Networking :: Multiple Network Connections - Internal And Wireless

Dec 4, 2008

What I want is quite simple, I have my PC running Linux Mint 5 (Elyssa), and I would like to connect it to both an internal network, which has a file/print server, another machine and will soon host a small cluster. I also have a wireless router connected to the tinterweb.

The thing is using my ethernet I want to connect to the internal network whilst simultaneously using my wireless to deal with the internet, I want to keep the internal network off the net as it really doesn't need to be connected. I can connect to my internal quite happily and also my wireless but not both at once.

Fedora Networking :: DNS Not Working With Multiple Network Connections

Mar 5, 2010

I have a machine that I'm trying to setup as a reverse web proxy. It will have two NICs, eth0 will face the public network, and eth1 will face the "internal" network (connects to a switch that goes out to the other web servers that are statically assigned a private IP address).

When both interfaces are started, I can ping hosts on the 1.2.3.0 network and the 192.168.10.0 network without problem when doing so by IP, but if I try to run a ping or nslookup command with a DNS name, it does not work. I've tried commenting out my entries in /etc/resolv.conf and adding the DNS entries in the /etc/sysconfig/network-scripts/ifcfg-ethX files directly (DNS1=x.x.x.x and DNS2=x.x.x.x), but the results are the same.

Ubuntu Networking :: Multiple Network Connections On Different Networks?

Sep 20, 2010

I am total newby in Ubuntu 10.04. I have just installed it in my office where I have two networks card one connect to a router giving the internet access and the other connected to the windows based work network providing access to the work network sources. In XP everything works fine as I can keep both connections alive and have the results I want.

However although I don't know how to do it in Ubuntu 10.04. Till now I have setup the first connection directly to my router and I have internet access but I cannot set the other one. Another question is how I can force ubuntu to use the router connection as the default one when I log in.

Ubuntu Networking :: Staying Connected To Wireless Network With Multiple Access Points

Oct 15, 2010

I can connect to my school's wireless network using the standard network manager, but often (not always) it repeatedly disconnects and reconnects every few minutes. Occasionally it also prompts me for the security information again (even after it previously connected successfully).

By running iwconfig when it's on the fritz, I can see that it's often switching access points for the network - which is what I think is causing the problem. It disconnects and reconnects even when the signal strength for the current AP is fine, and it will often switch to an AP with a weaker signal strength.

$sudo lshw -C network
Code:

Networking :: Multiple Mobile Broadband Connections

Jun 28, 2010

I have a question concerning mobile broadband connections: Is it possible to have multiple mobile broadband connections active at the same time?I currently have two cellphones connected to my Ubuntu box and both of them can successfully setup an Internet connection for my Ubuntu box (say connection X or connection Y), though not at the same time. Unfortunately both connections are very limited in speed (around 10kb/s each. And this is my only access to the Internet where I live). Therefore, I wish to use the two connections simultaneously to download files from the Internet (file 1 with connection X and file 2 with connection Y). Is this method of doubling my bandwidth possible in Ubuntu?

Fedora Networking :: Multiple ADSL Connections To A Fedora10 Box.

May 18, 2009

I got 2 ADSL accounts from a provider, so I decided to configure a server as a gateway for my other PCs.. I created ppp0 device using pppoe-setup over eth0. Then I configured the second one as ppp1 over eth2 to the second modem.. When I finished, I used ifconfig to check the settings and I got only ppp0 and didn't see ppp1, I tried to ifup ppp1 but I still get one device with ifconfig.. The adsl-start command starts only ppp0.What should I do to get the 2 lines to work simultaneously?Are there any configuration files that need to be edited?

Ubuntu Networking :: SFTP Multiple Simultaneous Connections

Feb 7, 2010

I really hope someone could help me with this problem. I've been stuck on this for a month.I am using the sftp command to upload files using a bash script.The problem is that it is extremely slow to do it this way. as many of you would know if you have shared server somewhere. I would use scp if remote server supported it, but it doesn't.

Anyway, If any of you have ever used FileZilla, in the Settings, if you go to "Transfers" there is a place where you can set the number of "maximum simultaneous transfers". This feature works wonders with SFTP (and FTP too). It really speeds things up. How do I accomplish this same thing with the sftp command... because I don't want to use a GUI. I don't even mind using FileZilla through the command line if possible... but it does not seem to be possible. I've been stuck on this for a month!!! I've searched everywhere and tried a lot of things with no avail...

Networking :: Routing Torrents With Multiple Connections / Adapters

Jul 8, 2010

Running Fedora 13 and have it working great acting as my firewall/router/samba server etc. The problem is the connection is shared by a fair number of us and the ISP is getting annoyed with the amount of torrent traffic. One of us has access to a wireless network and we'd like to figure out how to route some of the traffic through that without having to disconnect from the current network. I put a wireless card in the fedora box and can connect to the wireless but then it messes up the current network and pretty much nothing works.

