OpenSUSE Network :: How In World Do I Configure SSH With DHCP Assigned Address

Aug 7, 2011

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?

Networking :: Configure A (openSUSE) Client To Dhcp To EBox DHCP Server - Lease An IP Address

Mar 25, 2010

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?

General :: Ifconfig Alias Address Assigned By DHCP

OpenSUSE Network :: Firewall Settings - Configure - Interface Isn't Assigned To Any Zone?

Apr 20, 2010

I have a work desktop plugged into the work network. As I opened my firewall settings I noticed that it is turned off. My question is how should I configure it? I saw that the interface isn't assigned to any zone... I should assign to internal zone and open some port that I need in order to work? There are some guidelines for configuring the firewall?

OpenSUSE Network :: Can't Get IP Address From DHCP

Jun 3, 2010

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.

Security :: Restrict Access To Network To Only Dhcp Assigned Ip's?

I'm trying to tighten up my network a bit. I've given my dhcp server a list of static mac addresses and ip's for computers i know, and a very short range of dhcp addresses that are redirected to kittenwar.My dilemma is that if someone has my wireless network password, or an ethernet cable, they could set the ip address manually and gain access.how can i deny them this pleasure?im running dhcpd3, and iptables on a debian/lenny intel 2.4 box. dd-wrt is running in a linksys wrt54g and is handling the wireless security

OpenSUSE Network :: Having IP Address Via DHCP But No Connection?

Apr 9, 2010

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

OpenSUSE Network :: Dhcp Client Does Not Receive The Dns Server Address

May 18, 2010

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.

Ubuntu Networking :: Static IP Address And The Install Configures For A DHCP Configured Address - Network Not Starting

Dec 16, 2010

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:

Fedora Networking :: No IP Address From DHCP Server On Wireless Network?

Feb 12, 2009

I have installed Fedora 10 on my A860 Dell Vostrol Laptop with AR242X Atheros Wireless card. Wireless card worked out of the box and i could detect wireless network and connect to it. But i have a problem that, my wireless connection is not able to get IP address from the DHCP server. Please help me out what can i do to get this working. I am using WEP security and authentication is open system.

I have windows 7 beta installed on the same machine and on that wireless network works fine so i am sure that there is no problem with the wirless network. I am using DIR-300 router from D-LINK. I tried to see packet log on wireshark and there i see that there is no reply to the DHCP discover message. Actually i don't see any RX packets at all. Which is not normal as there is traffic on the network.

General :: Determine Whether Computer 'gets IP Address Information From Dhcp Server On Network'

First, (for samba) how do I determine whether my computer "gets IP address information from a dhcp server on the network," and whether "the dhcp server provides info about WINS servers ("NetBIOS name servers") present on the network," and consequently whether a change to my smb.conf file, "so that DHCP-provided WINS settings will automatically be read from /etc/samba/dhcp.conf," and whether the dhcp3-client package must be installed?

OpenSUSE Network :: Access To NX Server From Anywhere In World

Jan 5, 2010

I have run into a problem using FreeNX in combination with public key authentication. I have Googled myself silly, but I can't find the exact answer to my problem. I am hoping that someone here will know the answer. First, let me tell you what I am trying to accomplish:

- I don't want my ssh server exposed to the Internet with password logins enabled. I only want public key authentication.
- I want to have access to NX server from anywhere in the world.
- I want NX to use a custom keypair, not the default supplied by FreeNX.

My environment:
openSUSE 11.2 (client and server)
KDE 4.3.4 (client and server)
FreeNX-0.7.2-26.5.i586 (server)
openssh-5.2p1-9.1.i586 (client and server)
NX Client for Linux 3.4.0-5 from NoMachine (client)
qtNX Client qtnx-0.0.1SVNr281-215.1.i586 (client)

The login problem persists, whether I am connected to the same network or to another network. Since ssh logins work, I don't think a firewall is the culprit. What do I have working so far: - The ssh server on the remote host only accepts public key authentication and I can login from the client without problems. So far so good. - FreeNX is installed on the remote host, using a custom keypair.
Authentication with this key works. I can login from the client with the nx user and the public key.

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?

CentOS 5 Hardware :: Realtec Ethernet Card Assigned Wrong MAC Address - Fails?

Dec 17, 2009

I have an HP Pavilion A6750F with an AMD Phenom 9650 Quad Core. 8 GB memoryThe NIC is a REALTEC Semiconductor RLT8111/81688 PCI Express Gigabit Ethernet Controller.The actual MAC address for the NIC is 00:24:21:55:DE:40I have loaded CentOS 5.3 on this host three of four times in various configurations and patching levels.THE PROBLEM: The system identifies the NIC as having MAC FE:FF:FF:FF:FF:FF.When this happens, the network connectivity obviously stops working.It identifies everything else OK, just maps the wrong MAC.I'm no sure how to troubleshoot this problem. I tried rebooting a couple times and once that fixed it. Usually it does not. I reloaded (gasp) Windows Vista on it and it worked ok.This last time, I reloaded CentOS it hung on the bootup (ASK ??), I reset it, it rebooted and everything looks ok; for now.
The system says it is presently using driver r8169

Ubuntu Networking :: Assigned Computer A's Static Ip To Computer C Without Changing Dhcp Setting?

Aug 18, 2010

I set up a dhcp server in the lan and assigned static ips to two computers, computer A and B, according to their mac address. Everything was running fine. But when I turned off computer A, connected computer C to the network, and assigned computer A's static ip to computer C without changing dhcp setting. Computer C was able to access the internet. When I turned on computer A, dhcp couldn't assign an ip address to it, and computer C showed an error message of ip conflict and failed to use internet. I wonder if dhcp server is able to prevent other computer from using the same static ip that is already assigned to a computer according to its mac address.
