Ubuntu :: KVPNC Dropping Out After 4min 15 Seconds?
Nov 8, 2010
Since upgrading to 10.10, I am having some difficulties with KVPNC. It used to work well. It seems to disconnect after precisely 4min 15 seconds. The log from the window is shown below with the sensitive bits redacted.
Code:
info: Reconnect after connection lost enabled, reconnecting...
debug: vpnc: /usr/sbin/vpnc
info: Gateway hostname (<redacted>) resolved to "<redacted>".
debug: vpnc version (major): "0"
debug: vpnc version (minor): "5"
When I KVpnc into a client VPN I connect, but every 4 minutes, or so, I am reconnected. Since I'm RDPing into their server remmina (and rdesktop too) loose their mind and I have to manually reconnect to the server. The attachment Screenshot-8a.png shows the display KVpnc uses to describe this when it happens. /var/log/syslog shows it happening twice here:

As soon as i'm starting to copy a large file enough file (>700Mb) to my ubuntu box (connected to an Asus router via wifi) from a Windows 7 client (connected to router via ethernet cable) i get a dramatic drop in speed. upload starts at 1,0Mb/sec with a ping to ubuntu box at <1ms, and in 2 minutes it drops to 200kb/sec with a ping of over 1000ms! The ping increases with every second in a linear progression.
To exlude router as a possible problem copying to a windows 7 notebook connected to router via wifi results in an average of 2,7Mb/sec with an average ping of 150ms.

i was very cautious in installing 11.2; i had previously evaluated sled10sp3, it was great but for some reason it never connected to a dhcp server to get the internet. my fear from installing 11.2 was that i blindly trusted lilo for years as my boot loader (dual booting with xp)
so i took the chance and installed 11.2 with lilo. didn't work; so i went back and installed graphical grub; didn't work either; then installed the system again but with the option "use trusted grub" (which is a text-only boot loader) which worked like a charm on my system.
the thing is, that my system overall boots quickly, except in the part when it starts detecting the hard-disk; which takes 4 minutes detecting the disk and partitions. when it "fails" detecting or doing something with the disk, it continues to boot rapidly then.
My system specs: - opensuse 11.2 & xp - default kernel 2.6.31.5-.0.1 using gnome desktop 2.28 - amd athlon 64 x2 dual core processor - 2.5Gb Ram
I ran the Kvpnc wizard and imported my config file and when I try to connect it always says connection timed out.I can connect to OpenVPN without a problem using the terminal, all I can say is kvpnc is a real pain and I don't get why I can't connect with it if I can connect without a problem from the terminal.I thought this was suppose to be a simple GUI that you just imported your config add in your cert and the cert path and that's all.
I am using KVPNC (recommended by the VPN owner) on Ubuntu 9.10 using my Universities direct Ethernet connection.
I have downloaded all the .ovpn scripts to a directory. I have downloaded KVPNC from the repository (apparently for 9.10 you do not download from the KVPNC website).
I then use sudo kvpnc and select a server (since there are many based on the .ovpn files).I click connect and the script works and tells me I have a connection. See below for an example. All appears to work.
But when I actually load any Internet program e.g. Firefox it cannot find a website.This happens for all servers which have different locations around the world.When I disconnect KVPNC I still have no access. I have to remove the Ethernet cable before it works again.
debug: Connect try requested, profile: Stockholm, type: OpenVPN debug: openvpn: /usr/sbin/openvpn debug: Support for TUN/TAP found (compiled into kernel or kernel module already loaded). debug: Default interface: "eth0". debug: IP address of default interface: "my IP address". code....
I realise there are errors e.g. the /etc/resolv.conf must be a symlink but have tried doing this and still have exactly the same issues.
I set up an ssh server and configured port forwarding on my router so that I can access the ssh server from the internet. This is working fine, also from within the LAN.
Additionally this machine should be connected to an VPN Server on the internet. Again, this is working. I get connected, the tun interface is coming up, etc.
The moment the VPN Connection is established I can not connect to the SSH Server anymore from the internet, LAN ist still working fine. I guess it has something to do with the route that is set by the VPN Connection?!
