Ubuntu Servers :: DHCP Server And DHCP Client Simultaneously?
Aug 4, 2010I 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.

Mar 12, 2010Does anyone know the trick to getting Logwatch to make its entries a little less chatty and leave out the "Detailed" section of the Postfix report? I can't seem to tone it down and the daily reports I get include every recipient, host, etc., which is too much info to make a summary report useful.The first portion I get looks like this:
****** Summary *************************************************
9 *Warning: Pre-queue content-filter connection overload
2 SASL authentication failed
432 Miscellaneous warnings[code]....
This would be fine for a quick review that I do first thing. However,the "Detailed" portion that follows is over 2,800 lines long!

May 9, 2010Gidday, for some reason some of my RHEL servers don't send out a daily logwatch email (most do, but two don't) - and sadly I have no idea how to troubleshoot this.
Can anybody give some help/hints as to where/how I may troubleshoot this. I should add that these servers can/do send emails (I have some cronjobs that fire off emails upon completion of their jobs, so I know its not a sendmail config issue).
Ubuntu Servers :: Logwatch Emails Not Sent If Named Logs Are Included?
Jun 15, 2011I've suddenly stopped getting emails from logwatch which runs on an Ubuntu server daily using cron.After a good day or so of troubleshooting, I was able to establish that it was the 'Service = named' line in my logwatch.conf file, which was stopping the emails from coming through. If I commented out this line, the logwatch emails come through with no issues, uncomment, and I don't get an email. I don't get any error from logwatch itself when I run it, even with '--debug high', leading me to think that my email configuration is setup ok, at least. Furthermore, I tried running logwatch with '--output file --format html' and logwatch produces a valid html file.
I then thought: "Could I have a entry in my Bind/named log files which could be rejected by my ISP's smtp server?". So, (to the best of my knowledge) I cleared out the log files in /var/log that contained messages from named. I then ran logwatch (including the named service in my logwatch.conf file) and I got an email through, with a pretty much empty named section, which is exactly what I anticipated. Great! - it's fixed.
So, the cron.daily ran early this morning, but still no email in my inbox when I got up. I then tried to run 'logwatch --Range today' and lo and behold, I got a logwatch report email, which included a named section, with log entries in there. So it seems that something that's been logged by named overnight to my logfiles (i.e. '--Range yesterday') has caused issues again with logwatch's ability to send reports through my ISP's smtp servers.

Ubuntu Servers :: Windows DHCP Server - Multiple Boot Servers ?
Apr 1, 2011I'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?
Fedora Servers :: Build A F12 Cluster To Run DHCP On Top Of Two Servers Using Pacemaker And Drbd?
Apr 28, 2010I'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 :

Ubuntu Servers :: Unable To Get IP From The Dhcp?
May 1, 2011I am setting up dhcp server for my public library and need to divide clients into a number of pools on the same network. The different ranges will be for different filtering requirements via squid/dansguard proxy. I have inhouse clients: staff, adult patron, and child patron, that have different filtering requirements and wireless guests that I want to shorter lease times to handle the rapid turnover rate. Trying to understand the terse manual, you assign pools via allow/deny members of classes, but classes are assigned by matching on mac address or vendor ids. Unfortunately as a poor rural library we have a hodge-podge of hardware with no matchable pattern. So I can solve the inhouse clients by using fixed-address, and remove them from the dynamic pool. Now the dhcp server would be serving only the short term wireless guests from the pool.
A common problem at libraries, you always get a few that are compelled to misbehave and break the libraries TOS. In the past the librarians would kick the offenders out of the library only to have them link in from the step or parking lot. Since I have their mac address in their initial lease I would like to prevent them from reestablishing a connection when they are banned.
My thinking is this; the library's computers are static and not part of the pool, the wireless clients would be unknown-clients, so set the pool to allow only unknown-clients, and for the "bad-boys" add their hosts in a group directive would make them "known" and therefore unable to get a IP from the dhcp server.
group {
host banned1 { hardware ethernet 00:00:00:00:00:01; }
host banned2 { hardware ethernet 00:00:00:95:a6:c1; }
host banned3 { hardware ethernet 0c:f1:b6:fe:00:01; }
}

View 9 Replies View RelatedUbuntu Servers :: Dnsmasq DHCP Nor DNS Working?
Jun 11, 2010I have been rtying for a couple of days now to set up a local dns/dhcp server with dnsmasq on a ubunut server 10.04 I followed the basic instructions from several websites, starting with the ubuntu community one, didnt work, then tried some other, and nothing.
In the server the dns works, i test with dig example.com and i can see the time difference, so dns is working. so the problem is not making the dns work but to make the server listen for dns and dhcp resquests and respond to them.
I have desactivated the dhcp from the router so thats not the problem. making a windows box ping the server works, so the network is configured correctly.
dnsmaq is listed as "LISTEN" on netstat, i read in some blog that it should be using ports 67 and 68 but those are no listed, neither i configured them in any moments, none of the instructions i followed mentioned sth about that. i even tried configuring the window box with the ips and dns accordingly and that wouldnt work either.
so in conclusin i have dnsmasq that does have dns set up but wont answer to any requests of either DNS nor DHCP.
Ubuntu Servers :: DHCP And Static IP's Dual NIC's?
Aug 28, 2010I'm have a number of ubuntu servers that all have dual nics.One interface is used to assign a static public ip and the other is used to assign a static internal IP that can be used on the internal network.The interfaces pull IP's from completely separate gateways on different networks.The problem I face now it that our internal network is moving everything to DHCP on the internal side.I can configure my /etc/network/interfaces so that I can get a public static Ip and a private DCHP, but the problem is that the public IP no longer functions for any services.here is an example of my interfaces
Code:
# The primary network interface

Ubuntu Servers :: Install On A Non-DHCP Network?
Feb 8, 2011I'm trying to install Ubuntu server on an older 05-06 Desktop (IBM) and when I get to the Configuration part it stops right around 95% and the prompt reads that configuration failed do to the fact that my unit is running a non DHCP Network or my machine is two slow. Now it does only have 1 gig in it right now so I'm thinking that might be the problem also. But if it is a DHCP issue how can I install UBUNTU or is it even possible?

Ubuntu Servers :: Installing LTSP When Using A Separate DHCP And TFTP?
Mar 17, 2010I want to install Ubuntu LTSP on top of an already existing system. However, I want to use a different DHCP and TFTP server. Do I simply just install 'ltsp-server-standalone' with apt and run 'sudo ltsp-build-client', stop the DHCP and TFTP server and stop them from starting automatically? Would I then just copy over the pxelinux.cfg/default file from /var/lib/tftpboot along with the initrd.img and vmlinuz images to the TFTP server?
Edit: Do I need to actually copy the whole /var/lib/tftpboot/ltsp directory over to the TFTP server?

Ubuntu Servers :: Trigger A Shell Script Upon DHCP Request?
May 13, 2011Is there a way trigger a shell script after my DHCP server successfully gives out, either a specific IP address or to a specific MAC address.I have two Xbox360's in my house that both receive IP address via DHCP reservations from the Ubuntu server.I have come to accept that without having two public IP addresses getting both to have an open NAT will be very difficult. I have decided that I am OK with only one being able to have an Open NAT at a time, but I want to change the firewall rules according to which Xbox 360 turned on first. This way I can move between level in my house and play online without having to modify rules manually.
