WhoWhatWhen
mercutioare laptops usually really bad from certain directions with wifi?
if i spin around in my chair the speed changes a LOT
for a wireless access point in the same room.
like where it was resting is 34MB/secish, somewhere magical was 50+MB/sec, and while spinning it got down to under 2MB/sec..
and got like 20MB/sec at one place.

brycecSo very dependent on thge ibdividual kaptop, and specvifixasllt the antenna design

mercutioi thought my typing was bad :)
yeah i suspect it's antenna design, i hadn't really paid attention to it before
[04:53]
brycecmost put a vert omni in the lid
along the edges
if its in the base, or possibnly behind the lcd, you will see bad behaviour
also if the asnt is not attascvhed, has becvome disconn from the card etc

mercutioahh so that could mean that 180 degrees totally changes performance [05:31]
plettIf it's 11n with the MIMO multiple antenna stuff on both laptop and AP end then it /should/ be immune from that [05:34]

grodysh1t - does anyone have a good read on breaking out of freebsd jails on an older 10 box?
locked myself inside my jail and forgotten the hosts root password and have no other means of getting it
well, i has root in the jail - but the usual tricks leave me with a useless shell

ugh.. on a plus side, the opensshd running on host is vulnerable to KbdInteractiveDevices - so i shoud be able to crack it in a few hours
(and who says using keyboard interactive only is bad) :D
thankyou kingcope

mercutioplett: 802.11ac so that should do mimo?
802.11g can'd do 300+ megabit/sec
grody: can't you just reboot it ?

grodymercutio, boot -s would fail, ttys are all set to insecure
i know roughly what the password should be, but it's in what concatination i used
[18:31]
mjp_boot off rescue media [18:33]
grodyno physical access, no oob/vnc
crackers must be very patient people is all i can say
[18:34]
mjp_ahh, well you should probably get one of those things for cases like this heh [18:36]
grodyi swore i backdoored it tbh, but the only thing open on the host is sshd [18:36]
mike-burnsDidn't FreeBSD have an sshd exploit a month back? Did you patch for that already? [18:37]
grodyyea im usiing that to brute password
well, dictionary
[18:37]
mjp_and you have PermitRootLogin set to yes? [18:37]
grodynope
just keyboard auth
[18:37]
mjp_so how are you going to get root? [18:38]
grodyif my maths are right, this should be done in about 17 hours
user has sudo access
cant get any access to host sshd, only the jails
[18:38]
mjp_ah [18:39]
grodyonly wanted to pull a pdf i had stored on the user homedir too
just hope sshd doesn't bail out
then i will have to somehow force a reboot, which im not sure how i'll managed
grody wished he was a hacker at times like this
[18:41]
mjp_or a better sysadmin that backups up their data and has OOB management :p [18:45]
grodyhaha :P
in my defense, the whole point of this rig was remote access only, else no dice - does geli too, but that could be easily .... hmmm, you just made me realise - if i can force a reboot, i can get access to it's limited shell
thats the backdoor
im petty damned sure i can cause a kernel panic within the jail
my screen has the stack vuln
