Comment # 3 on bug 1203842 from Cosmin Tanczel

Since openconnect seems not be be allowed to run as root*, I installed setcap
(libcap-progs) and did a setcap cap_net_admin+ep /sbin/openconnect


*openconnect[2210]: SIOCSIFMTU: Operation not permitted

Now the operation not permitted error doesn't appear anymore but I now I get:
(vpn0)]: invalid IP4 config received: no valid IP address/prefix
(vpn0)]: did not receive valid IP config information

It seems quite related to this one:

Can anyone take a look?

Thanks!
