Linux server operation

  It may be that the server's SSH is broken and cannot be connected directly with secureCRT, so you need to log in from another server and then ssh to this server.

In fact, it is very simple, just slowly began to learn Linux operation, learning a little is a little.

Command: ssh -l usename ip;

 

Such as:

I have logged in to the server whose hostname is po@7969 and directly execute    ssh -l abc    po@7972 ;

Some need to enter a password, I don't need it here, so I jumped directly to the server po@7972.
