I have two linux machines, A and B. A is master and B is slave. Besides, B is behind proxy. In B , I have set http_proxy and socks_proxy env variable.
However, B cannot connect to A and report
ERROR CODE 2013
error connecting to master 'firstname.lastname@example.org:3306' Slave_IO_Running No Slave_SQL_Running Yes
I try to fix it in whole days but still in vain. Whats' wrong, thank you.
