Debian Configuration :: Dhcpd3-server Netboot Installation?
Apr 1, 2011
I am attempting a netboot installation and I aw following the documentation found here My problem is that given my dhcpd.conf I am met with the errors listed below. I have checked to make sure that none of the conditions that the error warns about possible causes are currently in effect on my system.
option domain-name "example.org";
option domain-name-servers ns1.example.org, ns2.example.org;
default-lease-time 600;

I currently got Ubuntu 10.0.4 server edition running on my server. I got 2 network cards in it. One for (eth0) the pppoe connection and the other one (eth1) for dhcp and network.
When i installed dhcpd3 server a couple of days ago, it wouldn't start. So i searched the web and came on the conclusion that i have to do " sudo ifconfig eth1 down sudo ifconfig eth1 up 192.168.0.1"
Problem is i don't have connection with this pc all the time. So if i have to restart it, the dhcp server won't start.

I have been trying to install Ubuntu by network booting, I used tftp in Windows in another pc, and the target boots successfully but fails to download from any archive mirror, I'm not sure what goes wrong.
Well, I'm trying to do is, my friend's HP-mini fails to boot to Windows, and BIOS also gives error-messages, the thing is that my friend has important data on his netbook, it has only one drive, no cd-rom, and it doesn't support USB-booting, so I was thinking if I get to access an Ubuntu, I will be able to backup his data and install Windows, I would use anything that would let me copy files.

I am *finally* getting around to rebuilding my file-sharing computer. I'll be sharing files with both Linux and Windoze machines. It's a home network, so there's nothing fancy needed. I know I have to tweak my smb.conf file until I'm satisfied with the features and security. I'm using SWAT and I'm starting with a bare-bones conf file. It's not secure but I can see the server and selected files/directories from my other Linux box.
My really dumb question is, do I have to reboot both the server and the client machines every time I change the SAMBA configuration? I thought I just had to stop and restart the SAMBA service in the SWAT software - but then the server disappears from my client. It looks like I need to reboot both machines for the client to see the server.

Running on Debian Lenny, installed dhcpd with apt-get install dhcp3-server. Machine has two NICs: 192.168.1.1/24 and 10.100.1.17/24.
My /etc/dhcpd.conf:
DHCPDARGS=eth0
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.100 192.168.1.200;
option routers 192.168.1.1;
[code]....
Trying to start dhcpd reports "no subnet declaration for eth0 (192.168.1.1)" and "no subnet declaration for eth1 (10.100.1.17)". Is dhcpd using /etc/dhcpd.conf, or do I have the wrong config file? If it's right, why is this failing?

I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).

I have dhcpd3 running but it does not seem to properly use my vlan subnets to assign addresses.
I have eth0.10, eth0.20, eth0.30, eth0.40, eth0 all declared with proper ranges, subnets and gateways.
If request an address in on eth0.30, I would think that it should use the range associated with this subnet (ie eth0.30 is 10.10.30.10/24) and this is setup in dhcpd3, but this is not the case.
It seems to use the first declared subnet instead. If I comment the first subnet out, it uses the second one properly.

I'm running the current release of Debian with the 2.6.26-2 kernel. This is an upgrade from an older (2.4 kernel) series redhat release. One of the things I had working in the older system was a dns server with accompanying monthly update of the root hints file. I tried working through a dns how-to to set this up again, but it seems much has moved around since I last played with this. All of the files listed in the how-to are not where it says they should be. I am looking for a better reference on keeping the dns server running with current server information.

I wanted to setup my server as a router/gateway just for educational purposes and also when it succeeded i will keep the gateway and place it on the front line right after my modem.
My current setup as it is now :
The GATEWAY/ROUTER will be doing the main work to act as a dhcp server and firewall.
Now my setup as it is now :
So now what i ment to do was :
Let the clients connect to the gateway via ETH1 and all the stuff being router to ETH0 which is the NIC that is connected to the internet.
But now i have two huge problems :
1. The DHCP configuration seems to be fine the client machines get their ip adresses and /etc/resolve.conf looks fine to. But somehow the GATEWAY/ROUTER wont let me use the specified external DNs server so i cant do anything on these machines.
2. The firewall script [url] at line 27 should be DROP but if i use this line of code the GATEWAY/ROUTER cannot use his dns server settings so when i try to browse the internet or ping a machine outside my local network it would came up with nothing.

I have a bootable usb stick with a Linux utility on it. After poking around for a bit I figured out the boot order:
isolinux.bin <--reads isolinux.cfg
loads the kernel: SA.1
loads initrd: SA.2
then depending on the options you select it boots one of two .iso files I want this utility to netboot instead of booting with a usb stick; is there a way I can package isolinux.bin, isolinux.cfg, the kernel and initramfs, iso's and all the other files on the root of the usb stick into one iso that can be tftp'd to the host which would then boot something that would extract the iso to ramdisk and start booting so that isolinux would run as if all the files were locally stored on CD/usb stick?

