OpenSUSE Network :: Create A Gateway Server That Allows Virtual Private Network Connections?
Feb 26, 2010
I have openSUSE 11.2 installed and i need to create a gateway server that allows virtual private network connections. I want to play with my friends some lan games, but we are in different networks, so i want to create this gateway server so we can connect with VPN clients to this server and play freely.
My ISP has for a long time had a broken forward/reverese DNS so that my ADSL connection with static IP address resolves to a completely different IP address on a reverse query. This has not been a problem until I upgraded a remote server from 10.3 to 11.3 last weekend and now ssh connections from my ADSL connection to it using public/private keys are being rejected with the following message in /var/log/messages (IP addresses changed): Aug 10 12:00:32 penguin1 sshd: Address 22.214.171.124 maps to 83-175-246-243.static.dsl.aupex.com, but this does not map back to the address - Possible Break in Attempt!
But if I log in interactively with username & password, the connection succeeds. I've changed the StrictModes setting in sshd_config to 'no' but this hasn't resolved the problem. Obviously something in 11.3 is being stricter about this IP mismatch than it was in 10.2 (and no, the server is not using a firewall). There must be something I can change to make sshd more permissive? I've tried before to get my ISP to fix their problem but no luck. This needs to be sorted as a server at my home (which does not run SuSE) retrieves backups from the remote OpenSuSE 11.3 server every night using scp and these are now failing.
I have users using Windows XP, Windows 7, Linux (Fedora) and Mac. They all are in a single private network and all access internet through a Linux (RHEL5) system in which Squid acts as gateway. The same is true with my branch offices too except that private network is different and gateway system uses Fedora 9 instead of RHEL5. All the branch offices are connected through point to point leased lines with the head office for file transfer.
My requirement is this: I have a web server located at head office. Presently I am able to access this server from my branch offices through internet. I would like to access this server from branch offices through leased lines. This too I am able to access if I do routing in users system. The file transfer is taking place through one to one system at two ends by creating static routing in those systems.
Well to make this straight forward as possible I want a program like The Hotspot Shield In Windows and Mac, Its uses's VPN (Virtual Private Network). To view Hulu (And other stuff). A link: [URL]. Or can I use it wine (I don't really think so, by the way I didn't test it out Because its blocked in my country).
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.
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?
I first tried an upgrade from 11.3 to 11.4 and lost Internet Access, so i re-loaded 11.4 from scratch on clean partitions.
I am connected to my wireless WPA2/PSK connection, have an IP, am able to see the network.
I turned off and disabled the SUSE firewall.
I tried setting Firefox proxy settings to auto and to none, i dont use proxy.
I am currently posting this through an SSH connection to my 11.1 server from the new install of 11.4 on a Dell latitude D600 laptop (not using the on-board Broadcomm that is an issue for a later date).
I had a google of this but can't find anything useful. I use networkmanager to configure my wireless card. Currently this only works when I'm logged in to KDE. If I log out the system loses the network connection. Is there a way to make it persistent using NetworkManager?
I just finished a fresh install of 11.3 on an HP 7900 small form factor and have no network connectivity. In Network Tools eth0 shows the state as inactive. Network Connections didn't have a connection, so after letting it create one there is no MAC address. I copied and pasted the MAC address from Network Connections eth0, set up a static address with default gateway, netmask, etc. all set appropriately and rebooted. Still no joy.
I want this to get an address via DHCP, I just set up a static address for testing.11.2 sensed the NIC without issue, but 11.3 doesn't seem to like me right now.I wanted to get this deployed on 40 machines today. Oh well.
I remember when using openSUSE 11.3 with KDE 4.5, the network connections started to show the last date used for my "NIC".I am using the plasmoid-networkmanagement plasmoid and KNemo.After I downloaded and installed openSUSE 11.4 64-bit, the network connection no longer shows the last date used. I have set up my card via Yast and Iam connected directly to the Internet. No proxy.To find where this is located, navigate to:Configure Desktop --> Network Settings --> Network Connections --> Wired tab.
First a warning that I'm so clueless it hurts. Initially I entered the Linux world as a solution to my blue screening Alienware Aurora desktop (which later fried anyway ironically enough). I decided to give up on Windows for everyday use cause you can't strangle an operating system. My first and there after Linux experiences have been fantastic. Internet works without prompting through various distributions of Ubuntu, Mint, and KDE with the exception of enlightenment.
But now I come to openSUSE 11.4 and as my title suggests I'm having a hard time connecting to the internet. I've got a wireless card and router and all that jazz but I can't even select the options for wired or wireless connections under Network Connections in the Network Management Settings. Everything is greyed out except for VPN. I even have the desktop wired to the router and it still is not giving me any indication that it will connect.
