The module e1000e is loaded into system. At addition VLAN the system hangs at a stop VLAN or configure other devices (sound, video). In OpenSuSe 11.3 it worked correctly.

I have configured dhcp3-server on my debian box and I'm wanting to offer dhcp on one of the vlan interfaces. The dhcp is functioning but when I test applying it to a different vlan, the original PC can still get an IP. For example: eth1 has vlan100 and vlan200. Our managed switch has the ports configured such the pc1 is on vlan100 and pc2 is on vlan2. This works fine and I can inter-route between vlans with static IPs. Our dhcp config is currently set as:
ping-check true;
ddns-update-style none;
default-lease-time 21600;
max-lease-time 86400;
INTERFACES="vlan100";
authoritative;
[code]....

I have a ClarkConnect (CentOS based) box running as my home router on a RR connection. I had the DNS servers set up to use Google's DNS server. I want to change them back to the local DNS servers but I can't find an obvious/easy way to get those address short of a) reconfiguring the router's network to DHCP them (would rather not interrupt everyone) or b) calling their tech support (kill me now!). Is there a command line tool/command I can use to query the DHCP server on the external NIC to see what DNS servers it would set me up with w/o munging my existing setup?

Using Fedora 10, can anyone tell me how to setup the network scripts to create two network interfaces for vlan x and y. Both interfaces should obtain an ip from dhcp and both interfaces should run over eth0.

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?

do you know if there is any possibility to route/force non-vlan packet to a vlan interface in Linux?

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.
dhcpd.conf -----------------------
Code:
ddns-updates on;
ddns-domainname "mydomain.lan";
ddns-update-style ad-hoc;
allow unknown-clients;
[Code].....

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

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.

Our ISP provides us with Layer 2 hardware (Modem?/Switch? (Hatteras)) for our leased line and internet access. I have been told that I should set up a VLAN capable router to separate the internet traffic from the internal traffic. I found that linux is capable of VLAN routing. Nice!
I have setup opensuse 10.3 put in two NICs and did the following
vconfig add eth0 10
vconfig add eth0 20
ifconfig public.ip.add.ress netmask 255.255.255.252 eth0.10 up
ifconfig 192.168.0.1 netmask 255.255.255.0 eth0.20 up
Plugged this NIC into the HATTERAS hardware (with a straight cable), and thought that this way I should be able to ping the public gateway or any ip out on the internet. My ISP is telling me that I should create a VLAN trunk to be able to 'use the internet', but as I understand in linux if I create any number of VLANs on one NIC they are already trunked. I also got the info, that the traffic is tagged, and I can separate the traffic reading the tags. I already read that some NICs are not able to VLAN because they are not able to handle the increased packet size.
Also that the MTU setting is important (dono' the exact value though, only that its important). I thought that a linux machine can act as a router and firewall in such a case, because proprietary switches/routers use linux as embedded os. This is my first meeting with VLAN so if this whole post does not make any sense or you think that I just need to RTFM more then tell me! I also have some (3) Dlink 3226 Layer2 switches around, but I think it would be waste to use a 24 port switch on this subject.

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:
option domain-name "XXX.XXX";
option domain-name-servers 192.168.0.1;
option routers 192.168.0.1;
[code]...
(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?

I am just trying to get SSH working between 2 local machines on OpensSuse 11.4 boxes. I have the SSHD daemon running, the firewall is configured to allow SSH to pass, and I am using SSH's password authentication. However, my machines cannot see each other. Anytime I try to SSH, I get "Could not resolve hostname<hostname>: Name or service not known."
Of course, that leads me to believe I need an entry in my /etc/hosts file. However, I use DHCP, and therefore have a dynamic IP address. Therefore, my hosts names will only be good until the next IP renewal. How in the world do I configure SSH with a DHCP assigned address?

I'm currently setting up a vlan network and after reading several man pages I still have 2 questions / problems:
1. I would want to put several subnets into one vlan.Meaning for example, I want to have the following Vlans with subnets:
vlan1 10.1.1.0/24
vlan2 10.1.2.0/24
vlan3 10.1.3.0/24
vlan3 10.1.4.0/24
vlan3 10.1.5.0/24
Is that possible?
EDIT: I found a sample configuration, sadly without any comments, where there are defined some interfaces named vlan1:0 trough vlan1:3. Could that be the option I've been looking for.However in the definition of the vlan1 device it is configured with the subnetmask 255.0.0.0 . I would like to know the mechanics of that option, too.
2. In the wlan part of the network I want to have a dhcp server distributing ip addresses. However I want hosts the server 'knows' (by mac address) to be in a different vlan than those unknown. Is there any way to achieve that? If yes, do I need special wlan access points or can I do it by my configurable switch or by the server?

In 11.3, if in "/etc/sysconfig/network/ifcfg-eth0" i set DHCLIENT_SET_DEFAULT_ROUTE="no" this seems to have no effect. If i start my box, the routing table has the "default route"-entry offered by a remote DHCP-Server. More Info: My Susebox has eth0 and eth1 and both network devices should use DHCP4. But from DHCP-offer on eth0 i want to use
* "offered IP-Adress for eth0"
* "offered NTP-Server"
* "offered Host-Name"
From DHCP-offer on the eth1 i want to use
* "offered IP-Adress for eth1"
* "offered DNS-Servers"
* "offered Default Route"
