Ubuntu LTS 8.04 + DHCP. Works fine except for fixed addresses. I mean all devices which need to get fixed IP according to their MACs don't get them and keep to receive random IPs from the range (almost everytime all machines receive the same IP they got from DHCP for the first time).
View 2 RepliesUbuntu LTS 8.04 + DHCP. Works fine except for fixed addresses. I mean all devices which need to get fixed IP according to their MACs don't get them and keep to receive random IPs from the range (although almost everytime all machines receive the same IP they got from DHCP for the first time).
The following config was created by Webmin interface.
At the one of the ubuntu forums i was advised to carry host description out of the subnet description.
I have a slackware server running ISC dhcpd and bind, and I want to give a dual boot XP / Ubuntu client a fixed address based on its MAC.
I added a host stanza to my server's dhcpd.conf:
Code:
I restarted bind and dhcpd, restarted the client's networking, and it still requests (and receives) its previously leased address, which is not the fixed address I want it to get. I tried dhclient -r to make the client release the old address, didn't help. On networking restart it still gets offered the old (wrong) address. Could it be that dhcpd somehow hangs on to the old lease even after the client sent a DHCPRELEASE?
How do I tell dhcpd to forget about an old lease, and how do I make dhcpd hand out the fixed address (and only that address) I specified for a given MAC, regardless of what the client requests?
When I install Fedora 10 on a new system, I let it default to DHCP. Later, I change the system to a fixed IP address by running system-config-network, selecting eth0, clicking on "Edit", clicking on "Statically set IP addresses:" and filling in the blanks. Is it possible to accomplish the same thing using commands that could be entered in a script? I assume one of them would be
Code:
ifconfig eth0 address XXX.XXX.XXX.XXX netmask 255.255.255.0
I have DDNS configured and working for dynamic addresses, but it's not quite right for static addresses yet. The DHCP server assigns the static address, but it doesn't update the DNS sever with the associated host name. Which means I have to use the IP address when accessing the host instead of the host name. How can I get the DHCP server to update the DNS with the host name associated with the fixed-address?Here is my current dhcpd.conf.
Code:
ddns-update-style interim;
ignore client-updates;
[code]....
I want to set up a dhcp server such that the clients get same ip every time. Giving fixed address to every client would be a long process.
"I don't want to assign a specific ip to the client but what i want is the server provides same ip every time"
I am running my own Postfix mail server. Some time ago I noticed that most email was rejected because of the server's dynamic IP address. So I got a fixed IP address. However then I noticed that some mails got rejected due to failing the reverse DNS check. So my ISP told me to get a range of IP addresses and they could then create a PTR record for one of those addresses. That is now running but it turns out that the IP address used for the PTR record is a ... dynamic IP address. So Spamhaus PBL rejects my emails again.

View 1 Replies View RelatedFor some time, I've had DSL and used Fixed-IP internally. I moved, no DSL, no cable, no nuthin' but dial-up and flaky cell-phone modem. Ugh. Along comes American Recovery and Reinvestment Act providing funding for making high-speed internet available to those of us in the boonies; no up-front or monthly equipment costs, affordable monthly changes, whoo-boy, that's for me. Installed, works, bada-boom, bada bing.
I have three servers, a network printer and a large format pen plotter that have all happily played together with fixed-IP for years connected via a Linksys BEFSR41 router and CAT-5 or CAT-6 cables and I do not want to screw around with DHCP (and the printer and plotter don't particularly like DHCP in any event). The servers talk to each other with SSH, their names and addresses are in /etc/host and all has been well with the world. DSL connected with PPPoE, HughesNet connects "automatically" to the modem with DHCP. I also have a switch available for additional LAN stuff as needed. Of course I had to do a hard reset of the router when setting up HugheNet (right back to infancy).
I do need to have DHCP enabled in the router for the limited occasions that a Winders thing gets connected to it (not my box, I don't mess with it).
Now, the actual question: is there any setting in the router that will enable fixed-IP, ignore DHCP leases unless the server is running DHCP (like a Winders box) and not bother me with screwy lease addresses that override my fixed-IP addresses? My servers are running Slackware 13.1, all configured with fixed-IP, all configured to "know" each other via /etc/hosts, /etc/resolv.conf has DNS Server address in it (and DHCP is not permitted to overwrite /etc/resolv.conf.
Assume I installed originally CentOS Desktop with IP receiving from DHCP server.Later I decided to assign a fixed IP to the local CentOS installation.How do I switch (permanently) the dynamic DHCP IP assignment to a fixed IP?
View 1 Replies View RelatedI am puzzled with trying to configure a linux (openSUSE) client to dhcp to eBox DHCP server. I am using dhclient to lease an IP address with dhclient eth0 -s 10.45.48.108 and get a response
openSUSE11232CL1 dhclient: DHCPDISCOVER on eth0 to 10.45.48.108 port 67 interval 4

