I have a small office setup all on public ips and was trying to work out the best way to move the wearhouse computers on to private ips and leave offices on public ips I have server with 2 nics and i have two switches What i am after is how to set it up so all computers can still see each other but private can not access net All the office computers via switch 1 Public IPs All the wearhouse computers via switch 2 Private IPs
1 DHCP server
3 Routers from ISPs going to switch one
Both switches going to DHCP Server
Ive tried on multiple occasions to setup a dhcp server, but all the google searches return legitimate results it seems, and ill set everything up, except the last few instructions i have to configure /etc/dhcp3/dhcpd.conf and /etc/default/dhcp3-server, but ubuntu says its not there.Im running Ubuntu Server 11.04 and using nano to edit files
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.
Does anyone have a link to a tutorial on how to set up a DHCP server and SAMBA as a windows domain controller? I can't really find good detailed guides by searching google.
I just got DHCP working, but I need to add a "Pre-Defined Option" for the Cisco VoIP network here. At least that's what it's called in Windows. This "Pre-defined Option 150" is necessary on Windows dhcp servers tied to Cisco VoIP networks, but I have no idea where to start getting that set up in Fedora.
I decided to forgo my router's DHCP capabilites and try to make a random computer at my home take on the job.
First of all here's my network topology:
I have a cable modem hooked up to eth0 on my linux box, and this is where my internet comes from and works fine.
I also have another ethernet, eth1, which is connected to a wireless router in bridge mode. My end goal is to have my linux box sit between my internal network and the outside world. Thus it will need to act as a DHCP server, a NAT and as a firewall. Right now I'm just focused on the DHCP part.
Here is a copy of my dhcpd.conf file:
My /etc/sysconfig/dhcpd file has:
However the issue is that it is still listening on eth0. and not issuing any leases on my internal network.
What I think is happening is that it's not recognizing the 10.0.1.x subnet because my router is issuing leases on the 169.254.193.x, even though I put it on bridge mode. But I could be totally off mark.
Also running tcpdump on eth1, I can see requests coming in for dhcp, but my server isn't responding to them.
is it possible to setup a DHCP server using the loopback or a virtual interface? I installed Sun VirtualBox on my fedora system and want to try and kickstart them from within the same box on a virtual network. Is this possible and has anyone done it? I only have a single NIC in the box and it is on my public network.
I have an embedded device for which I've created an html configuration page. This page allows you to set static IPs, dhcp, and can scan for wireless devices.My problem is that in order to access the device it requires that it runs as a dhcp server otherwise people are not assigned an IP and so can not access the embedded devices static IP. (This config page is for the laymen and so they are not the type who are able to set up their own static IPs). One of the potential options is to have the device connect to the network on eth0 acting as a dhcp client. However this prevents me from running a dhcp server.One solution I can think of is running a dhcp server only if it doesn't detect another dhcp server running on the network.
This dhcp server is configured with redhat enterprise edition. I found that logs are generating in the following path /var/log my doubt is how can i setup the logs generating for a specified day.
In my instructions for LAN boot, I am up to the next step :"You need the DHCP server software. If your distribution has none then you can use dhcp-3.1.3 and compile it."ok, so in F11 Live USB . . . I have downloaded and extracted files - they are still in Download directory . . .
Code: [root@localhost Download]# dir dhcp-3.1.3 dhcp-3.1.3.tar.gz
I am trying to set up a DHCP server for a network that does not go on the Internet using fedora 14. I have tried several site and every one I look at has a different dhcpd.conf file. I have tried many and every time I try to start the service they fail. Like I said it does not go on the Internet. No matter what I do when I try to start the dhcpd service it fails code...
Now when I try to pull an Ip from the 96.63.0.0/24 subnet I do not see the options in the DHCPACK from the server. The client gets an IP 96.63.0.12 but no options are present in the DHCPACK or any other DHCP transaction. I have confirmed this trhough tcpdumps on the server and client.
The server version I am using is:
The version of the DHCP server is :
Internet Systems Consortium DHCP Server V3.0.6-Fedora
i have a homework where i have to set up a dhcp server on linux. I am using ubuntu. I tried following: [URL] However after running "sudo apt-get install dhcp3-server" the file "/etc/default/dhcp3-server" does not appear.
Is it possible to setup dhcp server in such a way that even if a client disconnects for a short period of time (5 - 10 minutes) the dhcp server keeps that address for that specific client and lease it back. Tracking can be done using the mac address of the client.
