When not using NTP you may need to set your system time manually. You have two options to set time and date on your RHEL7 linux. First option is to use date command to do this job or engage dedicated systemd timedatectl command. By default and without any arguments timedatectl will display a current time, local, universal and RTC times:
[root@rhel7 ~]# localectl
System Locale: LANG=en_AU.iso88591
VC Keymap: us
X11 Layout: us
[root@rhel7 ~]# timedatectl
Local time: Thu 2014-09-04 18:30:11 WST
Universal time: Thu 2014-09-04 10:30:11 UTC
RTC time: Thu 2014-09-04 10:30:10
Timezone: Australia/Perth (WST, +0800)
NTP enabled: n/a
NTP synchronized: no
RTC in local TZ: no
DST active: n/a
The following linux command will list all available locales currently available on the Redhat 7 system:
[root@rhel7 ~]# localectl list-locales
The list of all available locales on your system my be quite long so use grep command to narrow down your search. Bellow command will display for example all German available locales:
Instead of changing a hostname on your Redhat 7 server manually by editing /etc/hostname you may preferably use a dedicated command hostnamectl to do this job. By default when no other options are supplied the hostnamectl command will display basic information including static hostname:
[root@rhel7 ~]# hostnamectl
Static hostname: rhel7
Icon name: computer
Chassis: n/a
Machine ID: 75387b56d72b44b380810499805ec28a
Boot ID: 6ad251d0e12a10e3af1894eae5fe5cb6
Virtualization: oracle
Operating System: Red Hat Enterprise Linux Server 7.0 (Maipo)
CPE OS Name: cpe:/o:redhat:enterprise_linux:7.0:GA:server

The easiest way to create a Cisco VPN client connection on Redhat 7 Linux is to use vpnc client which is an opensource alternative to Cisco VPN client. Let's start by VPNC installation on RHEL7. The VPNC package is located within EPEL ( Extra Packages for Enterprise Linux 7 ) repository thus first enable EPEL repository:
