Currenlty ssh service is in stop status.when we trying to start this service following error shows;

'/etc/ssh/sshd_config line 23: directive 'protocol' is not allowed within a match block'.

How to fix this issue and start ths ssh service

Here is the first part of the config file:

Add this on line 3:

Match all

You have not ended the Match block.

The first two lines have apparently been added as part of a chroot jail set-up for user restricted_user_1.

Since that user is apparently related to system backups, I think it's kind of important... so a better solution would be to move those two lines to the end of the sshd_config file instead. That should both avoid the problem with the Protocol 2 line and not break the setup of restricted_user_1 user.

If you use Match blocks in sshd_config, then the ordering of lines in the file is important.

• you should place any configuration lines that should be the default settings before any Match blocks. Some configuration options cannot be used within Match blocks: those options should always be placed before any Match block.


• when a Match block begins, it will only end either at the start of another Match block or at end-of-file. A Match block can be used to conditionally override some of the default settings. Anything after the first Match block until end-of-file will belong to one Match block or another.
