OpenSUSE Network :: NAT Going Out On Other Than Default IP?
Jan 12, 2010
How to achieve such functionality:I have some server based on openSuSE 11.0 which have services as HTTP and FTP but also working as firewall-gateway.The default IP for this server is: 10.0.0.5 and with such IP working HTTP, FTP and Masqueraded computers in local area network.I did another alias in interface with IP: 10.0.0.10 and I want to change address for Masquerading computer to this IP. How I can do this with SuSEfirewall?

I've not found how to configure more than one ip address with network manager.Nor with kde nor with plasmoid network manager.I need several virtual ip addresses for eth0 when the "default" of eth0 is connected i.e. "Connected to Auto eth0" should initialize the virtual interfaces.I have not found no even how to configure the ip address.I think this will be used from ifup config in yast or not?There I have the virtual interfaces but they are not taken from network manager.And last but no least: Is it possible that when using network manager the eth0 is enabled even no user has logged in?

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.

First off How do you disable IPV6 access on all connections used on the pc-is there a way to test for ipv6 connectivity?
Secondly how secure is a default opensuse 11.04 machine out of the box? should i be making some changes to the default configuration?
Thirdly what does the default firewall settings do? on my network i use my wpa2 psk aes connection via my local wireless network-in the event that some can hack into my wireless would the opensuse firewall prevent direct access to my pc from a attacker on the same wireless subnet?
Fourthly when does opensuse 11.04 go out of date? in a year from now?

I am setting up a LAMP server for the first time and ran into an install problem for my application. Several directories for my app need write permission for the web server. The instructions say:"In linux, recommend changing owners of these directories to the web server. For example, in many linux OS's the web server user is apache', 'nobody' or 'www-data.' So, if apache were the web server user name, could use the command 'chown -R apache:apache directory_name' command.
I've tried all three, but with no luck. I haven't yet changed any server default settings. So, my question: what is the default server name in opensuse 11.2?

I've been seeing a bunch of issues with the /etc/resolv.conf not picking up the nameservers for 3g connections, and managed to fix that issue using tips found here.. the one thing I m having a problwm with is my 3G USB modem not picking up a default route/gateway. I can connect using KNetworkManager, get an IP and nameservers, but.
[Code]..
And to top it all off, I cannot figure out what the default gateway should be from verizon to just write a script out myself that'll do it automatically.

Okay something i find very odd. When booting the livecd network manager is there, i select my wireless net and connect. Yet i install and it doesn't appear, i click the network bit under the status tab of the computer menu and by default it's using ifup and not network manager...anyone else get that? Or is it supposed to be that way...seems rather unfriendly though.

I have a static ip on my wired (eth0) connection. I thought I had it well set up in yast. In the routing section I do have my default gw coming up there, with the the right nw i/f (eth0) associate with it. However, when I boot up, y config seems to ignore that fact, and I have to keep goign to root and typing "route add default gw <mygwip>" each time, which is something I want to avoid. Isn't it odd that the route settings created by yast have no effect? If they did, the route would be set up on bootup and I would haven't to do that typing.

I'm currently struggling with the following problem: Connecting to a wired network with NetworkManager (0.7.1) is no problem at all: Everything is set up automatically, including the default route:
[Code]....
When I now add the route manually it works. But as soon as the cable is plugged in, the NetworkManager overwrites the routing table entry again (which makes it quite annoying). Does anyone know a way to avoid this behaviour?

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.
Code:

I have setup up an Opensuse as a simple we/application server.It handles requests for various things and will need to send out email on occasion for things like password reset requests, information / warnings etc. etc.This is a standard OPenSuse 11.x install with defaults so it comes with Postfix as the mta.I do not want a mail server I just want to send out via my clients mail server which is hosted exchange rackspace, which simply requires SMTP auth to do so.What would be the proper way to do this so ALL e-mail send from this machine, regardless of account like WWWRun or when logged in and sending from the command line has the same sender all the time.

Recently I purchased a new laptop and installed openSUSE 11.3 x64 Gnome. I was running openSUSE 11.2 x86 Gnome on my previous laptop. Most things are working well, although still tweaking things here and there.
The biggest issue at the moment is starting the network. When I boot the system it loads into desktop (gnome) no problem, but then takes between 3 - 5 minutes to come up asking for Default Keyring Password before it will launch network manager. Everything else has loaded and it running fine except the network.
The first time I launched the system (after install) it worked perfectly, however soon as a set the password for the Default Key this started happening. The time delay before it launches does vary each time but always around 3 minute mark.

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"

I have a fileserver running openSUSE 11.2 and samba services for file access from MS Windows based workstations. My question relates to changing default permissions on files and directories created from the windows clients.
Following are extracts of the /etc/samba/smb.conf file :
Even with the above entries, sometimes there are files and directories created by the windows clients having permission
Probably my lack of understanding in ACLS.

Im trying to setup multiple domU through the default bridge setup. I am able to access only one of them through the network at a time. If you ping one of the domU it works perfectly but you cannot ping any of the others until you stop pinging the one and even then it takes a bit before you can. Ive looked around for a while and seen similar problems but nothing ever seems quite the same. Im probably missing something really stupid. Or is this the way the bridge is supposed to behave? Do i need to use a routed virtual network?

