edit file sudoers
sudo nano /etc/sudoers or sudo visudo
and modify
%sudo ALL=(ALL) ALL
to
%sudo ALL=(ALL) NOPASSWD: ALL
and add following line to the end of the file:
user ALL=NOPASSWD: ALL
When editing sudoers, it’s necessary to be very careful. Any error cause that you will not be able to edit this file anymore and also not to use sudo ;-).
Here are links how to fix it (verified 😉 )
Use -g swith after -L section to forward ports to whole network
autossh -M 40008 -f -N user@server -L 33061:127.0.0.1:3306 -g -L 6380:127.0.0.1:6380 -o "ServerAliveInterval 60" -o "ServerAliveCountMax 3" -o BatchMode=yes -o StrictHostKeyChecking=no -i /root/.ssh/id_rsa
Configuration file : /etc/init/autossh.conf
Start service:
sudo service autossh start
//execute nginx //stop nginx -s stop //reload configurations nginx -s reload //reopen log files nginx -s reload
How to connect to remote computer with private key by using ssh:
#register private key ssh-add ~/dev/Private/ludek_vodicka_dsa.openssh #connect to computer and forward local port to remote computer and remote port ssh my-computer.com -p PORT -lUSER -L LOCAL_PORT:REMOTE_COMPUTER:REMOTE_PORT #connect to computer and create SOCKS proxy on port SOCKS_PORT ssh my-computer.com -p PORT -lUSER -D SOCKS_PORT
If your private key was created for Windows, it will probably not work on linux/mac. It’s necessary to convert it by using puttygen (on mac or windows). You need to open it by puttygen and choose “Save as openssh” from menu.

How to customize default terminal prompt which looks like this?
ComputerName Directory UserName$
simply define PS1 variable with required format. To display only full path, use following:
export PS1="\w $"
\d – date\t – time\h – hostname\# – command number\u – username\W – current directory (e.g.: Desktop)\w – current directory path (e.g.: /Users/Admin/Desktop)It’s necessary to configure which parameters are passed to fast-cgi application from nginx server. For this purposes serves fastcgi_param keyword. It’s a good practice to keeps all fastcgi params together. For this purposes nginx has fastcgi.conf file. This file already contains most of useful fastcgi_param bindings.
fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; ...
To include this file use include statement:
location / {
include fastcgi_params;
fastcgi_pass 127.0.0.1:9345;
}
Default configuration pass only default headers to fast-cgi. It’s necessary to add few more configurations statements:
fastcgi_pass_request_headers on;
After that headers are passed as HTTP_* parameters:
HTTP_HEADER1=2222
