OpenSUSE Network :: Using As A Network Gateway - Renew DHCP Lease
Jul 15, 2010
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?
Looking at var/log/messages below, it looks like I'm not being offered a lease on this particular network. I can successfully connect to the network because iwconfig wlan0 reveals my network ssid and the access point I'm connected to. But pinging google.com gives me nothing..
Code:
root@darkstar:/# tail -f var/log/messages | grep dhcpcd Mar 28 15:45:42 darkstar dhcpcd[5329]: wlan0: adding IP address 169.254.76.182/16 Mar 28 15:46:13 darkstar dhcpcd[5329]: wlan0: adding IP address 169.254.76.182/16 Mar 28 15:46:44 darkstar dhcpcd[5329]: wlan0: adding IP address 169.254.76.182/16
first: PXE flawless bind to dhcp address but put next binding state to free second: when installer calls init script to reinit ethernet driver (e1000 (vmware)) binding fails 11.2 opensuse fail to reinit dhcp with log entry "no free leases" third: when manual set network install works how to preserve dhcp lease on reinit of driver?
I 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: DHCPOFFER from 10.45.48.108 openSUSE11232CL1 dhclient: DHCPREQUEST on eth0 to 10.45.48.108 port 67 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?
Does anyone know if you switch networks Where you have your servers hosted on a Non-DHCP Network, and you switch your IP addresses, then do you have to switch change/assign your new gateway address? I'm not sure if its manually assigned? How do you do it? Also what about nameserver resolving?
I have openSUSE 11.2 installed and i need to create a gateway server that allows virtual private network connections. I want to play with my friends some lan games, but we are in different networks, so i want to create this gateway server so we can connect with VPN clients to this server and play freely.
I installed openSUSE on one of my work system. The network port wasn't working when I was installing, but works fine now (checked in Windows). But for some reason, I am not able to configure the network. I used both Dynamic and Static IPs (both work fine in Windows) but still no go. I am using Yast Control Center for this purpose. I can't even ping the default gateway when I am using custom settings. When I use dynamic settings, it says Unreachable Network.
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.
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 recently upgraded a 11.0 installation running on Xen Server to 11.3. I am experiencing frequent network disconnections now. The ip address and default gateway is assigned statically. However, the system seems to ignore the default gateway after a while. Then after several minutes it seems like it comes back.

When my sessions suddenly die and I have to coax it into routing correctly again.
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.
I'm currently working with wireless network kernel module.
This device initialiy gets its IP address by using DHCP, but the problem is sometimes the new IP assigned for internal reason.
So what I want to do is assigning new(changed)IP address into exsiting interface, or occuring DHCP renew event to cause update IP from kernel level. This shold be done without user's intervention, so whenever the kernel module detects IP changed(via underlying wireless communication), it automatically correct update its IP address.
Q1) any functions or api to cause DHCP renew event from kernel level? Q2) or any functions or api to assign IP address to specific interface?
I had 200 workstation with both Windows XP and SuSe Enterprise Linux. Sometime, a few clients can't get IP address from DHCP with SuSe OS. With the same computer, if I reboot and chose Windows XP, it work fine. The log message or the boot message was "No IP Address yet ...backgrounding". I tried to reconfig network device, restart services, change another port, change another line LAN, set static IP Address .... but there's no luck for me.
I have a small network setup and I cannot get DNS to work. DHCP is functioning normal and working fine but it cannot update the DNS pointers for some reason. My files are below.
I have a laptop running OpenSuSE 11.2. I use the Yast menu to set up network settings via "traditional" ifconfig setup (not NetworkManager), because I found NM unusable in prior releases when doing network gymnastics such as router re-flashing, LAN reconfiguration, etc. where I needed control of the IP address, netmask, DHCP, tftp, etc. My laptop works fine with Yast "traditional" ifconfig configuration for eth0 connected to router to Internet. Works fine with Yast ifconfig configuration for USB WiFi as wlan1 to WiFi router to Internet. Also works fine for virtual machines on vmnets NAT-ed to the Internet. Works fine as long as there is only one network connection, that is.
Now, I have a second laptop. I want to network laptop #2 eth0 to laptop #1 eth0 for file transfer and/or Internet access WHILE laptop #1 is is linked to the Internet through wlan1. Unfortunately, I have not figured out how to get Yast/Network Configuration to do that. I have not been able to get Yast/Network Configuration to see both wlan1 and eth0 at the same time--when the Yast utility finishes, I do >ifconfig and >route, and I find that I have lost either eth0 or wlan1. Thus, when I do direct-connect file transfers, I loose the WiFi Internet connection on both machines.
I suspect that it might have something to do with Yast/Network Configuration utility not being able to handle two network interfaces on the host with different IP addresses. how to properly put an OpenSuSE machine on two networks simultaneously? And then how to turn on IP forwarding so that I can use laptop #1's WiFi as an Internet gateway for laptop #2?
i don't know the proper commands to list my system information. Up until recently, the internet worked fine, but suddenly stopped. I opened up YaST2 and found that the network device was set up to never turn on, and i switched it to "at boot time" but it still doesn't work.