So my question is, what do I have to do to reach the ssh server from the internet while the ssh server is connected to an VPN Server itself.
ifconfig without VPN

I was using KVpnc from 10.04 and today I upgraded to 11.04, however I am facing a lot of issues, here are a few
1. The minimized KVpnc disappears after connect, no clue where it goes, the other go to Unity Side Bar.
2. Once connected since I cannot see it, how do I disconnect it? I tried opening it from applications again, this time around it says it cannot resolve my VPN server.
3. I see multiple instances of KVpnc running when I do a ps -ef
I use KVpnc and openVPN to connect to my desktop at work from my laptop at home. This works fine, I can reach my desktop at the office from my laptop at home. The only problem is that when the Vpn connection is active I cannot use a browser on my laptop. In fact, I cannot connect to anything outside the office Vpn (like mail, chat etc).
I suspected it had something to do with the DNS servers at the office not being reachable from the Vpn so I added my "regular" DNS servers to the /etc/resolve.conf used when the Vpn is active, I added two lines in total on the form "nameserver <ip-address>". This did not solve the problem. I have searched the KVpn forums without finding anything, and the same goes for the openSUSE forums. Does anybody else experience the same problem?
Is there any way to run successfully umtsmon with kvpnc? Trying to build up a connection to a VPN provider using his profile openvpn and kvpnc. It connects as "low level connection" , the indicator of kvpnc remains red, but then kvpnc would not pass the network traffic through umts-mon (or better vice versa, umtsmon doesn't). In principle I would like to pass both interfaces (wireless, umts) through vpn.
So trying to use skype. all is going well, except when I speak or even as soon as the female voice from the testing service comes on, the input volume automatically starts dropping. this is an issue, as my voice sounds quieter and quieter as the call progresses. Any thoughts or how I may lock it at a higher input volume?
I've installed Samba on my Home Theater PC but none of my other computers can stay connected to it. Sometimes it drops connections right away, other times it takes several minutes.either way, a pc will never stay connected longer than 20 minutes.
I have the following OS's in my home OSX Snow Leopard Server 2003 Server 2008 Windows XP
Lately about half the time I boot up on 9.10 it stays at the tty & asks for my login & password. It will just stay there for about a minute or so & thenboot up normally whether I enter anything or not. I have it set for auto-login & it never was a problem before. Some times it boots up normally without going into the login screen at all. The only thing that is different is one of the 5 year old kids I let use the computer for the internet & the computer doesn't always get shut down right(turn the power off). I suspect that has caused the problem but it happens now even when I know its been shut down right.
Just installed kubuntu 10.10 on a dual boot with winxp on my asus r101 netbook. wireless connects perfectly, but after roughly 30 seconds, i cant access any address or ping an url or ip. however network manager says im still connected. so i click on network manager, and click on the wireless connection, it then reconnects in a couple of seconds, and all is good again. i carry on browsing, and 30 seconds later the same happens again!!! my wireless signal is fairly week, however connection works everytime and in xp this is not an issue.
I'm using Ubuntu 9.04 64 bit on an Asus laptop and the wireless connection disconnects randomly for a while and keeps searching for the signal. When it finds it I have to put in my WEP key again to get it to connect sometimes only once or sometimes 2 or 3 times. This is getting quite annoying.
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
This is weird. I will be working on the internet with several tabs open and all of a sudden the pages won't update. I can't go anywhere - it's like I lost the connection. I am also downloading bittorrents with uTorrent running with WIne and that doesn't seem to be affected. I also have gPodder and I tried to update podcasts with that and it also hangs up as if it can't connect. The only way I have been able to solve this has been to reboot (which I just did).
Having major wireless issues with Linux. I have DSL and had a Westell router/modem combo and my wireless would stay up for no more than 15 mins at a time even while idle, and in order to get wireless back I have to reboot and then I can get another 5-15 mins of wireless before it drops. When it drops it prompts me for my wep key and wont accept it yet if I reboot it catches the wireless right away for a very short period. So I go out today and spend over $100 bucks on a Netgear dgn2000 thinking it would fix the problem... Nope I am still in the same boat as I was with the Westell.
