Networking :: Setting Up A VPN For Windows Clients To Reach Debian Server Over The Public Internet
Jan 30, 2010
I'm trying to give some windows users a permanent connection to a samba share behind a firewall over the public Internet. I know I can give them access with something like winscp (which they have done) but really I'd like to do it with a VPN so it seems seamless to the user. However I have no idea how to set up the server to support this and am finding the documentation a bit confusing. The samba share is on a Debian box and the firwewall is a Linksys WRT54GL.

I have openvpn tunnel setup between two CentOS servers. One of the CentOS servers also acts as a DHCP server for some client computers.
Server A= OpenVPN server
Server B= OpenVPN client (connects to Server A with OpenVPN)
The two CentOS servers can ping each other (172.16.0.0/24) via the tun0.
However, client computer connected to Server B (DHCP server) can't reach 172.16.0.1 (which is the OpenVPN server).
I think I am missing some routing in my "ip route show". Following is the full picture:
What command can I issue to get this fixed? something along ip route add?
There is no firewall service on both end. service iptables stop! I can't bridge eth1 and tun0 as DHCP server might mess up the other side. I can't do a push of "redirect-gateway def1" because then clients loose their IP as they send DHCP requests to Server A.

I'm sure this is possible... I'm just not sure how. Yet! I have three machines. One is at home behind my firewall and has a dynamic IP. That's fine as I don't really want to open any ports on my home firewall. The second is at work sitting behind the firewall there- and I'm not even going to ask for approval to NAT an IP to my PC at work :-).
The third is in a data center far away. I only have a shell account on this server but other than that shell account not being root, I can do most anything I like with that account. What I would like to do is SSH to this server simultaneously from my home and work PCs and, via this third machine, make them talk.
This is pure geekery so it doesn't matter what they say to each other; I just want to make them talk. Maybe one uploads a file and the other just pulls down that file. Maybe one opens a FIFO on the remote server and starts writing to it while the other starts snarfing that data. In fact, I like this latter idea best, I think. How would you do it? What scripts (fired by cron if need be since I'm ostensibly away from at least one of the PCs at any given time) would you use?

having trouble connecting to many websites due to recent actions of the Iranian government on banning a lot of websites.That's why, I decided to make my computer act like a bridge for their computers, so that they can surf the web using my Internet connection in US. I have Arch linux running on my desktop. I tried to install OpenVPN based on the instructions at ArchWiki page, but I had no success. I guess OpenVPN is too much for what I want to achieve and ArchLinux repositories don't have all the necessary packages to configure it based on some posts I read.

I've searched through google, and all I can find are instructions on how to set up a L2TP/IPSec VPN that works with macs and iPhones. I'm NOT trying to set up an L2TP/IPSec VPN. I'm trying to set up a pure-ipsec vpn.
The iPhone IPSec client is a built-in cisco client, I believe. I'm staying away from L2TP and PPTP because I need multicast packets to go through. *edit: wow, i just noticed that the title says "8.10 LTS". Oops! I obviously mean "8.04 LTS". Gah, the lack of sleep got to me.

i have successfully setup PPTPD on my server and I can open a VPN tunnel but my clients can only ping the server's IP, they don't have access to the internet through the VPN.
i have searched different forums and understand that I have to create a route on the server to route packets between the VPN interface and my internet gateway, but I didn't manage to get this work.
here is what my setup looks like:
Code:
root@r31495:~# ifconfig
eth0 Link encap:Ethernet HWaddr 00:1c:c0:c7:13:35
inet addr:94.23.197.XX Bcast:94.23.197.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

I use Fed 14. I have China Telecom internet. The wired dsl connection works fine, but the wireless won't work. It has WPA security. The password taken from beneath the router is n2nqrcqx. This password is accepted. Network Manager says I am connected to ChinaNet-TRtk, but in fact, I can't reach the internet via wireless. If I disconnect the cable, I can't get through. I have the settings on automatic dhcp. I have nothing in BSSID, I don't know what that is. I unchecked the box 'require ipv4 addressing for this connection to complete' Ditto that for ipv6.