openSUSE11232CL1 dhclient: send_packet: Network is unreachable
openSUSE11232CL1 dhclient: send_packet: please consult README file regarding broadcast address.
The server reports eBox141 dhcpd: DHCPDISCOVER from 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
eBox141 dhcpd: DHCPOFFER on 10.45.200.2 to 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
I interpret this as the server receives the request and the client accepting it but the lease does not last long and the connection breaks. what this could be and why the connection breaks? Or my undestanding is totally wrong on how it works and should work? And BTW, where is that README file that's referenced in the message I receive on the client?
Version 10.04 LTS. Installed desktop version and network worked but I needed a static IP address and the install configures for a DHCP configured address. I tried changing to static address using the System->Preferences->Network Connections application but was unable to get the system to come up with the network up.
So I manually modified the /etc/network/interfaces and the /etc/resolv.conf files. I restart the system but when I do an ifconfig, I don't see a configured IP address on eth0 (only the loopback address). If I run /sbin/ifup eth0 everything then works fine and ifconfig shows the correct address bound to eth0.
My files are as follows:
I'm running Ubuntu 10.10 and I'm having problems trying to assign it a static IP address. No matter what I put in the Preferences->Networking area (identifying the interface as Manual)... it still will query DHCP for an address if I run the dhclient command. I'm using to using ubuntu server where I just set the IP in the interfaces config file.
View 1 Replies View RelatedI am new to Linux so thought it would be a good learning exercise to try and setup an FTP server using linux.I have downloaded and installed Ubuntu 10 server edition and installed vsftpd, following instructions found on here I have configured the software and I can connect from an FTP client on my windows PC across the internal LAN.I have a couple of questions if I may:
1) a post on this forum suggests that local users can access the FTP server if the correct line is enabled in vsftpd.conf - I have done this and the fact that I can access it shows this is working I would think, however users added subsequently with the useradd command cannot access the server. Filezilla shows a could not connect to server error.
2) how do I give the server a fixed IPv4 address? It is currently using DHCP
3) I need to be able to put files into users folders for them to access offsite, but I don't want them to see each others filesfolders, can I do this?
I'm building up a server based on 8.04 LTS. It's using OpenVZ, and as part of that it creates a virtual network interface venet0. I add a stanza to /etc/network/interfaces that looks like this:
Code:
allow-hotplug venet0
iface venet0 inet static
address 10.53.35.1
netmask 255.255.255.0
[Code].....
Looking further, I note that /etc/init.d/networking is not symlinked into anything other than the rcS.d directory. It's been a while since I've been tinkering at this level, but I understand that there should be a symlink from rc2.d/Sxxnetworking into ../etc/init.d/networking. So I wonder where eth0 is getting configured.
how to make a Ubuntu 10.04 server VM look for an IPv4 address if it doesn't seem to by default?

