fstab

/etc/fstab 파일의 내용은 다음과 같다. options 값이 바뀌었음.

jinia@jin:~$ sudo cat /etc/fstab

network

회사에서 ping이 나가는지만 체크하면 될듯.

ping 192.168.41.1
ping www.solutionpot.co.kr

/etc/netplan/01-netcfg.yaml 파일에 네트워크 설정 정보는 들어가 있음.
nameservers의 addresses는 xxx.xxx.xxx.xxx 로 되어있으니, 적당히 본인이 사용하는 DNS ip를 적길..

jinia@jin:~$ cat /etc/netplan/01-netcfg.yaml 
# This file describes the network interfaces available on your system
# For more information, see netplan(5).

fileserver

윈도우에서는 탐색기에서 네트워크 드라이브로 다음과 같이 연결해서 사용했는데. ubuntu는 없는지라..

\\xxx.xxx.xxx.xxx\swdev

다음과 같이 ssh로 연결해서 사용하면 된다. 파일 서버 IP는 203. 어쩌고였음.

ssh fxxxxx@xxx.xxx.xxx.xxx
cd /media/data/swdev

booting disk

Startup Disk Creator

iso 파일만 있다면 ubuntu에서 만들꺼라면 tutorial 따라 만들면 된다.