I used my computer this morning before leaving for the office, but when I returned this evening, I am unable to reach the internet. Also the light on the mobo where the ethernet cable is plugged in is steady yellow.
My limited experience would tell me it is a hardware failure, but it seems so strange with nothing happening during the day. How might I best diagnose the problem from within Ubuntu (10.04)?

host is windows 2003 server 64-bit
guest is ubuntu 9.04 server 64bit
Qemu : 0.11.1
Qemu manager: 7.0
from Qemu manager, if network card is using User Networking, it's a NAT and I can see that Guest Ubuntu has an ip address 10.0.2.15 and is able to access the internet. However, as Guest ubuntu is running server so I want to do use Tap networking and I assue with Tap, the Guest ubuntu will get an ip address which is in the same subnet as host machine by dhcp. so from Qemu Manager 7.0, I changed Network card to be:
NE2000PCI
Vlan Number =0
VLAN Type: Tap Networking
Mac address: tap0's mac address from host
TAP Network Adpator: Tap0
Note that tap0 was created by openvpn. and then fired Ubuntu guest, ifconfig shows no ip address on eth0 (which has the same mac address as Tap0) so the guest Ubuntu has no ip address and can't access public.

I am stepping into Linux world ...and I have chosen CentOS.
I have installed CentOS 5.5 on a dedicated IBM server successfully. My server has two network cards. I have configured eth0 for lease line internet connection with a live IP (113.xxx.xxx.xxx) and eth1 for local LAN with a static IP (192.168.0.1).
Now,
1. DHCP is working fine and I can access the server from my Windows XP clients.
2. I can access the server with SSH client PuTTY from home ( with the live IP ) and from the local LAN (with static IP 192.168.0.1)
3. I can access my shared server directory 'public' from my XP clients
4. Internet is working on sever and I have updated the server with yum update.
But, I cannot access internet from my XP clients machines.
I read "The Definitive Guide to CentOS" and tweaked the config files in different ways but it did not help. now after two sleepless nights I am here as my last hope.
I admit, I am not aware of every linux terms and commands, but I am getting into it. code...

I'm trying to setup a server at home, it has some practical implications, but largely it is just to take a stab at it. But I need the help of someone with more experience than I in defining exactly what I'm looking to do.
Here's what I have: old PC running Gutsy server connected to router. Several laptops at home connected via wifi to router. All laptops running either Windows or Ubuntu. Here's what I'm looking for: The server centralizes file storage for all clients. I would likely incorporate a RAID and some synchronised imaging of the files. I also want the server to create disk images of the clients hdd, regardless of client OS.There would also be some shares that would be publicly accessible (myself and friends accross the country would be able to access the same drive).
So I was thinking something like what corporate environment would be nice, you log into a profile that exists on the server. Like a dumb client...all data would be stored on the server. But I'm thinking that's more like a network boot and wouldn't work via wifi (or would it?). Also that wouldn't lend itself well to laptops used on the road in areas without net access. now I'm thinking each client would have its own locally installed OS, and they would just access networked shares. I could store sensitive files on the shares, but that wouldn't provide complete backup solution for each client.
Without rambling on anymore, anyone care to throw out some ideas? I'm really just looking to see if I can do what I want. The focus is on centrallizing files, securley backing up data and client OS's and ability to restore said images quickly.

I'm running several Ubuntu servers with LTSP thin clients in our classrooms. It's been a royal pain trying to get them to synchronize time properly.Currently I'm looking at 7 client's login screen and each one has different time. It's frustrating and I've done all the reading I could in regard to NTP and LTSP with time, etc.I'm trying to even set NTP to point to an external server, but my thin clients don't get that setting for some reason. They still pick whatever time they want to present to the end user. Once the user logs in, the time seems to be fine. It's just at the login screen.Since I'm no expert on NTP I figured I'd ask to see what users here thought.
EDIT - I was told that the GUI version of Ubuntu handles NTP at System-Administration-TimeAndDate. Is this true? I was told my /etc/ntp.conf file is empty because that file is only used in the server edition of Ubuntu.

The office network has a machine we're using as a fileserver, which is running Windows Server 2003. There are several issues with this, but the main one is that the "Terminal Server License Server" was never installed or activated. I managed to do these things, but to continue requires retail keys which are long since lost. So the boss says we're going to make it into a linux server instead. And by we, he means me. A friend recommended Debian so my research starts here. i have a little experience running an ubuntu desktop at home, using the console quite a lot. And a little bit of experience messing with my own server. however, most of this is new territory for me.
The needs of the organisation:
1. We need a shared directory on the server which all valid accounts can access
2. We need a per-user directory on the server for each user, which only that user or root can access.
3. We need a per-user windows desktop, which only that user or root can access.

