Change the mac address of your network adapter.
sudo ifconfig wlan0 down && sudo ifconfig wlan0 hw ether 00:11:22:33:44:55 && sudo ifconfig wlan0 up |
This will change the mac address of your network interface instantly. Below is an example.
homer@deusexmachina ~ $ sudo ifconfig eth0 down && sudo ifconfig eth0 hw ether 00:11:22:33:44:55 && sudo ifconfig eth0 up [sudo] password for homer: homer@deusexmachina ~ $ ifconfig eth0 Link encap:Ethernet HWaddr 00:11:22:33:44:55 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) |
Another way to change your mac address. Using the macchanger utility.
homer@deusexmachina ~ $ sudo macchanger -m DE:AD:BE:EF:00:00 eth0 Permanent MAC: 00:13:46:3a:02:83 (D-link Corporation) Current MAC: 00:11:22:33:44:55 (Cimsys Inc) New MAC: de:ad:be:ef:00:00 (unknown) |
Create a HTTP file server for a directory. This is good for quickly sharing the contents of a folder from your Linux machine to the Internet or a LAN.
python -m SimpleHTTPServer |
Ping an ipv6 address. The ping6 command handles this admirably.
homer@deusexmachina ~ $ ping6 2001:470:1f06:1b5::2 PING 2001:470:1f06:1b5::2(2001:470:1f06:1b5::2) 56 data bytes 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=1 ttl=64 time=0.046 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=2 ttl=64 time=0.050 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=3 ttl=64 time=0.050 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=4 ttl=64 time=0.051 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=5 ttl=64 time=0.054 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=6 ttl=64 time=0.054 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=7 ttl=64 time=0.062 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=8 ttl=64 time=0.055 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=9 ttl=64 time=0.057 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=10 ttl=64 time=0.054 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=11 ttl=64 time=0.055 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=12 ttl=64 time=0.053 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=13 ttl=64 time=0.054 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=14 ttl=64 time=0.058 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=15 ttl=64 time=0.054 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=16 ttl=64 time=0.054 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=17 ttl=64 time=0.055 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=18 ttl=64 time=0.054 ms 64 bytes from 2001:470:1f06:1b5::2: icmp_seq=19 ttl=64 time=0.054 ms ^C --- 2001:470:1f06:1b5::2 ping statistics --- 19 packets transmitted, 19 received, 0% packet loss, time 17996ms rtt min/avg/max/mdev = 0.046/0.053/0.062/0.010 ms |
