Ubuntu Networking :: File Server Between 2 Networks?
May 31, 2011
(Fairly new Ubuntu user)I have a Desktop with 2 network cards and a file share.I currently have eth0 configured and working on a network hosing about 30 people.Now I have another 50-60 people connected on a separate network that want to be tied into the same file share. I have configured both eth0 and eth1 for the networks that they are connected on. currently only eth0 works.When I configured eth1 for some reason It shows that it was last used "never".Is there a way to keep these networks separate and share these files from this server?
eth0 Link encap:Ethernet HWaddr 00:1c:c0:fb:b4:20
inet addr:192.168.0.2 Bcast:192.168.0.255 Mask:255.255.255.0
inet6 addr: fe80::21c:c0ff:fefb:b420/64 Scope:Link

I am trying to configure my android phone (rooted Eris running kaossfroyo 2.2) to be used as a midi controller. Which I am having enough trouble with as it is but it has raised an annoying issue that occurred a month ago when I used the phones tethering network with my laptop. After connecting the laptop to the phones network (either tether, or an Ad-hoc network created using the network manager) I am unable to switch to other networks. In other words when I'm done with the phone-laptop connection I cannot connect my laptop to my home network! When I click on the other network connection I can see that it is attempting to connect in the upper right corner of the desktop (the network icon) but it will not make the connection.
What happens is that the network indicator will make the little circle graphic as if it is trying to connect but it never will display the other circle as green indicating that it has connected. but when I disconnect from the home network that is not connecting I will get a message underneath that will say that ad-hoc network disconnected! If I am switching from the android tether it will say Android-Tether disconnected etc. Even though when I click on network manager it shows that I am attempting to connect to the home network (labeled LIBERTY in my case) upon disconnection it shows the ad-hoc or tether connection being disconnected.
I am absolutely baffled by this! The issue persists even after deleting the ad-hoc connection from the wireless settings tab!!! I would speculate that for some reason the laptop is attempting to connect to the previous ad-hoc connection despite me wanting it to connect to LIBERTY. I am very confused and hope someone can lead me in the right direction.

I do IT work for a decently-sized bookstore. Over the past year or so we have had a recurring problem crop up where file transfers with networks outside of our building will be interrupted, or those receiving our uploads will get truncated files. It is an intermittent problem and I have not been able to narrow it down to any particular day of the month or time of day. Files that are dealt with in our web browsers have no issues - I can happily download and upload large files all day without interruption. Yet when our little postage meter machine tries to connect to its update server, it sometimes has its connection interrupted downloading its update files. Our credit card machines sometimes have trouble holding a connection long enough to batch out, and our storewide POS system often has to resend its credit batch multiple times before it can maintain connection long enough to push the whole file through. One server daily ftp's a ~11mb file to an associate, and a few days a month they will receive a truncated file that appears to have been cut off mid-transfer. Our bandwidth is handled through three T1 lines that share phone line and internet service. Our voice calls never get dropped and have good line quality, but mobile credit card terminals will have trouble maintaining a connection when they dial out.
I'm thinking this is either an ISP issue or an internal network problem. I don't know what protocol the mobile machines use, but it's possible it could be restricted to ftp or, I dunno, telnet? Maybe a port forwarding conflict? Files sent internally have no problems, so I'm thinking it's something at the firewall/proxy/router stage.
Our servers run a number of *nixes: our central databasing/pos is handled by an IBM RISC box running AIX 4.3; our DHCP server runs Debian Sarge 3.1; we have a Ubuntu 8.04 LTS box running a squidproxy setup using squidguard for url filtering; firewalling is handled by a Debian 5 box running Untangle. Our ISP provides us a 4.5 Mb connection via three T1 lines that provide shared bandwidth for our digital telephone lines and internet.

I have setup an ubuntu gateway server by using four NIC cards.
eth0 :210.212.235.107 is connected to the internet
eth1 :192.168.1.222 is connected to the local network
eth2 :192.168.2.222 is connected to another network
Here 192.168.1.222 is the gateway for 192.168.1.0 network and 192.168.2.222 is the gateway for 192.168.2.0 network.These network configurations are working fine, but i want to block inter network communication ie from 192.168.1.0 network to 192.168.2.0 network,i want to block the communication for securing the local networks more.I know iptable rule is enough for this purpose .But i cant find the apt rule for this purpose.

A server is acting as a router between two networks. If the load increases what happens, to the speed of network? whether the network speed will be reduced or it will sustain the same speed (Ex: 100MBps).

