and password. I enter the username and password of the account I created in Fedora Directory Server in OU=People. The credentials are rejected. At the same time in the log file I see this:
[2009/02/24 16:50:16, 3] auth/auth_sam.c:check_sam_security(282) check_sam_security: Couldn't find user 'Administrator' in passdb. [2009/02/24 16:50:16, 2] auth/auth.c:check_ntlm_password(318) check_ntlm_password: Authentication for user [Administrator] -> [Administrator] FAILED with error NT_STATUS_NO_SUCH_USER
Administrator is the user I created in Fedora Directory Server. If I perform an ldapsearch it will find the user as uid: Administrator so I know it is able to be looked up in FDS. But I'm guessing that's not the problem.
My organization is running a VMware vSphere based platform. On top of that we have a Sun Gridengine cluster consists of a number of ubuntu VMs.At the moment, we deploy new cluster nodes from the VM template. Although it already saves us lots of time, we still need to configure the network, host name, register DNS record manually.In a near future, we will need to add 100+ more hosts to the cluster. So we are seeking a automated deployment so that a VM does the following during its first boot:
1)configure the network for the correct IP with DHCP or manual.
2)request a designate host name (maybe from a pre-defined datasource?) and configure host name.
3)register itself to our DNS servers.
We don't really have experiences for running big cluster. So welcome to share your opinions and experiences.Specially I'd very keen to find out if there is any well-proven solution right there or I will need to implement from the scratch.
make deb package with samll project of php and myysql database such as login.php, index.php controll.php etc and database_name.sql. when i install this deb package my php script folder should go in /var/www file and databse should create automatically. i edit the control file of deb package , in depends line i set apache2, php and mysql because these three thing are necessary to run my script till here it is ok .but i am not able to send my project in /var/www and configure database automatically . i think for this i have to write .sh file but i dont know bash scripting
I've been running denyhosts on Ubuntu 8.04 servers without any problems using the how-to found hereow that I have a new Ubuntu 10.04 server running, I thought I would just install denyhosts from the Ubuntu repository not realizing that the paths and filenames of the install are different from the how-to I am used to using.I figured out what the name of the new denyhosts config file is (at least new to me) and the new location, but I'm not sure about the "allowed-hosts" config file.Does anybody know where the new path for this file is and whether the filename is still the same?
I have used for a long time Filezilla FTP Server on a windows server, for multiple users in my company around the country.Lately the windows box died and I said let's try ubuntu server 9.10. I configured to my best as a Samba file server and from a speed point of view it works even faster than the Winbox.Now getting to FTP setup, I had the following problem when setting vsftpd.How can I enable more directories for the user, each with its own rights. By example, in Filezilla I had two folders for each user: one was a specific folder in which he could also write, and the other was read-only. They were setup with aliases, so that when user login, he sees one continous list of folders.I tried with symlink, but couldn't do it. Also I searched through the man page but also did not find something specific for this task I would appreciate any help you guys could give me in order to solve this issue, using the best practice for vsftpd. Also note that I am open to other FTP servers as well.
I've tried to configure DRBL server to use Clonezilla and that is required me to setup DHCP, TFTP servers.But I've gotten a lot of errors from them - so please look at my attachments from /var/log/messages and dhcpd.conf - help me to find out what are wrong with them.
finnaly i can run my ubuntu server 9.04 well, thnx to this great member of ubuntuforums.org now, i wanna i wannna install SNMP on my system, but after i do that, when i wanna connect with another client, it give me error like this :
Code: no response received SNMPv1_Session (remote host: "10.100.7.179" [10.100.7.179].161) community: "public" request ID: 862383236 PDU bufsize: 8000 bytes
[Code]...
10.100.7.179 is my client, i allready install snmp agent on it. but why still eror then? plz give some help. thnx before
Starting with Ubuntu Server 9.04, when I log in at times the OS smartly reports the number of updates available. I have a couple of questions of how to extend this functionality:
1) How could I back-port that functionality to 8.04 servers? Does that happen somewhere in the /etc/cron.daily/apt script? (Just the checking on # of packages needing updates, does not need to appear on the login screen.)
2) Then with that information, if the number >0 then use mailx to send admins an email. Since 9.04 and higher already do the first item, then in my mind #2 is the only thing needed for 9.04 and higher servers, and #1 is also needed for 8.04 boxes.
I've recently migrated my office PCs to ubuntu. My server doesn't server any big purpose but to provide Internet Connection to the rest of the nodes. Things were quite easier during the windows era using ICS.
Even in Ubuntu we were able to do it using the "shared network" option, simple & straight forward. But things got complicated only after installing "squid". Needless to say it brought in a lot of add ons as far as the http proxy serving is concerned & we are enjoying a better internet(http only) connectivity without any doubt. But we are not able to use our email clients, MS Outlook or Thunderbird
But to best of my knowledge squid strictly is a http proxy hence doesn't support handling requests on ports other than 80. (465 & 995 in my case)
Now I have two queries, 1. Can "Squid" really be used to do what I want here??? using iptables, port forwarding or any other mean & 2. Can any one suggest a good pop3/imap proxy as good as squid is.
I have installed a linux server in my office to run 16 machines. Its main use will be a internal mail server but will be also running websites.
I have installed Ubuntu 9.10 server x64 and have got apache running.
I am looking for the simplest more robust solution for smtp, pop3 and imap. I have only ever used qmail before and found it a pain to configure and its getting old so I though I should probably try something new. I have not much experience with running pop3 or imap on linux so would love a suggestion on that.
I'm trying configure my server for routing between vlans, but I'm having troubles with my server after that vlans are set. I can create vlans and routing is OK, but when I trying remove a vlan, restart the network script or restart the server, the CLI freeze and then I can't do anything. Even Ctrl+C or Ctrl+Z isn't work. I can use other terminal or do other SSH connection (if the network interface used by ssh isn't crashed), but if I try use a ifconfig per example, crash again. The unique solution is restart the server. Nothing about this is found in the log.
How could I configure Ubuntu to be setup as follows...
Wireless Client ----> Wireless Router ----> Home Server ----> Internet
What is needed to make all of the wireless traffic go to my internet connection port. I will be having two ethernet cables plugged into the system one from the wireless router and one to my internet router.