I've just installed opensuse 11.2 with the network installation iso. During the installation, it has got the IP via DHCP without any problem, and I has downloaded all the needed packets without problems... But when the installation finish.I have no network connection It's strange, because I have IP address, I get the IP from the DHCP server, and I can see the IP addreess if I do "ifconfig", the default route and even the DNS servers in the resolv.conf file; but I cannot ping my gateway (that is the DHCP server as well!!), I cannot ping anything in my network and either anything in internet. I see a network error at the start, but it finally gets the ip address. In the dmesg, the last message repeats over and over. The machine is a Hyper-V virtual machine, but as I said... I worked very well during the installation, I don't know what is going on. I've tried to reinstall, but it doesn't make any difference
basing on the research and trial and error which am still on the trial stage with errors here's the scenario We have 5 VLAN's with and existing Windows DHCP Server, that serves 5 Scopes for the 5 VLAN's 192.168.100.x and 192.168.200.x IP Addressess evrything works well on our Windows DHCP server, what i want to do is replace our windows dhcp server with a linux box , with one NIC , ive read about VLAN on linux 802.xx something and VLAN Tagging am already confused on what to do.. what i want to ask you guys is an assistance implementation the vLAN on linux then the dhcpd.conf
I cannot uncheck the "Change Hostname via DHCP" box because it is disabled. Next to it says "No interface with dhcp". How can I fix it? I'm using OpenSUSE 11.3/KDE4
I have setup an dhcp server wich allows ICS, and a samba server as a PDC. I can access the shares from windows if I type the server Ip (ej. \192.168.0.1), however if if write the address (ej. \dbaserver) I cannot access them.If I type ping dbaserver on a command prompt, it returns 127.0.0.2 not 192.168.0.1, what could be wrong. I asume because of this I cannot join the domain also.
I am trying to enable DHCP so that it will give out IP's to some XP boxes when they boot. I have had success doing it dynamically, but not statically using the host declaration. host xpTest { hardware ethernet 00:50:56:2A:3B:00; fixed-address 192.168.100.2; } My question is, what should the subnet declaration be if I only want to hand out static IP's like this? Also, the host is the same name that is specified in /etc/hosts correct?
I'm maintaining a very modest network at home, with OpenSUSE as OS on the server. I got the DHCP and routing working by following the instructions in the wiki. However, every time I run dhclient on the server/router, it appears my own DHCP server assigns an address to the internal network card despite the fact I specifically assigned it to be static using Yast. The situation resolves itself when I restart the network services with the command /etc/init.d/network restart. Otherwise no problem, but it also seems the internal network card gets a "new" IP from my server every time the external card requests one from the ISP. This is more of an issue.
Automatic Proxy Configuration via DHCP | AGIX Linux Tutorials & HowTo's | Ubuntu Focuson openSUSE not work, Why? # These 2 following lines are the key to your pac success:option local-pac-server code 252 = text;option local-pac-server "http://192.168.1.254/wpad.pac";
I configure my server just like on the link found in novell i hope some can help me here. my client is able to recieve DHCP address and everything is working fine on the network how ever my client cannot pullup any website, but my server is able to pullup whats wrong on this one.
Cool Solutions: HOW-TO: Set Up a SUSE 10 Machine As a Router
I'll try not to be too wordy. Want to get my openSUSE 11.2 (fresh install) laptop to see my network shares ...not to be a server or share any files. I've looked at 50 websites and everything seems to be "server" and "share" oriented. Maybe I (newb) am confused by the terminology...
I have a router that provides DHCP. My LAN PC's consist of a Vista laptop, an XP DAW, and a Kubuntu file server. Somehow I got Kubuntu configured properly, all of the Windows machines can access it and vice-versa. The Kubuntu smb.conf does not work on this laptop, and it seems overkill -no shares needed here. And yes, I get DHCP and interweb on the laptop -posted this with it.
All I want is access to my (other) network drives from this (openSUSE 11.2) laptop. Not a server, not to share. This is easy... right? It's driving me nuts Is there a Samba configuration that will let me jump onto networks and surf Windows/Samba shares like any old Windoze box browsing Network Neighborhood? Do I have to be a Samba guru?
I have installed a working DNS server on my home network. I have an unique server, devoted to dns, gateway, storage which runs opensuse 11.0 (I known that it is rather old). Two new clients require DHCP. I have installed, using yast, a very simple DHCP server, according to the following config:
(I have tried to add "ddns-update-style none", and to remove the ntp-servers option, since my server is not a time server, without success). Unfortunately, even if the client (a mac running OSX 10.4) receives a right IP and gateway address, it displays neither dns server address nor default domain name. The same mac, on my office network (not managed by me), receives everything.
I have installed openSUSE KDE 11.3 on my notebook. Everything looks great, but I can't connect on internet. It looks like dhcp don't work. Wireless works fine, only auto eth0 don't work.
I set up a server that has dhcp going. This works 100% as I get ipaddresses. My question is how do these internal computers connect to the internet? There is a proxy that needs to be passed as well...
Is this just a simple case of portforwarding or is this a completely different thing?