I know this sounds like a poorly asked question, but I was asked if our Linux systems are running in "FIPS mode". This document [url] says
Approved Mode
The FIPS 1402 Approved Mode of Operation is the operation of the FIPS object module when all requirements of the Security Policy have been met and the software has successfully performed the powerup and self test operation (invocation of the FIPS_mode_set() function call). In this document this Approved Mode is referred to simply as FIPS mode.
Is this the default for OS 11.4? The only place I know that OpenSSL is being used on our systems is with OpenSSH.

Hearing the praises about fastness of xfce all over the net i decided to try it for my fav ubuntu i rightaway installed xubuntu (without creating a bakup of the names of programs that were going to be installed which i generally do to fully remove any utility that i install for test) i understood that fast for xfce actually meant light(stupid me). now i switch back to gnome onlt to find xfce stuff like pacmn file browser and wicd to name a few. i removed the pacmn browser but when i remove wicd the default network manager does not show up in the task panel i would like to know:
1.how to get back to gnome'z default network manager AND
2.the list of utilities installed when xubuntu-desktop is installed

if you try to browse the web from the machine, or log in through a nomachine (nxclient/nxserver) session, it claims there is no internet conenction. You have to run System|Administration|Network and select the stored "Location" for our wired connection. There does not seem to be an option to make this (one and only) "Location" the default. If the machine is up and incoming connections are possible (samba & apache), surely outgoing connections should be working without extra fiddling?
The issue with nxserver (nomachine) becoming unavailable on a re-booted unattended machine (unless someone logs in AT THE MACHINE and runs System|Administration|Network) is causing problems for remote access.

I seem to have somehow mangled my my Ethernet and wireless's connection to the outside world on my Ubuntu 10.04.1 machine. I was trying to get a static local IP, and that worked great for a few days, until I lost all Internet access completely. However, I can connect to my router on my wired connection - but not the wireless.
You can see what I did here: http://ubuntuforums.org/showthread.php?t=1600784
Now, I just want everything to work as it did when I installed Ubuntu 2 months ago. How can I reset Network manager back so that it just works? I realise that don't need a static IP, it can only be 2 IPs, as I have 2 PCs only.
Or is there some better way to manage my networks? I'm not the best when it comes to those.

I'm using F12 on an old box which I have fitted with a new networkcard. I'm using the box as a music server (Twonkey) and want to use the new card (gigabit - eth1) as the default, but seem unable to. I can't switch of the mainboard ethernet option (eth0) in the bios and have tried to change the settings in the ifconfig-eth0 and -eth1 files by changing the hardware addresses as elsewhere recommended, but that doesn't work. During start-up it then gives me an error message that the MAC number was not the expected one. This would indicate that the network options are kept/read elsewhere. I'm not very familiar with Linux/F12. how to make the card the default option instead of the mainboard option.

On Linux Mint (Gnome) i used to go to Network drive. that is on the right hand side of Nautilus there is a short cut for Network. in there i could see my network hard drive and other laptops connected to the network, and i could access my files. but on OpenSuse, when i open the network folder, nothing comes up. may be it needs some sort of configuration.

So I have two network Interfaces
eth0 - NAT behind a router
eth1 - Public IP
When ever I restart the machine, both interfaces pull a IP, but the it randomly chooses eth0 or eth1 to have the gateway. I want the gateway to be eth0 always.
[Code]...
Is there some file or setting I can modify in Fedora10 that will always choose 192.168.1.1 on eth0 as the default gateway?

The other day I was using BitTornado and it was running so slow it was almost unholy. After some research I found out that if the yellow light was on it means I couldn't receive any incoming connections and had to open some ports on the firewall. That, my friends, is not the problem. I tried to manually open up the bittorrent port and did some other things that I can't quite remember but eventually I accidentally killed all bittorrent functionality on my laptop.
Is there any way I can reset my network and ports back to the default settings or am I utterly screwed? I'd really prefer not to have to reinstall my whole OS just to fix my bittorrent or worse, have to download on Vista *shudders*. I'd rather go back to my uber-slow bittorrent than none at all. I've tried everything I can think of, even the godlike might of Google couldn't get me out of this one. Now I am forced to bother you, all because I wanted to see a damn sci-fi film from Switzerland (Cargo[2009]).

Have searched for this and am sure the answer is out there somewhere, but I can't find it. My wired network is configured as AUTO, and is DHCP, I can add a new static config, but can't get it to load, as the original AUTO always loads on a reboot. I need to be able to run sudo Network manager so I can reconfigure the default..

The default name server set by network manager works just fine much of the time but there are times when it slows down badly. What I want to do is to have network manager add extra nameservers to the list when it starts the network.

So I've been asked to install a file/printer server and, possibly, inet proxy for a small office (5 PCs). My concern is: There are:4 PCs on XP x32 1 PC on Win7 x642 Printers, one of them with a scanner Some buisness software they use does not cope with win7.Had hard time installing additional x64 drivers for printer (which are obsolete by now, I guess). Network runs on a simple router which is connected to internet. For now they have been using simple sharing of C: folders, which had freaked my out a bit.
So..Despite XP being old and a presence of x64 machine on the network, do I:install x64 server edition install x32 one What additional software, besides Samba and printer/scanner drivers, I will need to handle both architectures? I have rather basic understanding of how servers work, i.e. I run samba, apt-cacher, torrents on my home network.
