Networking :: Use Unrestricted Computer As Gateway
Mar 26, 2010
I am having some strange requirements. In my office we all are suppose to use internet by proxy. Squid is installed as proxy. we are given a username and password, that we are suppose to authenticate our selves before we can use internet. But tell u some rules are very bad, like we can not download file from net larger than 3MB,etc. Squid is configured with strict policy. Now, for R & D purpose I am having root access to an unrestricted computer, which is connected to Internet directly. and there is no such limit, as I can use wget to download files of anysize on that machine. It uses fedora 10. I am using fedora 12. Now is there any way I can configure these two PC to use unrestricted net. I mean can I configure my pc to use Internet via that unrestricted pc. What are the changes I will be needed to do at my PC and other open net PC? I am having root access to both PC.

I have a gateway computer that I've been trying to fix up - whenever I try to install Windows XP/2000/Ubuntu, it finds a bunch of errors. I'd really like to get this computer working, it has a 300GB HD, TV inputs, USB ports out the wazoo, and all that other good stuff. Can someone help me with what to do or have a suggestion on what to replace?
I have formatted the hard drive (the Windows installation did it.) The windows installation is to the point where its copying the installation files to the disk, then it gives me an error that it can't find/can't copy the file. The Linux installation just gives me cryptic errors before it even does anything.
I just want to get it to a point where it's usable I really don't care what operating system.

I have Ubuntu 10.4. My computer is connected to AT&T U-verse on a 2Wire brand Residential Gateway. The RG has the actual IP address. It's assigned my computer the address 192.168.1.66. I want to run the apache server to share files between my two computers across town. My other one is directly connected to the internet with a DSL modem so it's IP is static and was easy to set up and get going. What I want to know is what do I type to access my apache server on my RG? Galactic newbie here.

And I'm currently working on a new CentOS 5 install I've made on a computer I've got.. So I'm now trying to get that computer to reach my home network through one of my other computers, which have got XP installed. I've configured the XP computer to act as a gateway from one network card to another, and It works with another XP pc, but no luck with my CentOS 5. I used this link [URL] And I configured the correct network card.
So.. the IP of the XP machine is 192.168.1.70, which I have set as a static. So that the CentOS will find it. And I've connected the (fully working) network cable correctly.
What do I have to do?
I have configured the CentOS to recieve an IP dynamically. (dhcp).. Might that be the problem? (well.. one of the problems.. I've tried to set it to static.. ...?)
Is there more to it than this? I mean when I'm working on communication through an XP machine... ?

I am trying to completely switch to ubuntu as I am encountering viruses on a daily basis here in China and I'm sick of it. My problem is that I need to use a VPN to access unrestricted internet from here. The company that I buy VPN service from has pptp and l2tp but the pptp is too detectable by the great firewall and is unreliable at best.
On xp I am able to set up a l2tp connection directly using just ip address, username and password. Is there anything in ubuntu that I can use so simply? Everything I have looked at so far wants me to have a shared key or a certificate.I'm probably missing some important point which will make it work, but until then I'm stuck with xp and viruses galore.

