After installing ubuntu, there is no ssh service and ftp service by default. We need to solve this problem by ourselves.
SSH
Update software list and software
sudo apt-get update
sudo apt-get upgrade
install ssh
sudo apt-get install ssh
start ssh service
sudo /etc/init.d/ssh start
Modify the ssh service configuration file
sudo vim /etc/ssh/sshd_config
Find the configuration item and modify it to (this item is to allow root login)
PermitRootLogin yes
Modify the root password, I don’t know why you can’t log in as root without modifying it
sudo passwd root
Restart the ssh service after modification
service sshd restart # 或者
/etc/initd.d/sshd restart
FTP
Install ftp service
sudo apt-get install vsftpd
Modify the ftp configuration file
sudo vim /etc/vsftpd.conf
Find the configuration item and modify it to
local_enable=YES
write_enable=YES
Modify the ftp configuration file. This configuration file needs to comment out the root user so that root can log in.
sudo vim /etc/ftpusers
Restart the ftp service after modification
service vsftpd restart # 或者
/etc/initd.d/vsftpd restart
open port
Both ftp and ssh require ports. The default port for ftp is 21, and the default port for ssh is 22. These ports are closed by default in the firewall, and we need to open them manually.
sudo ufw allow 20/tcp
sudo ufw allow 21/tcp
sudo ufw allow 22/tcp
You also need to restart the service after opening the port
terminal connection
After setting these, we can connect to our server in terminal software such as xft and xshell.
The address of the host can ifconfogbe viewed from the host with the command
xftp settings
xshell settings
