While using Ubuntu two other computers lose their connection. One (main) is connected to the modem, other from the switch to the wireless router, and the one with ubuntu wired via switch. Currently connected with Windows 7, other two are connected. Once booted into Ubuntu rest of the computers disconnect?

- CAN connect to other computers - ssh and vnc over the home network (via D-link 524 router).
- CAN get an IP address via DHCP
- CANNOT get internet connections - including router at 192.168.0.1
- CANNOT even ping router (but I get an IP address - weird)
- Other computers on the network CAN access internet
- Live CD could not access internet
results of ifconfig
Code:
Code:
I am wondering if his ISP could be doing this - he has received a warning letter about bitorrent. Could the isolate a single computer behind a NAT router?
This is the results from dmesg:
Code:
I have tried:
- to set proxy settings as "Direct internet connection"
- disconnecting power to (including 30 sec wait): modem, router, computer + unplugging ethernet from computer
- Live CD (he only had an old one 7.10) which also didn't connect to internet, but as I am remote, I couldn't do any more. We are downloading a 10.04.1 iso for him to burn tomorrow, and will try that again.
- Uninstalled Crashplan which was the last software that we installed (and it was working ok).
I am currently ssh'ing into another computer on the network that IS working, and then ssh'ing into my Dad's computer - including a VNC session (tunneled through both machines and router).

I have an old HP pavilion laptop (2005) that was useless.I installed Ubuntu 10.10 on it and it became a working computer again. It was excellent, snappy, it was as if I had bought a lower end modern laptop.Internet was working great.I did not have any complaints (in fact, I thought that a modern computer running Ubuntu would beat my so adored macbook, speed wise). For some time I had 2 efficient computer, a macbook and the hp with the Ubuntu OS. So on the last weekend of February, my internet got extremely slow on both computers. After that annoying weekend (February 28) the internet on my mac was good again,however, the internet on my linux continued to be messed up.I tried disabling IPv6 on my machine and on firefox, tried the openDNS, the MTU stuff, but nothing.I even formatted my disk and installed ubuntu again (all this using the installation CD).However, apparently the installation CD uses some of your existing configurations (for example, the layout of the close, minimize,maximize:menu buttons on the corner of windows did not go back to default). So I'm guessing whatever was messed up with the computer didn't change back to default or the previous configuration when I first installed ubuntu. To give you an idea of how slow the internet is, installing alien (terminal installation),I got low speeds of around 150B/s (no typo here, it was bites, not kilo bites) and the fastest around 5,000B/s. The fastest I got was downloading chrome at 6kB/s but that didn't last even a minute. So given that these transfer rates are obtained both on firefox and the terminal, I'm assuming it is not a browsing problem.
A thick headed solution, would probably be to install windows again to get the network configuration to "standard" and then install Ubuntu formatting the disk again (using the CD).I'm using ethernet,so,thinking it might be cable problems, I did try to use the cable that was on my mac on the machine with linux. No success there.

If I have a desktop with a USB wifi adapter connected to the internet through an ethernet cable, is it possible to create a wireless network using the adapter that will allow other users to connect to the internet through mine? I'm in a fairly low-tech place for the next few weeks and getting a router isn't likely.
If it's possible, anyone have links or instructions for how to do it?

I have an old laptop with wireless, 2 desktop computers without wireless and an Allied Telesyn gigabit ethernet switch (specifically AT-GS908GB). Is it possible to hook the 3 computers into the switch and use the laptop's wireless as the internet source for the other 2?

I have internet on my ubuntu machine (eth0) I am sharing with (eth1) My windows computers are getting IP addresses via DHCP from the Ubuntu Machine, and I can see (and use) samba/windows shares on all computers. Internet connection is not working on any of the windows computers.
I have eth1 set to "shared to other computers" under the IPv4 settings

