Ubuntu Servers :: Provide Internet Access To Multiple Computers Using Only A Hub And 1 Ethernet Port

Mar 18, 2010

Ever need to provide access to multiple PC's and did not have a router only a hub. Maybe this isn't original thinking, but then again maybe you didn't think of doing it this way (which i am sure there are many ways to do it) So I have 2 Ubuntu Servers, 1 Windows Box and a Hub - All 3 with internet access off of single ip and single Ethernet port.

While searching for a backup method today I came across Clonezilla. I was wondering if this was the right thing for me and since I needed to backup my roommates PC for a reformat and install of Windows I decided I would give it a try, but only if it would work. I didn't want the hassle of going into the main part of the house and finding out what cord was what as there is a cable modem connected into a switch (4 static IP's with internet) and one port of the switch hooked to a router) Anyways, didn't work he was on the router I was on the switch)

But this got me thinking. When I setup my server to do this, during one of the setup scripts it said it was setting up Internet access for client machines and that it was assigning them IP addresses threw a DHCP server that it had installed.

So, I dug up the hub connected the internet cable to hub up link and Server 1 on port 1 Server 2 on port 2 and Windows on port 3 The main server gets the internet provided IP address and routes it to the hub via a virtual interface. Server 2 is configured for DHCP and the windows box, It was set to get info automatically but it didn't fill the DNS info so I had to manually do that (just a heads up) I decided to use OpenDNS Servers (208.67.222.222 & 208.67.220.220) but im sure putting in the gateway IP address would have worked too.

So, by now if you need this I am sure you are excited and want to get to it. Like i said there are probably other ways of doing it, ways that don't involve you installing clonezilla and DRBL, maybe even just DRBL is needed, maybe one of them installed whats needed as a dependency- all I know is it works, if you know - elaborate so people know, but hey- this way not only do you have internet access on all PC's you can deploy custom images to them as well.

Ubuntu Networking :: Can't Access Internet On 4 Port Ethernet Router

Mar 1, 2010

I changed to a 4 port ethernet router (D-Link DSL-2542B Adsl2+)with intention to share Internet access with my brother (he's on Vista).Initially it all went well,but 3 days ago there were connection problems occured on the part of the ISP. Without realized the problem,I had reset the router.This morning I've been informed by the ISP that the connection has been re-established.So,I accessed the Internet via the 4 port router but failed to do so (server not found).Suspecting that the problem was from the 4 port router,I reverted to my old Adsl router (DSL-520B single port) and without any problem I managed to access the Internet back.I really need help to configure back the 4 port ethernet router to its initial state.

General :: Home Server - Configure Fedora 15 To Allow Access Via Port 80 From Other Computers

Aug 6, 2011

I am trying to make my home server accessible to the whole web. I have installed Nginx on my Fedora 15 64-bit Linux machine, and it works with localhost but it doesn't work online or allow other computers on the network to access it via the IP address. It keeps coming back with: Could not connect

I have port forwarding. I have even tried different ports but they all seem to be blocked. What could be wrong? I have a netgear router.

Ubuntu Servers :: 10.04 Won't Allow Client Computers To Connect To The Internet

Jan 23, 2011

This is my first attempt at a server, and I running Ubuntu 10.04 server. I had to reconfigure my network, so now I am attempting to use it as a server. I have a Linksys WRT54G2 connecting various machines-- Windows XP, Ubuntu builds, and LinuxMint 10 Julia.

The long and the short of it is that the server connects to the Internet-- I can get updates and install programs via terminal. The server also connects to the router, as tested by pings. The client computers all ping back and forth nicely, and I can access the file share via FTP from the local side and externally (this is part of a larger network).

How can I get it so that my client computers can access the Internet through the router and server?

Debian :: Computers On Network Cannot Access Internet Via Squid Cache / Reolve This?

Jun 16, 2009

I have installed debian to run Squid cache as a caching proxy.
Ive been bashing away now for 2 days and i have managed to install squid (i first tried manually, but that did not work so i used synaptic software packager to install it (from Administration menu)
That went well, thereafter i installed webamin to work with squid in a GUI

I have managed to start squid and added my range of IP addresses to the ACL list
I have added the proxy restriction too.

Now, i tried to test it.
I opened Iceweasel Web browser (on the same machine) and setit to use the Proxy server: localhost and port:3128
That works fine.

But when i try to change the proxy setting to my machines ip (where squid is installed) :
Proxy server: 10.0.0.35 and port:3128
That does not work.
Am i missing something, please help
I then tried to set another windows PC on the network to:
Proxy server: 10.0.0.35 and port:3128
That also does not work.

I also edited the conf file to http_access allow all, but i do not know if i have doen it correctly, but maybe there is another problem?

Ubuntu Servers :: Access Restricted To Select Computers Not Users

Apr 21, 2011

I want to configure a remote internet facing server as git server. I would like to restrict access to the server to a few systems (access is restricted to select computers, not users). I first thought of using ssh key, but the key can be copied to another system hence that alone is not sufficient. I am having a dynamic IP, so simple IP based firewall blocking is also not possible. I was thinking about the possibility of using both SSH Key and IP based access. Is it possible to update the firewall rule whenever my ip gets changed?

Ubuntu :: Use Multiple USB Drives To Provide RAID ?