I could use Wireless network. I could see several different networks in my range. Then suddenly the network stoppedworking, and I can no longer see any networks under "Wireless networks".The Wired networks works fine.I tried upgrading ubuntu, but nothing changed. Just to confirm, I rebooted the computer in Windows Vista (Dual boot) andconfirmed that Wireless worked fine there. No hardware problem then.The suggestions I have found on this and other forums suggest looking at the output from iwconfig and ifconfig. But since I'm a n00b at Ubuntu I don't know what to make of it.
This is the output:
emil@emils:~$ iwconfig
lo no wireless extensions.

I installed Ubuntu 11.04 Desktop and can access the internet through a linksys router with WPA2. I then installed Ubuntu server in the free space left on the disk, but the installation network autoconfiguration failed. I can boot either OS, but the server's DHCP client cannot discover any networks (there are several in the area).

i have a working squid ncsa authentication. i have this in my squid.conf
Code:
acl password proxy_auth REQUIRED
acl employees src 192.168.0.2
acl admin src 192.168.1.2
[code]....
this setup makes squid authenticate both the employees and admin network. how can i make squid just authenticate only the employees network? admin network should connect to squid without authentication.

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 just bought a new toshiba c655 laptop and had windows 7 on it. i made the dual boot partition on it, yada yada yada, anyway, on the windows partition i can see two networks at my house. one is mine, one is my neighbors. but when i go to the ubuntu side of things not a single wifi network shows up. i did a little combing of the forums and decided to try installing the ndisgtk package which i obviously need internet for. i thought i would plug it into an ethernet cable running straight from the modom and i could connect and download no problem. however. this has turned out to be quite a mistake. ubuntu does not even recognize the fact i have an ethernet cable plugged in. this may or may not be related, but niether my ipod or my cell phone does not show up when i plug those in and when i try to mount them i get an error message that says they could not be found. Im running 10.04.

I have an hp dm1z and ubuntu 10.10 64bit. After I suspend (close the lid) and wake it up (open the lid) at a different location with a network connection (wired or wireless), my system always fails to connect. I need to reboot and then it sees the network and connects fine. I have tried /etc/inet.d/networking restart, but nothing changes. The only exception to this rule are two networks that have WPA security settings and are stored. I can always switch between those two. I have tried ifconfig eth0 up & down and restart networking. I have also tried to connect manually (dhclient) and no success. None of these work. I am including the output of lshw -C network.
lshw -C network:
*-network

I have an MSI Wind U100 netbook running Maverick, and it has a Realtek RTL8187SE Wireless controller according to lshw. My computer can "see" some wireless networks where they are present, meaning when I click on the little network icon at the top of my screen it shows the available networks. But when I click on them to connect, the icon does its little "connecting" motion, but I never receive any message saying "Connected" and when I open Firefox and try to browse to google.com, it says "Server not found"

I have an ethernet card connected to my LAN and a USB cell modem internet connection. I am running ubuntu 10.10. The problem is this: I can use either network, but only am connected to one of them. If I connect to both at the same time my speed drops to zero.f I disconnect one, the other starts working. I have done a lot of searching and reading, but it looks like I don't know how to find what I am looking for.My LAN was setup as 3 WinXP computers peer to peer. One of those computers was replaced by this one that I am having trouble with (computer A). Another one was replaced by one that is not yet on the network (computer C).Computer B dual boots Win XP and ubuntu 10.4. Mostly it ns xp for Quickbooks and BobCAD, also it is connected to the printer. My router is setup for DHCP

I set up a ubuntu server 10.04 lts as file server in a network filled with xp, win 2003 and win 2008.
I noticed that if from any bill's SO machine i copy a file (for example a vob file of 1gb, or a lot of doc and pdf files) in the samba server, while the copy is in progress if in another windows I browse other folders shared in Samba, the copy process stops and say ' the name in the network is no more available( or something like this). It seems that samba pay attention on the fact that a user is browsing the share and doing so it seems that Samba forget that in one of its share there was a copy in progress, very annoing. A file server cannot do that, in this way is useless.

I have been having trouble getting my network card to access networks. I currently am using a wired connection. A while ago when I first installed Linux on this same computer, I got it working by installing the driver. But since I reinstalled Linux, I tried the process again with no success. Can anyone give me explicit instructions on installing the network card driver so I can use it on Linux.

