That's exactly what I do. I turn on my emergency system every couple |
| 9 |
of weeks, "emerge --sync" and "emerge --ask --deep --update --world", |
| 10 |
run etc-update if necessary and then shut down. I have a honking big |
| 11 |
19" CRT on my desk at home, and the KVM is used elsewhere. The machine |
| 12 |
name is m450 (450 mhz PIII). My main machine is m3000 (AMD64 3000+). |
| 13 |
There is an ordinary user "waltdnes" on m450. /etc/sudoers on m450 |
| 14 |
contains the following line... |
| 15 |
|
| 16 |
waltdnes m450 = (root) NOPASSWD: /sbin/poweroff |
| 17 |
|
| 18 |
I have a short script ~/bin/stopm450 on m3000 ... |
| 19 |
|
| 20 |
#!/bin/bash |
| 21 |
ssh waltdnes@m450 sudo /sbin/poweroff |
| 22 |
|
| 23 |
To shut down... |
| 24 |
1) via ssh shut down unnecessary programs on m450 |
| 25 |
2) exit all ssh sessions to m450 |
| 26 |
3) stopm450 |
| 27 |