Dec 14, 2010

I've got a 10.10 installation, which I am using as a media/download server. Currently everything is stored on a 1TB USB drive.With the costs of disks falling, and the hassle of trying to back 1TB up to DVD (no, it's not going to happen) I was wondering if there's some linux/Ubuntu utility, which can use multiple disks to provide failover/resilience ... Could I just buy another 1TB drive, and have it "shadowing" the main, so that if one goes, I buy another, and then restore from the copy ?

CentOS 5 Networking :: Can't Access Any Port From The Internet

Nov 28, 2010

1. I've just installed Centos 5.5 on a dell machine with 2 network interfaces, and have disabled SELinux.

The output for the command sestatus is: SELinux status: disabled

2. Am I right to think that iptables is not a concern since SELinux is disabled? In any case, the output for the command "iptables -L" is:

Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT udp -- anywhere anywhere udp dpt:domain
ACCEPT tcp -- anywhere anywhere tcp dpt:domain

Networking :: Access Multiple Servers From Outside?

Oct 21, 2010

I have an application running inside our lan on server 192.168.0.1:8080. I have configured gateway firewall to direct all traffic on port 80 to port 8080 on 192.168.0.1. So I can access the application from outside lan. Now the problem starts when the application redirects the traffic to another server 192.168.0.2 according to the input of the users. How can I configure the whole system so that I can access the application running on second servers also?

Ubuntu Networking :: Connecting Two Computers Without Ethernet Or Wi-fi?

Jan 11, 2011

I have two computers, a laptop and a workstation, both running linux (Ubuntu and Fedora).For some reasons, it's handier for me to work from the laptop, accessing the workstation only from remote.At present, I have to connect to the workstation using a very complicated system that implies VPN + ssh passing through the internet. It works, but it would be far easier and faster if I could set up a direct connection between the two computers. Unfortunately, I can't use the ethernet ports or wi-fi (it's a long story why, but I really can't).I own a usb data transfer cable, but I don't know how to use it.

Ubuntu :: Share Internet From 1st Ethernet AND To 2nd Ethernet And Wifi Card?

Feb 8, 2011

I am basically wanting to use my Ubuntu 10.10 computer as a router. Note: Before you say just get a router please note that I am poor/cheap. I have two ethernet connections and one wireless connection on my netbook. I want to share the internet connection that is going into one of the ethernet cards through the other ethernet card and the wireless card.

DSL-->1sr Eth --> 2nd Eth (currently works)
DSL-->1sr Eth --> Wireless Card (Adhoc) <--(connects with limited connectivity AKA no internet)

The 2nd Ethernet card already has working internet, but when I connect to the Wireless card (through an Adhoc network), it cannot get an IP (I believe).

Networking :: Ethernet Port Connection With An E1/T1 Port

Aug 30, 2010

i have an embbeded hardware that uses bootp for booting from a Network Managemnt Host (NMH)on the same ethernet. The embedded hardware has both kind of ports i.e ethernet as well as E1/T1. I would like ask, what do i require to establish a communication-link between the embedded hardware and the NMH throuh E1/T1 ports of embedded hardware, so as to make it boot through from E1/T1. Further, NMH possesses only ethernet port. Just to refine my questions i'd like to know what additions do i need to do on my NMH , like may be i have to put an E1/T1 port or is it possible that the E1/T1 port can be directly connected to an ethernet port on the other host.

pardon me if i am not making absolute sense here as my knowledge is limited on Layer 1 and layer 2.

Slackware :: File Sharing Between Computers On The Same Ethernet Hub?

Jun 16, 2011

I have 3 computers connected via an ethernet cable to the same ADSL modem. Each has its own internet address and what appears to be a local address (10.1.1.1, 10.1.1.2 etc).

I would like to enable file sharing between the three but I don't want one of them to be a gateway for the others and I don't want any information that the 3 computers share to go out on the net.

So far, the slack book and man pages imply that years of research are ahead of me and none mentions a "gateway free" configuration.

Ubuntu Networking :: Corporate Network Login - Dont Provide Root Access

Sep 26, 2010

In my company, they provide linux machines which has a 4 yr old Gentoo linux. Also the OS is loaded through Yukon PXE/netboot environment, and the users directory is mounted from an network location. Also they dont provide root access in these machines.

I would love to use the latest Ubuntu in this machine. Please let me know if it is possible to configure a ubuntu/xubuntu in this machine. I need to be able to login with my corporate user_id/passwd, because many of the tools use this for authentication. so just doing a ubuntu installation in this machine and mounting the n/w location would not help.

OpenSUSE Network :: Port Redirection - Multiple IP Addresses - Or Run On Port 80

Apr 7, 2011

In SuSE firewall0. I do have a openSuse 11.4 and multiple IP addresses on eth0 interface

I run (trying to/have to) multiple TOMCAT servers.

I am trying to have each tomcat instance listen to on separate IP address for example:

What i am trying to do is to redirect

a) tomcat 1 -

a) tomcat 2 -

And so on.

I know that it has to be possible.

I do have just eth0/

Is is it possible. Do I have to create "vittual interfaces"? eth0:1, .......... and do redirection ?

"Server" has got just single interface - just 1 ethernet calbe goes to that server. I am planning to have 10-15 tomcat's on that server (I have to unfortunatley) and each has to run on port 80

Is it possible to "grant" permissions to normal users to run app on port 80 - that would solve me lots of problems if impossible to redirect.

I tried to setcap 'cap_net_bind_service=+ep' /path/to/tomcat ...... but no luck
