How to set wake up on slackware linux system.

1) Enable wake up from lan, in BIOS
2) in slack­ware sys­tem enable wake up from lan on inter­face by this command

 ethtool -s eth0 wol g 

I added this com­mand direct­ly to /etc/rc.d/rc.inet1.conf
wol_slackware1

After that, i restart­ed inet1

/etc/rc.d/rc.inet1 stop 
/etc/rc.d/rc.inet1 start

3) And, now easy shut­down in halt mode

 shutdown -t1 -h now

4) Now, you can wake up some free soft­ware from oth­er machin. 
For me work­ing only spe­cif­ic MAC address, broad­cast FF:FF:FF:FF:FF not working.
