Next time you are leaching off of someone else's wifi use this command before you start your bittorrent ...for legitimate files only of course.
It creates a hexidecimal string using md5sum from the first few lines of /dev/urandom and splices it into the proper MAC address format. Then it changes your MAC and resets your wireless (wlan0:0).
This is a quick line to stream in the latest offerings of your favorite netcasts/podcasts. You will need to have a file named netcast.txt in the directory you run this from. This file should have one and only one of your netcast's/podcst's url per line.
When run the line grabs the offering on the top of the netcast/podcast stack and end it over , quietly, to vlc.
Since I move around computers during the day I wanted an easy way to listen to my daily dose of news and such without having to worry about downloading to whatever machine I am on. This is just a quick grab and stream of whats current.
Future plans... have the list of netcasts be read from the web. possibly an rss or such. I use greader so there might be a way to use it as the source so as not to have to muck with multiple lists
You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token.
This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use:
`awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'`
You must adapt the command line to include:
* $MFA_IDis ARN of the virtual MFA or serial number of the physical one
* TTL for the credentials
To show ipv6 instead, use [[ -6 ]] instead of [[ -4 ]]
$ip -o -6 a s | awk -F'[ /]+' '$2!~/lo/{print $4}'
To show only the IP of a specific interface, in case you get more than one result:
$ip -o -4 a s eth0 | awk -F'[ /]+' '$2!~/lo/{print $4}'
$ip -o -4 a s wlan0 | awk -F'[ /]+' '$2!~/lo/{print $4}'
time read -sn1 (s:silent, n:number of characters. Press any character to stop)
