First, Reason:Before because the server can only login, and limit the root account login, so ssh through all the server, to achieve the public key forward SCP free password, etc., greatly facilitate the management of the server.Recently there is a need to do offsite backup of data. The simplest use of SCP script, but script manual execution is OK, put crontab does not work properly.Second, the solution:Script execution failed, immediately thought to print verbose log debug, that scp-v then read

other system's user name and password calculation, import ucenter uc_members table, to achieve user migration. For example, if the original system uses an algorithm such as MD5 (password) to save the password, then the program randomly generated salt, and then calculate the cumulative MD5, so it is easy to calculate the user in the Ucenter user password hash value, so as to achieve seamless user migration. However, if the original system is using MD5 (Password+salt) to save the password, it wil