I'm dual-booting Ubuntu 9.10 (upgraded from 9.04) and Windows 7 on my Dell Inspiron 1525 laptop.Ubuntu doesn't recognize any wireless network (both in 9.04 and 9.10); my Windows OS works perfectly well with wireless, as does my wired Internet connection with Ubuntu and Windows.I've had this problem on previous installations of Ubuntu (I've removed and re-installed it several times) but I can't locate the solution anywhere. I've tried numerous fixes that I've found online, but none of them have worked.System>Administration>Hardware Drivers tells me that the Broadcom STA Wireless driver is activated and currently in use

I can normally connect to most wifi connections, but for some reason I can't connect to my broth's-gf-parent's network. Windows 7 can connect to it just fine, but not Ubuntu. Once in a while I'll go to a cafe, and this will happen there too.hough, like I said I can normally connect to all other wifi networks with no hassle

I'm running Ubuntu 10.04 64bit on a Thinkpad T61, and I keep running into some issues with the wireless networks. For a while, the connection works fine (sometimes several hours, sometimes 15 minutes or so--there doesn't appear to be an event associated with it). Eventually, though, the connection disappears; first, though the widgets say I'm connected, nothing will go through, and soon after, it realizes I'm not connected and, moreover, it can't find a single wireless network, despite the fact that it was just fine a couple of minutes beforehand (and other devices still have access to the WLAN, so I know that the router hasn't crapped out). I've tried using wicd, but the same thing happens.

I am quite new to Ubuntu, so please give me easy to follow steps.So, I have just installed Ubuntu 10.10 x64, but cant get my wireless to work. It detects my networks and tries to connect to them - infinitely, whithout success.I have tried it on an unprotected and on a WPA2-personal protected network with the same results.My card is a RaLink rt3090.

I have a pretty beat-up laptop, on which the inbuilt wireless doesn't work, and so I now have an ASUS WL-167g, which is acting up!It almost always connects to the required networks without an issue, but then once I'm connected it's REALLY slow on some of them! For example, while I'm at school, it works flawlessly! And at a couple of friends' houses, it works too! however, at home, and at a couple of other places, despite the fact that it connects, its so slow, that google takes like 5 mins to load and searching for anything on google leads it to time out!! This happens whether I'm right next to the router (full signal strength) or 2 floors up (at like 3 bars strength)!
It's getting pretty frustrating to have to swap my lan cable between my desktop and laptop constantly, and also to not be able to use my laptop away from my desk!Does anyone know what might be going on??Also, while i have you guys here! I have another problem -- with the inbuilt card.. Initially, it wouldn't work at all.. but more recently, it has started to function (it connects and works on my home network fine) the only problem is that about 10 mins after I turn the wireless switch on on my laptop, it hangs! (EVERYTIME) (if it's relevant, my laptop is a SONY VAIO VGN-S46GP). Again, any input would be appreciated!!

I installed Lubuntu yesterday on an older Dell laptop and the installation went fine. The only thing not working after the installation was the wireless. After hours of searching, I was finally about to get it to recognize the wireless card, see wireless networks, and connect successfully by running these commands.code...

I have ubuntu 10.10, and at my house I primarily used wired, and it works fine, and under windows earlier today I was able to locate networks, so my wireless card is working. I'm currently at my girlfriends house, and trying to connect to her wireless internet. When I try to connect, I can't find any networks. I've made sure her network has sharing and discovery enabled, however in my wirelss manager it comes up as blank. There's the option to add wireless manually, but do I really need to go through the trouble of finding the routers mac address and all that, it should just show up?I could switch back to windows to see if I can connect, but I'm almost positive it's just the linux wireless manager..

I arrived in the Central African Republic only to find that my wireless (on an HP Mini 5102) wasn't working -- it didn't detect any wireless networks. So I wiped off Windows and installed Ubuntu 10.10, Luckily, it did! (Partly.) At first, I still didn't get any wireless networks. I messed around with all the various things you have to do to get Broadcom wireless drivers working. Finally, following a forum suggestion, I installed Wicd -- and this did the trick. Not knowing any better, I kept Network Manager alongside Wicd, but Wicd is what works much better. (Is there a reason to un-install Network Manager?)
However, when I try to connect wirelessly to the network at this country's one cafe with wifi (which usually works really well, by CAR standards), the network doesn't appear. At the office, when I open Wicd, it includes a box with the message "<connection name>: obtaining IP address", and bit by bit it connects. But when I open Wicd at the cafe, this doesn't happen -- it just gives me a list of random signals from nearby offices (all secured and low-signal), none of which I can connect to. Any ideas how I could get the cafe network to show up?I'm at the office now, and so it's working. However, in order to get it working I had to restart three times -- Wicd only seems to work about half or 33% of the time. Sometimes I get the message: "Connection failed: unable to get IP address" and sometimes I get the message "No wireless networks detected." Then I try again and eventually it works. So far.
