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.

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.

So in an effort to increase the speed of my netbook, I removed Ubuntu and installed Lubuntu on it. When I tried to mount my samba share as I normally do, I noticed it wasn't able to connect - mount error(113): No route to host. Sensing something fishy, I attempted to ping the machine (both by name and by IP) - Destination Host Unreachable.The machine I'm trying to connect to is using Ubuntu 10.04 x64. I attempted to ping the other way and it was able to connect to the netbook just fine. When the netbook was using Ubuntu, it was connecting fine. My iptables check out ok, but here is the output of iptables -nvL:
Code:
Chain INPUT (policy ACCEPT 213 packets, 21635 bytes)
pkts bytes target prot opt in out source destination
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)

Does lubuntu have some funky firewall built in to it that I can't find? (I've Googled for information on a Lubuntu default firewall and can't find any)
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.
View 2 Replies View RelatedI'm working with a Ubuntu 10.04 LTS system with two network interfaces (both Ethernet). I wish to setup this system such that it is simultaneously connected to my local and an OpenVPN network and able direct traffic between the connections depending on what program is sending the traffic. The problem: Under my current OpenVPN configuration all network traffic is directed to the VPN.
My OpenVPN config file (some details omitted)
--remote [gateway ip] # vpn12 load:
--remote [gateway ip] # vpn11 load:
--remote [gateway ip] # vpn15 load:
--remote [gateway ip] # vpn16 load:
[code]....
In practice, I would like OpenVPN to operate out of one of my two network interfaces and leave the other interface connected to the local network. Then by default all network traffic should be directed to my local network unless I specify (on a per program bases) that certain traffic should go though the VPN. These two network connections can (should) stay completely independent of each other and do not need to talk to each other.

View 9 Replies View RelatedOne question that weight a lot of points was about ethernet... the professor asked why ethernet is used only in local area network? resuming i wrote that ethernet is used only in LAN because it is shared and so for big network there could be a lot problem in using the shared channel.. for istance using protocol such as CSMA/CD, if a big network has a lot of hosts, they could wait a long time before sending...is it right or am I wrong?

View 6 Replies View RelatedI have a computer, the one I am on now, with Ubuntu 10.10, it should be completely updated... and I can network with other computers, I can access Windows XP and 7 shared locations on other computers, and I can also get Ubuntu on other computers to access this computer's shared files.What I can't do, however, is share my hardrives that are on this computer, I have tried sharing them in /media/ and etc, but it is not working, apparently you have to mount them in some mystical way.
Another problem is getting Windows machines to access Ubuntu computers on the network - which I believe is a Windows problem, so I can figure that out some other time, but importantly, I want to be able to share my hardrives over the network.
If someone can give me some instructions to mounting and sharing hardrives(internal), and even my DVD-Drives, and portable USB devices, would also be fantastic - since, in Windows you can just right click, "share", and it's done.. It is a very useful thing to have, and I don't want to use Windows on this computer anymore, but I have no choice, really, if I can't share my storage to the other computers.

View 2 Replies View RelatedProblem:Your company network has internal only hosts / websites with names that end in .local, e.g.Your freshly installed Ubuntu machine works fine on the network, has internet access, etc. but cannot connect to these particular systems.Testing DNS with tools like dig / nslookup works fine, but normal name resolution with ping / telnet / browsers does not work.Solution:1. Open a terminal window2. Enter the command sudo nano /etc/nsswitch.conf3. Change the following line:hosts: files mdns4_minimal [notfound=RETURN] dns mdns4to this:hosts: files dns4. Press Ctrl-X, Y, Enter to saveExplanation:Ubuntu ships configured to do name lookups for self-configuring networks, based on the AppleTalk / mDNS / Bonjour protocol. In the configuration shipped for the resolver, this protocol is considered the final aurhority for the ".local" top level domain, and DNS will not be checked. The above configuration change eliminates this and restricts lookups to (a) /etc/hosts file, followed by (b) DNS
View 1 Replies View RelatedI 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 was able to establish the network and i have connection to the internet. The suse-machine is rechable by ping from all the other computers in the network. If I'm tryiing to ping the other computers from the suse-machine, nothing happens. The router responds without packet loss, but every other ping occurs in:
From 192.168.2.6: icmp_seq=2 Destination Host Unreachable
From 192.168.2.6: icmp_seq=3 Destination Host Unreachable
From 192.168.2.6: icmp_seq=4 Destination Host Unreachable