I am very interested in using CentOS as a server for diskless PXE booting and was wondering if this was a possibility. I have a working DHCP/TFTP/HTTP system set up and going and I can get my client machine to boot a linux image without any problems. Ideally I would like the diskless machines to be able to immediately load an image through PXE and store their own filesystems on the server through the use of NFS.I heard about system-config-netboot and got very excited because it sounded like something that would help me set up a diskless system. However, after doing some research I have heard from many that it is generally buggy and unlikely to work. When I tried using it I got the error: "The diskless directory must be NFS exported and contain a boot sub-directory"Even though my diskless directory WAS nfs exported and most definitely contained a boot sub-directory. Does anyone have any advice on using this tool, or using CentOS as a server for diskless clients?

I tried to build a HP DL380 today, and the drive wasn't detected. Suspecting hardware issues, I tried it on a 360, same issue. We built these machines before with no problems I used the 8.10 install on our PXE server, and it worked fine. I suspect it's related to the upcoming 8.04.4 release, perhaps a new kernel has been inserted and has missed the cciss driver? Booting using 8.04, and running find /|grep cciss, doesn't find anything. I can't remember the last hp 8.04 build I did, but it was in the last month or so. Doing it with 8.10 finds the driver. (this is the 32 bit install)

I am hoping to find some much needed help here. I have been to various other sites and am beginning to think that I am not meant to have a server of my own.
I was told that OpenSuSE was good for beginners. So far, I am wondering.I am trying to set up a home network ( 2 laptops, 1 desktop. The laptops are wireless )
I'd like to set up a web server to run a personal webpage or two and maybe a forum, shoutcast server and IRC at some point down the road after I figure out the first two.
I found a guide, but it was for 64 bit and wanted me to install ISPConfig 3 ( Which, obviously I don't need )
I would like some basic, beginner help on installation, configuration and whatnot on setting up a web-server and mail server.
Yes. I have a static IP ( leasing an IP block from my ISP ). Yes, they allow me a web-server and mail server ( I had to get the IP block to do so ) and I have my own domain name to use.
On the various attempts, I managed to get apache working. ( When I visit my domain name, it says "IT WORKS!" which is nice and all, but I am use to using Cpanel and have no clue how to setup / edit a website outside of a panel ( or even FTP )
I think I got the mail server installed, but again ( as with the web server ) have no clue how to setup / configure and use it.
I either am using the wrong search words for help or asking incorrectly or something. This is my final stop. I am at the point of just forgetting it, chalking it up to a lost cause.
I do hope someone here is willing to be patient with me and help me through it all. I will even give link backs and Kudos to this site if it all works out.

Debian Jessie on a raspberry pi 2
I'm trying to get nfs server working at boot up and it isn't starting because it says portmapper isn't running. I've read through a bunch of documentation on this and have gotten to the point that if the documentation tells me to Code: Select all$ apt-get install nfs-kernel-server portmap I usually stop there as it is outdated. I cant find a process doc that utilizes rpcbind. So, here is what I've done on my own:
setup /etc/exports with a proper nfs dir and exportfs it
Code: Select all$ apt-get install nfs-common nfs-kernel-server
$ sysv-rc-conf
---│ nfs-kerne$ [ ] [X] [X] [X] [X] [ ] [ ] [ ] │
---│ rpcbind [ ] [X] [X] [X] [X] [ ] [ ] [ ] │
$ service rpcbind start
[Code] ....
The errors however don't seem critical as I'm able to mount the exported directory. OK so it appears to me that nfs server is working. However through a boot, the nfs-kernel-server and the rpcbind services are not starting. The nfs-kernel-server didn't start because rpcbind wasn't running. So I start rpcbind and then nfs-kernel-server and then nfs server works. So what am I missing? Why will rpcbind not start at boot?

I'm having a lot of difficulty trying to use tab completion while working in my FTP server from a terminal.I access this server with other Linux distros and OSX and the completion works fine. I've tried changing a lot of Debian config, but it seems to only affect the completion within the local scope.
Tab completion does work for system related tasks, no problem.
System:
Debian 8.2/Kernel 3.16.0-4-amd64
FTP Server:
Trendnet TS-I300 NAS with FTP/upnp
Settings:
Enabled in bashrc:
Code: Select allif ! shopt -oq posix; then
if [ -f /usr/share/bash-completion/bash_completion ]; then
. /usr/share/bash-completion/bash_completion
elif [ -f /etc/bash_completion ]; then
. /etc/bash_completion

I have ssh and http server running on a linux box.The interface is DHCP configured, using dyndns.org to register its assigned IP, my ADSL modem does not do routing.When i reboot the system none of the servers are visible from the outside...Recently i got a hint to add "ping google.com" to cron run every 5mins. With this hack the servers become visible, and i can see/connect from the outside; - but for obvious reasons ont like this solution.Anyone is able to shed some light why the server needs to do outgoing tarffic to become visible?

