Ubuntu Networking :: SSH Over One Network Connection And Out To Internet On Another Network Connection

Jul 9, 2010

I need to setup an Ubuntu Server to handle backups over the network (probably rsync over ssh). That server will then transfer the backup data offsite over a secondary external data line.How can I configure the ethernet interfaces to handle such a scenario?

OpenSUSE Network :: Network Manager Default Connection Can Handle Virtual Interfaces?

Jun 7, 2011

I've not found how to configure more than one ip address with network manager.Nor with kde nor with plasmoid network manager.I need several virtual ip addresses for eth0 when the "default" of eth0 is connected i.e. "Connected to Auto eth0" should initialize the virtual interfaces.I have not found no even how to configure the ip address.I think this will be used from ifup config in yast or not?There I have the virtual interfaces but they are not taken from network manager.And last but no least: Is it possible that when using network manager the eth0 is enabled even no user has logged in?

OpenSUSE Network :: No Network Connection After Firwall Settings Changed / Get It To Work?

Nov 17, 2010

I deleted the firewall files "K09SuSEfirewall2_init", "K01SuSEfirewall2_setup", "S11SuSEfirewall2_setup" and "S01SuSEfirewall2_init" from "/etc/rc.d/rc5.d" in order to disable the firewall when rebooting.

As a consequence all network services are not working. I can't connect to any other machine nor to the internet.

I rebuilt the symbolic files based on the ones for runlevel 3, but still no network services are available.

Any suggestions how to make it work again? I'm using Suse 11.3.

OpenSUSE Network :: Configure A Connection With YAST As Well As With Network Manager?

Feb 1, 2010

Im new in this world of linux and suse. I have just installed the opensuse 11.2 in a Dell Inspiron 5160. Such laptop has a BCM4306 Wireless LAN controller. When I tried to configure a wlan connection, I found that the firmware was not installed. After looking in different forums, I installed the firmware b43. Now, my wlan card is abled to find the wireless of my router.

I have tried to configure a connection with YAST as well as with Network Manager, but both cases failled. Specifically, when I use Network manager, Im able to see in the applet my connection, how strong is the signal, but I see a yellow symbol (in one forum, such a box is shown with a green symbol).

I have check many time all about the secutity, encryption, and so one and all seems to be correct. But when I open the mozila firefox or the konqueror browser, no chance to surffer in internet. Now Im just a step to become crazy. The drivers are ok, the information about the router and the keys are ok, but in such a way, I am still harmloss.

OpenSUSE Network :: Network 11.3 - Connection Refused When Try To Connect To SSH From Another Machine

Sep 27, 2010

I installed OpenSuSE 11.3. The only "extra" package I put in after the install was VirtualBox-ose. The firewall is disabled. I gave the machine a static IP address. I can get to the Internet from the machine. I enabled sshd to start on boot with "chkconfig sshd on" and also verified the service is running on the machine. I can ssh user@localhost from the machine as well.

When I try to connect to SSH from another machine, I get a connection refused. I verify that the firewall is down. I also try to get to VNC -- same problem: Connection refused. I ping the machine for fun. If I try to SSH again, it sometimes gives me a logon? I would check the server logs for the connection refused, but I wouldn't know where to look. I started in /var/log/messages, but nothing seemed to jump out there. I also find it strange because I can RDP to a windows guest running under VirtualBox. The Windows guest uses Bridged Network and DHCP.

I also find it interesting that I sometimes type a "ping google.com" from the 11.3 box and it will just hang - no output. Then I open firefox and get to the internet. All of a sudden, ping starts to give output. Could this be a neetwork card issue? A configuration issue? I don't know where to start.

OpenSUSE Network :: Network Connection Fails To Go Past Router

May 16, 2011

So up until I updated from Opensuse 11.3 to 11.4, I hadn't any issues with my network connection. At least none worth mentioning. Once I installed 11.4, I've had weird issues with varying lengths of connection. Sometimes I can't connect anywhere, sometimes I can only get to the router, sometimes I'm 100%. I'd fiddle with YAST until everything worked. I honestly have no clue whether or not anything I did had any effect.