I am wanting a computer with an external dialup modem (ppp0 modem through a com port /dev/ttys1) to act as a gateway to the internet, forwarding internet traffic through ethernet (eth0 is set to static 192.168.2.2) to a router (the router is 192.168.2.1) where it will be broadcast to other wireless computers like my laptop (192.168.2.3). I've had this setup until recently when the gateway computer (the one with the modem) died. Now I'm replacing that machine with another box and an install of Ubuntu 10.10 but so far things aren't working for me.
Success so far:I have dialup access working on the new box. Took me a while to work out the configuration for getting dialup working, though the IP address is Dynamic (or it won't stay connected), "Check carrier line" is off, and "Ignore Terminal Strings (stupid mode)" is on in order to successfully connect and stay connected to my ISP. I also had to make my normal (non-root) user "lancer" a member of the "pid" group (the reboot) in order to use gnome-ppp as non-root. The laptop (192.168.2.3) is successfully connecting to the router (192.168.2.1) as I can see the router configuration page when I type http://192.168.2.1 into the laptop's web browser. This setup is unchanged from how I had it before when this was previously working and I don't want to change how the router itself is set up. What I want is to know what to fix in the new box in order to get it connected to the router (through ethernet) and bridging the internet through.
My problem is that whenever I plug in the eth0 from the gateway (192.168.2.2) to the router (192.168.2.1), Ubuntu's automatic plug-me-in network detection kicks in and I find my dialup no longer working through some kind of IP conflict (at least that's what I think it is). Maybe I don't have the "gateway" correctly assigned? (in the gateway computer for the ethernet connection, I had it pointing to itself as I don't know what to put for "gateway IP" as that is automatic So, just to check my connection, here I am pinging google (from the gateway computer which has the dialup modem) once a dialup connection has been made.
Code:
lancer@lancer-desktop:~$ ping www.google.com
PING www.l.google.com (74.125.237.17) 56(84) bytes of data.
64 bytes from 74.125.237.17: icmp_req=1 ttl=55 time=179 ms
64 bytes from 74.125.237.17: icmp_req=2 ttl=55 time=176 ms
64 bytes from 74.125.237.17: icmp_req=3 ttl=55 time=158 ms
[Code]...
What do I need to do in order to make Ubuntu of my gateway computer stay connected to my dialup but also simultaneously share an ethernet LAN to my wireless router and feed traffic to the other computers from there? I have googled this but some of the most promising instruction (e.g. http://www.ubuntugeek.com/sharing-in...in-ubuntu.html) call for packages like dnsmasq or ipmasq which seem defunct now in Ubuntu 10.10. Other pages seem to suggest dual-networks "can't be done" in Ubuntu [URL].. (what!?! I had it before my other gateway died)

Someone in my building has placed an old Gateway computer in the trash room. All I know from looking at it is that it says made for Windows XP and its the old tan hue computers use to have. My question is what are the odds that if I go grab it before trash day I could boot up Ubuntu 10.10 or some other current Linux build on it? I just want to use it as a secondary computer and solely for web browsing and possible word processing.

I'm currently viewing all my video and DVD stuff on two different desktops (CentOS and Kubuntu), each with a combination of MPlayer and VLC. Now I'm considering doing everything only with an "MPlayer-on-steroids" build for Slackware 13.37. Basically, I like the one-app-per-task approach. But first things first.
1) I'm basically using this script here as a starting point for my build: [URL]
What libs (from slackbuilds.org) would be reasonable to include before the build to support playback of the most common - and the odd exotic - video formats? The thing with MPlayer is that ./configure --help spits out a gazillion of options
2) Until now I've only used the no-GUI version of MPlayer, since the default interface seems to me almost unusable. Now I understand there are several new frontends available for MPlayer. Is there one that works OK for DVD playback, e. g. enables you to select chapters, languages and subtitles without having to jump through burning loops?

I am trying to get a Linux (Slackware 13.37) working in a Windows networking environment. The IT support for this organisation does not extend to Linux support, so I'm limited in what help I can get for this.
I'm trying to get to the point where I can get to the internet to download what I need on this Linux machine.
The situation is this (*fictitious addresses used) -My Linux machine uses a fixed IP address (10.100.150.21)
My Windows machine uses a DHCP assigned IP address (10.100.150.213)Both Linux and Windows machine are configured to access the gateway server (10.100.150.1)So, I can ping the Linux machine from the Windows machine and vice-versa.I can ping the gateway machine from the Windows machine.I can browse Windows Shares on the network via SMB from the Linux machine.I CANNOT ping the gateway machine from the Linux machine with the Destination Host Unreachable message being the error message.
For actual internet access I need to access a proxy server but since the Linux machine can't even ping the gateway server, it fails to ping the proxy.Now, I have been told the gateway is a HW based router and for Windows machine they use some software for authentication to connect to the network. This software isn't available for Linux, so that's why I've been told to use a fixed IP address.My experience of networking is pretty basic and most of the Linux setup is done via running Slackware's setup program.

