Networking :: No "connections" Tab In Network-settings In UbuntuStudio 10.4?
Aug 2, 2010
Just installed UbuntuStudio 10.4 X64 next to my main Ubuntu 10.4 X86. For some reason the network-settings app is not working right.I use a Netgear WG311v3 wifi card to connect to my home network and I'm a pro with using ndiswrapper to emulate the drivers for both 64 and 32 bit machines. Everything driver-wise works and iwconfig shows my card as installed and working.When I want to connect to the network I go to System > Admin > Networking to set everything up. But the problem is, there is no "Connections" tab. Only "General", "DNS" and "Hosts". So I cannot select my wifi card to set up the ip's and everything. I haven't tried using a normal UTP cable, as it's quite a hassle to extend it to my room, but I'm sure I will get the same results.How come everything works hunky-dory in Ubuntu, but not in Studio? It's exactly the same!
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.
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.
I recently installed Fedora 15 now, and during installation I set the internet connection manually, then did update and after reboot, the internet connection settings have been removed. Now I can not set because the network connection to the Internet Connection is inactive. I mention that before the update was functional internet connection.
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
once I updated , there will be no connections to Internet in GUI , while it's available in TUI . So it's wired , huh ? Before upating, it's available both in TUI and GUI, though all the time the network-manager shows no connection , in fact , there is and both GUI and CUI . Now I updated , and it can't access Internet from GUI.
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?
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.
Here is the layout of my network:My cable modem plugs into eth0 on my ubuntu server which acts as a firewall (shorewall) and dhcp server to my lan. A dd-wrt access point is plugged into eth1 and then a bridge connecting my xbox360 and another bridge connecting a desktop computer.Everything works pretty well, except a few times a day, my network will just shut down. The wireless on my macbook and my wife's laptop will just shut down, and if my xbox is running, it will lose connectivity. It will be down for maybe a minute or two, and then come back up like nothing ever happened.I never had this problem when I had just a dd-wrt router running everything instead of my server.When I ssh into my server afterwards and run dmesg, this is what I will get:
Code: [398598.251548] martian source 169.254.1.255 from 169.254.1.33, on dev eth1 [398598.251565] ll header: ff:ff:ff:ff:ff:ff:00:23:69:3d:b1:82:08:00
i've installed ubuntu 11.04 on a friends Asus Eee pc 1005HA netbook. after the installation i tried to connect to the router using wireless, and when i enter the key, it fails to connect, so i tried using an Ethernet cable to connect but that doesn't work either,the network devices on the computer are:
Atheros AR8132 PCI-e fast ethernet controller Atheros AR 9285 wireless network adapter
It lists the wireless device and the solutions to the problem, however, the solutions seem to be for Ubuntu 10.04 and also 10.10, and im not sure if it will work for 11.04 so far i have been unable to find out anything on the forums about the ethernet
[bee@localhost ~]$ ulimit -a | grep files open files (-n) 1024
that open files value set to 1024, but is it valid only for real files ("file handles/descriptors" of files on your filesystems: hd partitions / cdrom / floppy / usb devices) or does it counts also network/sockets connections? i'm just asking without a reason. it's just curiosity ... as you can see sockets with lsof, somebody like me could think connections are counted as they were "files" by ulimit too
I want to write a custom rule to allow all connections to the ip addresses on my local network (192.168.2.2 through ...99) but I don't know how. I know adding a custom rule asks me to read a file and put it in "iptables" format, but I don't know how...
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.
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.
Since I installed ubuntu 10.04 I dont see my eth0 card in System->Preferences->Network _connections. Everything works fine but it puzzles me. In ifconfig iI just see the eth0, networking seems to be working fine, but it keeps puzzling me. Adding theinterface is no solution: add it and it doesnt show again
Using xubuntu 11.04, how do I maually give myself a static IP address and other IPv4 settings? I see the edit connections panel and saved a setting there but can't see how to use that setting. The only useable setting when I'm connected by ethernet is Auto eth0.
i'm currently using ubuntu 10.04 and wanted to update to 11.04 and that means backing up all sorts of data and configuration.Regarding the wireless configuration list, i have a few with password and auto connect, i wanted to know if there is a way of saving that listconfiguration other then manually.
