Ubuntu Networking :: Network Config - Edit Connections

Jun 14, 2011

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.

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.

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.

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

Ubuntu Networking :: Network Connections Keep Dropping?

Jan 30, 2010

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

Networking :: How To Log Network Connections With Timestamp

Mar 17, 2010

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 14:10:12 <server>:25 <client1>:<port1>
2010-03-17 14:10:26 <server>:25 <client2>:<port2>
2010-03-17 14:13:09 <server>:25 <client3>:<port3>
2010-03-17 14:15:43 <server>:25 <client4>:<port4>

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 :: 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.

Debian :: Cannot Edit VPN Connections As A User

Aug 24, 2015

I am trying to add an OpenVPN connection from the Network Connections GUI. The problem is everything is greyed out when I am logged on as a user. When I log in the GUI as root I can create the OpenVPN connection no problems. The problem with that is the option to use my newly created VPN connect does not appear when I log back into my user. I have tried adding my user into the sudoers file to no avail.

How can I give my user privileges to add OpenVPN connections?

Ubuntu Networking :: All Network Connections Start And Then Hang / Sort It?

Apr 4, 2010

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.

Any idea on what it might be?

Networking :: Ubuntu Server Does Not Accept Incoming Network Connections Like SSH?

Feb 25, 2011

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

Fedora Networking :: Are Network Connections Counted As They Were Files

Feb 11, 2009

Code:

[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

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.

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.

When I restart my network, my NIC card does not come back up with the correct info, and for the life of me, I can't figure out why. Here is the NIC info for eth2 when things are correct [Replaced the MAC address due to paranoia, but it's correct on my machine]:

I found that dhcp3-client was not installed and fixed that. My etc interfaces has this for eth0: Auto eth0 Iface eth0 inet dhcp What other packages or config do I need to make the internet work? It's missing something basic that wasn't setup properly. I do get the correct dns address to my isp provider when I check etc resolv.conf. It just can't dhcp discover.