I'm wary of trying to enter ip addresses and things of the like because I honestly don't know what i'm doing here.
My router is a Netgear N150 Wireless WNR1000 and in the Kinfocenter under Device Viewer I found my wireless card to be a RaLink RT2561/RT61 802.11 g PCI and my wired device thingy to be an Intel 82540EM Gigabit Ethernet Controller.
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'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?
Fedora 11 I have tried just about everything in webmin, the current one I am working with is openswan, and I get this error: ipsec newhostkey --configdir /etc/ipsec.d --output /etc/ipsec.secrets ipsec rsasigkey: key pair generation failed: "-8037"
My boss would like to have our employees connect to our linux server, then access their personal computers to work when they are unable to be in the office. Everyone else in the office uses winblows and they are unwilling to try anything else no matter what the benefit. The most important one is the CAD guy, we need him to work on drawings from school or his latest flings house and I am just running out of steam. how to fix this error or radically change my approach, I will try or do anything.
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??
My goal is to have users(Unix Users like root on host1) use evolution /sendmail to send and receive emails between users( Unix users either from host1 or any other host on n a private network. The network is a private network with a few servers without any connection to Internet and no DNS. They resolve one another by /etc/hosts. with smtp configured am able to send and receive emails on one machine(host1) from unix user abc on host1 to user xyz on host1 and vice versa. the commad i used to test is host1@abc #echo "this is a test mail" |mailx zyx@host1 But when i tried sending from user abc on host1 to user xyz on host2 its giving error for DNS unable to resolve hostname.
the commad i used to test is host1@abc# echo "this is a test mail" |mailx zyx@host2 create a simple sendmail config so that i can send mails between multiple hosts using unix usernames within one network. I can use one of the server as mail server and rest as clients. I dont want to configure any other softwares for pop or imap access. I want to keep it simple and use evolution on the clients to send emails between one another on the private network without internet.
I just intalled OpenSuse 11.2 on VmWare Server 2.0.2, the network is configured as Bridged and is sucefully configured a fixed IP in my network. Ok... The problem is... I can ping / trace all addresses from OpenSuse console. But I Can't wget all of them... It's a random thing. the same address that trace's ok, don't work for HTTP.
Recently loaded 11.3 onto a virtual machine, however none of the network settings will allow me to connect to the internet. First time Ive had this happen, other distro's Ive experimented with connected with no problems. I recall seeing a similar topic some time ago (dont remember if it was here or another forum), but at the time, there had been no fix. Anyone know if this has been fixed?
I run a server that is connected to several other boxes in a private network (192.168.0.0). I have had no problems previously, but upon a reinstall of Debian squeeze I have no connectivity to the private network: a ping of other addresses on that network fail. Ping and connection to outside world is fine. This box is configured similarly to another on this private network which connects successfully. I have quadruple-checked all my basic information. I post my ifconfig below of the malfunctioning device, then the ifconfig for equivalent nic on a box connected succesfully to the private network.
1.Could it be a cable problem? (I don't see how since the cables have not been changed I do not believe since my reinstallation).
2. What about the difference in the last lines of eth1 below and eth2 of the successful box. Is it significant that the bad eth1 reads Memory:fc3a0000-fc3c0000
The only things i need out of it are: mars_nwe (Netware server under Linux) and a reverse telnet server (the dos machine is a bbs) I need the virtual server to support a very old dos machine, and while i COULD use samba for drive mapping, the VNC server I'm useing on the dos machine is a progrm called TINY which pretty much means i'm stuck useing the novell dos network stack.
how best to configure opensuse for this? I'm running the install off of the live-dvd which has quite a bit selected by default. I'm not in need of an x-server or a desktop manager, as this will be a set it up and forget about it once it works VM
I'm trying to make changes to several computers at once in a private network. I have ssh keys setup so that I can ssh from the main computer to all the other computers without having to enter my password. So I wrote a bash script like for computers in `cat computer list` do ssh $computers #type changes here exit done
but instead of executing the commands on every computer, it opens a shell on every computer for me to type into, just as if I had used ssh myself and not in a script. how to get this to work? I want to be able to add lines at the comment like "echo "test" > /testFile.txt" and be able to see the changes on each machine, in this case see testFile.txt on every machine.
i am totally new to Opensuse and to filezilla. I formerly used winscp - a windows-client for ssh.now i have a linux box and want to connect to the server via ssh ing filezilla.Can i use the same keys as i used in WinSCP - where should i store them and the third question.I read something about a certain so called certificate-file that has to be created!?
