  • Connecting Ubuntu home server to internet via laptop

    - by Gray-Wolfe
    I recently got a spare desktop computer from a relative to play around with and since I've been using Ubuntu for a few years I decided to install Ubuntu Server 12.04 to play around with and learn more. However it doesn't have a wireless card, the wireless adapter had a shipping error and will be awhile, and plugging it into the router is not an option. So I figured I could give it access to the wifi from my laptop(which I switch between Windows and Ubuntu) so I could at least get some things started and set up while I'm waiting for the adapter. However the few guides I can find to do that require a GUI, something lacking on the server version. Could someone tell me how to set this up via the terminal? I would appreciate it.

  • Regulating outgoing traffic on ubuntu VM

    - by DazSlayer
    I am making a virtual network setup for my high school cybersecurity team to practice. I am connecting all the VMs together through a VPN and then people who are practicing will VPN in and ssh/remote desktop into the different VMs. The problem is that for practicing, they will need root access into the VMs and because the VMs are connecting to my personal network, the VMs pose a security risk to my personal network. Is there any way in either VMWare or VirtualBox or even making an unchangeable iptable (I can make all the windows VMs go thru a linux VM) to prevent people from connecting to my local network via the VM?

  • Is there a way to get my NETGEAR N900 to work with ubuntu?

    - by user208088
    I'm using a NETGEAR N900 USB Wireless Adapter to pick up our home network connection while running Windows 7. I have Ubuntu 12.04.3 running on a second hard drive in my computer that is not compatible with my adapter. I'm not very familiar with how to work around in Ubuntu yet and this is the only thing keeping me from using it. I've seen this asked before but the instructions were very confusing to me! Help is appreciated

  • Lost connectivity after configuring multiple network adapters on separate networks

    - by Dave Long
    I am trying to setup an Ubuntu hosting server, currently just for development, and the server has two NICs, each sitting on a different network. eth0 is on 192.168.200.* and eth1 is on 192.168.101.* and each one has a static IP. eth0 is the public facing NIC card and eth1 is strictly for internal access to the server. I initially only setup eth0 and added the eth1 card when I needed it. eth0 was working find until I added eth1, now, can't get any connectivity on eth0 unless I pull eth1 out of the box. The configuration on each system is as follows: auto eth0 iface eth0 inet static address 192.168.200.94 netmask 255.255.255.0 network 192.168.200.0 broadcast 192.168.200.255 gateway 192.168.200.253 auto eth1 iface eth1 inet static address 192.168.101.64 netmask 255.255.255.0 network 192.168.101.0 broadcast 192.168.101.255 gateway 192.168.101.254 Again eth0 worked fine until I added eth1. I have seen this happen with Windows servers if you have a Default Gateway setup for both NICs, but I am not sure if this works the same on Ubuntu. My resolv.conf file looks like so: nameserver 192.168.101.59 nameserver 192.168.101.58 domain domain.local search domain.local Per request here is the Routing table 192.168.101.0 * 255.255.255.0 U 0 0 0 eth1 192.168.200.0 * 255.255.255.0 U 0 0 0 eth0 default 192.168.101.254 0.0.0.0 UG 100 0 0 eth1 default 192.168.200.253 0.0.0.0 UG 100 0 0 eth0

  • Wifi works perfectly on Windows, but drops on Ubuntu

    - by alecRN
    I have a dual-boot computer with Windows XP on one partition and Ubuntu 10.10 on the other. In Windows XP I can connect to a hidden wireless network (WPA-PSK AES) perfectly, and I was finally able to install the driver for the adapter on Ubuntu (RNX-N180UBE, hardware id RTL8191SU). It works fine when I first boot the computer and log in, but then after a few minutes the network suddenly stops working completely. If I try to reconnect it, the network manager claims to have connected, but in actuality it's still down. At some points, I have been able to connect to a public network even while the private network didn't work, but that eventually wouldn't work at all either.

  • Asus 1001P freezes after chaging network settings

    - by auntiquarian
    I'm running Ubuntu 11.04 on a Asus PC 1001P in a dual boot environment with XP. All has been running fine for several weeks, but: I've just changed ISP (from Tiscali to BT), and had already sorted out connection, registration, etc. on a Dell laptop. On the Asus I went into Ubuntu to alter the wireless network details (i.e. selected the new network, and entered the password). Ubuntu immediately started running slowly, and after rebooting it now freezes when it gets to the Ubuntu logo and gets no further. Please help, lovely Ubuntu experts.

  • Is it illegal to forward copyrighted content? [closed]

    - by Mike
    Ok, this may be a strange question, but let's start: If I illegally download a movie (for example...) from a HTTP Web Server, there are many routers between me and the Web Server which are forwarding the data to my PC. As I understand, the owners of the routers are not legally responsible for the data they forward (please correct if I'm wrong). What if I would install a client of a peer-to-peer network on my PC and this client (peer) would forward copyrighted content received from peers to other peers? Hope someone understand what I mean ;-) Any answer or comment would be highly appreciated. Mike Update 1: I'm asking this question because I want to develop a p2p-application and try to figure out how to prevent illegal content sharing/distribution (if forwarding content is really illegal...) Update 2: What if the data forwarded by my peer is encrypted, so I'm technically not able to read and check it?

