I installed vpnc package under RHEL 5.1 64 bit and its working fine. but it is showing frequent disconnectivity issue. I did added the script for respawning:

2. How to make the connectivity stable?
Using a USB ISO, I recently installed Debian 8.0 Jessie (64-bit, Xfce DE) to a new computer. I usually lose my Wifi connection after 1-3 minutes when donwloading/uploading at around max. speed 4 Mbps/512 kbps. Sometimes it will last 15+ minutes.
When lightly browsing it can usually stay connected for 15-30 minutes. I have to disable and enable Wifi using NetworkManager to connect again. If I remember correctly, there were problems with the Wifi connection even during the installation of Debian.
This Wifi USB adapter works fine on my old computer with Debian 7.7 (32-bit). No problems with the Wifi connection yesterday on my old computer during 10+ hours of activity.
This Wifi adapter also works fine on this new computer when I boot from a live USB (Rescatux 0.30.2) downloading and uploading at max. speed for 1+ hour.
I already tried some suggestions I found online, but they didn't work:
* changing Wifi channels between 1, 6, 11 in my router settings
* changing WPA-WPA2 to WPA2 in my router settings
* ignore IPv6 in NetworkManager
* change probe_wait_ms from 500 ms to higher value by adding Code: Select alloptions mac80211 probe_wait_ms=1000 or Code: Select alloptions mac80211 probe_wait_ms=3000 to /etc/modprobe.d/mac80211.conf and rebooting
* disable Power Management for Wifi adapter (not supported)
* ...
I can also post the output of commands from Rescatux or my old computer if needed.
Output of commands on Debian 8.0 64-bit (I edited out some info, MAC, ...; not sure if that is important):

My wireless card disconnects frequently and sometimes it won't even connect at all. I've googled the card and the driver and it looks like others are having similar issues as well. [url]-[url]
My lspci | grep -i network is as follows

In fc10 & fc11 everything worked well with vpnc.
With fc12 vpnc starts allows me to connect to my work site then everything works fine til I try and start a remote desktop connections to a windows client use tsclient. All I get is a blackscreen and my laptop is hung.
At work without the vpnc it works fine if I start the vpnc from nm it performs the exact same way and I get the blackscreen.
I have disable selinux.I also disabled the firewall
there was another gentlemen on here with the same issue.
The only way out is a hard reboot and there are no messages in the logs that say there were any problems.
I've been trying to connect to my office Cisco VPN several time using the network-manager-vpnc GUI in Ubuntu Karmic with no success. I read a couple of articles and i tried using the direct command line way:
Code:
sudo vpnc office
with the following /etc/vpnc/office.conf file:This is fictional data
Code:
IPSec gateway vpn.office.com
IPSec ID office
IPSec secret 0ff1c3
which worked perfecly.
So i went back to the Network Manager GUI way and i used the same credentials. Same fictional data I got a libnotify message telling me it couldn't connect.Anyone know how i could troubleshoot this issue? Would be great to have it integrated in gnome instead of running a background command which is not tracked by nwm.

Since I installed FC11 vpnc stop working. I get "vpnc: no response from target." I tried running it with "strace" and the reason is a timeout: poll([{fd=3, events=POLLIN}], 1, 4000) = 0 (Timeout)
I tried google and adding "NAT Traversal Mode cisco-udp" to the config file works for some people but not for me Does anyone had experience with vpnc 0.5.3 in FC11?
I have been trying to connect to my University's VPN Server and for some reason vpnc fails. I have configured the vpn settings the same way I did for the past two years. They worked properly on Fedora 12 and 13, but for some reason fails on Fedora 14.

Problem with fedora 13, I am no longer able set up a virtual private network using vpn. The following error message appers:
"/usr/sbin/vpnc: no response from target"
No problem when connecting with ubuntu or windows.
how nobody else could have run into this in the meantime. [URL] Two friends of mine are having the same issue on Ubuntu-11.4-machines. In short: Connecting to the Cisco-VPN via shell-command "vpnc" works flawlessly, whereas NetworkManager just doesn't connect at all. We had this working in older versions of Fedora/Ubuntu about some months ago...

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
Quote:
Failed to bind to 0.0.0.0:500: 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?
Its been like this since fedora 12, in fedora 11 its no problem, i hope it will be fixed in fedora 13 and i am waiting..., and after fedora 13 released the problem is still the same...
I use Intel 3945ABG. wifi connect with no problem and after few seconds its disconnected, and re-asking my saved password (which is stupid since i save the password so fedora won't ask me that stupid question again).

