u-995 · 02-20-2014, 04:30 AM

Hello,

Yesterday i installed these on my Kali linux (Debian) machine to get openvpn working:

Quote:

apt-get install network-manager-openvpn
apt-get install network-manager-openvpn-gnome
apt-get install network-manager-pptp
apt-get install network-manager-pptp-gnome
apt-get install network-manager-strongswan
apt-get install network-manager-vpnc
apt-get install network-manager-vpnc-gnome

But today I can't seem to get my eth0 to et to work anymore... it doesn't do anything in wireshark neither... i can put it up and assign it an ip, but that's it... can't ping. I haven't done anything else with the vpn packages...

Since it is saying that the link is down, I'd say no, this doesn't have anything to do with openvpn. I'd check the switch/hub it's hooked into and see if you have a link light. Could be the switch/hub, cable, or local ethernet port has a physical problem.

oh boy, yes, this morning i switched the cable to another port on the router and it was fixed, phew :s
(last night i also sat in an extreme position with a tight cable)

i HOPE this was it ... waaw ... my first embarassing thread, keep you guys posted