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.
I have just installed Ubuntu 10.10 64bit on my laptop Toshiba Satellite A665-S6065 and I can connect to wired network but I can not connect to wireless network "Network Connections disconnected". Im following this post http://ubuntuforums.org/showthread.php?p=6183681

I am running Ubuntu 9.04 as a partition with windows 7 on a acer aspire 5742, I would like to connect to the internet in Ubuntu, wirelessly, but I am unable to turn my wireless on in Ubuntu, and network manager says "no network connections available". I have the following network adapters:
All connections on my computer start loading and then hang: it happens when running apt-get update (a few repositories load successfully and then it hangs at a random one) and when loading web pages with the browser (it says "Connecting...", then "Waiting for....", sometimes some part of the page loads, and then it hangs).
This happens both with my wired and my wireless connection. It does not happen on Windows on the same computer.
I messed up my Network Connections when I put a different NIC in my computer. Now I just went back to using the old NIC. It shows up in ifconfig, but the GUI Network Connections is blank. When I manually Add the connection back to the GUI Network Connections, the settings are not reflected when doing ifconfig.For example, I change the IP address for eth0 in GUI Network Connections, save the settings,
I have a bunch of Ubuntu boxes on one subnet, 192.168.1.0. I have a Windows 7 box on another subnet, 192.168.2.0. I am able to ping and SSH to all servers on the .1 subnet except for one server, which I will call PITA. I will attempt to SSH to PITA, and it won't respond, nor does it respond to pings. I will the SSH to PITA from another of the test servers, successfully connect, and then when I SSH from my Windows 7 machine I can connect successfully. If I first connect via console to PITA and send some pings out (to anywhere, like 4.2.2.2), I can also connect from my Windows 7 machine. I've never seen anything like this.
One of the weird things is that I used PITA to create an image that I then used to create many of the other test servers, and they work fine, so I'm not sure what the problem is. I've checked /var/log/messages and syslog and there's nothing in them that indicates a problem. I've rebooted this server, restarted SSH, changed the IP in case it was conflicting with something else, forced an ARP update in case it was cached (since I had bonded the interfaces), cleared the ARP cache on my own machine, verified Network Manager is not installed...and I still have this issue.
Here are some network-related config:
/etc/network/interfaces

My firestarter is denying connections on ports 80 and 443, despite the fact that I have set rules to allow both the services, and indeed any connection from my gateway (the source of the connections).
Can someone please advise why this might be?I can surf the 'net fine, unfortunately I cannot load facebook, gmail, or another couple of sites that require logins, and I assume this is due to HTTPS not communicating properly.(On the off chance anyone can answer these real quick, I'm also trying to solve my resolution resetting every time I restart, and one of the icons in my KDE panel turning into a widget from an icon every time I restart. Still working on these, but just if anyone knows already).
how to resolve an ip with a port in linux?, how to include this on the dns. So the user don't have to remember the ip address and the port. like the user will only type http://scanfiles then it will resolve the corresponding ip. is it possible?
small non-profit set up an isolated network for a classroom, not connected to the Internet. Most of the computers are old second-hand systems, made usable by running Linux, the one new computer can dual boot Ubuntu and Windows. I think the most light-weight approach would be to use one of the network numbers reserved for private use, assign static IP addresses, and host names in a hosts file, rather than relying on DHCP or DNS, because this wouldn't rely on any servers. But, even so, I expect to have to configure _something_ for the IPs of a gateway and DNS servers when we set up the static IP settings.what would work best for these settings?