I've been searching for some ideas to solve this problem but couldn't find any.
I go to system > preferences > network connections in 9.10 and import a profile. The vpn seems to connect but I cannot ping computers on the remote network. When I attempt to ping, it seems it can see an ip (DNS must be working) but I can't actually ping the machine or rdp in. I've disabled my firewall and rebooted and that didn't help. What can I do?
View 3 Replies View RelatedI'm trying to pass multiple dpmains thru one ubuntu server to various hosts on my local network.
[url] should be sent to the /var/www folder on the local host.
[url] should be forwarded to an IIS box on my local network (owa.nunya.local)
[url] should be sent to another ubunto box on my local network (smtp.biznet.net)
I have tried placing VirtualHost entries in /etc/apache2/sites-available/default and [url]and [url] both work but [url] gets forwarded to the c:inetpub folder on the IIS box.
This applies to my 2 opensuse PC's, my Windows PC is fine.I can ping a hostname, say "PC1" but I can not ping PC1.domain.local (even the host PC can not ping it's own FQDN). When I ping just the hostname the ping stats even list the FQDN.Onto the next issue, since all my PC's, have the domain prefix domain.local, my Synology can not. I can ping it's IP and that is it. I can resolve it's name with nmblookup just fine tho and that is what is killing me. How is this not resolving.Even weirder, I can browse to "Synology" in Network Servers under places on the slab.
View 3 Replies View RelatedI have a mac and an openSUSE box connected wirelessly to a router. From my mac, if I ping the Linux machine by both ip address and hostname "elmo.local", I get a response. If I ping my mac from the Linux machine using its ip address, I get a response. However, if I ping the mac from the Linux box using its name "kermit.local" - nothing!
This means in order to share files between them via the network, I have to use the ip address rather than name, but I'd rather not. When I had Ubuntu installed instead of openSUSE this all worked fine out of the box, so I'm assuming it's a problem with the setup of openSUSE rather than the router or the mac.

View 1 Replies View RelatedI would like to experiment a "green" idea of virtual desktop where multiple users are served by a single powerful machine.
I have a server running 24/7. The monitor of this machine is turned off most of the time and the OS is on the login screen.
Other users, in the same local network, use less powerful machines, which could be a thin client or an old Pentium 3 machine. They access their accounts remotely and work with the GUI as if they were sitting in front of the server. Each user sees their own desktop (different themes, screen resolution, etc.). And of course it can happen that several users could log in at the same time.
The usage is modest: mostly web browsing and the usual default applications (office, wine, gimp, etc.). In particular no games or any demanding applications. The users want to use their desktop in graphical mode only.
Question: How do we call this way of using a server? Is it possible with Ubuntu? And how to implement it?
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
since upgrade to suse 11.3 every time I reboot pc the file /etc/hosts is reset to default value. I am a web developer so I need to put in there my aliases for 127.0.0.1. It is annoying to do it again and again. Luckily, I don't restart my system very often but still I would like to avoid that.What should I do to stop this resetting? Or is there another place in 11.3 where should I put my entries?

View 4 Replies View RelatedI 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 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.
When I converted to OpenSUSE 11.2, and went through YaST HTTP Server Configuration, creating my virtual hosts under the Hosts tab, YaST combinedm all int ile,"/etc/apache2/vhosts.d/ip-based_vhosts.conf".I did google and read, [URL]for further assistance.I'd like each virtual host to have its own file under vhosts.d, and wondering why YaST did not do that.The file /etc/apache2/httpd.conf laid out the file structure, and all vhosts.d/*.conf files are included.Is there a way to tell YaST to create separate files for each vhost, or does the user have to manually do it?
View 5 Replies View RelatedI 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.
View 4 Replies View RelatedI 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?
