[edit] VPNC problem with tun
Dear Vserver users,
I know some explanation was given about the TUN device on a vserver with openvpn
I'm trying to get vpnc to work on a virtual server. I can't use openvpn because I need to connect to a Cisco PIX that only understands IPSEC.
I've created /dev/net/tun with apt-get install uml-utilities
- cd /var/lib/vserver/<myopenvpnserver>/dev/
- ./MAKEDEV tun
as suggested. I don't use a tap interface
my vpnc.conf is IPSec gateway x.x.x.x IPSec ID somename IPSec secret somepass Xauth username some username Xauth password some pass
Now when i try to do vpnc-connect on my vserver, I get : vpnc: can't initialise tunnel interface: Operation not permitted
chown 777 /dev/net/tun doesn't help
Please help me out here
[edit] About memory limits for a guest
Since RSS is used to limit the memory resource for a guest. If processes in a guest use share libraries (libssl.so, libpam.so, etc...), are the shared parts of RSS in every process counted as the memory usage? In this situation, if I set the RSS hard limits to 256M, in fact the guest can not use up to a 256M real physical memory, maybe much less than 256M. Because some shared part are counted as privately used. Is that true?
[edit] How do i install nagios-plugins on a Gentoo guest?
This seems to be another play on the Problamatic_Programs 127.0.0.1 issue. If it is not a FAQ, I suggest that this is not either but instead be merged with the other onto Problamatic Programs.
Perhaps there should be a FAQ starting point entry for localhost / loopback issues pointing to a full page. I know I took up a lot of Bertl and other's time on IRC today due to a backlog of confusion in my mind about it which had lead to a configuration that was tricky to troubleshoot.