I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received: Login to your windows server and load the DHCP configuration screen Create a DHCP reservation for the MAC address you obtained Add the configuration options below to enable the machine to boot from the LTSP server 017 Root Path: /opt/ltsp/i386 066 Boot Server Host Name: <ip address> 067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'
From: [url]
I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?
i have been searching ways to setup an ftp server. but it seems, everything i tried does not work or not what i wanted.how to setup an ftp server, allowing only permitted users. I'm using the desktop edition live cd.
I've set up a very simple net with a dhcp + dns server using dnsmasq. It works but the server itself cant resolv clients names. Clients do resolv without any problem my /etc/dnsmasq.conf
You are running tftpd as an on demand server i.e. it is only fired up when it is needed. Services run by xinetd are always run on demand. Have you actually tested if tftp on another system can access your PC i.e.
As I do not want to entrust my firefox data Mozilla's Server and have a server runnig anyway, I wanted to setup a server which provides weave service. I found this and know from different sources of the web that this indeed works: [URL] It is a stripped down Weave server intended for personal use. All in all, it does not sound to complicated. The developer says

You ll need a relatively recent php with sqlite, mbstring and json support, and apache, preferably running ssl. Give it a shot and let me know how it worked for you in the comments. I have Fedora 14. Only problem is that Fedora does not provide a php-sqlite package. For this I found a repo [URL] So I installed php-sqlite (as well as php-pdo, php-cli and php common) with
Code:
yum --enablerepo=remi intstall php-sqlite
In consequense all php releted stuff was replayed by remi provided packages. In addition I installed json to get JSON support. The author describes the setup quite easy as follow:

SERVER SETUP
Add the following line to your apache config:
Alias /weave /<path to this folder>/index.php
Restart your apache server. Point your browser at h[URL]. Enter "blah" for the username and garbage for the pwd. Auth will fail, but it will create the db (you can cancel the subsequent request for auth). You should now see a file called weave_db in the directory.
You can create and delete users by running the create_user script.
CLIENT SETUP
in about.config, set extensions.weave.serverURL to [URL] You can run it under http, but this is insecure and not recommended.If I disable or set SELinux to permissive mode I can point my browser to [URL] Here starts the trouble. After attemping to login no weave_db is created. I tried even 777 permission in that directory. I can run the create_user script with php and add a user, but the database does not seem to be recognized, I am unable to login into weave service.
I have had no problem installing Fedora OS on any of my Dell servers prior to this post. Anyway, I wouldn't call this a problem but recently, we bought another DELL server with Quad Core, 4GB, etc... AND this model has 2 swappable SAS Harddrives.
I wouldn't call myself an expert but then again I am not a newbie too. However, I have never setup any RAID before and now I am forced to setup RAID1 on this server. So, in a way, I am a newbie in setting up RAID
Would someone please point me in the right direction as I have no idea what I am supposed to do to setup the RAID. FYI, I will be installing Fedora 10 64bit on this server. I would appreciate if you can start from the very beginning, ie. partitioning, formatting the harddrives during OS installation, etc..
I'm trying to build a Fedora 12 cluster to run DHCP on top of two servers using pacemaker and drbd. The pacemaker runs great but i'm having the hardest time getting DRBD installed.
My kernel version is 2.6.32.11-99.fc12.i686.PAE First i tried to [root@dhcp-primary drbd]#yum install drbd this doesn't give me everything because apparently the kernel module for DRBD must be built from source. so i unpacked drbd-8.3.6.tar.gz and tried :
[Code]...
I'm not very experienced in compiling from source i'd love to make an rpm for this but after scouring the web and trying different install methods, I am still at a loss.
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.
I have a ClarkConnect (CentOS based) box running as my home router on a RR connection. I had the DNS servers set up to use Google's DNS server. I want to change them back to the local DNS servers but I can't find an obvious/easy way to get those address short of a) reconfiguring the router's network to DHCP them (would rather not interrupt everyone) or b) calling their tech support (kill me now!). Is there a command line tool/command I can use to query the DHCP server on the external NIC to see what DNS servers it would set me up with w/o munging my existing setup?
i have a lucid server box running a dhcp server and webmin.i want to bridge openvpn to the network that the dhcp server serves.all the configurations ive seen, id essentially have to install openvpn onto a computer underneath the dhcp server to accomplish this.