Enough of the iffy history, here's what's happening now. For the past few weeks up until last night, I have been at 100% connectivity. I never turned off my computer until last night (it just shut itself off, like the cord was unplugged. I dunno what happened, maybe it was my foot, maybe the PSU. I think it has happened before.). When I turned it back on, I was only able to connect as far as my router (192.168.1.1, a D-Link Gaming router that has always been very good to me). I could not make it to my modem (192.168.0.1, a Quest DSL modem. Once I can get here, then usually I'm good to go 100%).

I tried again this afternoon, and no change. I then get the crazy idea to unplug the ethernet cable from it's PCI-card home and return it to the onboard port (which I long ago declared defunct). Immediately after plugging it into that port, I ran "ping 192.168.0.1" and I started getting returns. I open up Firefox and try to load an external page, and nothing happens. I go back to the console that I was pinging from, and it had stopped. I start pinging my router, and no luck. What I conclude from my little experiment is that the router is not at fault.

1. It did not change at all between being at 100% and being at 0% after reboot.
2. I was able to get returns from the modem, past the router, for a brief period of time while using the defunct ethernet port.

Since I never had these problems before updating to 11.4, I'm inclined to believe that it was the update that started these problems.

Debian :: Network Manager Can't Share Network Connection?

Nov 13, 2015

In Googling around it appears that the Network Manager used to have a nice simple (obvious, logical, straightforward, intuitive, easy-to-use... ... can you tell I'm a bit surprised that there's not a simple button to do this, it's pretty common functionality ) option in the IPv4 tab called "Shared to other computers" allowing you to share your network connection with any computers connected to yours... kind of like this:

[URL] ....

Professor Google seems to indicate that this may have existed in Debian at one point but, I don't see this option anymore. How do I get it back (or is there another gui way to do this without editing the /etc/network/interfaces file... if there's no other way to do this... that's fine but I'd prefer an easy method of enabling and disabling sharing)?

What I'm trying to do... I have a Beaglebone Black connected via IP over USB. When I'm ssh'ed into the BeagleBone, I want to be able to use aptitude install to grab new packages etc... and that kind of requires access to the outside world. Everything I've found so far seems to to require a modification to the interfaces file but since (according to the interfaces man page) the preferred method is to use the network manager if possible... I'm trying to avoid that.

* It should be noted that I'm running sid with the experimental 4.3 kernel so... maybe in doing so I've shot myself in the foot?

OpenSUSE Network :: Network Connections Didn't Have Connection

Jan 14, 2011

I just finished a fresh install of 11.3 on an HP 7900 small form factor and have no network connectivity. In Network Tools eth0 shows the state as inactive. Network Connections didn't have a connection, so after letting it create one there is no MAC address. I copied and pasted the MAC address from Network Connections eth0, set up a static address with default gateway, netmask, etc. all set appropriately and rebooted. Still no joy.

I want this to get an address via DHCP, I just set up a static address for testing.11.2 sensed the NIC without issue, but 11.3 doesn't seem to like me right now.I wanted to get this deployed on 40 machines today. Oh well.

Ubuntu Networking :: Broadcom Corporation NetXtreme BCM5721 Network Card Randomly The Network Connection On The Server Will Stop Working?

Jan 29, 2011

I have a Broadcom Corporation NetXtreme BCM5721 network card on my server at work.Everything works fine for a few weeks, then randomly the network connection on the server will stop working. After it stops working, I will try to reconnect with the network manager, it shows a wired connection available, it shows the "connection in progress"animation, then the "connection disabled" icon.

I uninstalled the network manager and used manual configuration, but do you think the network manager was the issue? I can't have the server disconnecting randomly every few weeks with no way to know what the real problem is. Was there an issue with the network manager with 10.04?

OpenSUSE Network :: Set Connection With Network Manager?

Nov 27, 2010

with the ifup method everything works fine. But now I bought a wireless card, so I prefer to use the network manager to manage my connection. On my computer I need a static IP for wired connection, so I created a new wired connection and I called it "wired connection". But network manager always connect automatically to "Auto eth0" and I can't find how to modify this connection. Setting "wired connection" as default didn't change anything, probably becouse it need me to unlock the default wallet... Now, another problem, I really don't know why network manager applet doesn't appear on system tray, but I'm sure that I'm using it instead of the ifup method.

General :: No More Automatic Network Connection?

Apr 19, 2011

I am running Debian Squeeze on my net book ( ASUS 1000PE ) with an Atheros wireless nic. It has been running fine for months automatically connecting during boot to my hidden network but all of a sudden no dice.