    I just installed Kubuntu 12.04.2 and do not have an internet connection. I also cannot access the Desktop and only have the terminal. When I enter xlcock I get Error: Can't open display:.

  • MacMini (running Ubuntu 14.04) loses wlan connection when uploading larger files (several 100 mb) via ownCloud

    - by ManekenT
    I installed Ubuntu 14.04 on an old MacMini with the intention of running it as a homeserver. Additionally I installed ownCloud and tried to sync some files both from a laptop running elementaryOS and a desktop running windows 7. Syncing smaller files workes like a charm (4000 files at <10mb each) but when it comes to bigger files (1 GB ubuntu iso e.g.) the upload failes after 20-100mb. I can't ping the server anymore and the server can't ping me. It still shows up in our router as connected though. Disconnecting and reconnecting the wlan connection fixes the issue until the next attempt at syncing. Edit: I also had to install the wlan driver with this manual: https://help.ubuntu.com/community/MacBookPro8-2#Wireless

  • Can I set up a hostname alias that is only active in a specific network?

    - by denisw
    I have a small ARM box running ownCloud in my house, and a domain bound to my DSL router with Dynamic DNS. This works well as I can configure the ownCloud client to use the domain name, which works both in the house and when I'm on the road. However, at home I would like to let my laptop and my server talk to each other directly on the local network, rather than as if they were talking over the Internet (including DNS resolution for my domain name, routing all traffic through the DSL machinery etc.). I know that I can set a hostname alias for my domain in /etc/hosts - the problem is that I want this alias to only be active when I'm in the home network, while in all other cases DNS resolution should be used as normal. Is this possible?

My (and my neighbor's) wireless networks shown up, but no matter how many times I tried, I can't connect to my home network. I checked the password and the other laptop's internet works (a MacBookPro). It was a wireless network. What's weird is that the Wireless network worked when I was installing ubuntu How can I connect to the internet now? I don't have a wired network. Please Help!

  • Question Virtual Network and NAT set-up

    - by Jay
    Hi Guys! I need some help. I'm completely new to Linux. I'm trying to set up the following scenario: +-----+eth0 +-----+ +---+ | VM2 |-----------| VM1 |---------------| H | +-----+ eth1 +-----+eth0 (NAT) +---+ VM2 - Virtual machine from Virtual Box, using Ubuntu VM1 - Virtual machine from Virtual Box, using Ubuntu: I want this to act as a NAT. H - Host, my Windows Vista The dots were just added since after saving the spaces disappear. So if I ping H from VM2, H would receive a different IP address from VM2. Could you give me a step by step on this? All machines are of course 32 bit. Thanks. Would appreciate the help so much.

  • Network Computers Not Showing up

    - by Muhnamana
    Alright, 3 machines running, two using Ubuntu 11.10 and one on Mac OS X. On the two Ubuntu machines, both have samba installed and configured on the same workgroup, "HOME". On machine 1, I can see all networked machines. On machine 2, I can only see the Mac OS X machine. It doesn't show the other Ubuntu machine. What am I missing on machine 2 to see all networked computers? Any suggestions are welcome. I'm pretty much stumped.

  • Network disabled on some wake-ups on saucy laptop

    - by Arild
    Since I upgraded to Saucy Salamander 13.10, with every third suspend or so, the network is disabled and I'm unable to re-enable it. I've had to reboot to make it run again. The network menu will have the option Enable network but clicking it will only produce a tick in the menu item, nothing else changes. How can I make it enable automatically after suspend? In the meantime, is there a workaround to at least manually re-enable it? The PC is a Lenovo IdeaPad S205 using drivers r8169 and rt2800pci.

  • Lubuntu 13.10 - Laptop Loses wireless after sleep

    - by user206217
    I'm running Lubunu 13.10 on an hp G62 - I'm new to Lubuntu having used ubuntu previously, but I've made the switch as my laptop is now getting toward the lower end of acceptability, and I'm delighted with how well it runs. Anyway, I'm having an issue that if I close the lid of the laptop it won't reconnect to the wi-fi when I open it again, and I'm not sure how to even force it to scan for a network - I have to restart it at the moment - and then it always connects perfectly. The router is a BT Business Hub 405. Any help much appreciated - thank you.

  • How to deploy a single website to multiple physical servers.?

    - by user70122
    I want to deploy my PHP and Ajax based Dating website to multiple physical servers. Does anyone know the method. Is there possible any method to save the files and setting (and also the user input), on all of the physical server, so that the servers do the following jobs. Servers used as a network, speeding up the process giving a robust thing to the end user. Data to be stored on all the servers' hard drivers, and Every server have the internet connection from different provider, so for example a. if any of the internet providers gets down, or b. there occur any hardware or power failure, the website still runs, without a break and without any data loss. Does anyone know about some online course, or some comprehensive tutorials about this topic ?

  • How to mount a network drive?

