Ubuntu Networking :: Establishing A VPN Connection - Kubuntu 10.10 - 64 Bit

Apr 15, 2011

I have a problem with establishing a VPN connection, it's driving me nuts already. No matter what I try, which packages I (re)install, or how many configuration settings i change.. the result is always the same (see syslog at the end of this post). On the same machine, but on a different harddrive, I have installed Windows 7. The VPN connection works without any problems on this system.

I played already with KNetworkManager, NetworkManagerm, KVpn and so on. Further I re-installed each VPN- and network packages multiple times (eg KNetworkManager, NetworkManager, network-manager-pptp, pptp-linux). Further I tested almost every possible VPN configuration (PAP,CHAP,MSCHAP(v2),EAP,MPPE, stateful encryption, no password, BSD compression)... My syslog is as follow:

Apr 13 18:15:02 defcon-inc pppd[3721]: LCP: timeout sending Config-Requests
Apr 13 18:15:02 defcon-inc pppd[3721]: Connection terminated.

Ubuntu Networking :: Updates Lead To Failure In Establishing A Wired Connection

May 21, 2010

One of the (many many) problems that I had with Ubuntu 10.4 was that I wasn't able to connect using a wired. It really came to me as a huge surprise, because that's a problem that I have never encountered. I had dealings with wireless-issues in the past. But never a wired connection failed. The thing is that we (in the dormitory where I live) had a network problem recently. A hardware piece got fried and we weren't able to replace it for about 3 weeks (go figure :X ). But in the past 3 days or so we're back online. The thing is - none of my neighbours (all of them are using Windows) has network issues now. Usually it was on the contrary - I was the one who had beautiful connection while they had to deal with a load of d@ng. That said - I made a fresh install of Ubuntu 9.10. The problem got resolved and I was as happy as a chick during her first wedding night with Don Goivanni in her bed. BUT after I updated (note - update and NOT upgrade) my system, I was suddenly unable to use the wired connection. The strange thing is that the NM says that I am connected AND I even get some short bursts of network traffic (last for 2-3 seconds) but usually not enough to load even a simple web page. Ping always returns 100% loss no matter how long the package burst lasts. I have slept this night for about 3 hours looking for a solution. None has been found so far. I don't have WAPs at home so wired connection is the only way for me to use this modern thing called internet.

Fedora Networking :: Establishing A Vpn Connection Using Vpnc / Error Failed To Bind To Address Already In Use?

Nov 24, 2010

I am having difficulties in establishing a vpn connection using vpnc (or NetworkManaager-vpnc).

As long as the openswan IPsec daemon is running, vpnc-helper quits with the error message


Failed to bind to Address already in use
[user@computer ...]# vpnc-helper --local--port 0

If I use NetworkManager-vpnc, then establishing the connection simply fails.
Using the --local-port 0 option does not change anything.

If I stop the ipsec service (service ipsec stop) then establishing the connectiong works, both with NetworkManager-vpnc and the console tool, but apparently the network traffic is not routed via the VPN - in my case this means that I cannot access hosts within the vpn and stuff.

Funny thing is - on my notebook from where I connect via WLAN, everything works fine. With Fedora 13 everything works fine, too.

Does anybody have an idea how to enforce that the vpn connection is actually used?

General :: Windows - Establishing A VNC Connection Through A Firewall?

Jun 28, 2010

What's the best way to establish a VNC connection to a computer located behind a firewall/router, to which you don't have access? I have a home Linux computer on a Comcast connection, which explicitly blocks incoming requests, so I can't hit the IP directly, but I'd like to remote into it from an arbitrary Internet connection. How would I work around this?

I've witnessed some commercial products, such as one employed by Dell tech support, which appears to use a public web server, which you visit from the target computer in order to "expose" it to an incoming VNC connection. Is there anything similar that's free/cheap for personal use?

Ubuntu Security :: Establishing A SOCKS Proxy Connection At An Internet Cafe

Aug 7, 2011

I've got my netbook set up so that I can run a SOCKS proxy via my desktop machine. This works fine at home, but I'm wondering what happens at an internet cafe with public wifi.

Specifically, the connection needs initially to be set up with an ordinary direct internet connection so that I can log in to the cafe's router. I'm concerned that when I then set the network proxy to SOCKS host, the router will cease to recognise me and will disconnect me. This particular detail doesn't seem to have been covered in any instructions that I've seen (maybe I haven't looked hard enough).

i want to remote control my laptop with my phone via terminal

im trying to use this guide to connect my android phone to my fedora laptop via ssh and vnc, but the connectbot ssh connection is timed out


however, this guide assumes a running ssh and vnc server, which isn't trivial to me, i think i have established these, but i don't know how to test it

also i am not shure if my router and firewall configuration is correct, i disabled wan blocking but didn't enable remote config management on my rooter, is that correct?

General :: Establish Internet Connection - Fail In Kubuntu ?

Mar 18, 2011

I have a new clean Kubuntu just installed. I have a wireless router (access point) that I used to connect to internet in Windows 7. I plugged the internet cable into the router, connected computer to wireless network, created a new broadband connection using login and password given by the provider, and internet connection worked. I want eventually to have the same on Kubuntu.

Here are the ipconfig output from Windows with the working internet configuration:


I want to have the same thing on Kubuntu, but before that I want to be able to have at least the direct cable connection working. Had no problems setting it up on Puppy Linux, but fail in Kubuntu. Wireless connection with the router is no problem, it worked right away.