If I use the Gnome network manager and "connect to a hidden network" and I am all set but when I am at the command prompt ( which is how I have it set to boot to) it is a few more steps. How can I get it to automatically load. I did not have any scripts set up before so I assume it is a service I need to turn back on that was turned off in error.

General :: Could Not Read Network Connection List

May 30, 2010

I recently (like yesterday) decided to put linux on my laptop because I'm annoyed with windows. However after formatting my hard drive I seem to have an error message at the same point in windows xp and linux when attempting to log on. I have abandoned windows completely and intend to only run Linux on my laptop however after I type my password the following message pops up:

There was an error setting up inter-process communications for KDE. The message returned by the system was:

Could not read network connection list.

/home/jtb360/.DCOPserver_Josh Laptop__0

Please check that the "dcopserver" program is running!

I have attempted to delete the only dcopserver file I can find and ran some suggested commands at the command prompt (I haven't used one since Windows 3.1) to remove an ICE file in hopes that it would recreate the file and run properly after reboot and neither effort prevailed. My next step is dropping it from escalating heights until it either works or dies.

Fedora Networking :: Bridged Networking And NetworkManager - No Network Connection Because Network Isn't Managed

Mar 2, 2011

I have installed qemu/kvm and created a Bridged network connection which works just fine(Windows 7 VM won't work in NAT mode.)

But when I try to use NetworkManager it says that I have no network connection because the network isn't managed, (I set the settings in ifcfg-br0 and ifcfg-eth0 to be managed)

The real problem is that now I can't use my VPN connections (I have many) in NetworkManager.

Is there a way to have both of these pieces of functionality?

I am using FC14

General :: Ubuntu Box Keeps Dropping Wired Network Connection?

Jul 11, 2011

I have an Ubuntu box, 11.04 x64, running on a Dual Opteron SFF box (iWill ZMaxDP... pretty old machine). Up until a few weeks ago, it was acting as a Windows 2008 Server, but i moved it to Ubuntu.

Anyway, the machine will not stay on the network for any amount of time, without falling off... I have changed network cards, cables, ports on the switch, etc, and nothing seems to work. I have a Windows 2003 box giving out DHCP addresses, and for a while, i actually tured that off and setup a second Ubuntu box to give IPs... it made no difference. The box gets an IP, and can ping outside for a bit (2 min or so) and then just looses connectivity... ifconfig shows it with an IP (i have tried both Static and DHCP config) and nothing seems to work...

General :: FTP Or Rsync Transfer Drops Network Connection

Apr 23, 2011

I'm using Scientific Linux on a laptop, connecting to a debian server on my LAN via a basic BT HomeHub router. When starting a file transfer with ftp or rsync from the laptop my connection is dropped, every time, after a couple of seconds. I have to reset my network adaptor and restart my network manager (wicd in this case) in order to get network connectivity back. I had a very similar problem before - [URL]. On this occasion my workaround was to replace NetworkManager with yast. I am now using SL though so no yast available, and I am not using NetworkManager any more anyway.

General :: SSH: Server Unexpected Closed Network Connection

Jul 4, 2011

In my case, it occurs intermittently when trying to connect using putty's command line client 'plink.exe' to a linux machine using ssh. For some testing purposes, a linux server is setup with 8K virtual ip addresses and the testing scripts will connect to these ip addresses through ssh using plink.exe. There will be concurrently 25 ssh sessions launched to the server. While it works for sometimes, it throws 'server unexpectedly closed network connection' error intermittently. If the same ip address is tried again manually, it works. While the ssh server is accepting connections, this error is thrown sometimes and unable to find out the reason from the logs. It is not that the ssh connection is completely blocked. It gives this error message while connecting to some of the virtual ip addresses but works some times.

The hosts.deny, sshd_config are tuned to allow the connections, allow more sessions etc.

General :: 12 And Windows 7 - Get Wireless Connection To Work On The Network?

how to get my wireless connection to work on the network. I don't see anywhere to go to see if the wireless adapter is even setup in Fedora. My other question is when I boot up and get the options to select the OS the first one is Fedora but the other one says it is other.

I think that is is booting up the recovery partion of Windows. I don't know how to change it so that it is looking at the correct portition. I know it has something to do with the menu.lst file but when I try to open it says that I do not have premission. I am not sure where to go to edit it.
