This article mainly introduces the solution to the rejection of winscp connection, which is very detailed and has a certain reference value. Interested friends must read it!

Solutions: 1, use the "sudo ufw disable" command to turn off the firewall; 2, use the "sudo / etc/init.d/ssh restart" command to turn on the remote service; 3, open 22 port numbers.

If the winscp connection is denied, you can try the following methods:

1) enable | disable the firewall (need to be turned off here)

Sudo ufw enable | disable

2) enable remote service

Enter: service sshd start in the terminal interface.

The results show that: ssh:unrecognized service.

Enter the view command: service ssh status

The display is also unrecognized service.

Turn on remote services:

Terminal interface type: sudo / etc/init.d/ssh restart

(or sudo / etc/init.d/ssh start)

3) Port number 22 should be opened

Sudo vi / etc/ssh/ssh_config

If a ROOT permission connection is denied

Sudo vi / etc/ssh/sshd_config

Find PermitRootLogin no and change it to yes.

Restart the sshd service

Service sshd restart, remember to restart!

Success!
