I want to get my BOINC manager start with anoter computer already loged in.
How can I do that?

Hi Bengt - welcome to BOINC forum.

boincmgr --help
shows

Usage: boincmgr [-h] [--verbose] [-a] [-e <str>] [-d <str>] [-n <str>] [-g <str>] [-p <str>] [-b <str>] [-i] [-c] [-m]
  -h, --help              	show this help message
  --verbose               	generate verbose log messages
  -a, --autostart         	BOINC Manager was started by the operating system automatically
  -e, --clientdir=<str>   	Directory containing the BOINC Client executable
  -d, --datadir=<str>     	BOINC data directory
  -n, --namehost=<str>    	Host name or IP address
  -g, --gui_rpc_port=<str>	GUI RPC port number
  -p, --password=<str>    	Password
  -b, --boincargs=<str>   	Startup BOINC with these optional arguments
  -i, --insecure          	disable BOINC security users and permissions
  -c, --checkskins        	set skin debugging mode to enable skin manager error messages
  -m, --multiple          	multiple instances of BOINC Manager allowed

So boincmgr --namehost=<IP or hostname>

Should work.

Thanks, almost
I forgot to tell its Windows 10 pro
I want to monitor my linux box from my main computer No jobs are running here

Orginal startup-line
"C:\Program Files\BOINC\boincmgr.exe" /a /s
Works of curse

My new line
"C:\Program Files\BOINC\boincmgr.exe" /a /s /n=192.168.1.1
It hangs when I try to select computer manualy
Or
"C:\Program Files\BOINC\boincmgr.exe" /n=192.168.1.1
Does not work, this one does not hang, but does not log onto it

Whay does it not work?

Whay does it not work?

either use --namehost=<str>
or
/n <str>

not /n=<str>

see http://boincfaq.mundayweb.com/index.php?view=591&language=1

Not the end of the world, but it will not work

Not this line
"C:\Program Files\BOINC\boincmgr.exe" /a /s /n 192.168.1.1
Or this
"C:\Program Files\BOINC\boincmgr.exe" /a /s /n boinc.sm7jqb.lan

This is not posible in the registry
"C:\Program Files\BOINC\boincmgr.exe" /a /s --namehost=boinc.sm7jqb.lan
It clames this long option '-namehost' does not exist

I have to live wit it this manual way, BOINC are running in my server 24/7 anyway

If the remote host has GUI RPC password set then that needs to be included on the command line.

No PSW is set, all hapends inside a private network
