Thanks to all. With

# more /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=mypc

#

and

# more /etc/sysconfig/network-scripts/ifcfg-eth0
# Broadcom Corporation NetLink BCM5789 Gigabit Ethernet PCI Express
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=dhcp
HWADDR=00:14:85:38:2c:93
TYPE=Ethernet
DHCP_HOSTNAME=mypc

#

the problem became solved.