View 2 Replies View RelatedI 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.
View 4 Replies View Related5.10 Breezy configured as machine controller. Works great eth0 is a fixed IP to communicate with controller comms board. Not easy at all to alter - the comms board is hard coded to listen on eth0 for commands.
I can use eth1 as the default gateway and ping google.com, etc. But when I now attempt to communicate with the controller with netcat, e.g.
Code: echo !HH | nc 192.168.1.6 80
I obviously never get an answer since the request is passed via eth1. Using the -g option with netcat doesn't work either. I had a look at iptables but it doesn't seem to be able to do what I want. How I can still use eth0 as my communication port to the controller whilst eth1 is the default gateway?
I am trying to set up an unused machine as a web server for my students.
I originaly tried with Redhat 9 and had the same problems. I am using an HP Pentium 4 system with 2 network cards.
1) The built in Realtek RTL8139 configured as eth0.
2) An add in Broadcom BCM5782 Gigabit card that was added I presume when the built in card failed (we have a number of machines like this around the school), configured as eth1.
I did not realize the second card was installed when I had Red hat 9 on the system, but I discovered it after installing centos 5.5. I have tried to configure the system to use DHCP with and without getting the DNS from the provider, and both ways the system complains that there is no connection, check the cable, so it will not activate the device.
When I configure the device to use a fixed IP, I can configure the device, but I can't ping anything on the network other than myself. I suppose it is possible that both network cards have failed, but I get green link lights with both cards, when I connect them to my router, so I am at a loss as to why neither board seems to work. I don't have a spare network card to slide in because the computer takes a special mini card. Is there an easy way to test the board to see if the board is a problem?

View 2 Replies View RelatedI found a strange problem when I use gdb in eclipse to debug. When I step in the program, the register RIP(I'm using x86_64 machine and that's EIP in 32 bit mode) shows correctly but the line stepping in the source code may be far from the correct line. For example, when there is no loop in the source code, the RIP keeps on increasing and the current instruction pointer goes back to several lines back. I'm sure the source code is the right one because I when I checked the memory and local variables after several lines the values are all correct. The source code has many empty lines and does it matters with GDB?

View 1 Replies View RelatedEver need to provide access to multiple PC's and did not have a router only a hub. Maybe this isn't original thinking, but then again maybe you didn't think of doing it this way (which i am sure there are many ways to do it) So I have 2 Ubuntu Servers, 1 Windows Box and a Hub - All 3 with internet access off of single ip and single Ethernet port.
While searching for a backup method today I came across Clonezilla. I was wondering if this was the right thing for me and since I needed to backup my roommates PC for a reformat and install of Windows I decided I would give it a try, but only if it would work. I didn't want the hassle of going into the main part of the house and finding out what cord was what as there is a cable modem connected into a switch (4 static IP's with internet) and one port of the switch hooked to a router) Anyways, didn't work he was on the router I was on the switch)
But this got me thinking. When I setup my server to do this, during one of the setup scripts it said it was setting up Internet access for client machines and that it was assigning them IP addresses threw a DHCP server that it had installed.
So, I dug up the hub connected the internet cable to hub up link and Server 1 on port 1 Server 2 on port 2 and Windows on port 3 The main server gets the internet provided IP address and routes it to the hub via a virtual interface. Server 2 is configured for DHCP and the windows box, It was set to get info automatically but it didn't fill the DNS info so I had to manually do that (just a heads up) I decided to use OpenDNS Servers (208.67.222.222 & 208.67.220.220) but im sure putting in the gateway IP address would have worked too.
So, by now if you need this I am sure you are excited and want to get to it. Like i said there are probably other ways of doing it, ways that don't involve you installing clonezilla and DRBL, maybe even just DRBL is needed, maybe one of them installed whats needed as a dependency- all I know is it works, if you know - elaborate so people know, but hey- this way not only do you have internet access on all PC's you can deploy custom images to them as well.
This works on my Slackware64 13.1 using KDE 4.4.4, Conky version 1.8.0. This is a simple .conkyrc tweak that doesn't need feh, it doesn't have the distracting faun shadow-border and most importantly, it doesn't disappear when you click your desktop (On my system anyway). These are the relevant sections to edit:
Code:
own_window_colour black
own_window_hints undecorated,below,sticky,skip_taskbar,skip_pager
own_window_transparent yes
own_window_argb_130
own_window_type override
own_window yes
I found that getting rid of the own_window_argb_values yes suggested in other fixes and replacing it with a specific alpha and then changing window type to override solved all my issues. I've noticed no bugs or strange happenings. This seems to be a common problem with a lot of workaround solutions. I think this is a much more elegant way. Edit: Not persistant... After 2 reboots it's back to normal.