The best guess I can make would be to list a real system with a tcp/ip stack that wouldn't be too tightly firewalled, so that requests would get promptly rejected (or handled if there is a trivial way of doing so), rather than timed out. But, I'm looking for more specific advice of what works on practice. (I'm familiar with other flavors of Unix/Linux, and TCP/IP in general, mainly from running applications on servers, but I don't have much experience on Ubuntu.) These systems would be on Ethernet switch, but I don't think we can count on any router appliances. I suppose one of the spare computers could be dedicated as a minimal router. The objective of all this networking is to set up print sharing and perhaps file service, using one of the better computers as a server.
My first post. I lost all connections to the internet on my Linux Box Yesterday. I have checked my broadband connection and router. OK because I am using them to sent this from my laptop. I have 2 ethernet cards - no indication of a problem with either so I suspect for reasons unknown I have lost all my network settings. The Desktop User Guide says go to the Network Settings Window. I used to have a widget on the Menu Bar which enabled me to check the settings but for some reason it vanished a month or so ago and I can't find how to get it back.
PS In the meantime I am stuck with this crummy Microsoft box the interferes with everything I try to do.
is it possible to specify differnt settings for ssh depending on where somone is logging in from basically i want PasswordAuthentication yes when someone is logging in from 192.168.*.* but set to no when logging in from anywhere else
I'm running Fedora 10. My Network Manager settings are all grayed out. They are uneditable. I can see the detected settings, but not change them. All of the settings fields are disabled.
Is there a way to enable these, so that they can be edited?
Starting with the menu in the upper left corner of the GNOME screen: System/Preferences/Internet And Network/Network Connections
The Network Manager window appears correctly.
I see all automatically generated settings that were created for my various devices:
In particular, I want to be able to edit "Auto vmnet8", for VMware usage.
I know about the workaround of going back to the manual network configuration as used in older versions of Fedora, such as editing the files in /etc/sysconfig/network-scripts/ifcfg-* and then enabling the old "network" service and disabling the "NetworkManager" service.
However, this workaround really won't work in this situation. The VMware interfaces, vmnet1 and vmnet8, are virtual interfaces that *only* exist when the VMware services are running. The VMware services are started *after* the old manual network configuration would be applied. So, at the time the scripts in /etc/sysconfig/network-scripts are processed, the vmnet1 and vmnet8 devices do not yet exist! I'm hesitant to change the numbering of services, lest other things break (VMware on Fedora 10 is rather fragile already).
I love the feature of NetworkManager to be able to automatically apply settings to newly materialized network devices (such as vmnet1 and vmnet8 when VMware is loaded). However, I need to also be able to edit those settings.
Is there a solution that will make my Network Manager "Edit" window not be entirely grayed out? I can see the settings pages just fine, but unfortunately, they are all disabled and I can't edit them at all.
Does anyone havea good tutorial on Fedora's network scripts, how to edit them, in what order they are called, etc. What I want to do seems simple, but something in the bootup keeps changing it. Right now, I have an image of Fedora Core 7 created in a server with 2 Ethernet cards. I need to specify static IP addresses for each card. Thats simple, and I did that. Now, heres the tricky part, I need to be able to clone this image and place it onto other exact duplicates of the hardware, and have all of the settings stay the same.
What happens here, is that eth0 and eth1 are stored somewhere as devices, and upon boot on a different machine, the Fedora will mount new network cards(different MAC addresses) as eth1 and eth2. It then mvoes my ifcfg-eth0/1 to a backup, and creates two brand new network setting's files, which initialize to DHCP. This creates an issue, becuase these machines do not have monitors nor keyboards attached, nor is their a DHCP server, so its a pain when I swap the machine out, to have to go in with a keyboard/mouse/monitor and reconfigure the network settings before I can connect to it over the LAN.
So does anyone have any advice on how to do this? No matter what i tried, booting the image in a new PC caused Fedora to create two new devices and create brand new network settigns for them, both initialized to DHCP. Hell, I wouldn't care if it created brand new devices, if it would initialize them to static IP addresses that I am expecting.
