Get vlan using snoop

rdircio

You could use this script snoopdcp.sh, usage is like this:

# ./snoopdcp.sh nxge1

The script goes like this:

#!/bin/bash

Interface=$1

if [[ -z "$Interface" ]]
then
  echo "[FATAL]Usage $0 "
  exit 1
fi


#snoopfile=$(mktemp /tmp/snoopy.XXXX)
snoopfile=/tmp/snoopy.XXXX.$$
snoop -d $Interface -c 1 -vv  -o $snoopfile 'dst 01:00:0c:cc:cc:cc and length > 50'
instr=$(snoop -i $snoopfile  -x 26 | nawk -F: ' { print $2 } ' |  cut -b1-41|  sed -e 's/ //g' | nawk 'BEGIN {ORS=""} {print toupper($1)}')
rm -f -- $snoopfile

while  [[ -n "$instr" ]]
do
  typ=`echo $instr | cut -b1-4`
  lhex=`echo $instr | cut -b5-8`
  length=$(echo "ibase=16; $lhex*2" | bc)
  next=$(echo "ibase=16; $lhex*2+1" | bc)
  if [ $length -gt 8 ]
  then
    texthex=`echo $instr | cut -b9-$length`
  else
    texthex=""
  fi
  #  echo "$typ $lhex $texthex"
  if [ $typ == "0001" ]
  then
    printf "Switchname: "
    while  [ $texthex ]
    do
      charhex=`echo $texthex | cut -b1-2`
      chardec=$(echo "ibase=16; $charhex" | bc)
      printf "%b" `printf '\x%x' $chardec 2>/dev/null`
      texthex=`echo $texthex | cut -b3-`
    done
    echo " "
  fi
  if [ $typ == "0003" ]
  then
    printf "Switchport: "
    while  [ $texthex ]
    do
      charhex=`echo $texthex | cut -b1-2`
      chardec=$(echo "ibase=16; $charhex" | bc)
      printf "%b" `printf '\x%x' $chardec 2>/dev/null`
      texthex=`echo $texthex | cut -b3-`
    done
    echo " "
  fi
  if [ $typ == "000A" ]
  then
    echo "VLAN: 0x$texthex $(echo "ibase=16; $texthex" | bc)"
  fi
  if [ $typ == "000B" ]
  then
    echo "Duplex: $texthex"
  fi
  instr=`echo $instr | cut -b$next-`
done

post a tweet to my twitter, using python’s tweepy

rdircio

I automated a twitter update from a random fortune quote, using python and the tweepy library.
First i installed tweepy

# pip install tweepy

Then, created /opt/bin/tweepy

#!/opt/bin/python
import tweepy, sys, commands
quote=commands.getoutput("/opt/bin/fortune")
consumer_key, consumer_secret, access_token, access_token_secret = "xxxxxx", "xxxx", "xxx", "xxx"
auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)
api = tweepy.API(auth)
#print "Successfully logged in as " + api.me().name + "."
api.update_status(quote)

And.. that’s it!. As easy as 1..2..

erase all slices in many disks

rdircio

*WARNING* *WARNING* *WARNING*
*USE WITH EXTREME CARE!!!!!!!!!!!!*
This will delete slices 0,1,3,4,5,6 of many disks (all your “emcpower*” disks) in your solaris system:

echo | format | grep -i emcpower | awk '{ print $2 }'| while read d;do
printf "p\np\n0\n\n\n0\n0\nlabel\ny\nquit\n" |format -d $d
printf "p\np\n1\n\n\n0\n0\nlabel\ny\nquit\n" |format -d $d
printf "p\np\n3\n\n\n0\n0\nlabel\ny\nquit\n" |format -d $d
printf "p\np\n4\n\n\n0\n0\nlabel\ny\nquit\n" |format -d $d
printf "p\np\n5\n\n\n0\n0\nlabel\ny\nquit\n" |format -d $d
printf "p\np\n6\n\n\n0\n0\nlabel\ny\nquit\n" |format -d $d
done
