Hi, I try to use ike VPN under Linux.
For this reason I download last version of VPN and compile it.
Problem:
When I try to run ikec program with params I get system error:
cgi at iermolin-V3-771:~/data/data_lib/git_repos/ike$ *ikec -r rtk*

I can't resolve error by my self, but believe this is not hard for
mantainer ...
Ready to supply needed info.
P.S.
Options for compilation:
cmake -DCMAKE_INSTALL_PREFIX=/usr -DQTGUI=YES -DETCDIR=/etc -DNATT=YES
-DDEBUG=TRUE
Ubuntu version: DISTRIB_DESCRIPTION="Ubuntu 13.04"
One more note:
If I use graphic interface - all works fine and I'm get able t oconnect to
VPN server.
But I want to automate connection and so try to use ikec programm.