At the least if I could run a torrent client (e.g. ktorrent or whatever) on the Linux box and have it download through the wireless card on tcp port XXXXX I would be happy. The torrent client and those tcp/udp ports can be dedicated to that wireless card, the rest of the network doesn't need to get involved if that makes things simpler. Not looking for a step by step tutorial, just an explanation of what needs to be done and a shove in the right direction. My experience is limited to single WAN connections up to this point.

Ubuntu Networking :: Manage Multiple Internet Connections With Different Cards?

May 25, 2010

I'm running ubuntu lucid and i was thinking in purchasing one or more extra wifi cards to try to configure my computer to manage different conections at the same time, with different isp's. The thing is that I'm not quite sure if what i want to do is actually possible.

The easiest way that crossed my mind was to try to configure a / multiple virtual machines that are redirected threw proxies to ubuntu and try to configure that each proxie port goes threw a different internet gateaway. This way i might be able to divide threw different sessions of JDownloader, installed on each virtual machine, the things i want to download. The negative aspect of this idea is having multiple jdownloader sessions will make my laptop work to almost 100% for sure...

Another thought i have was to make JDownloader manage its downloads in only one session redirecting them to my internet conections; the negative thing is that i think i will have to try to modify its source and learn java...

And well my last possible configuration i had in mind was to try to make ubuntu directly add up all my internet conections manage as if it was one. the negative thing here is that i might not be able to get multiple downloads from some sites

Well, all this where just thoughts, im struggling whether to buy another card or not to try to setup any of this configurations but im not really sure if any of them are actually possible. Is there an easy way to manage this?

I just want to take the most out of my internet conections... if i'm at college i have to options that are quite slow, adding them up with two cards would be great, i might also be able to add a third and a fourth conection. Also if i'm on a coffe and i need some bandwith i could try to make it go with an open network arround, etc.

OpenSUSE Wireless :: Network Manager Crash During Edit Connections?

Mar 24, 2010

Every single time I enter the network manager to edit connections is crashes on exit. I am running opensuse on an Asus eee PC 1000HE with an Atheros network card. The crash report follows :

Distribution: openSUSE 11.2 (i586)
Gnome Release: 2.28.2 (null) (SUSE)
BugBuddy Version: 2.28.0
System: Linux 2.6.31.12-0.2-default #1 SMP 2010-03-16 21:25:39 +0100 i686

[code]....

As an extra point. I wish I could disconnect individual networks instead of just disabling networking to disconnect. I think the newer version of the network manager does this.

Slackware :: Wireless Connections - Valid Ip Address, But No Network Connectivity?

Apr 8, 2011

I'm having making network/internet connection with my laptop. I have:Toshiba 1415 S173laptop
NetGear WG511T pcmcia card using madwifiNetGear WPNT511 pcmcia card using windows driver via ndiswrapperSlackware 12.2In both cases the card is recognized, and I can get a list of access points with iwlist.I can set the card to connect to the desired access point. I can use dhclient to get an ip address from the remote dhcp server. This works, the card is assigned a valid ip address on the desired network.Once I do this, however, I cannot access any network resources, no Internet, and no other devices on the network can see, ping, or access my laptop. It does this with with both cards, using madwifi or the windows driver via ndiswrapper.

Networking :: Creating Simultaneous Network Connections To A VPN And Local Area Network?

May 31, 2010

I'm working with a Ubuntu 10.04 LTS system with two network interfaces (both Ethernet). I wish to setup this system such that it is simultaneously connected to my local and an OpenVPN network and able direct traffic between the connections depending on what program is sending the traffic. The problem: Under my current OpenVPN configuration all network traffic is directed to the VPN.

My OpenVPN config file (some details omitted)

--remote [gateway ip] # vpn12 load:
--remote [gateway ip] # vpn11 load:
--remote [gateway ip] # vpn15 load:
--remote [gateway ip] # vpn16 load:

[code]....

In practice, I would like OpenVPN to operate out of one of my two network interfaces and leave the other interface connected to the local network. Then by default all network traffic should be directed to my local network unless I specify (on a per program bases) that certain traffic should go though the VPN. These two network connections can (should) stay completely independent of each other and do not need to talk to each other.

Networking :: Internal Wireless As Outside Interface ?

Dec 3, 2010

What i wanted to do was use a linux machine with a wireless and wired interface to act as a router. The wireless interface would be the outside and get its IP via DHCP from the wireless my landlord provides. The wired connection would be for my local pcs. I understand it would be slow having multiple pcs using a single wireless gateway.

Networking :: SSH From Internal Network

Oct 6, 2009

I am not too knowledgeable on networks, however I think this should be possible.I have a computer at work, which is connected to the work network. I have files stored on the central server here and also my local computer.

At this place, computer support say "We do not offer this service". However they also say "The simplest way to do what you are asking is to install an ssh server on your actual workstation".I have done this, and it the openssh server is working because I can test from my workstation by doing ssh user@hostname and it works.What I want to do however, is to connect from outside the network. Firstly, is this possible, and secondly, what is the syntax for ssh in order to do it.