    - by Relik
    Ok so I'm trying to set-up a home file server. I'm thinking about just setting it up as an FTP server, no particular reason other than I'm familiar with FTP and samba tends to be very frustrating. Basically the set-up I'm going for, is to be-able to create multiple user accounts for the server and restrict or allow access to specific folders on each user. FTP is the only way (that I know of) to accomplish a set-up like that. My question is how can I mount an FTP server as a drive in Ubuntu so that all my applications can access it just like any other driver or folder. An example would be downloading 12.10 via torrent when it comes out, I would like to be able to tell transmission to just download the file straight to my ftp server. I know how to do this in Windows, its actually very easy. But I cant figure it out in Ubuntu. I have tried using the "connect to server" option in nautilus, and it works, but it doesn’t give me the result I want, most applications don’t see the folder, while others can. Also I am open to options other than FTP if anyone has any suggestions. I've looked into FreeNAS but that doesn’t seem to allow me to control the user accounts the way I want to. Then after all is said and done I would still need a way to mount the shares as a drive in Ubuntu. The ability to mount network drives in windows is one of my favourite features, but seeing how Ubuntu is now my daily OS and has been for about 4 years, I really need a way to accomplish the same thing in Ubuntu. Also a GUI would be preferable, seeing as there will be multiple people using this server, I would like it to be as easy as possible. EDIT: this link here seems to be almost exactly what I'm wanting to do, if I could find a GUI that can do this ill be almost set. then I would just need to find a way to hide specific folders from certain users.

  • Strange traffic on fresh Ubuntu Server install

    - by Fishy
    I've just installed Ubuntu Server on my home box after becoming partially familiar with it at work and wanting to train up as a Pen Tester. I installed the latest version on a logical partition (the main one contained Win7), and selected none of the extra modules (I think). I installed ngrep and fired it up (along with TCPdump) and immediately saw some strange traffic which I am unable to identify. My pc is sending out UDP packets every couple of seconds to a seemingly random series of IP addresses, all on the same port (47669 - though I did also see it use another port for a while). I watched it do this for about 20 mins, whilst trying to work out why it was doing it. The only other traffic was the odd ARP request for the router and SSDP UPnP broadcasts from the router. Anyone know what this is, or have any advice on how best to find out? Thanks. EDIT: Actually, it's not my box generating the traffic. It's receiving the traffic on that port, from a series of IP addresses, and returning 'port unreachable' messages.

I have an Acer Aspire One D270 notebook that came originally with Windows 7 starter installed. I have removed that and installed Ubuntu 12.04 I have chronic issues with connecting to the wi-fi.

  • ubuntu will not connect after restart

    - by nicedoggy
    Firstly, I hope this hasn't been covered elsewhere, I have searched but haven't found this particular problem. I updated to 12.04 a while back and though I now thoroughly regret that decision, I'm able to live with 12.04 and all it's odd little quirks. The one problem that I would like to fix is this. I have a small network, using a router modem which stays on most of the time. If the computer is switched off, when it is switched on again I have to click on "auto Ethernet" in "Network" in order to get on the internet. It then works fine. Previous versions just connected automatically on restart. When 12.04 says it is unable to connect, other computers on the network are able to connect. Thanks for any help.

  • What are different ways to reduce latency between a server and a web application? [closed]

    - by jjoensuu
    this is a question about a web application that provides SOAP web services. For the sake of this question, this web app is hosted on a server SERVER B which is located in California. We have an automated, scheduled, process running on a server SERVER A, located in New York. This scheduled process is supposed to send SOAP messages to SERVER B every so often, but this process typically dies soon after starting. We have now been told by the vendor that reason why the process dies is because of the latency between SERVER A and SERVER B. The data traffic is routed through many diffent public networks. There is no dedicated line between SERVER A and SERVER B. As a result I have been asked to look into ways to reduce the latency between SERVER A and SERVER B. So I wanted to ask, what are the different ways to reduce latency in a situation like this? For example, would it help to switch from HTTPS to some other secure protocol? (the thought here is that perhaps some other alternative would require fewer handshakes than HTTPS). Or would a VPN help? If a VPN would reduce the latency, how would it do that? NOTE: I am not looking for an explicit answer that would work in my specific situation. I am more like looking just for a simple list of what technologies could be used for this. I will still have to evaluate the technologies and discuss them internally with others, so the list would just be a starting point. Here I am assuming that there exists very few ways to reduce latency between two servers that communicate across public networks using HTTPS. Feel free to correct me if this assumption is wrong and please ask if there is a need for specific information. NOTE 2: A list of technologies is a specific answer to the question I stated in the title. NOTE 3: Its rather dumb to close this question when it is after all about me looking for information and furthermore this information can clearly be useful for others. Anyway luckily there are other sites where I can ask around. StackExchange seems to attached to their own philosophical principles. Many thanks

  • Transfer a ssh session between the same physical devices from one network to another

    - by Vivek V K
    My server has 2 IP addresses via two networks. Due to some restrictions,my client will be able to access only one of the network at a time. Hence, I want a way to transfer a live ssh session with all the open applications seamlessly from one network to another. The physical devices (client and the server) are the same. What changes is the network through which it connects. can this be done? Thanks!
