Using expect script to do an ssh from a remote machine -


i new expect scripts , have use case in need ssh machine in have done ssh using expect script. code snippet

#!/usr/bin/expect -f set timeout 60 spawn ssh username@machine1.domain.com  expect "password: " send "password\r"  send "\r" # successful. able login first machine  set timeout 60 spawn ssh username@machine2.domain.com  #this fails

this takes amount of time , fails saying ssh: connect host machine2.domain.com port 22: operation timed out. understand 22 default port on ssh runs , can manually override giving -p option ssh.

if try ssh independently without expect script prompt asks me enter (yes/no). correct port being picked if execute ssh directly without expect script. if not need enter port number on shell why needed enter port number if using expect script.

that point, don't spawn new ssh: spawn creates new process on local machine. send command remote server

#!/usr/bin/expect -f set timeout 60 spawn ssh username@machine1.domain.com  expect "password: " send "password\r"  send "\r" # successful. able login first machine  # @ point, carry on scripting first ssh session: send "ssh username@machine2.domain.com\r" expect ...

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
