Operating Systems BSD MAC at @reboot, like some cellphone Post 302989542 by 1in10 on Saturday 14th of January 2017 05:04:22 AM

MAC at @reboot, like some cellphone

I want to change my MAC at reboot, so making it a cron job like the following in BSD.
Can I do this in the jail for the user, setting it as a command or should it be a script?

I would set it as a command

Code:
openssl rand -hex 6 | sed 's/\(..)/\1:/g; s/.$//'

just to test it, it works.


To make things easier, blinded by the light, I just took the macchanger script from my linux distro and set it already unpacked in the folder of
Code:
/home/name of the user/sbin/

setting the flags and doing it at or @reboot.

It works fine with just the command line!!!!


Code:
@reboot  usernamesomebody    openssl rand -hex 6 | sed 's/\(..)/\1:/g; s/.$//'

I am asking this, because the BSD handbook tells me to try it first as a homebrew script in the really
special environment, that is giving me a headache like the following

Code:
env -i SHELL=/bin/sh PATH=/etc:/bin:/sbin:/usr/bin:/usr/sbin HOME=

And my second question is, would it be better to set it in the system crontab
Code:
/etc/crontab

or just user crontab?

So if someone can help me out, thanks in advance!!!

NAME
irsend - basic LIRC program to send infra-red commands SYNOPSIS
irsend [options] DIRECTIVE REMOTE CODE [CODE...] DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES

/etc/lirc/lircd.conf Default lircd configuration file. It should contain all the remotes, their infra-red codes and the corresponding timing and wave- form details. DIAGNOSTICS
If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics: "irsend: could not connect to socket" "irsend: Connection refused" (or "Permission denied"). SEE ALSO
