OpenSUSE Network :: How To Setup With Firewalls On Two Machines
Jan 6, 2010
I have several Windoz machines in a peer-to-peer network and now two SUSE machines, one 11.1 and another 11.2.I have a network printer accessible now to all the machines.My next step is to be able to share files between all the machines and several network drives. I know how to set this up between the Windoz machines, but the only way I can get the SUSE machines to see the network (and be seen) is to shut down their firewalls, and I don't think that's how you are supposed to do it?Can someone point me to what it is that I need to read, or is there a FAQ somewhere to help get me started?
I think that this has something to do with Samba and I installed Samba (client or server? I forget) on the 11.1 and 11.2 seems to have it already built-in, but I don't know how to set it up with the firewalls on the two Linux machines so that it is all seamless (as if anything can be seamless).
I have a laptop and a Desktop both systems only used by myself behind a router. Ubuntu Lucid on both and 64 bit systems. I have installed NFS with the desktop as server and Laptop as client. The NFS only works with the firewalls (UFW) disabled on both machines. My current setup on the desktop ufw is
I am new to networking and trying to setup my own local area network using virtual box machines. I have installed BIND 9.7.3 using yum in Fedora (dns server) and created all necessary .conf and zone fil es. I am successfully able to resolve domain names on this host machine (dns server). for example dig @dns.domain.lan client1.domain.lan correctly resolves domain name.
I just installed open Suse 11.3, and I cannot SSH my school. Upon further investigation I could not even ping any machines outside my local area network. Ironically I could nmap machines outside my local area network.
Does anyone know how to permanently enable X connections from all machines on my local network. I keep having to enter 'xhost +' to allow X connections.
I've been learning linux for a while now with half an eye on making a career out of it in future. One sizeable gap in my knowledge at the moment is networking. Is it feasible/desirable to set up a network of virtual machines to use as an environment to learn networking? My budget is non-existent so I was hoping to be able to get a basic understanding of the principles from installing a few desktops, a virtual gateway etc on VMware workstation on my laptop, and doing a lot of reading online.
Is this feasible, or will I just end up learning about virtual networks instead of real ones? Also how much power would be required, because my 3GB RAM lappy has just gone bang and all I have now is a (new) 1GB RAM lappy.
I'm having problems with hackers from across the globe trying to get into our servers. Why? i have no clue. nothing of value in my servers worth getting.
Right now my service only does business with USA. So I'm trying to find a way to block all Non USA traffic. I called my hosting provider and they are unable to help. Said it was up to me to do this.
Well I've already taken care of the TCP Wrappers. by spawning a small C program i made that uses MaxMind's GeoIP system. to automatically deny access. Now i need to do something about all the other network connections that come in to services that do not use the TCP wrappers.
So i was wondering if IPTABLES have a way to spawn a sub proccess like TCP wrappers or if there was any other firewall software out there for linux that would let me achieve my goal.
I only have one IP adress to access the server. But the server will host 3 web sites and I want them to be hosted in a vm. So, I want to setup 3 virtual machines to do it and use apache reverse proxy and vhosts to redirect the domain requested to the right vm. Now. I understand the concept, but I am not an expert to set that up....
I have an openSUSE 11.3 server. So, I have to set a virtual machine server, is that right? I have been told that I cannot do it with VMware server in oS 11.3. Can I use virtualbox for this? I only have to install virtual box? Is there a special version to install? Once the virtual machine server is install, is it trivial to create 3 vm? So, I want to know wich are the steps I have to take to set that up.
I used to have my print server with cups in openSUSE 11.1 and it used to work perfect. I was able to print from both linux machines and windows. But since I Installed openSUSE 11.2, I'm only able to print from linux machines. In windows XP I'am able to find the printer and install the drivers, and everything seems to work, but when I send the print command, it creates an error. I have three XP pcs that were running perfectly, and now neither one of them print, so I know is a problem with the server itself. I have all the samba and cups services activated, and the firewall is set correctly, but can't figure out why it is working with linux machines and not with windows.
I have OpenSuse 11.3 with VirtualBox on it, and with installed Oracle DB (on host OS).. but, sometimes this computer is disconnected, without it's gateway (adsl router)... and in that case, I cannot ping from virtual OS to host OS, or another virtual OS. I tried to use 'Host only' option within VirtualBox, but it doesn't work. What should I do? It seems that virtual machines requires some kind of gateway/router, but since machine is disconnected, it's not working.. how could I fix it?
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 am trying for the last many days to setup my opensuse 10.3 as Samba PDC Server according to the URL mentioned below, but in vain:How to setup SUSE 10.3 as Samba PDC - openSUSE When ever I try to join a Windows XP machine to the domain setup on Opensuse, I get the error:'The following error occured while attempting to join the domain. The network path was not found'. What could be the reason for this error despite of the fact the I am able to ping the FQDN of the PDC from the XP machine, but the XP machine simply denies to join the domain because of the above mentioned error.
I have an opensuse 11.3 install which I want to set up as a network boot server to install Solaris 10 on a Sun Ultra 10 client. According to what I've read, this requires rarpd and tftpd which I've set up on opensuse, but also bootparamd which I can't find for 11.3. It seems it was last included with opensuse 9.2. Does anyone know if it's available, if I could use the suse 9.2 version, or any alternative?
while trying to set up Xen Virtual Nodes we encountered one issue with the network (which is why it is posted here On the DomU the interface is provided by a bonding -bond0- of three NICS. Now the Xen network script a) does not take this bonding b) destroyes even this bonding From a number of posts I assume I have to configure this by hand, correct? Is there an instruction how to do this? Simply create a bridge on top of bond0??
