Will go to /dev/null unless otherwise redirected. To be sent to the syslog file (such as /var/log/messages),Įxcept for the output of scripts and ifconfig commands, which This option will cause all message and error output It has a lot of useful information, and I am only quoting the first paragraph here: -daemon īecome a daemon after all initialization functions areĬompleted.
#Openvpn for mac via brew manual#
To decide whether or not to use this option (and how you want to use it), I recommend you read the openvpn manual page, especially in the section on -daemon. This is specific to openvpn-most programs do not support a -daemon option, though many server programs do have some such option. Therefore, in any situation where you know you want openvpn to start running in the background, and you know you won't want to bring it back into the foreground, you should strongly consider the method of invoking it with the -daemon option. But if openvpn couldn't immediately daemonize, then all the other ways of immediately running it in the background will break, too. And that depends, in part, on what is set up in ~/my_connection.ovpn. Whether or not this is appropriate depends on whether or not any interaction must occur after openvpn has been run but before it daemonizes. opvn filename rather than before the argument following -daemon, if any, is interpreted as the name that the daemonized openvpn process should use. Openvpn will run in the background automatically if you run it with the -daemon option: sudo openvpn ~/my_connection.ovpn -daemon Way 3: But for openvpn, you should probably just run it with -daemon.

This works because nothing is running in the background until after sudo has recieved your password (if necessary) and determined that you are permitted to run the command. Most interactive commands willįail to work properly in background mode.
Possible to use shell job control to manipulate background With sudo -b you don't get job control, but in a shell script job control is disabled by default and you shouldn't usually use it.
This is usually a better way, especially if you are putting the command in a script. Instead, you can run sudo itself in the foreground, but pass the -b flag so sudo causes the command to be run in the background. In general, this is usually what you want. This is especially the case for scripting. However, it is usually better to avoid & (and nohup) altogether when you want to run a command in the background with sudo. Then, after that, you can run: sudo openvpn ~/my_connection.ovpn & You can ensure that sudo has a current timestamp when it is used to run your command, by first running: sudo -v Way 1: Make sure sudo has a fresh timestamp. So in this situation, running the command, entering your password, and sending it to the background afterwards is an reasonable way to do it, for interactive use.īut it's not the only way and, as you say, you will not want to do that in a script. But if you run the command in the background by appending & then you won't be shown the password for user: line or given the opportunity to type it in. Under sudo's default configuration, if you haven't recently entered your password for sudo in the same terminal (or have logged out and back in on that terminal) then it will ask for your password. Your command is: sudo openvpn ~/my_connection.ovpn I've tried to append a & to the cpenvpn command and to place nohop in

Since you're running openvpn (and, less specifically, since you wish to run a program as root in the background), the most commonly dispensed information about how to run commands in the background does not address your situation. TL DR: Use sudo -b or, better, openvpn -daemon.
