Ubuntu Installation :: Error: "Network Autoconfiguration Failed. Your Network Is Probably Not Using The DHCP Protocol
May 21, 2011
I recently purchased a Dell Vostro v130 which came with Win 7 pre-loaded. I've been using it for a few weeks with no problems, but now I'd like to install ubuntu studio. I made it through the the partitioning part but now I'm getting a networking error: "Network autoconfiguration failed. Your network is probably not using the DHCP protocol. Alternatively, the DHCP server may be slow or some network hardware is not working properly."
I've been using the wireless connection in win 7 without any problem so I don't know why I'm having a problem now.

I am totally new to Linux and have just installed ubuntu 10.10. After configuring the network interface via dhcp I started getting these messages that come in so frequently I can't configure anything else.
[87.186415] Stack:
Why I am getting this messages and more importantly how do I get rid of them.
The installation is on a VM on Hyper-V.

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.

Why trying to avoid ranting about my Linksys router, I'll try and keep things short. I have a Linksys router in which the default firmware was terrible and would not correctly renew its DHCP lease. After getting feed up with that I flashed dd-wrt on the router and now it works better but randomly DNS queries would stop being resolved. To rule out the chances that it is my ISPs DNS servers I switched my DNS to openDNS, same problem happens (although I have to admit openDNS is a lot better than what my ISP has).
Anyways I'm about feed up with it and about an inch away from drop kicking the thing out my window. To avoid that I figured I will give it one more change and instead of using my Linksys as my network gateway I'll move all of that to my home server, and make the Linksys just an wireless AP. Besides setting up DHCP, DNS, and iptables on the server is there anything else I will need to know and setup on the server to make this work?
Side note anyone using openSUSE for DHCP know if setting up reserved IPs for certain MAC address is possible?

I'm extremely new to SuSE Linux. I wanted to move away from Windows and so I decided to reload my Desktop with SuSE linux.I have had no trouble until now. I'm trying to connect to my work VPN connection. From my laptop (which unfortunately is Vista) I'm able to connect without any issues. However, when I tried out the KVPN application on my SuSE linux, it just doesn't work. I get the error:
Authentification has failed.
As a side note, when I type ping google, the packets are received 100% but when I ping my company address, no packets are received. Hope this info is useful.

(I'm probably going to have my forum account revoked due to excessive usage ) I'm setting a VPN connection on openSUSE 11.2. Using the networking icon on the tray I add a PPTP connection, set it up but I receive a message 'VPN connection failed'. Googling it up I tried changing a setting called 'refuse-eap' to 'yes' but it doesn't seem to work. Here's the result from the log file:

I have been working on this for a while now and am absolutely stumped. Basically, what i am attempting to do is make my ubuntu box into a gateway for my network. I have everything working thru hard wire, but I simply cant get the wireless to work. No matter what I do, I cannot get my wireless card to transmit an essid and allow nodes to connect. I have tried assigning it in the interfaces file (shown below), and I have also tried manually modifying it using the iwconfig command. Here is the topology:
eth1: internet WAN
eth2: ethernet out to LAN
ra0: wireless out to LAN
Here is a copy of my /etc/network/interfaces file:

finding the best protocol for my server's file sharing. I will use this with 3 macs running 10.4.11 , one running 10.6.8, and one running 10.7 AND 10.6.7 AND Ubuntu 11.04. My server is going to be running Gentoo. I also need something where i can access it over the internet(and I'm using dyndns for my internet access(acessing from a outside machine)) with encryption and little hassle. I need the ability to be able to mount in finder and multiple users to be able to open a file.