Ubuntu Networking :: Wireless Connections Not Found

Nov 10, 2010

I have an Acer AspireOne D255 netbook. I just installed Ubuntu Netbook Remix 10.10 and it looks pretty sweet.Right now, I'm on a wired connection. It's not detecting any networks, and I know at least my home wifi should show up (and usually we can get onto our neighbors!)I used to have a different model of an AspireOne (I think it was 531h but I'm not 100% sure) with UNR 10.04, and my network was detected right out of the box.

This reminds me of when I installed the desktop version of 10.04 on my iMac. I couldn't bring the wired connection to the room it was in, and my wifi didn't show up on it. I just gave up because I like my Mac so it wasn't a *huge* deal. but I definitely don't want to use this stupid Windows 7 Starter that comes on this netbook!

Ubuntu Networking :: Wireless N Dropped Connections

Jul 4, 2011

I'm working right now with ubuntu 11.04 on my asus ul30vt-x1, my wireless n network is working on a linksys e3000 router, my issue is basically with long file transfers. When the issue started i was reaching speeds of 100 Mbps through my wireless network even when I'm connected at 150 Mbps. However when at this speed, I don't know why, the connection is dropped after some minutes or even seconds. I made some testing on windows, I'm reaching 70 Mbps there and no problem at all with dropping the connection.

So my conclusion is that for some reason the linux driver, in my case, is not able to handle such speed of 100 Mbps. I know that a wireless network will have a throughput of aprox 60% the wireless speed. Right now im trying to apply traffic shapping to my transfers so i can get 70 to 80 Mbps, its being working so far.

Ubuntu Networking :: Networking Connections Not Listed In Network Manager

Aug 23, 2010

Neither of my wired network connections are listed in the network manager applet. I know that networking seems to be functional since I can ping local devices on the network. I can't resolve DNS names however. I suppose this is because network manager usually handles DNS? I've posted the outputs of various configurations below.

Code:

/etc/NetworkManager/nm-system-settings.cfg
# This file is installed into /etc/NetworkManager, and is loaded by
# NetworkManager by default. To override, specify: '--config file'
# during NM startup. This can be done by appending to DAEMON_OPTS in

Is there a way to log specific type of network connection with timestamp? I mean, if someone sends a mail through mail server, is there a way the server logs that connection with timestamp?

Example:

2010-03-17 14:10:26 <server>:25 <client2>:<port2>

Networking :: Unable To Run 2 Network Connections

Oct 29, 2010

I'm having trouble running 2 network connections on an Ubuntu 10.10 machine. My wireless connection provides my internet access and is assigned the ip 192.168.1.7 My ethernet connection provides access to a separate network containing a nas box/server. The ip address for this is 192.168.5.100 When I am only connected to the wireless network, the internet works fine. However, once I connect to the ethernet network, I lose internet access via browsers and email client I cannot ping external web servers. It doesn't appear to be an ip address conflict so I'm at a loss as to what is causing my internet connection to drop.

Ubuntu Networking :: Cannot Use Internal Wireless Device

Jul 10, 2011

It's been ages since I've been on here I've been messing around with BackTrack. I've come back to Ubuntu but seem to be having some problems getting my wireless network thingy working. Here are the specs of my system. Any advice on fixing this would be very very apprciated.

02:06.0 CardBus bridge: ENE Technology Inc CB1410 Cardbus Controller (rev 01)
02:08.0 Ethernet controller: Intel Corporation 82562ET/EZ/GT/GZ - PRO/100 VE (LOM) Ethernet Controller Mobile (rev 01)
10:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)

On another note I'm trying to run debain I've got no startx on there or anything like that it's feeling very basic atm. I want to keep startx outta there but I can't connect to the Internet and run apt-get install to grab handy things.

I'm hoping whatever I am gonna do to solve this on Ubuntu will let me connect up to my wireless network with the internal network thingy. However if it doesn't I'm guessin I can just connect up physically to the router. Any tips on doing this from the command line?

cannot ping internal network

I am a new user to Linux but in the last couple of months gained some Idea about it,I am trying to set up a small network in my office having 3 windows xp PCs, two fedora10 PCsI have an adsl router with 4-port hub connecting to the internet, one switch (say sw1) and one linux PC (say linux1) is connected directly to the router, the three win xp PCs are connected to switch sw1.all the above is working fine, I am able to get connected to Internet In all the systems, and able to network among all the above four.Now I want to make the linux1 as a proxy server for, hence I added another network card into it connected it to another switch sw2, which is connected to another linux pc (say linux2).

I have tried a hundred things, and googled an equal no. and finally posting it here.In order to reduce confusion I have disabled DHCP in all machines, and given static ips insteadNetworkManager was not happy about it, hence to fix my static IP i disabled NetworkManager ('chkconfig NetworkManager off')