I've rent a server from a Germany data center,They use a single IP as their gateway that is not in range of my servers IP,Strangly server is working well and when I use 'route -n' command the gateway which is in other subnet appears properly./etc/sysconfig/network contains no gateway IP and I don't know how they set the default gateway while after reboot the gateway is the same, also the IP is static and there's now DHCP.I need to know how they did it so I can do the same on my VPSes.

I set up a dhcp server in the lan and assigned static ips to two computers, computer A and B, according to their mac address. Everything was running fine. But when I turned off computer A, connected computer C to the network, and assigned computer A's static ip to computer C without changing dhcp setting. Computer C was able to access the internet. When I turned on computer A, dhcp couldn't assign an ip address to it, and computer C showed an error message of ip conflict and failed to use internet. I wonder if dhcp server is able to prevent other computer from using the same static ip that is already assigned to a computer according to its mac address.

My wifes networked computer connected to the network just fine when it was Win XP. Now that Ive converted it to 10.04 (completely) it can see the network, but it just wont connect to it. I had no problem converting my computer to Ubuntu and it sees the network and accesses it great. Files, folders and hard drives are all shared. So, one computer connects great, the other does not.**I dont know what to do at this point.Here is the layout:My Comp (10.04) ---------......Main Network Comp (XP)Wife Comp (10.04) -------/The main network computer is XP as it has software on it we need that does not work in Wine. The main computer will have to stay XP. I cannot get my wifes computer to connect to the main system, although mine connects just fine. I dont know what the problem is. Her computer sees the network, but when trying to connect, it times out and says unable to connect.

FTP is not working through a gateway and I think I found that I need to modprobe ip_masq_ftp. However, when I do try to load ip_masq_ftp I get the error: FATAL: Module ip_masq_ftp.o not found.My question is: how do I get ip_masq_ftp?More questions: Do I have to build a new kernel? If I do need to build a new kernel do I just include the ip_masq_ftp module or are there other modules that I need?

What i need to do is setup a gateway with 2 red networks, reason being 1 is my internet connection and the other is my bDSL connection for our IP phone system and i need an IP range of traffic routed to the bDSL rather than internet, i can do this on individual PC's but id like to do it at the firewall level so i dont have to configure each machine on the network.
basically i want all traffic to go to internet except for say 203.x.x.x which i want routed to the bDSL router and let it handle it. Ive dome some reading and it seems ipcop and smoothwall cant do it so i was hoping with some tricky work maybe i can get ubuntu to do it for me.

I can ping my IP, and other PC in the same LAN, but I CANNOT ping the gateway on my 10.04LTS ubuntu. Other PC in the same LAN(Ubuntu 10.04LTS) could ping the gateway and my IP. I thought that (1)network cable is OK because I could ping the other PC in the same LAN.(2)Gateway is OK because other PC could ping it. (3)setting of operating system might be somehow wrong.
I have tried to restart the network several times and still not works. I followed the HOW-To debug tips and following is the results. Any suggestions?
1. ifconfig

Theres my setup:-
Server:
Both eth0,1 are running dhcp (two scoopes) that works fine!
The output of route -n is:
I have ip_forwarding on aswell, but i can ping the ip on the server running that dhcp scoope ie ping 192.168.4.1 works great but i just cant get the internet on the clients.

a wireless router (box) is went stuck, I found that when it is stuck it uses strange IP local address remote address 10.112.112.112, today is also went stuck but this time the gateway was 10.112.112.112. I had to switch off, switch on teh router to function properly. I am using DSL connection normally the gateway is likie that 78.8.... and my IP (dynamic) like 78.8.240..... Is there any default meaning of 10.112.112.112 in teh net connections?

eth0 is 192.168.0.101, eth1 is 192.168.1.100 (different subnets).
But when I try to make eth1's default gateway the same as eth0's, see the error I get code...

recently i have combined 2 machines into 1. after doing this, the ping to the new machine stops, for no apparent reason, and consequently all traffic to/from the machine also stops. when using the two machines individually this never happened.Lastly, if i restart the network, it kills everything (like the network just wont restart - it reaches the last interface and hangs), and if i reboot the machine, it seems to be fine for about 3-4hours.has anyone seen anything like this when connecting a large number of hosts to 1 gateway, using linux as the router?

