서버 랜(hardware) 포트 확인 시

서버 랜카드 설정 후 핑이 안갈 경우,

위의 같이 70-persistent-net.rules 파일의 백업 파일을 만든 후

# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.

위의 굷은 부분을 삭제후 리부링을 함

diff 으로 파일을 비교하여 내용을 확인해보고 다르다면 hardware 문제로 확인을 함

ifconfig와 ifconfig -a로 확인을 해보면 해당 포트가 확인 됨