I am not seeing my router model listed under the wiki link sticky.. (Edit) thought I installed ndiswrapper, it was it was in my downloads anyway I can't install it I get the following error (Not a valid driver .inf file.)I have tried 3 distros and have the same problem. I went to Netgears site in search of Linux drivers but all I found was the firmware updates. Could some one please shed some light on what I need to do to get up and running?This is a new laptop and I am pretty annoyed with myself for formatting it out of the box rather than reading up a bit more about Linux (been using for one month).I don't understand it Ubuntu 10.9 ran wireless perfect on my older system, (full install) and I have no trouble with my lap top that is running Windows.I really hope to get this resolved I really enjoy Linux and I don't want this to be the one handicap which would force me back to Windows, that would be very upsetting
when I try to use a messenger program on ubuntu, the messages keep dropping out, I have an old-ish netgear router, what I have done is setup a virtual-box with windows xp and i'm having no problems with msn messenger under virtual-box at all, does ubuntu not like old-ish netgear routers?
I was having trouble with my wireless connection, it was dropping every 5 minutes or so after upgrading to 10.04 and ran across a thread where someone recommended entering
After entering the command I have lost all ability to even use my wireless ability even if it was for 5 minutes. Now I am using a different kernel, internet still drops every 5 minutes, but would love to get my internet up and running again.
Lately I have been using my window's partition due to the fact that 10.04 drops my wireless signal every 5-10 minutes, but today I downloaded the new updates and that seems to have fix the issue with the dropping of the wireless connection. Now the only problem is the internet is so slow when trying to go to webpages it times out. I have opened up firefox gone to about:config and changed the necessary lines, but still dreadfully slow.
get this working all of the time instead of the constant dropping that I experience -- i've read a lot of the posts and think i have the right driver installed but there never seems to be a major improvement.Running a p4 2.8 ghz system on lucid and have the most recent kernel installed.Thought I'd give it a last attempt with help before chucking it and getting an adapter that's more compatible
I'm running ubuntu 10.04 on my laptop with broadcom BCM4322 wireless card.Basically what keeps happening is my wireless will stop working, then network manager will notify me that I have lost signal. It will then try and reconnect, but it never seems to be successful. The only way I can get the wireless to work again is if I disable wireless then re-enable wireless (or do a complete system restart).
However, it does not seem to have this problem at home. The only difference I can think of from home and school is either encryption types (the university uses WEP, I use WPA) or the fact that at home there is only one access point and at university there are multiple access points all with the same SSID.Anyone have any idea how to make my laptop stop dropping connection all the time?
I just noticed this issue today but when I unplug my laptop from its adapter, the battery loses 44% of its battery immediately, Is there any way of solving this?
I have search and there is similar topic but for 9.10 and the problem contains "UUID" [URL]I was wondering if the fix listed there will help my problem.
I'm having a problem with the wireless on my Asus EEEPC 1000HE using Ubuntu 110.04. Digging into the laptop forums, it says there is a problem with wireless on some models of the 1000HE, but it is not the same wireless device and my wireless problem doesn't seem as bad as listed, so I think it's a different problem. But my problem is that if wireless drops for any reason, it will not start working again unless I either reboot the computer or click the wireless icon in the systray, click disconnect so it stops flashing (like it's trying to reconnect) and then suspend my computer or log off and back on. And it only does the latter because I added a file located at /etc/pm/config.d/00sleep_module with the one line that reads SUSPEND_MODULES="rt2800pci" (my wireless driver) So that one line seems to cause wireless to get a fresh connection after suspending (or something. I'm not a very advanced LInux user). I've tried running the command "sudo/etc/init.d/networking restart", but that does nothing for me. I'm not sure what other command to try to see if can fix it.[URL]
My network seems to be dropping every few minutes to few hours. There are a lot of networks in the area (apartment in NYC) and I wonder if it might be due to competing traffic. Any ideas for how to tell what channels other networks are on? or other modifications to router settings that might improve performance in this situation?Additionally the "Invalid Misc" in iwconfig is counting quite quickly.
When booting I am being dropped to initramfs/busy box heres the error: Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline) - Check rootdelay= (did the system wait long enough?) - Check root= (did the system wait for the right device?) - Missing modules (cat /proc/modules; ls /dev) ALERT! /dev/mapper/dev-root does not exist. Dropping to a shell!