Our firewall (debian) currently has 4 public ip addresses (eth0 1.2.3.4, eth0:0 1.2.3.5, eth0:1 1.2.3.8, eth0:2 1.2.3.9) and 3 internal subnets (eth1 10.1.x.x, eth1:0 10.2.x.x, eth2 10.7.x.x). We are experiencing the following two problems which I believe have the same root cause. 1) The firewall cannot access beyond the isp gateway (1.2.3.1). 2) From externally, we can ping eth0 with no trouble, however, pinging the eth0:0, eth0:1 and eth0:2 interfaces have results similar to the following:
Code:
PING 1.2.3.8 (1.2.3.8) 56(84) bytes of data.
64 bytes from 1.2.3.8: icmp_seq=2 ttl=57 time=59.0 ms
64 bytes from 1.2.3.8: icmp_seq=2 ttl=57 time=63.0 ms (DUP!)
64 bytes from 1.2.3.8: icmp_seq=13 ttl=57 time=59.3 ms
64 bytes from 1.2.3.8: icmp_seq=13 ttl=57 time=63.0 ms (DUP!)
64 bytes from 1.2.3.8: icmp_seq=24 ttl=57 time=62.0 ms
64 bytes from 1.2.3.8: icmp_seq=24 ttl=57 time=65.6 ms (DUP!)
I get the feeling that I'm missing something obvious, especially since all traffic on the internal subnets can access externally as normal.

I got 2 servers, each on different locations (server 1 and server 2). I want all traffic on server1 included web browsing, applications etc., be always going through server2, like a gateway. I want the traffic to be encrypted (maybe use VPN?) So if I browse, or any logs pick up ip adresses from applications used by server1, I want it to display the IP address from server2 (Might be the wrong way to say it).
I always wants server2 to act as an firewall and logserver that logs all the traffic. I was thinking about using Snort for IPS/IDS solutions and OpenVPN for the traffic, but what can I use as a firewall? Most firewalls I find on google has its own OS/Distribution. Maybe Squid for logs? But squid does not support much protocols. Distribution on both servers are updated Debian/Ubuntu based.

I am using Fedora 10. I have a network design like that:
WinServer --- (r1)router(r0) --- (eth1)LinuxPC(eth0) --- intranetPC
All netmask is 255.255.255.0
WinServer network is 192.168.1.0/24
intranetPC network is 10.10.0.0/24, gateway is IP of the LinuxPC(eth0): 10.10.0.2
Router:
r1 -IP: 192.168.1.253
r2 -IP: 10.10.0.253
LinuxPC
eth0 -IP: 10.10.0.2
eth1
-IP: 10.10.0.40
-GW: 10.10.0.253
I search in Internet several days to find how to configure the LinuxPC to a gateway. The LinuxPC can ping and connect the WinServer and intranetPC correctly, but the intranetPC cannot ping and connect the WinServer network.
I used the webmin to configure the Gateway.
I used the iptables to set allow all connect, than
iptables -t nat -A POSTROUTING -eth1 -j MASQUERADE
iptables -A FORWARD -i eth0 -j ACCEPT
echo 1 > /proc/sys/net/ipv4/ip_forward
In "/etc/sysconfig/network" add "FORWARD_IPV4=true"

There are a lot of boxes in this network and we have intranet site. If I connect computer directly to the network with everything set to automatic. I can see this intranet site. But I've installed a switch. One box has two net adapters and it takes internet, intranet and all from one adapter, the other adapter is connected to switch. Now, I have connected to this switch two computers. Internet is working fine. But I cannot get to this intranet site from these boxes. I can get into shares of other computers in the network but they cannot see me. Everything is hidden behind the gateway. But that's not the problem for me. All I want is to get to this intranet website. How can I do it?.