After plugging the internet cable to the network card I have this:[url] I tried to set up new wired and dsl (not sure which I need, probably DSL as it has the login and password) connections in the Network Connections window but nothing works.

Below are some internet configurations that I guess are needed:

Debian :: Why Not Establishing Official User Based Repository

Aug 19, 2011

One may argue that Debian is going mainstream being officially supported by Linux Mint. The chances are high that many users may change from the Ubuntu to the Debian base. By now especially Ubuntu's PPA has grown to a huge respository offering almost anything an user would need. But how does that look like in a Debian world?

There are several approaches to establish a "Debian PPA", amongst them debppa, but there activity is low not to say that they are almost inactive and orphaned. As coming from an Archlinux and Ubuntu perspective I do not know the Debian perspectives enough to reason this but am still curious to know about your motives not establishing a userbased repository.

Fedora :: Re-establishing Soft RAID5 From Previous Install?

Fortunately my admin had recently backed up the /etc directory. When FC14 failed, he reinstalled FC14 on the SSD. Is there any way for me to re-establish the RAID-5 drives, since they were not affected?

Server :: Connection Blocked To Kubuntu Server Outside Network

Jul 14, 2010

I've recently turned an older PC into a linux box for the purpose of creating an online server with ftp and ssh capability and file sharing. I've installed Kubuntu 9.10 and I'm trying to ssh to the computer from outside the network.I've install the openssh-client and openssh-server and I've created a static ip address, which works fine. I cannot ssh to the machine from outside the isp using either the direct ip address or hostname. The machine is connected to the internet via a Linksys Wireless G router, and I've edited the configuration settings to keep port 22 open for connect in the port server utility.

I've checked the ssh_config and sshd_config settings and port 22 is the default connection port, which is supposed to be open. I've run ifconfig and everything looks fine. I can connect to the computer using a machine connected to the same router, but other computers cannot access it. I want it to be visible to everyone.

Ubuntu Networking :: Setting Up Bluetooth Connection Between Two Computers Throws Connection Refused (111)

Apr 3, 2011

I'm trying to create a PAN (Personal Area Network) using a laptop (Siragon ML-1040) and my desktop computer, but I get the Connection Refused (111) error.

Blueman doesn't detect any network service between the two computers unless I start PAND on one of them and then it detects the NAP service. That, only after I enable the NAP/Workgroup services on the Services submenu in Blueman. However, it doesn't work neither with the NM plugins or without them (dhclient and that other one I can't remember the name of).

Any clues over here? I'm using pand 4.91 and blueman.

Ubuntu :: Point To Kubuntu CD Instead Of Kubuntu Repository?

I would like to apply KDE on my Kubuntu because the current one blew up. But each time I to sudo get-apt it seems to be fetching from the cloud. Is there a way I can make it to read from my local Kubuntu CD? I have both Ubuntu 10.04 LTS and Kubuntu Live CDs.

I believe the local disk read should be faster to translate than to bite the bytes across thousands of miles over the wire right?

Ubuntu Networking :: Kubuntu Can't Set Up Any Network Printers

Feb 15, 2010

I've had Kubuntu 9.10 32-bit running on my laptop since it came out, but in the past month all its networked printers have disappeared from the configuration, and I can't set up any more. I've been through the forums again and again and cannot fix it. I've installed and reinstalled lots of packages related to CUPS but it doesn't seem to make a difference.I'm not sure what has happened, but I have lots of clues. Since I'm reaching the limit of my know-how here, I'll just list all the clues.

I'm pretty sure the problem is in my Kubuntu laptop, because in my SOHO setup I also have a Kubuntu 9.10 desktop (this time 64 bit) connected to a printer, and I have successfully printed through that from both a Windows XP laptop and a Xubuntu 9.10 box.On the Xubuntu 9.10 box, I just asked for the GUI print configurator and it automatically detected the network printer. No muss no fuss.But on the Kubuntu laptop, when I go into the print configurator, here's what happens:

- it shows two options, "new printer" and "server settings" (image a.png)
- entering "server settings" everything is greyed out and unchangeable (image b.png)
- entering "new printer" shows only one option for a connection, "other" (image c.png)
- after entering the address of a printer i know works (image d.png) the configurator has detected the printer (image e.png)
- but then attempting to move forward it crashes with no explanation.

Running the non-kubuntu version of the configurator GUI provides a bit more information before it fails. When I try to access the desktop with the printer attached it wants a username and password. (which wasn't necessary for the two client machines who successfully printed.) And at the end of the process there is an error: "there was an error during the CUPS operation: client-error-forbidden".

Two more clues:
- when I try to go with my browser to localhost:631 the browser can't establish a connection
- but I can see the cups page on the printer's host machine at no problem.

Ubuntu Networking :: Getting Wireless Setup In Kubuntu

Nov 23, 2010

I am a new Linux user and Maverick Meerkat happens to be my first Linux system i installed. Setting up wireless was pretty easy in GNOME as it displayed my wireless system and i just entered the WEP key and i was all set.I decided to install KDE. After i installed KDE i wanted to setup internet There. However the KNetwork manager is not as friendly as Network Manager. It does detect my wireless router, but after i enter the WEP key it does not get connected.

It was asking me all sorts of question like SSID which i did not use in GNOME at all and neither do i know that information.I tried wcid network manager but removing network-manager and knetwork manager.wcid did get connected to my wireless but it was unable to acquire my IP address. (please do note that both k-network manager and wcid network manager work well with wired internet connection). Could you please help me setup internet in KDE? the truth is internet responds better in KDE than GNOME for my computer somehow.