I need to grant windows client an access to fileserver. The easiest way to do it is how? Setting up VPN server on Windows server, what rules are going into iptables in linux machine then. Or setting up VPN server on Linux machine (which is the best option) and how the user gets to fileserver?

I just set up my ubuntu 10.10, which boot up by usb drive,
and I found a problem that I can't get my internet when I was
sitting in a public library. The firefox show me every website is
untrust. Normally, when first connect to this network, I need to
accept a library contract on webpage, which called spyder.local.
Does anyone could fix it? or there is something related to the
firefox setting. I currently keep every setting by default

In one of my customers, the new internet connection have no public IPV4(using GCNAT), only public IPV6.
And there are various services that require external access, like, vpn (openvpn), a java/web system, ssh, rdp(windows).
fileServer(by vpn).
All is running ok in IPV4.Maybe, the solution is a NAT 6to4. We know this is the future, no more public IPV4.

I'll state the issue and then give whatever extra details are needed. I'm running Ubuntu 10.xThe Linux box is connected to a router via ethernet. That Linksys router is bridged to an AT&T router.The bridging is working fine. The AT&T router's page shows the IP of the Linux box and lists it as a device. The Linksys page shows no errors with packet transmission and receipt. I can ping the Linux box from any client on the AT&T router, and can ping the AT&T clients from the Linux boxI had set the IP of the Linux box to192.168.1.201 while configuring that router, as I had set that router to 192.168.1.200 and it just seemed orderly.The network preferences show eth0 being set to auto dhcp, but the IP is still set to .201 so I don't know that it actually released or renewed.

I have a linux box (fedora) with two ethernet cards eth1 and eth2. On eth1 I successfully configured a PPPOE internet connection. Such that from the server I can browse the internet. On eth2 I wired it to a wireless router essentially to provide the wireless cloud. On eth2 I also configured dhcp, such that the Linux box is both PPPOE and DHCP server.However my clients on the LAN cannot access the Internet.
On passing the routing command I get
Destination Gateway Iface
196.44.x.y 0.0.0.0 ppp0
192.168.1.0 0.0.0.0 eth2 (my subnet)
0.0.0.0 0.0.0.0 ppp0.
The router (functioning as a wireless access point mainly) has a fixed IP address of 192.168.1.2 and eth2 has IP address 192.168.1.1. The dhcp file running on Linux has been set with option router (Gateway) 192.168.1.1. I cannot figure out how to correctly set the routing table such that my clients on wireless can access the internet cloud. I googled and googled but no solid solution. Any suggestions?

I am running CentOS release 5.6 (Final) and have successfully installed PPTPD and this works great internally.
I want to access my Linux box remotely on the internet via my VPN tunnel. However I am not sure what I need to do on the Linux box to make this happen. My linux box is multihomed as follows
PSTN WWW <===========> ADSL Router Firewall <----------------> [eth1 192.168.x.x] Linux Box [eth0 172.16.x.x] <-----> to LAN
The desired topology is as shown.
VPN Client <------> Home ADSL Router <======= PSTN WWW =======> ADSL Router <------> eth1 Linux Box
1. The VPN is setup and bound to eth1 and eth0 and works well internally
2. IPSec, GRE and PPTP rules have been declared on the router which port map to eth1
However I am still unable to setup a VPN connection to Linux Box I suspect something hasn't been done or I have setup my NATing or IPTables correctly on the linux box.

I'm setting up my server under CentOS 5.5 (text mode) and I installed cherokee server but I couldn't reach it with the ip given by ifconfig. So I figured it might be an problem within cherokee. I also wanted to install webmin so I did that to see if I could reach that one. But also the webmin server is not reachable (I know the port number should be behind the ip ). So if I look up ifconfig I see the server has got an local ip (192.168.1.42) but I can't reach it from another computer in the same local network.

I work for a church, with office staff of about 10 people.
We want to set-up a server to store all the office information, (which is now scattered all over the place).
The idea is to give individuals a partition on the server(password protected). There is database software that needs to be accessed by 5 people( it runs on MS Access). Most of the document are MS Word. Of course you can tell me of a better way to do this than my idea.
how to set-up this network. I have to submit my info to church leadership. it will save us buy Window Server and 10 CAL (that ZAR 10k).
I have copies of OpenSuse 10.1 and Fedora 11.