I have since a couple of days a vps. I discovered that there's is no nameserver is running.
# host google.com
Nameserver not running
google.com A record not found, try again
Also there's no resolv.config in /etc/. I re-installed the OS several times without any changes. I ask my host about this but he has not answered my questions.

I'm trying to get my simple home web server on the internet but I cannot seem to make it work. I've set up a LAMP stack to host my website and it works perfectly on my local network (accessing from [URL].. but not from the internet. To test it for now before I set up a dynamic dns service, I am trying to access my website via my WAN IP address from within and outside of my home network (ie http://69. When I do this, I get a "taking too long to respond" message, instead of a host not found or 404 or something of that nature. My box has a pentium 4, 2 gigs of ram, and is on a DSL line so I have a hard time believing anything is "taking too long". Here are the software packages I've installed:
-ssh
-apache2
-php5
-mysql
-phpmyadmin
-proftpd
-mediatomb
All of these packages work perfectly fine from within my home LAN, but NONE work outside of my network.
Other configs:
-My router forwards traffic on port 80 to my server
-My iptables allow incoming traffic on port 80
-My ISP, AT&T, does not block port 80 (or any port, according to various online sources)
Perhaps Apache is not configured correctly? What apache config options would be related to this problem?
I've previously tried a similar setup with the dyndns service fully configured (I followed a very thorough guide down to the t - wish I had the link it was excellent), but to no avail - I got the same "too long to respond" accessing from my domain name. I understand that there are a multitude of causes for this problem, so what can I do to narrow down the source? "How to set up a LAMP server" guide, because all of them have lead me to where I am now.

Let me start by saying its a school assignment, and therefore not a real world situation. Nevertheless, I would appreciate any help I can get.The company ProvidIT has contacted us, their website has been hacked. Instead of their normal website, it shows Buy creditcard details online, click here (cc4u.jpg). A classical defacement.The following offenses also might have been committed. So its our job to find evidence for those offences.(I had to translate the Dutch law articles, so they might not be 100% acurate legally speaking, but you get the idea)
- Unlawfully accessing automated systems
- Copy or tap (eavesdrop) data after hacking
- Unlawfully access or use system resources of a 3rd party computer

I have a strange problem. I have set up a server to run without a keyboard, mouse, or video. If I boot it connected to a monitor, there is no issue. However, if I boot it without a monitor attached, the CPU just runs at 100%. Below is a shot of my HTOP from the machine: The weird part is that if you sort the processes by CPU%, they don't actually total 100%. I was trying to see what was pushing the CPU so high, but most of the time the running processes only total between 5 and 20%. Has anyone else seen the problem? Any idea what's happening? I'm worried that if I leave it running like that, the processor could burn up. My temporary work around is to boot it up with a monitor, then disconnect the monitor, but that's really inconvenient.

I have a rented vserver running at Strato [URL]. It came preinstalled with Debian 7. I upgraded it to Debian 8, what seemed to run fine, all services running. The problems came up when I tried to reboot the server to test the init system. It just does not come up, I cannot ping it, nothing. I can boot into the rescue system, mount the system partitions and chroot in to the filesystem. In this state I also can run my services, including apache2 and mysql. In the syslog I find nothing about the reboot. Now I need to reboot ino the normal system. I already tried to resume to sysvinit without success.

I downloaded the most recent version of debian and isntalled it. Everything went really well there. Until i issued free -m on the box. It would appear that the server is missing about 300mb of ram which is okay for i figured perhaps the video card / sound was taking that amount of ram for it'self. it was not until i installed Xen and I found a bigger problem with memory and my system. for what ever reason when I attempt to create a domU with 512mb of ram, i need to add 19MB more ram so that when i issue free -m from within the domU it will show a total of 512. worse yet is that when i raise the total up to 1024 for 1gb or domU ram, i need to addd 28mb or ram. and add 28mb of ram PER GB i wish to add to the domU.

So I'm running proftpd on an old machine just for my own backup purposes, but I'm running out of space. I was wondering if it would be safe/efficent to set up an additional USB hard drive to the LVM drive that I have now? As in, would it write quick enough (USB 2.0), read quick enough and not corrupt data?