I had this issue with Fedora Core 13, so I switched my laptop back to OpenSuse and continued to have the problem. I can do a host lookup for software.opensuse.com and I get a correct response ...
Code:
linux-edxs:/etc # host software.opensuse.org
software.opensuse.org has address 195.135.221.150
linux-edxs:/etc # host download.opensuse.org
download.opensuse.org has address 195.135.221.134
Firefox works. Thunderbird finds my mail servers just fine. SSH works. But then when I try to do anything involving software updates or installation, I get ...
Code:
linux-edxs:/etc # zypper update
Retrieving repository 'Updates for openSUSE 11.3 11.3-1.82' metadata []
Download (curl) error for '[URL]':
Error code: Connection failed
Error message: Couldn't resolve host 'download.opensuse.org'
I've seen others here post queries about this, and I'll tell you what it was in my case: our DSL modem's DHCP server returns its own IPV4 address as the DNS server. When I looked at /etc/resolve.conf, I saw "nameserver: 192.168.50.254" on the last line -- the IPV4 address of our DSL modem. I manually inserted "nameserver" lines for our ISP's two actual DNS servers, and everything magically started working. Why this should confuse some software under Linux, but not other software, is a mystery. It also seems to be Gnome-specific (I didn't have this problem with OpenSuse 11.3 and KDE 4).
Ask if they're using Gnome, and ask them to check resolve.conf. A lot of DSL modems and home/small office routers return their own IP address (i.e., the same as the gateway address) for the DNS server on a DHCP query. The solution is to manually edit resolve.conf and put in your ISP's DNS server addresses manually. Incidentally, just my opinion, but Network Manager needs to make this an option. Under Windows, for example, you can select "automatically assign DNS" or you can enter them manually, even if you're using DHCP. It'd be nice if Network Manager permitted that.

I'm confused as to what protocols 50 and 51 are.
Code:
-A RH-Firewall-1-INPUT -p 50 -j ACCEPT
-A RH-Firewall-1-INPUT -p 51 -j ACCEPT
The '-p' option is not for a network port but for a protocol. I've never heard of 50 and 51 protocols.

I am working as a system administrator, i got challenging work from my team leader i.e., configuring network printer in redhat 4.2/centos 5. Initially i started with redhat linux 4.2. Unfortunately i didn't get any default man pages. I downloaded the rpm package mit-lprng.3.8.27-10-rhe4.i386.rpm and ran it. I got man pages of lpd but i couldn't able to start lpd services. then i downloaded the lpd daemon startup script from this site :Now i could able start lpd services.In server system i have configured the printer locally (shared and used LPD protocol). In client system i am unable to take test page even though it is connected to desired print server.Even some times it shows "remote host cannot accept control file(data file) 32

When I installed CentOS, I forgot to modify the settings of Network Time Protocol. I need to do the following:
1. Enable Network Time Protocol.
2. Add a new ntp server to the list.
How I can do this after the installation. Is there an utility to handle this? or do I need to modify any files manually?

I'm trying to install Debian 5.03 from the netinstall on a usb flash disk. When it gets to the network initialization step, it fails and cannot get an IP from DHCP. Manual configuration does not work either. Out of desperation I installed windows to see if the network device was broken (this is a new motherboard), however it works fine without drivers even. Invoking lspci shows that it is a Realtek RTL8111/8168B PCI Express Gigabit Etherent Controller (revision ff)

Router works fine, debian refuses to work with it. I continued the install anyway but only have the first DVD so now I've got a useless base install that can't connect to the internet.
The fact that this installer has utterly failed where the others succeeded had drastically reduced my confidence in the debian team.

I am facing two issues with CUPS - 1. I have installed cups 1.3.9 over OpenSuse11 x86. Please check below -
cups:/usr/share/cups/banners # cups-config --version
1.3.9
cups:/usr/share/cups/banners # cat /proc/version
Linux version 2.6.27.7-9-pae (geeko@buildhost) (gcc version 4.3.2 [gcc-4_3-branch revision 141291] (SUSE Linux) ) #1 SMP 2008-12-04 18:10:04 +0100
I have added few printers over there and everything is working fine. I can also able to add - delete - modify any printers from "yast2 printer" command. I can also able to browse cups web interface via http://cups:631, but when I am going to manage the printers (start - stop - delete etc), none of the buttons are working in firefox5 not even in IE also. Older version of firefox is giving error as "This address uses a network port which is normally used for purposes other than Web browsing. Firefox has canceled the request for your protection." All other buttons are working properly.
2. LINUX - LINUX Printing - OK
LINUX - WINDOWS Printing - OK
WINDOWS - LINUX Printing - NOT OK
While giving printing from Windows machine (Printer attached on Linux), there is no problem to coonect the printers, but unable to print.

As i did a network restart, i get this error saying :
There is already a pid file /var/run/dhclient.eth0.pid with pid 2802 killed old client process, removed PID file.
What is this error and how can i fix it,because every time im re booting my server i lost my network config.