I'd like to have a set up where my Ethernet card has a static IP set up but my WiFi card doesn't.Currently I have a profile for this set up in Network Manager, however on boot up and every time I replug the cable Network Manager chooses the default "auto eth1" profile. I manually have tochoose my own profile for the Ethernet card every time. How can I make it default??I know the workaround would be to use ifup but then I lose the ability to quickly change access points for my WiFi card so that's not a solution for me
I've just installed openSUSE 11.2, one problem is suse didn't find an internet connection when suse performed the ..."automatic system configuration. This routine attempts to configure your network and Internet access and sets up your hardware"... Where can I manually configure the network. I'm in the network folder now no luck. I've been using every documentation I could find Novell Documentation and DVD installation/11.2 - openSUSE Network Status: Unknown network status
I successfully added/shared a network printer in SUSE 11.3 32 bit, but when I try on the 64 Bit box it didn't work out very well.What ports need to be open ? Is it necessary to open port 631 in YAST->Firewall->Advance- >UDP and IPP ?(TCP 631 already open) What services need to be running? Here is the error log :
[16/Dec/2010:19:25:43 -0500] [cups-polld xxx.xxx.xxx.xxx:631] CUPS-Get-Printers failed: Forbidden XXX is my server IP
I am unable to do my network setup. I have a lan connection. I used to easily setup it in windows xp in network connections > internet protocol > properties. But I do not understand anything in linux. I have installed latest version of open suse 11.1 and KDE environment. Secondly I am unable to play mp3 files on it and I do not hear any sound at startup too. I *945* motherboard with a inbuilt realtek lancard and it is working fine on windows.
I'm trying to ssh to a client machine which as freeipa client setup Login works great but ssh via GSS.Is there a way to see what's being sent where? I already have the highest debug turned on the ssh side.
I've been trying to understand how Linux creates the network/interfaces on a machine (been reading the Linux admin guide), but as I'm pretty new to this subject, I've got lost in the forest.
To provide with my goal: 1.) Learn about network setups on Linux 2.) Be able to maintain my own (virtual) network 3.) Configure my (virtual) network
I want to setup some virtual machines that will use the same architecture and debian-version as my host-machine. I have started to setup VMs with a netinstall-image and now want to add more software using apt-get. As most of the software I will use is already installed on my host-machine I wonder if there is any way to configure apt in such a way that it will not download packages from the internet, but will use the packages from my host-machine to save network-traffic. Is there a good may to populate VMs using the debs from the host-machine.
I'm trying out Fedora 12 and am so far impressed by the speed (long time Ubuntu user but by no means an expert). I can't get synergy setup between the fedora box and two windows machines to the left and right. Am I missing something (with the difference between Ubuntu & Fedore perhaps)?
I have 4 debian boxes networked together through a basic 5 port switch. I am trying to simulate 2 Local Area Networks joined together by a WAN. Right now I can communicate with A <--> B, B<----> C, C<----->D. However, I cannot communicate with Host A to Host D which is the whole point of this experiment. It has to be my static routing is not right. This is a confusing area to me. Right now my routes are
I am trying to build a file server with RAID 5 over a couple of 1TB HDDs, to serve about 10 client machines using Ubuntu Server. I already own a 22-port switch: HP ProCurve v1810G-24 Switch (J9450A), which I am assuming will do the job. And for the actual server I am thinking of buying: HP ProLiant DL120 1U. Will this hardware suffice, or am I missing something important to get the whole thing running?
we are having new printers. At the moment we over 1000 machines on multiple sites but no print server they are manually added on the machine ( I know don't ask).
Anyway there is no way they would let use a windows server so the only option I have is to use linux however I little unsure if it is capable of doing the job I need it to do. Basically I want to add the printers on the linux server either using samba or ipp (I would assume samba would be best).
The reason i want to do this is when we have to do around the machines I just want to go around the machines and just the map the printer and it brings down the driver and config etc as we want them to duplex. The issue is I been trying to gain information on the internet and getting conflicting information apparently I can add the windows driver onto the server so when I map the printer it brings it down. However some guides state you still have through the whole process of adding the printer and then choosing the driver etc. Which kinda of makes it pointless to do the printer server since I would already have to do this anyway if we don't have one.
I just want to go be able to go around the machines and for example click star run and do something like \192.168.1.1printer01 and then it done kind of thing.
i've just setup a vps server with 11.4 everything is almost look fine now, but i couldn't setup a nameserver, i've searched on the internet about that but directories is different in suse. anyway i registered a domain on onlinenic yesterday and i want to use this domain as a nameserver and my hostname. how can i do that ? and do i need to have at least 2 ip for that ?
I just installed Opensuse 11.2 today and I'm eager to start downloading and customizing, but I can't set up a network. I originally installed it with the GNOME desktop, and when I opened firefox i could only connect to [URL]... and [URL], other websites timed out, even if i got to them via search results or URL.
Now, I reinstalled using the KDE desktop because after a little thought I preferred it, but now I can't even connect to these search engines at all. I don't know how to configure the network! It's through the onboard ethernet port, ethernet cable direct to modem.
I have tried all kinds of DNS services. Like opendns, Google DNS, 4.2.2.x, Scrubit, DNS Advantage.In my experience none of them are consistent enough & there is a fluctuation in their performance.A guy told me to try enabling DNS cashing on my openSUSE box.I don't know much about DNS caching.So, I want to know
(a) Will enabling DNS caching improve my Internet experience ?
(b) Is DNS caching enabled by default in openSUSE 11.4 / How to find out ?
(c) If not enabled by default, how do I enable it ?