View 1 Replies View RelatedI am using KNetworkmanager-vpnc to VPN back to the office from home, the vpn connection works fine - for 15 minutes then I am disconnected. I am fairly certain that this is related to the Phase 1 key lifetime limit. The Knetworkmanager-vpnc GUI does not provide a location to enter this information. I think I found the config file that holds the connection information at /home/<user>/.kde/share/apps/networkmanagement/connections/ I just don't know the proper syntax to put in the file to specify a key life limit. Anyone out there know how to do this? I am using Fedora 14 x64 with knetworkmanager-vpnc 1.0.9-0.28.

I am running FC12 64bit. Frequently the system hangs usually one app - Thunderbird. If I have Firefox up also, it seems to run fine. The light indicating disk access is on almost constantly. Is there a way to find out what process is accessing which disk? I have 4 hds installed - 2 IDE and 2 SATA. I am having a similar problem trying to do a reboot - it does not reboot within 15 minutes. I need to hit the reset button.

View 6 Replies View RelatedI had installed Fedora 12. Initially it used to work fine.

View 5 Replies View RelatedI'm having issues with my wired network. After about 5-10 minutes of turning on my machine, the network will drop out. Sometimes rebooting my pc or router will fix the connection, other times it will have no effect. Also, sometimes the connection will completely disconnect, other times it will appear to be connected (i.e. the network icon will indicate that there is a connection), but trying to ping a remote server or the router will fail.
This problem first showed up on Fedora 11 64, however I've just installed Fedora 13 64 and that hasn't helped. I'm using a brand new NIC (I've tried using the onboard NICs). The machine also has Windows 7 installed, which is able to connect just fine. Apart from changing NICs, the only other thing I've tried is switching from dhcp to a static IP address.
I've seen many threads of this type, but I didn't see anyone simply say what the problem is. There's got to be something happenning to make it disconnect, and then something else makes it so it can't re-connect.What I get is that it connects for some time (maybe a short time, maybe a longer time) but eventually it just disconnects. When I try to re-connect wpa_supplicat log says simply it's trying to associate with the AP; it's associated with the AP; and then it's disconnected: CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
It is a home-built with AMD64 and a D-Link DWA-160 A2 (Atheros AR9710) and Netgear extreme 300 router AP. The router log shows it is in fact connecting for a short while only to be disconnected at my computer's request.This is Fedora 13 out of the box (sort of!) except that I have the development repos and the updates repos and the RPM fusion repos installed. I have NM applet running. I use one called simply "network", and also one called "control network devices". but they all lead to the same result that it can't reconnect. If I play with it enough doing any variety of changes I can eventually get it to reconnect, but there's no telling what action was the successful one. I just think it reset whatever was bothering it. But, as I saw another thread describe, if I delete ALL network connection definitions and reboot, it will find the network and it will connect. But sooner or later I'll be back to where it disconnects.So, does anyone actually know what the major malfunction is? It should have been identified and qualified and quantified by now so that there's a simple write-up of cause and fix. But thru all my googling I can't find anything definite. If anyone has some good answer please post it so we all can benefit.
I'm using BSNL(India) EVDO service. I got ZTE dialer for Fedora and it works fine. But it has started causing error which was not seen when I installed system freshly. It's just been a week and whenever I disconnect ppp interface, xmessage window open and I see error message.

On F12, I can connect and can do some activities, but so far I noticed the following (show-stopping) issues:Attempting to connect to an Oracle database using either sqlplus or TORa hangs and eventually times out. I tried both the 11G and 10G instant clients.Copying a file to the host via a smb:// mount in nautilus freezes. An empty file is created though.
A rdesktop client opens a "black" window and goes no further. I attempted to downgrade vpnc on my F12 workstation from vpnc-0.5.3-4.fc12.x86_64 to vpnc-0.5.3-3.fc11.x86_64 to no avail. I also downgraded libgcrypt too and this didn't help either. Moreover, I upgraded these to the F13 rawhide version - still no luck.
I also confirmed on a F11 virtual machine that these work and that it doesn't work on 2 x64 and 1 x386 F12 machines. (The configuration and the host are the same in all cases.)

View 2 Replies View RelatedI've seen a problem staying connected to a Cisco VPN, this goes back a number of years.I was running 8.10 and it was fine.After I moved to 9.10, the problem started happening.My VPN connection to work would drop after 8 hours.I looked around for a while and ended up compiling the cisco provided client which works fine (but is a pain).I've been running 9.10 on my work laptop, and it experiences the same problem using vpnc, but I've been dealing with it because it's easier than using the Cisco client.
I installed 10.04 on my work desktop, my home desktop, and a personal laptop that was previously running 8.10, and all experience the same problem with vpnc.I even go so far as to keep one terminal open with a constant ping all day and it still drops after about 8 hours. A couple of others at work experience the same problem using vpnc. This is not a problem using the Cisco provided client, or running it on windows or os/x.Has anybody else seen this, or have any ideas on what I can start looking for to get this addressed?