Trying to share my internet connection with other computers on my LAN. I've tried doing this with Debian, Ubuntu & Fedora so far...
My Intended Setup is as follows;
The Problem: So far I've not been able to get an internet connection from any computer connected to the HUB. I currenty have Fedora 13 on PC1 but have also tried with both Ubuntu 10.04 & Debian Lenny. I am open to using any Linux based distro on PC1 as long it has a Gnome Desktop. eth0 on PC1 can be Static or Dhcp, but I would prefer to set Static IPs on eth1 & all of the Client PCs
To the best of my knowledge I have enabled ipv4 forwarding in sysctl.conf (& some other changes);
Code:
All changes I made to the Firewall (all other Firewall settings are still at default, no custom rules added yet);
Router is set up to assign dhcp from 192.168.xxx.100 & 192.168.xxx.200
At the moment I have only 1 PC attached to the HUB. It's Ubuntu 10.04 (PC2)
It's details are;
ip 192.168.xxx.103
netmask255.255.255.0
gateway 192.168.xxx.101
Thus Far I can't ping 192.168.XXX.103 from PC1 & I can't ping 192.168.XXX.101 from PC2. (unreachable) I have an internet connection on PC1 (of course)

The ubuntu computers connect to the internet fine and can ping each other. I cannot find settings to correct.

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?

I would like to set up a remote desktop connection between two computers over the Internet. I already tested remote desktop within a local network but it's far from secure enough this time. I will try to follow this guide [URL] (ssh portforward and internet). This still leaves ufw and how it should be configured. Let's say I have this setup, server computer has ip 12.341.245.124 and the client has 78.12.543.234 how should ufw be configured to be secure? This remote desktop wont be connected to a local network

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.

I set up a server that has dhcp going. This works 100% as I get ipaddresses. My question is how do these internal computers connect to the internet? There is a proxy that needs to be passed as well...
Is this just a simple case of portforwarding or is this a completely different thing?

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?

I successfully installed Ubuntu 10.04 on 2 laptops (both are identical in terms of hardware). In addition, I connected both of them (using RJ45 cables) to a switch (just a switch; I don't have a router). Can anybody guide me what should I do / what settings should I specify in each laptop in order to be able to SSH from one laptop to another?

We have 5 computers networked with 9.04 installed. On some days, when you click on Place -> Network, then all the computers will show. On other days, like today, it does not show. However, one can ping them and I have been able to print to one computer which has the printer attached. SAMBA is installed on the computers for file and printer sharing.

I have a small home network. Computers A and B are both running Kubuntu Lucid. Computer A has an external USB hard drive attached, partitioned ext3 and mounted to a folder in computer A's home folder. Computer C is running Vista. I installed Samba, and computer C can access all the files on both computers A and B. But using Samba, computers A and B can't see each other OR computer C. That's not really important to me, but they can't
So I installed NFS and got computers A and B talking that way. I like NFS better. It's faster than Samba. BUT, computer B can't access computer A's USB drive, and I need it to do that. When I'm using computer B and I click on the folder the drive is mounted to, the file manager just shows the folder as empty.

I'm using Ubuntu on my laptop but I'm having a small problem. The network is working fine except for the fact that I can't reach anything on my LAN (can't even ping the router), but everything on the outside works just fine. I can even visit my webserver if I type my public IP.
Where should I begin looking for faults?
Here, enjoy some data. I'm using my wlan0 interface, not sure whether eth0 works or not.

I want to be able to access my desktop from work so I first set up a DNS. I can ssh into my own computer and using the ip address but when I try to ssh using my DNS (this is from my home wireless which is Linksys E2000), I get the following error:
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug1: Connecting to ****.com [74.79.145.28] port 50000
debug1: Connection established.
debug1: identity file /home/andy/.ssh/id_rsa type -1
[Code].....
I set up the settings on the Linksys to accept DDNS but I am thinking there might be something else I overlooked? I do not understand completely what is happening to debug this. It seems like it initially accepts the connection and then something strange occurs.

I have two desktop computers on the same home network and I am unable to share files between the two. Both have access to the network. One is able to file and printer share using SAMBA and a windows 7 laptop. The other machine is unable to either do file sharing via Samba or SSL file sharing between the two Ubuntu machines.

I'm having some trouble addressing computers by name. I've just upgraded most my my box's to Lucid, and it was all working fine, but suddenly stopped - not quite sure why, or what I did, but I need it to come back! At first I thought it was my old router dying (which it was) but a new router hasn't helped.
I've now moved DHCP from the router to my server, and that's working fine, giving out static IPs from MAC addresses, and so forth, but I still can't address anything by name. My server is on 192.168.100.1 and called myth-server, if I
