 Posted: Sat Sep 23, 2006 8:10 pm Post subject: bluetooth proximity detection? |
 |
|
My friend mentioned to me that someone he knew had his gentoo set up to detect his bluetooth phone and log him in to his computer when he was in range. I did a few searches but couldn't find any resources in these forums.
Has anyone done this? I was thinking it would be fun to mess around with, maybe even have my computer announce when I get home.
I found a thing called Asterisk@Home that does kind of what I want, I just don't want the phone forawrding stuff. |

Hey thanks for the links. That points me in the right direction. Unfortunately, neither of those two options work. I got them all set up and configured but when one or the other is enabled I can not log in at all.
I also found http://perl.jonallen.info/projects/bluetooth
which seems usefull but I haven't tried it yet. |

How are you configuring pam_blue?
I just finished fighting with pam_usb so I have become somewhat familiar with it. If you don't mind posting your configs here. Perhaps I could help you?

There isn't much documentation on it. This is what I have in the "/etc/security/bluescan.conf" file.
| Code: |
###########################################################
#
# sample bluescan.conf configuration file
# $Id: sample.conf 3 2004-04-18 23:32:18Z pfeifer $
#
###########################################################
general {
# the normal timeout for scanning
# watch out for a to tiny timeslot for scanning
# values between 4 and 15 seconds are valid
timeout = 4;
}
xamindar = {
# bluetooth device name
name = Jared`s LG CU500;
# bluetooth mac address
bluemac = 00:12:56:5A:92:59;
# a seaparate timeout
timeout = 10;
}
|
Also, a question about pam_usb. In the logs it keeps spitting out:
| Code: |
[device.c:74] Directory /proc/scsi/usb-storage-0/ not found
[pam.c:198] Device not valid.
[pam.c:138] Searching the utmp entry for tty tty2...
[pam.c:152] Authentication request from tty2 ()
[device.c:74] Directory /proc/scsi/usb-storage-0/ not found
[pam.c:198] Device not valid.
[pam.c:138] Searching the utmp entry for tty tty2...
[pam.c:152] Authentication request from tty2 ()
[device.c:74] Directory /proc/scsi/usb-storage-0/ not found
[pam.c:198] Device not valid.
|
Shouldn't it be looking for "/proc/scsi/usb-storage/0" instead? |

Hmm, I dunno. You should be using pam_blue though, not pam_usb...
This is what my pam config, I am currently only using pam_usb but you may want to have something similar to this with pam_blue. Obviously you will have to use different parameters.

Here is my /etc/pam.d/system-auth at the moment
| Code: | #%PAM-1.0
#added by me
#auth required /lib/security/pam_blue.so debug
#auth required pam_usb.so force_device=/dev/sda1 fs=vfat check_if_mounted=1 debug=1 log_file=/var/log/pam_usb.log
## possible uses
# 1. Unique
# auth required pam_usb.so
# 2. Alternative
# auth sufficient pam_usb.so
# 3. Additional
# auth required pam_usb.so
auth required pam_env.so
auth sufficient pam_unix.so likeauth nullok
auth required pam_deny.so
account required pam_unix.so
password required pam_cracklib.so difok=2 minlen=8 dcredit=2 ocredit=2 retry=3
password sufficient pam_unix.so nullok md5 shadow use_authtok
password required pam_deny.so
session required pam_limits.so
session required pam_unix.so

Thanks for the help. I guess I'll just mess around with it and hopefully figure out what's wrong. |

Are those commented out by default? Also I found that I had better luck getting the pam_usb to work when I did not specify the "force_device=" once i got it working (pam_usb tries sd* when not force_device is not set) I set up a udev rule to make life easier.
One thing I would suggest trying is this:
change
| Quote: | | #auth required /lib/security/pam_blue.so debug |
to
| Quote: | | auth [bold]sufficient[/bold] pam_blue.so debug |
Setting that as sufficient and placing it above the line containing "pam_unix.so" will set it such that all you need to do is enter your user name, and if the pam_blue auth works you will be logged in. Try this at a TTY
(ie: ctrl+alt+F1) if it does not, then you will still be able to login with your password. Then once you get it all working you can change it back to required.
I am gonna play with pam_blue next weekend (no time now, work/school/gf), if I get it working I will post my config and some troubleshooting tips if I have any.

They are commented because they don't work.
using sufficient is a good tip. I originally had that but nothing changed so I tried using required and then I couldn't log in at all. So at least I now know that the thing is doing *SOMETHING*. I look forward to finding out if you are able to get it working. I will keep on it and post if I have any success. |

OK, my log is saying things such as this when I try to log in.
| Code: | Sep 24 00:37:16 [pam_blue] Can't parse configuration file [_+__�!��_____]!/etc/security/bluesscan.conf
|
I went through the config file and removed all comments and made it as clean as I could but it still does that. Anyone have any ideas? |

Eh, I guess it's time for bed. I tried creating a simple script to announce when I came in but even that doesn't work.
| Code: | #!/bin/bash
ANNOUNCE=/home/xamindar/hello.txt
GOODBYE=/home/xamindar/bye.txt
HOME=`hcitool scan | grep -c 00:12:56:5A:92:59`
if [ "$HOME" == "1" ]; then
festival --tts $ANNOUNCE
fi
if [ "$HOME" == "0" ]; then
festival --tts $GOODBYE
fi
|
fextival spits out the following in the console:
| Code: | xamindar@lain ~/Desktop $ ./home_announce.sh
1/.esd_auth: No such file or directory
ESD: error writing - Bad file descriptor
|
What a frustrating night. |

Check the permissions on the config file.

I tried making it world everything and it still did it. Oh well. It must be outdated. |

Have you tried contacting the original developer?

Yeah, I sent an email to him. We'll see. I did end up getting a fun little script working that will welcome me home when I enter my room with my phone. Used flite instead of stupid festival and it worked. So I'm content with that for now. I'll mess around with bash scripting in the next week and try to make something more usefull.
And I did finally get the usb authentication working. Thanks to your suggestions. Nice to be able to plug it in and not need a password to login. |

EDIT: Nevermind, I went ahead and just did it manually...can't get it to work either  |

Do you get the same errors in your everything log as I do? Something about not being able to parse the config? |

yup!
| Code: | | Sep 26 03:47:17 localhost pam_blue[15885]: Can't parse configuration file [XÀ ˆ»ÊMÐ ]!/etc/security/bluesscan.conf |
The documentation for this isn't great, been trying to set up an sms system too, not having much luck there either though. |

i'm finding pam_blue-0.9.0 can't parse a configuration file with username "anna-maria". |
