about putty auto close

Putty-auto-close may caused by server error like "too many logins to user 'xxx' ".

You can fix it by these steps:

  1. login to server as admin

  2. vim /etc/security/limits.conf

  3. modify the limitation or add new one line as :

@xxx hard maxlogins 100

and I'm sure you must have known what the xxx and 100 mean.
